Error when running wallet in Gramine (Intel SGX)

[yagop]

I'm trying to run monero-wallet-rpc in Gramine as for security purposes.

The http request are not working (it receives and close them), and errors got shadowed so not sure what's going on. Neither writing logs to log file seems working.

$ gramine-sgx /etc/gramine/monero-wallet --wallet-dir=/home/monero/wallet/ --rpc-bind-port=18083 --rpc-bind-ip=127.0.0.1 --disable-rpc-login --rpc-ssl disabled --offline --non-interactive --log-level=4 --log-file=/home/monero/monero-wallet.log --stagenet

Any idea how to proceed?

Very interesting question. I will try Grammine myself.

But honestly I don't think this will be related to Monero code base. The error happens on much lower level (epoll syscall). There is all sort of restriction in SGX runtime.
