bpf compilation using clang
Hi all,
I am trying to insert instructions into the bpf using the bpf syscall,
the instructions were generated using the following command line:
clang -I ~/Builds/bpf_rss/iproute2/include -Wall -target bpf -O2
-emit-llvm -c upstream/qemu/hw/net/rss_tap_bpf_program.c -o - | llc
-march=bpf -filetype=obj -o tap_bpf_program.o
and then were translated to bpf instructions using the BPFCparser tool
