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
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 To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

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

Martin Baillie	8ae3ba0cf5	wgengine: define default tunname for each platform The device name "tailscale0" will be used for all platforms except for OpenBSD where "tun" is enforced by the kernel. `CreateTUN()` in `wireguard-go` will select the next available "tunX" device name on the OpenBSD system.

David Anderson	15b4d26d92	logpolicy: automatically figure out paths and filenames. The autoselection should pick sensible paths for all of: - Windows (LocalAppData) - Mac (Library/Caches) - Unix user (XDG_CACHE_DIR) - Linux systemd service (CACHE_DIRECTORY) As a last resort, if cache dir lookup fails, plops sufficiently uniquely named files into the current working directory.

David Anderson	4460bd638b	safesocket: simplify API. On unix, we want to provide a full path to the desired unix socket. On windows, currently we want to provide a TCP port, but someday we'll also provide a "path-ish" object for a named pipe. For now, simplify the API down to exactly a path and a TCP port.

David Anderson	62fb652eef	cmd/tailscaled: run off internal state autonomously. With this change, tailscaled can be restarted and reconnect without interaction from `tailscale`, and `tailscale` is merely there to provide login assistance and adjust preferences.

Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
