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.

2013-01-14Reject create/begin/etc cells with {circ,stream}ID 0.Nick Mathewson
Otherwise, it's possible to create streams or circuits with these bogus IDs, leading to orphaned circuits or streams, or to ones that can cause bandwidth DOS problems. Fixes bug 7889; bugfix on all released Tors.

2013-01-03Teach cpuworker and others about create_cell_t and friendsNick Mathewson
The unit of work sent to a cpuworker is now a create_cell_t; its response is now a created_cell_t. Several of the things that call or get called by this chain of logic now take create_cell_t or created_cell_t too. Since all cpuworkers are forked or spawned by Tor, they don't need a stable wire protocol, so we can just send structs. This saves us some insanity, and helps p
2013-01-03Massive refactoring of the various handshake typesNick Mathewson
The three handshake types are now accessed from a unified interface; their state is abstracted from the rest of the cpath state, and so on.
2013-01-02Split onion.[ch] into onion{,_fast,_tap}.[ch]Nick Mathewson
I'm going to want a generic "onionskin" type and set of wrappers, and for that, it will be helpful to isolate the different circuit creation handshakes. Now the original handshake is in onion_tap.[ch], the CREATE_FAST handshake is in onion_fast.[ch], and onion.[ch] now handles the onion queue. This commit does nothing but move code and adjust header files.
2012-11-06Allow a v4 link protocol for 4-byte circuit IDs.Nick Mathewson
Implements proposal 214. Needs testing.
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.
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".

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. (That is, all the C except that in src/ext.)

2012-10-05Downgrade "Failed to hand off onionskin" messagesRoger Dingledine
They're typically redundant with the "Your computer is too slow" messages. Fixes bug 7038; bugfix on 0.2.2.16-alpha. (In retrospect, we should have fixed this bug back in ticket 1042.)

Clock skew made this situation way too frequent so we demoted it to "protocol_warn", but when there's an authority, it should really just be warn.

2011-10-28Fix a double-free that would occur on an invalid cert in a CERTS cellNick Mathewson
We would stash the certs in the handshake state before checking them for validity... and then if they turned out to be invalid, we'd give an error and free them. Then, later, we'd free them again when we tore down the connection. Fixes bug 4343; fix on 0.2.3.6-alpha.
