  "message": "RDMA/ocrdma: Dont use PD 0 for userpace CQ DB\n\nCreate_CQ verb doesn\u0027t provide a PD pointer.  So, until now we are\ncreating all (both userspace and kernel) CQ DB regions from PD0.  This\nwill result in mmapping PD0 to applications.  A rogue userspace\napplication can mess things up.\n\nAlso more serious issues is even the be2net NIC uses PD0.\n\nThis patch addresses this problem by:\n\n1) Create a PD page for every userspace application when the\n   alloc_ucontext is called. This will be destroyed in\n   dealloc_ucontext.\n2) All CQs for that context will use the PD allocated in ucontext.\n3) The first create_PD call from application will result in returning\n   the PD address from its ucontext (no new PD will be created).\n4) For subsecquent create_pd calls from application, we create new PDs for\n   the application.\n\nSigned-off-by: Naresh Gottumukkala \u003cbgottumukkala@emulex.com\u003e\nSigned-off-by: Roland Dreier \u003croland@purestorage.com\u003e\n",
