ext4: add checks for errors from jbd2

If the journal has aborted due to a checkpointing failure, we
have to keep the contents of the journal space.  Otherwise, the
filesystem will lose uncheckpointed metadata completely and
become inconsistent.  To avoid this, we need to keep needs_recovery
flag if checkpoint has failed.

With this patch, ext4_put_super() detects a checkpointing failure
from the return value of journal_destroy(), then it invokes
ext4_abort() to make the filesystem read only and keep
needs_recovery flag.  Errors from jbd2_journal_flush() are also
handled by this patch in some places.

16 years agojbd2: fix error handling for checkpoint io
Hidehiro Kawai [Sat, 11 Oct 2008 00:29:13 +0000 (20:29 -0400)]
jbd2: fix error handling for checkpoint io

When a checkpointing IO fails, current JBD2 code doesn't check the
error and continue journaling.  This means latest metadata can be
lost from both the journal and filesystem.

This patch leaves the failed metadata blocks in the journal space
and aborts journaling in the case of jbd2_log_do_checkpoint().
To achieve this, we need to do:

1. don't remove the failed buffer from the checkpoint list where in
   the case of __try_to_free_cp_buf() because it may be released or
   overwritten by a later transaction
2. jbd2_log_do_checkpoint() is the last chance, remove the failed
   buffer from the checkpoint list and abort the journal
3. when checkpointing fails, don't update the journal super block to
   prevent the journaled contents from being cleaned.  For safety,
   don't update j_tail and j_tail_sequence either
4. when checkpointing fails, notify this error to the ext4 layer so
   that ext4 don't clear the needs_recovery flag, otherwise the
   journaled contents are ignored and cleaned in the recovery phase
5. if the recovery fails, keep the needs_recovery flag
6. prevent jbd2_cleanup_journal_tail() from being called between
   __jbd2_journal_drop_transaction() and jbd2_journal_abort()
   (a possible race issue between jbd2_log_do_checkpoint()s called by
   jbd2_journal_flush() and __jbd2_log_wait_for_space())

16 years agojbd2: abort when failed to log metadata buffers
Hidehiro Kawai [Sun, 12 Oct 2008 20:39:16 +0000 (16:39 -0400)]
jbd2: abort when failed to log metadata buffers

If we failed to write metadata buffers to the journal space and
succeeded to write the commit record, stale data can be written
back to the filesystem as metadata in the recovery phase.

To avoid this, when we failed to write out metadata buffers,
abort the journal before writing the commit record.

We can also avoid this kind of corruption by using the journal
checksum feature because it can detect invalid metadata blocks in the
journal and avoid them from being replayed.  So we don't need to care
about asynchronous commit record writeout with a checksum.
