Josh Bleecher Snyder	2d837f79dc	wgengine/magicsock: close test loggers once we're done with them This is a big hammer approach to helping with #1132. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
David Anderson	22507adf54	wgengine/magicsock: stop depending on UpdateDst in legacy codepaths. This makes connectivity between ancient and new tailscale nodes slightly worse in some cases, but only in cases where the ancient version would likely have failed to get connectivity anyway.

Smitty	2bf49ddf90	Provide example when format string is rate limited Here's an example log line in the new format: [RATE LIMITED] format string "open-conn-track: timeout opening %v; no associated peer node" (example: "open-conn-track: timeout opening ([ip] => [ip]); no associated peer node") This should make debugging logging issues a bit easier, and give more context as to why something was rate limited. This change was proposed in a comment on #1110. Signed-off-by: Smitty <me@smitop.com>	4 years ago
Josh Bleecher Snyder	1e4604f60e	wgengine: quiet some wireguard-go logging The log lines that wireguard-go prints as it starts and stops its worker routines are mostly noise. They also happen after other work is completed, which causes failures in some of the log testing packages. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	56a7652dc9	wgkey: new package This is a replacement for the key-related parts of the wireguard-go wgcfg package. This is almost a straight copy/paste from the wgcfg package. I have slightly changed some of the exported functions and types to avoid stutter, added and tweaked some comments, and removed some now-unused code. To avoid having wireguard-go depend on this new package, wgcfg will keep its key types. We translate into and out of those types at the last minute. These few remaining uses will be eliminated alongside the rest of the wgcfg package. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Smitty	f0b0a62873	Clarify that raw format strings are intentional This caused some confusion in issue #460, since usually raw format strings aren't printed directly. Hopefully by directly logging that they are intended to be raw format strings, this will be more clear. Rate limited format strings now look like: [RATE LIMITED] format string "control: sendStatus: %s: %v" Closes #460. Signed-off-by: Smitty <me@smitop.com>	4 years ago
Brad Fitzpatrick	19b0cfe89e	all: prepare for GOOS=ios in Go 1.16 Work with either way for now on iOS (darwin/arm64 vs ios/arm64). In February when Go 1.16 comes out we'll have a universal binary for darwin/arm64 (macOS) and will drop support for Go 1.15 and its darwin/amd64 meaning iOS. (it'll mean macOS).

Brad Fitzpatrick	8b904b1493	types/logger: fix LogOnChange to pass through format/args to underlying logger So they don't get interpretted as a format pattern or get rate-limited away in the wrong way.	4 years ago
Brad Fitzpatrick	691f1d5c1d	types/flagtype: fix bug showing the default port value (shown in --help)	4 years ago
Brad Fitzpatrick	86c271caba	types/logger: move RusagePrefixLog to logger package, disable by default The RusagePrefixLog is rarely useful, hasn't been useful in a long time, is rarely the measurement we need, and is pretty spammy (and syscall-heavy). Disable it by default. We can enable it when we're debugging memory.	4 years ago
Brad Fitzpatrick	8b94a769be	cmd/tailscaled: use the standard flag page instead of getopt Per discussion with @crawshaw. The CLI tool already used std flag anyway. If either of them, it would've made more sense for the CLI to use getopt.	4 years ago
Brad Fitzpatrick	309c15dfdd	types/key: restore Curve25519 clamping in NewPrivate It was lost during a copy from wgcfg.NewPresharedKey (which doesn't clamp) instead of wgcfg.NewPrivateKey (which does). Fortunately this was only use for discovery messages (not WireGuard) and only for ephemeral process-lifetime keys.	4 years ago
Elias Naur	fa45d606fa	types/logger: fix go test vet error Silences types/logger/logger_test.go:63:30: conversion from int to string yields a string of one rune Signed-off-by: Elias Naur <mail@eliasnaur.com>	4 years ago
Brad Fitzpatrick	6c74065053	wgengine/magicsock, tstest/natlab: start hooking up natlab to magicsock Also adds ephemeral port support to natlab. Work in progress. Pairing with @danderson.	4 years ago

Brad Fitzpatrick	3f4a567032	types/strbuilder: add a variant of strings.Builder that uses sync.Pool ... and thus does not need to worry about when it escapes into unprovable fmt interface{} land. Also, add some convenience methods for efficiently writing integers.	4 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.

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.

Brad Fitzpatrick	fefd7e10dc	types/structs: add structs.Incomparable annotation, use it where applicable Shotizam before and output queries: sqlite> select sum(size) from bin where func like 'type..%'; 129067 => 120216	5 years ago
Brad Fitzpatrick	45f2b53aca	all: remove unnecessary trailing newlines in format patterns for consistency And document on logger.Logf that it's unnecessary.	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
