[PATCHSET 1/8] fstests: fuzz non-root dquots on xfs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

During testing of online fsck part 2, I noticed that the dquot iteration
code in online fsck had some math bugs that resulted in it only ever
checking the root dquot.  Loooking into why I never noticed that, I
discovered that fstests also never checked them.  Strengthen our testing
by adding that.

While we're at it, hide a few more inode fields from the fuzzer, since
their contents are completely user-controlled and have no other
validation.  Hence they just generate noise in the test system and
increase runtimes unnecessarily.

If you're going to start using this code, I strongly recommend pulling
from my git trees, which are linked below.

This has been running on the djcloud for months with no problems.  Enjoy!
Comments and questions are, as always, welcome.
