------- Comment From stefan.ra...@de.ibm.com 2020-06-04 10:10 EDT------- Note: This patch is currently not upstream. It will be part of the full SMC-D v2 implementation (see LP1853291), and was successfully tested with a reference implementation. However, we still have some way to go with our SMC-D v2 code, yet other providers of SMC-D v2 implementations asked us to ship this toleration patch early, so that users have a chance to have their systems up to date by the time they deliver their versions.

Problem: Later-level versions of SMC present, although backwards- compatible, a higher version number, and use larger messages during the CLC handshake. Solution: Adjust for tolerating later version numbers, and support CLC messages of arbitrary length. Reproduction: Enable a server on Linux for SMC, and connect using a later- level version of SMC Applicable for: Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1882088/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
