-
- * : Tag spl-0.4.9
-
- * : Build system improvements:
- - Added support for the 'make -s' silent build option.
- - Allow spl_config.h to be included by dependent packages.
- - Minor spec file updates.
-
- * AUTHORS, COPYING, DISCLAIMER, and INSTALL: Updated.
-
- * *.c, *.h, *.sh, AUTHORS, COPYING, DISCLAIMER, and INSTALL:
- 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.
-
- * module/spl/spl-debug.c: Debugging defaults adjusted. The default
- log dump path is now /tmp/spl-log and panic on SBUG has been disabled.
-
- * include/sys/processor.h, include/sys/systm.h, include/sys/types.h:
- Added 3 missing typedefs processorid_t, pc_t, and index_t.
-
- * include/sys/console.h: Added support for console_* functions().
-
- * module/spl/spl-time.c: Updated gethrtime() to use the function
- do_posix_clock_monotonic_gettime() as described in the comment.
-
- * module/spl/spl-condvar.c: Added cv_wait_interruptible() function
- as an extension to the existing condition variable ABI to enable
- sleeping threads a way to cleanly handle signals in the kernel.
-
- * module/spl/spl-debug.c: Dump log from current process as required.
-
- * module/spl/spl-taskq.c: Assume TQ_SLEEP in taskq_dispatch() if
- the caller does not specify, this is the Solaris default.
-
- * module/spl/spl-vnode.c: Extend the vn_rdwr() implementation to
- correctly handle the FAPPEND option.
-
- * module/spl/spl-generic.c, module/spl/spl-vnode.c: Update
- vn_set_pwd() to allow a kernal address as filename. This turns
- out to be critical because spl_setup()->The vn_set_pwd("/") which
- is called at module load time was failing with -EFAULT.
-
- * include/sys/rwlock.h: Disable rw_tryupgrade() for kernels built
- without CONFIG_RWSEM_GENERIC_SPINLOCK defined. The existing
- implementation is not safe in this case and needs to be replaced
- with a correct native per-arch implementation.
-
- * module/spl/spl-kmem.c: Reduce maximum kmem based slab size.
- Allowing MAX_ORDER-1 sized memory allocations while the system
- is low on memory has been observed to result in deadlocks. Callers
- should not be using the slab in this way but we should still handle
- the case more cleanly.
-
- * module/spl/spl-kmem.c: Remove kmem_set_warning() interface and
- replace it with KM_NODEBUG flag which can be specific per allocation.
-
- * module/splat/splat-kmem.c: Tweaked what the idea of a large object
- is for the kmem:slab_large regression tests because failures were
- observed for very large kmem objects in newer kernels.
-
- * include/sys/rwlock.h, module/splat/splat-rwlock.c: The rwlock
- implementation was simplified because failures were being observed
- when using the non-generic implementation. This change leverages
- the rwsem_is_locked() function instead of directly consulting the
- rwsem internals which differ per-arch and per-kernel-version.
-
-2010-03-11 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.8
-
- * : 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.
-
- * config/spl-build.m4: Linux 2.6.32 compat, SPL_AC_5ARGS_PROC_HANDLER
- macro added to handle updated proc_handler () API.
-
- * module/spl/spl-err.c: Fix panic() string, which was being used as a
- format string, instead of an already-formatted string.
-
- * /module/spl/spl-taskq.c: Optimize lowest outstanding taskqid
- calculation in taskq_lowest_id(). The motivation for this change
- was that I was observing as much as 10% of the total CPU time go
- to waiting on the tq->tq_lock when the pending list was long.
-
- * module/spl/spl-kmem.c: Strip __GFP_ZERO from kmalloc it is not
- available for older kernels.
-
- * module/spl/spl-proc.c: Add skc_flags and full header to
- /proc/spl/kmem/slab
-
- * module/spl/spl-generic.c: Correctly handle division on 32-bit RHEL5
- systems by returning dividend.
-
- * include/sys/rwlock.h: When using x86 specific rwsem correctly
- intepret rwsem->count. Additionally check for changed guard macro
- in 2.6.28+ for rwsem implementation
-
- * module/splat/splat-vnode.c, module/splat/splat-kmem.c,
- module/splat/splat-taskq.c: Several new tests were added to the
- test suite and various bug fixes.
-
- * include/asm/atomic_compat.h: Atomic64 compatibility for 32-bit
- systems without kernel support.
-
- * .gitignore: Added .gitignore files.
-
-2009-11-20 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.7
-
- * config/spl-build.m4: Linux 2.6.31 compat, SPL_AC_2ARGS_SET_FS_PWD
- macro updated to explicitly include linux/fs_struct.h which was
- dropped from linux/sched.h.
-
- * include/linux/mm_compat.h: Linux 2.6.31 compat, use the macros
- min_wmark_pages, low_wmark_pages, and high_wmark_pages which were
- introduced. For older kernels a compability macro is used.
