From cbed10970409643e38b6d0e52de3758629f6c2e1 Mon Sep 17 00:00:00 2001 From: Tatyana Nikolova Date: Fri, 8 May 2015 16:36:33 -0500 Subject: [PATCH] RDMA/core: Fix for parsing netlink string attribute [ Upstream commit ec04847c0c5b471bab2dacceadfdb803a9d1a2ea ] The string iwpm_ulib_name is recorded in a nlmsg as a netlink attribute. Without this fix parsing of the nlmsg by the userspace port mapper service fails because of unknown attribute length, causing the port mapper service not to register the client, which has sent the nlmsg.
