It might provide user with invalid data after uncompression. So the fix is add CRC support - means Linux adds CRC flag before calling the nx842 so that CRC will be added and checked during compression and uncompression calls. Contact Information = hb...@us.ibm.com ---uname output--- Ubuntu 15.10 Machine Type = power8 ---Debugger--- A debugger is not configured ---Steps to Reproduce--- HW team reported this issue and discussed with them for the possible solution. Stack trace output: no Oops output: no System Dump Info: The system is not configured to capture a system dump. *Additional Instructions for hb...@us.ibm.com: -Attach sysctl -a output output to the bug. == Comment: #1 - Haren Myneni <hb...@us.ibm.com> - 2015-09-19 20:36:14 == The fix is simple with just adding CRC flags before invoking nx842 coprocessor calls. Posted patch and waiting for maintainer to get in to his tree. http://marc.info/?l=linux-crypto-vger&m=144270742211554&w=2 Please include this fix in ubuntu 15.10 release.
