+
+ * : 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.
+

+
+ * : 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.
+

+
+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.

+
+ * : modules/sys/kmem-slab.c : Re-implemented the slab to no
