+ <refsect1><title>Description</title>
+ <para>udev supplies the system software with device events, manages permissions
+ of device nodes and may create additional symlinks in the <filename>/dev</filename>
+ directory, or renames network interfaces. The kernel usually just assigns unpredictable
+ device names based on the order of discovery. Meaningful symlinks or network device
+ names provide a way to reliably identify devices based on their properties or
+ current configuration.</para>
+
+ <para>The udev daemon, <citerefentry><refentrytitle>udevd</refentrytitle>
+ <manvolnum>8</manvolnum></citerefentry>, receives device uevents directly from
+ the kernel whenever a device is added or removed from the system, or it changes its
+ state. When udev receives a device event, it matches its configured set of rules
+ against various device attributes to identify the device. Rules that match may
+ provide additional device information to be stored in the udev database or
+ to be used to create meaningful symlink names.</para>
+
+ <para>All device information udev processes is stored in the udev database and
+ sent out to possible event subscribers. Access to all stored data and the event
+ sources is provided by the library libudev.</para>
+ </refsect1>
+
+ <refsect1><title>Configuration</title>
+ <para>udev configuration files are placed in <filename>/etc/udev</filename>
+ and <filename>/usr/lib/udev</filename>. All empty lines or lines beginning with
+ '#' are ignored.</para>
+
+ <refsect2><title>Configuration file</title>
+ <para>udev expects its main configuration file at <filename>/etc/udev/udev.conf</filename>.
+ It consists of a set of variables allowing the user to override default udev values.
+ The following variables can be set:</para>
+ <variablelist>
+ <varlistentry>
+ <term><option>udev_root</option></term>
+ <listitem>
+ <para>Specifies where to place the device nodes in the filesystem.
+ The default value is <filename>/dev</filename>.</para>
+ </listitem>
+ </varlistentry>
+
+ <varlistentry>
+ <term><option>udev_log</option></term>
+ <listitem>
+ <para>The logging priority. Valid values are the numerical syslog priorities
+ or their textual representations: <option>err</option>, <option>info</option>
+ and <option>debug</option>.</para>
+ </listitem>
+ </varlistentry>
+ </variablelist>
+ </refsect2>
+
+ <refsect2><title>Rules files</title>
+ <para>The udev rules are read from the files located in the
+ system rules directory <filename>/usr/lib/udev/rules.d</filename>,
+ the volatile runtime directory <filename>/run/udev/rules.d</filename>
+ and the local administration directory <filename>/etc/udev/rules.d</filename>.
+ All rules files are collectively sorted and processed in lexical order,
+ regardless of the directories in which they live. However, files with
+ identical file names replace each other. Files in <filename>/etc</filename>
+ have the highest priority, files in <filename>/run</filename> take precedence
+ over files with the same name in <filename>/lib</filename>. This can be
+ used to override a system-supplied rules file with a local file if needed;
+ a symlink in <filename>/etc</filename> with the same name as a rules file in
+ <filename>/lib</filename>, pointing to <filename>/dev/null</filename>,
+ disables the rules file entirely.</para>
+
+ <para>Rule files must have the extension <filename>.rules</filename>; other
+ extensions are ignored.</para>
+
+ <para>Every line in the rules file contains at least one key-value pair.
+ There are two kind of keys: match and assignment.
+ If all match keys are matching against its value, the rule gets applied and the
+ assignment keys get the specified value assigned.</para>
+
+ <para>A matching rule may rename a network interface, add symlinks
+ pointing to the device node, or run a specified program as part of
+ the event handling.</para>
+
+ <para>A rule consists of a comma-separated list of one or more key-value pairs.
+ Each key has a distinct operation, depending on the used operator. Valid
+ operators are:</para>
+ <variablelist>
+ <varlistentry>
+ <term><option>==</option></term>
+ <listitem>
+ <para>Compare for equality.</para>

+ </listitem>
+ </varlistentry>
+ </variablelist>
+
+ <para>The following key names can be used to match against device properties.
+ Some of the keys also match against properties of the parent devices in sysfs,
+ not only the device that has generated the event. If multiple keys that match
+ a parent device are specified in a single rule, all these keys must match at
+ one and the same parent device.</para>

+# Ok, we probably need a little explanation here for what the two lines above
+# are good for.
+#
+# The story goes like this: when ALSA registers a new sound card it emits a
+# series of 'add' events to userspace, for the main card device and for all the
+# child device nodes that belong to it. udev relays those to applications,
+# however only maintains the order between father and child, but not between
+# the siblings. The control device node creation can be used as synchronization
+# point. All other devices that belong to a card are created in the kernel
+# before it. However unfortunately due to the fact that siblings are forwarded
+# out of order by udev this fact is lost to applications.
+#
+# OTOH before an application can open a device it needs to make sure that all
+# its device nodes are completely created and set up.
+#
+# As a workaround for this issue we have added the udev rule above which will
+# generate a 'change' event on the main card device from the 'add' event of the
+# card's control device. Due to the ordering semantics of udev this event will
+# only be relayed after all child devices have finished processing properly.
+# When an application needs to listen for appearing devices it can hence look
+# for 'change' events only, and ignore the actual 'add' events.
+#
+# When the application is initialized at the same time as a device is plugged
+# in it may need to figure out if the 'change' event has already been triggered
+# or not for a card. To find that out we store the flag environment variable
+# SOUND_INITIALIZED on the device which simply tells us if the card 'change'
+# event has already been processed.

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term "modification".) Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b) You must cause any work that you distribute or publish, that in
- whole or in part contains or is derived from the Program or any
- part thereof, to be licensed as a whole at no charge to all third
- parties under the terms of this License.
-
- c) If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display an
- announcement including an appropriate copyright notice and a
- notice that there is no warranty (or else, saying that you provide
- a warranty) and that users may redistribute the program under
- these conditions, and telling the user how to view a copy of this
- License. (Exception: if the Program itself is interactive but
- does not normally print such an announcement, your work based on
- the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
- a) Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of Sections
- 1 and 2 above on a medium customarily used for software interchange; or,
-
- b) Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a medium
- customarily used for software interchange; or,
-
- c) Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with such
- an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable. However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
- 5. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all. For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded. In such case, this License incorporates
-the limitation as if written in the body of this License.
-
- 9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

-
- END OF TERMS AND CONDITIONS
-
- How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License along
- with this program; if not, write to the Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) year name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License. Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- <signature of Ty Coon>, 1 April 1989
- Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs. If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library. If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-the (/usr)/lib/udev/ directory, to install their rule helper and udev
-rule files.

-Default udev rules and persistent device naming rules may be required
-by other software that depends on the data udev collects from the
-devices.

