2017-11-14curve25519-neon: compile in thumb modeJason A. Donenfeld
In thumb mode, it's not possible to use sp as an operand of and, so we have to muck around with r3 as a scratch register. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-11-11curve25519: reject deriving from NULL private keysJason A. Donenfeld
These aren't actually valid 25519 points pre-normalization, and doing this is required to make unsetting private keys based on all zeros. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
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>
2017-11-10netlink: make sure we reserve space for NLMSG_DONEJason A. Donenfeld
Otherwise, if messages pack really close together, we'll exceed the size of the sk_buff and return ENOBUFS. I suspect this has been the cause of a lot of weird bugs that people just worked around by increasing the receive buffer size. This actually addresses the root cause. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

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>

2017-10-31device: only take reference if netns is differentJason A. Donenfeld
If we take two references, the namespace and the device are never freed in the usual manner. We should thus only take a reference to another namespace when it is a different namespace from our own. 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>
2017-10-31peer: get rid of peer_for_each magicJason A. Donenfeld
Since the peer list is protected by the device_update_lock, and since items are removed from the peer list before putting their final reference, we don't actually need to take a reference when iterating. This allows us to simplify the macro considerably. Suggested-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2017-10-31netns: use read built-in instead of ncat hack for dmesgJason A. Donenfeld
This misses lines that are greater than 128 bytes -- read returns -EINVAL -- but the lines we care about anyway are less than that, so we simply keep looping and skip the bad reads when this happens. Not ideal, but probably the best we can do in pure bash. And, importantly, it's much better than streaming this over a TCP socket, which was an even uglier hack. Signed-off-by: Jason A.
