9 | ||
10 | * : Tag zfs-0.4.9 - Use 'git log --no-merges' for full change log. | |
11 | ||
12 | * : Build system improvements: | |
13 | - Added support for the 'make -s' silent build option. | |
14 | - Allow zfs_config.h to be included by dependent packages. | |
15 | - Minor spec file updates. | |
16 | - Minor build system message updates. | |
17 | ||
18 | * : Topic branch cleanup. Several old branches were removed and | |
19 | numerous hunks which were accidentaly commited to incorrect topic | |
20 | branches in the past were relocated to the correct topic branch. | |
21 | ||
22 | * *.c, *.h, *.sh, AUTHORS, COPYING, COPYRIGHT, DISCLAIMER, README: | |
23 | Added standard header to source files which includes the copyright, | |
24 | license, and author information. Additionally, updated the listed | |
25 | top level files to the latest versions. | |
26 | ||
27 | * cmd/zpool/zpool_vdev.c: Check all partitions with check_file() | |
28 | even when no libblkid is found. This oversight would result in | |
29 | ZFS not detecting existing filesystems on partitions. | |
30 | ||
31 | * module/zfs/fm.c, module/zfs/zfs_fm, libzfs/libzfs_pool.c: | |
32 | Added zevents which are similar to Solaris FMA support. The | |
33 | existing FMA and sysevent call points in ZFS were unified in | |
34 | to a single event type and used to create a user space visible | |
35 | event notification system under Linux. The new 'zpool events' | |
36 | command can be used to show all recent ZFS events. | |
37 | ||
38 | * module/zfs/spa.c, module/zfs/zil.c: Suppress large memory | |
39 | allocation warnings for two particular kmem_alloc()'s. For | |
40 | now we can live with them as is but long term a way should be | |
41 | found to perform small allocations or use the vmem based slab. | |
42 | ||
43 | * module/zfs/zvol.c: Recreate volume and snapshot /dev links during | |
44 | module load. Links in /dev for volumes/snapshots were only being | |
45 | created at volume/snapshot creation time. Those links are now also | |
46 | created dynamically at module load time based on the spa config. | |
47 | ||
48 | * module/zfs/zvol.c, module/zfs/include/sys/blkdev.h: The handler | |
49 | zvol_request() should use the unlocked version of blk_end_request() | |
50 | to avoid a deadlock in the ZVOL. | |
51 | ||
52 | 2010-03-11 Brian Behlendorf <behlendorf1@llnl.gov> | |
53 | ||
54 | * : Tag zfs-0.4.8 - Use 'git log --no-merges' for full change log. | |
55 | ||
56 | * : Build system improvements: | |
57 | - Remove Module.markers and Module.symver{s} in clean target. | |
58 | - Improved kernel source detection when none specified. | |
59 | - Fix RPM definitions for the unknown distro/installation. | |
60 | - Check for spl in ../spl if not found in install path. | |
61 | - Include all headers regardless of depth in packages. | |
62 | - Allow recursive configure/make. | |
63 | ||
64 | * lib/libzpool/kernel.c: Fixed several zdb bugs when opening a pool | |
65 | - zdb wasn't getting the correct device size when the vdev is a | |
66 | block device. In Solaris, fstat64() returns the device size but | |
67 | in Linux an ioctl() is needed. | |
68 | - make sure that we don't try to open a block device in write mode | |
69 | from userspace. This shouldn't happen, because zdb opens devices | |
70 | in read-only mode, and ztest only uses files. | |
71 | ||
72 | * lib/libspl/include/umem.h: Add umem_alloc_aligned() and honor | |
73 | cache_align field for umem cache. Under linux we open block devices | |
74 | with O_DIRECT which means we must provide aligned memory buffers. | |
75 | ||
76 | * lib/libzpool/kernel.c: Fix some incorrect error handling. In | |
77 | vn_open(), if fstat64() returned an error, the real errno was being | |
