Jesper Dangaard Brouer bc56c919fc bpf: Add xdp.frame_sz in bpf_prog_test_run_xdp(). ... Update the memory requirements, when adding xdp.frame_sz in BPF test_run function bpf_prog_test_run_xdp() which e.g. is used by XDP selftests. Specifically add the expected reserved tailroom, but also allocated a larger memory area to reflect that XDP frames usually comes in this format. Limit the provided packet data size to 4096 minus headroom + tailroom, as this also reflect a common 3520 bytes MTU limit with XDP. Note that bpf_test_init already use a memory allocation method that clears memory. Thus, this already guards against leaking uninit kernel memory.
