Subject: [Wireshark-dev] Enabling linux kernel jit compiler from dumpcap?

Hi
Should we add code to enable the JIT compiler from dumpcap?

> From netsniff-ng bpf.c<http://lingrok.org/xref/netsniff-ng/bpf.c>

int enable_kernel_bpf_jit_compiler(void)
{
                int fd;
                ssize_t ret;
                char *file = "/proc/sys/net/core/bpf_jit_enable";

                fd = open(file, O_WRONLY);
                if (unlikely(fd < 0))
                                return -1;

                ret = write(fd, "1", strlen("1"));

                close(fd);
                return ret;
}

Regards
Anders