78 | obscured by calling close(). | |
79 | ||
80 | * scripts/*: Fix scripts to work when invoked from other directories. | |
81 | ||
82 | * module/zfs/arc.c: Fix struct ht_lock padding in arc.c. | |
83 | ||
84 | * lib/libefi/include/sys/uuid.h: Fix duplicate uuid_t typedef. | |
85 | ||
86 | * module/zfs/txg.c: Use CPU percentages for number of commit cb | |
87 | threads. This doesn't change number of threads in the kernel, but it | |
88 | reduces number of threads in ztest (important due to 32-bit address | |
89 | limitations). | |
90 | ||
91 | * cmd/ztest/ztest.c: Clean up emulation of kernel threads in | |
92 | userspace. Updated to use pthread thread specific data rather than | |
93 | keeping a global list. This also fixes at least one easily | |
94 | reproducible crash in ztest | |
95 | ||
96 | * META, config/kernel.m4: Add configure check for kernel build | |
97 | options which are incompatible with the license. If your building | |
98 | against a kernel deemed incompatible configure will fail and | |
99 | suggest how you should rebuild your kernel. | |
100 | ||
101 | * config/kernel-fmode-t.m4: Linux 2.6.28 compat, add a check for the | |
102 | fmode_t type. This typedef first appears in 2.6.28 kernels as part | |
103 | of some block device operation reworking. | |
104 | ||
105 | * module/zfs/dmu_send.c: No inline to keep dmu_recv_stream() stack | |
106 | frame less than 1024 bytes. Recent builds against 2.6.31 flagged | |
107 | dmu_recv_stream() as stack heavy. Further analysis of this function | |
108 | should be performed to further reduce its stack usage. | |
109 | ||
110 | * scripts/common.sh: Split the udev rule from a specific configuration | |
111 | by providing a generic 60-zpool.rules file which uses a small helper | |
112 | util 'zpool_id' to parse a configuration file by default located in | |
113 | /etc/zfs/zdev.conf. The helper script maps a by-path udev name to a | |
114 | more friendly name of <channel><rank> for large configurations. | |
115 | ||
116 | Additionally, when running zpool-create.sh in-tree it will no longer | |
117 | use udev because we would have to copy certain helper scripts in to | |
118 | the installed system. To avoid this the config file in simply | |
119 | parsed and symlinks are created in your working tree. The script | |
120 | will use udev if it as run as part of an installed zfs-test package. | |
121 | ||
122 | * module/zfs/zvol.c: Use check_disk_change() instead of | |
123 | revalidate_disk(). For 2.6.27 kernels are earlier revalidate_disk() | |
124 | was not available. However, check_disk_change() has been available | |
125 | for far longer and will properly inform the kernel of the volume | |
126 | change for both older and newer kernels. | |
127 | ||
128 | * module/zfs/dmu.c: Fixed incorrect ASSERT3S() added by ZVOL. | |
129 | ||
130 | * module/zfs/vdev_raidz.c, module/zfs/zvol.c: Minor fixes for 32-bit. | |
131 | ||
132 | * scripts/zfs-update.sh, man/man8/*: Added man pages based on the | |
133 | latest documentation and modified zfs-update.sh script to update them. | |
134 | ||
135 | * .gitignore: Updated .gitignore rules to exclude build products. | |
136 | ||
137 | 2009-11-24 Brian Behlendorf <behlendorf1@llnl.gov> | |
138 | ||
139 | * : Tag zfs-0.4.7 - Use 'git log --no-merges' for full change log. | |
140 | ||
141 | * module/zcommon/include/sys/fs/zfs.h, module/zfs/include/sys/blkdev.h, | |
142 | module/zfs/include/sys/dmu.h, module/zfs/dmu.c, | |
143 | module/zfs/include/sys/zvol.h, module/zfs/zvol.c, | |
144 | module/zfs/zfs_ioctl.c: | |
145 | Added the ZVOL block device, with the addition of the ZVOL real ZFS | |
