David Crawshaw	92e9a5ac15	tailscaled.service: use default restart limiting It appears that systemd has sensible defaults for limiting crash loops: DefaultStartLimitIntervalSec=10s DefaultStartLimitBurst=5 Remove our insta-restart configuration so that it works.

Brad Fitzpatrick	ff8c8db9d3	cmd/tailscaled: log on shutdown signal	4 years ago
Brad Fitzpatrick	2072dcc127	version: revert the filepath change from earlier commit `f81233524f` changed a use of package 'path' to 'filepath'. Restore it back to 'path', with a comment. Also, use the os.Executable-based fallback name in the case where the binary itself doesn't have Go module information. That was overlooked in the original code.	4 years ago
Brad Fitzpatrick	6013462e9e	logpolicy: remove inaccurate comment, conditional tryFixLogStateLocation call What I was probably actually hitting was exe caching issues where the binary was updated on a SMB shared drive and I tried to run it with the GUI exe still open, so Windows blends the two pages together and causes all sorts of random corruption. I didn't know about that at the time. Now, just call tryFixLogStateLocation unconditionally. The func itself will bail out early on non-applicable OSes. (And rearrange it to return even a bit earlier.)	4 years ago
Avery Pennarun	60c00605d3	ipn/setClientStatus: fix inverted prefsChanged check. We need to emit Prefs when it has changed, not when it hasn't. Test is added in our e2e test, separately. Fixes: #620 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	f81233524f	version/cmdname: s/path/filepath/ and fix version.ReadExe() fallback. We were using the Go 'path' module, which apparently doesn't handle backslashes correctly. path/filepath does. However, the main bug turned out to be that we were not calling .Base() on the path if version.ReadExe() fails, which it seems to do at least on Windows 7. As a result, our logfile persistence was not working on Windows, and logids would be regenerated on every restart. Affects: #620 Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago

Brad Fitzpatrick	cbf71d5eba	ipn/ipnserver: fix bug in earlier commit where conn can be stranded If a connection causes getEngine to transition from broken to fixed, that connection was getting lost.	4 years ago

Brad Fitzpatrick	9ff5b380cb	ipn/ipnserver: staticcheck is not wrong shamecube.gif	4 years ago
Brad Fitzpatrick	4aba86cc03	ipn/ipnserver: make Engine argument a func that tries again for each connection So a backend in server-an-error state (as used by Windows) can try to create a new Engine again each time somebody re-connects, relaunching the GUI app. (The proper fix is actually fixing Windows issues, but this makes things better in the short term) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d55fdd4669	wgengine/magicsock: update, flesh out a TODO	4 years ago
Brad Fitzpatrick	d96d26c22a	wgengine/filter: don't spam logs on dropped outgoing IPv6 ICMP or IPv4 IGMP The OS (tries) to send these but we drop them. No need to worry the user with spam that we're dropping it. Fixes #402 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	58b721f374	wgengine/magicsock: deflake some tests with an ugly hack Starting with `fe68841dc7`, some e2e tests got flaky. Rather than debug them (they're gnarly), just revert to the old behavior as far as those tests are concerned. The tests were somehow using magicsock without a private key and expecting it to do ... something. My goal with `fe68841dc7` was to stop log spam and unnecessary work I saw on the iOS app when when stopping the app. Instead, only stop doing that work on any transition from once-had-a-private-key to no-longer-have-a-private-key. That fixes what I wanted to fix while still making the mysterious e2e tests happy.	4 years ago
Brad Fitzpatrick	ec4feaf31c	cmd/cloner, tailcfg: fix nil vs len 0 issues, add tests, use for Hostinfo Also use go:generate and https://golang.org/s/generatedcode header style. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

David Anderson	0249236cc0	ipn/ipnstate: record assigned Tailscale IPs. wgengine/magicsock: use ipnstate to find assigned Tailscale IPs. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	c3958898f1	tstest/natlab: be a bit more lenient during test shutdown. There is a race in natlab where we might start shutdown while natlab is still running a goroutine or two to deliver packets. This adds a small grace period to try and receive it before continuing shutdown. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	7578c815be	wgengine/magicsock: give pinger a more generous packet timeout. The first packet to transit may take several seconds to do so, because setup rates in wgengine may result in the initial WireGuard handshake init to get dropped. So, we have to wait at least long enough for a retransmit to correct the fault. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	c3994fd77c	derp: remove OnlyDisco option. Active discovery lets us introspect the state of the network stack precisely enough that it's unnecessary, and dropping the initial DERP packets greatly slows down tests. Additionally, it's unrealistic since our production network will never deliver _only_ discovery packets, it'll be all or nothing. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5455c64f1d	wgengine/magicsock: add a test for two facing endpoint-independent NATs. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	f794493b4f	wgengine/magicsock: explicitly check path discovery, add a firewall test. The test proves that active discovery can traverse two facing firewalls. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	f582eeabd1	wgengine/magicsock: add a test for active path discovery. Uses natlab only, because the point of this active discovery test is going to be that it should get through a lot of obstacles. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	a2b4ad839b	net/netcheck: lower the hairpin check timeout to 100ms. This single check is the long pole for netcheck, and significantly slows down magicsock tests. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	25288567ec	net/netcheck: centralize all clock values in one place. This makes it easier to see how long a netcheck might take, and what the slow bits might be. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	5a370d545a	tstest/natlab: drop packets that can't be routed in a LAN. LANs are authoritative for their prefixes, so we should not bounce packets back and forth to the default gateway in that case. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	37903a9056	wgengine/magicsock: fix occasional deadlock on Conn.Close on c.derpStarted The deadlock was: * Conn.Close was called, which acquired c.mu * Then this goroutine scheduled: if firstDerp { startGate = c.derpStarted go func() { dc.Connect(ctx) close(c.derpStarted) }() } * The getRegion hook for that derphttp.Client then ran, which also tries to acquire c.mu. This change makes that hook first see if we're already in a closing state and then it can pretend that region doesn't exist.	4 years ago
