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.
