From 7a8690ed6f5346f6738971892205e91d39b6b901 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Wed, 23 May 2018 08:22:11 +0300 Subject: RDMA/ucm: Mark UCM interface as BROKEN In commit 357d23c811a7 ("Remove the obsolete libibcm library") in rdma-core [1], we removed obsolete library which used the /dev/infiniband/ucmX interface. Following multiple syzkaller reports about non-sanitized user input in the UCMA module, the short audit reveals the same issues in UCM module too. It is better to disable this interface in the kernel, before syzkaller team invests time and energy to harden this unused interface.
