| * Don't infer we have a FooPort from the presence of a FooPort lineNick Mathewson2012-08-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Bug 6475: Explicitly track our path bias state.Mike Perry2012-08-15
|/ | | | | | This is done to avoid spurious warns. Additional log lines are also added to try to track down the codepaths where we are somehow overcounting success counts.
* Defend against entry node path bias attacksMike Perry2012-06-14
| | | | | | | | | | | | | The defense counts the circuit failure rate for each guard for the past N circuits. Failure is defined as the ability to complete a first hop, but not finish completing the circuit all the way to the exit. If the failure rate exceeds a certain amount, a notice is emitted. If it exceeds a greater amount, a warn is emitted and the guard is disabled. These values are governed by consensus parameters which we intend to tune as we perform experiments and statistical simulations.

| * An attempt at bug3940 and making AllowDotExit 0 work with MapAddressNick Mathewson2012-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This time, I follow grarpamp's suggestion and move the check for .exit+AllowDotExit 0 to the top of connection_ap_rewrite_and_attach, before any rewriting occurs. This way, .exit addresses are forbidden as they arrive from a socks connection or a DNSPort request, and not otherwise. It _is_ a little more complicated than that, though. We need to treat any .exit addresses whose source is TrackHostExits as meaning that we can retry without that exit. We also need to treat any .exit address that comes from an AutomapHostsOnResolve operation as user-provided (and thus forbidden if AllowDotExits==0), so that transitioning from AllowDotExits==1 to AllowDotExits==0 will actually turn off automapped .exit addresses.

Second, add in a few grouping @{ and @} entries in order to get some variables and fields to get grouped together.

* | Bump _WIN32_WINNT to 0x0501 throughout the codeNick Mathewson2012-05-14
| | | | | | | | | | | | | | | | | | This tells the windows headers to give us definitions that didn't exist before XP -- like the ones that we need for IPv6 support. See bug #5861. We didn't run into this issue with mingw, since mingw doesn't respect _WIN32_WINNT as well as it should for some of its definitions.

| * Twiddle ROUTER_{MAX_COSMETIC_TIME_DIFFERENCE,MAX_AGE_TO_PUBLISH}Nick Mathewson2012-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is ticket 2479. Roger's original explanation was: We have a series of bugs where relays publish a descriptor within 12 hours of their last descriptor, but the authorities drop it because it's not different "enough" from the last one and it's too close to the last one. The original goal of this idea was to a) reduce the number of new descriptors authorities accept (and thus have to store) and b) reduce the total number of descriptors that clients and mirrors fetch. It's a defense against bugs where relays publish a new descriptor every minute. Now that we're putting out one consensus per hour, we're doing better at the total damage that can be caused by 'b'. There are broader-scale design changes that would help here, and we've had a trac entry open for years about how relays should recognize that they're not in the consensus, or recognize when their publish failed, and republish sooner. In the mean time, I think we should change some of the parameters to make the problem less painful.

New type tor_addr_port_t holding an IP address and a TCP/UDP port. New flag in routerinfo_t, ipv6_preferred. This should go in the node_t instead but not now. Replace node_get_addr() with - node_get_prim_addr() for primary address, i.e. IPv4 for now - node_get_pref_addr() for preferred address, IPv4 or IPv6. Rename node_get_addr_ipv4h() node_get_prim_addr_ipv4h() for consistency. The primary address will not allways be an IPv4 address. Same for node_get_orport() -> node_get_prim_orport(). Rewrite node_is_a_configured_bridge() to take all OR ports into account. Extend argument list to extend_info_from_node and extend_info_from_router with a flag indicating if we want to use the routers primary address or the preferred address. Use the preferred address in as few situtations as possible for allowing clients to connect to bridges over IPv6.
