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
Josh Bleecher Snyder	94fb42d4b2	all: use testingutil.MinAllocsPerRun There are a few remaining uses of testing.AllocsPerRun: Two in which we only log the number of allocations, and one in which dynamically calculate the allocations target based on a different AllocsPerRun run. This also allows us to tighten the "no allocs" test in wgengine/filter. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	5 years ago
