commit e09463f220ca9a1a1ecfda84fcda658f99a1f12a upstream. Do not set the b_modified flag in block's journal head should not until after we're sure that jbd2_journal_dirty_metadat() will not abort with an error due to there not being enough space reserved in the jbd2 handle. Otherwise, future attempts to modify the buffer may lead a large number of spurious errors and warnings. This addresses CVE-2018-10883. https://bugzilla.kernel.org/show_bug.cgi?id=200071 Change-Id: Id8501e9b600fb35003f6cb9951cc187c1ad5801f Signed-off-by: Theodore Ts'o <tytso@mit.edu> [bwh: Backported to 3.16: Drop the added logging statement, as it's on a code path that doesn't exist here] Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Kevin F.
