This update fixes the following security issue :
This update also fixes the following bugs :
Due to an off-by-one error, gfs2_grow failed to take the very last ‘rgrp’ parameter into account when adding up the new free space. With this update, the GFS2 kernel properly counts all the new resource groups and fixes the ‘statfs’ file correctly. (BZ#666792)
Prior to this update, a multi-threaded application, which invoked popen(3) internally, could cause a thread stall by FILE lock corruption. The application program waited for a FILE lock in glibc, but the lock seemed to be corrupted, which was caused by a race condition in the COW (Copy On Write) logic. With this update, the race condition was corrected and FILE lock corruption no longer occurs. (BZ#667050)
If an error occurred during I/O, the SCSI driver reset the ‘megaraid_sas’ controller to restore it to normal state. However, on Scientific Linux 5, the waiting time to allow a full reset completion for the ‘megaraid_sas’ controller was too short. The driver incorrectly recognized the controller as stalled, and, as a result, the system stalled as well. With this update, more time is given to the controller to properly restart, thus, the controller operates as expected after being reset.
(BZ#667141)
The system must be rebooted for this update to take effect.
