2024-06-04ebpf: Return 0 when configuration failsAkihiko Odaki
The kernel interprets the returned value as an unsigned 32-bit so -1 will mean queue 4294967295, which is awkward. Return 0 instead. Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2024-06-04ebpf: Fix RSS error handlingAkihiko Odaki
calculate_rss_hash() was using hash value 0 to tell if it calculated a hash, but the hash value may be 0 on a rare occasion. Have a distinct bool value for correctness. Fixes: f3fa412de2 ("ebpf: Added eBPF RSS program.") Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2024-03-12ebpf: Updated eBPF program and skeleton.Andrew Melnychenko
Updated section name, so libbpf should init/gues proper program type without specifications during open/load. Also, added map_flags with explicitly declared BPF_F_MMAPABLE. Added check for BPF_F_MMAPABLE flag to meson script and requirements to libbpf version. Also changed fragmentation flag check - some TCP/UDP packets may be considered fragmented if DF flag is set.

2023-03-10ebpf: fix compatibility with libbpf 1.0+Shreesh Adiga
The current implementation fails to load on a system with libbpf 1.0 and reports that legacy map definitions in 'maps' section are not supported by libbpf v1.0+. This commit updates the Makefile to add BTF (-g flag) and appropriately updates the maps in rss.bpf.c and update the skeleton file in repo.

2021-06-04ebpf: Added eBPF RSS loader.Andrew Melnychenko
Added function that loads RSS eBPF program. Added stub functions for RSS eBPF loader. Added meson and configuration options. By default, eBPF feature enabled if libbpf is present in the build system. libbpf checked in configuration shell script and meson script.
