Josh Bleecher Snyder	98cae48e70	wgengine/wglog: optimize wireguardGoString The new code is ugly, but much faster and leaner. name old time/op new time/op delta SetPeers-8 7.81µs ± 1% 3.59µs ± 1% -54.04% (p=0.000 n=9+10) name old alloc/op new alloc/op delta SetPeers-8 7.68kB ± 0% 2.53kB ± 0% -67.08% (p=0.000 n=10+10) name old allocs/op new allocs/op delta SetPeers-8 237 ± 0% 99 ± 0% -58.23% (p=0.000 n=10+10) Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	59026a291d	wgengine/wglog: improve wireguard-go logging rate limiting Prior to wireguard-go using printf-style logging, all wireguard-go logging occurred using format string "%s". We fixed that but continued to use %s when we rewrote peer identifiers into Tailscale style. This commit removes that %sl, which makes rate limiting work correctly. As a happy side-benefit, it should generate less garbage. Instead of replacing all wireguard-go peer identifiers that might occur anywhere in a fully formatted log string, assume that they only come from args. Check all args for things that look like *device.Peers and replace them with appropriately reformatted strings. There is a variety of ways that this could go wrong (unusual format verbs or modifiers, peer identifiers occurring as part of a larger printed object, future API changes), but none of them occur now, are likely to be added, or would be hard to work around if they did.

Josh Bleecher Snyder	1f94d43b50	wgengine/wglog: delay formatting The "stop phrases" we use all occur in wireguard-go in the format string. We can avoid doing a bunch of fmt.Sprintf work when they appear. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	3 years ago
Josh Bleecher Snyder	7ee891f5fd	all: delete wgcfg.Key and wgcfg.PrivateKey For historical reasons, we ended up with two near-duplicate copies of curve25519 key types, one in the wireguard-go module (wgcfg) and one in the tailscale module (types/wgkey). Then we moved wgcfg to the tailscale module. We can now remove the wgcfg key type in favor of wgkey. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	3 years ago
Josh Bleecher Snyder	a29b0cf55f	wgengine/wglog: allow wireguard-go receive routines to log I've spent two days searching for a theoretical wireguard-go bug around receive functions exiting early. I've found many bugs, but none of the flavor we're looking for. Restore wireguard-go's logging around starting and stopping receive functions, so that we can definitively rule in or out this particular theory.

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>	3 years ago
Josh Bleecher Snyder	d5baeeed5c	wgengine: use Tailscale-style peer identifiers in logs Rewrite log lines on the fly, based on the set of known peers. This enables us to use upstream wireguard-go logging, but maintain the Tailscale-style peer public key identifiers that the rest of our systems (and people) expect. Fixes #1183 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
