Please use the git commit - logs for a full records of changes: 'git log --no-merges' - -2010-05-21 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.9 - Use 'git log --no-merges' for full change log. - - * : Build system improvements: - - Added support for the 'make -s' silent build option. - - Allow zfs_config.h to be included by dependent packages. - - Minor spec file updates. - - Minor build system message updates. - - * : Topic branch cleanup. Several old branches were removed and - numerous hunks which were accidentaly commited to incorrect topic - branches in the past were relocated to the correct topic branch. - - * *.c, *.h, *.sh, AUTHORS, COPYING, COPYRIGHT, DISCLAIMER, README: - Added standard header to source files which includes the copyright, - license, and author information. Additionally, updated the listed - top level files to the latest versions. - - * cmd/zpool/zpool_vdev.c: Check all partitions with check_file() - even when no libblkid is found. This oversight would result in - ZFS not detecting existing filesystems on partitions. - - * module/zfs/fm.c, module/zfs/zfs_fm, libzfs/libzfs_pool.c: - Added zevents which are similar to Solaris FMA support. The - existing FMA and sysevent call points in ZFS were unified in - to a single event type and used to create a user space visible - event notification system under Linux. The new 'zpool events' - command can be used to show all recent ZFS events. - - * module/zfs/spa.c, module/zfs/zil.c: Suppress large memory - allocation warnings for two particular kmem_alloc()'s. For - now we can live with them as is but long term a way should be - found to perform small allocations or use the vmem based slab. - - * module/zfs/zvol.c: Recreate volume and snapshot /dev links during - module load. Links in /dev for volumes/snapshots were only being - created at volume/snapshot creation time. Those links are now also - created dynamically at module load time based on the spa config. - - * module/zfs/zvol.c, module/zfs/include/sys/blkdev.h: The handler - zvol_request() should use the unlocked version of blk_end_request() - to avoid a deadlock in the ZVOL. - -2010-03-11 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.8 - Use 'git log --no-merges' for full change log. - - * : Build system improvements: - - Remove Module.markers and Module.symver{s} in clean target. - - Improved kernel source detection when none specified. - - Fix RPM definitions for the unknown distro/installation. - - Check for spl in ../spl if not found in install path. - - Include all headers regardless of depth in packages. - - Allow recursive configure/make. - - * lib/libzpool/kernel.c: Fixed several zdb bugs when opening a pool - - zdb wasn't getting the correct device size when the vdev is a - block device. In Solaris, fstat64() returns the device size but - in Linux an ioctl() is needed. - - make sure that we don't try to open a block device in write mode - from userspace. This shouldn't happen, because zdb opens devices - in read-only mode, and ztest only uses files. - - * lib/libspl/include/umem.h: Add umem_alloc_aligned() and honor - cache_align field for umem cache. Under linux we open block devices - with O_DIRECT which means we must provide aligned memory buffers. - - * lib/libzpool/kernel.c: Fix some incorrect error handling. In - vn_open(), if fstat64() returned an error, the real errno was being - obscured by calling close(). - - * scripts/*: Fix scripts to work when invoked from other directories. - - * module/zfs/arc.c: Fix struct ht_lock padding in arc.c. - - * lib/libefi/include/sys/uuid.h: Fix duplicate uuid_t typedef. - - * module/zfs/txg.c: Use CPU percentages for number of commit cb - threads. This doesn't change number of threads in the kernel, but it - reduces number of threads in ztest (important due to 32-bit address - limitations). - - * cmd/ztest/ztest.c: Clean up emulation of kernel threads in - userspace. Updated to use pthread thread specific data rather than - keeping a global list. This also fixes at least one easily - reproducible crash in ztest - - * META, config/kernel.m4: Add configure check for kernel build - options which are incompatible with the license. If your building - against a kernel deemed incompatible configure will fail and - suggest how you should rebuild your kernel. - - * config/kernel-fmode-t.m4: Linux 2.6.28 compat, add a check for the - fmode_t type. This typedef first appears in 2.6.28 kernels as part - of some block device operation reworking. - - * module/zfs/dmu_send.c: No inline to keep dmu_recv_stream() stack - frame less than 1024 bytes. Recent builds against 2.6.31 flagged - dmu_recv_stream() as stack heavy. Further analysis of this function - should be performed to further reduce its stack usage. - - * scripts/common.sh: Split the udev rule from a specific configuration - by providing a generic 60-zpool.rules file which uses a small helper - util 'zpool_id' to parse a configuration file by default located in - /etc/zfs/zdev.conf. The helper script maps a by-path udev name to a - more friendly name of <channel><rank> for large configurations. - - Additionally, when running zpool-create.sh in-tree it will no longer - use udev because we would have to copy certain helper scripts in to - the installed system. To avoid this the config file in simply - parsed and symlinks are created in your working tree. The script - will use udev if it as run as part of an installed zfs-test package. - - * module/zfs/zvol.c: Use check_disk_change() instead of - revalidate_disk(). For 2.6.27 kernels are earlier revalidate_disk() - was not available. However, check_disk_change() has been available - for far longer and will properly inform the kernel of the volume - change for both older and newer kernels. - - * module/zfs/dmu.c: Fixed incorrect ASSERT3S() added by ZVOL. - - * module/zfs/vdev_raidz.c, module/zfs/zvol.c: Minor fixes for 32-bit. - - * scripts/zfs-update.sh, man/man8/*: Added man pages based on the - latest documentation and modified zfs-update.sh script to update them. - - * .gitignore: Updated .gitignore rules to exclude build products. - -2009-11-24 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.7 - Use 'git log --no-merges' for full change log. - - * module/zcommon/include/sys/fs/zfs.h, module/zfs/include/sys/blkdev.h, - module/zfs/include/sys/dmu.h, module/zfs/dmu.c, - module/zfs/include/sys/zvol.h, module/zfs/zvol.c, - module/zfs/zfs_ioctl.c: - Added the ZVOL block device, with the addition of the ZVOL real ZFS - based block devices are available and can be compared head to head - with Linux's MD and LVM block drivers. The Linux ZVOL has not yet - had any performance work done but from a user perspective it should - be functionally complete and behave like any other Linux block device. - The ZVOL has so far been tested using zconfig.sh on the following - x86_64 based platforms: FC11, CHAOS4, RHEL5, RHEL6, and SLES11. - However, more testing is required to ensure everything is working - as designed. - - * scripts/udev-rules/99-zpool.rules.promise, - scripts/zpool-config/promise-raid0-1x16.sh, - scripts/zpool-config/promise-raid10-8x2.sh, - scripts/zpool-config/promise-raidz-2x8.sh, - scripts/zpool-config/promise-raidz2-2x8.sh: - Additional test configurations for a small 16 drive JBOD. - - * module/zfs/arc.c: Linux 2.6.31 compat, mutexes can now exceed 64 - bytes depending on the the kernel build options. To account for - this increase the pad size to 256 bytes. - - * module/zfs/vdev_disk.c: Linux 2.6.31 compat, to get the hard - sector size use bdev_logical_block_size() this function replaces - bdev_hardsect_size(). - - * module/zfs/zfs_rlock.c: Prevent gcc uninit compiler warning in - zfs_range_unlock_reader(). - - * Makefile.am: Ensure *.order and *.markers build products are - removed by distclean rule. - -2009-11-02 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.6 - Use 'git log --no-merges' for full change log. - - * Rebased to ZFS b121 from OpenSolaris. - - * module/zfs/vdev_disk.c: Finally a feature complete implementation: - - Handle dynamic bio merge_bdev limitations when constructing the - bio set associated with a dio. This previously prevented us from - layering cleanly on the md and dm virtual devices. - - Removed hard coded 512 byte sector size. - - Correctly determine the device size when using a partition. - - Hold and extra dio reference when submitting bio's