   #TIL Check SO_PEERCRED of a Unix domain socket to find out the client's identity. No need to do hacky challenge-response via the filesystem.

     @niconiconi Interestingly it's not in POSIX

     @niconiconi Strangely manpage-wise it's only in OpenBSD…

     @lanodan@queer.hacktivis.me even NetBSD has this extension, so it's pretty safe to use. It's only missing in macOS but only under a different name LOCAL_PEERCRED.

     @niconiconi And for me the only systems I care about are Linux, BSDs, Haiku and somewhat illumos.
     Even ignoring it being proprietary (and so unfixable software), MacOS is horribly outdated POSIX wise, might as well just consider it formerly/historically UNIX.

     @lanodan@queer.hacktivis.me I misread the manual. In NetBSD it's actually named LOCAL_PEEREID ("You're in a maze of incompatible Unix derivatives, all alike.")

     @niconiconi Which is exactly why POSIX still matters, getting more common ground ^^