-udev 182
-========
-Rules files in /etc/udev/rules.s/ with the same name as rules files in
-/run/udev/rules.d/ now always have precedence. The stack of files is now:
-/usr/lib (package), /run (runtime, auto-generated), /etc (admin), while
-the later ones override the earlier ones. In other words: the admin has
-always the last say.
-
-USB auto-suspend is now enabled by default for some built-in USB HID
-devices.
-
-/dev/disk/by-path/ links are no longer created for ATA devices behind
-an 'ATA transport class', the logic to extract predictable numbers does
-not exist in the kernel at this moment.
-
-/dev/disk/by-id/scsi-* compatibility links are no longer created for
-ATA devices, they have their own ata-* prefix.
-
-The s390 rule to set mode == 0666 for /dev/z90crypt is is removed from
-the udev tree and will be part of s390utils (or alternatively could be
-done by the kernel driver itself).
-
-The udev-acl tool is no longer provided, it will be part of a future
-ConsoleKit release. On systemd systems, advanced ConsoleKit and udev-acl
-functionality are provided by systemd.
-
-udev 181
-========
-Require kmod version 5.
-
-Provide /dev/cdrom symlink for /dev/sr0.
-
-udev 180
-========
-Fix for ID_PART_ENTRY_* property names, added by the blkid built-in. The
-fix is needed for udisk2 to operate properly.
-
-Fix for skipped rule execution when the kernel has removed the device
-node in /dev again, before the event was even started. The fix is needed
-to run device-mapper/LVM events properly.
-
-Fix for the man page installation, which was skipped when xsltproc was not
-installed.
-
-udev 179
-========
-Bugfix for $name resolution, which broke at least some keymap handling.
-
-udev 178
-========
-Bugfix for the firmware loading behavior with kernel modules which
-try to load firmware in the module_init() path. The blocked event
-runs into a timout now, which should allow the firmware to be loaded.
-
-Bugfix for a wrong DEVNAME= export, which breaks at least the udev-acl
-tool.
-
-Bugfix for missing ID_ properties for GPT partitions.
-
-The RUN+="socket:.." option is deprecated and should not be used. A warning
-during rules parsing is printed now. Services which listen to udev events,
-need to subscribe to the netlink messages with libudev and not let udev block
-in the rules execution until the message is delivered.
-
-udev 177
-========
-Bugfix for rule_generator instalation.
-
-udev 176
-========
-The 'devtmpfs' filesystem is required now, udev will not create or delete
-device nodes anymore, it only adjusts permissions and ownership of device
-nodes and maintains additional symlinks.
-
-A writable /run directory (ususally tmpfs) is required now for a fully
-functional udev, there is no longer a fallback to /dev/.udev.
-
-The default 'configure' install locations have changed. Packages for systems
-with the historic / vs. /usr split need to be adapted, otherwise udev will
-be installed in /usr and not work properly. Example configuration options
-to install things the traditional way are in INSTALL.
-
-The default install location of the 'udevadm' tool moved from 'sbin'
-to /usr/bin. Some tools expect udevadm in 'sbin', a symlink to udevadm
-needs to be manually created if needed, or --bindir=/sbin be specified.
-
-The expected value of '--libexecdir=' has changed and must no longer contain
-the 'udev' directory.
-
-Kernel modules are now loaded directly by linking udev to 'libkmod'. The
-'modprobe' tool is no longer executed by udev.
-
-The 'blkid' tool is no longer executed from udev rules. Udev links
-directly to libblkid now.
-
-Firmware is loaded natively by udev now, the external 'firmware' binary
-is no longer used.
-
-All built-in tools can be listed and tested with 'udevadm test-builtin'.
-
-The 'udevadm control --reload-rules' option has been renamed to '--reload'.
-It now also reloads the kernel module configuration.
-
-The systemd socket files use PassCredentials=yes, which is available in
-systemd version 38.
-
-The udev build system only creates a .xz tarball now.
-
-All tabs in the source code used for indentation are replaced by spaces now. :)
-
-udev 175
-========
-Bugfixes.
-
-udev 174
-========
-Bugfixes.
-
-The udev daemon moved to /lib/udev/udevd. Non-systemd init systems
-and non-dracut initramfs image generators need to change the init
-scripts. Alternatively the udev build needs to move udevd back to
-/sbin or create a symlink in /sbin, which is not done by default.
-
-The path_id, usb_id, input_id tools are built-in commands now and
-the stand-alone tools do not exist anymore. Static lists of file in
-initramfs generators need to be updated. For testing, the commands
-can still be executed standalone with 'udevadm test-builtin <cmd>'.
-
-The fusectl filesystem is no longer mounted directly from udev.
-Systemd systems will take care of mounting fusectl and configfs
-now. Non-systemd systems need to ship their own rule if they
-need these filesystems auto-mounted.
-
-The long deprecated keys: SYSFS=, ID=, BUS= have been removed.
-
-The support for 'udevadm trigger --type=failed, and the
-RUN{fail_event_on_error} attribute was removed.
-
-The udev control socket is now created in /run/udev/control
-and no longer as an abstract namespace one.
-
-The rules to create persistent network interface and cdrom link
-rules automatically in /etc/udev/rules.d/ have been disabled by
-default. Explicit configuration will be required for these use
-cases, udev will no longer try to write any persistent system
-configuration from a device hotplug path.
-
-udev 173
-========
-Bugfixes.
-
-The udev-acl extra is no longer enabled by default now. To enable it,
---enable-udev_acl needs to be given at ./configure time. On systemd
-systems, the udev-acl rules prevent it from running as the functionality
-has moved to systemd.
-
-udev 172
-========
-Bugfixes.
-
-Udev now enables kernel media-presence polling if available. Part
-of udisks optical drive tray-handling moved to cdrom_id: The tray
-is locked as soon as a media is detected to enable the receiving
-of media-eject-request events. Media-eject-request events will
-eject the media.
-
-Libudev enumerate is now able to enumerate a subtree of a given
-device.
-
-The mobile-action-modeswitch modeswitch tool was deleted. The
-functionality is provided by usb_modeswitch now.
-
-udev 171
-========
-Bugfixes.
-
-The systemd service files require systemd version 28. The systemd
-socket activation make it possible now to start 'udevd' and 'udevadm
-trigger' in parallel.
-
-udev 170
-========
-Fix bug in control message handling, which can lead to a failing
-udevadm control --exit. Thanks to Jürg Billeter for help tracking
-it down.
-
-udev 169
-========
-Bugfixes.
-
-We require at least Linux kernel 2.6.32 now. Some platforms might
-require a later kernel that supports accept4() and similar, or
-need to backport the trivial syscall wiring to the older kernels.
-
-The hid2hci tool moved to the bluez package and was removed.
-
-Many of the extras can be --enable/--disabled at ./configure
-time. The --disable-extras option was removed. Some extras have
-been disabled by default. The current options and their defaults
-can be checked with './configure --help'.
-
-udev 168
-========
-Bugfixes.
-
-Udev logs a warning now if /run is not writable at udevd
-startup. It will still fall back to /dev/.udev, but this is
-now considered a bug.
-
-The running udev daemon can now cleanly shut down with:
- udevadm control --exit
-
-Udev in initramfs should clean the state of the udev database
-with: udevadm info --cleanup-db which will remove all state left
-behind from events/rules in initramfs. If initramfs uses
---cleanup-db and device-mapper/LVM, the rules in initramfs need
-to add OPTIONS+="db_persist" for all dm devices. This will
-prevent removal of the udev database for these devices.
-
-Spawned programs by PROGRAM/IMPORT/RUN now have a hard timeout of
-120 seconds per process. If that timeout is reached the spawned
-process will be killed. The event timeout can be overwritten with
-udev rules.
-
-If systemd is used, udev gets now activated by netlink data.
-Systemd will bind the netlink socket which will buffer all data.
-If needed, such setup allows a seemless update of the udev daemon,
-where no event can be lost during a udevd update/restart.
-Packages need to make sure to: systemctl stop udev.socket udev.service
-or 'mask' udev.service during the upgrade to prevent any unwanted
-auto-spawning of udevd.
-This version of udev conflicts with systemd version below 25. The
-unchanged service files will not wirk correctly.
-
-udev 167
-========
-Bugfixes.
-
-The udev runtime data moved from /dev/.udev/ to /run/udev/. The
-/run mountpoint is supposed to be a tmpfs mounted during early boot,
-available and writable to for all tools at any time during bootup,
-it replaces /var/run/, which should become a symlink some day.
-
-If /run does not exist, or is not writable, udev will fall back using
-/dev/.udev/.
-
-On systemd systems with initramfs and LVM used, packagers must
-make sure, that the systemd and initramfs versions match. The initramfs
-needs to create the /run mountpoint for udev to store the data, and
-mount this tmpfs to /run in the rootfs, so the that the udev database
-is preserved for the udev version started in the rootfs.
-
-The command 'udevadm info --convert-db' is gone. The udev daemon
-itself, at startup, converts any old database version if necessary.
-
-The systemd services files have been reorganized. The udev control
-socket is bound by systemd and passed to the started udev daemon.
-The udev-settle.service is no longer active by default. Services which
-can not handle hotplug setups properly need to actively pull it in, to
-act like a barrier. Alternatively the settle service can be unconditionally
-'systemctl'enabled, and act like a barrier for basic.target.
-
-The fstab_import callout is no longer built or installed. Udev
-should not be used to mount, does not watch changes to fstab, and
-should not mirror fstab values in the udev database.
-
-udev 166
-========
-Bugfixes.
-
-New and updated keymaps.
-
-udev 165
-========
-Bugfixes.
-
-The udev database has changed, After installation of a new udev
-version, 'udevadm info --convert-db' should be called, to let the new
-udev/libudev version read the already stored data.
-
-udevadm now supports quoting of property values, and prefixing of
-key names:
- $ udevadm info --export --export-prefix=MY_ --query=property -n sda
- MY_MAJOR='259'
- MY_MINOR='0'
- MY_DEVNAME='/dev/sda'
- MY_DEVTYPE='disk'
- ...
-
-libudev now supports:
- udev_device_get_is_initialized()
- udev_enumerate_add_match_is_initialized()
-to be able to skip devices the kernel has created , but udev has
-not already handled.
-
-libudev now supports:
- udev_device_get_usec_since_initialized()
-to retrieve the "age" of a udev device record.
-
-GUdev supports a more generic GUdevEnumerator class, udev TAG
-handling, device initialization and timestamp now.
-
-The counterpart of /sys/dev/{char,block}/$major:$minor,
-/dev/{char,block}/$major:$minor symlinks are now unconditionally
-created, even when no rule files exist.
-
-New and updated keymaps.
-
-udev 164
-========
-Bugfixes.
-
-GUdev moved from /usr to /.
-
-udev 163
-========
-Bugfixes.
-
-udev 162
-========
-Bugfixes.
-
-Persistent network naming rules are disabled inside of Qemu/KVM now.
-
-New and updated keymaps.
-
-Udev gets unconditionally enabled on systemd installations now. There
-is no longer the need to to run 'systemctl enable udev.service'.
-
-udev 161
-========
-Bugfixes.
-
-udev 160
-========
-Bugfixes.
-
-udev 159
-========
-Bugfixes.
-
-New and fixed keymaps.
-
-Install systemd service files if applicable.
-
-udev 158
-========
-Bugfixes.
-
-All distribution specific rules are removed from the udev source tree,
-most of them are no longer needed. The Gentoo rules which allow to support
-older kernel versions, which are not covered by the default rules anymore
-has moved to rules/misc/30-kernel-compat.rules.
-
-udev 157
-========
-Bugfixes.
-
-The option --debug-trace and the environemnt variable UDEVD_MAX_CHILDS=
-was removed from udevd.
-
-Udevd now checks the kernel commandline for the following variables:
- udev.log-priority=<syslog priority>
- udev.children-max=<maximum number of workers>
- udev.exec-delay=<seconds to delay the execution of RUN=>
-to help debuging coldplug setups where the loading of a kernel
-module crashes the system.
-
-The subdirectory in the source tree rules/packages has been renamed to
-rules/arch, anc contains only architecture specific rules now.
-
-udev 156
-========
-Bugfixes.
-
-udev 155
-========
-Bugfixes.
-
-Now the udev daemon itself, does on startup:
- - copy the content of /lib/udev/devices to /dev
- - create the standard symlinks like /dev/std{in,out,err},
- /dev/core, /dev/fd, ...
- - use static node information provided by kernel modules
- and creates these nodes to allow module on-demand loading
- - possibly apply permissions to all ststic nodes from udev
- rules which are annotated to match a static node
-
-The default mode for a device node is 0600 now to match the kernel
-created devtmpfs defaults. If GROUP= is specified and no MODE= is
-given the default will be 0660.
-
-udev 154
-========
-Bugfixes.
-
-Udev now gradually starts to pass control over the primary device nodes
-and their names to the kernel, and will in the end only manage the
-permissions of the node, and possibly create additional symlinks.
-As a first step NAME="" will be ignored, and NAME= setings with names
-other than the kernel provided name will result in a logged warning.
-Kernels that don't provide device names, or devtmpfs is not used, will
-still work as they did before, but it is strongly recommended to use
-only the same names for the primary device node as the recent kernel
-provides for all devices.
-
-udev 153
-========
-Fix broken firmware loader search path.
-
-udev 152
-========
-Bugfixes.
-
-"udevadm trigger" defaults to "change" events now instead of "add"
-events. The "udev boot script" might need to add "--action=add" to
-the trigger command if not already there, in case the initial coldplug
-events are expected as "add" events.
-
-The option "all_partitons" was removed from udev. This should not be
-needed for usual hardware. Udev can not safely make assumptions
-about non-existing partition major/minor numbers, and therefore no
-longer provide this unreliable and unsafe option.
-
-The option "ignore_remove" was removed from udev. With devtmpfs
-udev passed control over device nodes to the kernel. This option
-should not be needed, or can not work as advertised. Neither
-udev nor the kernel will remove device nodes which are copied from
-the /lib/udev/devices/ directory.
-
-All "add|change" matches are replaced by "!remove" in the rules and
-in the udev logic. All types of events will update possible symlinks
-and permissions, only "remove" is handled special now.
-
-The modem modeswitch extra was removed and the external usb_modeswitch
-program should be used instead.
-
-New and fixed keymaps.
-
-udev 151
-========
-Bugfixes.
-
-udev 150
-========
-Bugfixes.
-
-Kernels with SYSFS_DEPRECATED=y are not supported since a while. Many users
-depend on the current sysfs layout and the information not available in the
-deprecated layout. All remaining support for the deprecated sysfs layout is
-removed now.
-
-udev 149
-========
-Fix for a possible endless loop in the new input_id program.
-
-udev 148
-========
-Bugfixes.
-
-The option "ignore_device" does no longer exist. There is no way to
-ignore an event, as libudev events can not be suppressed by rules.
-It only prevented RUN keys from being executed, which results in an
-inconsistent behavior in current setups.
-
-BUS=, SYSFS{}=, ID= are long deprecated and should be SUBSYSTEM(S)=,
-ATTR(S){}=, KERNEL(S)=. It will cause a warning once for every rule
-file from now on.
-
-The support for the deprecated IDE devices has been removed from the
-default set of rules. Distros who still care about non-libata drivers
-need to add the rules to the compat rules file.
-
-The ID_CLASS property on input devices has been replaced by the more accurate
-set of flags ID_INPUT_{KEYBOARD,KEY,MOUSE,TOUCHPAD,TABLET,JOYSTICK}. These are
-determined by the new "input_id" prober now. Some devices, such as touchpads,
-can have several classes. So if you previously had custom udev rules which e. g.
-checked for ENV{ID_CLASS}=="kbd", you need to replace this with
-ENV{ID_INPUT_KEYBOARD}=="?*".
-
-udev 147
-========
-Bugfixes.
-
-To support DEVPATH strings larger than the maximum file name length, the
-private udev database format has changed. If some software still reads the
-private files in /dev/.udev/, which it shouldn't, now it's time to fix it.
-Please do not port anything to the new format again, everything in /dev/.udev
-is and always was private to udev, and may and will change any time without
-prior notice.
-
-Multiple devices claiming the same names in /dev are limited to symlinks
-only now. Mixing identical symlink names and node names is not supported.
-This reduces the amount of data in the database significantly.
-
-NAME="%k" causes a warning now. It's is and always was completely superfluous.
-It will break kernel supplied DEVNAMEs and therefore it needs to be removed
-from all rules.
-
-Most NAME= instructions got removed. Kernel 2.6.31 supplies the needed names
-if they are not the default. To support older kernels, the NAME= rules need to
-be added to the compat rules file.
-
-Symlinks to udevadm with the old command names are no longer resolved to
-the udevadm commands.
-
-The udev-acl tool got adopted to changes in ConsoleKit. Version 0.4.1 is
-required now.
-
-The option "last_rule" does no longer exist. Its use breaks too many
-things which expect to be run from independent later rules, and is an idication
-that something needs to be fixed properly instead.
-
-The gudev API is no longer marked as experimental,
-G_UDEV_API_IS_SUBJECT_TO_CHANGE is no longer needed. The gudev introspection
-is enabled by default now. Various projects already depend on introspection
-information to bind dynamic languages to the gudev interfaces.
-
-udev 146
-========
-Bugfixes.
-
-The udevadm trigger "--retry-failed" option, which is replaced since quite
-a while by "--type=failed" is removed.
-
-The failed tracking was not working at all for a few releases. The RUN
-option "ignore_error" is replaced by a "fail_event_on_error" option, and the
-default is not to track any failing RUN executions.
-
-New keymaps, new modem, hid2hci updated.
-
-udev 145
-========
-Fix possible crash in udevd when worker processes are busy, rules are
-changed at the same time, and workers get killed to reload the rules.
-
-udev 144
-========
-Bugfixes.
-
-Properties set with ENV{.FOO}="bar" are marked private by starting the
-name with a '.'. They will not be stored in the database, and not be
-exported with the event.
-
-Firmware files are looked up in:
- /lib/firmware/updates/$(uname -r)
- /lib/firmware/updates
- /lib/firmware/$(uname -r)
- /lib/firmware"
-now.
-
-ATA devices switched the property from ID_BUS=scsi to ID_BUS=ata.
-ata_id, instead of scsi_id, is the default tool now for ATA devices.
-
-udev 143
-========
-Bugfixes.
-
-The configure options have changed because another library needs to be
-installed in a different location. Instead of exec_prefix and udev_prefix,
-libdir, rootlibdir and libexecdir are used. The Details are explained in
-the README file.
-
-Event processes now get re-used after they handled an event. This reduces
-the number of forks and the pressure on the CPU significantly, because
-cloned event processes no longer cause page faults in the main daemon.
-After the events have settled, a few worker processes stay around for
-future events, all others get cleaned up.
-
-To be able to use signalfd(), udev depends on kernel version 2.6.25 now.
-Also inotify support is mandatory now to run udev.
-
-The format of the queue exported by the udev damon has changed. There is
-no longer a /dev/.udev/queue/ directory. The current event queue can be
-accessed with udevadm settle and libudedv.
-
-Libudev does not have the unstable API header anymore. From now on,
-incompatible changes will be handled by bumping the library major version.
-
-To build udev from the git tree gtk-doc is needed now. The tarballs will
-build without it and contain the pre-built documentation. An online copy
-is available here:
- http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
-
-The tools from the udev-extras repository have been merged into the main
-udev repository. Some of the extras have larger external dependencies, and
-they can be disabled with the configure switch --disable-extras.
-
-udev 142
-========
-Bugfixes.
-
-The program vol_id and the library libvolume_id are removed from the
-repository. Libvolume_id is merged with libblkid from the util-linux-ng
-package. Persistent disk links for label and uuid depend on the
-util-linux-ng version (2.15) of blkid now. Older versions of blkid
-can not be used with udev.
-
-Libudev allows to subscribe to udev events. To prevent unwanted messages
-to be delivered, and waking up the subscribing process, a filter can be
-installed, to drop messages inside a kernel socket filter. The filters
-match on the <subsytem>:<devtype> properties of the device.
- This is part of the ongoing effort to replace HAL, and switch current
-users over to directly use libudev.
- Libudev is still marked as experimental, and its interface might
-eventually change if needed, but no major changes of the currently exported
-interface are expected anymore, and a first stable release should happen
-soon.
-
-A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
-is not supported since while and udevd will log an error message at
-startup. It should still be able to boot-up, but advanced rules and system
-services which depend on the information not available in the old sysfs
-format will fail to work correctly.
-
-DVB device naming is supplied by the kernel now. In case older kernels
-need to be supported, the old shell script should be added to a compat
-rules file.
-
-udev 141
-========
-Bugfixes.
-
-The processed udev events get send back to the netlink socket. Libudev
-provides access to these events. This is work-in-progress, to replace
-the DeviceKit daemon functionality directly with libudev. There are
-upcoming kernel changes to allow non-root users to subcribe to these
-events.
-
-udev 140
-========
-Bugfixes.
-
-"udevadm settle" now optionally accepts a range of events to wait for,
-instead of waiting for "all" events.
-
-udev 139
-========
-Bugfixes.
-
-The installed watch for block device metadata changes is now removed
-during event hadling, because some (broken) tools may be called from udev
-rules and (wrongly) open the device with write access. After the finished
