Dave Tucker	5789585994	ebpf: Add example ... This ensures that macro expansion works properly and that expanded code compiles Signed-off-by: Dave Tucker <dave@dtucker.co.uk>	3 years ago
Dave Tucker	5d82d9a73e	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	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>	3 years ago
Michal Rostecki	70b4e68130	common: Bump the buffer size ... 1024 is too small for many kernel string limits (i.e. PATH_MAX, which is 4096). Signed-off-by: Michal Rostecki <vadorovsky@gmail.com>	3 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.
