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>
2022-08-28util/cstruct: add package for decoding padded C structures (#5429)Andrew Dunham1-0/+151
I was working on my "dump iptables rules using only syscalls" branch and had a bunch of C structure decoding to do. Rather than manually calculating the padding or using unsafe trickery to actually cast variable-length structures to Go types, I'd rather use a helper package that deals with padding for me. Padding rules were taken from the following article: http://www.catb.org/esr/structure-packing/ Signed-off-by: Andrew Dunham <andrew@du.nham.ca>
