The issue can be described as\nfollows:\n\n__cgroup_bpf_detach\n update_effective_progs\n compute_effective_progs\n bpf_prog_array_alloc <-- fault inject\n purge_effective_progs\n /* change to dummy_bpf_prog */\n array->items[index] = &dummy_bpf_prog.prog\n\n---softirq start---\n__do_softirq\n ...\n __cgroup_bpf_run_filter_skb\n __bpf_prog_run_save_cb\n bpf_prog_run\n stats = this_cpu_ptr(prog->stats)\n /* invalid memory access */\n flags = u64_stats_update_begin_irqsave(&stats->syncp)\n---softirq end---\n\n static_branch_dec(&cgroup_bpf_enabled_key[atype])\n\nThe reason is that fault injection caused update_effective_progs to fail\nand then changed the original prog into dummy_bpf_prog.prog in\npurge_effective_progs. Then a softirq came, and accessing the members of\ndummy_bpf_prog.prog in the softirq triggers invalid mem access.\n\nTo fix it, skip updating stats when stats is NULL." } ], "affected": [ {
