Michal Rostecki	628b473e09	ebpf: Ensure the bounds of log buffer ... eBPF verifier rejects programs which are not checking the bounds of the log buffer before writing any arguments. This change ensures that written log arguments. In practice, it means that doing this kind of checks is not going to be needed in eBPF program code anymore: 33a1aee2ea/echo-ebpf/src/main.rs (L47) Tested on: 876f8b4551 Signed-off-by: Michal Rostecki <vadorovsky@gmail.com>	2 years ago

Michal Rostecki	ca1fe7e05f	Format arguments in userspace ... This change moves away argument formatting from eBPF to the userspace. eBPF part of aya-log writes unformatted log message and all arguments to the perf buffer and the userspace part of aya-log is formatting the message after receiving all arguments.

Joel Höner	da13143c05	bpf: add `bpf_printk!` helper ... The `bpf_printk!` macro is a helper providing a convenient way to invoke the `bpf_trace_printk` and `bpf_trace_vprintk` BPF helpers. It is implemented as a macro because it requires variadic arguments.	2 years ago

Dave Tucker	f976229477	Support BTF Maps ... This commit allows for BTF maps in the .maps ELF section to be parsed. It reads the necessary information from the BTF section of the ELF file. While the btf_ids of Keys and Values types are stored, they are not (yet) used. When creating a BTF map, we pass the btf_key_type_id and btf_value_type_id.

Michal Rostecki	c6e1d56684	bpf: Add `load_bytes` method to SKB context ... This new method allows to load bytes into the given bytes slice, not requiring to alloate the memory on stack.

Michal Rostecki	a3a96b8415	bpf: Change the result type of bpf_get_current_comm helper ... Change it from `[i8; 16]` to `[u8; 18]`. `i8` arrays cannot be easily used in Rust for converting to string (i.e. with `core::str::from_utf8_unchecked`) and developers have to convert them themselves with unsafe code. Using u8 arrays lets developers to just convert it with `core::str::from_utf8_unchecked` without any limitations.

Michal Rostecki	bebe98e670	aya: Raise the warning when RMILIT_MEMLOCK is not RLIM_INFINITY ... Kernels before 5.11 don't use cgroup accounting, so they might reach the RLIMIT_MEMLOCK when creating maps. After this change, we raise a warning recommending to raise the RLIMIT_MEMLOCK.	2 years ago
Dave Tucker	555833a79a	Merge pull request #335 from dave-tucker/rust-runner ... test: Replace RTF with Rust	2 years ago
Dave Tucker	79101e748a	test: Replace RTF with Rust ... This commit replaces the existing RTF test runner with a simple rust binary package called - integration-test. integration-test depends on integration-ebpf, which contains test eBPF code written in Rust and C. `cargo xtask build-integration-test-ebpf` can be used to build this code and supress rust-analyzer warnings. It does require `bpf-linker`, but that is highly likely to be available to developers of Aya. It also requires a checkout of `libbpf` to extract headers like bpf-helpers.h. Since everything is compiled into a single binary, it can be run be run locally using `cargo xtask integration-test` or remotely using `./run.sh` which re-uses the bash script from the old test framework to spawn a VM in which to run the tests.
