This bug is awaiting verification that the 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- artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed- artful'.
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.

Commit e666d4e9ceec fixes this problem by using a new structure for the generic ciphers. This commit is also needed in Bionic until it gets rebased to 4.15. Commit e666d4e9ceec was added to mainline in v4.15-rc2 == Fix == commit e666d4e9ceec94c0a88c94b7db31d56474da43b3 Author: Paulo Flabiano Smorigo <[email protected]> Date: Mon Oct 16 20:54:19 2017 -0200 crypto: vmx - Use skcipher for ctr fallback == Regression Potential == This commit is specific to crypto, and adds a new structure for the generic ciphers. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug. == Original Bug Desription: == == Comment: #0 - Paulo Flabiano Smorigo <[email protected]> - 2017-11-17 10:29:14 == Ubuntu 17.10 uses linux kernel 4.13 witch has a problem with the fallback cipher for CTR mode. The commit bellow fixes this problem by using the new structure for the generic ciphers. Please add it to the kernel package. https://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6.git/commit/?id=e666d4e9ceec94c0a88c94b7db31d56474da43b3 == Comment: #1 - VIPIN K.
