Cgroup v2 device controller has no interface files and is implemented
on top of cgroup BPF. To control access to device files, a user may
-create bpf programs of the BPF_CGROUP_DEVICE type and attach them
-to cgroups. On an attempt to access a device file, corresponding
-BPF programs will be executed, and depending on the return value
-the attempt will succeed or fail with -EPERM.
-
-A BPF_CGROUP_DEVICE program takes a pointer to the bpf_cgroup_dev_ctx
-structure, which describes the device access attempt: access type
-(mknod/read/write) and device (type, major and minor numbers).
-If the program returns 0, the attempt fails with -EPERM, otherwise
-it succeeds.
-
-An example of BPF_CGROUP_DEVICE program may be found in the kernel
-source tree in the tools/testing/selftests/bpf/progs/dev_cgroup.c file.

NTFS3
=====

Summary and Features
====================
-NTFS3 is fully functional NTFS Read-Write driver. The driver works with
-NTFS versions up to 3.1, normal/compressed/sparse files
-and journal replaying. File system type to use on mount is 'ntfs3'.
+NTFS3 is fully functional NTFS Read-Write driver. The driver works with NTFS
+versions up to 3.1. File system type to use on mount is *ntfs3*.
- This driver implements NTFS read/write support for normal, sparse and
compressed files.
-- Supports native journal replaying;
-- Supports extended attributes
- Predefined extended attributes:
- - 'system.ntfs_security' gets/sets security
- descriptor (SECURITY_DESCRIPTOR_RELATIVE)
- - 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.
- Note: applied to empty files, this allows to switch type between
- sparse(0x200), compressed(0x800) and normal;
+- Supports native journal replaying.
- Supports NFS export of mounted NTFS volumes.
+- Supports extended attributes. Predefined extended attributes:
+
+ - *system.ntfs_security* gets/sets security
+
+ Descriptor: SECURITY_DESCRIPTOR_RELATIVE
+
+ - *system.ntfs_attrib* gets/sets ntfs file/dir attributes.
+
+ Note: Applied to empty files, this allows to switch type between
+ sparse(0x200), compressed(0x800) and normal.
Mount Options
=============
The list below describes mount options supported by NTFS3 driver in addition to
-generic ones.
+generic ones. You can use every mount option with **no** option. If it is in
+this table marked with no it means default is without **no**.
-===============================================================================
+.. flat-table::
+ :widths: 1 5
+ :fill-cells:
-nls=name This option informs the driver how to interpret path
- strings and translate them to Unicode and back. If
- this option is not set, the default codepage will be
- used (CONFIG_NLS_DEFAULT).
- Examples:
- 'nls=utf8'
+ * - iocharset=name
+ - This option informs the driver how to interpret path strings and
+ translate them to Unicode and back. If this option is not set, the
+ default codepage will be used (CONFIG_NLS_DEFAULT).
-uid=
-gid=
-umask= Controls the default permissions for files/directories created
- after the NTFS volume is mounted.
+ Example: iocharset=utf8
-fmask=
-dmask= Instead of specifying umask which applies both to
- files and directories, fmask applies only to files and
- dmask only to directories.
+ * - uid=
+ - :rspan:`1`
+ * - gid=
-nohidden Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)
- attribute will not be shown under Linux.
+ * - umask=
+ - Controls the default permissions for files/directories created after
+ the NTFS volume is mounted.
-sys_immutable Files with the Windows-specific SYSTEM
- (FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system
- immutable files.
+ * - dmask=
+ - :rspan:`1` Instead of specifying umask which applies both to files and
+ directories, fmask applies only to files and dmask only to directories.
+ * - fmask=
-discard Enable support of the TRIM command for improved performance
- on delete operations, which is recommended for use with the
- solid-state drives (SSD).
+ * - noacsrules
+ - "No access rules" mount option sets access rights for files/folders to
+ 777 and owner/group to root. This mount option absorbs all other
+ permissions.
-force Forces the driver to mount partitions even if 'dirty' flag
- (volume dirty) is set. Not recommended for use.
+ - Permissions change for files/folders will be reported as successful,
+ but they will remain 777.
-sparse Create new files as "sparse".
+ - Owner/group change will be reported as successful, butthey will stay
+ as root.
-showmeta Use this parameter to show all meta-files (System Files) on
- a mounted NTFS partition.
- By default, all meta-files are hidden.
+ * - nohidden
+ - Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute
+ will not be shown under Linux.
-prealloc Preallocate space for files excessively when file size is
- increasing on writes. Decreases fragmentation in case of
- parallel write operations to different files.
+ * - sys_immutable
+ - Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute
+ will be marked as system immutable files.
-no_acs_rules "No access rules" mount option sets access rights for
- files/folders to 777 and owner/group to root. This mount
- option absorbs all other permissions:
- - permissions change for files/folders will be reported
- as successful, but they will remain 777;
- - owner/group change will be reported as successful, but
- they will stay as root
+ * - discard
+ - Enable support of the TRIM command for improved performance on delete
+ operations, which is recommended for use with the solid-state drives
+ (SSD).
-acl Support POSIX ACLs (Access Control Lists). Effective if
- supported by Kernel. Not to be confused with NTFS ACLs.
- The option specified as acl enables support for POSIX ACLs.
+ * - force
+ - Forces the driver to mount partitions even if volume is marked dirty.
+ Not recommended for use.
-noatime All files and directories will not update their last access
- time attribute if a partition is mounted with this parameter.
- This option can speed up file system operation.
+ * - sparse
+ - Create new files as sparse.
-===============================================================================
+ * - showmeta
+ - Use this parameter to show all meta-files (System Files) on a mounted
+ NTFS partition. By default, all meta-files are hidden.
-ToDo list
-=========
+ * - prealloc
+ - Preallocate space for files excessively when file size is increasing on
+ writes. Decreases fragmentation in case of parallel write operations to
+ different files.
-- Full journaling support (currently journal replaying is supported) over JBD.
+ * - acl
+ - Support POSIX ACLs (Access Control Lists). Effective if supported by
+ Kernel. Not to be confused with NTFS ACLs. The option specified as acl
+ enables support for POSIX ACLs.
+Todo list
+=========
+- Full journaling support over JBD. Currently journal replaying is supported
+ which is not necessarily as effectice as JBD would be.
