That said, a sleepable tracing prog is allowed to\nattach to a bpf prog target whose name has \u0027__x64_\u0027-alike prefix.\n\nFor example, a sleepable fentry prog attaches to a \u0027__x64_sys_nop\u0027 XDP\nprog, and copies buffer from a user pointer with bpf_copy_from_user()\nhelper. After attaching the XDP prog to lo interface, the kernel BUG\ncould be triggered by \u0027ping -c 1 -W 1 127.0.0.1\u0027:\n\n[    3.460756] BUG: sleeping function called from invalid context at kernel/bpf/trampoline.c:1324\n\nFix it by disallowing sleepable prog always when its target\nbtf is not a kernel\u0027s btf."
