Merge pull request #68 from vadorovsky/lsm 
Add support for raw tracepoint and LSM 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

meta: fix rust-analyzer support for aya-bpf 
Ironically, we have the same issue here as in https://github.com/aya-rs/aya-template/pull/13/.
This patch fixes this by explicitly defining the project layout for both vscode and neovim.

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.

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 69041954cb bpf: Added pinned constructor to maps 
Signed-off-by: Dave Tucker <dave@dtucker.co.uk>

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.
