Bug description:
The psock_tpacket in the net test from ubuntu_kernel_selftests failed with
B-KVM
$ sudo ./psock_tpacket
test: TPACKET_V1 with PACKET_RX_RING open: No such file or directory
Look into the code, it seems that this file not found error is caused
by the attempt to access /proc/kallsyms in test_kernel_bit_width():
static int test_kernel_bit_width(void)
{
char in[512], *ptr;
int num = 0, fd;
ssize_t ret;
fd = open("/proc/kallsyms", O_RDONLY);
if (fd == -1) {
perror("open");
exit(1);
}
