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	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. Aya-based project to test this change: https://github.com/vadorovsky/aya-log-example Fixes: #4 Signed-off-by: Michal Rostecki <vadorovsky@gmail.com> Signed-off-by: Tuetuopay <tuetuopay@me.com> Co-authored-by: Tuetuopay <tuetuopay@me.com>	3 years ago