146 | based block devices are available and can be compared head to head | |
147 | with Linux's MD and LVM block drivers. The Linux ZVOL has not yet | |
148 | had any performance work done but from a user perspective it should | |
149 | be functionally complete and behave like any other Linux block device. | |
150 | The ZVOL has so far been tested using zconfig.sh on the following | |
151 | x86_64 based platforms: FC11, CHAOS4, RHEL5, RHEL6, and SLES11. | |
152 | However, more testing is required to ensure everything is working | |
153 | as designed. | |
154 | ||
155 | * scripts/udev-rules/99-zpool.rules.promise, | |
156 | scripts/zpool-config/promise-raid0-1x16.sh, | |
157 | scripts/zpool-config/promise-raid10-8x2.sh, | |
158 | scripts/zpool-config/promise-raidz-2x8.sh, | |
159 | scripts/zpool-config/promise-raidz2-2x8.sh: | |
160 | Additional test configurations for a small 16 drive JBOD. | |
161 | ||
162 | * module/zfs/arc.c: Linux 2.6.31 compat, mutexes can now exceed 64 | |
163 | bytes depending on the the kernel build options. To account for | |
164 | this increase the pad size to 256 bytes. | |
165 | ||
166 | * module/zfs/vdev_disk.c: Linux 2.6.31 compat, to get the hard | |
167 | sector size use bdev_logical_block_size() this function replaces | |
168 | bdev_hardsect_size(). | |
169 | ||
170 | * module/zfs/zfs_rlock.c: Prevent gcc uninit compiler warning in | |
171 | zfs_range_unlock_reader(). | |
172 | ||
173 | * Makefile.am: Ensure *.order and *.markers build products are | |
174 | removed by distclean rule. | |
175 | ||
176 | 2009-11-02 Brian Behlendorf <behlendorf1@llnl.gov> | |
177 | ||
178 | * : Tag zfs-0.4.6 - Use 'git log --no-merges' for full change log. | |
179 | ||
180 | * Rebased to ZFS b121 from OpenSolaris. | |
181 | ||
182 | * module/zfs/vdev_disk.c: Finally a feature complete implementation: | |
183 | - Handle dynamic bio merge_bdev limitations when constructing the | |
184 | bio set associated with a dio. This previously prevented us from | |
185 | layering cleanly on the md and dm virtual devices. | |
186 | - Removed hard coded 512 byte sector size. | |
187 | - Correctly determine the device size when using a partition. | |
188 | - Hold and extra dio reference when submitting bio's using | |
189 | bio_submit() to prevent a completion race. | |
190 | ||
191 | * lib/libefi/*: Added fully function libefi library from Solaris. | |
192 | This allows us to properly create and access GPT style partition | |
193 | tables which are used when a whole device is added to a zpool. | |
194 | ||
195 | * cmd/zpool/zpool_vdev.c: Fully integrated zpool with Linux package | |
196 | libblkid. This allows zpool to identify existing devices of | |
197 | various types to prevent devices from accidentally being used. When | |
198 | given a whole device with a GPT partition table all partitions will | |
199 | be checked for existing filesystems. At the moment MBR style | |
200 | partition tables cannot be check and the force option must be used. | |
201 | ||
202 | * cmd/zpool/zpool_vdev.c: Solaris devid support has been removed in | |
203 | favor of Linux's udev. This means that a zpool device will always be | |
204 | opened using the path provided at configuration time. This may | |
205 | initially seem limiting but it has certain advantages: | |
206 | - When creating a zpool where the physical location of the device | |
207 | is NOT import simply create the pool using the /dev/disk/by-id paths. | |
208 | This will ensure that regardless of physical location the device | |
209 | will be properly located. | |
210 | - When creating a zpool where the physical location of the device | |
211 | is important use the /dev/disk/by-path paths. This will ensure that | |
