Playing with IP-O-IB interface can trigger a warning message: "ib0: Failed to modify QP to ERROR state" to be logged. This happens when the QP is in IB_QPS_RESET state and the stack is trying to transition it to IB_QPS_ERR state in ipoib_ib_dev_stop(). According to the IB spec, Table 91 - "QP State Transition Properties" it looks like the transition from reset to error is valid: Transition: Any State to Error Required Attributes: None Optional Attributes: None allowed Actions: Queue processing is stopped. Work Requests pending or in process are completed in error, when possible. This patch allows the transition and quiets the message. Reviewed-by:

In hip06 SoC, RoCE driver creates 8 reserved loopback QPs to ensure zero wqe when free mr. However, if the enabled phy port number is less than 6, it will fail in polling cqe with 8 reserved loopback QPs. In order to solve this problem, the number of loopback Qps will be adjusted based on the number of enabled phy port. Signed-off-by:

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.

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.

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. Signed-off-by:

Commit 21caf2fc ("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: 934f3072 ("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 09b93088 ("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. Signed-off-by:

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 abeffce9 ("net/mlx5e: Fix a -Wmaybe-uninitialized warning") as a reference.

While looking into Coverity ID 1351047 I ran into the following piece of code at drivers/infiniband/core/verbs.c:496: ret = rdma_addr_find_l2_eth_by_grh(&dgid, &sgid, ah_attr->dmac, wc->wc_flags & IB_WC_WITH_VLAN ? NULL : &vlan_id, &if_index, &hoplimit); The issue here is that the position of arguments in the call to rdma_addr_find_l2_eth_by_grh() function do not match the order of the parameters: &dgid is passed to sgid &sgid is passed to dgid This is the function prototype: int rdma_addr_find_l2_eth_by_grh(const union ib_gid *sgid, const union ib_gid *dgid, u8 *dmac, u16 *vlan_id, int *if_index, int *hoplimit) My question here is if this is intentional? 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:

Several variables had their types changed from unsigned long to u32, but the arch-specific implementations of flat_set_persistent() weren't updated, leading to compiler warnings on blackfin and m68k: fs/binfmt_flat.c: In function ‘load_flat_file’: fs/binfmt_flat.c:799: warning: passing argument 2 of ‘flat_set_persistent’ from incompatible pointer type Fixes: 468138d7 ("binfmt_flat: flat_{get,put}_addr_from_rp() should be able to fail") Signed-off-by: -
