Brad Fitzpatrick	abd79ea368	derp: reduce DERP memory use; don't require callers to pass in memory to use The magicsock derpReader was holding onto 65KB for each DERP connection forever, just in case. Make the derp{,http}.Client be in charge of memory instead. It can reuse its bufio.Reader buffer space.	5 years ago

Brad Fitzpatrick	484b7fc9a3	derp, cmd/derper: add frameWatchConns, framePeerPresent for inter-DERP routing This lets a trusted DERP client that knows a pre-shared key subscribe to the connection list. Upon subscribing, they get the current set of connected public keys, and then all changes over time. This lets a set of DERP server peers within a region all stay connected to each other and know which clients are connected to which nodes.

David Anderson	c62b80e00b	cmd/tailscale: fix inverted flag meanings. The flags were --no-blah for a brief time, then we switched them to --blah=true/false with a default of true, but didn't fix the boolean inversions in the code. So up was down, true was false, etc. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago

Brad Fitzpatrick	984a699219	cmd/tailscale: warn to stderr that netcheck -format=json isn't stable	5 years ago
Brad Fitzpatrick	0245bbe97b	Make netcheck handle v6-only interfaces better, faster. Also: * add -verbose flag to cmd/tailscale netcheck * remove some API from the interfaces package * convert some of the interfaces package to netaddr.IP * don't even send IPv4 probes on machines with no IPv4 (or only v4 loopback) * and once three regions have replied, stop waiting for other probes at 2x the slowest duration. Updates #376	5 years ago
Brad Fitzpatrick	a96165679c	cmd/tailscale: add netcheck flags for incremental reports, JSON output	5 years ago
Avery Pennarun	9ff51909a3	router_linux: fix behaviour when switching --netfilter-mode. On startup, and when switching into =off and =nodivert, we were deleting netfilter rules even if we weren't the ones that added them. In order to avoid interfering with rules added by the sysadmin, we have to be sure to delete rules only in the case that we added them in the first place.

Avery Pennarun	85d93fc4e3	cmd/tailscale: make ip_forward warnings more actionable. Let's actually list the file we checked (/proc/sys/net/ipv4/ip_forward). That gives the admin something specific to look for when they get this message. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	99aa33469e	cmd/tailscale: be quiet when no interaction or errors are needed. We would print a message about "nothing more to do", which some people thought was an error or warning. Let's only print a message after authenticating if we previously asked for interaction, and let's shorten that message to just "Success," which is what it means.

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

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.

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

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.
