dann frazier 226291aa46 ocfs2_connection_find() returns pointer to bad structure ... If ocfs2_live_connection_list is empty, ocfs2_connection_find() will return a pointer to the LIST_HEAD, cast as a ocfs2_live_connection. This can cause an oops when ocfs2_control_send_down() dereferences c->oc_conn: Call Trace: [<ffffffffa00c2a3c>] ocfs2_control_message+0x28c/0x2b0 [ocfs2_stack_user] [<ffffffffa00c2a95>] ocfs2_control_write+0x35/0xb0 [ocfs2_stack_user] [<ffffffff81143a88>] vfs_write+0xb8/0x1a0 [<ffffffff8155cc13>] ? do_page_fault+0x153/0x3b0 [<ffffffff811442f1>] sys_write+0x51/0x80 [<ffffffff810121b2>] system_call_fastpath+0x16/0x1b Fix by explicitly returning NULL if no match is found.
