Fix this by handling the CLOSE_RANGE_CLOEXEC case and # copying all fds if the two flags are specified together. # # This should've been caught in the selftests but the original patch # didn't cover this case and I didn't catch it during review. So in # addition to the bugfix I'm also adding selftests. They will reliably # reproduce the bug on a non-fixed kernel and allows us to catch # regressions and verify correct behavior. # # Note, the kernel selftest tree contained a bunch of changes that made # the original selftest fail to compile so there are small fixups in # here make them compile without warnings" # # * tag 'close-range-cloexec-unshare-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: #