212 | devices are never accidentally detected and used in an incorrect | |
213 | location which would compromise the redundancy of the system. | |
214 | - Ever better you can create use your own udev rules file to setup | |
215 | any mapping and naming convention you desire. One example of a | |
216 | custom rule is to map physical device locations using grid with | |
217 | numbers are letter for coordinates. Each letter might represent | |
218 | a specific bus/channel and each number a specific device. For large | |
219 | configurations this provides an easy way to identify devices. | |
220 | ||
221 | * module/zpios/zpios.c: Update to use kobject_set_name() for | |
222 | increased portability. | |
223 | ||
224 | * modules/*/*: Update module init/exit access points to use | |
225 | spl_module_{init,exit}() macro API. This ensures the cwd is | |
226 | immediately set to '/' and may be leveraged latter for any | |
227 | additional module setup/cleanup which is required. | |
228 | ||
229 | * cmd/ztest/ztest.c: Check ftrucate() return code to prevent | |
230 | warnings when --fortify-source options is used in rpm builds. | |
231 | ||
232 | * config/Rules.am: Set DEBUG/NDEBUG globally when building user | |
233 | space components. | |
234 | ||
235 | * scripts/zconfig.sh: Initial hook for running additional sanity | |
236 | tests are part of 'make check'. Currently, there are only two | |
237 | tests which do some basic configuration checking but they should | |
238 | be extended as much as possible to prevent regressions. Tests | |
239 | should also all be written so they run entirely in-tree. | |
240 | ||
241 | * scripts/zpios-sanity.sh: Initial hook for validating real IO | |
242 | using all block devices and all raid configurations. Supported | |
243 | device types include scsi, ide, md, dm, ram, loop, and file. | |
244 | Supported raid types include raid0, raid10, raidz, and raidz2. | |
245 | ||
246 | * scripts/zpool-config/*: Update dragon and x4550 configs to use | |
247 | custom udev rules file with <A-Z><1-N> naming convention. Add | |
248 | configs for md, dm, and ram block devices to verify functionality. | |
249 | ||
250 | * zfs-test.spec.in: Added zfs-test package which extends the existing | |
251 | in-tree test infrastructure such that it can be run as part of an | |
252 | installed package. This simplifies the testing of tagged releases. | |
253 | ||
254 | * zfs-modules.spec.in: Various spec file tweaks for the supported | |
255 | distros: RHEL5, RHEL6, SLES10, SLES11, Chaos4, Fedora 11. | |
256 | ||
257 | 2009-08-04 Brian Behlendorf <behlendorf1@llnl.gov> | |
258 | ||
259 | * : Tag zfs-0.4.5 - Use 'git log --no-merges' for full change log. | |
260 | ||
261 | * FC11 and SLES11 support: This includes all compatibility changes | |
262 | to support 2.6.29 based kernels and the required build system | |
263 | improvements. | |
264 | * lib/libspl/asm-generic/atomic.c: Generic user space atomic support. | |
265 | * module/zpios/zpios.c: Register a basic compat ioctl handler for | |
266 | 32-bit user vs 64-bit kernel compatibility. This is the default | |
267 | build environment for all 64-bit SLES systems. Additionally | |
268 | replace the use of 'struct timespec' which uses longs internally | |
269 | and is therefore different sizes on 32-bit vs 64-bit objects with | |
270 | 'struct zpios_timespec_t'.a | |
271 | * config/kernel.m4: Check arch/default path when detecting kernel | |
272 | objects under SLES. We still preferentially use arch/arch if | |
273 | available but if that fails it is acceptable to use default. | |
274 | * config/kernel.m4: Remove LINUXINCLUDE from autoconf wrapper. | |
