2023-02-25generic: add test for direct io partial writesBoris Burkov
btrfs recently had a bug where a direct io partial write resulted in a hole in the file. Add a new generic test which creates a 2MiB file, mmaps it, touches the first byte, then does an O_DIRECT write of the mmapped buffer into a new file. This should result in the mapped pages being a mix of in and out of page cache and thus a partial write, for filesystems using iomap and IOMAP_DIO_PARTIAL.

The read operation triggers page faults when accessing all pages of the read buffer except for the pages corresponding to the first extent. We want to check that the operation results in reading all the extents and that it returns the correct data. This is motivated by an issue found with MariaDB when using io_uring and running on btrfs.

Add test checking functionality of seekdir. We check whether seekdir gets us back to the directory entry it should and also whether seeking to random positions does not crash the filesystem. Unlike test generic/310 which also tests seeking, this test checks both glibc readdir() function as well as getdents64() syscall directly. This is because glibc readdir() implementation does a lot of caching and processing internally thus hiding kernel from some possible problems. Also test wider range of random offsets to have better chance of hitting out of bound accesses or other bugs.

Regression test to verify that creating a series of detached mounts, attaching them to the filesystem, and unmounting them does not trigger an integer overflow in ns->mounts causing the kernel to block any new mounts in count_mounts() and returning ENOSPC because it falsely assumes that the maximum number of mounts in the mount namespace has been reached, i.e. it thinks it can't fit the new mounts into the mount namespace anymore. The test is written in a way that it will leave the host's mount namespace intact so we are sure to never make the host's mount namespace unuseable!

2018-04-27generic: test record locks across execve in multithread processXiong Zhou
POSIX requires that record locks are preserved across an execve(2). But currently the locks are released if process is multithreaded at the time that execve is called. As Jeff Layton wrote in his patch: " In that case, we'll end up unsharing the files_struct but the locks will still have their fl_owner set to the address of the old one. Eventually, when the other threads die and the last reference to the old files_struct is put, any POSIX locks get torn down since it looks like a close occurred on them. The result is that all of your open files will be intact with none of the locks you held before execve. " Add a new regression test for this particular case.

2018-02-16generic: add OFD lock testsXiong Zhou
Test OFD locks. Use fcntl F_OFD_SETLK/F_OFD_GETLK, to verify we are being given correct advices through getlk by kernel. The basic idea is one setlk routine setting locks via fcntl *_SETLK, followed by operations like clone, dup then close fd; another routine getlk getting locks via fcntl *_GETLK. Firstly in setlk routine process P0, place a lock L0 on an opened testfile, then do clone or dup and close relative fd. In getlk process P2, do fcntl *_GETLK with lock L1 after get notified by setlk routine. In the end, getlk routine check the returned struct flock.l_type to see if the lock mechanism works fine. Test combainations of: - shared or exclusive lock - these locks are conflicting or not - one OFD lock and one POSIX lock - that open testfile RDONLY or RDWR - clone with CLONE_FILES or not - dup and close newfd [eguan: made some minor non-functional changes] Signed-off-by: Xiong Zhou <xzhou@redhat.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

Add a regression test for the following kernel commit: ext4: prevent data corruption with inline data + DAX The test passes either if we don't encounter corruption, or if mounting with DAX + inline data fails. The latter is the way that we prevent this issue in the kernel.

2017-11-26fstests: add fio perf results supportJosef Bacik
This patch does the nuts and bolts of grabbing fio results and storing them in a database in order to check against for future runs. This works by storing the results in resuts/fio-results.db as a sqlite database. The src/perf directory has all the supporting python code for parsing the fio json results, storing it in the database, and loading previous results from the database to compare with the current results. This also adds a PERF_CONFIGNAME option that must be set for this to work. Since we all have various ways we run fstests it doesn't make sense to compare different configurations with each other (unless specifically desired). The PERF_CONFIGNAME will allow us to separate out results for different test run configurations to make sure we're comparing results correctly. Currently we only check against the last perf result. In the future I will flesh this out to compare against the average of N number of runs to be a little more complete, and hopefully that will allow us to also watch latencies as well.

2017-10-11generic: test race when checking i_size on direct i/o readZheng Liu
In this commit a new test case is added to test that i_size races don't occur under dio reads/writes. We add a program in /src dir, which has a writer to issue some append dio writes. Meanwhile it has a reader in this test to do some dio reads. As we expect, reader should read nothing or data with 'a'. But it might read some data with '0'. The bug can be reproduced by this test case [1]. 1. http://patchwork.ozlabs.org/patch/311761/ This ostensibly tests commit: 9fe55eea7 Fix race when checking i_size on direct i/o read Update by Eric Sandeen: - update to recent xfstests - update commit log Update by Eryu Guan: - add aio-dio support to the test and add 'aio' group - add ability to test different alignments - move test from src/ to src/aio-dio-regress/ - add .gitignore entry - rebase against latest xfstests with various minor fixes & cleanups - update commit log Reviewed-by: Brian Foster <bfoster@redhat.com> Signed-off-by: Zheng Liu <wenqing.lz@taobao.com> Signed-off-by: Eric Sandeen <sandeen@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
2017-10-09generic: add a new test for racing AIO COW writesChristoph Hellwig
This can be used to trigger an assert in the current XFS code because it can't handle the case where there are COW extents on a file, but none at or below the range converted by the AIO completion handler. Note that it doesn't trigger the assert 100% but fairly reliably. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Darrick J.
