bpf program section names must be unique to prevent programs from appending to each other, so instead the bpf loader will strip everything past the final $ symbol when actually pinning the program into the filesystem. While at it add a little bit more logging. Example on aosp cuttlefish 5.4.30 virtual device: D LibBpfLoader: bpf_prog_load lib call for /system/etc/bpf/offload.o (schedcls_ingress_tether_ether) returned fd: 8 (no error) D LibBpfLoader: cs[1].name:schedcls_ingress_tether_rawip$stub min_kver:0 .max_kver:40e00 (kvers:5041e) D LibBpfLoader: cs[2].name:schedcls_ingress_tether_rawip$4_14 min_kver:40e00 .max_kver:ffffffff (kvers:5041e) D LibBpfLoader: bpf_prog_load lib call for /system/etc/bpf/offload.o (schedcls_ingress_tether_rawip$4_14) returned fd: 9 (no error) I bpfloader: Attempted load object: /system/etc/bpf/offload.o, ret: Success $ adb shell ls -l /sys/fs/bpf | egrep offload -rw-rw---- 1 root network_stack 0 2020-04-22 01:27 map_offload_tether_ingress_map -rw-rw---- 1 root network_stack 0 2020-04-22 01:27 map_offload_tether_stats_map -r--r----- 1 root root 0 2020-04-22 01:27 prog_offload_schedcls_ingress_tether_ether -r--r----- 1 root root 0 2020-04-22 01:27 prog_offload_schedcls_ingress_tether_rawip Test: builds, atest, proper program loaded on 5.4.30 aosp cuttlefish Signed-off-by: Maciej Żenczykowski <maze@google.com> Change-Id: Id3fcb8e2a6b0087f704e77726e9961efc6145739 |