275 | This breaks the 2.6.28+ kernels build system, all kernel build systems | |
276 | at least post 2.6.16 will set this properly so we should not. | |
277 | * lib/libspl/include/assert.h: Add ASSERTV macro to simplify removing | |
278 | variables (the V in ASSERTV) which are only used in ASSERT(). | |
279 | Also revert all previously modified ASSERT()s to their original | |
280 | definitions and use the ASSERTV macro to handle unused variables. | |
281 | * module/zpios/zpios.c: Use spl device interfaces for portability. | |
282 | * scripts/common.sh: The losetup -f option is unavailable for | |
283 | SLES10 use the unused_loop_device() common function. Additionally | |
284 | LOSETUP is now used to portably reference the losetup binary. | |
285 | * module/zfs/vdev_disk.c: Unused destroy_dirty_buffers arg removed. | |
286 | * module/zfs/vdev_disk.c: BIO_RW_SYNC renamed to BIO_RW_SYNCIO. | |
287 | * module/zfs/vdev_disk.c: open/close_bdev_excl() renamed to | |
288 | open/close_bdev_exclusive(). | |
289 | * module/zfs/vdev_disk.c: Empty write barriers are supported as of | |
290 | linux 2.6.24 and are now used to implement DKIOCFLUSHWRITECACHE. | |
291 | * module/zfs/vdev_disk.c: The bi_end_io API changes make partial | |
292 | IO's impossible handle this case cleanly. | |
293 | * module/zfs/vdev_disk.c: BIO_RW_FAILFAST replaced with | |
294 | BIO_RW_FAILFAST_{DEV|_TRANSPORT|_DRIVER}, use the legacy | |
295 | BIO_RW_FAILFAST flag if it exists for now. | |
296 | * module/zfs/dmu_objset.c, module/zfs/spa_history.c: Excessively | |
297 | large stack frames (>2048) were detected in dmu_objset_snapshot() | |
298 | and spa_history_log() and were reduced by allocating from the heap. | |
299 | ||
300 | * Rebased to ZFS b117 from OpenSolaris: | |
301 | * module/zfs/dmu.c: Update zerocopy patch to be consistent with | |
302 | new flags arg passed to dmu_read(). | |
303 | * module/zpios/zpios.c: Update zpios to be aware of the new flags | |
304 | argument available in dmu_read(). Additionally add a zpios command | |
305 | line flag to set the DMU_READ_NO_PREFETCH flag for a test. | |
306 | * module/zfs/include/sys/zfs_context.h: Wrap new sysevent includes | |
307 | until sysevent or something like it is implemented. | |
308 | * module/zfs/zfs_ioctl.c: Wrap all the ACL interfaces with HAVE_ZPL. | |
309 | They are integrated with the vfs layer which is not yet supported. | |
310 | * module/zcommon/zfs_prop.c: Export new quota related symbols. | |
311 | * lib/libzfs/libzfs_util.c: Increase buffer size for nvlist which | |
312 | is needed for large configurations. | |
313 | ||
314 | * Bug fixes: | |
315 | * lib/libspl/include/sys/zfs_debug.h: Removed duplicate file. | |
316 | * lib/libspl/include/sys/isa_defs.h: Fixed missing macro definitions | |
317 | for little endian and big endian. | |
318 | * cmd/zpios/zpios_main.c: Pretty-up the zpios 'make check' output. | |
319 | * module/zfs/vdev_disk.c: Honor spa_mode() when opening block devs. | |
320 | * module/zfs/vdev_disk.c: Initial error handling added to | |
321 | vdev_disk_io_done() to revalidate the media on EIO. | |
322 | * lib/libzfs/libzfs_util.c: Fix an accidentally introduced formatting | |
323 | issue in zfs_nicenum() output. | |
324 | ||
325 | 2009-07-02 Brian Behlendorf <behlendorf1@llnl.gov> | |
326 | ||
327 | * : Tag zfs-0.4.4 - Use 'git log --no-merges' for full change log. | |
328 | ||
329 | * : Generic distro friendly build system / packaging improvements | |
330 | for RPM based distros including CHAOS, RHEL, Fedora, and SLES. | |
331 | ||
332 | These changes bring the zfs-0.4.4 tree in to compliance with | |
333 | the spl-0.4.4 packaging changes. The bottom line is 2 source | |
334 | rpms and 4 binary rpms will now be generated when creating | |
