Hi!
This series is my stab at what was discussed at a recent IOvisor
bi-weekly call. The idea is to make the device translator run at
the program load time. This makes the offload more explicit to
the user space. It also makes it easy for the device translator
to insert information into the original verifier log.
v2:
- include linux/bug.h instead of asm/bug.h;
- rebased on top of Craig's verifier fix (no changes, the last patch
just removes more code now). I checked the set doesn't conflict
with Jiri's, Josef's or Roman's patches, but missed Craig's fix :(
v1:
- rename the ifindex member on load;
- improve commit messages;
- split nfp patches more.
Jakub Kicinski (15):
net: bpf: rename ndo_xdp to ndo_bpf
bpf: offload: add infrastructure for loading programs for a specific
netdev
bpf: report offload info to user space
bpftool: print program device bound info
xdp: allow attaching programs loaded for specific device
cls_bpf: allow attaching programs loaded for specific device
nfp: bpf: drop support for cls_bpf with legacy actions
nfp: bpf: remove the register renumbering leftovers
nfp: bpf: remove unnecessary include of nfp_net.h
nfp: bpf: refactor offload logic
nfp: bpf: require seamless reload for program replace
nfp: bpf: move program prepare and free into offload.c
nfp: bpf: move translation prepare to offload.c
nfp: bpf: move to new BPF program offload infrastructure
bpf: remove old offload/analyzer
