Jason A. Donenfeld 7cd23e5300 secure_seq: use SipHash in place of MD5 ... This gives a clear speed and security improvement. Siphash is both faster and is more solid crypto than the aging MD5. Rather than manually filling MD5 buffers, for IPv6, we simply create a layout by a simple anonymous struct, for which gcc generates rather efficient code. For IPv4, we pass the values directly to the short input convenience functions. 64-bit x86_64: [ 1.683628] secure_tcpv6_sequence_number_md5# cycles: 99563527 [ 1.717350] secure_tcp_sequence_number_md5# cycles: 92890502 [ 1.741968] secure_tcpv6_sequence_number_siphash# cycles: 67825362 [ 1.762048] secure_tcp_sequence_number_siphash# cycles: 67485526 32-bit x86: [ 1.600012] secure_tcpv6_sequence_number_md5# cycles: 103227892 [ 1.634219] secure_tcp_sequence_number_md5# cycles: 94732544 [ 1.669102] secure_tcpv6_sequence_number_siphash# cycles: 96299384 [ 1.700165] secure_tcp_sequence_number_siphash# cycles: 86015473 Signed-off-by: Jason A.