335 | packages there will be: | |
336 | ||
337 | zfs-<version>.src.rpm | |
338 | - Fully rebuildable source rpm for libzfs and utils. | |
339 | zfs-modules-<version>.src.rpm | |
340 | - Fully rebuildable source rpm for kernel modules. | |
341 | ||
342 | zfs-<version>.<arch>.rpm | |
343 | - Binary rpm for libzfs and utils. The utils in this package are | |
344 | compatible with all zfs-module rpms of the same version. | |
345 | zfs-devel-<version>.<arch>.rpm | |
346 | - Binary rpm containing headers for building against libzfs libraries. | |
347 | ||
348 | zfs-modules-<verion>-<kernel>.arch.rpm | |
349 | - Binary rpm containing the kernel modules for a specific kernel build. | |
350 | The package name contains the kernel version and you should have one | |
351 | of these packages installed to match every kernel on your system. | |
352 | zfs-modules-devel-<verion>-<kernel>.arch.rpm | |
353 | - Binary rpm containing development header and module symbols needed | |
354 | for building additional kernel modules which are dependent on the | |
355 | zfs module stack. | |
356 | ||
357 | * : SLES9/10 distro support added: Several significant updates to | |
358 | the build system were required to support this including: | |
359 | ||
360 | - Autoconf macros updated to be aware of the standard install | |
361 | locations for SLES kernel sources and build objects. Additionally | |
362 | changes were made to support multiple names for Module{s}.symvers. | |
363 | - By default on SLES all user space builds are 32-bit even on | |
364 | 64-bit arches. This means we need to be careful to pass -m64 in | |
365 | the autoconf checks which probe the kernel. Additionally, | |
366 | ioctl_compat handles still need to be added so 32-bit user | |
367 | binarys can perform ioctls with the 64-bit kernel. | |
368 | ||
369 | * : Powerpc64 support added: | |
370 | ||
371 | - 64-bit user space atomic support for power64 was obtained from | |
372 | an old version of OpenSolaris which offered minimal powerpc support. | |
373 | The atomic support is not 100% fully implemented but it's a good | |
374 | first step towards cleanly supporting the architecture. | |
375 | - Added powerpc ISA type. | |
376 | - Explicitly use signed char for portability. On x86/x86_64 | |
377 | systems the default char type is signed, on ppc/ppc64 systems | |
378 | the default char type is unsigned. | |
379 | - Core target arch support for conditional compilation of SUBDIRs. | |
380 | Required by libspl for its arch specific atomic implementations. | |
381 | ||
382 | * COPYRIGHT: Readded accidentally dropped COPYRIGHT, it just | |
383 | references the OPENSOLARIS.LICENSE which was still in the project. | |
384 | ||
385 | * module/zfs/dmu_tx.c: Add EXPORT_SYMBOL(dmu_tx_callback_register). | |
386 | ||
387 | * config/user-zlib.m4: Add basic zlib autoconf check for user space. | |
388 | ||

391 | * : Tag zfs-0.4.3 - Use 'git log --no-merges' for full change log. | |
392 | ||
393 | * : Rebased to ZFS b108 from OpenSolaris | |
394 | ||
395 | * configure.ac, *Makefile.am: Build system update. This includes | |
396 | resolving various build issues and adding support for the remaining | |
397 | common build targets. Available targets now include: | |
398 | ||
399 | - make all # Build everything | |
400 | - make install # Install everything | |
401 | - make clean # Clean up build products | |
402 | - make distclean # Clean up everything | |
403 | - make dist # Create package tarball | |
404 | - make srpm # Create package source RPM | |
405 | - make rpm # Create package binary RPMs | |
406 | - make tags # Create ctags and etags for everything | |
407 | ||
