all: adapt to opaque netaddr types

2021-05-16T21:52:00Z

This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w*(.*)\.Port = (.*) -> $1 = $1.WithPort($2) \w*(.*)\.IP = (.*) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder

wgengine/netstack: avoid delivering incoming packets to both netstack + host

2021-05-06T13:43:16Z

The earlier eb06ec172f1d984bb87c589da1dd2d3f15dc6d82 fixed the flaky SSH issue (tailscale/corp#1725) by making sure that packets addressed to Tailscale IPs in hybrid netstack mode weren't delivered to netstack, but another issue remained: All traffic handled by netstack was also potentially being handled by the host networking stack, as the filter hook returned "Accept", which made it keep processing. This could lead to various random racey chaos as a function of OS/firewalls/routes/etc. Instead, once we inject into netstack, stop our caller's packet processing. Signed-off-by: Brad Fitzpatrick
