Closes ticket 25291.
2018-04-05Switch to use should_record_bridge_info()Neel Chauhan
Both in geoip_note_client_seen() and options_need_geoip_info(), switch from accessing the options directly to using the should_record_bridge_info() helper function. Fixes #25290 Signed-off-by: David Goulet <dgoulet@torproject.org>

2018-02-15man: Update the CircuitPriorityHalflife entryDavid Goulet
The behavior has changed slightly in the previous commits. Signed-off-by: David Goulet <dgoulet@torproject.org>
2018-02-15cmux: Rename cell_ewma_set_scale_factor()David Goulet
It is rename to something more meaningful that explains what it does exactly which is sets the EWMA options (currently only one exists). The new name is cmux_ewma_set_options(). Also, remove a public function from circuitmux_ewma.h that is only used in the C file. Make it static inline as well. Signed-off-by: David Goulet <dgoulet@torproject.org>
2018-02-15cmux: Make EWMA policy mandatoryDavid Goulet
To achieve this, a default value for the CircuitPriorityHalflife option was needed. We still look in the options and then the consensus but in case no value can be found, the default CircuitPriorityHalflifeMsec=30000 is used. It it the value we've been using since 0.2.4.4-alpha. This means that EWMA, our only policy, can not be disabled anymore fallbacking to the round robin algorithm. Unneeded code to control that is removed in this commit. Part of #25268 Signed-off-by: David Goulet <dgoulet@torproject.org>
2018-02-07Remove anything related to the old SocksSockets optionDavid Goulet
At this commit, the SocksSocketsGroupWritable option is renamed to UnixSocksGroupWritable. A deprecated warning is triggered if the old option is used and tor will use it properly. Fixes #24343 Signed-off-by: David Goulet <dgoulet@torproject.org>

2018-01-30dos: Make circuit rate limit per second, not tenths anymoreDavid Goulet
Because this touches too many commits at once, it is made into one single commit. Remove the use of "tenths" for the circuit rate to simplify things. We can only refill the buckets at best once every second because of the use of approx_time() and our token system is set to be 1 token = 1 circuit so make the rate a flat integer of circuit per second. Signed-off-by: David Goulet <dgoulet@torproject.org>
2018-01-30dos: Initial code of Denial of Service mitigationDavid Goulet
This commit introduces the src/or/dos.{c|h} files that contains the code for the Denial of Service mitigation subsystem. It currently contains basic functions to initialize and free the subsystem. They are used at this commit. The torrc options and consensus parameters are defined at this commit and getters are implemented. Signed-off-by: David Goulet <dgoulet@torproject.org>

2017-12-23Make the default DirAuthorityFallbackRate 0.1teor
This makes clients on the public tor network prefer to bootstrap off fallback directory mirrors. This is a follow-up to 24679, which removed weights from the default fallbacks. Implements ticket 24681.
2017-12-16Add MainloopStats option.Alexander Færøy
This patch adds support for MainloopStats that allow developers to get main event loop statistics via Tor's heartbeat status messages. The new status log message will show how many succesful, erroneous, and idle event loop iterations we have had. See: https://bugs.torproject.org/24605

2017-12-11Add support for Android's logging subsystem.Alexander Færøy
This patch adds support for Android's logging subsystem in Tor. When debugging Android applications it is useful to be able to collect information about the application running on the platform via the various system services that is available on the platform. This patch allows you to add "Log notice android" to your torrc and have Tor send everything above and including the notice severity to Android's ring buffer which can be inspected using the 'adb logcat' program. See: https://bugs.torproject.org/24362
2017-12-11Restructure log initilization function to allow multiple backends without ↵Alexander Færøy
arguments. This patch ensures that we more easily can extend our log backends that does not take any additional argument other than a single keyword. This patch is mostly reindentation of some code which is why it is split out into its own patch. See: https://bugs.torproject.org/24362

Fortunately, use_cached_ipv4_answers was already 0, so we wouldn't actually use this info, but it's best not to have it. Fixes bug 24050; bugfix on 0.2.6.3-alpha
