Johannes Edmeier	2d79f22b40	aya-bpf: use bpf_read_probe for reading pt_regs ... Linux Kernels < 5.5 don't support bpf_probe_read_kernel. Therefore bpf_probe_read must be used for compatibility reasons.	3 years ago
Dave Tucker	05c1586202	bpf: bpf_probe_read_kernel fields in pt_regs ... As it turns out, the verifier gets upset if you try to read the values directly without using bpf_probe_read. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	e3c8c659a1	bpf: arm fix pt_regs handling ... Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	218d4842d6	bpf: Be consistent with arm target_arch ... This is `arm` in bindings but `armv7` in args. Let's use `arm` Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	7f6da53c34	bpf: Fix pt_regs for aarch64 (again) ... Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Dave Tucker	4acd996cb8	bpf: Add PtRegs wrapper ... This adds a portable wrapper around pt_regs and user_pt_regs. It makes writing Raw Tracepoint or KProbe programs easier when the arguments are one of these types while also ensuring code is portable across architectures Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	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.

William Findlay	89dee1a114	aya-bpf: implement argument coercion for pt_regs and BTF programs ... Implements argument and return value coercion helpers for: - LSM programs - BTF tracepoints - [ku]{ret}probes Signed-off-by: William Findlay <william@williamfindlay.com>	3 years ago
