Split spl-build.m4 Split the kernel interface configure checks in to seperate m4 macro files. This is intended to facilitate moving the spl source code in to the zfs repository. Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #682

Linux compat: Minimum kernel version 3.10 Increase the minimum supported kernel version from 2.6.32 to 3.10. This removes support for the following Linux enterprise distributions. Distribution | Kernel | End of Life ---------------- | ------ | ------------- Ubuntu 12.04 LTS | 3.2 | Apr 28, 2017 SLES 11 | 3.0 | Mar 32, 2019 RHEL / CentOS 6 | 2.6.32 | Nov 30, 2020 The following changes were made as part of removing support. * Updated `configure` to enforce a minimum kernel version as specified in the META file (Linux-Minimum: 3.10). configure: error: *** Cannot build against kernel version 2.6.32. *** The minimum supported kernel version is 3.10. * Removed all `configure` kABI checks and matching C code for interfaces which solely predate the Linux 3.10 kernel. * Updated all `configure` kABI checks to fail when an interface is missing which was in the 3.10 kernel up to the latest 5.1 kernel. Removed the HAVE_* preprocessor defines for these checks and updated the code to unconditionally use the verified interface. * Inverted the detection logic in several kABI checks to match the new interface as it appears in 3.10 and newer and not the legacy interface. * Consolidated the following checks in to individual files. Due the large number of changes in the checks it made sense to handle this now. It would be desirable to group other related checks in the same fashion, but this as left as future work. - config/kernel-blkdev.m4 - Block device kABI checks - config/kernel-blk-queue.m4 - Block queue kABI checks - config/kernel-bio.m4 - Bio interface kABI checks * Removed the kABI checks for sops->nr_cached_objects() and sops->free_cached_objects(). These interfaces are currently unused. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #9566

Perform KABI checks in parallel Reduce the time required for ./configure to perform the needed KABI checks by allowing kbuild to compile multiple test cases in parallel. This was accomplished by splitting each test's source code from the logic handling whether that code could be compiled or not. By introducing this split it's possible to minimize the number of times kbuild needs to be invoked. As importantly, it means all of the tests can be built in parallel. This does require a little extra care since we expect some tests to fail, so the --keep-going (-k) option must be provided otherwise some tests may not get compiled. Furthermore, since a failure during the kbuild modpost phase will result in an early exit; the final linking phase is limited to tests which passed the initial compilation and produced an object file. Once everything has been built the configure script proceeds as previously. The only significant difference is that it now merely needs to test for the existence of a .ko file to determine the result of a given test. This vastly speeds up the entire process. New test cases should use ZFS_LINUX_TEST_SRC to declare their test source code and ZFS_LINUX_TEST_RESULT to check the result. All of the existing kernel-*.m4 files have been updated accordingly, see config/kernel-current-time.m4 for a basic example. The legacy ZFS_LINUX_TRY_COMPILE macro has been kept to handle special cases but it's use is not encouraged. master (secs) patched (secs) ------------- ---------------- autogen.sh 61 68 configure 137 24 (~17% of current run time) make -j $(nproc) 44 44 make rpms 287 150 Reviewed-by: Tony Hutter <hutter2@llnl.gov> Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #8547 Closes #9132 Closes #9341

Update build system and packaging Minimal changes required to integrate the SPL sources in to the ZFS repository build infrastructure and packaging. Build system and packaging: * Renamed SPL_* autoconf m4 macros to ZFS_*. * Removed redundant SPL_* autoconf m4 macros. * Updated the RPM spec files to remove SPL package dependency. * The zfs package obsoletes the spl package, and the zfs-kmod package obsoletes the spl-kmod package. * The zfs-kmod-devel* packages were updated to add compatibility symlinks under /usr/src/spl-x.y.z until all dependent packages can be updated. They will be removed in a future release. * Updated copy-builtin script for in-kernel builds. * Updated DKMS package to include the spl.ko. * Updated stale AUTHORS file to include all contributors. * Updated stale COPYRIGHT and included the SPL as an exception. * Renamed README.markdown to README.md * Renamed OPENSOLARIS.LICENSE to LICENSE. * Renamed DISCLAIMER to NOTICE. Required code changes: * Removed redundant HAVE_SPL macro. * Removed _BOOT from nvpairs since it doesn't apply for Linux. * Initial header cleanup (removal of empty headers, refactoring). * Remove SPL repository clone/build from zimport.sh. * Use of DEFINE_RATELIMIT_STATE and DEFINE_SPINLOCK removed due to build issues when forcing C99 compilation. * Replaced legacy ACCESS_ONCE with READ_ONCE. * Include needed headers for `current` and `EXPORT_SYMBOL`.
