2017-08-08hashtables: allow up to 2^{20} peers per interfaceJason A. Donenfeld
This allows for nearly 1 million peers per interface, which should be more than enough. If needed later, this number could easily be increased beyond this. We also increase the size of the hashtables to accommodate this upper bound. In the future, it might be smart to dynamically expand the hashtable instead of this hard coded compromise value between small systems and large systems. Ongoing work includes figuring out the most optimal scheme for these hashtables and for the insertion to mask their order from timing inference. 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>
