2012-12-25Make ECDHE group configurable: 224 for public, 256 for bridges (default)Nick Mathewson
2012-12-06New FallbackDir option to add extra directories for bootstrapingNick Mathewson
This replaces the old FallbackConsensus notion, and should provide a way -- assuming we pick reasonable nodes! -- to give clients suggestions of placs to go to get their first consensus.
2012-12-06Refactor add_trusted_dir_serverNick Mathewson
Now creating a dir_server_t and adding it are separate functions, and there are frontend functions for adding a trusted dirserver and a fallback dirserver.
2012-12-06Rename trusted_dir_server_t to dir_server_t. Automatic renaming.Nick Mathewson
2012-11-14Fix a bug in policy_is_reject_star() that was making IPv4 exits breakNick Mathewson
IPv4-only exits have an implicit "reject [::]/0", which was making policy_is_reject_star() return 1 for them, making us refuse to do hostname lookups. This fix chanes policy_is_reject_star() to ask about which family we meant.
2012-11-14Actually advertise IPv6 exit policies.Nick Mathewson
I have a theory that my tests will work better if the code I'm testing isn't disabled.
2012-11-14Change signature of router_compare_to_my_exit_policy so dns can use itNick Mathewson
Also, fix the function so it actually looks at our ipv6 exit policy.
2012-11-14Rename ipv{4,6}_only to bind_ipv{4,6}_onlyNick Mathewson
This is to avoid confusion with the ipv{4,6}_traffic flags.
2012-11-14Add an IPv6Exit configuration optionNick Mathewson
Don't advertise an IPv6 exit policy, or accept IPv6 exit requests, if IPv6Exit is not true.
2012-11-14Simplest version of server-side IPv6 support (no dns)Nick Mathewson
This is a relatively simple set of changes: we mostly need to remove a few "but not for IPv6" changes. We also needed to tweak the handling of DNS code to generate RESOLVED cells that could get an IPv6 answer in return.
2012-11-14Add IPv6 support to compare_to_addr_to_node_policyNick Mathewson
2012-11-14Better policy support for IPv6Nick Mathewson
Now, "accept *:80" means "accept all addresses on port 80", and not just IPv4. For just v4, say "accept *4:80"; for just v6 say "accept *6:80". We can parse these policies from torrc just fine, and we should be successfully keeping them out of descriptors for now. We also now include appropriate IPv6 addresses in "reject private:*"
2012-11-04Merge remote-tracking branch 'linus/bug5053-bug5055'Nick Mathewson
Conflicts: src/or/geoip.c
2012-10-20Separate IPv4 and IPv6 geoip file loading.Linus Nordberg
Also add IPv6 geoip file digest to extra info. Also also, add support for IPv6 addresses in control command "ip-to-country".
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.) The resulting script was: ============================== s/(?<![A-Za-z0-9_])_address(?![A-Za-z0-9_])/address_/g; s/(?<![A-Za-z0-9_])_aes_fill_buf(?![A-Za-z0-9_])/aes_fill_buf_/g; s/(?<![A-Za-z0-9_])_AllowInvalid(?![A-Za-z0-9_])/AllowInvalid_/g;

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.

2012-08-23Move ipv6_preferred from routerinfo_t to node_t.Linus Nordberg
Move extend_info_from_router() from circuitbuild.c to router.c and make it static. Add get_configured_bridge_by_orports_digest() and have get_configured_bridge_by_routerinfo() and node_is_a_configured_bridge() use it. We now consider all OR ports of a bridge when looking for it. Move node_get_*_orport to nodelist.c. Fix a cut'n'paste error in header of nodelist.h. Add node_assert_ok(). Add router_get_all_orports(). It's duplicating code from node_get_all_orports(). Worth fixing at the cost of complicating the API slightly?

2012-08-09Don't infer we have a FooPort from the presence of a FooPort lineNick Mathewson
Thanks to the changes we started making with SocksPort and friends in 0.2.3.3-alpha, any of our code that did "if (options->Sockport)" became wrong, since "SocksPort 0" would make that test true whereas using the default SocksPort value would make it false. (We didn't actually do "if (options->SockPort)" but we did have tests for TransPort. When we moved DirPort, ORPort, and ControlPort over to the same system in 0.2.3.9-alpha, the problem got worse, since our code is littered with checks for DirPort and ORPort as booleans. This code renames the current linelist-based FooPort options to FooPort_lines, and adds new FooPort_set options which get set at parse-and-validate time on the or_options_t. FooPort_set is true iff we will actually try to open a listener of the given type. (I renamed the FooPort options rather than leave them alone so that every previous user of a FooPort would need to get inspected, and so that any new code that forgetfully uses FooPort will need fail to compile.) Fix for bug 6507.

Also, try to resolve some doxygen issues. First, define a magic "This is doxygen!" macro so that we take the correct branch in various #if/#else/#endifs in order to get the right documentation. Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.
2012-05-24Warn and ignore the MyFamily setting if BridgeRelay is also setNick Mathewson
Roger explains at http://archives.seul.org/tor/talk/Nov-2011/msg00209.html : "If you list your bridge as part of your family in the relay descriptor, then everybody can learn your bridge fingerprint, and they can look up your bridge's descriptor (and thus location) at the bridge directory authority." Now, we can't stop relays from listing bridges, but we can warn when we notice a bridge listing anybody, which might help some. This fixes bug 4657; it's a fix on 0.2.0.3-alpha, where bridges were first introduced.

2012-05-10Fix O(n^2) performance when parsing a big pile of extrainfosNick Mathewson
We were doing an O(n) strlen in router_get_extrainfo_hash() for every one we tried to parse. Instead, have router_get_extrainfo_hash() take the length of the extrainfo as an argument, so that when it's called from extrainfo_parse_from_string(), it doesn't do a strlen() over the whole pile of extrainfos.
2012-05-03Ignore [::] when building descriptors.Linus Nordberg
This is how IPv6 says "0.0.0.0" and something we will have to translate into a globally reachable address before putting it in a descriptor. The fix is a short term solution until a real one is implemented. Closes #5146.

Instead of checking for 'rejected' and calling everything else okay, let's check for 'outdated' and call everythign else a problem. This way we don't risk missing future errors so much. When logging a message that _looks_ like an error message at info, we should mention that it isn't really a problem.