-event handling the watch is restored.
-
-udev 138
-========
-Bugfixes.
-
-Device nodes can be watched for changes with inotify with OPTIONS="watch".
-If closed after being opened for writing, a "change" uevent will occur.
-/dev/disk/by-{label,uuid}/* symlinks will be automatically updated.
-
-udev 137
-========
-Bugfixes.
-
-The udevadm test command has no longer a --force option, nodes and symlinks
-are always updated with a test run now.
-
-The udevd daemon can be started with --resolve-names=never to avoid all user
-and group lookups (e.g. in cut-down systems) or --resolve-names=late to
-lookup user and groups every time events are handled.
-
-udev 136
-========
-Bugfixes.
-
-We are currently merging the Ubuntu rules in the udev default rules,
-and get one step closer to provide a common Linux /dev setup, regarding
-device names, symlinks, and default device permissions. On udev startup,
-we now expect the following groups to be resolvable to their ids with
-glibc's getgrnam():
- disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
-LDAP setups need to make sure, that these groups are always resolvable at
-bootup, with only the rootfs mounted, and without network access available.
-
-Some systems may need to add some new, currently not used groups, or need
-to add some users to new groups, but the cost of this change is minimal,
-compared to the pain the current, rather random, differences between the
-various distributions cause for upstream projects and third-party vendors.
-
-In general, "normal" users who log into a machine should never be a member
-of any such group, but the device-access should be managed by dynamic ACLs,
-which get added and removed for the specific users on login/logout and
-session activity/inactivity. These groups are only provided for custom setups,
-and mainly system services, to allow proper privilege separation.
-A video-streaming daemon uid would be a member of "audio" and "video", to get
-access to the sound and video devices, but no "normal" user should ever belong
-to the "audio" group, because he could listen to the built-in microphone with
-any ssh-session established from the other side of the world.
-
-/dev/serial/by-{id,path}/ now contains links for ttyUSB devices,
-which do not depend on the kernel device name. As usual, unique
-devices - only a single one per product connected, or a real
-USB serial number in the device - are always found with the same
-name in the by-id/ directory.
-Completely identical devices may overwrite their names in by-id/
-and can only be found reliably in the by-path/ directory. Devices
-specified by by-path/ must not change their connection, like the
-USB port number they are plugged in, to keep their name.
-
-To support some advanced features, Linux 2.6.22 is the oldest supported
-version now. The kernel config with enabled SYSFS_DEPRECATED is no longer
-supported. Older kernels should still work, and devices nodes should be
-reliably created, but some rules and libudev will not work correctly because
-the old kernels do not provide the expected information or interfaces.
-
-udev 135
-========
-Bugfixes.
-
-Fix for a possible segfault while swapping network interface names in udev
-versions 131-134.
-
-udev 134
-========
-Bugfixes.
-
-The group "video" is part of the default rules now.
-
-udev 133
-========
-Bugfix for kernels using SYSFS_DEPRECATED* option and finding parent
-block devices in some cases. No common distro uses this option anymore,
-and we do not get enough testing for this and recent udev versions. If
-this option is not needed to run some old distro with a new kernel,
-it should be disabled in the kernel config.
-
-Bugfix for the $links substitution variable, which may crash if no links
-are created. This should not happen in usual setups because we always
-create /dev/{block,char}/ links.
-
-The strings of the parsed rules, which are kept in memory, no longer
-contain duplicate entries, or duplicate tails of strings. This, and the
-new rules parsing/matching code reduces the total in-memory size of
-a huge distro rule sets to 0.08 MB, compared to the 1.2MB of udev
-version 130.
-
-The export of DEVTYPE=disk/partition got removed from the default
-rules. This value is available from the kernel. The pnp shell script
-modprobe hack is removed from the default rules. ACPI devices have _proper_
-modalias support and take care of the same functionality.
-Installations which support old kernels, but install current default
-udev rules may want to add that to the compat rules file.
-
-Libvolume_id now always probes for all known filesystems, and does not
-stop at the first match. Some filesystems are marked as "exclusive probe",
-and if any other filesytem type matches at the same time, libvolume_id
-will, by default, not return any probing result. This is intended to prevent
-mis-detection with conflicting left-over signatures found from earlier
-file system formats. That way, we no longer depend on the probe-order
-in case of multiple competing signatures. In some setups the kernel allows
-to mount a volume with just the old filesystem signature still in place.
-This may damage the new filesystem and cause data-loss, just by mounting
-it. Because volume_id can not decide which one the correct signature is,
-the wrong signatures need to be removed manually from the volume, or the
-volume needs to be reformatted, to enable filesystem detection and possible
-auto-mounting.
-
-udev 132
-========
-Fix segfault if compiled without optimization and dbg() does not get
-compiled out and uses variables which are not available.
-
-udev 131
-========
-Bugfixes. (And maybe new bugs. :))
-
-The rule matching engine got converted from a rule list to a token
-array which reduced the in-memory rules representation of a full
-featured distros with thousends of udev rules from 1.2MB to 0.12 MB.
-Limits like 5 ENV and ATTR matches, and one single instance for most
-other keys per rule are gone.
-
-The NAME assignment is no longer special cased. If later rules assign
-a NAME value again, the former value will be overwritten. As usual
-for most other keys, the NAME value can be protected by doing a final
-assignment with NAME:="<value>".
-
-All udev code now uses libudev, which is also exported. The library
-is still under development, marked as experimental, and its interface
-may change as long as the DeviceKit integration is not finished.
-
-Many thanks to Alan Jenkins for his continuous help, and finding and
-optimizing some of the computing expensive parts.
-
-udev 130
-========
-Bugfixes.
-
-Kernel devices and device nodes are connected now by reverse indizes in
-/sys and /dev. A device number retrieved by a stat() or similar, the
-kernel device directory can be found by looking up:
- /sys/dev/{block,char}/<maj>:<min>
-and the device node of the same device by looking up:
- /dev/{block,char}/<maj>:<min>
-
-udev 129
-========
-Fix recently introduced bug, which caused a compilation without large
-file support, where vol_id does not recognize raid signatures at the end
-of a volume.
-
-Firewire disks now create both, by-id/scsi-* and by-id/ieee-* links.
-Seems some kernel versions prevent the creation of the ieee-* links,
-so people used the scsi-* link which disappeared now.
-
-More libudev work. Almost all udevadm functionality comes from libudev
-now.
-
-udevadm trigger has a new option --type, which allows to trigger events
-for "devices", for "subsystems", or "failed" devices. The old option
---retry-failed" still works, but is no longer mentioned in the man page.
-
-udev 128
-========
-Bugfixes.
-
-The udevadm info --device-id-of-file= output has changed to use
-the obvious format. Possible current users should use the --export
-option which is not affected.
-
-The old udev commands symlinks to udevadm are not installed, if
-these symlinks are used, a warning is printed.
-
-udev 127
-========
-Bugfixes.
-
-Optical drive's media is no longer probed for raid signatures,
-reading the end of the device causes some devices to malfunction.
-Also the offset of the last session found is used now to probe
-for the filesystem.
-
-The volume_id library got a major version number update to 1,
-some deprecated functions are removed.
-
-A shared library "libudev" gets installed now to provide access
-to udev device information. DeviceKit, the successor of HAL, will
-need this library to access the udev database and search sysfs for
-devices.
-The library is currently in an experimental state, also the API is
-expected to change, as long as the DeviceKit integration is not
-finished.
-
-udev 126
-========
-We use ./configure now. See INSTALL for details. Current
-options are:
- --prefix=
- "/usr" - prefix for man pages, include files
- --exec-prefix=
- "" - the root filesystem, prefix for libs and binaries
- --sysconfdir=
- "/etc"
- --with-libdir-name=
- "lib" - directory name for libraries, not a path name
- multilib 64bit systems may use "lib64" instead of "lib"
- --enable-debug
- compile-in verbose debug messages
- --disable-logging
- disable all logging and compile-out all log strings
- --with-selinux
- link against SELInux libraries, to set the expected context
- for created files
-
-In the default rules, the group "disk" gets permissions 0660 instead
-of 0640. One small step closer to unify distro rules. Some day, all
-distros hopefully end up with the same set of rules.
-
-No symlinks to udevadm are installed anymore, if they are still needed,
-they should be provided by the package.
-
-udev 125
-========
-Bugfixes.
-
-Default udev rules, which are not supposed to be edited by the user, should
-be placed in /lib/udev/rules.d/ now, to make it clear that they are private to
-the udev package and will be replaced with an update. Udev will pick up rule
-files from:
- /lib/udev/rules.d/ - default installed rules
- /etc/udev/rules.d/ - user rules + on-the-fly generated rules
- /dev/.udev/rules.d/ - temporary non-persistent rules created after bootup
-It does not matter in which directory a rule file lives, all files are sorted
-in lexical order.
-
-To help creating /dev/root, we have now:
- $ udevadm info --export --export-prefix="ROOT_" --device-id-of-file=/
- ROOT_MAJOR=8
- ROOT_MINOR=5
-In case the current --device-id-of-file is already used, please switch to
-the --export format version, it saves the output parsing and the old
-format will be changed to use ':' as a separator, like the format in the
-sysfs 'dev' file.
-
-udev 124
-========
-Fix cdrom_id to properly recognize blank media.
-
-udev 123
-========
-Bugfixes.
-
-Tape drive id-data is queried from /dev/bsg/* instead of the tape
-nodes. This avoids rewinding tapes on open().
-
-udev 122
-========
-Bugfixes.
-
-The symlinks udevcontrol and udevtrigger are no longer installed by
-the Makefile.
-
-The scsi_id program does not depend on sysfs anymore. It can speak
-SGv4 now, so /dev/bsg/* device nodes can be used, to query SCSI device
-data, which should solve some old problems with tape devices, where
-we better do not open all tape device nodes to identify the device.
-
-udev 121
-========
-Many bugfixes.
-
-The cdrom_id program is replaced by an advanced version, which can
-detect most common device types, and also properties of the inserted
-media. This is part of moving some basic functionality from HAL into
-udev (and the kernel).
-
-udev 120
-========
-Bugfixes.
-
-The last WAIT_FOR_SYSFS rule is removed from the default rules.
-
-The symlinks to udevadm for the debugging tools: udevmonitor and
-udevtest are no longer created.
-
-The symlinks to the udevadm man page for the old tool names are
-no longer created.
-
-Abstract namespace sockets paths in RUN+="socket:@<path>" rules,
-should be prefixed with '@' to indicate that the path is not a
-real file.
-
-udev 119
-========
-Bugfixes.
-
-udev 118
-========
-Bugfixes.
-
-Udevstart is removed from the tree, it did not get installed for
-a long time now, and is long replaced by trigger and settle.
-
-udev 117
-========
-Bugfixes.
-
-All udev tools are merged into a single binary called udevadm.
-The old names of the tools are built-in commands in udevadm now.
-Symlinks to udevadm, with the names of the old tools, provide
-the same functionality as the standalone tools. There is also
-only a single udevadm.8 man page left for all tools.
-
-Tools like mkinitramfs should be checked, if they need to include
-udevadm in the list of files.
-
-udev 116
-========
-Bugfixes.
-
-udev 115
-========
-Bugfixes.
-
-The etc/udev/rules.d/ directory now contains a default set of basic
-udev rules. This initial version is the result of a rules file merge
-of Fedora and openSUSE. For these both distros only a few specific
-rules are left in their own file, named after the distro. Rules which
-are optionally installed, because they are only valid for a specific
-architecture, or rules for subsystems which are not always used are
-in etc/udev/packages/.
-
-udev 114
-========
-Bugfixes.
-
-Dynamic rules can be created in /dev/.udev/rules.d/ to trigger
-actions by dynamically created rules.
-
-SYMLINK=="<value>" matches agains the entries in the list of
-currently defined symlinks. The links are not created in the
-filesystem at that point in time, but the values can be matched.
-
-RUN{ignore_error}+="<program>" will ignore any exit code from the
-program and not record as a failed event.
-
-udev 113
-========
-Bugfixes.
-
-Final merge of patches/features from the Ubuntu package.
-
-udev 112
-========
-Bugfixes.
-
-Control characters in filesystem label strings are no longer silenty
-removed, but hex-encoded, to be able to uniquely identify the device
-by its symlink in /dev/disk/by-label/.
-If libvolume_id is used by mount(8), LABEL= will work as expected,
-if slashes or other characters are used in the label string.
-
-To test the existence of a file, TEST=="<file>" and TEST!="<file>"
-can be specified now. The TEST key accepts an optional mode mask
-TEST{0100}=="<is executable file>".
-
-Scsi_id now supports a mode without expecting scsi-specific sysfs
-entries to allow the extraction of cciss-device persistent properties.
-
-udev 111
-========
-Bugfixes.
-
-In the future, we may see uuid's which are just simple character
-strings (see the DDF Raid Specification). For that reason vol_id now
-exports ID_FS_UUID_SAFE, just like ID_FS_LABEL_SAFE. For things like
-the creation of symlinks, the *_SAFE values ensure, that no control
-or whitespace characters are used in the filename.
-
-Possible users of libvolume_id, please use the volume_id_get_* functions.
-The public struct will go away in a future release of the library.
-
-udev 110
-========
-Bugfixes.
-
-Removal of useless extras/eventrecorder.sh.
-
-udev 109
-========
-Bugfixes.
-
-udev 108
-========
-Bugfixes.
-
-The directory multiplexer for dev.d/ and hotplug.d are finally removed
-from the udev package.
-
-udev 107
-========
-Bugfixes.
-
-Symlinks can have priorities now, the priority is assigned to the device
-and specified with OPTIONS="link_priority=100". Devices with higher
-priorities overwrite the symlinks of devices with lower priorities.
-If the device that currently owns the link, goes away, the symlink
-will be removed, and recreated, pointing to the next device with the
-highest actual priority. This should make /dev/disk/by-{label,uuid,id}
-more reliable, if multiple devices contain the same metadata and overwrite
-these symlinks.
-
-The dasd_id program is removed from the udev tree, and dasdinfo, with the
-needed rules, are part of the s390-tools now.
-
-Please add KERNEL=="[0-9]*:[0-9]*" to the scsi wait-for-sysfs rule,
-we may get the scsi sysfs mess fixed some day, and this will only catch
-the devices we are looking for.
-
-USB serial numbers for storage devices have the target:lun now appended,
-to make it possibble to distinguish broken multi-lun devices with all
-the same SCSI identifiers.
-
-Note: The extra "run_directory" which searches and executes stuff in
-/etc/hotplug.d/ and /etc/dev.d/ is long deprecated, and will be removed
-with the next release. Make sure, that you don't use it anymore, or
-provides your own implementation of that inefficient stuff.
-We are tired of reports about a "slow udev", because these directories
-contain stuff, that runs with _every_ event, instead of using rules,
-that run programs only for the matching events.
-
-udev 106
-========
-Bugfixes.
-
-udev 105
-========
-Bugfixes.
-
-DRIVER== will match only for devices that actually have a real
-driver. DRIVERS== must be used, if parent devices should be
-included in the match.
-
-Libvolume_id's "linux_raid" detection needed another fix.
-
-udev 104
-========
-Bugfixes.
-
-udev 103
-========
-Add additional check to volume_id detection of via_raid, cause
-some company decided to put a matching pattern all over the empty
-storage area of their music players.
-
-udev 102
-========
-Fix path_id for SAS devices.
-
-udev 101
-========
-The udev daemon can be started with --debug-trace now, which will
-execute all events serialized to get a chance to catch a possible
-action that crashes the box.
-
-A warning is logged, if PHYSDEV* keys, the "device" link, or a parent
-device attribute like $attr{../file} is used, only WAIT_FOR_SYSFS rules
-are excluded from the warning. Referencing parent attributes directly
-may break when something in the kernel driver model changes. Udev will
-just find the attribute by walking up the parent chain.
-
-Udevtrigger now sorts the list of devices depending on the device
-dependency, so a "usb" device is triggered after the parent "pci"
-device.
-
-udev 100
-========
-Revert persistent-storage ata-serial '_' '-' replacement.
-
-udev 099
-========
-Bugfixes.
-
-Udevtrigger can now filter the list of devices to be triggered. Matches
-for subsystems or sysfs attributes can be specified.
-
-The entries in /dev/.udev/queue and /dev/.udev/failed have changed to
-zero-sized files to avoid pointing to /sys and confuse broken tools which
-scan the /dev directory. To retry failed events, udevtrigger --retry-failed
-should be used now.
-
-The rules and scripts to create udev rules for persistent network
-devices and optical drives are in the extras/rules_generator directory
-now. If you use something similar, please consider replacing your own
-version with this, to share the support effort. The rule_generator
-installs its own rules into /etc/udev/rules.d.
-
-The cdrom_id tool installs its own rule now in /etc/udev/rules.d, cause
-the rule_generator depends on cdrom_id to be called in an earlier rule.
-
-udev 098
-========
-Bugfixes.
-
-Renaming of some key names (the old names still work):
-BUS -> SUBSYSTEMS, ID -> KERNELS, SYSFS -> ATTRS, DRIVER -> DRIVERS.
-(The behavior of the key DRIVER will change soon in one of the next
-releases, to match only the event device, please switch to DRIVERS
-instead. If DRIVER is used, it will behave like DRIVERS, but an error
-is logged.
-With the new key names, we have a more consistent and simpler scheme.
-We can match the properties of the event device only, with: KERNEL,
-SUBSYSTEM, ATTR, DRIVER. Or include all the parent devices in the match,
-with: KERNELS, SUBSYSTEMS, ATTRS, DRIVERS. ID, BUS, SYSFS, DRIVER are no
-longer mentioned in the man page and should be switched in the rule
-files.
-
-ATTR{file}="value" can be used now, to write to a sysfs file of the
-event device. Instead of:
- ..., SYSFS{type}=="0|7|14", RUN+="/bin/sh -c 'echo 60 > /sys$$DEVPATH/timeout'"
-we now can do:
- ..., ATTR{type}=="0|7|14", ATTR{timeout}="60"
-
-All the PHYSDEV* keys are deprecated and will be removed from a
-future kernel:
- PHYDEVPATH - is the path of a parent device and should not be
- needed at all.
- PHYSDEVBUS - is just a SUBSYSTEM value of a parent, and can be
- matched with SUBSYSTEMS==
- PHYSDEVDRIVER - for bus devices it is available as ENV{DRIVER}.
- Newer kernels will have DRIVER in the environment,
- for older kernels udev puts in. Class device will
- no longer carry this property of a parent and
- DRIVERS== can be used to match such a parent value.
-Note that ENV{DRIVER} is only available for a few bus devices, where
-the driver is already bound at device event time. On coldplug, the
-events for a lot devices are already bound to a driver, and they will have
-that value set. But on hotplug, at the time the kernel creates the device,
-it can't know what driver may claim the device after that, therefore
-in most cases it will be empty.
-
-Failed events should now be re-triggered with:
- udevtrigger --retry-failed.
-Please switch to this command, so we keep the details of the /dev/.udev/failed/
-files private to the udev tools. We may need to switch the current symlink
-target, cause some obviously broken tools try to scan all files in /dev
-including /dev/.udev/, find the links to /sys and end up stat()'ing sysfs files
-million times. This takes ages on slow boxes.
-
-The udevinfo attribute walk (-a) now works with giving a device node
-name (-n) instead of a devpath (-p). The query now always works, also when
-no database file was created by udev.
-
-The built-in /etc/passwd /etc/group parser is removed, we always depend on
-getpwnam() and getgrnam() now. One of the next releases will depend on
-fnmatch() and may use getopt_long().
-
-udev 097
-========
-Bugfixes and small improvements.
-
-udev 096
-========
-Fix path_id for recent kernels.
-
-udev 095
-========
-%e is finally gone.
-
-Added support for swapping network interface names, by temporarily
-renaming the device and wait for the target name to become free.
-
-udev 094
-========
-The built-in MODALIAS key and substitution is removed.
-
-udev 093
-========
-The binary firmware helper is replaced by the usual simple
-shell script. Udevsend is removed from the tree.
-
-udev 092
-========
-Bugfix release.
-
-udev 091
-========
-Some more keys require the correct use of '==' and '=' depending
-on the kind of operation beeing an assignment or a match. Rules
-with invalid operations are skipped and logged to syslog. Please
-test with udevtest if the parsing of your rules throws errors and
-fix possibly broken rules.
-
-udev 090
-========
-Provide "udevsettle" to wait for all current udev events to finish.
-It also watches the current kernel netlink queue by comparing the
-even sequence number to make sure that there are no current pending
-events that have not already arrived in the daemon.
-
-udev 089
-========
-Fix rule to skip persistent rules for removable IDE devices, which
-also skipped optical IDE drives.
-
-All *_id program are installed in /lib/udev/ by default now.
-
-No binary is stripped anymore as this should be done in the
-packaging process and not at build time.
-
-libvolume_id is provided as a shared library now and vol_id is
-linked against it. Also one of the next HAL versions will require
-this library, and the HAL build process will also require the
