Hi David,

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

The main changes are:

1) verifier precision propagation fix, from Andrii.

2) BTF size fix for typedefs, from Andrii.

3) a bunch of big endian fixes, from Ilya.

4) wide load from bpf_sock_addr fixes, from Stanislav.

5) a bunch of misc fixes from a number of developers.

Please consider pulling these changes from:
