7dbf66713f When freeing a cert_list_t, avoid memory leak.
We were freeing these on exit, but when we added the dl_status_map
field to them in fddb814f, we forgot to arrange for it to be freed.

I've moved the cert_list_free() code into its own function, and added
an appropriate dsmap_free() call.

Fixes bug 9644; bugfix on 0.2.4.13-alpha.

dece40fd77 Fix an assert when disabling ORPort with accounting disabled.
The problem was that the server_identity_key_is_set() function could
return true under conditions where we don't really have an identity
key -- specifically, where we used to have one, but we stopped being a
server.

This is a fix for 6979; bugfix on 0.2.2.18-alpha where we added that
assertion to get_server_identity_key().

a2754d418d Try using INT_MAX, not SOMAXCONN, to set listen() backlog.
Fall back to SOMAXCONN if INT_MAX doesn't work.

We'd like to do this because the actual maximum is overrideable by the
kernel, and the value in the header file might not be right at all.
All implementations I can find out about claim that this is supported.

Fix for 9716; bugfix on every Tor.

2c877d2da4 collect and log statistics about onionskins received/processed
we skip onionskins that came from non-relays, so we're less likely to
run into privacy troubles.

f51add6dbc Revert e443beff and solve it a different way
Now we explicitly check for overflow.

This approach seemed smarter than a cascade of "change int to unsigned
int and hope nothing breaks right before the release".

Nick, feel free to fix in a better way, maybe in master.

it can still overflow, but the damage is very small now.

4f3dbb3c0a use !cbt_disabled in place of LearnCBT to avoid needless circs
This would make us do testing circuits "even when cbt is disabled by
consensus, or when we're a directory authority, or when we've failed
to write cbt history to our state file lately." (Roger's words.)

This is a fix for 9671 and an improvement in our fix for 5049.
The original misbehavior was in 0.2.2.14-alpha; the incomplete
fix was in 0.2.3.17-beta.

0daa26a473 Send NETINFO on receiving a NETINFO if we have not yet sent one.
(Backport to Tor 0.2.3)

Relays previously, when initiating a connection, would only send a
NETINFO after sending an AUTHENTICATE.  But bridges, when receiving a
connection, would never send AUTH_CHALLENGE.  So relays wouldn't
AUTHENTICATE, and wouldn't NETINFO, and then bridges would be
surprised to be receiving CREATE cells on a non-open circuit.

Fixes bug 9546.

d5cfbf96a2 Fix an uninitialized-read when parsing v3 introduction requests.
Fortunately, later checks mean that uninitialized data can't get sent
to the network by this bug.  Unfortunately, reading uninitialized heap
*can* (in some cases, with some allocators) cause a crash if you get
unlucky and go off the end of a page.
