I had a half-built mechanism to track, during the voting process,
whether the Ed25519 value (or lack thereof) reflected a true
consensus among the authorities. But we never actually inserted this
field in the consensus.
The key idea here is that we first attempt to match up votes by pairs
of <Ed,RSA>, where <Ed> can be NULL if we're told that there is no
Ed key. If this succeeds, then we can treat all those votes as 'a
consensus for Ed'. And we can include all other votes with a
matching RSA key and no statement about Ed keys as being "also about
the same relay."
After that, we look for RSA keys we haven't actually found an entry
for yet, and see if there are enough votes for them, NOT considering
Ed keys. If there are, we match them as before, but we treat them
as "not a consensus about ed".
When we include an entry in a consensus, if it does not reflect a
consensus about ed keys, then we include a new NoEdConsensus flag on
it.
This is all only for consensus method 22 or later.
Also see corresponding dir-spec patch.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.
This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us. It is part of bug 18318, and the root cause of 17668.
If we're a server with no address configured, resolve_my_hostname
will need this. But not otherwise. And the preseeding itself can
consume a few seconds if like tails we have no resolvers.
Fixes bug 18548.
Launching 7 descriptor fetches makes a connection to each HSDir that is 6
and the seventh one fails to pick an HSDir because they are all being used
already so it was killing all pending connections at once.

This simplifies relay behavior, because the relay offers the hsdir
functionality independent of whether the directory authorities have
decided this relay is suitable for clients to use yet.
Implements ticket 18332.
This is in accordance with our usual policy against freelists,
now that working allocators are everywhere.
It should also make memarea.c's coverage higher.
I also doubt that this code ever helped performance.
Short version: clang asan hates the glibc strcmp macro in
bits/string2.h if you are passing it a constant string argument of
length two or less. (I could be off by one here, but that's the
basic idea.)
Closes issue 14821.
CentOS 6 is roughly the oldest thing we care about developers still
using, and it has autoconf 2.63 / automake 1.11. These are both
older than openssl 1.0.0, so anybody who can't upgrade past those
probably can't upgrade to a modern openssl either. And since only
people building from git or editing configure.ac/Makefile.am need to
use autotools, I'm not totally enthused about keeping support for
old ones anyway.
Closes ticket 17732.
Previously, I had left in some debugging code with /*XXX*/ after it,
which nobody noticed. Live and learn! Next time I will use /*XXX
DO NOT COMMIT*/ or something.
We need to define a new consensus method for this; consensus method
21 shouldn't actually be used.
Fixes bug 17702; bugfix on 0.2.7.2-alpha.
Now, when a user who has set EntryNodes finishes bootstrapping, Tor
automatically repopulates the guard set based on this new directory
information. Fixes bug 16825; bugfix on 0.2.3.1-alpha.
If unix socket was configured as listener (such as a ControlSocket or a
SocksPort unix socket), and tor was started as root but not configured
to switch to another user, tor would segfault while trying to string
compare a NULL value. Fixes bug 18261; bugfix on 0.2.8.1-alpha. Patch
by weasel.
We use sensible parameters taken from common sources, and no longer
have dynamic DH groups as an option, but it feels prudent to have
OpenSSL validate p and g at initialization time.
