Tom DNetto	ab591906c8	wgengine/router: Increase range of rule priorities when detecting mwan3 Context: https://github.com/tailscale/tailscale/pull/5588#issuecomment-1260655929 It seems that if the interface at index 1 is down, the rule is not installed. As such, we increase the range we detect up to 2004 in the hope that at least one of the interfaces 1-4 will be up. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago
Mihai Parparita	9214b293e3	tstime: add ParseDuration helper function More expressive than time.ParseDuration, also accepting d (days) and w (weeks) literals. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Aaron Klotz	44f13d32d7	cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.

Brad Fitzpatrick	8a0cb4ef20	control/controlclient: fix recent set-dns regression SetDNS calls were broken by `6d04184325` the other day. Unreleased. Caught by tests in another repo. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	fb4e23506f	control/controlclient: stop restarting map polls on health change At some point we started restarting map polls on health change, but we don't remember why. Maybe it was a desperate workaround for something. I'm not sure it ever worked. Rather than have a haunted graveyard, remove it. In its place, though, and somewhat as a safety backup, send those updates over the HTTP/2 noise channel if we have one open. Then if there was a reason that a map poll restart would help we could do it server-side. But mostly we can gather error stats and show machine-level health info for debugging.

Brad Fitzpatrick	6d04184325	control/controlclient: add a noiseClient.post helper method In prep for a future change that would've been very copy/paste-y.

James Tucker	146f51ce76	net/packet: fix filtering of short IPv4 fragments The fragment offset is an 8 byte offset rather than a byte offset, so the short packet limit is now in fragment block size in order to compare with the offset value. The packet flags are in the first 3 bits of the flags/frags byte, and so after conversion to a uint16 little endian value they are at the start, not the end of the value - the mask for extracting "more fragments" is adjusted to match this byte. Extremely short fragments less than 80 bytes are dropped, but fragments over 80 bytes are now accepted. Fixes #5727 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago

Brad Fitzpatrick	2c447de6cc	cmd/tailscaled: use explicit equal sign in --port=$PORT in tailscaled.service Personal preference (so it's obvious it's not a bool flag), but it also matches the --state= before it. Bonus: stop allowing PORT to sneak in extra flags to be passed as their own arguments, as $FOO and ${FOO} expand differently.

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.
