* Introduce write-mostly sumsAlexander Motin2021-06-091-0/+27
| | | | | | | | | | | | | | | | | | | | | wmsum counters are a reduced version of aggsum counters, optimized for write-mostly scenarios. They do not provide optimized read functions, but instead allow much cheaper add function. The primary usage is infrequently read statistic counters, not requiring exact precision. The Linux implementation is directly mapped into percpu_counter KPI. The FreeBSD implementation is directly mapped into counter(9) KPI. In user-space due to lack of better implementation mapped to aggsum. Unfortunately neither Linux percpu_counter nor FreeBSD counter(9) provide sufficient functionality to completelly replace aggsum, so it still remains to be used for several hot counters.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for cppcheck to perform a proper analysis it needs to be aware of how the sources are compiled (source files, include paths/files, extra defines, etc). All the needed information is available from the Makefiles and can be leveraged with a generic cppcheck Makefile target. So let's add one. Additional minor changes: * Removing the cppcheck-suppressions.txt file. With cppcheck 2.3 and these changes it appears to no longer be needed. Some inline suppressions were also removed since they appear not to be needed. We can add them back if it turns out they're needed for older versions of cppcheck. * Added the ax_count_cpus m4 macro to detect at configure time how many processors are available in order to run multiple cppcheck jobs. This value is also now used as a replacement for nproc when executing the kernel interface checks. * "PHONY =" line moved in to the Rules.am file which is included at the top of all Makefile.am's. This is just convenient becase it allows us to use the += syntax to add phony targets. * One upside of this integration worth mentioning is it now allows `make cppcheck` to be run in any directory to check that subtree. * For the moment, cppcheck is not run against the FreeBSD specific kernel sources. The cppcheck-FreeBSD target will need to be implemented and testing on FreeBSD to support this.

* Linux 4.18.0-257.el8 compat: blk_alloc_queue()Brian Behlendorf2020-12-211-17/+56
| | | | | | | | | | | | | | | | | | | | | The CentOS stream 4.18.0-257 kernel appears to have backported the Linux 5.9 change to make_request_fn and the associated API. To maintain weak modules compatibility the original symbol was retained and the new interface blk_alloc_queue_rh() was added. Unfortunately, blk_alloc_queue() was replaced in the blkdev.h header by blk_alloc_queue_bh() so there doesn't seem to be a way to build new kmods against the old interfces. Even though they appear to still be available for weak module binding. To accommodate this a configure check is added for the new _rh() variant of the function and used if available. If compatibility code gets added to the kernel for the original blk_alloc_queue() interface this should be fine. OpenZFS will simply continue to prefer the new interface and only fallback to blk_alloc_queue() when blk_alloc_queue_rh() isn't available.

* Linux 5.10 compat: use iov_iter in uio structureBrian Behlendorf2020-12-182-0/+208
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of the 5.10 kernel the generic splice compatibility code has been removed. All filesystems are now responsible for registering a ->splice_read and ->splice_write callback to support this operation. The good news is the VFS provided generic_file_splice_read() and iter_file_splice_write() callbacks can be used provided the ->iter_read and ->iter_write callback support pipes. However, this is currently not the case and only iovecs and bvecs (not pipes) are ever attached to the uio structure. This commit changes that by allowing full iov_iter structures to be attached to uios. Ever since the 4.9 kernel the iov_iter structure has supported iovecs, kvecs, bvevs, and pipes so it's desirable to pass the entire thing when possible. In conjunction with this the uio helper functions (i.e uiomove(), uiocopy(), etc) have been updated to understand the new UIO_ITER type. Note that using the kernel provided uio_iter interfaces allowed the existing Linux specific uio handling code to be simplified. When there's no longer a need to support kernel's older than 4.9, then it will be possible to remove the iovec and bvec members from the uio structure and always use a uio_iter. Until then we need to maintain all of the existing types for older kernels. Some additional refactoring and cleanup was included in this change: - Added checks to configure to detect available iov_iter interfaces. Some are available all the way back to the 3.10 kernel and are used when available. In particular, uio_prefaultpages() now always uses iov_iter_fault_in_readable() which is available for all supported kernels. - The unused UIO_USERISPACE type has been removed. It is no longer needed now that the uio_seg enum is platform specific. - Moved zfs_uio.c from the zcommon.ko module to the Linux specific platform code for the zfs.ko module. This gets it out of libzfs where it was never needed and keeps this Linux specific code out of the common sources. - Removed unnecessary O_APPEND handling from zfs_iter_write(), this is redundant and O_APPEND is already handled in zfs_write(); Reviewed-by: Colin Ian King <[email protected]> Reviewed-by: Tony Hutter <[email protected]> Signed-off-by: Brian Behlendorf <[email protected]> Closes #11351

