2017-11-10allowedips: rename from routingtableJason A. Donenfeld
Makes it more clear that this _not_ a routing table replacement. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2017-11-02global: revert checkpatch.pl changesJason A. Donenfeld
These changes were suggested by checkpatch.pl, but actually cause big problems depending on the options. Revert. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-10-31global: infuriating kernel iterator styleJason A. Donenfeld
One types: for (i = 0 ... So one should also type: for_each_obj (obj ... But the upstream kernel style guidelines are insane, and so we must instead do: for_each_obj(obj ... Ugly, but one must choose his battles wisely. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2017-10-31peer: store total number of peers instead of iteratingJason A. Donenfeld
This is faster, since it means adding a new peer is O(1) instead of O(n). It's also safe to do because we're holding the device_update_lock on both the ++ and the --. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2017-10-31global: accept decent check_patch.pl suggestionsJason A. Donenfeld

2017-10-02noise: use spinlock for rotating keysJason A. Donenfeld
This should only really be contended in extremely exceptional cases, so changing from a mutex to a spinlock is likely fine. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-09-18queue: entirely rework parallel systemJason A. Donenfeld
This removes our dependency on padata and moves to a different mode of multiprocessing that is more efficient. This began as Samuel Holland's GSoC project and was gradually reworked/redesigned/rebased into this present commit, which is a combination of his initial contribution and my subsequent rewriting and redesigning.

2017-04-04locking: always use _bhJason A. Donenfeld
All locks are potentially between user context and softirq, which means we need to take the _bh variant. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-12-23cookies: use xchacha20poly1305 instead of chacha20poly1305Jason A. Donenfeld
This allows us to precompute the blake2s calls and save cycles, since hchacha is fast. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2016-08-02c: specify static array size in function paramsJason A. Donenfeld
The C standard states: A declaration of a parameter as ``array of type'' shall be adjusted to ``qualified pointer to type'', where the type qualifiers (if any) are those specified within the [ and ] of the array type derivation. If the keyword static also appears within the [ and ] of the array type derivation, then for each call to the function, the value of the corresponding actual argument shall provide access to the first element of an array with at least as many elements as specified by the size expression. By changing void func(int array[4]) to void func(int array[static 4]), we automatically get the compiler checking argument sizes for us, which is quite nice. Signed-off-by: Jason A.
