[regression] Unable to initialize SGX enclaves with XFRM other than 3

[Jethro Beekman]

SRU Justification

[Impact]

In 5.15.0-1045, only loading enclaves with XFRM set to 3 works, sgx_encl_init returns EINVAL. The only reason this wouldn't work properly is if sgx_drv_init thinks XSAVE isn't enabled. This works fine in 5.15.0-1043.

Likely cause:
1045 adds this patch: https://github.com/torvalds/linux/commit/b81fac906a8f9e682e513ddd95697ec7a20878d4 . This later patch indicates that the former patch introduced some ordering problems. https://github.com/torvalds/linux/commit/2c66ca3949dc701da7f4c9407f2140ae425683a5 . That later patch isn't applied to 1045.

[Test Plan]

User test results pending, but its a fix commit so should likely be applied regardless.

[Regression Potential]

SGX could continue to fail.

Please try the referenced kernel jammy-azure-5.15.0-1049.56~lp2034745.1.tgz with the fix commit. Note that this kernel is not signed for a UEFI secure boot environment.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2034745

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I tested the changes today and was able to successfully run enclave in debug mode. Thanks a lot Tim.

Thanks Gaurav

[Fabian Grünbichler (f-gruenbichler)]

FWIW, this not only affects the 5.15/jammy kernel series, but also at least 6.2/lunar: https://github.com/openzfs/zfs/issues/15223 , and also affects non-SGX use cases like OpenZFS features that benefit from AVX support (raidz, encryption, ..)

[Tim Gardner (timg-tpi)]

Reposted the patch for all affected kernels: https://lists.ubuntu.com/archives/kernel-team/2023-September/142913.html

[Daniel Arai (danielarai)]

This also affects 5.4.0 from 5.4.0-158 on. Is this version getting a fix? It's not clear to me from the linked thread which kernel versions are getting fixes, given that focal supports both 5.4 and 5.15 kernels.

This bug is awaiting verification that the linux/5.15.0-88.98 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy-linux' to 'verification-done-jammy-linux'. If the problem still exists, change the tag 'verification-needed-jammy-linux' to 'verification-failed-jammy-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

I verified the issue on kernel linux/5.4.0-166.183, linux/5.15.0-88.98 and linux/6.2.0-36.37 and the issue is fixed. I was able to run enclave in debug mode in all 3 kernels.

[Daniel Arai (danielarai)]

So it looks like this patch was applied to linux/5.4.0-166.183, linux/5.15.0-88.98, and linux/6.2.0-36.37, but I'm not seeing a request for verification on the jammy-azure-5.15.0-1049 kernel series, and it looks like linux-azure (5.15.0-1049.56) does not include the fix. Can we get the azure kernel fixed as well?

If the problem is solved, change the tag 'verification-needed-focal-linux-nvidia-tegra-5.15' to 'verification-done-focal-linux-nvidia-tegra-5.15'. If the problem still exists, change the tag 'verification-needed-focal-linux-nvidia-tegra-5.15' to 'verification-failed-focal-linux-nvidia-tegra-5.15'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
