Toke Høiland-Jørgensen 7ac7830af6 bpf: Resolve fext program type when checking map compatibility ... [ Upstream commit 1c123c567f ] The bpf_prog_map_compatible() check makes sure that BPF program types are not mixed inside BPF map types that can contain programs (tail call maps, cpumaps and devmaps). It does this by setting the fields of the map->owner struct to the values of the first program being checked against, and rejecting any subsequent programs if the values don't match. One of the values being set in the map owner struct is the program type, and since the code did not resolve the prog type for fext programs, the map owner type would be set to PROG_TYPE_EXT and subsequent loading of programs of the target type into the map would fail. This bug is seen in particular for XDP programs that are loaded as PROG_TYPE_EXT using libxdp; these cannot insert programs into devmaps and cpumaps because the check fails as described above. Fix the bug by resolving the fext program type to its target program type as elsewhere in the verifier. v3: - Add Yonghong's ACK Fixes: f45d5b6ce2 ("bpf: generalise tail call map compatibility check") Acked-by: Yonghong Song <yhs@fb.com> Signed-off-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/r/20221214230254.790066-1-toke@redhat.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2023-01-07 11:11:41 +01:00
