Hi, The reproducer calls the methods bpf_prog_test_run_xdp and bpf_prog_test_run_skb. Both lead to the invocation of dev_map_enqueue, in the case of the former, the backtrace is recorded in its entirety, whereas for the latter it is not. I think the bug might be incorrectly reported on syzkaller, as during GDB debugging, the problem occurred in functions called from bpf_prog_test_run_skb. I also ran testing of my patch on syzkaller and the tests passed. Regards Michal
