Hi David, The following pull-request contains BPF updates for your *net-next* tree. We've added 37 non-merge commits during the last 1 day(s) which contain a total of 67 files changed, 741 insertions(+), 252 deletions(-). The main changes are: 1) bpf_xdp_adjust_tail() now allows to grow the tail as well, from Jesper. 2) bpftool can probe CONFIG_HZ, from Daniel. 3) CAP_BPF is introduced to isolate user processes that use BPF infra and to secure BPF networking services by dropping CAP_SYS_ADMIN requirement in certain cases, from Alexei. Please consider pulling these changes from: git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git Thanks a lot!
