* Fix Linux kernel directories detectionDamian Szuberski2022-02-161-30/+75
| | | | | | | | | | | | | | | | | | | | | | | | | Most modern Linux distributions have separate locations for bare source and prebuilt ("build") files. Additionally, there are `source` and `build` symlinks in `/lib/modules/$(KERNEL_VERSION)` pointing to them. The order of directory search is now: - `configure` command line values if both `--with-linux` and `--with-linux-obj` were defined - If only `--with-linux` was defined, `--with-linux-obj` is assumed to have the same value as `--with-linux` - If neither `--with-linux` nor `--with-linux-obj` were defined autodetection is used: - `/lib/modules/$(uname -r)/{source,build}` respectively, if exist - The first directory in `/lib/modules` with the highest version number according to `sort -V` which contains `source` and `build` symlinks/directories - The first directory matching `/usr/src/kernels/*` and `/usr/src/linux-*` with the highest version number according to `sort -V`. Here the source and prebuilt directories are assumed to be the same. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: szubersk <[email protected]> Closes #9935 Closes #13096

* Add support for $KERNEL_{CC,LD,LLVM} variablesPeter Levine2022-02-091-1/+7
| | | | | | | | | | | | | | | | | | Currently, $(CC), $(LD), and $(LLVM) variables aren't passed to kbuild while building modules. This causes modules to build with the default GNU GCC toolchain and prevents experimenting with other toolchains such as CLANG/LLVM. It can also lead to build failure if the CFLAGS/LDFLAGS passed are incompatible with gcc/ld. Pass $KERNEL_CC, $KERNEL_LD, and $KERNEL_LLVM as $(CC), $(LD), and $(LLVM), respectively, to kbuild for each that is defined in the environment. This should take care of the majority of alternative toolchain use cases.

* Linux 5.16 compat: don't use XSTATE_XSAVE to save FPU stateAttila Fülöp2022-02-092-2/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | | Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach, so add our own XSAVE{,OPT,S} code and use it for Linux 5.16. Please note that this differs from previous behavior in that it won't handle exceptions created by XSAVE an XRSTOR. This is sensible for three reasons. - Exceptions during XSAVE and XRSTOR can only occur if the feature is not supported or enabled or the memory operand isn't aligned on a 64 byte boundary. If this happens something else went terribly wrong, and it may be better to stop execution. - Previously we just printed a warning and didn't handle the fault, this is arguable for the above reason. - All other *SAVE instruction also don't handle exceptions, so this at least aligns behavior. Finally add a test to catch such a regression in the future.

* Add `--enable-asan` and `--enable-ubsan` switchesDamian Szuberski2022-02-034-1/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | `configure` now accepts `--enable-asan` and `--enable-ubsan` switches which results in passing `-fsanitize=address` and `-fsanitize=undefined`, respectively, to the compiler. Those flags are enabled in GitHub workflows for ZTS and zloop. Errors reported by both instrumentations are corrected, except for: - Memory leak reporting is (temporarily) suppressed. The cost of fixing them is relatively high compared to the gains. - Checksum computing functions in `module/zcommon/zfs_fletcher*` have UBSan errors suppressed. It is completely impractical to enforce 64-byte payload alignment there due to performance impact. - There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom memory allocator is used there rendering that measure unfeasible. - Memory leaks detection has to be suppressed for `cmd/zvol_id`. `zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is incompatible with memory leaks detection.

If not, then the attempt to override its internal call to bio_associate_blkg(), with a macro definition to our own version, is no longer possible, as the compiler won't use it when compiling the new inline function replacement implemented in the header. This change also creates a new vdev_bio_set_dev() function that performs the same work, and also performs the work implemented in vdev_bio_associate_blkg(), as it is the only thing calling that function in our code. Our custom vdev_bio_associate_blkg() is now only compiled if the bio_set_dev() is a macro in the Linux headers.

* Linux 5.13 compat: retry zvol_open() when contendedBrian Behlendorf2021-12-011-0/+22
| | | | | | | | | | | | | | | | | | | | | | | Due to a possible lock inversion the zvol open call path on Linux needs to be able to retry in the case where the spa_namespace_lock cannot be acquired. For Linux 5.12 an older kernel this was accomplished by returning -ERESTARTSYS from zvol_open() to request that blkdev_get() drop the bdev->bd_mutex lock, reaquire it, then call the open callback again. However, as of the 5.13 kernel this behavior was removed. Therefore, for 5.12 and older kernels we preserved the existing retry logic, but for 5.13 and newer kernels we retry internally in zvol_open(). This should always succeed except in the case where a pool's vdev are layed on zvols, in which case it may fail. To handle this case vdev_disk_open() has been updated to retry when opening a device when -ERESTARTSYS is returned.

| | | | | | | | | | | | | | | | | | | | | | The 5.15 kernel moved the backing_dev_info structure out of the request queue structure which causes a build failure. Rather than look in the new location for the BDI we instead detect this upstream refactoring by the existance of either the blk_queue_update_readahead() or disk_update_readahead() functions. In either case, there's no longer any reason to manually set the ra_pages value since it will be overridden with a reasonable default (2x the block size) when blk_queue_io_opt() is called. Therefore, we update the compatibility wrapper to do nothing for 5.9 and newer kernels. While it's tempting to do the same for older kernels we want to keep the compatibility code to preserve the existing behavior. Removing it would effectively increase the default readahead to 128k.

* Correct a flaw in the Python 3 version checkingRich Ercolani2021-06-082-6/+42
| | | | | | | | | | | | | | | It turns out the ax_python_devel.m4 version check assumes that ("3.X+1.0" >= "3.X.0") is True in Python, which is not when X+1 is 10 or above and X is not. (Also presumably X+1=100 and ...) So let's remake the check to behave consistently, using the "packaging" or (if absent) the "distlib" modules. (Also, update the Github workflows to use the new packages.)

* Introduce write-mostly sumsAlexander Motin2021-05-271-0/+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.