using - bio_submit() to prevent a completion race. - - * lib/libefi/*: Added fully function libefi library from Solaris. - This allows us to properly create and access GPT style partition - tables which are used when a whole device is added to a zpool. - - * cmd/zpool/zpool_vdev.c: Fully integrated zpool with Linux package - libblkid. This allows zpool to identify existing devices of - various types to prevent devices from accidentally being used. When - given a whole device with a GPT partition table all partitions will - be checked for existing filesystems. At the moment MBR style - partition tables cannot be check and the force option must be used. - - * cmd/zpool/zpool_vdev.c: Solaris devid support has been removed in - favor of Linux's udev. This means that a zpool device will always be - opened using the path provided at configuration time. This may - initially seem limiting but it has certain advantages: - - When creating a zpool where the physical location of the device - is NOT import simply create the pool using the /dev/disk/by-id paths. - This will ensure that regardless of physical location the device - will be properly located. - - When creating a zpool where the physical location of the device - is important use the /dev/disk/by-path paths. This will ensure that - devices are never accidentally detected and used in an incorrect - location which would compromise the redundancy of the system. - - Ever better you can create use your own udev rules file to setup - any mapping and naming convention you desire. One example of a - custom rule is to map physical device locations using grid with - numbers are letter for coordinates. Each letter might represent - a specific bus/channel and each number a specific device. For large - configurations this provides an easy way to identify devices. - - * module/zpios/zpios.c: Update to use kobject_set_name() for - increased portability. - - * modules/*/*: Update module init/exit access points to use - spl_module_{init,exit}() macro API. This ensures the cwd is - immediately set to '/' and may be leveraged latter for any - additional module setup/cleanup which is required. - - * cmd/ztest/ztest.c: Check ftrucate() return code to prevent - warnings when --fortify-source options is used in rpm builds. - - * config/Rules.am: Set DEBUG/NDEBUG globally when building user - space components. - - * scripts/zconfig.sh: Initial hook for running additional sanity - tests are part of 'make check'. Currently, there are only two - tests which do some basic configuration checking but they should - be extended as much as possible to prevent regressions. Tests - should also all be written so they run entirely in-tree. - - * scripts/zpios-sanity.sh: Initial hook for validating real IO - using all block devices and all raid configurations. Supported - device types include scsi, ide, md, dm, ram, loop, and file. - Supported raid types include raid0, raid10, raidz, and raidz2. - - * scripts/zpool-config/*: Update dragon and x4550 configs to use - custom udev rules file with <A-Z><1-N> naming convention. Add - configs for md, dm, and ram block devices to verify functionality. - - * zfs-test.spec.in: Added zfs-test package which extends the existing - in-tree test infrastructure such that it can be run as part of an - installed package. This simplifies the testing of tagged releases. - - * zfs-modules.spec.in: Various spec file tweaks for the supported - distros: RHEL5, RHEL6, SLES10, SLES11, Chaos4, Fedora 11. - -2009-08-04 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.5 - Use 'git log --no-merges' for full change log. - - * FC11 and SLES11 support: This includes all compatibility changes - to support 2.6.29 based kernels and the required build system - improvements. - * lib/libspl/asm-generic/atomic.c: Generic user space atomic support. - * module/zpios/zpios.c: Register a basic compat ioctl handler for - 32-bit user vs 64-bit kernel compatibility. This is the default - build environment for all 64-bit SLES systems. Additionally - replace the use of 'struct timespec' which uses longs internally - and is therefore different sizes on 32-bit vs 64-bit objects with - 'struct zpios_timespec_t'.a - * config/kernel.m4: