It turns out that if there is no AAAA record the dns server (bind and MS
windows at least) do not return the A record when just asked for AAAA.

The two error tables need to be combined, but for now seperate the names.
(As the common parts of the tree now use the _common function,
errmap_unix.c must be included in the s3 autoconf build).

The iface_count, iface_n_bcast, and load_interfaces functions
conflicted with functions of the same name in source3, so the source4
functions were renamed. Hopefully we can actually wrap one around the
other in future.

This was just a wrapper around resolve_name_ex(), so just call that
instead.

This is consistent with the test names used by selftest, should
make the names less confusing and easier to integrate with other tools.

add a '.' if the name contains a '.' already, but not at the end

this better emulates what happens with real DNS

this converts all callers that use the Samba4 loadparm lp_ calling
convention to use the lpcfg_ prefix.

These were causing thousands of warnings on solaris8

This uses the new common code to read a file containing DNS host
names, so we don't have to use real DNS lookups in our test
environment.

By going via these tevent functions, we avoid needing to dereference
the struct socket_address, which may contain a 'struct sockaddr' or
strings. The new dns_host_file resolver returns in the form of a
struct sockaddr.

I'm hoping this will fix an occasional segfault I've noticed where
epoll still calls events on a closed fde

I think this completes commit 50feca550eed7828198b7c0fc5f0e5ddc863313d.
Now result should be handled correctly both for systems that
support EAI_NODATA but returns EAI_NONAME (as my Ubuntu 9.x)
and systems that doesn't support EAI_NODATA at all.

We were creating the name resolution context as a child of lp_ctx,
which meant when we gave up on a connection the timer on name
resolution kept running, and when it timed out the callback crashed as
the socket was already removed.
|
|
When tracking down complex connection problems its useful knowing what
name lookups failed.

A number of heimdal functions and constants have changed since we last

FreeBSD has explicitly deprecated EAI_NODATA as a return value from
getaddrinfo by removing it from netdb.h. On systems that don't have
EAI_NODATA, EAI_NONAME should be used instead.

E.g. this helps for DNS CNAME and SRV results.

That means we now return all ip addresses instead of just the first one.

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.

We should only include events.h where we really need it

This broke ldbedit against a LDAP server,
as the editor is called by "system()" which relies
on getting something useful out of waitpid().
TODO: we should create a generic infrastructure to
handle temporary forks and integrate the signal
handling with signal events there.
