------- Comment From ifran...@de.ibm.com 2018-10-04 06:45 EDT------- This fix is almost impossible to verify on a running system, the problem has just been identified by code inspection. So fix verification can only be done based on the source code. I assume that the patch has applied correctly, otherwise you would have reported that, so I am setting the tag to 'verification-done-bionic'.

Status in Ubuntu on IBM z Systems: Fix Committed Status in linux package in Ubuntu: Fix Committed Status in linux source package in Bionic: Fix Committed Status in linux source package in Cosmic: Fix Committed Bug description: SRU Justification Impact: An incorrect return value check can result in a protected key not being re-transformed when it became invalid. Fix: Upstream commit b81126e01a8c6048249955feea46c8217ebefa91. Regression Potential: This is a trivial patch to an architecture- specific driver, so there is minimal potential for regression. --- Description: s390/crypto: Fix return code checking in cbc_paes_crypt. Symptom: A protected key is not re-transformed when it became invalid Problem: The return code of cpacf_kmc() is less than the number of bytes to process in case of an error, not greater. Solution: Correct return code checking.