-
- * include/sys/kmem.h: Linux 2.6.31 compat, the __GFP_NOFAIL flag
- should no longer be used and it may disappear from the kernel at any
- time. To handle this I have simply added *_nofail wrappers in the
- kmem implementation which perform the retry for non-atomic allocations.
-
- * module/spl/spl-kmem.c: Linux 2.6.31 compat, kmem cache alignment
- fixes and cleanup. Always perform allocations for the kmem cache
- using __get_free_pages() or __vmalloc() to ensure the returned
- memory is page aligned. Also introduce helper functions which use
- P2ROUNDUP_TYPE instead of P2ROUNDUP force all types to be explicit.
-
- * include/sys/mutex.h: Add mutex_enter_nested() as wrapper for
- mutex_lock_nested() to permit integration with the lock checker.
-
- * include/sys/mutex.h: Always use the generic mutex_destroy().
-
- * Makefile.am: Ensure *.order and *.markers build products are
- removed by distclean rule.
-
-2009-11-02 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.6
-
- * config/spl-build.m4: Cleanup --enable-debug-* configure options.
- --enable-debug=<default no> generic debug support.
- --enable-debug-kmem=<default yes> basic kmem and slab accounting.
- --enable-debug-kmem-tracking=<default no> detailed kmem tracking.
- --enable-debug-kstat removed option support always enabled.
- --enable-debug-callb removed option which never did anything.
-
- * module/spl/spl-atomic.c: Reimplemented atomic functions by
- layering them on top of the Linux atomic functions. This improves
- performance by removing the need for a global spinlock.
-
- * module/spl/spl-debug.c: Rebase cmn_err on vcmn_err. Handle the
- case where the message contains a leading ! which means only send
- it to syslog. And suppress warnings for messages which do not end
- in a '\n'.
-
- * module/splat/splat-ctl.c: Update to use kobject_set_name() for
- increased portability.
-
- * module/spl/spl-generic.c: Set cwd to '/' for the task during
- module load for SPL dependent modules. Under Solaris this is
- the expected behavior, on a Linux system your cwd remains set
- to whatever the tasks cwd was when loading a module.
-
- * module/spl/spl-mutex.c: Reimplemented mutexs for improved
- performance and cleaner integration with the Linux kernels built
- in lock analyzer. As of 2.6.29 based kernels adaptive mutexs
- are supported, for these newer kernels task_curr() does not need
- to be exported. Finally, DEBUG_MUTEX support was dropped in
- favor of more detailed kernel profiling which is now available.
-
- * module/spl/spl-rwlock.c: Reimplemented rwlocks for improved
- performance and cleaner integration with the Linux kernels built
- in lock analyzer. Additionally, the rwlock regression tests were
- improved to help validate correctness.
-
- * spl-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 spl-0.4.5
-
- * FC11 and SLES11 support: This includes all compatibility changes
- to support 2.6.29 based kernels and the required build system
- improvements.
- * module/spl/spl-module.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.
- * config/spl-build.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.
- * module/spl/spl-vnode.: Use HAVE_PATH_IN_NAMEIDATA compat macros
- for maximum kernel compatibility.
- * config/spl-build.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.
- * include/sys/vmsystm.h, module/spl/spl-kmem.c: Perferentially use the
- global_page_state() API when your kernel supports the required enums.
- * include/sys/debug.h: Add ASSERTV macro to simplify removing
- variables (the V in ASSERTV) which are only used in ASSERT().
- * include/sys/debug.h: Disable stack overflow checking by default
- when build with --enable-debug, modern kernels now provide this.
- * patches/fc11-spl-export-symbols.patch: Recommended missing symbols
- patch for FC11. This is not required for correct functionality but
- it is recommended for individuals who are already patching the kernel.
-
- * Additional Solaris API emulation:
- * include/sys/taskq.h: Add basic taskq support for the flag
- TASKQ_THREADS_CPU_PCT which is used to scale the number of threads
- based on the number of online CPUs.
- * include/sys/file.hi, module/spl/spl-generic.c: Add support for
- fake ioctls which originate from the kernel instead of user space.
- * include/sys/acl.h: Add ACE_ALL_PERMS ACL definition.
- * include/sys/cred.h, module/splat/splat-cred.c: Add basic credential
- support and splat regression tests.
-
- * Bug fixes:
- * include/sys/isa_defs.h: Add more endianess paranoia.
- * module/spl/spl-time.c: Integer overflow after ~164 days.
- * include/sys/debug.h: NULL dereference by tcd_for_each().
- * module/splat/splat-kmem.c: Allow kmem or vmem based slabs for
- slab_lock and slab_overcommit tests. This may still be an issue on
- 32-bit systems due to the small virtual address space.
