Hi David,

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

The main changes are:

1) Fix nfp to allow zero-length BPF capabilities, meaning the nfp
   capability parsing loop will otherwise exit early if the last
   capability is zero length and therefore driver will fail to probe
   with an error such as:

     nfp: BPF capabilities left after parsing, parsed:92 total length:100
     nfp: invalid BPF capabilities at offset:92

   Fix from Jakub.

2) libbpf's bpf_object__open() may return IS_ERR_OR_NULL() and not
   just an error. Fix libbpf's bpf_prog_load_xattr() to handle that
   case as well, also from Jakub.

Please consider pulling these changes from:

Thanks a lot!