-header file to be installed. The copy of the same code in HAL will
-be removed to have only a single copy left on the system.
-
-udev 088
-========
-Add persistent links for SCSI tapes. The rules file is renamed
-to 60-persistent-storage.rules.
-
-Create persistent path for usb devices. Can be used for all sorts
-of devices that can't be distinguished by other properties like
-multiple identical keyboards and mice connected to the same box.
-
-Provide "udevtrigger" program to request events on coldplug. The
-shell script is much too slow with thousends of devices.
-
-udev 087
-========
-Fix persistent disk rules to exclude removable IDE drives.
-
-Warn if %e, $modalias or MODALIAS is used.
-
-udev 086
-========
-Fix queue export, which wasn't correct for subsequent add/remove
-events for the same device.
-
-udev 085
-========
-Fix cramfs detection on big endian.
-
-Make WAIT_FOR_SYSFS usable in "normal" rules and silent if the whole
-device goes away.
-
-udev 084
-========
-If BUS== and SYSFS{}== have been used in the same rule, the sysfs
-attributes were only checked at the parent device that matched the
-by BUS requested subsystem. Fix it to also look at the device we
-received the event for.
-
-Build variable CROSS has changed to CROSS_COMPILE to match the kernel
-build name.
-
-udev 083
-========
-Fix a bug where NAME="" would prevent RUN from beeing executed.
-
-RUN="/bin/program" does not longer automatically add the subsystem
-as the first parameter. This is from the days of /sbin/hotplug
-which is dead now and it's just confusing to need to add a space at
-the end of the program name to prevent this.
-If you use rules that need the subsystem as the first parameter,
-like the old "udev_run_hotlugd" and "udev_run_devd", add the subsystem
-to the key like RUN+="/bin/program $env{SUBSYSTEM}".
-
-udev 082
-========
-The udev man page has moved to udev(7) as it does not describe a command
-anymore. The programs udev, udevstart and udevsend are no longer installed
-by default and must be copied manually, if they should be installed or
-included in a package.
-
-Fix a bug where "ignore_device" could run earlier collected RUN keys before
-the ignore rule was applied.
-
-More preparation for future sysfs changes. usb_id and scsi_id no longer
-depend on a magic order of devices in the /devices chain. Specific devices
-should be requested by their subsytem.
-
-This will always find the scsi parent device without depending on a specific
-path position:
- dev = sysfs_device_get(devpath);
- dev_usb = sysfs_device_get_parent_with_subsystem(dev, "scsi");
-
-The "device" link in the current sysfs layout will be automatically
-_resolved_ as a parent and in the new sysfs layout it will just _be_ the
-parent in the devpath. If a device is requested by it's symlink, like all
-class devices in the new sysfs layout will look like, it gets automatically
-resolved and substituted with the real devpath and not the symlink path.
-
-Note:
-A similar logic must be applied to _all_ sysfs users, including
-scripts, that search along parent devices in sysfs. The explicit use of
-the "device" link must be avoided. With the future sysfs layout all
-DEVPATH's will start with /devices/ and have a "subsystem" symlink poiting
-back to the "class" or the "bus". The layout of the parent devices in
-/devices is not necessarily expected to be stable across kernel releases and
-searching for parents by their subsystem should make sysfs users tolerant
-for changed parent chains.
-
-udev 081
-========
-Prepare udev to work with the experimental kernel patch, that moves
-/sys/class devices to /sys/devices and /sys/block to /sys/class/block.
-
-Clarify BUS, ID, $id usage and fix $id behavior. This prepares for
-moving the class devices to /sys/devices.
-
-Thanks again to Marco for help finding a hopefully nice compromise
-to make %b simpler and working again.
-
-udev 080
-========
-Complete removal of libsysfs, replaced by simple helper functions
-which are much simpler and a bit faster. The udev daemon operatesentirely
-on event parameters and does not use sysfs for simple rules anymore.
-Please report any new bugs/problems, that may be caused by this big
-change. They will be fixed immediately.
-
-The enumeration format character '%e' is deprecated and will be
-removed sometimes from a future udev version. It never worked correctly
-outside of udevstart, so we can't use it with the new parallel
-coldplug. A simple enumeration is as useless as the devfs naming
-scheme, just get rid of both if you still use it.
-
-MODALIAS and $modalias is not needed and will be removed from one of
-the next udev versions, replace it in all rules with ENV{MODALIAS} or
-the sysfs "modalias" value.
-
-Thanks a lot to Marco for all his help on finding and fixing bugs.
-
-udev 079
-========
-Let scsi_id request libata drive serial numbers from page 0x80.
-
-Renamed etc/udev/persistent.rules to persistent-disk.rules and
-added /dev/disk/by-name/* for device mapper device names.
-
-Removed %e from the man page. It never worked reliably outside
-of udevstart and udevstart is no longer recommended to use.
-
-udev 078
-========
-Symlinks are now exported to the event environment. Hopefully it's no
-longer needed to run udevinfo from an event process, like it was
-mentioned on the hotplug list:
- UDEV [1134776873.702967] add@/block/sdb
- ...
- DEVNAME=/dev/sdb
- DEVLINKS=/dev/disk/by-id/usb-IBM_Memory_Key_0218B301030027E8 /dev/disk/by-path/usb-0218B301030027E8:0:0:0
-
-udev 077
-========
-Fix a problem if udevsend is used as the hotplug handler and tries to use
-syslog, which causes a "vc" event loop. 2.6.15 will make udevsend obsolete
-and this kind of problems will hopefully go away soon.
-
-udev 076
-========
-All built-in logic to work around bad sysfs timing is removed with this
-version. The need to wait for sysfs files is almost fixed with a kernel
-version that doesn't work with this udev version anyway. Until we fix
-the timing of the "bus" link creation, the former integrated logic should
-be emulated by a rule placed before all other rules:
- ACTION=="add", DEVPATH=="/devices/*", ENV{PHYSDEVBUS}=="?*", WAIT_FOR_SYSFS="bus"
-
-The option "udev_db" does no longer exist. All udev state will be in
-/$udev_root/.udev/ now, there is no longer an option to set this
-to anything else.
-If the init script or something else used this value, just depend on
-this hardcoded path. But remember _all_content_ of this directory is
-still private to udev and can change at any time.
-
-Default location for rule sripts and helper programs is now: /lib/udev/.
-Everything that is not useful on the commandline should go into this
-directory. Some of the helpers in the extras folder are installed there
-now. The rules need to be changed, to find the helpers there.
-
-Also /lib/udev/devices is recommended as a directory where packages or
-the user can place real device nodes, which get copied over to /dev at
-every boot. This should replace the various solutions with custom config
-files.
-
-Udevsend does no longer start the udev daemon. This must be done with
-the init script that prepares /dev on tmpfs and creates the initial nodes,
-before starting the daemon.
-
-udev 075
-========
-Silent a too verbose error logging for the old hotplug.d/ dev.d/
-emulation.
-
-The copy of klibc is removed. A systemwide installed version of klibc
-should be used to build a klibc udev now.
-
-udev 074
-========
-NAME="" will not create any nodes, but execute RUN keys. To completely
-ignore an event the OPTION "ignore_device" should be used.
-
-After removal of the reorder queue, events with a TIMEOUT can be executed
-without any queuing now.
-
-udev 073
-========
-Fixed bug in udevd, if inotify is not available. We depend on netlink
-uevents now, kernels without that event source will not work with that
-version of udev anymore.
-
-udev 072
-========
-The rule parsing happens now in the daemon once at startup, all udev
-event processes inherit the already parsed rules from the daemon.
-It is shipped with SUSE10.0 and reduces heavily the system load at
-startup. The option to save precompiled rules and let the udev process
-pick the them up is removed, as it's no longer needed.
-
-Kernel 2.6.15 will have symlinks at /class/input pointing to the real
-device. Libsysfs is changed to "translate" the requested link into the
-real device path, as it would happen with the hotplug event. Otherwise
-device removal and the udev database will not work.
-
-Using 'make STRIPCMD=' will leave the binaries unstripped for debugging
-and packaging.
-
-A few improvements for vol_id, the filesytem probing code.
-
-udev 071
-========
-Fix a stupid typo in extras/run_directory for "make install".
-
-scsi_id creates the temporary devnode now in /dev for usage with a
-non-writable /tmp directory.
-
-The uevent kernel socket buffer can carry app. 50.000 events now,
-let's see who can break this again. :)
-
-The upcoming kernel will have a new input driver core integration.
-Some class devices are now symlinks to the real device. libsysfs
-needs a fix for this to work correctly. Udevstart of older udev
-versions will _not_ create these devices!
-
-udev 070
-========
-Fix a 'install' target in the Makefile, that prevents EXTRAS from
-beeing installed.
-
-udev 069
-========
-A bunch of mostly trivial bugfixes. From now on no node name or
-symlink name can contain any character than plain whitelisted ascii
-characters or validated utf8 byte-streams. This is needed for the
-/dev/disk/by-label/* links, because we import untrusted data and
-export it to the filesystem.
-
-udev 068
-========
-More bugfixes. If udevd was started from the kernel, we don't
-have stdin/stdout/stderr, which broke the forked tools in some
-situations.
-
-udev 067
-========
-Bugfix. udevstart event ordering was broken for a long time.
-The new run_program() uncovered it, because /dev/null was not
-available while we try to run external programs.
-Now udevstart should create it before we run anything.
-
-udev 066
-========
-Minor bugfixes and some distro rules updates. If you don't have the
-persistent disk rules in /dev/disk/by-*/* on your distro, just
-grab it from here. :)
-
-udev 065
-========
-We can use socket communication now to pass events from udev to
-other programs:
- RUN+="socket:/org/freedesktop/hal/udev_event"
-will pass the whole udev event to the HAL daemon without the need
-for a forked helper. (See ChangeLog for udevmonitor, as an example)
-
-udev 064
-========
-Mostly bugfixes and see ChangeLog.
-
-The test for the existence of an environment value should be
-switched from:
- ENV{KEY}=="*" to ENV{KEY}=="?*"
-because "*" will not fail anymore, if the key does not exist or
-is empty.
-
-udev 063
-========
-Bugfixes and a few tweaks described in the ChangeLog.
-
-udev 062
-========
-Mostly a Bugfix release.
-
-Added WAIT_FOR_SYSFS="<attribute>" to be able to fight against the sysfs
-timing with custom rules.
-
-udev 061
-========
-We changed the internal rule storage format. Our large rule files took
-2 MB of RAM, with the change we are down to 99kB.
-
-If the device-node has been created with default name and no symlink or
-options are to remenber, it is not longer stored in the udevdb. HAL will
-need to be updated to work correctly with that change.
-
-To overrride optimization flags, OPTFLAGS may be used now.
-
-udev 060
-========
-Bugfix release.
-
-udev 059
-========
-Major changes happened with this release. The goal is to take over the
-complete kernel-event handling and provide a more efficient way to dispatch
-kernel events. Replacing most of the current shell script logic and the
-kernel forked helper with a netlink-daemon and a rule-based event handling.
-
-o udevd listens to netlink events now. The first valid netlink event
- will make udevd ignore any message from udevsend that contains a
- SEQNUM, to avoid duplicate events. The forked events can be disabled
- with:
- echo "" > /proc/sys/kernel/hotplug
- For full support, the broken input-subsytem needs to be fixed, not to
- bypass the driver core.
-
-o /etc/dev.d/ + /etc/hotplug.d/ directory multiplexing is completely
- removed from udev itself and must be emulated by calling small
- helper binaries provided in the extras folder:
- make EXTRAS=extras/run_directory/
- will build udev_run_devd and udev_run_hotplugd, which can be called
- from a rule if needed:
- RUN+="/sbin/udev_run_hotplugd"
- The recommended way to handle this is to convert all the calls from
- the directories to explicit udev rules and get completely rid of the
- multiplexing. (To catch a ttyUSB event, you now no longer need to
- fork and exit 300 tty script instances you are not interested in, it
- is just one rule that matches exactly the device.)
-
-o udev handles now _all_ events not just events for class and block
- devices, this way it is possible to control the complete event
- behavior with udev rules. Especially useful for rules like:
- ACTION="add", DEVPATH="/devices/*", MODALIAS=="?*", RUN+="/sbin/modprobe $modalias"
-
-o As used in the modalias rule, udev supports now textual
- substitution placeholder along with the usual format chars. This
- needs to be documented, for now it's only visible in udev_rules_parse.c.
-
-o The rule keys support now more operations. This is documented in the
- man page. It is possible to add values to list-keys like the SYMLINK
- and RUN list with KEY+="value" and to clear the list by assigning KEY="".
- Also "final"-assignments are supported by using KEY:="value", which will
- prevent changing the key by any later rule.
-
-o kernel 2.6.12 has the "detached_state" attribute removed from
- sysfs, which was used to recognize sysfs population. We switched that
- to wait for the "bus" link, which is only available in kernels after 2.6.11.
- Running this udev version on older kernels may cause a short delay for
- some events.
-
-o To provide infrastructure for persistent device naming, the id programs:
- scsi_id, vol_id (former udev_volume_id), and ata_id (new) are able now
- to export the probed data in environment key format:
- pim:~ # /sbin/ata_id --export /dev/hda
- ID_MODEL=HTS726060M9AT00
- ID_SERIAL=MRH401M4G6UM9B
- ID_REVISION=MH4OA6BA
-
- The following rules:
- KERNEL="hd*[!0-9]", IMPORT="/sbin/ata_id --export $tempnode"
- KERNEL="hd*[!0-9]", ENV{ID_SERIAL}=="?*", SYMLINK+="disk/by-id/$env{ID_MODEL}_$env{ID_SERIAL}"
-
- Will create:
- kay@pim:~> tree /dev/disk
- /dev/disk
- |-- by-id
- | |-- HTS726060M9AT00_MRH401M4G6UM9B -> ../../hda
- | `-- IBM-Memory_Key -> ../../sda
- |-- by-label
- | |-- swap -> ../../hda1
- | |-- date -> ../../sda1
- | `-- home -> ../../hda3
- `-- by-uuid
- |-- 2E08712B0870F2E7 -> ../../hda3
- |-- 9352cfef-7687-47bc-a2a3-34cf136f72e1 -> ../../hda1
- |-- E845-7A89 -> ../../sda1
- `-- b2a61681-3812-4f13-a4ff-920d70604299 -> ../../hda2
-
- The IMPORT= operation will import these keys in the environment and make
- it available for later PROGRAM= and RUN= executed programs. The keys are
- also stored in the udevdb and can be queried from there with one of the
- next udev versions.
-
-o A few binaries are silently added to the repository, which can be used
- to replay kernel events from initramfs instead of using coldplug. udevd
- can be instructed now to queue-up events while the stored events from
- initramfs are filled into the udevd-queue. This code is still under
- development and there is no documentation now besides the code itself.
- The additional binaries get compiled, but are not installed by default.
-
-o There is also a temporary fix for a performance problem where too many
- events happen in parallel and every event needs to parse the rules.
- udev can now read precompiled rules stored on disk. This is likely to be
- replaced by a more elegant solution in a future udev version.
-
-udev 058
-========
-With kernel version 2.6.12, the sysfs file "detached_state" was removed.
-Fix for libsysfs not to expect this file was added.
-
-udev 057
-========
-All rules are applied now, but only the first matching rule with a NAME-key
-will be applied. All later rules with NAME-key are completely ignored. This
-way system supplied symlinks or permissions gets applied to user-defined
-naming rules.
-
-Note:
-Please check your rules setup, if you may need to add OPTIONS="last_rule"
-to some rules, to keep the old behavior.
-
-The rules are read on "remove"-events too. That makes is possible to match
-with keys that are available on remove (KERNEL, SUBSYSTEM, ID, ENV, ...) to
-instruct udev to ignore an event (OPTIONS="ignore_device").
-The new ACTION-key may be used to let a rule act only at a "remove"-event.
-
-The new RUN-key supports rule-based execution of programs after device-node
-handling. This is meant as a general replacement for the dev.d/-directories
-to give fine grained control over the execution of programs.
-
-The %s{}-sysfs format char replacement values are searched at any of the
-devices in the device chain now, not only at the class-device.
-
-We support log priority levels now. The value udev_log in udev.conf is used
-to determine what is printed to syslog. This makes it possible to
-run a version with compiled-in debug messages in a production environment
-which is sometimes needed to find a bug.
-It is still possible to supress the inclusion of _any_ syslog usage with
-USE_LOG=false to create the smallest possible binaries if needed.
-The configured udev_log value can be overridden with the environment variable
-UDEV_LOG.
-
-udev 056
-========
-Possible use of a system-wide klibc:
- make USE_KLIBC=true KLCC=/usr/bin/klcc all
-will link against an external klibc and our own version will be ignored.
-
-udev 055
-========
-We support an unlimited count of symlinks now.
-
-If USE_STATIC=true is passed to a glibc build, we link statically and use
-a built-in userdb parser to resolve user and group names.
-
-The PLACE= key is gone. It can be replaced by an ID= for a long time, because
-we walk up the chain of physical devices to find a match.
-
-The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
-easy to skip certain attribute matches without composing rules with weird
-character class negations like:
- KERNEL="[!s][!c][!d]*"
-this can now be replaced with:
- KERNEL!="scd*"
-The current simple '=' is still supported, and should work as it does today,
-but existing rules should be converted if possible, to be better readable.
-
-We have new ENV{}== key now, to match against a maximum of 5 environment
-variables.
-
-udevstart is its own binary again, because we don't need co carry this araound
-with every forked event.
+++ /dev/null
-udev - Linux userspace device management
-
-Integrating udev in the system has complex dependencies and may differ from
-distribution to distribution. A system may not be able to boot up or work
-reliably without a properly installed udev version. The upstream udev project
-does not recommend replacing a distro's udev installation with the upstream
-version.
-
-The upstream udev project's set of default rules may require a most recent
-kernel release to work properly.
-
-Tools and rules shipped by udev are not public API and may change at any time.
-Never call any private tool in /usr/lib/udev from any external application; it
-might just go away in the next release. Access to udev information is only offered
-by udevadm and libudev. Tools and rules in /usr/lib/udev and the entire contents
-of the /run/udev directory are private to udev and do change whenever needed.
-
-Requirements:
- - Version 2.6.34 of the Linux kernel with sysfs, procfs, signalfd, inotify,
- unix domain sockets, networking and hotplug enabled
-
- - Some architectures might need a later kernel, that supports accept4(),
- or need to backport the accept4() syscall wiring in the kernel.
-
- - These options are required:
- CONFIG_DEVTMPFS=y
- CONFIG_HOTPLUG=y
- CONFIG_INOTIFY_USER=y
- CONFIG_NET=y
- CONFIG_PROC_FS=y
- CONFIG_SIGNALFD=y
- CONFIG_SYSFS=y
- CONFIG_SYSFS_DEPRECATED*=n
- CONFIG_UEVENT_HELPER_PATH=""
-
- - These options might be needed:
- CONFIG_BLK_DEV_BSG=y (SCSI devices)
- CONFIG_TMPFS_POSIX_ACL=y (user ACLs for device nodes)
-
- - The /dev directory needs the 'devtmpfs' filesystem mounted.
- Udev only manages the permissions and ownership of the
- kernel-provided device nodes, and possibly creates additional symlinks.
-
- - Udev requires /run to be writable, which is usually done by mounting a
- 'tmpfs' filesystem.
-
- - This version of udev does not work properly with the CONFIG_SYSFS_DEPRECATED*
- option enabled.
-
- - The deprecated hotplug helper /sbin/hotplug should be disabled in the
- kernel configuration, it is not needed today, and may render the system
- unusable because the kernel may create too many processes in parallel
- so that the system runs out-of-memory.
-
- - The proc filesystem must be mounted on /proc, and the sysfs filesystem must
- be mounted at /sys. No other locations are supported by a standard
- udev installation.
-
- - The default rule sset requires the following group names resolvable at udev startup:
- disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, and kmem.
- Especially in LDAP setups, it is required that getgrnam() be able to resolve
- these group names with only the rootfs mounted and while no network is
- available.
-
- - Some udev extras have external dependencies like:
- libglib2, usbutils, pciutils, and gperf.
- All these extras can be disabled with configure options.
-
-Setup:
- - The udev daemon should be started to handle device events sent by the kernel.
- During bootup, the events for already existing devices can be replayed, so
- that they are configured by udev. The systemd service files contain the
- needed commands to start the udev daemon and the coldplug sequence.
-
- - Restarting the daemon never applies any rules to existing devices.
-
- - New/changed rule files are picked up automatically; there is usually no
- daemon restart or signal needed.
-
-Operation:
- - Based on events the kernel sends out on device creation/removal, udev
- creates/removes device nodes and symlinks in the /dev directory.
-
- - All kernel events are matched against a set of specified rules, which
- possibly hook into the event processing and load required kernel
- modules to set up devices. For all devices, the kernel exports a major/minor
- number; if needed, udev creates a device node with the default kernel
- device name. If specified, udev applies permissions/ownership to the device
- node, creates additional symlinks pointing to the node, and executes
- programs to handle the device.
-
- - The events udev handles, and the information udev merges into its device
- database, can be accessed with libudev:
- http://www.kernel.org/pub/linux/utils/kernel/hotplug/libudev/
- http://www.kernel.org/pub/linux/utils/kernel/hotplug/gudev/
-
-For more details about udev and udev rules, see the udev man pages:
- http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev/

