cathugger	ca01daa89a	ip: support DCCP and UDP-Lite, TCP chksum twx; tun: more filtering	2018-10-15 00:56:14 +03:00
cathugger	d0c35803a5	tun+ip: filter packets at destination, drop instead of truncating	2018-10-13 21:57:31 +03:00
cathugger	360ccc33de	ip: more one's complement math improvements	2018-10-13 21:31:50 +03:00
cathugger	4d5f5fecfa	ip: make things fragmentation-aware, cleanup UDP handling; also format ... one's complement math is pretty fun	2018-10-13 18:42:47 +03:00
cathugger	18c20396b6	add {h,n}uint16_t types, optimize TCP/UDP checksuming ... use static functions + switch instead of lambda functions + map.	2018-10-12 04:38:16 +00:00
cathugger	71c9965471	ip: code cleanups and compatibility improvements ... do not assume that packets come with address zero-ed, older clients don't do that. they don't modify checksum either, therefore we should be able to get correct checksum if we use deltachksum with old and new addresses.	2018-10-10 21:41:53 +00:00
