Today I encountered the following problem on v3.8: [ 28.940032] general protection fault: 0000 [#1] PREEMPT SMP ... [ 28.984953] Call Trace: [ 28.986628 [] ocfs2_fast_symlink_readpage+0x70/0x1b0 [ocfs2] [ 28.988302] [] ? add_to_page_cache_lru+0x29/0x40 [ 28.989942] [] do_read_cache_page+0x7a/0x170 [ 28.991573] [] read_cache_page_async+0x14/0x20 [ 28.993212] [] read_cache_page+0x9/0x20 [ 28.994827] [] page_getlink.isra.9+0x25/0x80 [ 28.996442] [] page_follow_link_light+0x21/0x40 [ 28.998049] [] generic_readlink+0x3d/0xa0 [ 28.999653] [] sys_readlinkat+0xfb/0x130 [ 29.001246] [] sys_readlink+0x16/0x20 [ 29.002839] [] system_call_fastpath+0x1a/0x1f To my utter astonishment I found out that the issue is known since August 2012. And there is also a trivial fix for it.[0] The said fix found it's way into Oracle Unbreakable Linux very quickly, but not into mainline.[1] Now I'm wondering how much Oracle really cares about OCFS2 in mainline? Maybe there are some more unfixed vulnerabilities? Not amused, //richard [0] http://www.mail-archive.com/ocfs2-devel@oss.oracle.com/msg07774.html [1] https://oss.oracle.com/pipermail/el-errata/2012-October/003103.html
