2013-02-17Fallback to the internal resolver on EAI_FAIL.Landon Fuller1-1/+3
On Linux, non-RFC 1034-complaint names (such as gc._msdsc.example.org) will result in the resolver returning the non-POSIX EAI_NODATA. In that case, the case statement here would fall back on the internal resolver, allowing resolution to complete successfully. On FreeBSD, the libc resolver uses the same validation code, but the POSIX result of EAI_FAIL is returned instead of EAI_NODATA. Since there was no case for this error code, no fallback to the internal resolver would occur. This led to replication failing on FreeBSD.

2012-05-23dns: fix comments and make s4/libcli/resolve dns resolver workingAlexander Bokovoy1-1/+1
After migrating to use libaddns, reply_to_addrs() needed to change the way answers are iterated through. Originally libroken implementation gave all answers as separate records with last one being explicitly NULL. libaddns unmarshalling code gives all non-NULL answers and should be iterated with explicit reply->num_answers in use.

Without this, netbios name lookups do not work, as we never fall back to them. This caused segfaults from e38d97e0424f7e5b21c8b7ac0b1f1bac33f19d69 to 251209bd6f6e66ca9bcf28cd652d85d1cd729fdc and then name lookup failure or timeouts until this patch.

2008-12-17s4:libcli/resolve: add getaddrinfo()/dns_looup() resolvingStefan Metzmacher1-0/+484
This "dns_ex" module provides flexible lookup methods for dns lookups. The getaddrinfo() part looks at /etc/hosts and dns. As it handles CNAME replies badly we fallback to use dns_lookup(name, "A"). The dns_lookup() makes DNS SRV lookups possible. This module is not a real resolve module, it's just a generic helper as the nbtlist.c code is. The next step will be that the "host" module will use the dns_ex.c code. metze
