Dear all,
it appears as if kFreeBSD is not able to set owners
of file descriptors. My kernel is 9.0-2-amd64 and
libc is 2.13-38, from the Wheezy release.
The snippet bellow claims owner 0 (naught) every
time it is executed with GNU/kFreeBSD:
pid 1234, owner 0
Test runs on GNU/Linux, OpenSolaaris, NetBSD, and
FreeBSD 9.0 all produce identical value of "pid2"
and "owner":
pid 1234, owner 1234
I initially detected this failure with TCP sockets,
but the snippet below is clearly sufficient as test.
Best regards,
Mats E A
============== example code ================
#include <stdio.h>
#include <fcntl.h>
int
main(void)
{
fcntl(0, F_SETOWN, getpid());
printf("pid %d, owner %d\n",
getpid(), fcntl(0, F_GETOWN, 0));
return 0;
}
