Andre Fredette af3de84b08 Use a struct for setting priority and handle in SchedClassfier attach 
Use a struct called TcOptions for setting priority and handle in SchedClassifier attach

struct TcOptions implements the Default trait, so for the simple use
case in which the defaults are acceptable, we can call attach as
follows:
attach(“eth0”, TcAttachType::Ingress, TcOptions::default())

To specify all options:
attach(“eth0”, TcAttachType::Ingress, TcOptions { priority: (50), handle: (3) })

Or, some options:
attach(“eth0”, TcAttachType::Ingress, TcOptions { priority: (50), ..Default::default() })

Andre Fredette ac07608b79 Support using handle in tc programs 
Implements step 1 of https://github.com/aya-rs/aya/issues/414.

- Adds handle to the SchedClassifier attach API
- Saves handle in the TcLink sruct and uses it when detaching programs

NOTE: this changes the API, so it will require a bump in the Aya version.

Andrew Stoycos 893f9f44a2 Implement Copy for MapData 
Implement Copy for MapData so that
when `take_map` is used we create a
1 to 1 mapping of MapData to internal
FileDescriptor.  This will ensure
that when MapData is used in multiple
tasks that we don't drop the FD before
all tasks are done using it.

Andrew Stoycos 1aefa2e5e6 Core refactor of Map API 
Build completing tests passing

Refactor the Map API to better align
with the aya programs API.  Specifically
remove all internal locking mechanisms
and custom Deref/DerefMut implementations.
They are replaced with a Map enum
and AsRef/AsMut implementations.

All Try_From implementations have been moved
to standardized enums, with a slightly
special one for PerfEventArray's.

Also cleanup/fix all associated tests and
documentation.

Dave Tucker 95e8c78db8 docs: Add labels for optional features 
Following the lead of crates like tokio and nix, we now annotate APIs
that require optional features. This helps in cases where a user wants
to have an `AsyncPerfEventArray` which is documented on crates.io, but
it's not obvious that you have to enable the `async` feature.

Michal Rostecki 43aff57793 maps: Disable miri warnings about integer-to-pointer conversions 
`override_syscall` performs integer-to-pointer conversion. This is
considered harmful on the newest Rust nightly which provides
`ptr::from_exposed_addr`, but there is no other way on Rust stable than
doing `as *const T`, which is what miri is unhappy about.

aztecher 2eccf1d57d aya: add BpfLoader::set_max_entries 
Add BpfLoader::set_max_entries, which sets the max_entries for the
specified map, as the load-time option.
The max_entries set at map initialization in the ebpf component can be
overwritten by this method called on the userspace component.
If you want to set max_entries for multiple maps in an ebpf component,
you can do so by calling set_max_entries in the form of a method chain.

from pinned points in the bpffs and
`from_fd` to allow loading BPF maps from
RawFds aquired via some other means eg

but will be the future abstraction once
all bpf maps are represented as an enum.

Since we support multiple maps in the same section, the section_index is
no longer a unique way to identify maps. This commit uses the symbol
index as the identifier, but falls back to section_index for rodata
and bss maps since we don't retrieve the symbol_index during parsing.

Merge pull request #249 from alessandrod/new-links 
aya: rework links
 3 years ago
Alessandro Decina cb57d10d25 aya: rework links 
Remove LinkRef and remove the Rc<RefCell<_>> that was used to store
type-erased link values in ProgramData. Among other things, this allows
`Bpf` to be `Send`, which makes it easier to use it with async runtimes.

Change the link API to:

    let link_id = prog.attach(...)?;
    ...
    prog.detach(link_id)?;

Link ids are strongly typed, so it's impossible to eg:

    let link_id = uprobe.attach(...)?;
    xdp.detach(link_id);

As it would result in a compile time error.

Links are still stored inside ProgramData, and unless detached
explicitly, they are automatically detached when the parent program gets
dropped.

Dave Tucker f357be7db4 aya: Support multiple maps in map sections 
This commit uses the symbol table to discover all maps inside an ELF
section. Instead of doing what libbpf does - divide the section data
in to equal sized chunks - we read in to section data using the
symbol address and offset, thus allowing us to support definitions
of varying lengths.

Alessandro Decina ad1636d2e7 aya: perf_buffer: call BytesMut::reserve() internally 
This changes PerfBuffer::read_events() to call BytesMut::reserve()
internally, and deprecates PerfBufferError::MoreSpaceNeeded.

This makes for a more ergonomic API, and allows for a more idiomatic
usage of BytesMut. For example consider:

    let mut buffers = vec![BytesMut::with_capacity(N), ...];
    loop {
        let events = oob_cpu_buf.read_events(&mut buffers).unwrap();
        for buf in &mut buffers[..events.read] {
            let sub: Bytes = buf.split_off(n).into();
            process_sub_buf(sub);
        }
        ...
    }

This is a common way to process perf bufs, where a sub buffer is split
off from the original buffer and then processed. In the next iteration
of the loop when it's time to read again, two things can happen:

- if processing of the sub buffer is complete and `sub` has been
dropped, read_events() will call buf.reserve(sample_size) and hit a fast
path in BytesMut that will just restore the original capacity of the
buffer (assuming sample_size <= N).

- if processing of the sub buffer hasn't ended (eg the buffer has been
stored or is being processed in another thread),
buf.reserve(sample_size) will actually allocate the new memory required
to read the sample.

In other words, calling buf.reserve(sample_size) inside read_events()
simplifies doing zero-copy processing of buffers in many cases.

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:

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.

that attached them was killed.

internally to simplify the common case.