+ * @short_description: Query devices and listen to uevents
+ *
+ * #GUdevClient is used to query information about devices on a Linux
+ * system from the Linux kernel and the udev device
+ * manager.
+ *
+ * Device information is retrieved from the kernel (through the
+ * <literal>sysfs</literal> filesystem) and the udev daemon (through a
+ * <literal>tmpfs</literal> filesystem) and presented through
+ * #GUdevDevice objects. This means that no blocking IO ever happens
+ * (in both cases, we are essentially just reading data from kernel
+ * memory) and as such there are no asynchronous versions of the
+ * provided methods.
+ *
+ * To get #GUdevDevice objects, use
+ * g_udev_client_query_by_subsystem(),
+ * g_udev_client_query_by_device_number(),
+ * g_udev_client_query_by_device_file(),
+ * g_udev_client_query_by_sysfs_path(),
+ * g_udev_client_query_by_subsystem_and_name()
+ * or the #GUdevEnumerator type.
+ *
+ * To listen to uevents, connect to the #GUdevClient::uevent signal.

+ * SECTION:gudevdevice
+ * @short_description: Get information about a device
+ *
+ * The #GUdevDevice class is used to get information about a specific
+ * device. Note that you cannot instantiate a #GUdevDevice object
+ * yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
+ * objects.
+ *
+ * To get basic information about a device, use
+ * g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
+ * g_udev_device_get_name(), g_udev_device_get_number(),
+ * g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
+ * g_udev_device_get_action(), g_udev_device_get_seqnum(),
+ * g_udev_device_get_device_type(), g_udev_device_get_device_number(),
+ * g_udev_device_get_device_file(),
+ * g_udev_device_get_device_file_symlinks().
+ *
+ * To navigate the device tree, use g_udev_device_get_parent() and
+ * g_udev_device_get_parent_with_subsystem().
+ *
+ * To access udev properties for the device, use
+ * g_udev_device_get_property_keys(),
+ * g_udev_device_has_property(),
+ * g_udev_device_get_property(),
+ * g_udev_device_get_property_as_int(),
+ * g_udev_device_get_property_as_uint64(),
+ * g_udev_device_get_property_as_double(),
+ * g_udev_device_get_property_as_boolean() and
+ * g_udev_device_get_property_as_strv().
+ *
+ * To access sysfs attributes for the device, use
+ * g_udev_device_get_sysfs_attr(),
+ * g_udev_device_get_sysfs_attr_as_int(),
+ * g_udev_device_get_sysfs_attr_as_uint64(),
+ * g_udev_device_get_sysfs_attr_as_double(),
+ * g_udev_device_get_sysfs_attr_as_boolean() and
+ * g_udev_device_get_sysfs_attr_as_strv().
+ *
+ * Note that all getters on #GUdevDevice are non-reffing – returned
+ * values are owned by the object, should not be freed and are only
+ * valid as long as the object is alive.
+ *
+ * By design, #GUdevDevice will not react to changes for a device – it
+ * only contains a snapshot of information when the #GUdevDevice
+ * object was created. To work with changes, you typically connect to
+ * the #GUdevClient::uevent signal on a #GUdevClient and get a new
+ * #GUdevDevice whenever an event happens.

