The patch for 3228 made us try to run init_keys() before we had loaded
our state file, resulting in an assert inside init_keys. We had moved
it too early in the function.
Now it's later in the function, but still above the accounting calls.
Previously we did this nearer to the end (in the old_options &&
transition_affects_workers() block). But other stuff cares about
keys being consistent with options... particularly anything which
tries to access a key, which can die in assert_identity_keys_ok().
Fixes bug 3228; bugfix on 0.2.2.18-alpha.

When we added support for separate client tls certs on bridges in
a2bb0bfdd5 we forgot to correctly initialize this when changing
from relay to bridge or vice versa while Tor is running. Fix that
by always initializing keys when the state changes.
Fixes bug 2433.

We use a hash of the identity key to seed a prng to tell when an
accounting period should end. But thanks to the bug998 changes,
clients no longer have server-identity keys to use as a long-term seed
in accounting calculations. In any case, their identity keys (as used
in TLS) were never never fixed. So we can just set the wakeup time
from a random seed instead there. Still open is whether everybody
should be random.
This patch fixes bug 2235, which was introduced in 0.2.2.18-alpha.
Diagnosed with help from boboper on irc.
In a2bb0bf we started using a separate client identity key. When we are
in "public server mode" (that means not a bridge) we will use the same
key. Reusing the key without doing the proper refcounting leads to a
segfault on cleanup during shutdown. Fix that.
Also introduce an assert that triggers if our refcount falls below 0.
That should never happen.
We now require that:
- Only actual servers should ever call get_server_identity_key
- If you're being a client or bridge, the client and server keys should
differ.
- If you're being a public relay, the client and server keys
should be the same.
* Make tor_tls_context_new internal to tortls.c, and return the new
tor_tls_context_t from it.
* Add a public tor_tls_context_init wrapper function to replace it.

From the code:
zlib 1.2.4 and 1.2.5 do some "clever" things with macros. Instead of
saying "(defined(FOO) ? FOO : 0)" they like to say "FOO-0", on the theory
that nobody will care if the compile outputs a no-such-identifier warning.
Sorry, but we like -Werror over here, so I guess we need to define these.
I hope that zlib 1.2.6 doesn't break these too.
Possible fix for bug 1526.
Using strncpy meant that if listenaddress were ever >=
sizeof(sockaddr_un.sun_path), we would fail to nul-terminate
sun_path. This isn't a big deal: we never read sun_path, and the
kernel is smart enough to reject the sockaddr_un if it isn't
nul-terminated. Nonetheless, it's a dumb failure mode. Instead, we
should reject addresses that don't fit in sockaddr_un.sun_path.
Coverity found this; it's CID 428. Bugfix on 0.2.0.3-alpha.
When we rejected a descriptor for not being the one we wanted, we
were letting the parsed descriptor go out of scope.
Found by Coverity; CID # 30.
Bugfix on 0.2.1.26.
(No changes file yet, since this is not in any 0.2.1.x release.)
I'm not one to insist on C's miserly stack limits, but allocating a
256K array on the stack is too much even for me.
Bugfix on 0.2.1.7-alpha. Found by coverity. Fixes CID # 450.
We had all the code in place to handle this right... except that we
were unconditionally opening a PF_INET socket instead of looking at
sa_family. Ow.
Fixes bug 2574; not a bugfix on any particular version, since this
never worked before.
Rename crypto_pk_check_key_public_exponent to crypto_pk_public_exponent_ok:
it's nice to name predicates s.t. you can tell how to interpret true
and false.
The new behavior is to try to rename the old file if there is one there
that we can't read. In all likelihood, that will fail too, but at least
we tried, and at least it won't crash.
Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.
If the user sent a SIGNAL NEWNYM command after we fetched a rendezvous
descriptor, while we were building the introduction-point circuit, we
would give up entirely on trying to connect to the hidden service.
Original patch by rransom slightly edited to go into 0.2.1
