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	6539cbb555	aya/aya-bpf: implement btf tracepoint programs	3 years ago
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

Tw	d1b7b024dc	bpf: fix a minor bug due to stackid allocation ... The type casting introduces an allocation, this will cause compiling failure when linking final bpf target. So remove this casting to fix this issue. BTW, the following is the failure I met: = note: 07:24:12 [ERROR] fatal error: "unable to allocate function return #1" PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
