Dan Carpenter b761fd2821 ocfs2: fix a use after free on error ... [ Upstream commit c57d117f2b2f2a19b570c36f2819ef8d8210af20 ] The error handling in this function frees "reg" but it is still on the "o2hb_all_regions" list so it will lead to a use after freew. Joseph Qi points out that we need to clear the bit in the "o2hb_region_bitmap" as well Link: https://lkml.kernel.org/r/YBk4M6HUG8jB/jc7@mwanda Fixes: 1cf257f511 ("ocfs2: fix memory leak") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Joseph Qi <joseph.qi@linux.alibaba.com> Cc: Mark Fasheh <mark@fasheh.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Junxiao Bi <junxiao.bi@oracle.com> Cc: Changwei Ge <gechangwei@live.cn> Cc: Gang He <ghe@suse.com> Cc: Jun Piao <piaojun@huawei.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2021-03-04 11:38:18 +01:00
