Red Hat Bugzilla – Bug 160562
Race condition in __get_lease()
Last modified: 2013-08-05 21:15:13 EDT
This is the RHEL2.1-ia64 version of Bug 156636:
"Kernel has oopsed several times. Netdump has capture the oops but not a
complete vmcore. The oops below is representative. The changes documented in the
following link are not present in the RH kernel. I feel the race identified by
Stephen Rothwell involving the checking of whether inode->i_flock is not NULL
and the subseqeunt use of that pointer is a likely explanation for these oopses."
Although this problem has not been reported (to my knowledge) on RHEL2.1-ia64,
the code (and therefore the vulnerability) is exactly the same.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
