2023-06-23util/goroutines: let ScrubbedGoroutineDump get only current stackBrad Fitzpatrick1-1/+1
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. Updates tailscale/corp#5149 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
2023-01-27all: update copyright and license headersWill Norris1-3/+2
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>
