Dmitry Adamushko	806645ea0e	derp: prevent readFrame() from reading more than len(b) bytes. Signed-off-by: Dmitry Adamushko <da@stablebits.net>	5 years ago
Dmitry Adamushko	f2c2d0de68	derp/derp_server: unregisterClient() for replaced client connections. When unregistering a replaced client connection, move the still-connected peers to the current client connecition. Inform the peers that we've gone only when unregistering the active client connection. Signed-off-by: Dmitry Adamushko <da@stablebits.net>	5 years ago

David Crawshaw	5b95aa81ea	wgengine: remove IpcSetOperation on LinkChange This was only done occasionally, but was extremely disruptive when done and is no longer necessary. It used to be that when switching links, we had to immediately generate handshakes to everyone we were communicating with to punch a hole in any NAT we were talking through. (This ended up not really working, because in the process we got rid of our session keys and ended up having a futile conversation for many seconds.) Now we have DERP, our link change propogates to the other side as a new list of endpoints, so they start spraying packets. We will definitely get one thanks to DERP, which will cause us to spray, opening any NAT we are behind. The result is that for good connections, we don't trash session keys and cause an interruption.

Brad Fitzpatrick	73249f8032	netcheck: aggregate spammy logging onto one concise line	5 years ago
Brad Fitzpatrick	922d9546bf	wgengine: don't allocate so much in userspaceEngine.getStatus It was one of the top garbage producers on my phone. It's slated to be deleted and replaced anyway, but this helps in the meantime. The go.sum changes look scary, but the new dep only adds 240 bytes to the binary. The go.sum noise is just cmd/go being aggressive in including a lot of stuff (which is being fixed in Go 1.15, for what I understand). And I ran a go mod tidy, which added some too. (I had to write a custom wrapper around go mod tidy because this mod tidy normally breaks on tailscale.io/control being missing but referenced in tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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

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	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	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").

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.