- * module/spl/spl-module.c: Positive Solaris ioctl return codes are
- need to be negated for use by libc to ensure errno is set correctly.
-
-2009-07-02 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.4
-
- * : Generic distro friendly build system / packaging improvements
- for rpm based distros including CHAOS, RHEL, Fedora, and SLES.
-
- spl-<version>.src.rpm
- - Fully rebuildable source rpm for utils.
- spl-modules-<version>.src.rpm
- - Fully rebuildable source rpm for kernel modules.
-
- spl-<version>.<arch>.rpm
- - Binary rpm for utils. The utils in this package are compatible
- with all spl-module rpms of the same version.
-
- spl-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.
- spl-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
- spl module.
-
- * : Added SLES10 support. This includes all compatibility
- changes to support 2.6.16 based kernels and the required
- build system improvements.
-
- * : Build System changes for SLES10:
- - Exclude -obj when detecting installed kernel source.
- - Detect -obj directory for out of tree kernel builds.
- - Allow kernel build system to set CC to ensure -m64 is set properly.
- This is an issue on 64-bit SLES systems which by default always
- build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit)
-
- * : Configure Checks added for SLES10:
- - div64_64() renamed to div64_u64() as of 2.6.26.
- - global_page_state() fuction was introduced in 2.6.18 kernels.
- The earlier 2.6.16 based SLES10 must not try and use it,
- thankfully get_zone_counts() is still available.
- - monotonic_clock() is unavailable __gethrtime() must perform the
- HZ division as an 'unsigned long long' because the SPL only
- implements __udivdi3(), and not __divdi3() for 'long long'
- division on 32-bit arches.
- - mutex_lock_nested() was introduced as part of the mutex
- validator in 2.6.18, when it is unavailable it is safe to
- fallback to using a plain mutex_lock().
- - SLES specific API change to vfs_unlink() and vfs_rename() which
- added a 'struct vfsmount *' argument. This was for something
- called the linux-security-module, but it appears that it was
- never adopted upstream.
- - spl_device_create() correctly mapped to class_device_create()
- for 2.6.13 to 2.6.17 based kernels, this is the preferred API.
- - Prior to 2.6.17 there were no *_pgdat helper functions in
- mm/mmzone.c. Instead for_each_zone() operated directly on
- pgdat_list which may or may not have been exported depending on
- how your kernel was compiled. A configure check was added to
- determine if you have the helpers or not, and if the needed
- symbols are exported. If they are not exported then they are
- dynamically aquired at runtime by kallsyms_lookup_name().
-
- * : Packaging changes for SLES10
- - Properly honor --prefix in build system and rpm spec file.
- - Add '--define require_kdir' to spec file to support building
- rpms against kernel sources installed in non-default locations.
- - Add '--define require_kobj' to spec file to support building
- rpms against kernel object installed in non-default locations.
- - Stop suppressing errors in autogen.sh script.
- - Improved logic to detect missing kernel objects when they are
- not located with the source. This is the common case for SLES
- as well as in-tree chaos kernel builds and is done to simply
- support for multiple arches.
- - Moved spl-devel build products to /usr/src/spl-<version>, a
- spl symlink is created to reference the last installed version.
- - Allow checking for exported symbols in both Module.symvers
- and Module.symvers. My stock SLES kernel ships an objects
- directory with Module.symvers, yet produces a Module.symvers
- in the local build directory.
-
- * : Added powerpc64 support.
- - Enable builds for powerpc64 ISA type.
- - Add DIV_ROUND_UP and roundup macros if unavailable.
- - Cast 64-bit values for %lld format string to (long long) to
- quiet compile warning.
-
- * module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary
- compatibility. We need to ensure the ioctl data itself is always
- packed the same for 32/64-bit binaries. Additionally, the correct
- thing to do is encode this size in bytes as part of the command
- using _IOC_SIZE().
-
- * modules/spl/spl-kmem.c: Fixed a long standing bug in the debug
- tracing. The tcd_for_each() macro expected a NULL to terminate
- the trace_data[i] array but this was only ever true due to luck.
- All trace_data[] iterators are now properly capped by TCD_TYPE_MAX.
-
- * modules/spl/spl-kmem.c: To simplify debugging all symbols aquired
- dynamically using spl_kallsyms_lookup_name() are initially poisoned
- with SYMBOL_POISON.
-
-2009-03-20 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.3
-
- * 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 spl-x.y.z-1.src.rpm
-
- This will produce two binary RPMs with correct 'requires'
- dependencies for your kernel. One will contain all zpl modules
- and support utilities, the other is a devel package for compiling
- additional kernel modules which are dependent on the spl.
-
- spl-x.y.z-1_<kernel version>.x86_64.rpm
- spl-devel-x.y.2-1_<kernel version>.x86_64.rpm
-
- * : FC10 (linux-2.6.27.19) and i686 compatibility update. The
- list of support platforms has been extended to include FC10
- systems and x86 architectures. It should be noted that kernels
- older the 2.6.27.19 should work but have not have not been tested.
