Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types 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 <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	b8fb8264a5	wgengine/netstack: avoid delivering incoming packets to both netstack + host The earlier `eb06ec172f` 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.
