Subject: [PATCH 5.0 13/52] udf: Fix crash on IO error during truncate
Date: Tue, 26 Mar 2019 15:30:00 +0900 [thread overview]
Message-ID: <20190326042701.589643019@linuxfoundation.org> (raw)
In-Reply-To: <20190326042700.963224437@linuxfoundation.org>
5.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@suse.cz>
commit d3ca4651d05c0ff7259d087d8c949bcf3e14fb46 upstream.
When truncate(2) hits IO error when reading indirect extent block the
code just bugs with:
kernel BUG at linux-4.15.0/fs/udf/truncate.c:249!
...
Fix the problem by bailing out cleanly in case of IO error.
