Brad Fitzpatrick	b0c10fa610	stun, netcheck: move under net	5 years ago
Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races. Fixes #387 (Don't hard-code the DERP map) Updates #388 (Add DERP region support) Fixes #399 (wgengine: flaky tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages. This greatly reduces the number of messages that are rate limited during startup, but allows us to tighten the limit even further during normal runtime.

Avery Pennarun	f2db4ac277	cmd/tailscaled: SetGCPercent() if GOGC is not set. This cuts RSS from ~30MB to ~20MB on my machine, after the previous fix to get rid of unnecessary zstd buffers. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago

Wendi Yu	bb55694c95	wgengine: log node IDs when peers are added/removed (#381 ) Also stop logging data sent/received from nodes we're not connected to (ie all those `x`s being logged in the `peers: ` line) Signed-off-by: Wendi <wendi.yu@yahoo.ca>	5 years ago

Brad Fitzpatrick	529e2cb31a	ipn: add AllowVersionSkew bool to Notify & Message For "tailscale status" on macOS (from separately downloaded cmd/tailscale binary against App Store IPNExtension). (This isn't all of it, but I've had this sitting around uncommitted.)	5 years ago
Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

Dmytro Shynkevych	68a173bc24	cmd/mkpkg: support adding empty directories. Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	5 years ago
Avery Pennarun	9d1f48032a	cmd/tailscale: add --advertise-tags option. These will be used for dynamically changing the identity of a node, so its ACL rights can be different from your own. Note: Not all implemented yet on the server side, but we need this so we can request the tagged rights in the first place. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Avery Pennarun	d7429b9a8d	Add prefs.ShieldsUp and --shields-up option. This sets a default packet filter that blocks all incoming requests, giving end users more control over who can get into their machine, even if the admin hasn't set any central ACLs.

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	dbfc916273	derp: add short queues between reader and writer, drop on overload. This avoids the server blocking on misbehaving or heavily contended clients. We attempt to drop from the head of the queue to keep overall queueing time lower. Also: - fixes server->client keepalives, which weren't happening. - removes read rate-limiter, deferring instead to kernel-level global limiter/fair queuer.

Avery Pennarun	b4897e7de8	controlclient/netmap: write our own b.ConciseDiffFrom(a) function. This removes the need for go-cmp, which is extremely bloaty so we had to leave it out of iOS. As a result, we had also left it out of macOS, and so we didn't print netmap diffs at all on darwin-based platforms. Oops. As a bonus, the output format of the new function is way better. Minor oddity: because I used the dumbest possible diff algorithm, the sort order is a bit dumb. We print all "removed" lines and then print all "added" lines, rather than doing the usual diff-like thing of interspersing them. This probably doesn't matter (maybe it's an improvement).	5 years ago
