Hi David, hi Jakub, hi Paolo, hi Eric,

The following pull-request contains BPF updates for your *net* tree.

We've added 5 non-merge commits during the last 1 day(s) which contain
a total of 5 files changed, 77 insertions(+), 4 deletions(-).

The main changes are:

1) Fix BPF verifier to check bpf_func_state->callback_depth when pruning
   states as otherwise unsafe programs could get accepted, from Eduard Zingerman.

2) Fix to zero-initialise xdp_rxq_info struct before running XDP program in
   CPU map which led to random xdp_md fields, from Toke Høiland-Jørgensen.

3) Fix bonding XDP feature flags calculation when bonding device has no
   slave devices anymore, from Daniel Borkmann.

Thanks a lot!
