Arch Linux

Description:
GHC does execute calls to setResourceLimits correctly on Archlinux , but does on other distributions. see the following samples:

-- snip
import System.Posix

kibi, mebi :: Integral a => a
kibi = 1024
mebi = kibi * kibi

main = do
setResourceLimit ResourceOpenFiles $
ResourceLimits (ResourceLimit 60)
(ResourceLimit 60)
-- snap
-- output snip:
a.out: setResourceLimit: invalid argument (Invalid argument)
-- snap

see this C program and note how it doesn't fail:

/* snip */
#include <sys/time.h>
#include <sys/resource.h>
#include <stdio.h>
#include <stdlib.h>

int main() {
struct rlimit rl = { 60, 60 };
if( setrlimit (RLIMIT_NOFILE, &rl) == -1) {
perror ("Error setting limit");
exit (-1);
}
return 0;
}
/* snap */


Additional info:
* package version(s)
i am using ghc 6.8.2

Steps to reproduce:
copy the code above (the first snipped) into a file pwns.hs and do:
# snip
runhaskell pwns.hs
# snap
see how it fails

Have a nice day, greez litb