+= The udev keymap tool =
+
+== Introduction ==
+
+This udev extension configures computer model specific key mappings. This is
+particularly necessary for the non-standard extra keys found on many laptops,
+such as "brightness up", "next song", "www browser", or "suspend". Often these
+are accessed with the Fn key.
+
+Every key produces a "scan code", which is highly vendor/model specific for the
+nonstandard keys. This tool maintains mappings for these scan codes to standard
+"key codes", which denote the "meaning" of the key. The key codes are defined
+in /usr/include/linux/input.h.
+
+If some of your keys on your keyboard are not working at all, or produce the
+wrong effect, then a very likely cause of this is that the scan code -> key
+code mapping is incorrect on your computer.
+
+== Structure ==
+
+udev-keymap consists of the following parts:
+
+ keymaps/*:: mappings of scan codes to key code names
+
+ 95-keymap.rules:: udev rules for mapping system vendor/product names and
+ input module names to one of the keymaps above
+
+ keymap:: manipulate an evdev input device:
+ * write a key map file into a device (used by udev rules)
+ * dump current scan → key code mapping
+ * interactively display scan and key codes of pressed keys
+
+ findkeyboards:: display evdev input devices which belong to actual keyboards,
+ i. e. those suitable for the keymap program
+
+ fdi2rules.py:: convert hal keymap FDIs into udev rules and key map files
+ (Please note that this is far from perfect, since the mapping between fdi and
+ udev rules is not straightforward, and impossible in some cases.)
+
+== Fixing broken keys ==
+
+In order to make a broken key work on your system and send it back to upstream
+for inclusion you need to do the following steps:
+
+ 1. Find the keyboard device.
+
+ Run /usr/lib/udev/findkeyboards. This should always give you an "AT
+ keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and
+ Acers) have multimedia/function keys on a separate input device instead of the
+ primary keyboard. The keyboard device should have a name like "input/event3".
+ In the following commands, the name will be written as "input/eventX" (replace
+ X with the appropriate number).
+
+ 2. Find broken scan codes:
+
+ sudo /usr/lib/udev/keymap -i input/eventX
+
+ Press all multimedia/function keys and check if the key name that gets printed
+ out is plausible. If it is unknown or wrong, write down the scan code (looks
+ like "0x1E") and the intended functionality of this key. Look in
+ /usr/include/linux/input.h for an available KEY_XXXXX constant which most
+ closely approximates this functionality and write it down as the new key code.
+
+ For example, you might press a key labeled "web browser" which currently
+ produces "unknown". Note down this:
+
+ 0x1E www # Fn+F2 web browser
+
+ Repeat that for all other keys. Write the resulting list into a file. Look at
+ /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the
+ same structure.
+
+ If the key only ever works once and then your keyboard (or the entire desktop)
+ gets stuck for a long time, then it is likely that the BIOS fails to send a
+ corresponding "key release" event after the key press event. Please note down
+ this case as well, as it can be worked around in
+ /usr/lib/udev/keymaps/95-keyboard-force-release.rules .
+
+ 3. Find out your system vendor and product:
+
+ cat /sys/class/dmi/id/sys_vendor
+ cat /sys/class/dmi/id/product_name
+
+ 4. Generate a device dump with "udevadm info --export-db > /tmp/udev-db.txt".
+
+ 6. Send the system vendor/product names, the key mapping from step 2,
+ and /tmp/udev-db.txt from step 4 to the linux-hotplug@vger.kernel.org mailing
+ list, so that they can be included in the next release.
+
+For local testing, copy your map file to /usr/lib/udev/keymaps/ with an appropriate
+name, and add an appropriate udev rule to /usr/lib/udev/rules.d/95-keymap.rules:
+
+ * If you selected an "AT keyboard", add the rule to the section after
+ 'LABEL="keyboard_vendorcheck"'.
+
+ * If you selected a "module", add the rule to the top section where the
+ "ThinkPad Extra Buttons" are.

