* cppcheck: integrete cppcheckBrian Behlendorf2021-01-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove dependency on sharetab file and refactor sharing logicGeorge Wilson2020-07-137-865/+991
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | == Motivation and Context The current implementation of 'sharenfs' and 'sharesmb' relies on the use of the sharetab file. The use of this file is os-specific and not required by linux or freebsd. Currently the code must maintain updates to this file which adds complexity and presents a significant performance impact when sharing many datasets. In addition, concurrently running 'zfs sharenfs' command results in missing entries in the sharetab file leading to unexpected failures. == Description This change removes the sharetab logic from the linux and freebsd implementation of 'sharenfs' and 'sharesmb'. It still preserves an os-specific library which contains the logic required for sharing NFS or SMB. The following entry points exist in the vastly simplified libshare library: - sa_enable_share -- shares a dataset but may not commit the change - sa_disable_share -- unshares a dataset but may not commit the change - sa_is_shared -- determine if a dataset is shared - sa_commit_share -- notify NFS/SMB subsystem to commit the shares - sa_validate_shareopts -- determine if sharing options are valid The sa_commit_share entry point is provided as a performance enhancement and is not required. The sa_enable_share/sa_disable_share may commit the share as part of the implementation. Libshare provides a framework for both NFS and SMB but some operating systems may not fully support these protocols or all features of the protocol. NFS Operation: For linux, libshare updates /etc/exports.d/zfs.exports to add and remove shares and then commits the changes by invoking 'exportfs -r'. This file, is automatically read by the kernel NFS implementation which makes for better integration with the NFS systemd service. For FreeBSD, libshare updates /etc/zfs/exports to add and remove shares and then commits the changes by sending a SIGHUP to mountd. SMB Operation: For linux, libshare adds and removes files in /var/lib/samba/usershares by calling the 'net' command directly. There is no need to commit the changes. FreeBSD does not support SMB. == Performance Results To test sharing performance we created a pool with an increasing number of datasets and invoked various zfs actions that would enable and disable sharing. The performance testing was limited to NFS sharing. The following tests were performed on an 8 vCPU system with 128GB and a pool comprised of 4 50GB SSDs: Scale testing: - Share all filesystems in parallel -- zfs sharenfs=on <dataset> & - Unshare all filesystems in parallel -- zfs sharenfs=off <dataset> & Functional testing: - share each filesystem serially -- zfs share -a - unshare each filesystem serially -- zfs unshare -a - reset sharenfs property and unshare -- zfs inherit -r sharenfs <pool> For 'zfs sharenfs=on' scale testing we saw an average reduction in time of 89.43% and for 'zfs sharenfs=off' we saw an average reduction in time of 83.36%. Functional testing also shows a huge improvement: - zfs share -- 97.97% reduction in time - zfs unshare -- 96.47% reduction in time - zfs inhert -r sharenfs -- 99.01% reduction in time Reviewed-by: Matt Ahrens <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Bryant G.

* Support -fsanitize=address with --enable-asanBrian Behlendorf2018-01-101-5/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When --enable-asan is provided to configure then build all user space components with fsanitize=address. For kernel support use the Linux KASAN feature instead. https://github.com/google/sanitizers/wiki/AddressSanitizer When using gcc version 4.8 any test case which intentionally generates a core dump will fail when using --enable-asan. The default behavior is to disable core dumps and only newer versions allow this behavior to be controled at run time with the ASAN_OPTIONS environment variable. Additionally, this patch includes some build system cleanup. * Rules.am updated to set the minimum AM_CFLAGS, AM_CPPFLAGS, and AM_LDFLAGS. Any additional flags should be added on a per-Makefile basic. The --enable-debug and --enable-asan options apply to all user space binaries and libraries. * Compiler checks consolidated in always-compiler-options.m4 and renamed for consistency. * -fstack-check compiler flag was removed, this functionality is provided by asan when configured with --enable-asan. * Split DEBUG_CFLAGS in to DEBUG_CFLAGS, DEBUG_CPPFLAGS, and DEBUG_LDFLAGS. * Moved default kernel build flags in to module/Makefile.in and split in to ZFS_MODULE_CFLAGS and ZFS_MODULE_CPPFLAGS. These flags are set with the standard ccflags-y kbuild mechanism. * -Wframe-larger-than checks applied only to binaries or libraries which include source files which are built in both user space and kernel space. This restriction is relaxed for user space only utilities. * -Wno-unused-but-set-variable applied only to libzfs and libzpool. The remaining warnings are the result of an ASSERT using a variable when is always declared. * -D_POSIX_PTHREAD_SEMANTICS and -D__EXTENSIONS__ dropped because they are Solaris specific and thus not needed. * Ensure $GDB is defined as gdb by default in zloop.sh.

* Fix nfs snapdir automountChunwei Chen2017-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The current implementation for allowing nfs to access snapdir is very buggy. It uses a special fh for snapdirs, such that the next time nfsd does fh_to_dentry, it actually returns the root inode inside the snapshot. So nfsd never knows it cross a mountpoint. The problem is that nfsd will not hold a reference on the vfsmount of the snapshot. This cause auto unmounter to unmount the snapshot even though nfs is still holding dentries in it. To fix this, we return the inode for the snapdirs themselves. However, we also trigger automount upon fh_to_dentry, and return ESTALE so nfsd will revalidate and see the mountpoint and do crossmnt. Because nfsd will now be aware that these are different filesystems users must add crossmnt to their export options to access snapshot directories.
