linux-toradex.git/fs/ocfs2, branch v3.4.8 Linux kernel for Apalis and Colibri modules ocfs2: fix NULL pointer dereference in __ocfs2_change_file_space() 2012-07-16T16:04:45+00:00 Luis Henriques luis.henriques@canonical.com 2012-07-11T21:02:10+00:00 bb2b649805527af1d823f871e7e3a95c4e6a018e commit a4e08d001f2e50bb8b3c4eebadcf08e5535f02ee upstream. As ocfs2_fallocate() will invoke __ocfs2_change_file_space() with a NULL as the first parameter (file), it may trigger a NULL pointer dereferrence due to a missing check.

ocfs2: clear unaligned io flag when dio fails 2012-07-16T16:04:24+00:00 Junxiao Bi junxiao.bi@oracle.com 2012-06-27T09:09:55+00:00 47e38c598d1a3bf7d01c540c46d2039708337622 commit 3e5d3c35a68c9a933bdbdd8685bd1a205b57e806 upstream. The unaligned io flag is set in the kiocb when an unaligned dio is issued, it should be cleared even when the dio fails, or it may affect the following io which are using the same kiocb.
