Hi,

I just integrated changes from this commit for Kernel version 3.15

 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=
bd4cf0ed331a275e9bf5a49e6d0fd55dffc551b8



into Kernel version  3.10.0-514.21.1 that’s what Centos 7 uses out of the
box.

Besides changes on a couple of drivers  most of the changes are isolated.

I’ll try to compile bcc in Centos 7 to test these  features:



AF_PACKET (libpcap/tcpdump, cls_bpf classifier, netfilter's xt_bpf, team
driver's load-balancing mode…)



Kernel helpers



Are there any bcc tools in the old folder  to test these ?



Maybe is a lost of time backporting ebpf and the sane thing to do is just
to use the newer kernels, but at least this helps to get familiar with the
code.



The current code is in this GitHub repo

linux-3.10.0-514.21.1.el7.x86_64





Bests
