Anton Tolchanov	100d8e909e	cmd/derpprobe: migrate to the prober framework ... `prober.DERP` was created in #5988 based on derpprobe. Having used it instead of derpprobe for a few months, I think we have enough confidence that it works and can now migrate derpprobe to use the prober framework and get rid of code duplication. A few notable changes in behaviour: - results of STUN probes over IPv4 and IPv6 are now reported separately; - TLS probing now includes OCSP verification; - probe names in the output have changed; - ability to send Slack notification from the prober has been removed. Instead, the prober now exports metrics in Expvar (/debug/vars) and Prometheus (/debug/varz) formats.

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>	3 years ago
Anton Tolchanov	69f61dcad8	prober: add a DERP probe manager based on derpprobe ... This ensures that each DERP server is probed individually (TLS and STUN) and also manages per-region mesh probing. Actual probing code has been copied from cmd/derpprobe. Signed-off-by: Anton Tolchanov <anton@tailscale.com>	4 years ago
