Brad Fitzpatrick	7c1068b7ac	util/goroutines: let ScrubbedGoroutineDump get only current stack ScrubbedGoroutineDump previously only returned the stacks of all goroutines. I also want to be able to use this for only the current goroutine's stack. Add a bool param to support both ways.

Mihai Parparita	d0906cda97	net/sockstats: expose debug info Exposes some internal state of the sockstats package via the C2N and PeerAPI endpoints, so that it can be used for debugging. For now this includes the estimated radio on percentage and a second-by-second view of the times the radio was active. Also fixes another off-by-one error in the radio on percentage that was leading to >100% values (if n seconds have passed since we started to monitor, there may be n + 1 possible seconds where the radio could have been on).

Mihai Parparita	cef0a474f8	ipn/ipnlocal: check that sockstatLogger is available in c2n endpoint Otherwise there may be a panic if it's nil (and the control side of the c2n call will just time out). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Will Norris	f13b8bf0cf	log: use logtail to log and upload sockstat logs Switch to using logtail for logging sockstat logs. Always log locally (on supported platforms), but disable automatic uploading. Change existing c2n sockstats request to trigger upload to log server and return log ID.

David Anderson	8b2ae47c31	version: unexport all vars, turn Short/Long into funcs The other formerly exported values aren't used outside the package, so just unexport them. Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
