I did some more inspection, and I don't think this assumption is correct. It looks like the first ERROR case is handled The ENOTCAPABLE part is definitely an issue. CAP_PREAD needs to be set on `fd` and CAP_SEND needs to be set on `s`. I submitted a pull request for the ENOTCAPABLE documentation item: https://github.com/freebsd/freebsd/pull/170 . -- You are receiving this mail because: You are the assignee for the bug.help