+ * DISCLAIMER - The file format mentioned here is private to udev/libudev,
+ * and may be changed without notice.
+ *
+ * The udev event queue is exported as a binary log file.
+ * Each log record consists of a sequence number followed by the device path.
+ *
+ * When a new event is queued, its details are appended to the log.
+ * When the event finishes, a second record is appended to the log
+ * with the same sequence number but a devpath len of 0.
+ *
+ * Example:
+ * { 0x0000000000000001 }
+ * { 0x0000000000000001, 0x0019, "/devices/virtual/mem/null" },
+ * { 0x0000000000000002, 0x001b, "/devices/virtual/mem/random" },
+ * { 0x0000000000000001, 0x0000 },
+ * { 0x0000000000000003, 0x0019, "/devices/virtual/mem/zero" },
+ *
+ * Events 2 and 3 are still queued, but event 1 has finished.
+ *
+ * The queue does not grow indefinitely. It is periodically re-created
+ * to remove finished events. Atomic rename() makes this transparent to readers.
+ *
+ * The queue file starts with a single sequence number which specifies the
+ * minimum sequence number in the log that follows. Any events prior to this
+ * sequence number have already finished.

-# Ok, we probably need a little explanation here for what the two lines above
-# are good for.
-#
-# The story goes like this: when ALSA registers a new sound card it emits a
-# series of 'add' events to userspace, for the main card device and for all the
-# child device nodes that belong to it. udev relays those to applications,
-# however only maintains the order between father and child, but not between
-# the siblings. The control device node creation can be used as synchronization
-# point. All other devices that belong to a card are created in the kernel
-# before it. However unfortunately due to the fact that siblings are forwarded
-# out of order by udev this fact is lost to applications.
-#
-# OTOH before an application can open a device it needs to make sure that all
-# its device nodes are completely created and set up.
-#
-# As a workaround for this issue we have added the udev rule above which will
-# generate a 'change' event on the main card device from the 'add' event of the
-# card's control device. Due to the ordering semantics of udev this event will
-# only be relayed after all child devices have finished processing properly.
-# When an application needs to listen for appearing devices it can hence look
-# for 'change' events only, and ignore the actual 'add' events.
-#
-# When the application is initialized at the same time as a device is plugged
-# in it may need to figure out if the 'change' event has already been triggered
-# or not for a card. To find that out we store the flag environment variable
-# SOUND_INITIALIZED on the device which simply tells us if the card 'change'
-# event has already been processed.

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-\f
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-\f
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-\f
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-\f
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-\f
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-\f
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-\f
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- How to Apply These Terms to Your New Libraries
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
- To apply these terms, attach the following notices to the library. It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
- <one line to give the library's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This library is free software; you can redistribute it and/or
- modify it under the terms of the GNU Lesser General Public
- License as published by the Free Software Foundation; either
- version 2.1 of the License, or (at your option) any later version.
-
- This library is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU

- License along with this library; if not, write to the Free Software
- Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the

- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-not price. Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-\f
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-\f
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-\f
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-\f
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-\f
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-\f
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-\f
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-\f
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- How to Apply These Terms to Your New Libraries
-
- If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change. You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
- To apply these terms, attach the following notices to the library. It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
- <one line to give the library's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- This library is free software; you can redistribute it and/or
- modify it under the terms of the GNU Lesser General Public
- License as published by the Free Software Foundation; either
- version 2.1 of the License, or (at your option) any later version.
-
- This library is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
- Lesser General Public License for more details.
-
- You should have received a copy of the GNU Lesser General Public
- License along with this library; if not, write to the Free Software
- Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the

- * SECTION:gudevclient
- * @short_description: Query devices and listen to uevents
- *
- * #GUdevClient is used to query information about devices on a Linux
- * system from the Linux kernel and the udev device
- * manager.
- *
- * Device information is retrieved from the kernel (through the
- * <literal>sysfs</literal> filesystem) and the udev daemon (through a
- * <literal>tmpfs</literal> filesystem) and presented through
- * #GUdevDevice objects. This means that no blocking IO ever happens
- * (in both cases, we are essentially just reading data from kernel
- * memory) and as such there are no asynchronous versions of the
- * provided methods.
- *
- * To get #GUdevDevice objects, use
- * g_udev_client_query_by_subsystem(),
- * g_udev_client_query_by_device_number(),
- * g_udev_client_query_by_device_file(),
- * g_udev_client_query_by_sysfs_path(),
- * g_udev_client_query_by_subsystem_and_name()
- * or the #GUdevEnumerator type.
- *
- * To listen to uevents, connect to the #GUdevClient::uevent signal.

-/**
- * SECTION:gudevdevice
- * @short_description: Get information about a device
- *
- * The #GUdevDevice class is used to get information about a specific
- * device. Note that you cannot instantiate a #GUdevDevice object
- * yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
- * objects.
- *
- * To get basic information about a device, use
- * g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
- * g_udev_device_get_name(), g_udev_device_get_number(),
- * g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
- * g_udev_device_get_action(), g_udev_device_get_seqnum(),
- * g_udev_device_get_device_type(), g_udev_device_get_device_number(),
- * g_udev_device_get_device_file(),
- * g_udev_device_get_device_file_symlinks().
- *
- * To navigate the device tree, use g_udev_device_get_parent() and
- * g_udev_device_get_parent_with_subsystem().
- *
- * To access udev properties for the device, use
- * g_udev_device_get_property_keys(),
- * g_udev_device_has_property(),
- * g_udev_device_get_property(),
- * g_udev_device_get_property_as_int(),
- * g_udev_device_get_property_as_uint64(),
- * g_udev_device_get_property_as_double(),
- * g_udev_device_get_property_as_boolean() and
- * g_udev_device_get_property_as_strv().
- *
- * To access sysfs attributes for the device, use
- * g_udev_device_get_sysfs_attr(),
- * g_udev_device_get_sysfs_attr_as_int(),
- * g_udev_device_get_sysfs_attr_as_uint64(),
- * g_udev_device_get_sysfs_attr_as_double(),
- * g_udev_device_get_sysfs_attr_as_boolean() and
- * g_udev_device_get_sysfs_attr_as_strv().
- *
- * Note that all getters on #GUdevDevice are non-reffing – returned
- * values are owned by the object, should not be freed and are only
- * valid as long as the object is alive.
- *
- * By design, #GUdevDevice will not react to changes for a device – it
- * only contains a snapshot of information when the #GUdevDevice
- * object was created. To work with changes, you typically connect to
- * the #GUdevClient::uevent signal on a #GUdevClient and get a new
- * #GUdevDevice whenever an event happens.