Check arch/default path when detecting kernel - objects under SLES. We still preferentially use arch/arch if - available but if that fails it is acceptable to use default. - * config/kernel.m4: Remove LINUXINCLUDE from autoconf wrapper. - This breaks the 2.6.28+ kernels build system, all kernel build systems - at least post 2.6.16 will set this properly so we should not. - * lib/libspl/include/assert.h: Add ASSERTV macro to simplify removing - variables (the V in ASSERTV) which are only used in ASSERT(). - Also revert all previously modified ASSERT()s to their original - definitions and use the ASSERTV macro to handle unused variables. - * module/zpios/zpios.c: Use spl device interfaces for portability. - * scripts/common.sh: The losetup -f option is unavailable for - SLES10 use the unused_loop_device() common function. Additionally - LOSETUP is now used to portably reference the losetup binary. - * module/zfs/vdev_disk.c: Unused destroy_dirty_buffers arg removed. - * module/zfs/vdev_disk.c: BIO_RW_SYNC renamed to BIO_RW_SYNCIO. - * module/zfs/vdev_disk.c: open/close_bdev_excl() renamed to - open/close_bdev_exclusive(). - * module/zfs/vdev_disk.c: Empty write barriers are supported as of - linux 2.6.24 and are now used to implement DKIOCFLUSHWRITECACHE. - * module/zfs/vdev_disk.c: The bi_end_io API changes make partial - IO's impossible handle this case cleanly. - * module/zfs/vdev_disk.c: BIO_RW_FAILFAST replaced with - BIO_RW_FAILFAST_{DEV|_TRANSPORT|_DRIVER}, use the legacy - BIO_RW_FAILFAST flag if it exists for now. - * module/zfs/dmu_objset.c, module/zfs/spa_history.c: Excessively - large stack frames (>2048) were detected in dmu_objset_snapshot() - and spa_history_log() and were reduced by allocating from the heap. - - * Rebased to ZFS b117 from OpenSolaris: - * module/zfs/dmu.c: Update zerocopy patch to be consistent with - new flags arg passed to dmu_read(). - * module/zpios/zpios.c: Update zpios to be aware of the new flags - argument available in dmu_read(). Additionally add a zpios command - line flag to set the DMU_READ_NO_PREFETCH flag for a test. - * module/zfs/include/sys/zfs_context.h: Wrap new sysevent includes - until sysevent or something like it is implemented. - * module/zfs/zfs_ioctl.c: Wrap all the ACL interfaces with HAVE_ZPL. - They are integrated with the vfs layer which is not yet supported. - * module/zcommon/zfs_prop.c: Export new quota related symbols. - * lib/libzfs/libzfs_util.c: Increase buffer size for nvlist which - is needed for large configurations. - - * Bug fixes: - * lib/libspl/include/sys/zfs_debug.h: Removed duplicate file. - * lib/libspl/include/sys/isa_defs.h: Fixed missing macro definitions - for little endian and big endian. - * cmd/zpios/zpios_main.c: Pretty-up the zpios 'make check' output. - * module/zfs/vdev_disk.c: Honor spa_mode() when opening block devs. - * module/zfs/vdev_disk.c: Initial error handling added to - vdev_disk_io_done() to revalidate the media on EIO. - * lib/libzfs/libzfs_util.c: Fix an accidentally introduced formatting - issue in zfs_nicenum() output. - -2009-07-02 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.4 - Use 'git log --no-merges' for full change log. - - * : Generic distro friendly build system / packaging improvements - for RPM based distros including CHAOS, RHEL, Fedora, and SLES. - - These changes bring the zfs-0.4.4 tree in to compliance with - the spl-0.4.4 packaging changes. The bottom line is 2 source - rpms and 4 binary rpms will now be generated when creating - packages there will be: - - zfs-<version>.src.rpm - - Fully rebuildable source rpm for libzfs and utils. - zfs-modules-<version>.src.rpm - - Fully rebuildable source rpm for kernel modules. - - zfs-<version>.<arch>.rpm - - Binary rpm for libzfs and utils. The utils in this package are - compatible with all zfs-module rpms of the same version. - zfs-devel-<version>.