Alessandro Decina 2cec04c578 bpf: add explicit BTF argument to the load API 
Add a `target_btf: Option<Btf>` argument to Bpf::load. None can be
passed to indicate to skip BTF relocation, for example for kernels that
don't support it. Some(btf) can be used to pass BTF parsed with
Btf::from_sys_fs() or Btf::parse/parse_file.

Finally, add a simpler Bpf::load_file(path) that uses from_sys_fs()
internally to simplify the common case.

threads.

Change the way maps are stored in the `Bpf` struct from RefCell to a
custom RwLock.

Alessandro Decina e83a26b307 probe: sysfs helpers don't need to be public 4 years ago
Alessandro Decina 54637eab04 Improve relocation errors 
Use BpfError::RelocationError for both maps and BTF relocations. The
error includes the name of the program that failed, and the source error
stored as Box<dyn Error>.

This hides the implementation details of the source errors - which are
unrecoverable anyway - while still allowing fine grained error messages.

Alessandro Decina b75efc8efe bpf: fix loading socket filters from obj files 4 years ago
Alessandro Decina a8c212377f bpf: make program() and program_mut() return inner program types 
program() and program_mut() are now generic and can return the inner
program type, which is what you want 99.999% of the time, eg:

    let prog = bpf.program_mut::<&mut Xdp>("foo")?.unwrap();
    prog.load()?;
    prog.attach("eth0")?;

The methods will fail if the requested program is not of the expected
type (eg if you try to retrieve a kprobe as an xdp program).

Alessandro Decina 4dc01f64dd bpf: make map() and map_mut() optionally return concrete map types 
map() and map_mut() used to return Ref<Map>, then to convert to a concrete
type you had to:

    let mut perf_map: PerfMap<_> = bpf.map_mut("PERF_MAP").unwrap().try_into()?;;

But the base Map type is pretty much only useful internally. This change
makes map() and map_mut() use TryInto internally, so that now
conversions can can be done with:

    let mut perf_map: PerfMap<_> = bpf.map_mut("PERF_MAP")?.unwrap();
