Subject: [PATCH 4.19 36/97] jbd2: fix ocfs2 corrupt when clearing block group bits
Date: Thu, 27 Feb 2020 14:36:44 +0100	[thread overview]
Message-ID: <20200227132220.464633325@linuxfoundation.org> (raw)
In-Reply-To: <20200227132214.553656188@linuxfoundation.org>

From: wangyan <wangyan122@huawei.com>

commit 8eedabfd66b68a4623beec0789eac54b8c9d0fb6 upstream.

I found a NULL pointer dereference in ocfs2_block_group_clear_bits().
The running environment:
	kernel version: 4.19
	A cluster with two nodes, 5 luns mounted on two nodes, and do some
	file operations like dd/fallocate/truncate/rm on every lun with storage
	network disconnection.

The fallocate operation on dm-23-45 caused an null pointer dereference.

The information of NULL pointer dereference as follows:
	[577992.878282] JBD2: Error -5 detected when updating journal superblock for dm-23-45.
	[577992.878290] Aborting journal on device dm-23-45.

                                bh2jh(group_bh)->b_committed_data;

If handle->h_transaction == NULL, then jbd2_write_access_granted()
does not really guarantee that journal_head will stay around,
not even speaking of its b_committed_data. The bh2jh(group_bh)
can be removed after ocfs2_journal_access_gd() and before call
"bh2jh(group_bh)->b_committed_data". So, we should move
is_handle_aborted() check from do_get_write_access() into
jbd2_journal_get_undo_access() and jbd2_journal_get_write_access()
before the call to jbd2_write_access_granted().
