Subject: [RFC 00/12] xfs: more and better verifiers
Date: Thu, 17 Aug 2017 16:31:29 -0700	[thread overview]
Message-ID: <150301268960.5851.2513223883233763065.stgit@magnolia> (raw)

Hi all,

This RFC combines all the random little fixes and improvements to the
verifiers that we've been talking about for the past month or so into a
single patch series!

We start by refactoring the long format btree block header verifier into
a single helper functionn and de-macroing dir block verifiers to make
them less shouty.  Next, we change verifier functions to return the
approximate instruction pointer of the faulting test so that we can
report more precise fault information to dmesg/tracepoints.  Then, we
move on to creating verifiers for all the inline format fork formats,
and create a helper function for _iget that can dispatch inline
verification.  The ability to supply custom verifier functions will be
used by xfs_repair to deal with corrupt inodes.  The last patch enables
us to (re)check the structure of incore metadata buffers to try to
detect memory corruption.
