* Linux 6.11: enable queue flush through queue limitsRob Norris2024-08-221-0/+21
| | | | | | | | | | | | | | | | | In 6.11 struct queue_limits gains a 'features' field, where, among other things, flush and write-cache are enabled. Detect it and use it. Along the way, the blk_queue_set_write_cache() compat wrapper gets a little cleanup. Since both flags are alway set together, its now a single bool. Also the very very ancient version that sets q->flush_flags directly couldn't actually turn it off, so I've fixed that. Not that we use it, but still.

* find_system_library: fix var cleanup when library not foundRob Norris2024-07-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "not found" path is attempting to clear SOMELIB_CFLAGS and SOMELIB_LIBS by resetting them in AC_SUBST(). However, the second arg to AC_SUBST is expanded in autoconf with `m4_ifvaln([$2], [[$1]=$2])`, which is defined as "if the first arg is non-empty". The m4 "empty" construction is [], therefore, the existing AC_SUBST calls never modify the variables at all. The effect of this is that leftovers from the library test can leak out. At least, if a library header is found in the first stage, but the library itself is not, -lsomelib is added to SOMELIB_LIBS and further tests done. If that library is not found, SOMELIB_LIBS will not be cleared. For most of our library tests this hasn't been a problem, as they're either always found properly via pkg-config or set directly, or the calling test immediately aborts configure. For an optional dependency however, an apparent "partial" result where the header is found but no corresponding library causes link errors later. I think a complete fix should probably not be setting SOMELIB_xxx until the final result is known, but for now, adjusting the AC_SUBST calls to explictly set the empty shell string (which is not "empty" to m4) at least restores the intent.

* Linux 6.10: rework queue limits setupRob Norris2024-07-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Linux has started moving to a model where instead of applying block queue limits through individual modification functions, a complete limits structure is built up and applied atomically, either when the block device or open, or some time afterwards. As of 6.10 this transition appears only partly completed. This commit matches that model within OpenZFS in a way that should work for past and future kernels. We set up a queue limits structure with any limits that have had their modification functions removed. For newer kernels that can have limits applied at block device open (HAVE_BLK_ALLOC_DISK_2ARG), we have a conversion function to turn the OpenZFS queue limits structure into Linux's queue_limits structure, which can then be passed in. For older kernels, we provide an application function that just calls the old functions for each limit in the structure.

| | | | | | | | | | | | | | | | | | | | | | Let Debian use the sysv-rc variant of the script, even when OpenRC is installed. Unlike on Gentoo, OpenRC on Debian consumes both the sysv-rc scripts and OpenRC ones. ZFS initscripts on Debian should be the sysv-rc version to provide most compatibility and to integrate with the rest of initscripts for dependency tracking. Restrict the substitution in the Makefile to the dedicated list. This construct is inspired by Mo Zhou's detection of the execution shell and follows the strategy of Peter in 6ef28c526ba7.

* vdev_disk: ensure trim errors are returned immediatelyRob N2024-04-111-33/+85
| | | | | | | | | | | | | | | | | | | | | | | After 08fd5ccc3, the discard issuing code was organised such that if requesting an async discard or secure erase failed before the IO was issued (that is, calling __blkdev_issue_discard() returned an error), the failed zio would never be executed, resulting in txg_sync hanging forever waiting for IO to finish. This commit fixes that by immediately executing a failed zio on error. To handle the successful synchronous op case, we fake an async op by, when not using an asynchronous submission method, queuing the successful result zio as part of the discard handler. Since it was hard to understand the differences between discard and secure erase, and sync and async, across different kernel versions, I've commented and reorganised the code a bit to try and make everything more contained and linear.

| | | | | | | | | | | | | | | | | | | | The LLVM/Clang developers pointed out that using the CPP to detect use of functions that our QA policies prohibit risks invoking undefined behavior. To resolve this, we configure CodeQL to detect forbidden function usage. Note that cpp in the context of CodeQL refers to C/C++, rather than the C PreProcessor, which C++ also uses. It really should have been written cxx, but that ship sailed a long time ago. This misuse of the term cpp is retained in the CodeQL configuration for consistency with upstream CodeQL. As a side benefit, verbose make no longer is a wall of text showing a bunch of CPP macros, which can make debugging slightly easier.

* contrib: bash_completion.d: make install destination vendor dependentStoiko Ivanov2023-10-031-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain Linux distributions (Debian/Ubuntu at least) expect bash-completion snippets to be installed in /usr/share/bash-completion/completions instead of /etc/bash_completion.d. This patch sets the bashcompletiondir variable based on the vendor, inspired by similar settings for initdir and initconfdir. It seems that commit 612b8dff5bc3d827efb864a199a62bda1a419254 caused the file to be installed in the first-place (thus the error when building debian packages only became apparent when testing a 2.2.0-rc4 build) The change only sets the variable in Makefile context - the rpm/zfs.spec.in file has the path hardcoded as %{_sysconfdir}/bash_completion.d/zfs, but since running ``` ./configure --sysconfdir=/myetc ; make rpm ``` also results in all relevant files to be installed in /etc instead of /myetc I assume this can remain as is.

* Linux 6.5 compat: Use copy_splice_read instead of filemap_splice_readColeman Kane2023-09-192-11/+11
| | | | | | | | | | | Using the filemap_splice_read function for the splice_read handler was leading to occasional data corruption under certain circumstances. Favor using copy_splice_read instead, which does not demonstrate the same erroneous behavior under the tested failure cases.

* Linux 6.5 compat: replace generic_file_splice_read with filemap_splice_readColeman Kane2023-09-193-2/+28
| | | | | | | | | | | | | | | | The generic_file_splice_read function was removed in Linux 6.5 in favor of filemap_splice_read. Add an autoconf test for filemap_splice_read and use it if it is found as the handler for .splice_read in the file_operations struct. Additionally, ITER_PIPE was removed in 6.5. This change removes the ITER_* macros that OpenZFS doesn't use from being tested in config/kernel-vfs-iov_iter.m4. The removal of ITER_PIPE was causing the test to fail, which also affected the code responsible for setting the .splice_read handler, above. That behavior caused run-time panics on Linux 6.5.

* Linux 6.5 compat: register_sysctl_table removedColeman Kane2023-09-192-0/+29
| | | | | | | | | | | | | | Additionally, the .child element of ctl_table has been removed in 6.5. This change adds a new test for the pre-6.5 register_sysctl_table() function, and uses the old code in that case. If it isn't found, then the parentage entries in the tables are removed, and the register_sysctl call is provided the paths of "kernel/spl", "kernel/spl/kmem", and "kernel/spl/kstat" directly, to populate each subdirectory over three calls, as is the new API.
