We previous added code for passing FDs which was explicitly derived from gnulib's passfd code: commit 17460825f3c78e1635f2beb0165c5a19e3b09f7d Author: Daniel P. Berrangé <berrange(a)redhat.com&gt; Date: Fri Jan 17 11:57:17 2020 +0000 src: implement APIs for passing FDs over UNIX sockets This is a simplified variant of gnulib's passfd module without the portability code that we do not require. while the license was unchanged, we mistakenly failed to copy the FSF copyright header which is required by the license terms.