In file included from /home/fedora/zfs/build/objtool/objtool.c:75: ./arch/x86/include/asm/frame.h:100:57: error: 'struct pt_regs' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] The consequence of this is that the "stack_frame_non_standard" check is never run and HAVE_STACK_FRAME_NON_STANDARD is set incorrectly which results in a build failure. This change adds the appropriate header to the "objtool" check so it now behaves as intended.

* config/zfs-build.m4: never define _initramfs in RPM_DEFINE_UTILHarald van Dijk2020-09-123-6/+17
| | | | | | | | | | | | | | | | | | | The zfs-initramfs package has never worked as no RPM-based distribution uses initramfs-tools, which is listed as a dependency of zfs-initramfs. This would not ordinarily be a problem, as it is only enabled when /usr/share/initramfs-tools is present, which should not normally be the case on RPM-based distributions. However, other packages may install unused files there even if initramfs-tools is not used, so remove this auto-detection for the rpm-utils target. This does not fully remove the logic for the zfs-initramfs package. This splits it out into a separate rpm-utils-initramfs target so that the Debian builds can still use it.

| | | | | | | | | | | | Several of the listed library dependencies are not relevant on FreeBSD. Have ./configure save libraries that are found via pkg-config as ${LIB}_PC and use the configured automake variables instead of hard coded names so we only get what was actually needed.

* Linux 5.9 compat: NR_SLAB_RECLAIMABLEBrian Behlendorf2020-08-291-9/+0
| | | | | | | | | | | | | | | | | | | Commit dcdc12e added compatibility code to treat NR_SLAB_RECLAIMABLE_B as if it were the same as NR_SLAB_RECLAIMABLE. However, the new value is in bytes while the old value was in pages which means they are not interchangeable. The only place the reclaimable slab size is used is as a component of the calculation done by arc_free_memory(). This function returns the amount of memory the ARC considers to be free or reclaimable at little cost. Rather than switch to a new interface to get this value it has been removed it from the calculation. It is normally a minor component compared to the number of inactive or free pages, and removing it aligns the behavior with the FreeBSD version of arc_free_memory().

* config/zfs-build.m4: add --with-vendor flagGeorgy Yakovlev2020-08-281-27/+37
| | | | | | | | | | | | | | | | | | | | This will allow an override of auto-detection of distribution, which is based on checking presence of /etc/*-release files. Build systems makes a lot of file location assumptions based on detected distribution. Some distributions (like gentoo) may prefer explicitly setting --with-vendor=gentoo to avoid auto-detection. Since auto-detection checks all files in order, current script may misdetect even on gentoo system if /etc/redhat-release file is present Default behavior is unchanged and default is --with-vendor=check Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Georgy Yakovlev <[email protected]> Closes #10835
* Import ZStandard v1.4.5Michael Niewöhner2020-08-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | ZStandard is a modern, high performance, general compression algorithm. It provides similar or better compression levels to GZIP, but with much better performance. ZStandard provides a large selection of compression levels to allow a storage administrator to select the preferred performance/compression trade-off. This commit imports the unmodified ZStandard single-file library which will be used by ZFS. The implementation of this new library is done with future updates of zstd in mind. For this reason we integrated the code in a way, that does not require modifications to the library. For more details, see `module/zstd/README.md`. The library is excluded from codecov calculation and cppcheck as unaltered dependencies do not need full codecov or cppcheck.
