Subject: [PATCH] [release-branch.go1.16] syscall: fix ForkLock spurious
close(0) on pipe failure
Pipe (and therefore forkLockPipe) does not make any guarantees
about the state of p after a failed Pipe(p). Avoid that assumption
and the too-clever goto, so that we don't accidentally Close a real fd
if the failed pipe leaves p[0] or p[1] set >= 0.
Updates #50057
Fixes CVE-2021-44717
