| * | | | | Increase link_proto field to 2 bytesNick Mathewson2013-03-11
| | |_|/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This should have been 2 bytes all along, since version numbers can be 16 bits long. This isn't a live bug, since the call to is_or_protocol_version_known in channel_tls_process_versions_cell will reject any version number not in the range 1..4. Still, let's fix this before we accidentally start supporting version 256. Reported pseudonymously. Fixes bug 8062; bugfix on 0.2.0.10-alpha -- specifically, on commit 6fcda529, where during development I increased the width of a version to 16 bits without changing the type of link_proto.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In addition to rejecting them post-hoc, avoid picking them in the first place. This makes us less likely to decide that we can't add guards at all.

| | |_|/ / | |/| | | | | | | | | | | | | | | | | | | | | | | Apparently something in the directory guard code made it possible for the same node to get added as a guard over and over when there were no actual running guard nodes.

| * | | Refactor storing of measured_bw versus Unmeasured=1.Nick Mathewson2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the measured_bw field and the has_measured_bw field into vote_routerstatus_t, since only votes have 'Measured=XX' set on their weight line. I also added a new bw_is_unmeasured flag to routerstatus_t to represent the Unmeasured=1 flag on a w line. Previously, I was using has_measured_bw for this, which was quite incorrect: has_measured_bw means that the measured_bw field is set, and it's probably a mistake to have it serve double duty as meaning that 'baandwidth' represents a measured value. While making this change,I also found a harmless but stupid bug in dirserv_read_measured_bandwidths: It assumes that it's getting a smartlist of routerstatus_t, when really it's getting a smartlist of vote_routerstatus_t. C's struct layout rules mean that we could never actually get an error because of that, but it's still quite incorrect. I fixed that, and in the process needed to add two more sorting and searching helpers. Finally, I made the Unmeasured=1 flag get parsed. We don't use it for anything yet, but someday we might. This isn't complete yet -- the new 2286 unit test doesn't build.
| * | | Tweak consensus method 17 based on arma's commentsNick Mathewson2013-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of capping whenever a router has fewer than 3 measurements, we cap whenever a router has fewer than 3 measurements *AND* there are at least 3 authorities publishing measured bandwidths. We also generate bandwidth lines with a new "Unmeasured=1" flag, meaning that we didn't have enough observations for a node to use measured bandwidth values in the authority's input, whether we capped it or not.

| * | | When excluding nodes by country, exclude {??} and {A1} tooNick Mathewson2013-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is ticket 7706, reported by "bugcatcher." The rationale here is that if somebody says 'ExcludeNodes {tv}', then they probably don't just want to block definitely Tuvaluan nodes: they also want to block nodes that have unknown country, since for all they know such nodes are also in Tuvalu. This behavior is controlled by a new GeoIPExcludeUnknown autobool option. With the default (auto) setting, we exclude ?? and A1 if any country is excluded. If the option is 1, we add ?? and A1 unconditionally; if the option is 0, we never add them. (Right now our geoip file doesn't actually seem to include A1: I'm including it here in case it comes back.) This feature only takes effect if you have a GeoIP file. Otherwise you'd be excluding every node.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | Use a TAILQ, not a singly-linked queue, for the onion queue.Nick Mathewson2013-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes removing items from the middle of the queue into an O(1) operation, which could prove important as we let onionqueues grow longer. Doing this actually makes the code slightly smaller, too.
| * | | Eliminate MaxOnionsPending; replace it with MaxOnionQueueDelayNick Mathewson2013-01-03

So instead, let's measure how long it takes to process onionskins (sampling them once we have a big number), and then limit the queue based on its expected time to finish. This change is extra-necessary for ntor, since there is no longer a reasonable way to set MaxOnionsPending without knowing what mix of onionskins you'll get. This patch also reserves 1/3 of the onionskin spots for ntor handshakes, on the theory that TAP handshakes shouldn't be allowed to starve their speedier cousins. We can change this later if need be. Resolves 7291.

| |/ / / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | In general, if we tried to use a circ for a stream, but then decided to place that stream on a different circuit, we need to probe the original circuit before deciding it was a "success". We also need to do the same for cannibalized circuits that go unused.

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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As elsewhere, it makes sense when adding or extending a cell type to actually make the code to parse it into a separate tested function.
