* Merge remote-tracking branch 'public/ticket6799_024_v2_squashed'Nick Mathewson2014-06-11
|\ | | | | | | | | | | | | | | | | | | Conflicts: src/or/channel.c src/or/circuitlist.c src/or/connection.c Conflicts involved removal of next_circ_id and addition of unusable-circid tracking.
| * Replace last_added_nonpadding with last_had_circuitsNick Mathewson2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | The point of the "idle timeout" for connections is to kill the connection a while after it has no more circuits. But using "last added a non-padding cell" as a proxy for that is wrong, since if the last circuit is closed from the other side of the connection, we will not have sent anything on that connection since well before the last circuit closed. This is part of fixing 6799. When applied to 0.2.5, it is also a fix for 12023.
| * Give each or_connection_t a slightly randomized idle_timeoutNick Mathewson2014-06-11
| | | | | | | | | | | | | | | | | | | | | | | | Instead of killing an or_connection_t that has had no circuits for the last 3 minutes, give every or_connection_t a randomized timeout, so that an observer can't so easily infer from the connection close time the time at which its last circuit closed. Also, increase the base timeout for canonical connections from 3 minutes to 15 minutes. Fix for ticket 6799.
* | Use tor_getpw{nam,uid} wrappers to fix bug 11946Nick Mathewson2014-05-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When running with User set, we frequently try to look up our information in the user database (e.g., /etc/passwd). The seccomp2 sandbox setup doesn't let us open /etc/passwd, and probably shouldn't. To fix this, we have a pair of wrappers for getpwnam and getpwuid. When a real call to getpwnam or getpwuid fails, they fall back to a cached value, if the uid/gid matches. (Granting access to /etc/passwd isn't possible with the way we handle opening files through the sandbox. It's not desirable either.)

| * | scan-build: get_proxy_addrport should always set its outputsNick Mathewson2014-04-18
| | | | | | | | | | | | | | | | | | | | | When get_proxy_addrport returned PROXY_NONE, it would leave addr/port unset. This is inconsistent, and could (if we used the function in a stupid way) lead to undefined behavior. Bugfix on 5b050a9b0, though I don't think it affects tor-as-it-is.

| * | Switch to random allocation on circuitIDs.Nick Mathewson2014-04-18
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a possible root cause of 11553 by only making 64 attempts at most to pick a circuitID. Previously, we would test every possible circuit ID until we found one or ran out. This algorithm succeeds probabilistically. As the comment says: This potentially causes us to give up early if our circuit ID space is nearly full. If we have N circuit IDs in use, then we will reject a new circuit with probability (N / max_range) ^ MAX_CIRCID_ATTEMPTS. This means that in practice, a few percent of our circuit ID capacity will go unused. The alternative here, though, is to do a linear search over the whole circuit ID space every time we extend a circuit, which is not so great either. This makes new vs old clients distinguishable, so we should try to batch it with other patches that do that, like 11438.

| | | | | | | | | | | | | | | | | | | | | I'm making this change now since ipfw will want its own option too, and proliferating options here isn't sensible. (See #10582 and #10267)
