This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping In kernel/audit.c:audit_get_stamp() try to replace if (ctx) with if (ctx && ctx->in_syscall), see if that solves the problem. ought to be fixed by mainline commit 48887e63d6e057543067327da6b091297f7fe645 Author: Al Viro <viro.org.uk> Date: Sat Dec 6 01:05:50 2008 -0500 [PATCH] fix broken timestamps in AVC generated by kernel threads Timestamp in audit_context is valid only if ->in_syscall is set. Fixed in 2.6.28 but not in 2.6.27-stable. Will be fixed in the f10 2.6.29 update. This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
The kernel may produce audit records with zero timestamp: > <SNIP> type=AVC msg=audit(0.000:6760): <SNIP> comm="lockd" > <SNIP> type=AVC msg=audit(0.000:381): <SNIP> comm="nfsd4" The records are created by kernel threads; when a kernel thread is created, an audit context is created and zeroed. The timestamp is set on system call entry in ordinary threads, but there is no system call entry in kernel threads, so the original zero timestamp is used in all audit records related to kernel threads.
