2018-07-05Move literally everything out of src/orNick Mathewson
This commit won't build yet -- it just puts everything in a slightly more logical place. The reasoning here is that "src/core" will hold the stuff that every (or nearly every) tor instance will need in order to do onion routing. Other features (including some necessary ones) will live in "src/feature". The "src/app" directory will hold the stuff needed to have Tor be an application you can actually run. This commit DOES NOT refactor the former contents of src/or into a logical set of acyclic libraries, or change any code at all. That will have to come in the future. We will continue to move things around and split them in the future, but I hope this lays a reasonable groundwork for doing so.

2017-11-16Downgrade evdns warnings about weird replies.Nick Mathewson
evdns is allowed to give us unrecognized object types; it is allowed to give us non-IPv4 answer types, and it is (even) allowed to give us empty answers without an error. Closes ticket 24097.

2017-11-09Audit all of the "is the network turned off" checks.Nick Mathewson
DisableNetwork is a subset of net_is_disabled(), which is (now) a subset of should_delay_dir_fetches(). Some of these changes are redundant with others higher or lower in the call stack. The ones that I think are behavior-relevant are listed in the changes file. I've also added comments in a few places where the behavior is subtle. Fixes bug 12062; bugfix on various versions.

2017-05-26Cleanup MOCK_IMPL (etc) to be findable with etagsNick Mathewson
A fair number of our mock_impl declarations were messed up so that even our special AM_ETAGSFLAGS couldn't find them. This should be a whitespace-only patch.
2017-05-15Fix assertion to actually have a chance of failingNick Mathewson
This assertion can only fail if we mess up some of our other code, but let's try to get it right. Closes 22244.

2017-01-18Initialise DNS TTL for A and AAAA records.Philipp Winter
So far, the TTLs for both A and AAAA records were not initialised, resulting in exit relays sending back the value 60 to Tor clients. This also impacts exit relays' DNS cache -- the expiry time for all domains is set to 60. This fixes <https://bugs.torproject.org/19025>.
2017-01-18DefecTor countermeasure: change server- and client-side DNS TTL clippingNick Mathewson
The server-side clipping now clamps to one of two values, both for what to report, and how long to cache. Additionally, we move some defines to dns.h, and give them better names.

This commit adds or improves the module-level documenation for: buffers.c circuitstats.c command.c connection_edge.c control.c cpuworker.c crypto_curve25519.c crypto_curve25519.h crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c protover.c protover.h reasons.c rephist.c replaycache.c routerlist.c routerparse.c routerset.c statefile.c status.c tor_main.c workqueue.c In particular, I've tried to explain (for each documented module) what each module does, what's in it, what the big idea is, why it belongs in Tor, and who calls it. In a few cases, I've added TODO notes about refactoring opportunities. I've also renamed an argument, and fixed a few DOCDOC comments.
2016-07-04Raise libevent dependency to 2.0.10-stable or newerSebastian Hahn
Only some very ancient distributions don't ship with Libevent 2 anymore, even the oldest supported Ubuntu LTS version has it. This allows us to get rid of a lot of compat code.

2015-01-08Avoid attempts to double-remove edge connections from the DNS resolver.Nick Mathewson
Also, avoid crashing when we attempt to double-remove an edge connection from the DNS resolver: just log a bug warning instead. Fixes bug 14129. Bugfix on 0d20fee2fbd48978, which was in 0.0.7rc1. jowr found the bug. cypherpunks wrote the fix. I added the log message and removed the assert.
