fixcik / occlum-chdb

I try to run chdb in occlum

Build

docker build . -t occlum-sample

Run

docker run --rm --privileged -v /var/run/aesmd/aesm.socket:/var/run/aesmd/aesm.socket occlum-sample

I catch this error:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Error { inner: Embedded((EINVAL, "invalid start or end")), location: Some(ErrorLocation { line: 12, file: "src/vm/vm_range.rs" }), cause: None }', src/vm/vm_manager.rs:872:80

I fix by adding capget syscall: https://github.com/aggregion/occlum/blob/aggregion/src/libos/src/process/syscalls.rs#L547-L559
