Brad Fitzpatrick	49a3fcae78	log/filelogger: make filelogger remove redundant date before adding a date At some point since filelogger was added on Windows, the log hierarchy above it changed such that a log.Printf writes to filelogger and includes the log package's own date. But then filelogger adds another. Rather than debug everything above and risk removing the prefix when run by tailscaled, instead just remove the log package's prefix very late right before we go to add the filelogger's own.

Brad Fitzpatrick	d24ed3f68e	wgengine/router: add debug knob to resort to Linux "ip" command usage Tailscale 1.18 uses netlink instead of the "ip" command to program the Linux kernel. The old way was kept primarily for tests, but this also adds a TS_DEBUG_USE_IP_COMMAND environment knob to force the old way temporarily for debugging anybody who might have problems with the new way in 1.18. Updates #391 Change-Id: I0236fbfda6c9c05dcb3554fcc27ec0c86456efd9 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	b3d6704aa3	wgengine/magicsock: fix data race on endpoint.discoKey endpoint.discoKey is protected by endpoint.mu. endpoint.sendDiscoMessage was reading it without holding the lock. This showed up in a CI failure and is readily reproducible locally. The fix is in two parts. First, for Conn.enqueueCallMeMaybe, eliminate the one-line helper method endpoint.sendDiscoMessage; call Conn.sendDiscoMessage directly. This makes it more natural to read endpoint.discoKey in a context in which endpoint.mu is already held. Second, for endpoint.sendDiscoPing, explicitly pass the disco key as an argument. Again, this makes it easier to read endpoint.discoKey in a context in which endpoint.mu is already held. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Brad Fitzpatrick	cf06f9df37	net/tstun, wgengine: add packet-level and drop metrics Primarily tstun work, but some MagicDNS stuff spread into wgengine. No wireguard reconfig metrics (yet).

Josh Bleecher Snyder	5a60781919	wgengine/magicsock: increase TestDiscokeyChange connection timeout I believe that this should eliminate the flakiness. If GitHub CI manages to be even slower that can be believed (and I can believe a lot at this point), then we should roll this back and make some more invasive changes.

Josh Bleecher Snyder	773af7292b	wgengine/magicsock: simplify peerMap.upsertEndpoint We can do the "maybe delete" check unilaterally: In the case of an insert, both oldDiscoKey and ep.discoKey will be the zero value. And since we don't use pi again, we can skip giving it a name, which makes scoping clearer. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	e6fbc0cd54	cmd/tailscaled, ipn/ipnserver: refactor ipnserver More work towards removing the massive ipnserver.Run and ipnserver.Options and making composable pieces. Work remains. (The getEngine retry loop on Windows complicates things.) For now some duplicate code exists. Once the Windows side is fixed to either not need the retry loop or to move the retry loop into a custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go too.
