Description

Currently, the most DNS records are not validated in ipa-server on RHEL. I have, however, already submitted a patch implementing all these validators (including kx): http://www.redhat.com/archives/freeipa-devel/2011-September/msg00042.html It is targeted for FreeIPA 3.0. If this BZ gets 6.2 ACKs I can backport the patch for RHEL 6.2. Relevant upstream ticket: https://fedorahosted.org/freeipa/ticket/1106 Fixed upstream: master: efc3e2c1f7a3dcf5e94736395d39e1fa2800a490 This bug still appears present in : ipa-server-2.1.3-9.el6.x86_64 bind-dyndb-ldap-0.2.0-7.el6.x86_64 Maybe I do not have a new enough version of these tools? Also, regarding comment #3, the referenced upstream ticket doesn't seem to relate to this problem. That upstream ticket relates to the behaviour that adding bad records of some types breaks resolution all together. The behaviour in this bug is that when you add a bad kx record, name resolution continues working, but invalid values come out of bind when asked about a kx record. Improved DNS validation was pushed to master branch only, i.e. this is targeted for upcoming upstream release FreeIPA 3.0 planned for RHEL 6.3. I think comment #3 is correct. The Trac ticket 1106 added improved validation for almost all DNS records, including KX. There will be more major improvements in this area in ticket 2082: https://fedorahosted.org/freeipa/ticket/2082 Broken DNS resolution when a invalid DNS data are saved to a zone are dealt with in Bug 750947 (ticket 2072). :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: [ LOG ] :: ipa-dns-158: Bug 738788 - ipa dnsrecord-add allows invalid kx records :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: :: [08:29:33] :: verifies https://bugzilla.redhat.com/show_bug.cgi?id=738788 ipa: ERROR: invalid 'preference': must be at least 0 :: [ PASS ] :: Running 'ipa dnsrecord-add newzone @ --kx-rec "-1 1.2.3.4" | grep "ipa: ERROR: invalid 'preference': must be at least 0"' ipa: ERROR: invalid 'preference': can be at most 65535 :: [ PASS ] :: Running 'ipa dnsrecord-add newzone @ --kx-rec "333383838383 1.2.3.4" | grep "ipa: ERROR: invalid 'preference': can be at most 65535"' 'fb3c69d4-aff0-43c2-96d5-32beffff0c6d' ipa-dns-158 result: PASS Verified: ipa-server-2.2.0-3.el6.x86_64
