Brad Fitzpatrick	c0cdca6d06	cmd/tailscaled, logtail: share link monitor from wgengine to logtail ... Part of overall effort to clean up, unify, use link monitoring more, and make Tailscale quieter when all networks are down. This is especially bad on macOS where we can get killed for not being polite it seems. (But we should be polite in any case) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor ... Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it. This also removes the Engine.LinkChange method, as it's no longer necessary. The monitor tells us about changes; it doesn't seem to need any help. (Currently it was only used by Swift, but as of 14dc790137 we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	dda03a911e	wgengine/monitor: change API to permit multiple independent callbakcks ... Currently it assumes exactly 1 registered callback. This changes it to support 0, 1, or more than 1.

Brad Fitzpatrick	ddfcc4326c	types/persist: split controlclient.Persist into a small leaf package ... This one alone doesn't modify the global dependency map much (depaware.txt if anything looks slightly worse), but it leave controlclient as only containing NetworkMap: bradfitz@tsdev:~/src/tailscale.com/ipn$ grep -F "controlclient." *.go backend.go: NetMap *controlclient.NetworkMap // new netmap received fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) fake_test.go: b.notify(Notify{NetMap: &controlclient.NetworkMap{}}) handle.go: netmapCache *controlclient.NetworkMap handle.go:func (h *Handle) NetMap() *controlclient.NetworkMap { Once that goes into a leaf package, then ipn doesn't depend on controlclient at all, and then the client gets smaller.

Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go ... This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Brad Fitzpatrick	5efb0a8bca	cmd/tailscale: change formatting of "tailscale status" ... * show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns	4 years ago

Frederik “Freso” S. Olesen	83fccf9fe5	tailscaled.service: Lock down clock and /dev (#1071) ... Research in issue #1063 uncovered why tailscaled would fail with ProtectClock enabled (it implicitly enabled DevicePolicy=closed). This knowledge in turn also opens the door for locking down /dev further, e.g. explicitly setting DevicePolicy=strict (instead of closed), and making /dev private for the unit. Additional possible future (or downstream) lockdown that can be done is setting `PrivateDevices=true` (with `BindPaths=/dev/net/`), however, systemd 233 or later is required for this, and tailscaled currently need to work for systemd down to version 215.

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
Frederik “Freso” S. Olesen	a9a80ab372	tailscaled.service: Harden systemd unit somewhat (#1062) ...

Brad Fitzpatrick	57dd247376	cmd/tailscaled, logpolicy, logtail: support log levels ... Log levels can now be specified with "[v1] " or "[v2] " substrings that are then stripped and filtered at the final logger. This follows our existing "[unexpected]" etc convention and doesn't require a wholesale reworking of our logging at the moment. cmd/tailscaled then gets a new --verbose=N flag to take a log level that controls what gets logged to stderr (and thus systemd, syslog, etc). Logtail is unaffected by --verbose. This commit doesn't add annotations to any existing log prints. That is in the next commit.

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	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.
