Hi, I want to use BPF JIT Kernel APIs in FreeBSD(like: bpf_jitter(), etc..), for implementing TCP connection packet filtering. I have followed below instructions as specified in: https://lists.freebsd.org/pipermail/freebsd-current/2005-December/058603.html STEPS followed: --------------------- cp /usr/src/sys/amd64/conf/GENERIC /usr/src/sys/amd64/conf/MYKERNEL And added below line in MYKERNEL config file. options BPF_JITTER make buildkernel KERNCONF=MYKERNEL make installkernel KERNCONF=MYKERNEL reboot But after reboot the flag BPF_JITTER is not getting enabled(all the code inside "#ifdef BPF_JITTER" is not getting executed). Am I missing something? Also it looks like there are not many updates to BPF JIT code since 2005, is it stable? anyone using it? Thanks, Krishna.help
