Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) API fixes for libbpf's BTF mapping of map key/value types in order
to make them compatible with iproute2's BPF_ANNOTATE_KV_PAIR()
markings, from Martin.
2) Fix AF_XDP to not report POLLIN prematurely by using the non-cached
consumer pointer of the RX queue, from Björn.
3) Fix __xdp_return() to check for NULL pointer after the rhashtable
lookup that retrieves the allocator object, from Taehee.
4) Fix x86-32 JIT to adjust ebp register in prologue and epilogue
by 4 bytes which got removed from overall stack usage, from Wang.
5) Fix bpf_skb_load_bytes_relative() length check to use actual
packet length, from Daniel.
6) Fix uninitialized return code in libbpf bpf_perf_event_read_simple()
handler, from Thomas.
