Comment 2 Daniel Walsh 2007-08-20 15:51:28 EDT
For some reason /dev/random is labeled incorrectly.
Probably in the chroot environment.

restorecon -R -v /var/named
Comment 3 Milan Zázrivec 2007-08-21 04:10:51 EDT
restorecon -R -v /var/named helps, but since this was a new
install, relabeling just to make this denial disappear is
not acceptable.

Reopening and reassigning to bind.

Comment 4 Adam Tkac 2007-08-21 09:34:36 EDT
problem is that /dev/random is mislabeled during installation so
/usr/bin/chcon --reference=/dev/random ${BIND_CHROOT_PREFIX}/dev/random;
makes ${BIND_CHROOT_PREFIX}/dev/random mislabeled

proposed patch

use restorecon instead chcon
Comment 6 Adam Tkac 2007-08-21 09:40:56 EDT
Adding to 5.2 proposed

For QA:

try install bind-chroot in default installation (with enabled selinux). Old
package has mislabeled /dev/random in chroot
