I've not looked at kernel sources, but isn't JITing done when attaching filter to socket? And later this sysctl variable takes no effect? so we could do: - enable JIT if not enabled - pcap_setfilter(pcap, program) - disable JIT if enabled - drop privilages It's a little racy, but well... ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev@wireshark.org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe
