The main changes are: 1) Reject bogus use of vmlinux BTF as map/prog creation BTF, from Alexei Starovoitov. 2) Fix allocation failure splat in x86 JIT for large progs. Also fix overwriting percpu cgroup storage from tracing programs when nested, from Yonghong Song. 3) Fix rx queue retrieval in XDP for multi-queue veth, from Maciej Fijalkowski. 4) Fix bpf_check_mtu() helper API before freeze to have mtu_len as custom skb/xdp L3 input length, from Jesper Dangaard Brouer. 5) Fix inode_storage's lookup_elem return value upon having bad fd, from Tal Lossos. 6) Fix bpftool and libbpf cross-build on MacOS, from Georgi Valkov. ==================== Signed-off-by: David S.
