Description Jason Baron 2006-05-12 18:39:51 UTC 
Description of problem:

Some time ago, a bug was fixed upstream [1] where a rewrite of the
readv/writev code did not include adding appropriate LSM hooks, and these
syscalls are unmediated in RHEL4.

Additionally, Al Viro just discovered that the upstream fix neglected the
compat code.

This patch fixes both cases.  I've verified the problem and the fix.

Please apply.
