Hi,
Funny things are happening with my /proc filesystem under patchlevel 6.
As root, I did:
Nyongwa> ls -l /proc
total 0
dr-xr-xr-x 4 root system 0 Dec 9 18:19 1/
[ ... ]
dr-xr-xr-x 4 rpelleri bbsuser 0 Dec 9 18:19 38056/
Seems good to me. Then I do:
Nyongwa> ls -l /proc/38056
ls: /proc/38056/mem: No such file or directory
ls: /proc/38056/cwd: No such file or directory
ls: /proc/38056/root: No such file or directory
ls: /proc/38056/exe: No such file or directory
ls: /proc/38056/fd: No such file or directory
ls: /proc/38056/lib: No such file or directory
ls: /proc/38056/environ: No such file or directory
ls: /proc/38056/cmdline: No such file or directory
ls: /proc/38056/stat: No such file or directory
total 0
Surely anyone should be able to read this directory? Especially root?
All the processes owned by root are readable by everyone; but any other
userid's processes are unreadable by anyone but the owner.