<arch>.rpm - - Binary rpm containing headers for building against libzfs libraries. - - zfs-modules-<verion>-<kernel>.arch.rpm - - Binary rpm containing the kernel modules for a specific kernel build. - The package name contains the kernel version and you should have one - of these packages installed to match every kernel on your system. - zfs-modules-devel-<verion>-<kernel>.arch.rpm - - Binary rpm containing development header and module symbols needed - for building additional kernel modules which are dependent on the - zfs module stack. - - * : SLES9/10 distro support added: Several significant updates to - the build system were required to support this including: - - - Autoconf macros updated to be aware of the standard install - locations for SLES kernel sources and build objects. Additionally - changes were made to support multiple names for Module{s}.symvers. - - By default on SLES all user space builds are 32-bit even on - 64-bit arches. This means we need to be careful to pass -m64 in - the autoconf checks which probe the kernel. Additionally, - ioctl_compat handles still need to be added so 32-bit user - binarys can perform ioctls with the 64-bit kernel. - - * : Powerpc64 support added: - - - 64-bit user space atomic support for power64 was obtained from - an old version of OpenSolaris which offered minimal powerpc support. - The atomic support is not 100% fully implemented but it's a good - first step towards cleanly supporting the architecture. - - Added powerpc ISA type. - - Explicitly use signed char for portability. On x86/x86_64 - systems the default char type is signed, on ppc/ppc64 systems - the default char type is unsigned. - - Core target arch support for conditional compilation of SUBDIRs. - Required by libspl for its arch specific atomic implementations. - - * COPYRIGHT: Readded accidentally dropped COPYRIGHT, it just - references the OPENSOLARIS.LICENSE which was still in the project. - - * module/zfs/dmu_tx.c: Add EXPORT_SYMBOL(dmu_tx_callback_register). - - * config/user-zlib.m4: Add basic zlib autoconf check for user space. - -2009-03-20 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.3 - Use 'git log --no-merges' for full change log. - - * : Rebased to ZFS b108 from OpenSolaris - - * configure.ac, *Makefile.am: Build system update. This includes - resolving various build issues and adding support for the remaining - common build targets. Available targets now include: - - - make all # Build everything - - make install # Install everything - - make clean # Clean up build products - - make distclean # Clean up everything - - make dist # Create package tarball - - make srpm # Create package source RPM - - make rpm # Create package binary RPMs - - make tags # Create ctags and etags for everything - - Extra care was taken to ensure that the source RPMs are fully - rebuildable against Fedora/RHEL/Chaos kernels. To build binary - RPMs from the source RPM for your system simply run: - - rpmbuild --rebuild zfs-x.y.z-1.src.rpm - - This will produce two binary RPMs with correct 'requires' - dependencies for your kernel. One will contain all zfs modules - and support utilities, the other is a devel package for compiling - additional kernel modules which are dependent on the zfs. - - zfs-x.y.z-1_<kernel version>.x86_64.rpm - zfs-devel-x.y.2-1_<kernel version>.x86_64.rpm - - * config/kernel.m4, config/Rules.am: Removed the build options - -Wno-unused -Wno-missing -Wno-unused -Wno-parentheses and - -Wno-unknown-pragmas. All upstream warnings which were being - suppressed by these options are now handled in the matching - gcc-* topic branch. - - * zpios: Various zpios and test infrastructure improvements. - - * feature-commit-cb: New feature commit callbacks. - - * : Various bug fixes which are more clearly detailed in the - git commit logs. For a detailed summary of changes post version - 0.4.2, check out the 'top' topic branch and view the commit logs. - - git checkout top - git log --no-merges -53 - -2009-02-05 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.2 - - * lib/libzfs/libzfs_util.c: Remove mknod() this is now handled by - by the SPL with an upcall even without GPL-only symbols. - - * module/zfs/vdev_diskc: Updated linux vdev_disk interfaces to issue - multiple bios if needed due to the maximum request size being smaller - than the request size passed down from the spa. - - * scripts/zpool-config/lo-*: Add loopback based test configs. - -2009-01-21 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.1 - - * : Rebased