2013-03-09s4-dns: dlz_bind9: Check result to avoid segfaultStefan Gohmann1-1/+1
We saw this issue in a customer environment with many CNF objects. I wasn't able to reproduce it, but I got the following core dump: (gdb) directory samba4-4.0.0~rc6/source4/dns_server/ Source directories searched: /root/samba4-4.0.0~rc6/source4/dns_server:$cdir:$cwd (gdb) bt #0 0xb4b0bc13 in dlz_lookup_types (state=0x9648e48, zone=0xb659b9a8 "xxxxxx.xxxxx.de", name=0xb659bda8 "client9173", lookup=0xb6db7588, types=0x0) at ../source4/dns_server/dlz_bind9.c:830 #1 0xb4b0bdb8 in dlz_lookup (zone=0xb659b9a8 "xxxxxx.xxxxx.de", name=0xb659bda8 "client9173", dbdata=0x9648e48, lookup=0xb6db7588) at ../source4/dns_server/dlz_bind9.c:875 #2 0x080b43d8 in dlopen_dlz_lookup () #3 0xb7701755 in findnode () from /usr/lib/libdns.so.81 #4 0xb7701d22 in find () from /usr/lib/libdns.so.81 #5 0xb7639e5f in dns_db_find () from /usr/lib/libdns.so.81 #6 0x08075476 in query_find () #7 0x0807acb9 in ns_query_start () #8 0x08060712 in client_request () #9 0xb743022b in run () from /usr/lib/libisc.so.81 #10 0xb7216955 in start_thread () from /lib/i686/cmov/libpthread.so.0 #11 0xb706c1de in clone () from /lib/i686/cmov/libc.so.6 (gdb) f 0 #0 0xb4b0bc13 in dlz_lookup_types (state=0x9648e48, zone=0xb659b9a8 "xxxxxx.xxxxx.de", name=0xb659bda8 "client9173", lookup=0xb6db7588, types=0x0) at ../source4/dns_server/dlz_bind9.c:830 830 el = ldb_msg_find_element(res->msgs[0], "dnsRecord"); (gdb) p res->msgs $1 = (struct ldb_message **) 0x0 (gdb) p res->count $2 = 0 (gdb) Reviewed-by: Andrew Bartlett <abartlet@samba.org>

2012-10-07s4-dns: Ignore zones that shouldn't be returned currentlyMatthieu Patou1-1/+7
RootDNSServers should never be returned (Windows DNS server don't) ..TrustAnchors should never be returned as is, (Windows returns TrustAnchors) and for the moment we don't support DNSSEC so we'd better not return this zone.

2012-06-15lib/param: Create a seperate server role for "active directory domain ↵Andrew Bartlett1-1/+1
controller" This will allow us to detect from the smb.conf if this is a Samba4 AD DC which will allow smarter handling of (for example) accidentially starting smbd rather than samba. To cope with upgrades from existing Samba4 installs, 'domain controller' is a synonym of 'active directory domain controller' and new parameters 'classic primary domain controller' and 'classic backup domain controller' are added.

2012-06-06s4 dns: Correctly handle A questions for CNAMEsKai Blin1-5/+56
When an A/AAAA lookup is made for a name that actually is a CNAME record, we need to return the CNAME record, and then do the A/AAAA lookup for the name the CNAME points at. This still fails for CNAMEs pointing at records for domains we need to ask our forwarders for. Autobuild-User: Kai Blin <kai@samba.org> Autobuild-Date: Wed Jun 6 15:23:55 CEST 2012 on sn-devel-104
