William Findlay	b28ae97053	bpf/macros: fix tests ... Doctests were broken due to depencencies on a generated vmlinux, incorrect function signatures, and a missing unsafe keyword.	3 years ago

William Findlay	ff14493751	bpf/maps: implement ProgramArray ... This PR implements the ProgramArray map type in aya-bpf. Includes a convenient tail_call method that wraps the bpf_tail_call helper.	3 years ago
Alessandro Decina	faa36763f7	Merge pull request #146 from dave-tucker/ro-maps ... Mark .rodata maps as readonly and freeze on load	3 years ago
Michal Rostecki	54377b6140	aya-bpf: Allow to convert probe arguments to mutable pointers ... Before this change, arguments fetched with `arg` from `ProbeContext` could be only fetched as const pointers. This change allows to get mut pointers as well.

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

Dave Tucker	23d1920854	codegen: add bindings for btf structs ... This adds `bpf_btf_info` which can be used to get BPF information via a syscall.

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	b655cf973f	aya-bpf: remove unnecessary unsafe markers on map functions. ... Map lookup and deletion can yield stale keys and values by virtue of sharing a data structure with userspace programs and other BPF programs which can modify it. However, all accesses remain perfectly safe and will not cause memory corruption or data races.	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
