2014-02-07Remove a needless check in channel_tls_handle_incomingNick Mathewson
This patch removes an "if (chan)" that occurred at a place where chan was definitely non-NULL. Having it there made some static analysis tools conclude that we were up to shenanigans. This resolves #9979.

2013-12-09Remove a check in channeltls.c that could never fail.Nick Mathewson
We were checking whether a 8-bit length field had overflowed a 503-byte buffer. Unless somebody has found a way to store "504" in a single byte, it seems unlikely. Fix for 10313 and 9980. Based on a pach by Jared L Wong. First found by David Fifield with STACK.

2013-08-21Make bridges send AUTH_CHALLENGE cellsNick Mathewson
The spec requires them to do so, and not doing so creates a situation where they can't send-test because relays won't extend to them because of the other part of bug 9546. Fixes bug 9546; bugfix on 0.2.3.6-alpha.
2013-08-20Send NETINFO on receiving a NETINFO if we have not yet sent one.Nick Mathewson
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.

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.

2013-03-11Fix a framing bug when reading versions from a versions cell.Nick Mathewson
Our ++ should have been += 2. This means that we'd accept version numbers even when they started at an odd position. This bug should be harmless in practice for so long as every version number we allow begins with a 0 byte, but if we ever have a version number starting with 1, 2, 3, or 4, there will be trouble here. Fix for bug 8059, reported pseudonymously. Bugfix on 0.2.0.10-alpha -- specifically, commit 6fcda529, where during development I increased the width of a version to 16 bits without changing the loop step.

2012-10-23Fix a remotely triggerable assertion failure (CVE-2012-2250)Nick Mathewson
If we completed the handshake for the v2 link protocol but wound up negotiating the wong protocol version, we'd become so confused about what part of the handshake we were in that we'd promptly die with an assertion. This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha. All servers running that version or later should really upgrade. Bug and fix from "some guy from France." I tweaked his code slightly to make it log the IP of the offending node, and to forward-port it to 0.2.4.

2012-10-17Discard extraneous renegotiation attempts in the v3 link protocolNick Mathewson
Failure to do so left us open to a remotely triggerable assertion failure. Fixes CVE-2012-2249; bugfix on 0.2.3.6-alpha. Reported by "some guy from France". This patch is a forward-port to 0.2.4, to work with the new channel logic.
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.

2012-10-10Remove variables; fix gcc 4.7 warningsNick Mathewson
My GCC warns when variables are assigned to but never used. There were a few like that in the 6816/6465 branches.

2012-10-09Add magic number for type-checking channel castsAndrea Shepard
2012-10-09Set reason_for_closing when erroring out of channel_tls_connect()Andrea Shepard
2012-10-09Split channel_t into channel_t and channel_listener_t; get rid of that big unionAndrea Shepard

2012-10-08s/channel_request_close()/channel_mark_for_close()/g for consistencyAndrea Shepard

2012-10-08Use U64_FORMAT/U64_PRINTF_ARG rather than %lu for channel_tAndrea Shepard
2012-10-08Check return value from connection_or_connect() in channel_tls_connect()Andrea Shepard
It's possible for connection_or_connect() to fail and return NULL after it sets tlschan->conn, so not checking leaves a channel hanging around in CHANNEL_STATE_OPENING with a pointer to a freed or_connection_t forever.
