Good question. This would need further debugging.

I'm closing this issue as there were no updates for several months. @anjalirai-intel @jinengandhi-intel If this is still relevant, please provide additional details and reopen.

Looking at the PR that introduced `flock()` support, I don't see anything that could lead to increasing the file size: https://github.com/gramineproject/gramine/pull/1416 Can you debug a bit more: 1. What are...

@lead4good Any progress on debugging this? I don't see anything special in the https://github.com/gramineproject/gramine/commit/1ea3e60c2b52430cce04c741f2b79c4dc1316ff8 commit. I also don't understand how tmpfs (which uses buffers in enclave memory) relates to the...

We haven't observed this issue anywhere else, and there was no follow up for the last several months from the topic starter. I will close this issue. @fnerdman Feel free...

I confirm that this is indeed a (tiny) bug in Gramine. We do not have special casing of `INT_MIN` in the wait family of syscalls.

Yep, we have https://github.com/linux-test-project/ltp/tree/da2f34028f046a208aa2fed5e287df2538e69f91 (version `LTP 20200930`). This test `wait403` was added in [`LTP 20210927`](https://github.com/linux-test-project/ltp/releases/tag/20210927). So @anjalirai-intel was enabling this newer version of LTP (I think), and hit this case.

Jenkins, test this please (Jenkins was dead when this PR was created)

We always need to get the SGX Quote, no matter EPID or DCAP attestation. And the SGX Quote is generated by the Quoting Enclave (QE), with which Gramine needs to...
