Tom DNetto	8602061f32	ipn/ipnlocal,tka: Fix bugs found by integration testing * tka.State.staticValidateCheckpoint could call methods on a contained key prior to calling StaticValidate on that key * Remove broken backoff / RPC retry logic from tka methods in ipn/ipnlocal, to be fixed at a later time * Fix NetworkLockModify() which would attempt to take b.mu twice and deadlock, remove now-unused dependence on netmap * Add methods on ipnlocal.LocalBackend to be used in integration tests * Use TAILSCALE_USE_WIP_CODE as the feature flag so it can be manipulated in tests Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Mihai Parparita	7ffd2fe005	cmd/tsconnect: switch to non-beta versions of xterm and related packages xterm 5.0 was released a few weeks ago, and it picks up xtermjs/xterm.js#4069, which was the main reason why we were on a 5.0 beta. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Joe Tsai	2934c5114c	net/tunstats: new package to track per-connection counters (#5818 ) High-level API: type Statistics struct { ... } type Counts struct { TxPackets, TxBytes, RxPackets, RxBytes uint64 } func (Statistics) UpdateTx([]byte) func (Statistics) UpdateRx([]byte) func (*Statistics) Extract() map[flowtrack.Tuple]Counts The API accepts a []byte instead of a packet.Parsed so that a future implementation can directly hash the address and port bytes, which are contiguous in most IP packets. This will be useful for a custom concurrent-safe hashmap implementation. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
David Anderson	bdf3d2a63f	cmd/pgproxy: open-source our postgres TLS-enforcing proxy. From the original commit that implemented it: It accepts Postgres connections over Tailscale only, dials out to the configured upstream database with TLS (using strong settings, not the swiss cheese that postgres defaults to), and proxies the client through. It also keeps an audit log of the sessions it passed through, along with the Tailscale-provided machine and user identity of the connecting client. In our other repo, this was: commit 92e5edf98e8c2be362f564a408939a5fc3f8c539, Change-Id I742959faaa9c7c302bc312c7dc0d3327e677dc28.

Brad Fitzpatrick	bb7be74756	net/dns/publicdns: permit more NextDNS profile bits in its IPv6 suffix I brain-o'ed the math earlier. The NextDNS prefix is /32 (actually /33, but will guarantee last bit is 0), so we have 128-32 = 96 bits (12 bytes) of config/profile ID that we can extract. NextDNS doesn't currently use all those, but might. Updates #2452 Change-Id: I249bd28500c781e45425fd00fd3f46893ae226a2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

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

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	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
Mihai Parparita	c66e15772f	tsweb: consider 304s as successful for quiet logging Static resource handlers will generate lots of 304s, which are effectively successful responses. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
