Subject: [PATCH 00/10] xfs: fix various checking problems
Date: Sun, 03 Jun 2018 16:22:22 -0700 [thread overview]
Message-ID: <152806814253.18187.4009340462930782844.stgit@magnolia> (raw)
Hi all,
Here's a somewhat longer series of patches to fix some bugs and other
inadequacies in the metadata integrity checking of XFS. The first patch
makes it so that we can set the dax file flag on a directory so that the
daxiness propagates to new files even if the data device itself does not
support dax.
The rest of the series replaces various ASSERTs in the btree and
directory handling code with error logging and EFSCORRUPTED returns so
that maliciously corrupted filesystem images error out immediately (now
that ASSERT is no longer always fatal). All of these fixes were found
via online scrub fuzz tests.
Comments and questions are, as always, welcome.
