Why doesn't setfsuid return -EPERM when it can't perform the operation?
file: kernel/sys.c, 'sys_setfsuid' around line 779 depending on your
source version.
There is a check if capable(CAP_SETUID), that if it fails, doesn't
return an error. This seems inconsistent. In fact the manpage
I have on it states:
RETURN VALUE
On success, the previous value of fsuid is returned. On
error, the current value of fsuid is returned.
BUGS
No error messages of any kind are returned to the caller.
At the very least, EPERM should be returned when the call
fails.
