Dave Tucker	5c6131afba	Add BPF_PROG_TYPE_EXT ... This requires loading the BTF to kernel when loading all programs as well as implementing Extension program type Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	379bb313b1	obj: Add Btf::to_bytes ... This allows for parsed BTF to be re-encoded such that it could be loaded in to the kernel. It moves bytes_of to the utils package. We could use Object::bytes_of, but this requires the impl of the Pod trait on generated code. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	65a0b83205	Mark .rodata maps as readonly and freeze on load ... This commit marks .rodata maps as BPF_F_RDONLY_PROG when loaded to prevent a BPF program mutating them. Initial map data is populated by the loader using the new `BpfLoader::set_global()` API. The loader will mark is marked as frozen using bpf_map_freeze to prevent map data being changed from userspace. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Michal Rostecki	7e2fcd1d6d	Support for fentry and fexit programs ... fentry and fexit programs are similar to kprobe and kretprobe, but they are newer and they have practically zero overhead to call before or after kernel function. Also, fexit programs are focused on access to arguments rather than the return value. Those kind of programs were introduced in the following patchset: https://lwn.net/Articles/804112/ Signed-off-by: Michal Rostecki <mrostecki@opensuse.org>	3 years ago

Thia Wyrod	18970369e2	aya: Remove unnecessary unsafe markers on map iteration. ... Map iteration can yield stale keys and values by virtue of sharing a data structure with BPF programs which can modify it. However, all accesses remain perfectly safe and will not cause memory corruption or data races.	3 years ago

Thia Wyrod	f56dd0a70b	aya: eliminate name duplication in maps and programs. ... Map and ProgramData objects had unnecessarily cloned strings for their names, despite them being just as easily available to external users via bpf.maps() and bpf.programs().	3 years ago

Dave Tucker	e4d9774bf7	obj: Improve section detection ... This commit improves section detection. Previously, a section named "xdp_metadata" would be interpretted as a program section, which is incorrect. This commit first attempts to identify a BPF section by name, then by section.kind() == SectionKind::Text (executable code). The computed section kind is stored in the Section so variants can be easily matched on later. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
