Josh Bleecher Snyder	758c37b83d	net/netns: thread logf into control functions So that darwin can log there without panicking during tests. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	85184a58ed	wgengine/wgcfg: recover from mismatched PublicKey/Endpoints In rare circumstances (tailscale/corp#3016), the PublicKey and Endpoints can diverge. This by itself doesn't cause any harm, but our early exit in response did, because it prevented us from recovering from it. Remove the early exit.

Brad Fitzpatrick	8ec44d0d5f	wgengine/magicsock: remove some log spam Fixes tailscale/corp#3070 Change-Id: Ie50031800ec8669e0596ad6d59d1e329a5c88516 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

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). Updates #3307 Change-Id: Ide768848d7b7d0591e558f118b553013d1ec94ad Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	7901289578	wgengine/magicsock: add a stress test And add a peerMap validate method that checks its internal invariants. Updates tailscale/corp#3016 Change-Id: I23708e68ed44d81986d9e2be82029d4555547592 Co-authored-by: Brad Fitzpatrick <bradfitz@tailscale.com> Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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. Updates #654 Fixes #3247 (I hope) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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

David Anderson	41da7620af	go.mod: update wireguard-go to pick up roaming toggle wgengine/wgcfg: introduce wgcfg.NewDevice helper to disable roaming at all call sites (one real plus several tests).

Josh Bleecher Snyder	c467ed0b62	wgengine/wgcfg: always close io.Pipe In DeviceConfig, we did not close r after calling FromUAPI. If FromUAPI returned early due to an error, then it might not have read all the data that IpcGetOperation wanted to write. As a result, IpcGetOperation could hang, as in #3220. We were also closing the wrong end of the pipe after IpcSetOperation in ReconfigDevice. To ensure that we get all available information to diagnose such a situation, include all errors anytime something goes wrong. This should fix the immediate crashing problem in #3220. We'll then need to figure out why IpcGetOperation was failing. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package github.com/go-multierror/multierror served us well. But we need a few feature from it (implement Is), and it's not worth maintaining a fork of such a small module. Instead, I did a clean room implementation inspired by its API.

Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run.
