A fair number of our mock_impl declarations were messed up so that
even our special AM_ETAGSFLAGS couldn't find them.
This should be a whitespace-only patch.
So far, the TTLs for both A and AAAA records were not initialised,
resulting in exit relays sending back the value 60 to Tor clients. This
also impacts exit relays' DNS cache -- the expiry time for all domains
is set to 60.
This fixes <https://bugs.torproject.org/19025>.
The server-side clipping now clamps to one of two values, both
for what to report, and how long to cache.
Additionally, we move some defines to dns.h, and give them better
names.

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it. In a few cases, I've added TODO
notes about refactoring opportunities.
I've also renamed an argument, and fixed a few DOCDOC comments.
Only some very ancient distributions don't ship with Libevent 2 anymore,
even the oldest supported Ubuntu LTS version has it. This allows us to
get rid of a lot of compat code.
Also, avoid crashing when we attempt to double-remove an edge
connection from the DNS resolver: just log a bug warning instead.
Fixes bug 14129. Bugfix on 0d20fee2fb, which was in 0.0.7rc1.
jowr found the bug. cypherpunks wrote the fix. I added the log
message and removed the assert.
We're calling mallocfn() and reallocfn() in the HT_GENERATE macro
with the result of a product. But that makes any sane analyzer
worry about overflow.
This patch keeps HT_GENERATE having its old semantics, since we
aren't the only project using ht.h. Instead, define a HT_GENERATE2
that takes a reallocarrayfn.
I've made an exception for cases where I'm sure that users can't
influence the inputs. This is likely to cause a slowdown somewhere,
but it's safer to siphash everything and *then* look for cases to
optimize.
This patch doesn't actually get us any _benefit_ from siphash yet,
since we don't really randomize the key at any point.
This is meant to avoid conflict with the built-in log() function in
math.h. It resolves ticket 7599. First reported by dhill.

Previously, I was freaking out about passing an unspec address to
dns_found_answer() on an error, since I was using the address type to
determine whether the error was an error on an ipv4 address lookup or
on an ipv6 address lookup. But now dns_found_answer() has a separate
orig_query_type argument to tell what kind of query it is, so there's
no need to freak out.
* If there's an IPv4 and an IPv6 address, return both in the resolved
cell.
* Treat all resolve requests as permitting IPv6, since by the spec they're
allowed to, and by the code that won't break anything.
IPv4-only exits have an implicit "reject [::]/0", which was making
policy_is_reject_star() return 1 for them, making us refuse to do
hostname lookups.
This fix chanes policy_is_reject_star() to ask about which family we meant.
The code previously detected wildcarding and replaced wildcarded
answers with DNS_STATUS_FAILED_PERMANENT. But that status variable
was no longer used! Remove the status variable, and instead change
the value of 'result' in evdns_callback.
Thank goodness for compiler warnings. In this case,
unused-but-set-variable.
Thanks to Linus for finding this one.
