2014-11-17Remove Support022HiddenServicesNick Mathewson
This has been already disabled in the directory consensus for a while; it didn't seem to break anything. Finally closes #7803.

2014-11-10Fix: don't report timeout when closing parallel intro pointsDavid Goulet
When closing parallel introduction points, the given reason (timeout) was actually changed to "no reason" thus when the circuit purpose was CIRCUIT_PURPOSE_C_INTRODUCE_ACK_WAIT, we were reporting an introduction point failure and flagging it "unreachable". After three times, that intro point gets removed from the rend cache object. In the case of CIRCUIT_PURPOSE_C_INTRODUCING, the intro point was flagged has "timed out" and thus not used until the connection to the HS is closed where that flag gets reset. This commit adds an internal circuit reason called END_CIRC_REASON_IP_NOW_REDUNDANT which tells the closing circuit mechanism to not report any intro point failure. This has been observed while opening hundreds of connections to an HS on different circuit for each connection. This fix makes this use case to work like a charm. Fixes #13698.

Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?

2014-09-16clients now send correct address for rendezvous pointRoger Dingledine
Clients now send the correct address for their chosen rendezvous point when trying to access a hidden service. They used to send the wrong address, which would still work some of the time because they also sent the identity digest of the rendezvous point, and if the hidden service happened to try connecting to the rendezvous point from a relay that already had a connection open to it, the relay would reuse that connection. Now connections to hidden services should be more robust and faster. Also, this bug meant that clients were leaking to the hidden service whether they were on a little-endian (common) or big-endian (rare) system, which for some users might have reduced their anonymity. Fixes bug 13151; bugfix on 0.2.1.5-alpha.
2014-08-15Autoconvert most circuit-list iterations to smartlist iterationsNick Mathewson
Breaks compilation. Used this coccinelle script: @@ identifier c; typedef circuit_t; iterator name TOR_LIST_FOREACH; iterator name SMARTLIST_FOREACH_BEGIN; statement S; @@ - circuit_t *c; ... - TOR_LIST_FOREACH(c, \(&global_circuitlist\|circuit_get_global_list()\), head) + SMARTLIST_FOREACH_BEGIN(circuit_get_global_list(), circuit_t *, c) S + SMARTLIST_FOREACH_END(c);

If somebody's excludenodes settings are keeping their hidden service connections from working, they should probably get notified about it.

2014-01-24Apply StrictNodes to hidden service directories earlyNick Mathewson
Previously, we would sometimes decide in directory_get_from_hs_dir() to connect to an excluded node, and then later in directory_initiate_command_routerstatus_rend() notice that it was excluded and strictnodes was set, and catch it as a stopgap. Additionally, this patch preferentially tries to fetch from non-excluded nodes even when StrictNodes is off. Fix for bug #10722. Bugfix on 0.2.0.10-alpha (the v2 hidserv directory system was introduced in e136f00ca). Reported by "mr-4".

2013-09-20Get ready to stop sending timestamps in INTRODUCE cellsNick Mathewson
For now, round down to the nearest 10 minutes. Later, eliminate entirely by setting a consensus parameter. (This rounding is safe because, in 0.2.2, where the timestamp mattered, REND_REPLAY_TIME_INTERVAL was a nice generous 60 minutes.)

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.
2013-01-18Implement Path use bias accounting.Mike Perry
Path use bias measures how often we can actually succeed using the circuits we actually try to use. It is a subset of path bias accounting, but it is computed as a separate statistic because the rate of client circuit use may vary depending on use case.

2012-11-08Add and use and unlikely-to-be-eliminated memwipe()Nick Mathewson
Apparently some compilers like to eliminate memset() operations on data that's about to go out-of-scope. I've gone with the safest possible replacement, which might be a bit slow. I don't think this is critical path in any way that will affect performance, but if it is, we can work on that in 0.2.4. Fixes bug 7352.
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.

2012-09-17Avoid sign-extending when computing rend auth type.Nick Mathewson
Right-shifting negative values has implementation-defined behavior. On all the platforms we work on right now, the behavior is to sign-extend the input. That isn't what we wanted in auth_type_val = (descriptor_cookie_tmp[16] >> 4) + 1; Fix for 6861; bugfix on 0.2.1.5-alpha; reported pseudonymously. The broken behavior didn't actually hurt anything, I think, since the only way to get sign-extension to happen would be to have the top bit of descriptor_cookie_tmp[16] set, which would make the value of descriptor_cookie_tmp[16] >> 4 somewhere between 0b11111111 and 0b11111000 (that is, between -1 and -8). So auth_type_val would be between -7 and 0. And the immediate next line does: if (auth_type_val < 1 || auth_type_val > 2) { So the incorrectly computed auth_type_val would be rejected as invalid, just as a correctly computed auth_type_val would be. Still, this stuff shouldn't sit around the codebase.

2012-09-12Fix directory self-testing logicNick Mathewson
When I removed version_supports_begindir, I accidentally removed the mechanism we had been using to make a directory cache self-test its directory port. This caused bug 6815, which caused 6814 (both in 0.2.4.2-alpha). To fix this bug, I'm replacing the "anonymized_connection" argument to directory_initiate_command_* with an enumeration to say how indirectly to connect to a directory server. (I don't want to reinstate the "version_supports_begindir" argument as "begindir_ok" or anything -- these functions already take too many arguments.) For safety, I made sure that passing 0 and 1 for 'indirection' gives the same result as you would have gotten before -- just in case I missed any 0s or 1s.
