When sending QP1 MAD packets which use a GRH, the source GID (which consists of the 64-bit subnet prefix, and the 64 bit port GUID) must be included in the packet GRH. For SR-IOV, a GID cache is used, since the source GID needs to be the slave's source GID, and not the Hypervisor's GID. This cache also included a subnet_prefix. Unfortunately, the subnet_prefix field in the cache was never initialized (to the default subnet prefix 0xfe80::0). As a result, this field remained all zeroes. Therefore, when SR-IOV was active, all QP1 packets which included a GRH had a source GID subnet prefix of all-zeroes. However, the subnet-prefix should initially be 0xfe80::0 (the default subnet prefix). In addition, if OpenSM modifies a port's subnet prefix, the new subnet prefix must be used in the GRH when sending QP1 packets. To fix this we now initialize the subnet prefix in the SR-IOV GID cache to the default subnet prefix. We update the cached value if/when OpenSM modifies the port's subnet prefix. We take this cached value when sending QP1 packets when SR-IOV is active. Note that the value is stored as an atomic64. This eliminates any need for locking when the subnet prefix is being updated. Note also that we depend on the FW generating the "port management change" event for tracking subnet-prefix changes performed by OpenSM. If running early FW (before 2.9.4630), subnet prefix changes will not be tracked (but the default subnet prefix still will be stored in the cache; therefore users who do not modify the subnet prefix will not have a problem). IF there is a need for such tracking also for early FW, we will add that capability in a subsequent patch.

Because of an incorrect bit-masking done on the join state bits, when handling a join request we failed to detect a difference between the group join state and the request join state when joining as send only full member (0x8). This caused the MC join request not to be sent. This issue is relevant only when SRIOV is enabled and SM supports send only full member. This fix separates scope bits and join states bits a nibble each. Fixes: b9c5d6a6 ('IB/mlx4: Add multicast group (MCG) paravirtualization for SR-IOV') Signed-off-by:

This fix solves a race between light flush and on the fly joins. Light flush doesn't set the device to down and unset IPOIB_OPER_UP flag, this means that if while flushing we have a MC join in progress and the QP was attached to BC MGID we can have a mismatches when re-attaching a QP to the BC MGID. The light flush would set the broadcast group to NULL causing an on the fly join to rejoin and reattach to the BC MCG as well as adding the BC MGID to the multicast list. The flush process would later on remove the BC MGID and detach it from the QP. On the next flush the BC MGID is present in the multicast list but not found when trying to detach it because of the previous double attach and single detach.

The debugfs RCU trips many debug kernel warnings because of potential sleeps with an RCU read lock held. This includes both user copy calls and slab allocations throughout the file. This patch switches the RCU to use SRCU for file remove/access race protection. In one case, the SRCU is implicit in the use of the raw debugfs file object and just works. In the seq_file case, a wrapper around seq_read() and seq_lseek() is used to enforce the SRCU using the debugfs supplied functions debugfs_use_file_start() and debugfs_use_file_stop(). The sychronize_rcu() is deleted since the SRCU prevents the remove access race. The RCU locking is kept for qp_stats since the QP hash list is protected using the non-sleepable RCU. Reviewed-by:

The global variable n_krcvqs stores the sum of the number of kernel receive queues of VLs 0-7 which the user can pass to the driver through the module parameter array krcvqs which is of type unsigned integer. If the user passes large value(s) into krcvqs parameter array, it can cause an arithmetic overflow while calculating n_krcvqs which is also of type unsigned int. The overflow results in an incorrect value of n_krcvqs which can lead to kernel crash while loading the driver. Fix by changing the data type of n_krcvqs to unsigned long. This patch also changes the data type of other variables that get their values from n_krcvqs. Reviewed-by:

When trying to align the source pointer and there's a byte carry in an SGE copy, bytes are borrowed from the next quad-word X to complete the required quad-word copy. Then, the SGE length is reduced by the number of borrowed bytes. After this, if the remaining number of bytes from quad-word X (extra bytes) is greater than the new SGE length, the number of extra bytes needs to be updated to the new SGE length. Otherwise, when the SGE length gets updated again after the extra bytes are read to create the new byte carry, it goes negative, which then becomes a very large number as the SGE length is an unsigned integer. This causes SGE buffer to be over-read. Reviewed-by:

When a new CM connection is being requested, ipoib driver copies data from the path pointer in the CM/tx object, the path object might be invalid at the point and memory corruption will happened later when now the CM driver will try using that data. The next scenario demonstrates it: neigh_add_path --> ipoib_cm_create_tx --> queue_work (pointer to path is in the cm/tx struct) #while the work is still in the queue, #the port goes down and causes the ipoib_flush_paths: ipoib_flush_paths --> path_free --> kfree(path) #at this point the work scheduled starts. ipoib_cm_tx_start --> copy from the (invalid)path pointer: (memcpy(&pathrec, &p->path->pathrec, sizeof pathrec);) -> memory corruption. To fix that the driver now starts the CM/tx connection only if that specific path exists in the general paths database. This check is protected with the relevant locks, and uses the gid from the neigh member in the CM/tx object which is valid according to the ref count that was taken by the CM/tx.

When the low level driver exercises the hot unplug they would call rdma_cm cma_remove_one which would fire DEVICE_REMOVAL event to all cma consumers. Now, if consumer doesn't make sure they destroy all IB objects created on that IB device instance prior to finalizing all processing of DEVICE_REMOVAL callback, rdma_cm will let the lld to de-register with IB core and destroy the IB device instance. And if the consumer calls (say) ib_dereg_mr(), it will crash since that dev object is NULL. In the current implementation, iser-target just initiates the cleanup and returns from DEVICE_REMOVAL callback. This deferred work creates a race between iser-target cleaning IB objects(say MR) and lld destroying IB device instance. This patch includes the following fixes -> make sure that consumer frees all IB objects associated with device instance -> return non-zero from the callback to destroy the rdma_cm id Signed-off-by:Raju Rangoju <rajur@chelsio.com> Acked-by:

If port_guid is set with the default subnet_prefix, then we get a change event and run a port refresh, we don't update the port_guid. As a result, attempts to create a target device that uses the new subnet_prefix in the wwn will fail to find a match and be rejected by the ib_srpt driver. This makes it impossible to configure a port if it was initialized with a default subnet_prefix and later changed to any non-default subnet-prefix. Updating the port refresh task to always update the wwn based upon the current subnext_prefix solves this problem.

Due to this ib_poll_handler() assumes all events polled and avoids further iopoll scheduling. This patch adds logic to cxgb4 ib_req_notify_cq() handler to check if CQ is not empty and return accordingly. Based on the return value of ib_req_notify_cq() handler, ib_poll_handler() will schedule a run of iopoll handler. Signed-off-by:
