Dave Tucker	0c25d8655e	Add Tests ... This moves a large chunk of code from ebpf to shared so we can re-use write_record_header and write_record_message and friends so that we can write test cases to ensure that logs are properly formatted given certain input.

Michal Rostecki	9be90f8a74	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>	4 years ago
Alessandro Decina	223e2f4ea1	ebpf: inline write_record_header ... This seems to help the verifier keep track of where we're writing into LOG_BUF	4 years ago
Michal Rostecki	ec31526de1	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.
