xfs: update the pag for the last AG at recovery time

xfs: update the pag for the last AG at recovery time

commit 4a201dcfa1ff0dcfe4348c40f3ad8bd68b97eb6c upstream.

Currently log recovery never updates the in-core perag values for the
last allocation group when they were grown by growfs. This leads to
btree record validation failures for the alloc, ialloc or finotbt
trees if a transaction references this new space.

Found by Brian's new growfs recovery stress test.

xfs: update the file system geometry after recoverying superblock buffers

commit 6a18765b54e2e52aebcdb84c3b4f4d1f7cb2c0ca upstream.

Primary superblock buffers that change the file system geometry after a
growfs operation can affect the operation of later CIL checkpoints that
make use of the newly added space and allocation groups.

Apply the changes to the in-memory structures as part of recovery pass 2,
to ensure recovery works fine for such cases.

In the future we should apply the logic to other updates such as features
bits as well.

The fuzzed image contains an AGF with an obviously garbage
agf_refcount_level value of 32, and a dirty log with a buffer log item
for that AGF. The ondisk AGF has a higher LSN than the recovered log
item. xlog_recover_buf_commit_pass2 reads the buffer, compares the
LSNs, and decides to skip replay because the ondisk buffer appears to be
newer.

Unfortunately, the ondisk buffer is corrupt, but recovery just read the
buffer with no buffer ops specified:

error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno,
buf_f->blf_len, buf_flags, &bp, NULL);

Skipping the buffer leaves its contents in memory unverified. This sets
us up for a kernel crash because xfs_refcount_recover_cow_leftovers
reads the buffer (which is still around in XBF_DONE state, so no read
verification) and creates a refcountbt cursor of height 32. This is
impossible so we run off the end of the cursor object and crash.

Fix this by invoking the verifier on all skipped buffers and aborting
log recovery if the ondisk buffer is corrupt. It might be smarter to
force replay the log item atop the buffer and then see if it'll pass the
write verifier (like ext4 does) but for now let's go with the
conservative option where we stop immediately.
