From 2e3cbdeae8e4d13087657d95ed7a5be57dc9695e Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Fri, 4 Jan 2013 00:32:54 +0000 Subject: rtnetlink: Compute and store minimum ifinfo dump size commit c7ac8679bec9397afe8918f788cbcef88c38da54 upstream. The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request.
