2014-02-12Siphash-2-4 is now our hash in nearly all cases.Nick Mathewson
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.

2013-10-02Fix a bug in our bug 9776 fix.Nick Mathewson
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.

2013-08-22Separate mutable/const accessors for circuit_build_timesNick Mathewson
(These have proved invaluable for other global accessors.)
2013-08-22Make circ_times static and add accessor functions.vagrant
Change the global circ_times to a static variable and use accessor functions throughout the code, instead of accessing it directly.

2013-07-23Fix bug9309, and n_noncanonical count/continue codeNick Mathewson
When we moved channel_matches_target_addr_for_extend() into a separate function, its sense was inverted from what one might expect, and we didn't have a ! in one place where we should have. Found by skruffy.

2013-06-17Fix bug 9082: avoid leak when freeing destroy cell queuesNick Mathewson
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.
2013-06-13Add destroy balance tracking and logging to circuitmuxAndrea Shepard
2013-06-13Implementation of a fix for bug 7912Nick Mathewson
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.

Instead, drop the cell. Fixes another case of bug 7350; bugfix on 0.2.4.4-alpha
2013-03-10Fix 8447: use %u to format circid_t.Nick Mathewson
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.

2012-10-22Merge branch 'split_circuitbuild'Nick Mathewson
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..
2012-10-17Fix a bug in channel_dump_statisticsNick Mathewson
We were calling channel_get_actual_remote_descr() before we used the output of a previous channel_get_canonical_remote_descr(), thus invalidating its output.

2012-10-17Restore the 'address' value of tunneled connectionsNick Mathewson
When we merged the channel code, we made the 'address' field of linked directory connections created with begindir (and their associated edge connections) contain an address:port string, when they should only have contained the address part. This patch also tweaks the interface to the get_descr method of channels so that it takes a set of flags rather than a single flag.

2012-10-12Rename all reserved C identifiers we definedNick Mathewson
For everything we declare that starts with _, make it end with _ instead. This is a machine-generated patch. To make it, start by getting the list of reserved identifiers using: git ls-tree -r --name-only HEAD | grep '\.[ch]$' | \ xargs ctags --c-kinds=defglmpstuvx -o - | grep '^_' | \ cut -f 1 | sort| uniq You might need gnu ctags. Then pipe the output through this script: ============================== use strict; BEGIN { print "#!/usr/bin/perl -w -i -p\n\n"; } chomp; next if ( /^__attribute__/ or /^__func__/ or /^_FILE_OFFSET_BITS/ or /^_FORTIFY_SOURCE/ or /^_GNU_SOURCE/ or /^_WIN32/ or /^_DARWIN_UNLIMITED/ or /^_FILE_OFFSET_BITS/ or /^_LARGEFILE64_SOURCE/ or /^_LFS64_LARGEFILE/ or /^__cdecl/ or /^__attribute__/ or /^__func__/ or /^_WIN32_WINNT/); my $ident = $_; my $better = $ident; $better =~ s/^_//; $better = "${better}_"; print "s/(?<![A-Za-z0-9_])$ident(?![A-Za-z0-9_])/$better/g;\n"; ============================== Then run the resulting script on all the files you want to change.
