Hi all, I am trying to insert instructions into the bpf using the bof 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 Every time I try to insert the array of instructions the verfier fails with the following error: back-edge from insn 363 to 364 I am not sure how to debug this error since the instructions are in binary and the precompiled source code doesn't seem to contain any weird loops or jump to instructions... Is there a way to identify which line of source code is causing these errors? Thanks!
