This seems to be correct I was able to get the check to pass if I hardcode the st->st_uid in S_io_stat in pflocal.io.c. The problem is that /hurd/pflocal is owned by and in the group root, so when I call getuid() or geteuid() it returns 0 (the uid for root). I tried setting the SETUID bit of the file itself with sudo chmod +s /hurd/local but this had no impact on either result from what I could see. I'm at an impasse, then, because I can't find a way to get the uid of the user that actually requested the port to put in st_uid. Any suggestions? Andrew
