Dave Tucker	74ae8ce271	test: Add regression tests ... This uses a mix of rust-script, bash, qemu and a test runner called RTF to add a regression test suite... and wires it into GitHub Actions Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Alessandro Decina	6316748ec1	Merge pull request #179 from dave-tucker/btf_datasec_name ... btf: Replace / in DATASEC before load to kernel	3 years ago
Alessandro Decina	b2182c6c4e	Merge pull request #177 from alessandrod/ptr-relocs ... relocate .text references	3 years ago
Alessandro Decina	f169a3fc6b	aya: fix func_info/line_info offsets ... Given the new start instruction offset, rebase func_infos and line_infos.	3 years ago
Alessandro Decina	8202105b7d	aya: relocate .text references ... Handle relocations against .text symbols in all instructions not just calls. Makes it so that let x = &some_function triggers linking of some_function in the current program and handles the resulting relocation accordingly. Among other things, enables the use of bpf_for_each_map_elem.	3 years ago
Dave Tucker	825bb3ad20	btf: Replace / in DATASEC before load to kernel ... This replaces the / character with a . which is allowed in the kernel names. Not allowing a forward slash is perhaps a kernel bug, but lets fix it up here as it's commonly used for Aya Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Dave Tucker	a1b46ece05	aya: Merge Fixup and Sanitzation to single step ... Aya will now perform sanitzation and fixups in a single phase, requiring only one pass over the BTF. This modifies the parsed BTF in place. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	06f8938808	Merge pull request #164 from dave-tucker/btf_verifier ... aya: Fix BTF verifier output	3 years ago
Dave Tucker	5d8b279265	aya: Fix BTF verifier output ... Currently errors can occur if the verifier output is > buffer as we get ENOMEM. We should only provide a log_buf if initial load failed, then retry up to 10 times to get full verifier output. To DRY this logic it has been moved to a function so its shared with program loading Signed-off-by: Dave Tucker <dave@dtucker.co.uk> one verifier loop to rule them all Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

Alessandro Decina	9ba2e147a1	btf: fixup func protos ... If an argument has a type, it must also have a name, see btf_func_check in the kernel. Given: SEC("lsm/syslog") int BPF_PROG(syslog_audit, int type, int ret_prev) { return 0; } Fixes: error: BTF error: the BPF_BTF_LOAD syscall failed.

Alessandro Decina	6a91fdf5a7	Merge pull request #157 from dave-tucker/doc-aya ... aya: document the public api	3 years ago
Dave Tucker	686ce45f93	aya: Fix BTF type resolution for Arrays and Ints ... The union of `size` and `type` is unused in BTF_KIND_ARRAY. Type information of elements is in the btf_array struct that follows in the type_ field while the index type is in the index_type field. For BTF_KIND_INT, only the offset should be compared and size and signedness should be ignored. Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago

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
