Brad Fitzpatrick	0f64d7f9cc	wgengine: remove a tiny allocation Drop in the bucket compared to the larger issues, but noticed it when looking at pprof.	5 years ago
Brad Fitzpatrick	59800138ff	bump wireguard dep	5 years ago
Brad Fitzpatrick	277fe84c6b	version: don't depend on goversion on ios	5 years ago
Brad Fitzpatrick	2776209e49	portlist: don't depend on osexec package on ios, even if it's unused Continuation of `5bb14c07dc`. The earlier commit provided the space savings (as the linker could see through that osexec was unused at runtime), but it didn't clean up the dep graph (from go list -json or godepgraph). This removes the netstat.go file from the build too, just so the dep list looks more reasonable.	5 years ago
Brad Fitzpatrick	5bb14c07dc	portlist: don't depend on tempfork/osexec on iOS, saves 90KB This gives us 90KB more of memory on iOS, as it shrinks the NetworkExtension binary by 90KB. The netstat binary isn't available in the network extension anyway, so no point pulling in the osexec package which'll just fail to find netstat anyway.	5 years ago
Brad Fitzpatrick	ec0cd60fc3	portlist: fail earlier, more nicely on iOS	5 years ago
David Anderson	96b2f20c5b	types/logger: add Discard helper.	5 years ago
Dmitry Adamushko	44434fdc82	derp/derp_server: fixed unbalanced {register,unregister}Client() calls. Signed-off-by: Dmitry Adamushko <da@stablebits.net>	5 years ago
Blake Gentry	e19287f60f	wgengine/magicsock: fix Conn docs type reference The docs on magicsock.Conn stated that they implemented the wireguard/device.Bind interface, yet this type does not exist. In reality, the Conn type implements the wireguard/conn.Bind interface. I also fixed a small typo in the same file. Signed-off-by: Blake Gentry <blakesgentry@gmail.com>	5 years ago
Brad Fitzpatrick	71d6738333	tstime: change an Errorf+return to Fatalf in subtest Forgot to git add this during review. Fail.	5 years ago
Brad Fitzpatrick	febdac0499	tstime: write Parse3339 parse that doesn't use time.Parse It doesn't allocate and it's half the time of time.Parse (which allocates), and 2/3rds the time of time.ParseInLocation (which doesn't).

Brad Fitzpatrick	02948d2c86	Dockerfile: add some usage docs, bump to Go 1.14	5 years ago
Brad Fitzpatrick	d503dee6f1	tstime: add new package for time utilities, starting with Parse3339 Go's time.Parse always allocates a FixedZone for time strings not in UTC (ending in "Z"). This avoids that allocation, at the cost of adding a cache. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	4e0ee141e8	derp/derpmap: add derp5 (Sydney) to prod map. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
Brad Fitzpatrick	996bf9cae7	logtail: don't send a User-Agent Just useless bytes on the wire. Especially with HTTP/1. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	7bf436ba30	tsweb: add some Benchmarks Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	64334143a1	tsweb: rename Handler to ReturnHandler The name's been bugging me for a long time. I liked neither the overlap between tsweb.Handler and http.Handler, nor the name "ServeHTTPErr" which sounds like it's an error being returned, like it's an error handler and not sometimes a happy path.

David Anderson	af3a9dfad6	tsweb: add a StdHandler that doesn't log 200 responses. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago

Brad Fitzpatrick	e71a7c7a2c	logtail: read to EOF on chunked response We'll be fixing the server so this won't trigger in practice, but it demos the connection reuse problem. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago

David Anderson	5d995d9d6b	tsweb: add a test case for nil child errors in tsweb.Error. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	2c2dff9559	tsweb: don't panic if we get a tsweb.Error with no embedded error. It's technically weird to return a tsweb.Error with no child err, but it's a sensible thing to want to do, and we shouldn't panic if it happens. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Crawshaw	2f8719741e	controlclient: do not send duplicate hostinfo/netinfo This should never happen, so log when it does so we can fix it. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Anderson	48d7ee1c6a	cmd/microproxy: adjust to export node stats and a Go expvar server's stats. This is a temporary specialization to what tailscale prod needs right now, it'll go back to something more generic later.	5 years ago
Brad Fitzpatrick	8ca796d144	ipn, ipn/policy: filter portlist to a short list of "interesting" ports Adds new package ipn/policy to be shared between node client & control server. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	c6aa5b639f	tailcfg: clarify Hostinfo.OS doc	5 years ago
Brad Fitzpatrick	4524dcf51e	version: move runtime.OS to tailscale OS mapping func to version So other code can use this without duplicating the policy.	5 years ago

Brad Fitzpatrick	fee2d9fad4	safesocket: connect to the macOS network extension on darwin (as last resort) (For cmd/tailscale CLI support on macOS) Signed-off-by: Brad Fitzpatrick <brad@danga.com>	5 years ago
David Crawshaw	0590ad68be	controlclient, ipn: adjust tests for authURL semantic changes The tests cheat at filling out web forms by directly POSTing to the target. The target for authURLs has changed slightly, the base authURL now redirects the user to the login page. Additionally, the authURL cycle now checks the cookie is set correctly, so we add cookie jars where necessary to pass the cookie through.	5 years ago

David Anderson	dbca186a64	stunner: fix data race. In very low-latency conditions, a STUN request can complete before the startup loop has finished firing off goroutines, leading to a concurrent map mutation.	5 years ago
Brad Fitzpatrick	7fb8d873ac	logpolicy: don't log timestamp when running under systemd It'll do it anyway. Makes journalctl -fu cleaner. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Brad Fitzpatrick	2d48f92a82	wgengine/magicsock: re-stun every [20,27] sec, not 28 28 is cutting it close, and we think jitter will help some spikes we're seeing. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
