+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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.

+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
+
+ * : 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 <behlendorf1@llnl.gov>
