It is not broken for me here so there is something funny on your side.
Try this sequence of things:
cat /selinux/enforce
alias w
alias ls
which w
ls -l `which w`
id
strace -o /tmp/trace-w /usr/bin/w
Now look at the various file access system calls made
by "w" in the trace file
egrep "stat|open" /tmp/trace-w | less
Also inspect /var/log/messages and see if there is a clue there.
Stuff like this is 'normal' in the trace file.
....
open("/proc/25191/stat", O_RDONLY) = 4
open("/proc/25191/cmdline", O_RDONLY) = 4
open("/etc/localtime", O_RDONLY) = 3
open("/proc/uptime", O_RDONLY) = 3
open("/var/run/utmp", O_RDWR) = -1 EACCES (Permission denied)
open("/var/run/utmp", O_RDONLY) = 4
open("/proc/loadavg", O_RDONLY) = 4
open("/var/run/utmp", O_RDWR) = -1 EACCES (Permission denied)
open("/var/run/utmp", O_RDONLY) = 5
....
And just in case you do not have strace loaded. You can
check for it.
$ rpm -q --whatprovides `which strace`
strace-4.5.5-1