-
- * configure.ac: Fix build issue preventing spl_config.h from being
- cleanly included by dependent packages.
-
- * module/spl/spl-taskq.c: Fix taskq_wait() not waiting bug.
-
- * module/spl/spl-xdr.c: Add XDR implementation provided by Ricardo
- Correia from Sun.
-
- * module/spl/spl-kmem.c: Linux VM integration cleanup.
-
- * module/spl/spl-kmem.c: Slab cache improvements and fixes.
-
- * modules/splat/*: Include additional SPLAT regression tests.
-
- * : Various bug fixes are more clearly detailed in the git
- commit logs. For a detailed summary of changes post version
- 0.4.2 check the git commit logs.

-
- * : Tag spl-0.4.2
-
- * module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements:
- - Implement kmem cache alignment.
- - Implement slab ageing.
- - Optimized slab packing algorithm.
- - Fixed deadlock due to calling call kv_free() under the skc_lock.
- - Added additional SPLAT test cases
- - Performance optimizations
-
- * module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration.
- The Solaris global VM symbols minfree, desfree, lotsfree, needfree,
- swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are
- now available and loosely integrating with the Linux VM. Some
- tuning will undoubtably be needed and these tunables are available
- in /proc/sys/kernel/spl/vm/* for this very reason.
-
- * config/spl-build.m4: New configure checks needed when building
- against 2.6.27+ kernels. More work is needed here.
-
- * : Minor cleanup see the 'git log' for full details.
-
-2009-01-21 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.4.1
-
- * : Implement ksid_*, ddi_strto*, and system taskq functionality.
- In addition, several other small Solaris compatibility changes
- were made, see the 'git log' for full details.

- * : Imported SPL SVN repo in to Git Repo for core development.
-
-2008-11-26 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.3.5
-
- * : Include META file support.
-
-2008-11-05 Jim Garlick <garlick@llnl.gov>
-
- * : Add autogen.sh products.
-
- * configure.ac : Use AC_CONFIG_AUX_DIR to put autograph products
- in ./auotconf.
-
- * autogen.sh : Use --copy to avoid symlinks, remove error
- redirection, run aclocal before libtoolize.
-
-2008-11-13 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * include/sys/sunddi.h, modules/spl/spl-module.c : Removed default
- udev support from sunddi implementation because it uses GPL-only
- symbols. This support is optionally available for SPL consumers
- if they define HAVE_GPL_ONLY_SYMBOLS and license their module as
- GPL using the MODULE_LICENSE("GPL") macro.

-
- * : Tag spl-0.3.3
-
- * : modules/sys/kmem-slab.c : Refined SPL slab to include
- per-cpu caches, removed internal hash, other general
- performance improvements. Much work remain but it's pretty
- good for an initial implementation.
-
-2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : modules/sys/kmem-slab.c : Re-implemented the slab to no
- longer be based on the linux slab but to be it's own complete
- implementation. The new slab behaves much more like the
- Solaris slab than the Linux slab.
-
-2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-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.
-
-2008-05-25 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * configure.ac, autoconf/* : Initial pass at resolving
- API changes introduced by kernels newer than 2.6.18.
-
-2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.3.1
-
- * : License headers including URCL added for release.
-
-2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.3.0
-
- * configure.ac: Improved autotools support.
-
-2008-04-26 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * include/sys/mutex.h : Implemented a close approximation
- of adaptive mutexes. These changes however required me to
- export a new symbol from the kernel proper 'task_curr()'
- which means we are now dependant on a patched kernel.
-
-2008-04-24 Brian Behlendorf <behlendorf1@llnl.gov>
-
- * : Tag spl-0.2.1
-
- * modules/spl/spl-proc.c : Add /proc/sys/spl/version.
-
-2008-04-24 Herb Wartens <wartens2@llnl.gov>
-
- * include/sys/kmem.h : Make sure that when calling __vmem_alloc
- that we do not have __GFP_ZERO set. Once the memory is allocated
- then zero out the memory if __GFP_ZERO is passed to
- __vmem_alloc.
-
-2008-04-16 Herb Wartens <wartens2@llnl.gov>
-
- * modules/spl/spl-kmem.c : Make sure to disable interrupts
- when necessary to avoid deadlocks. We were seeing the deadlock
- when calling kmem_cache_generic_constructor() and then an interrupt
- forced us to end up calling kmem_cache_generic_destructor()
- which caused our deadlock.
-
-2008-02-26 Brian Behlendorf <behlendorf1@llnl.gov>
-
- : Initial commit of the solaris porting layer (spl). Included
- in addition to the source is an initial autoconf / configure
- style build system.
