In FC5, the security contexts have been extended with an additional field for the Multi-Category Security (MCS) and Multi-Level Security (MLS) support, see http://www.livejournal.com/users/james_morris/5583.html and http://www.livejournal.com/users/james_morris/5020.html Older SELinux kernels with MLS support disabled (i.e. RHEL4/CentOS4, FC3, older FC4 kernels) will reject the extended security contexts as being invalid, which yields the error you are seeing. Some compatibility patches were upstreamed to help with this problem, and I think that they went into the latest FC4 kernel update, but I'm not sure about RHEL4 yet. On the RH9 side, you are likely running into the old xattr-on-symlinks problem in older 2.4 kernels; the fix for that problem was backported to a FC1 kernel update long ago, IIRC, but naturally not to RH9. -- Stephen Smalley National Security Agency -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
