The main changes are: 1) Fix cBPF splat triggered by skb not having a mac header, from Eric Dumazet. 2) Fix spurious packet loss in generic XDP when pushing packets out (note that native XDP is not affected by the issue), from Johan Almbladh. 3) Fix bpf_dynptr_{read,write}() helper signatures with flag argument before its set in stone as UAPI, from Joanne Koong. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: bpf: Add flags arg to bpf_dynptr_read and bpf_dynptr_write APIs bpf: Make sure mac_header was set before using it xdp: Fix spurious packet loss in generic XDP TX path ==================== Link: https://lore.kernel.org/r/20220708213418.19626-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
