| | | | | | | | | | | | | | | | | | | | | | Use a per-channel ratelim_t to control the rate at which we report failures for each channel. Explain why I picked N=32. Never return a zero circID. Thanks to Andrea and to cypherpunks.

| * 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.
* | Test code for implementation of faster circuit_unlink_all_from_channelNick Mathewson2014-03-14
| | | | | | | | | | | | | | | | This contains the obvious implementation using the circuitmux data structure. It also runs the old (slow) algorithm and compares the results of the two to make sure that they're the same. Needs review and testing.
* | Siphash-2-4 is now our hash in nearly all cases.Nick Mathewson2014-02-12
| | | | | | | | | | | | | | | | | | | | I've made an exception for cases where I'm sure that users can't influence the inputs. This is likely to cause a slowdown somewhere, but it's safer to siphash everything and *then* look for cases to optimize. This patch doesn't actually get us any _benefit_ from siphash yet, since we don't really randomize the key at any point.

| * Fix a bug in our bug 9776 fix.Nick Mathewson2013-10-02
| | | | | | | | | | | | | | | | | | By calling circuit_n_chan_done() unconditionally on close, we were closing pending connections that might not have been pending quite for the connection we were closing. Fix for bug 9880. Thanks to skruffy for finding this and explaining it patiently until we understood.

* | 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.

* | 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.
* Don't assert when writing a cell to a CLOSING connection.Nick Mathewson2013-03-19

* Fix 8447: use %u to format circid_t.Nick Mathewson2013-03-10
| | | | | | | | | Now that circid_t is 4 bytes long, the default integer promotions will leave it alone when sizeof(int) == 4, which will leave us formatting an unsigned as an int. That's technically undefined behavior. Fixes bug 8447 on bfffc1f0fc7616a25c32da2eb759dade4651659e. Bug not in any released Tor.

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Conflicts: src/or/circuitbuild.c There was a huge-looking conflict in circuitbuild.c, but the only change that had been made to circuitbuild.c since I forked off the split_circuitbuild branch was 17442560c44e8093f9a. So I took the split_circuitbuild version of the conflicting part, and manually re-applied the change from 17442560c44e8093f9a..
