Sorry, I should have mentioned that xfstests has been renamed to fstests in 2014[1], so they're the same thing.

That could be better advertised. A google search for "fstests" for example turns up mostly irrelevant results. And I can't recall anyone at LSF/MM meetings, for example, calling it anything other than "xfstests"? Anyway, thanks for adding this.

(Sorry for getting back to this late.) Yes, that's a problem, it's been 'xfstests' for at least 14 years and 'fstests' is only there for 3 years, sometimes (or most of the times) we still call it 'xfstests' for a better understanding. But at least this thread does 'advertise' fstests to NFS list, I guess :) > > Anyway, thanks for adding this. I do a partial fstests run as part of Can I take it as a "Reviewed-by" tag? :) > my regular testing but I'm not great about keeping it updated. fstests is updated weekly, but usually only one or two new tests (or none) are added in a update, so not keeping it up-to-date is not a big issue. Running existing tests would be good enough too. For a quick smoke test './check -nfs -g quick' (run tests in 'quick' group) will do, it only takes around 10 minutes for me to complete. And for something more thoroughly, you can do './check -nfs -g auto' (run tests in 'auto' group), which will take longer time but runs many more tests. I test every RC release with local-mounted NFS, with NFSv3, NFSv4.0/4.1/4.2. Here're the 'known issues' I have for 4.11 kernel (I think some failures are false alert, the tests need updates, some failures may long standing & low priority bugs on NFS? But I'm not sure which is which) Failures for all NFS versions: generic/035 test fail in rename syscall test, test reported "t_rename_overwrite: fstat(3): Stale file handle" generic/294 expect EEXIST not EROFS Failures for NFSv3 generic/258 NFSv3 does not support timestamp before epoch generic/375 sgid not cleared on setfacl, Permission denied Failures for NFSv4.0/4.1/4.2 generic/011 sometimes direstress test failed, rarely happened generic/401 NFSv4 reports . and .. dtype as unknown I use this 'local.config' file for fstests to test NFS, and update the 'vers=3' mount option as needed ----->8------ TEST_DEV=localhost:/mnt/nfsexport TEST_DIR=/mnt/testarea/test SCRATCH_DEV=localhost:/mnt/nfsscratch SCRATCH_MNT=/mnt/testarea/scratch TEST_FS_MOUNT_OPTS="-o vers=3" MOUNT_OPTIONS="-o vers=3" -----8<------ > > --b. > > > > > fstests does find NFS bugs (some are regression bugs), I noticed at least three > > > > regressions introduced in 4.12-rc1 release, one was reported to nfs list[1].

Just to troll slightly: I actually don't believe you when you say it's been renamed. I don't see any evidence of that. The repository still seems to be called xfstests-dev, the README calls it "the FSQA suite" or "xfstests", with only a brief mention of the fstest mailing list at the end. In fact that's the only use of the term "fstests" in the entire repository: $ git grep '\<xfstests'|wc -l 36 $ git grep '\<fstests'|wc -l 1 And I'm not turning up any references to fstests from google except for references to the mailing list name.

I've got my own handpicked list of tests, partly because I didn't notice the existance of "quick", partly because there were some failures I didn't have the time to triage. > (run tests in 'auto' group), which will take longer time but runs many > more tests. > > I test every RC release with local-mounted NFS, with NFSv3, > NFSv4.0/4.1/4.2.

I'll try to set aside some time to reconcile this with my own list and see if I can figure out some of the failures. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I don't see any evidence of that. The only thing that seems to be called fstests is the mailing list. I was very much against that name back then, but DAve won the fight. I don't think it's been very helpful evern retrospectively. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Test nfs4_getfacl gets ACL list correctly from server when the ACL length is close enough to the end of a page. On buggy NFS client getxattr could return ERANGE. Upstream commit ed92d8c137b7 ("NFSv4: fix getacl ERANGE for some ACL buffer sizes") fixed this bug in 4.11 kernel. Note that this reproducer was originally written by J. Bruce Fields. Cc: J. Bruce Fields <bfields@redhat.com> Cc: Weston Andros Adamson <dros@primarydata.com> Cc: linux-nfs@vger.kernel.org Signed-off-by: Eryu Guan <eguan@redhat.com> --- Hi all, This is the first attempt to add NFS specific tests to fstests with the hope that we'll have more NFS tests go to fstests and more people testing NFS by running fstests, it would be great if fstests could be part of the Linux NFS development workflow too. fstests does find NFS bugs (some are regression bugs), I noticed at least three regressions introduced in 4.12-rc1 release, one was reported to nfs list[1]. The other two regressions are: a) generic/095 crashes NFS (not sure server or client yet, not reproduced manually yet) b) copy_file_range(2) hang on NFSv4.2 mount, caught by just added copy_file_range tests. I'm still working on bisecting them now, will report to NFS list once I get something.
