Error: `Option::unwrap()` on a `None` value'

[fantas1a]

Hi, I wonder if anyone can help with the following errors. I run SODA with one master and two slave nodes, and all with scalable SGX.

name@master:~/soda/bin$ sudo ./app 15:34:24 [ INFO] starting local_fs_reader<bytes> job thread_id = 139655171670016 finish pre_touching local_scheduler serialize task time: 0.002882157 s local_scheduler deserialize task time: 7.3917e-5 s tid: 11, at the begining of secure execution thread '' panicked at 'called Option::unwrap() on a None value', src/lib.rs:244:72 Illegal instruction

Here is my node configuration:

master = "10.0.0.5:3000" slaves = ["user@10.0.0.6", "user@10.0.0.7"]

My machine:

ubuntu 20.04 with SGX v2, every nodes can ssh each other without password

And following is what I did:

1. Install rustup from its website by command: $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
2. Install 2.14 version SGX (sdk, psw, driver)
3. Run the first 2 commands from spark vega (https://rajasekarv.github.io/vega/): $ rustup toolchain install nightly $ rustup default nightly
4. Install Cap'n Proto by: $ apt-get install capnproto
5. Paste Cargo.lock from this issue (https://github.com/tsinghua-ideal/flare/issues/3)
6. Compile by type: $ make
7. It prompts rustfmt is not available in this nightly version, suggest if I do not need rustfmt, I can use minimal installation. Otherwise, use the most update rustup this year. I use the suggested commands to use minimal installation.

It prompted: info: syncing channel updates for 'nightly-2021-03-30-x86_64-unknown-linux-gnu' info: latest update on 2021-03-30, rust version 1.53.0-nightly (48691ea6e 2021-03-29) error: component 'rustfmt' for target 'x86_64-unknown-linux-gnu' is unavailable for download for channel 'nightly-2021-03-30' Sometimes not all components are available in any given nightly. If you don't need the component, you could try a minimal installation with:

rustup toolchain add nightly-2021-03-30 --profile minimal

If you require these components, please install and use the latest successful build version, which you can find at https://rust-lang.github.io/rustup-components-history.

After determining the correct date, install it with a command such as:

rustup toolchain install nightly-2018-12-27

Then you can use the toolchain with commands such as:

cargo +nightly-2018-12-27 build

make: *** [Makefile:279: clean] Error 1

I type in:

rustup toolchain add nightly-2021-03-30 --profile minimal

8. Compile again by type: $ make
9. Make succeed. Copy the same hosts.conf file to every nodes at their /root/
10. Run on every nodes: $ source ~/flare/bin/set_env_dist.sh
11. Run on master node: $ sudo ~/flare/bin/app

I have same error when in local mode:

05:19:43 [ INFO] starting local_fs_reader<bytes> job thread_id = 140685963821056 finish pre_touching local_scheduler serialize task time: 0.0030098890000000004 s local_scheduler deserialize task time: 8.0407e-5 s tid: 11, at the begining of secure execution thread '' panicked at 'called Option::unwrap() on a None value', src/lib.rs:244:72 Illegal instruction

And the hosts.conf file I used when in local mode:

master = "10.0.0.6:3000" slaves = [""]

I executed the ~/flare/bin/set_env_distri.sh in advance.

@AmbitionXiang Hearty thanks if you could take a look at this : )

And if I test with se1_sec()?; se2_sec()?; se3_sec()?; in app/src/main.rs, it prompted:
