092ac26ea2 Fix undefined behavior with pointer addition in channeltls.c
In C, it's a bad idea to do this:

   char *cp = array;
   char *end = array + array_len;

   /* .... */

   if (cp + 3 >= end) { /* out of bounds */ }

because cp+3 might be more than one off the end of the array, and
you are only allowed to construct pointers to the array elements,
and to an element one past the end.  Instead you have to say

   if (cp - array + 3 >= array_len) { /* ... */ }

or something like that.

This patch fixes two of these: one in process_versions_cell
introduced in 0.2.0.10-alpha, and one in process_certs_cell
introduced in 0.2.3.6-alpha.  These are both tracked under bug
10363. "bobnomnom" found and reported both. See also 10313.

In our code, this is likely to be a problem as we used it only if we
get a nasty allocator that makes allocations end close to (void*)-1.
But it's best not to have to worry about such things at all, so
let's just fix all of these we can find.

6d0991ea08 Give no answer, not NOTIMPL, for unsupported DNS query types
According to reports, most programs degrade somewhat gracefully on
getting no answer for an MX or a CERT for www.example.com, but many
flip out completely on a NOTIMPL error.

Also, treat a QTYPE_ALL query as just asking for an A record.

The real fix here is to implement proposal 219 or something like it.

Fixes bug 10268; bugfix on 0.2.0.1-alpha.

Based on a patch from "epoch".

09dbcf3b82 Fix to 9841 fix: setting a token to NULL should clear it
Found by testing with chutney.  The old behavior was "fail an
assertion", which obviously isn't optimal.

c230ff4ca9 Look at all of a RESOLVED cell; not just the first answer.
Also, stop accepting the old kind of RESOLVED cells with no TTL
fields; they haven't been sent since 0.1.1.6-alpha.

This patch won't work without the fix to #10468 -- it will break
DNSPorts unless they set the proper ipv4/6 flags on entry_connection_t.

a68e6ea9c0 Fix documentation of torrc search order
We are searching @CONFDIR@ before $HOME, but the documentation
implied otherwise.

I screwed this up in f5e86bcd6c, when I
first documented the $HOME/.torrc possibility.

Fix for bug 9213; bugfix on 0.2.3.18-rc.
