2009-07-02 Brian Behlendorf * : Tag spl-0.4.4 * : Generic distro friendly build system / packaging improvements for RPM based distros including CHAOS, RHEL, Fedora, and SLES. spl-.src.rpm - Fully rebuildable source rpm for utils. spl-modules-.src.rpm - Fully rebuildable source rpm for kernel modules. spl-..rpm - Binary rpm for utils. The utils in this package are compatible with all spl-module rpms of the same version. spl-modules--.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--.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-, 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 * : 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_.x86_64.rpm spl-devel-x.y.2-1_.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. git log -35 2009-02-05 Brian Behlendorf * : 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 * : 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. 2008-11-26 Brian Behlendorf * : Tag spl-0.4.0 (Development now done with Git) * : Imported SPL SVN repo in to Git Repo for core development. 2008-11-26 Brian Behlendorf * : Tag spl-0.3.5 * : Include META file support. 2008-11-05 Jim Garlick * : 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 * 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. 2008-11-05 Brian Behlendorf * : Tag spl-0.3.4 * : Coverity clean. * : Patches from Ricardo M. Correia applied with minor revisions: spl-00-rm-gpl-symbol-notifier_chain.patch spl-01-rm-gpl-symbol-set_cpus_allowed.patch spl-02-rm-gpl-symbols-device.patch spl-03-rm-gpl-symbol-ktime_get_ts.patch spl-04-fix-taskq-spinlock-lockup.patch spl-05-div64.patch spl-06-atomic64.patch spl-07-kmem-cleanup.patch spl-08-km-sleep-nofail.patch spl-09-fix-kmem-track-oops.patch spl-10-fix-assert-verify-ndebug.patch 2008-06-30 Brian Behlendorf * : 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 * : 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 * : 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 * configure.ac, autoconf/* : Initial pass at resolving API changes introduced by kernels newer than 2.6.18. 2008-05-21 Brian Behlendorf * : Tag spl-0.3.1 * : License headers including URCL added for release. 2008-05-21 Brian Behlendorf * : Tag spl-0.3.0 * configure.ac: Improved autotools support. 2008-04-26 Brian Behlendorf * 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 * : Tag spl-0.2.1 * modules/spl/spl-proc.c : Add /proc/sys/spl/version. 2008-04-24 Herb Wartens * 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 * 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 : Initial commit of the solaris porting layer (spl). Included in addition to the source is an initial autoconf / configure style build system.