408 | Extra care was taken to ensure that the source RPMs are fully | |
409 | rebuildable against Fedora/RHEL/Chaos kernels. To build binary | |
410 | RPMs from the source RPM for your system simply run: | |
411 | ||
412 | rpmbuild --rebuild zfs-x.y.z-1.src.rpm | |
413 | ||
414 | This will produce two binary RPMs with correct 'requires' | |
415 | dependencies for your kernel. One will contain all zfs modules | |
416 | and support utilities, the other is a devel package for compiling | |
417 | additional kernel modules which are dependent on the zfs. | |
418 | ||
419 | zfs-x.y.z-1_<kernel version>.x86_64.rpm | |
420 | zfs-devel-x.y.2-1_<kernel version>.x86_64.rpm | |
421 | ||
422 | * config/kernel.m4, config/Rules.am: Removed the build options | |
423 | -Wno-unused -Wno-missing -Wno-unused -Wno-parentheses and | |
424 | -Wno-unknown-pragmas. All upstream warnings which were being | |
425 | suppressed by these options are now handled in the matching | |
426 | gcc-* topic branch. | |
427 | ||
428 | * zpios: Various zpios and test infrastructure improvements. | |
429 | ||
430 | * feature-commit-cb: New feature commit callbacks. | |
431 | ||
432 | * : Various bug fixes which are more clearly detailed in the | |
433 | git commit logs. For a detailed summary of changes post version | |
434 | 0.4.2, check out the 'top' topic branch and view the commit logs. | |
435 | ||
436 | git checkout top | |
437 | git log --no-merges -53 | |

439 | 2009-02-05 Brian Behlendorf <behlendorf1@llnl.gov> | |
440 | ||
441 | * : Tag zfs-0.4.2 | |
442 | ||
443 | * lib/libzfs/libzfs_util.c: Remove mknod() this is now handled by | |
444 | by the SPL with an upcall even without GPL-only symbols. | |
445 | ||
446 | * module/zfs/vdev_diskc: Updated linux vdev_disk interfaces to issue | |
447 | multiple bios if needed due to the maximum request size being smaller | |
448 | than the request size passed down from the spa. | |
449 | ||
450 | * scripts/zpool-config/lo-*: Add loopback based test configs. | |
451 | ||
452 | 2009-01-21 Brian Behlendorf <behlendorf1@llnl.gov> | |
453 | ||
454 | * : Tag zfs-0.4.1 | |
455 | ||
456 | * : Rebased to ZFS b105 from OpenSolaris | |
457 | ||
458 | * : Restructured project and build system to more closely | |
459 | mirror the code organization used in OpenSolaris. This | |
460 | allows us minimize the changes to upstream source needed, | |
461 | and allows concurrent user+kernel space builds of all components. | |
462 | ||
463 | 2008-11-19 Brian Behlendorf <behlendorf1@llnl.gov> | |
464 | ||
465 | * : Tag zfs-0.4.0 | |
466 | ||
467 | * : ZFS project migrated from Subversion which leveraged a | |
468 | quilt based patch stack to Git and a TopGit managed patch | |
469 | stack. The new method treats all patches as Git branches | |
470 | which can be more easily shared for distributed development. | |
471 | Consult the top level GIT file for detailed information on | |
472 | how to properly develop for this package using Git+TopGit. | |
473 | ||
474 | 2008-11-12 Brian Behlendorf <behlendorf1@llnl.gov> | |
475 | ||
476 | * : Tag zfs-0.3.4 | |
477 | ||
478 | * zfs-07-create-dev-zfs.patch: | |
479 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
480 | - Make libzfs create /dev/zfs if it doesn't exist. | |
481 | ||
482 | * zfs-05-check-zvol-size.patch: | |
483 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
484 | - Properly check zvol size under Linux. | |
485 | ||
486 | * zfs-04-no-openat-fdopendir.patch: | |
487 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
488 | - Do not use openat() and fdopendir() since they are not available | |
489 | on older systems. | |
490 | ||
491 | * zfs-03-fix-bio-sync.patch: | |
492 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