-= The udev keymap tool =
-
-== Introduction ==
-
-This udev extension configures computer model specific key mappings. This is
-particularly necessary for the non-standard extra keys found on many laptops,
-such as "brightness up", "next song", "www browser", or "suspend". Often these
-are accessed with the Fn key.
-
-Every key produces a "scan code", which is highly vendor/model specific for the
-nonstandard keys. This tool maintains mappings for these scan codes to standard
-"key codes", which denote the "meaning" of the key. The key codes are defined
-in /usr/include/linux/input.h.
-
-If some of your keys on your keyboard are not working at all, or produce the
-wrong effect, then a very likely cause of this is that the scan code -> key
-code mapping is incorrect on your computer.
-
-== Structure ==
-
-udev-keymap consists of the following parts:
-
- keymaps/*:: mappings of scan codes to key code names
-
- 95-keymap.rules:: udev rules for mapping system vendor/product names and
- input module names to one of the keymaps above
-
- keymap:: manipulate an evdev input device:
- * write a key map file into a device (used by udev rules)
- * dump current scan → key code mapping
- * interactively display scan and key codes of pressed keys
-
- findkeyboards:: display evdev input devices which belong to actual keyboards,
- i. e. those suitable for the keymap program
-
- fdi2rules.py:: convert hal keymap FDIs into udev rules and key map files
- (Please note that this is far from perfect, since the mapping between fdi and
- udev rules is not straightforward, and impossible in some cases.)
-
-== Fixing broken keys ==
-
-In order to make a broken key work on your system and send it back to upstream
-for inclusion you need to do the following steps:
-
- 1. Find the keyboard device.
-
- Run /usr/lib/udev/findkeyboards. This should always give you an "AT
- keyboard" and possibly a "module". Some laptops (notably Thinkpads, Sonys, and
- Acers) have multimedia/function keys on a separate input device instead of the
- primary keyboard. The keyboard device should have a name like "input/event3".
- In the following commands, the name will be written as "input/eventX" (replace
- X with the appropriate number).
-
- 2. Find broken scan codes:
-
- sudo /usr/lib/udev/keymap -i input/eventX
-
- Press all multimedia/function keys and check if the key name that gets printed
- out is plausible. If it is unknown or wrong, write down the scan code (looks
- like "0x1E") and the intended functionality of this key. Look in
- /usr/include/linux/input.h for an available KEY_XXXXX constant which most
- closely approximates this functionality and write it down as the new key code.
-
- For example, you might press a key labeled "web browser" which currently
- produces "unknown". Note down this:
-
- 0x1E www # Fn+F2 web browser
-
- Repeat that for all other keys. Write the resulting list into a file. Look at
- /usr/lib/udev/keymaps/ for existing key map files and make sure that you use the
- same structure.
-
- If the key only ever works once and then your keyboard (or the entire desktop)
- gets stuck for a long time, then it is likely that the BIOS fails to send a
- corresponding "key release" event after the key press event. Please note down
- this case as well, as it can be worked around in
- /usr/lib/udev/keymaps/95-keyboard-force-release.rules .
-
- 3. Find out your system vendor and product:
-
- cat /sys/class/dmi/id/sys_vendor
- cat /sys/class/dmi/id/product_name
-
- 4. Generate a device dump with "udevadm info --export-db > /tmp/udev-db.txt".
-
- 6. Send the system vendor/product names, the key mapping from step 2,
- and /tmp/udev-db.txt from step 4 to the linux-hotplug@vger.kernel.org mailing
- list, so that they can be included in the next release.
-
-For local testing, copy your map file to /usr/lib/udev/keymaps/ with an appropriate
-name, and add an appropriate udev rule to /usr/lib/udev/rules.d/95-keymap.rules:
-
- * If you selected an "AT keyboard", add the rule to the section after
- 'LABEL="keyboard_vendorcheck"'.
-
- * If you selected a "module", add the rule to the top section where the
- "ThinkPad Extra Buttons" are.

- * DISCLAIMER - The file format mentioned here is private to udev/libudev,
- * and may be changed without notice.
- *
- * The udev event queue is exported as a binary log file.
- * Each log record consists of a sequence number followed by the device path.
- *
- * When a new event is queued, its details are appended to the log.
- * When the event finishes, a second record is appended to the log
- * with the same sequence number but a devpath len of 0.
- *
- * Example:
- * { 0x0000000000000001 }
- * { 0x0000000000000001, 0x0019, "/devices/virtual/mem/null" },
- * { 0x0000000000000002, 0x001b, "/devices/virtual/mem/random" },
- * { 0x0000000000000001, 0x0000 },
- * { 0x0000000000000003, 0x0019, "/devices/virtual/mem/zero" },
- *
- * Events 2 and 3 are still queued, but event 1 has finished.
- *
- * The queue does not grow indefinitely. It is periodically re-created
- * to remove finished events. Atomic rename() makes this transparent to readers.
- *
- * The queue file starts with a single sequence number which specifies the
- * minimum sequence number in the log that follows. Any events prior to this
- * sequence number have already finished.

-.TH SCSI_ID 8 "December 2003" "" "Linux Administrator's Manual"
-.SH NAME
-scsi_id \- retrieve and generate a unique SCSI identifier
-.SH SYNOPSIS
-.BI scsi_id
-[\fIoptions\fP]
-.SH "DESCRIPTION"
-.B scsi_id
-queries a SCSI device via the SCSI INQUIRY vital product data (VPD) page 0x80 or
-0x83 and uses the resulting data to generate a value that is unique across
-all SCSI devices that properly support page 0x80 or page 0x83.
-
-If a result is generated it is sent to standard output, and the program
-exits with a zero value. If no identifier is output, the program exits
-with a non\-zero value.
-
-\fBscsi_id\fP is primarily for use by other utilities such as \fBudev\fP
-that require a unique SCSI identifier.
-
-By default all devices are assumed black listed, the \fB\-\-whitelisted\fP option must
-be specified on the command line or in the config file for any useful
-behaviour.
-
-SCSI commands are sent directly to the device via the SG_IO ioctl
-interface.
-
-In order to generate unique values for either page 0x80 or page 0x83, the
-serial numbers or world wide names are prefixed as follows.
-
-Identifiers based on page 0x80 are prefixed by the character 'S', the SCSI
-vendor, the SCSI product (model) and then the the serial number returned
-by page 0x80. For example:
-
-.sp

-The default behaviour \- treat the device as black listed, and do nothing
-unless a white listed device is found in the scsi_id config\-file.
-.TP

-Send SG_IO commands to \fBdevice\fP, such as \fB/dev/sdc\fP.

-Read configuration and black/white list entries from
-.B config\-file
-rather than the default

-file.
-.TP
-.BI \-\-whitelisted
-Treat the device as white listed. The \fB\-\-whitelisted\fP option must be specified
-on the command line or in the scsi_id configuration file for
-.B scsi_id
-to generate any output.
-.TP
-.BI \-\-page=\| 0x80 | 0x83 | pre-spc3-83
-Use SCSI INQUIRY VPD page code 0x80, 0x83, or pre-spc3-83.
-.sp
-The default
-behaviour is to query the available VPD pages, and use page 0x83 if found,
-else page 0x80 if found, else nothing.
-.sp
-Page pre-spc3-83 should only be utilized for those scsi devices which
-are not compliant with the SPC-2 or SPC-3 format for page 83. While this
-option is used for older model 4, 5, and 6 EMC Symmetrix devices, its
-use with SPC-2 or SPC-3 compliant devices will fallback to the page 83
-format supported by these devices.

- Reference implementation of a few systemd related interfaces for
- writing daemons. These interfaces are trivial to implement. To
- simplify porting we provide this reference implementation.
- Applications are welcome to reimplement the algorithms described
- here if they do not want to include these two source files.
-
- The following functionality is provided:
-
- - Support for logging with log levels on stderr
- - File descriptor passing for socket-based activation
- - Daemon startup and status notification
- - Detection of systemd boots
-
- You may compile this with -DDISABLE_SYSTEMD to disable systemd
- support. This makes all those calls NOPs that are directly related to
- systemd (i.e. only sd_is_xxx() will stay useful).
-
- Since this is drop-in code we don't want any of our symbols to be
- exported in any case. Hence we declare hidden visibility for all of
- them.
-
- You may find an up-to-date version of these source files online:
-
- http://cgit.freedesktop.org/systemd/systemd/plain/src/systemd/sd-daemon.h
- http://cgit.freedesktop.org/systemd/systemd/plain/src/sd-daemon.c
-
- This should compile on non-Linux systems, too, but with the
- exception of the sd_is_xxx() calls all functions will become NOPs.
-
- See sd-daemon(7) for more information.

- Informs systemd about changed daemon state. This takes a number of
- newline separated environment-style variable assignments in a
- string. The following variables are known:
-
- READY=1 Tells systemd that daemon startup is finished (only
- relevant for services of Type=notify). The passed
- argument is a boolean "1" or "0". Since there is
- little value in signaling non-readiness the only
- value daemons should send is "READY=1".
-
- STATUS=... Passes a single-line status string back to systemd
- that describes the daemon state. This is free-from
- and can be used for various purposes: general state
- feedback, fsck-like programs could pass completion
- percentages and failing programs could pass a human
- readable error message. Example: "STATUS=Completed
- 66% of file system check..."
-
- ERRNO=... If a daemon fails, the errno-style error code,
- formatted as string. Example: "ERRNO=2" for ENOENT.
-
- BUSERROR=... If a daemon fails, the D-Bus error-style error
- code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut"
-
- MAINPID=... The main pid of a daemon, in case systemd did not
- fork off the process itself. Example: "MAINPID=4711"
-
- WATCHDOG=1 Tells systemd to update the watchdog timestamp.
- Services using this feature should do this in
- regular intervals. A watchdog framework can use the
- timestamps to detect failed services.
-
- Daemons can choose to send additional variables. However, it is
- recommended to prefix variable names not listed above with X_.
-
- Returns a negative errno-style error code on failure. Returns > 0
- if systemd could be notified, 0 if it couldn't possibly because
- systemd is not running.
-
- Example: When a daemon finished starting up, it could issue this
- call to notify systemd about it:

- sd_notify(0, "READY=1");

- See sd_notifyf() for more complete examples.

- <refsect1><title>Description</title>
- <para>udev supplies the system software with device events, manages permissions
- of device nodes and may create additional symlinks in the <filename>/dev</filename>
- directory, or renames network interfaces. The kernel usually just assigns unpredictable
- device names based on the order of discovery. Meaningful symlinks or network device
- names provide a way to reliably identify devices based on their properties or
- current configuration.</para>
-
- <para>The udev daemon, <citerefentry><refentrytitle>udevd</refentrytitle>
- <manvolnum>8</manvolnum></citerefentry>, receives device uevents directly from
- the kernel whenever a device is added or removed from the system, or it changes its
- state. When udev receives a device event, it matches its configured set of rules
- against various device attributes to identify the device. Rules that match may
- provide additional device information to be stored in the udev database or
- to be used to create meaningful symlink names.</para>
-
- <para>All device information udev processes is stored in the udev database and
- sent out to possible event subscribers. Access to all stored data and the event
- sources is provided by the library libudev.</para>
- </refsect1>
-
- <refsect1><title>Configuration</title>
- <para>udev configuration files are placed in <filename>/etc/udev</filename>
- and <filename>/usr/lib/udev</filename>. All empty lines or lines beginning with
- '#' are ignored.</para>
-
- <refsect2><title>Configuration file</title>
- <para>udev expects its main configuration file at <filename>/etc/udev/udev.conf</filename>.
- It consists of a set of variables allowing the user to override default udev values.
- The following variables can be set:</para>
- <variablelist>
- <varlistentry>
- <term><option>udev_root</option></term>
- <listitem>
- <para>Specifies where to place the device nodes in the filesystem.
- The default value is <filename>/dev</filename>.</para>
- </listitem>
- </varlistentry>
-
- <varlistentry>
- <term><option>udev_log</option></term>
- <listitem>
- <para>The logging priority. Valid values are the numerical syslog priorities
- or their textual representations: <option>err</option>, <option>info</option>
- and <option>debug</option>.</para>
- </listitem>
- </varlistentry>
- </variablelist>
- </refsect2>
-
- <refsect2><title>Rules files</title>
- <para>The udev rules are read from the files located in the
- system rules directory <filename>/usr/lib/udev/rules.d</filename>,
- the volatile runtime directory <filename>/run/udev/rules.d</filename>
- and the local administration directory <filename>/etc/udev/rules.d</filename>.
- All rules files are collectively sorted and processed in lexical order,
- regardless of the directories in which they live. However, files with
- identical file names replace each other. Files in <filename>/etc</filename>
- have the highest priority, files in <filename>/run</filename> take precedence
- over files with the same name in <filename>/lib</filename>. This can be
- used to override a system-supplied rules file with a local file if needed;
- a symlink in <filename>/etc</filename> with the same name as a rules file in
- <filename>/lib</filename>, pointing to <filename>/dev/null</filename>,
- disables the rules file entirely.</para>
