umm
- test basic functionality
- test things which should fail: syscall arguments out-of-bounds,
negative syscall args, etc. invalid fd. valid fd but for the wrong type
of file.
- if you can, something which will test the 32bit->64bit->32bit
conversions which 32-bit userspace on 64-bit kernel needs to do.
Somehow, I knew I didn't have to ask :)
Here you go:
http://www.xmailserver.org/epoll_pwait_test.c
There is a problem with the test we have inside the kernel about the size
of sigset_t, from the kernel (8 bytes on i386) and the glibc one (128 bytes):
if (sigmask) {
if (sigsetsize != sizeof(sigset_t))
return -EINVAL;
if (copy_from_user(&ksigmask, sigmask, sizeof(ksigmask)))
return -EFAULT;
sigdelsetmask(&ksigmask, sigmask(SIGKILL) | sigmask(SIGSTOP));
sigprocmask(SIG_SETMASK, &ksigmask, &sigsaved);
}
ATM I left the check and I bolt 8 inside the test software, but this needs
nicer handling. Typical run will show:
[EMAIL PROTECTED]:~/tmp$ ./epoll_pwait_test
Testing from wrong epfd type : OK
Testing from closed epfd type : OK
Testing numevents <= 0 : OK
Testing numevents too big : OK
Testing wrong sigmask size : OK
Testing getevents when none available : OK
Testing getevents when one available : OK
Testing signal when blocked : OK
Testing signal when non blocked : OK
