* Fix bug 9082: avoid leak when freeing destroy cell queuesNick Mathewson2013-06-17
| | | | | | | | In my #7912 fix, there wasn't any code to remove entries from the (channel, circuit ID)->circuit map corresponding to queued but un-sent DESTROYs. Spotted by skruffy. Fixes bug 9082; bug not in any released Tor.
* Fix compile warnings wrt printf formating of int64_tNick Mathewson2013-06-13

* Add a changes file for bug 7912Nick Mathewson2013-06-13
| | | | | I'm calling it a bugfix on 0.2.0.1-alpha, since that's where cell queues were first introduced.
* Add destroy balance tracking and logging to circuitmuxAndrea Shepard2013-06-13

* Implementation of a fix for bug 7912Nick Mathewson2013-06-13
| | | | | | | | | I added the code to pass a destroy cell to a queueing function rather than writing it immediately, and the code to remember that we shouldn't reuse the circuit id until the destroy is actually sent, and the code to release the circuit id once the destroy has been sent... and then I finished by hooking destroy_cell_queue into the rest of Tor.
* Code to track on a circuit whether it has a "pending" delete cellNick Mathewson2013-06-13
| | | | This will be used in a fix for bug7912.
* Implement a placeholder mechanism in the channel,id->circ mapNick Mathewson2013-03-21
| | | | | We'll use this to help fix bug 7912, by providing a way to mark that a circuit ID can't get reused while a DESTROY is queued but not sent.

| | | | | | | | | | | | | | | | | | | | | | | | Inspired by #8042. As far as I know, OpenVMS is the only place you're likely to hit an unsigned time_t these days, and Tor's VMS support is... lacking. Still worth letting people know about it, though.

This patch introduces a new function that yields an error message on failure, so we can at least tell the user what to look for in their nonfunctional torrc. (Actually, it's the same function as before with a new name: parse_config_line_from_str is now a wrapper macro that the unit tests use.) Fixes bug 7950; fix on 0.2.0.16-alpha (58de695f9062576f) which first introduced the possibility of a torrc value not parsing correctly.

This pattern sucks for a few reasons: * It is nonobvious. * It is error-prone: decrementing 0 can be a bad choice indeed. * It really wants to have a function. It can also introduce bugs if the system time jumps backwards, or if MaxCircuitDirtiness is increased. So in this patch, I add an unusable_for_new_conns flag to origin_circuit_t, make it get checked everywhere it should (I looked for things that tested timestamp_dirty), and add a new function to frob it. For now, the new function does still frob timestamp_dirty (after checking for underflow and whatnot), in case I missed any cases that should be checking unusable_for_new_conns. Fixes bug 6174. We first used this pattern in 516ef41ac1fd26f338c, which I think was in 0.0.2pre26 (but it could have been 0.0.2pre27).

This isn't a live bug, since the call to is_or_protocol_version_known in channel_tls_process_versions_cell will reject any version number not in the range 1..4. Still, let's fix this before we accidentally start supporting version 256. Reported pseudonymously. Fixes bug 8062; bugfix on 0.2.0.10-alpha -- specifically, on commit 6fcda529, where during development I increased the width of a version to 16 bits without changing the type of link_proto.
