vscode: check all targets 
Now that building integration tests works out of the box, we can.

integration-test: build "fake" by default 
Use the environment variable AYA_BUILD_INTEGRATION_BPF to indicate to
the build script that it should *actually* build bpf, otherwise emitting
empty files.

This allows metadata builds to skip costly build steps without
sacrificing ergonomics; all compile-time tools such as cargo clippy work
out of the box.

Cargo even gives each of these builds (depending on the value of the
environment variable) its own cache key, so they do not invalidate each
other when the user alternates between metadata and real builds.

This allows the lint action to move out of the VM.

integration-test: compile C probes using build.rs 
- Add libbpf as a submodule. This prevents having to plumb its location
  around (which can't be passed to Cargo build scripts) and also
  controls the version against which codegen has run.
- Move bpf written in C to the integration-test crate and define
  constants for each probe.
- Remove magic; each C source file must be directly enumerated in the
  build script and in lib.rs.

Remove detritus 
- rustfmt settings are hierarchical.
- integration-ebpf is always compiled at a distance with flags provided.
- .cargo/config.toml is not respected except at the root of the
  workspace[0].

Clippy over tests and integration-ebpf 
Replace all `assert!(matches!(..))` with `assert_matches!(..)`.

Remove the now-unused build-integration-test xtask command whose logic
doesn't match that of the build-and-run command.

integration-test: Remove integration-test-macros 
This doesn't add any value; use `cargo build --tests` with
`--message-format=json` instead; parse the output using `cargo_metadata`
to discover the location of the test binary.

Move test/integration-test/src/tests -> test/integration-test/tests to
conform to
https://doc.rust-lang.org/book/ch11-03-test-organization.html#integration-tests.

Alessandro Decina 11c227743d bpf: improve bpf_probe_read_kernel_str_bytes and bpf_probe_read_user_str_bytes 
This change does a few things:

- it fixes a bug in the wrappers, where we were expecting the kernel to
  return len=1 for b"\0" where it instead returns 0 and doesn't write
  out the NULL terminator

- it makes the helpers more robust by hardcoding bound checks in
  assembly so that LLVM optimizations can't transform the checks in a
  way that the verifier can't understand.

- it adds integration tests

aya: Make FEATURES public
 1 year ago
Dave Tucker 47f764c191 aya: Make Features part of the public API 
This commit adds a new probe for bpf_attach_cookie, which would be used
to implement USDT probes. Since USDT probes aren't currently supported,
we this triggers a dead_code warning in clippy.

There are cases where exposing FEATURES - our lazy static - is actually
helpful to users of the library. For example, they may wish to choose to
load a different version of their bytecode based on current features.
Or, in the case of an orchestrator like bpfd, we might want to allow
users to describe which features their program needs and return nice
error message is one or more nodes in their cluster doesn't support the
necessary feature set.

To do this without breaking the API, we make all the internal members of
the `Features` and `BtfFeatures` structs private, and add accessors for
them. We then add a `features()` API to avoid leaking the
lazy_static.

aya: Remove iter_key from LPM Trie API
 1 year ago
Dave Tucker 00c480d2f9 aya: Remove iter_key from LPM Trie API 
Based on the discussion in Discord we've decided to drop the
iter_key() API for LPM Trie. According to the kernel self-tests and
experimentation done in Aya, providing a key into bpf_map_get_next_id
will either:

- If key is an EXACT match, proceed iterating through all keys in the
trie from this point
- If key is NOT an EXACT match, proceed iterating through all keys in
the trie starting at the leftmost entry.

An API in Aya could be crafted that gets the LPM match + less specific
matches for a prefix using these semantics BUT it would only apply to
userspace. Therefore we've opted out of fixing this.
