Some more updates on the BPF front-end to get further eBPF
functionality working with tc. See individual patches for
details. Targeted at iproute2's -next branch.
Thanks!
v1 -> v2:
- fix minor stylistic nit spotted by Sergei
Daniel Borkmann (5):
{f,m}_bpf: make tail calls working
{f,m}_bpf: check map attributes when fetching as pinned
{f,m}_bpf: allow for user-defined object pinnings
{f,m}_bpf: allow updates on program arrays
{f,m}_bpf: add more example code
