Comment 3 Wade Mealing 2006-07-25 02:08:40 UTC

This is not a duplicate of this bug, note that the avc messages are different,
the error messages are different, and the follow on bug that , the bug that it
is pointed to ( https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=188401 )
says it is fixed in rawhide.

I am running versions that are greater than the versions mentioned in that bug,
and the problem still persists.

Comment 4 Adam Jackson 2006-07-26 17:45:31 UTC

Fixed in 6.5-19 or better.

The problem was with how TLS dispatch was implemented.  It used a writable text
section to reduce the textrel cost, but selinux doesn't allow that.  Switching
back to non-TLS dispatch fixes it for now.