493 | - Fix memory corruption in RHEL4 due to synchronous IO becoming | |
494 | asynchronous. | |
495 | ||
496 | 2008-11-06 Brian Behlendorf <behlendorf1@llnl.gov> | |
497 | ||
498 | * zfs-02-zpios-fix-stuck-thread-memleak.patch: | |
499 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
500 | - Fix stuck threads and memory leaks when errors occur while writing. | |
501 | ||
502 | * zfs-01-zpios-arg-corruption.patch: | |
503 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
504 | - Fix zpios cmd line argument corruption problem. | |
505 | ||
506 | * zfs-00-minor-fixes.patch: | |
507 | Ricardo M. Correia <Ricardo.M.Correia@sun.com> | |
508 | - Minor build system improvements | |
509 | - Minor script improvements | |
510 | - Create a full copy and not a link tree with quilt | |
511 | - ZPIOS_MAJOR changed from 231 to 232 | |
512 | - BIO_RW_BARRIER flag removed from IO request | |
513 | ||
514 | 2008-06-30 Brian Behlendorf <behlendorf1@llnl.gov> | |
515 | ||
516 | * : Tag zfs-0.3.3 | |
517 | ||
518 | * : Minor script updates and tweaks to be compatible with | |
519 | the latest version of the SPL. | |
520 | ||
521 | 2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov> | |
522 | ||
523 | * vdev_disk.diff: Replace vdev_disk implementation which was | |
524 | based on the kmalloc'ed logical address space with a version | |
525 | which works with vmalloc'ed memory in the virtual address space. | |
526 | This was done to support the new SPL slab implementation which | |
527 | is based on virtual addresses to avoid the need for contigeously | |
528 | allocated memory. | |
529 | ||
530 | 2008-06-05 Brian Behlendorf <behlendorf1@llnl.gov> | |
531 | ||
532 | * arc-vm-integration.diff: Reduce maximum default arc memory | |
533 | usage to 1/4 of total system memory. Because all the bulk data | |
534 | is still allocated on the slab memory fragmentation is a serious | |
535 | concern. To address this in the short term we simply need to | |
536 | leave lots of free memory. | |
537 | ||
538 | * fix-stack.diff: First step towards reducing stack usage so | |
539 | we can run the full ZFS stack using a stock kernel. | |
540 | ||
541 | 2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov> | |
542 | ||
543 | * : Tag zfs-0.3.2 | |
544 | ||
545 | * : Extensive improvements to the build system to detect kernel | |
546 | API changes so we can flexibly build with a wider range of kernel | |
547 | versions. The code has now been testing with the 2.6.18-32chaos | |
548 | and 2.6.25.3-18.fc9 kernels, however we should also be compatible | |
549 | with other kernels in the range of 2.6.18-2.6.25. The only | |
550 | remaining issue preventing us from running with a stock | |
551 | kernel is ZFS stack usage. | |
552 | ||
553 | 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov> | |
554 | ||
555 | * : Tag zfs-0.3.1 | |
556 | ||
557 | * : License headers including URCL added for release. | |
558 | ||
559 | 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov> | |
560 | ||
561 | * : Tag zfs-0.3.0 | |
562 | ||
563 | * configure.ac: Improved autotools support and configurable debug. | |
564 | ||
565 | 2008-05-15 Brian Behlendorf <behlendorf1@llnl.gov> | |
566 | ||
567 | * : Updating original ZFS sources to build 89 which | |
568 | includes the new write throttling changes plus support | |
569 | for using ZFS as your root device. Neither of which | |
570 | will work exactly right without some more work but this | |
571 | gets us much closers to the latest source. | |
572 | ||
573 | ||
574 | 2008-02-28 Brian Behlendorf <behlendorf1@llnl.gov> | |
575 | ||
576 | * : First attempt based on SPL module and zfs-lustre sources |
