An updated hwdata package that fixes two bugs is now available for Red HatEnterprise Linux 7.

The hwdata package contains files with hardware identification and configurationdata.This update fixes the following bugs:* The current hardware-accelerated implementation of the aes_ctr cipher in thenx_crypto module does not work on the big-endian variants of IBM POWER8machines. As a consequence, the Encapsulating Security Payload (ESP) InternetProtocol Security (IPsec) protocol previously failed when used on IBM PowerSystems. This update blacklists nx_crypto on IBM Power Systems, and, as aresult, ESP IPsec works as expected on the big-endian variant of IBM POWER8.Note that users running any IBM Power Systems other than the big-endian variantof IBM POWER8 can safely comment out the “blacklist nx_crypto” line in the/usr/lib/modprobe.d/dist-blacklist.conf file. (BZ#1211641)* The newly added secure hash algorithm (SHA) multi-buffer kernel module,sha1-mb, has been blacklisted to prevent it from negatively impacting systemperformance. Users who require the sha1-mb module now have to comment out the”blacklist sha1-mb” line in the /usr/lib/modprobe.d/dist-blacklist.conf file.(BZ#1210652)Users of hwdata are advised to upgrade to this updated package, which fixesthese bugs.
Before applying this update, make sure all previously released errata relevantto your system have been applied.For details on how to apply this update, refer to:https://access.redhat.com/articles/11258Red Hat Enterprise Linux Desktop (v. 7)
