Josh Bleecher Snyder	8a3d52e882	wgengine/magicsock: use mono.Time magicsock makes multiple calls to Now per packet. Move to mono.Now. Changing some of the calls to use package mono has a cascading effect, causing non-per-packet call sites to also switch. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	80a4052593	cmd/tailscale, wgengine, tailcfg: don't assume LastSeen is present [mapver 20] Updates #2107 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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	1a1123d461	wgengine: fix pendopen debug to not track SYN+ACKs, show Node.Online state Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	12b4672add	wgengine: quiet connection failure diagnostics for exit nodes The connection failure diagnostic code was never updated enough for exit nodes, so disable its misleading output when the node it picks (incorrectly) to diagnose is only an exit node. Fixes #1754 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	016de16b2e	net/tstun: rename TUN to Wrapper. The tstun packagen contains both constructors for generic tun Devices, and a wrapper that provides additional functionality. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	588b70f468	net/tstun: merge in wgengine/tstun. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	0994a9f7c4	wgengine{,/magicsock}: fix, improve "tailscale ping" to default routes and subnets e.g. $ tailscale ping 1.1.1.1 exit node found but not enabled $ tailscale ping 10.2.200.2 node "tsbfvlan2" found, but not using its 10.2.200.0/24 route $ sudo tailscale up --accept-routes $ tailscale ping 10.2.200.2 pong from tsbfvlan2 (100.124.196.94) via 10.2.200.34:41641 in 1ms $ tailscale ping mon.ts.tailscale.com pong from monitoring (100.88.178.64) via DERP(sfo) in 83ms pong from monitoring (100.88.178.64) via DERP(sfo) in 21ms pong from monitoring (100.88.178.64) via [2604:a880:4:d1::37:d001]:41641 in 22ms This necessarily moves code up from magicsock to wgengine, so we can look at the actual wireguard config.

Brad Fitzpatrick	1eb95c7e32	net/packet, wgengine{,/filter}: remove net/packet IPProto forwarding consts Only use the ones in types/ipproto now. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	01b90df2fa	net/packet, wgengine/filter: support SCTP Add proto to flowtrack.Tuple. Add types/ipproto leaf package to break a cycle. Server-side ACL work remains. Updates #1516 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	e0f2796b43	wgengine: don't diagnose iOS NWPathMonitor connection probe timeouts Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d76334d2f0	ipn: split LocalBackend off into new ipn/ipnlocal package And move a couple other types down into leafier packages. Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc. Fixes #1181 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	70eb05fd47	wgengine: access flow pending problem with lock held Missed review feedback from just-submitted `d37058af72`.	4 years ago
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>	4 years ago
Brad Fitzpatrick	85e54af0d7	wgengine: on TCP connect fail/timeout, log some clues about why it failed So users can see why things aren't working. A start. More diagnostics coming. Updates #1094	4 years ago
