2014-02-06NULL out conns on tlschans when freeing in case channel_run_cleanup() is ↵Andrea Shepard
late; fixes bug 9602

Fixes bug 9731
2013-09-11Try using INT_MAX, not SOMAXCONN, to set listen() backlog.Nick Mathewson
Fall back to SOMAXCONN if INT_MAX doesn't work. We'd like to do this because the actual maximum is overrideable by the kernel, and the value in the header file might not be right at all. All implementations I can find out about claim that this is supported. Fix for 9716; bugfix on every Tor.

(Based on a patch from flupzor; bug #8206)
2013-03-12Don't warn about not sending a socks reply if we get a write errorNick Mathewson
If we get a write error on a SOCKS connection, we can't send a SOCKS reply, now can we? This bug has been here since 36baf7219, where we added the "hey, I'm closing an AP connection but I haven't finished the socks handshake!" message. It's bug 8427.

One is a probably-impossible leak if we fail to sign a consensus; another occurs when we can't look up the user we're trying to chown our sockets to.

2013-02-01Fix serious breakage in connection_handle_write_implNick Mathewson
When we first implemented TLS, we assumed in conneciton_handle_write that a TOR_TLS_WANT_WRITE from flush_buf_tls meant that nothing had been written. But when we moved our buffers to a ring buffer implementation back in 0.1.0.5-rc (!), we broke that invariant: it's possible that some bytes have been written but nothing. That's bad. It means that if we do a sequence of TLS writes that ends with a WANTWRITE, we don't notice that we flushed any bytes, and we don't (I think) decrement buckets. Fixes bug 7708; bugfix on 0.1.0.5-rc
2013-02-01Rename log() to tor_log() for loggingNick Mathewson
This is meant to avoid conflict with the built-in log() function in math.h. It resolves ticket 7599. First reported by dhill. This was generated with the following perl script: #!/usr/bin/perl -w -i -p s/\blog\(LOG_(ERR|WARN|NOTICE|INFO|DEBUG)\s*,\s*/log_\L$1\(/g; s/\blog\(/tor_log\(/g;

2012-11-18Initialize ipv{4,6}_traffic_ok in entry_connection_newNick Mathewson
This one is necessary for sending BEGIN cells with sane flags when self-testing a directory port. All real entry connections were getting their ipv{4,6}_traffic_ok flags set from their listeners, and for begindir entry connections we didn't care, but for directory self-testing, we had a problem. Fixes at least one more case of 7493; if there are more lingering cases of 7493, this might fix them too. Bug not in any released version of Tor.

2012-11-14Add {No,}IPv{4,6}Traffic options to SOCKSPortNick Mathewson
These options are for telling the SOCKSPort that it should allow or not allow connections to IPv4/IPv6 addresses. These aren't implemented yet; this is just the code to read the options and get them into the entrey_connection_t.

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.

2012-10-10Merge branch 'bug7011'Nick Mathewson
Conflicts: src/or/circuitbuild.c The conflict was trivial, since no line of code actually changed in both branches: There was a fmt_addr() that turned into fmt_addrport() in bug7011, and a "if (!n_conn)" that turned into "if (!n_chan)" in master.
2012-10-10Use fmt_addrport where appropriate.David Fifield
This is mostly a conversion from this pattern: log("... %s:%d ...", fmt_and_decorate_addr(&addr), port); to this: log("... %s ...", fmt_addrport(&addr, port)); The output is the same in all cases.
2012-10-10Decorate addresses given to a HTTP CONNECT proxy.David Fifield
This affects the Request-URI and the value of the Host header. RFC 2616 doesn't directly address the formatting of IPv6 addresses, but it delegates some productions to RFC 2396 "Uniform Resource Identifiers (URI): Generic Syntax," which is obsoleted by RFC 3986, which requires square brackets for IPv6 addresses in both places. I tested this with HTTPSProxy 127.0.0.1:8000 Bridge <IPv6 bridge> UseBridges 1 and an Ncat HTTP proxy: ncat --proxy-type http -l 8000 -vvv https://tools.ietf.org/html/rfc2616#section-3.2.1 https://tools.ietf.org/html/rfc2616#section-5.1.2 https://tools.ietf.org/html/rfc2616#section-14.23 https://tools.ietf.org/html/rfc3986#section-3.2.2
