David Anderson	d99f5b1596	net/dns/resolver: factor the resolver out into a sub-package. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Naman Sood	31c7745631	wgengine/netstack: stop re-adding IPs registered by active TCP connections (#1629 ) Signed-off-by: Naman Sood <mail@nsood.in>	4 years ago
Brad Fitzpatrick	7f03c0f8fe	wgengine/wgcfg/nmcfg: reduce some logging when a /0 route skipped Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	7b907615d5	wgengine/wgcfg/nmcfg: remove dead code The call to appendEndpoint updates cpeer.Endpoints. Then it is overwritten in the next line. The only errors from appendEndpoint occur when the host/port pair is malformed, but that cannot happen. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	36a85e1760	wgengine/magicsock: don't call t.Fatal in magicStack.IP It can end up executing an a new goroutine, at which point instead of immediately stopping test execution, it hangs. Since this is unexpected anyway, panic instead. As a bonus, it makes call sites nicer and removes a kludge comment. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	4c83bbf850	wgengine: add IsNetstack func and test So we have a documented & tested way to check whether we're in netstack mode. To be used by future commits. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	41e4e02e57	net/{packet,tstun}: send peerapi port in TSMP pongs For discovery when an explicit hostname/IP is known. We'll still also send it via control for finding peers by a list. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	a4c679e646	wgengine/monitor: on wall time jump, synthesize network change event ... to force rebinds of TCP connections Fixes #1555 Updates tailscale/felicity#4 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	07bf4eb685	wgengine: rename Fake to RespondToPing. "Fake" doesn't mean a lot any more, given that many components of the engine can be faked out, including in valid production configurations like userspace-networking. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0fb738760f	wgengine: make Tun optional again, default to fake. This makes setup more explicit in prod codepaths, without requiring a bunch of arguments or helpers for tests and userspace mode. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	e18c3a7d84	wgengine: optimize isLocalAddr a bit On macOS/iOS, this removes a map lookup per outgoing packet. Noticed it while reading code, not from profiles, but can't hurt.

Josh Bleecher Snyder	4954fbfda6	wgengine: extend TestWatchdog timeout on macOS This works around the close syscall being slow. We can revert this if we find a fix or if Apple makes close fast again. Signed-off-by: Josh Bleecher Snyder <josh@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

Brad Fitzpatrick	7f174e84e6	net/interfaces: remove mutating methods, add EqualFiltered instead Now callers (wgengine/monitor) don't need to mutate the state to remove boring interfaces before calling State.Equal. Instead, the methods to remove boring interfaces from the State are removed, as is the reflect-using Equal method itself, and in their place is a new EqualFiltered method that takes a func predicate to match interfaces to compare. And then the FilterInteresting predicate is added for use with EqualFiltered to do the job that that wgengine/monitor previously wanted. Now wgengine/monitor can keep the full interface state around, including the "boring" interfaces, which we'll need for peerapi on macOS/iOS to bind to the interface index of the utunN device.

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.
