Brad Fitzpatrick	d37058af72	net/packet: add some more TSMP packet reject reasons and MaybeBroken bit ... Unused for now, but I want to backport this commit to 1.4 so 1.6 can start sending these and then at least 1.4 logs will stringify nicely.

Brad Fitzpatrick	b560386c1a	net/packet, wgengine, tstun: add inter-node TSMP protocol for connect errors ... This adds a new IP Protocol type, TSMP on protocol number 99 for sending inter-tailscale messages over WireGuard, currently just for why a peer rejects TCP SYNs (ACL rejection, shields up, and in the future: nothing listening, something listening on that port but wrong interface, etc) Updates #1094 Updates tailscale/corp#1185 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2021-01-15 14:03:57 -08:00
