Raju Rangoju f63ee3bb14 nvmet-rdma: fix null dereference under heavy load ... commit 5cbab6303b upstream. Under heavy load if we don't have any pre-allocated rsps left, we dynamically allocate a rsp, but we are not actually allocating memory for nvme_completion (rsp->req.rsp). In such a case, accessing pointer fields (req->rsp->status) in nvmet_req_init() will result in crash. To fix this, allocate the memory for nvme_completion by calling nvmet_rdma_alloc_rsp() Fixes: 8407879c("nvmet-rdma:fix possible bogus dereference under heavy load") Cc: <stable@vger.kernel.org> Reviewed-by: Max Gurtovoy <maxg@mellanox.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Raju Rangoju <rajur@chelsio.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Jens Axboe <axboe@kernel.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2019-01-31 08:12:37 +01:00
