Alessandro Decina	eb654d1e3e	xtask: codegen: fix bindings for archs other than x86	3 years ago
Alessandro Decina	3d72414fde	Merge pull request #86 from willfindlay/bpf_probe_read_str ... aya-bpf/helpers: add documentation and implement more bpf_probe_read_* wrappers	3 years ago
William Findlay	4a02d0038f	aya-bpf/helpers: add documentation and implement all bpf_probe_read_* wrappers ... This patch adds some documentation to aya-bpf/helpers and adds documentation for the module itself and for all of the wrappers currently defined in the module. It also implements the rest of the bpf_probe_read_* wrappers that were missing from this file. In the future, it probably also makes sense to add some bpf_probe_read_* wrappers that can read directly into a map pointer, avoiding the BPF stack altogether. I'm going to call this out of scope for this PR, but plan to submit a subsequent one that addresses this use case. Signed-off-by: William Findlay <william@williamfindlay.com>	3 years ago

William Findlay	b30fd424ef	aya-bpf/helpers: expose raw bindings through helpers::gen ... Until we add another set of bpf_probe_read_* wrappers for reading into a map pointer, users need access to the underlying bpf_probe_read helper, which is clobbered by this module. This patch enables direct access to the underlying helpers::gen module to support such use cases. In my view, it would also probably make sense to just not export helpers::gen::* and force the user to opt into helpers::gen, but this can be decided on later.

William Findlay	169478c863	Add support for raw tracepoint and LSM programs ... This change adds support for the following program types: * raw tracepoint * LSM Supporting LSM programs involved a necessity of supporting more load_attrs for the BPF_PROG_LOAD operation, concretely: * expected_attach_type - for LSM programs, it has always to be set to BPF_LSM_MAC * attach_btf_obj_fd - it's often used to reference the file descriptor of program's BTF info, altough in case of LSM programs, it only has to contain the value 0, which means the vmlinux object file (usually /sys/kernel/btf/vmlinux) * attach_btf_id - ID of the BTF object, which in case of LSM programs is the ID of the function (the LSM hook) The example of LSM program using that functionality can be found here: https://github.com/vadorovsky/aya-example-lsm Fixes: #9 Signed-off-by: William Findlay <william@williamfindlay.com> Signed-off-by: Michal Rostecki <mrostecki@opensuse.org>	3 years ago

William Findlay	99f6f9e14d	aya: fix include_bytes_aligned! macro to work in some corner cases ... I found a corner case in my own development workflow that caused the existing macro to not work properly. The following changes appear to fix things. Ideally, we could add some test cases to CI to prevent regressions. This would require creating a dedicated directory to hold test cases so that we can "include" them at compile time.	3 years ago
Alessandro Decina	a94774755f	Merge pull request #76 from willfindlay/load_include_bytes ... aya: introduce include_bytes_aligned!() macro	3 years ago
William Findlay	4df4e9c14e	aya: introduce include_bytes_aligned!() macro ... This is a helper macro that can be used to include bytes at compile-time that can then be used in Bpf::load(). Unlike std's include_bytes!(), this macro also ensures that the resulting byte array is correctly aligned so that it can be parsed as an ELF binary.

Dave Tucker	9426f36f79	Implement Pinning For Programs and Maps ... This commit adds 2 new methods to aya::sys - bpf_pin_object - bpf_get_object Which allow the pinning and retrieval of programs/maps to bpffs. It adds a `Program.pin` API, such that a loaded program can be pinned. For map pinning, the user must ensure the `pinning u32` in the `bpf_map_def` is set to 1, maps will be pinned using a new builder API. BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o") This will pin all maps whose definition requests pinning to path + name.