to ZFS b105 from OpenSolaris - - * : Restructured project and build system to more closely - mirror the code organization used in OpenSolaris. This - allows us minimize the changes to upstream source needed, - and allows concurrent user+kernel space builds of all components. - -2008-11-19 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.4.0 - - * : ZFS project migrated from Subversion which leveraged a - quilt based patch stack to Git and a TopGit managed patch - stack. The new method treats all patches as Git branches - which can be more easily shared for distributed development. - Consult the top level GIT file for detailed information on - how to properly develop for this package using Git+TopGit. - -2008-11-12 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.3.4 - - * zfs-07-create-dev-zfs.patch: - Ricardo M. Correia <[email protected]> - - Make libzfs create /dev/zfs if it doesn't exist. - - * zfs-05-check-zvol-size.patch: - Ricardo M. Correia <[email protected]> - - Properly check zvol size under Linux. - - * zfs-04-no-openat-fdopendir.patch: - Ricardo M. Correia <[email protected]> - - Do not use openat() and fdopendir() since they are not available - on older systems. - - * zfs-03-fix-bio-sync.patch: - Ricardo M. Correia <[email protected]> - - Fix memory corruption in RHEL4 due to synchronous IO becoming - asynchronous. - -2008-11-06 Brian Behlendorf <[email protected]> - - * zfs-02-zpios-fix-stuck-thread-memleak.patch: - Ricardo M. Correia <[email protected]> - - Fix stuck threads and memory leaks when errors occur while writing. - - * zfs-01-zpios-arg-corruption.patch: - Ricardo M. Correia <[email protected]> - - Fix zpios cmd line argument corruption problem. - - * zfs-00-minor-fixes.patch: - Ricardo M. Correia <[email protected]> - - Minor build system improvements - - Minor script improvements - - Create a full copy and not a link tree with quilt - - ZPIOS_MAJOR changed from 231 to 232 - - BIO_RW_BARRIER flag removed from IO request - -2008-06-30 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.3.3 - - * : Minor script updates and tweaks to be compatible with - the latest version of the SPL. - -2008-06-13 Brian Behlendorf <[email protected]> - - * vdev_disk.diff: Replace vdev_disk implementation which was - based on the kmalloc'ed logical address space with a version - which works with vmalloc'ed memory in the virtual address space. - This was done to support the new SPL slab implementation which - is based on virtual addresses to avoid the need for contigeously - allocated memory. - -2008-06-05 Brian Behlendorf <[email protected]> - - * arc-vm-integration.diff: Reduce maximum default arc memory - usage to 1/4 of total system memory. Because all the bulk data - is still allocated on the slab memory fragmentation is a serious - concern. To address this in the short term we simply need to - leave lots of free memory. - - * fix-stack.diff: First step towards reducing stack usage so - we can run the full ZFS stack using a stock kernel. - -2008-06-04 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.3.2 - - * : Extensive improvements to the build system to detect kernel - API changes so we can flexibly build with a wider range of kernel - versions. The code has now been testing with the 2.6.18-32chaos - and 2.6.25.3-18.fc9 kernels, however we should also be compatible - with other kernels in the range of 2.6.18-2.6.25. The only - remaining issue preventing us from running with a stock - kernel is ZFS stack usage. - -2008-05-21 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.3.1 - - * : License headers including URCL added for release. - -2008-05-21 Brian Behlendorf <[email protected]> - - * : Tag zfs-0.3.0 - - * configure.ac: Improved autotools support and configurable debug. - -2008-05-15 Brian Behlendorf <[email protected]> - - * : Updating original ZFS sources to build 89 which - includes the new write throttling changes plus support - for using ZFS as your root device. Neither of which - will work exactly right without some more work but this - gets us much closers to the latest source. - - -2008-02-28 Brian Behlendorf <[email protected]> - - * : First attempt based on SPL module and zfs-lustre sources |
