* IB/rxe: Set dma_mask and coherent_dma_maskyonatanc2017-07-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RXE coupled with dummy device causes to the kernel panic attached below. The panic happens when ib_register_device tries to set dma_mask by accessing a NULLed parent device. The RXE does not actually use DMA, so we can set the dma_mask to architecture value.

* IB/rxe: Fix kernel panic from skb destructorYonatan Cohen2017-07-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the time between rxe_send has finished and skb destructor called, the QP's ref count might be 0, leading to a possible QP destruction. This will lead to a kernel panic when the destructor dereferences the QP. The operation of incrementing QP ref count at rxe_send and decrementing from skb destructor will prevent this crash.

* IB/core: Add ordered workqueue for RoCE GID managementMajd Dibbiny2017-07-181-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs according to the netdev events. The ib_wq isn't an ordered workqueue and thus two work elements can be executed concurrently which will result in unexpected behavior and inconsistency of the GIDs cache content. Example: ifconfig eth1 11.11.11.11/16 up This command will invoke the following netdev events in the following order: 1. NETDEV_UP 2. NETDEV_DOWN 3. NETDEV_UP If (2) and (3) will be executed concurrently or in reverse order, instead of having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.

* IB/IPoIB: Convert IPoIB to memalloc_noio_* callsLeon Romanovsky2017-07-181-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | Commit 21caf2fc1931 ("mm: teach mm by current context info to not do I/O during memory allocation") added the memalloc_noio_(save|restore) functions to enable people to modify the MM behavior by disabling I/O during memory allocation. This was further extended in Fixes: 934f3072c17c ("mm: clear __GFP_FS when PF_MEMALLOC_NOIO is set"). memalloc_noio_* functions prevent allocation paths recursing back into the filesystem without explicitly changing the flags for every allocation site. However the IPoIB hasn't been keeping up with the changes and missed completely these memalloc_noio_* calls. This led to update of allocation site with special QP creation flag, see commit 09b93088d750 ("IB: Add a QP creation flag to use GFP_NOIO allocations"), while this flag is supported by small number of drivers in IB stack. Let's change it by updating to memalloc_noio_* calls and allow for every driver underneath enjoy NOIO allocations.

* IB/core: Don't resolve IP address to the loopback deviceMoni Shoua2017-07-173-45/+32
| | | | | | | | | | | | | | | | | | | | When resolving an IP address that is on the host of the caller the result from querying the routing table is the loopback device. This is not a valid response, because it doesn't represent the RDMA device and the port. Therefore, callers need to check the resolved device and if it is a loopback device find an alternative way to resolve it. To avoid this we make sure that the response from rdma_resolve_ip() will not be the loopback device. While that, we fix an static checker warning about dereferencing an unintitialized pointer using the same solution as in commit abeffce90c7f ("net/mlx5e: Fix a -Wmaybe-uninitialized warning") as a reference.

Answer: Yes. ib_init_ah_from_wc() creates ah from the incoming packet. Incoming packet has dgid of the receiver node on which this code is getting executed and sgid contains the GID of the sender. When resolving mac address of destination, you use arrived dgid as sgid and use sgid as dgid because sgid contains destinations GID whom to respond to. Signed-off-by: Gustavo A. R.
