2015-08-30IB/iser: Unify fast memory registration flowsSagi Grimberg3-131/+113
iser_reg_rdma_mem_[fastreg|fmr] share a lot of code, and logically do the same thing other than the buffer registration method itself (iser_fast_reg_mr vs. iser_fast_reg_fmr). The DIF logic is not implemented in the FMR flow as there is no existing device that supports FMRs and Signature feature. This patch unifies the flow in a single routine iser_reg_rdma_mem and just split to fmr/frwr for the buffer registration itself. Also, for symmetry reasons, unify iser_unreg_rdma_mem (which will call the relevant device specific unreg routine).

2015-08-30IB/iser: Maintain connection fmr_pool under a single registration descriptorAdir Lev3-54/+68
This will allow us to unify the memory registration code path between the various methods which vary by the device capabilities. This change will make it easier and less intrusive to remove fmr_pools from the code when we'd want to. The reason we use a single descriptor is to avoid taking a redundant spinlock when working with FMRs. We also change the signature of iser_reg_page_vec to make it match iser_fast_reg_mr (and the future indirect registration method).

This is not the case anymore and if we tried to allocate an fmr_pool then it is supported and we expect to succeed.

2015-08-30IB/iser: Introduce struct iser_reg_resourcesSagi Grimberg3-81/+91
Have fast_reg_descriptor hold struct iser_reg_resources (mr, frpl, valid flag). This will be useful when the actual buffer registration routines will be passed with the needed registration resources (i.e. iser_reg_resources) without being aware of their nature (i.e. data or protection). In order to achieve this, we remove reg_indicators flags container and place specific flags (mr_valid) within iser_reg_resources struct. We also place the sig_mr_valid and sig_protcted flags in iser_pi_context. This patch also modifies iser_fast_reg_mr to receive the reg_resources instead of the fast_reg_descriptor and a data/protection indicator.

This patch routes a SA pathrecord query to netlink first and processes the response appropriately. If a failure is returned, the request will be sent through IB. The decision whether to route the request to netlink first is determined by the presence of a listener for the local service netlink multicast group.

2015-08-30IB/mlx4: Fix incorrect cq flushing in error stateAriel Nahum1-1/+1
When handling a device internal error, the driver is responsible to drain the completion queue with flush errors. In case a completion queue was assigned to multiple send queues, the driver iterates over the send queues and generates flush errors of inflight wqes. The driver must correctly pass the wc array with an offset as a result of the previous send queue iteration. Not doing so will overwrite previously set completions and return a wrong number of polled completions which includes ones which were not correctly set.

2015-08-30IB/core: Add RoCE table bonding supportMatan Barak1-20/+285
Handling bonding and other devices require us to all all GIDs of the net-devices which are upper-devices of the RoCE port related net-device. Active-backup configurations imposes even more challenges as the default GID should only be set on the active devices (this is necessary as otherwise the same MAC could be used for several slaves and thus several slaves will have identical GIDs). Managing these configurations are done by listening to: (a) NETDEV_CHANGEUPPER event (1) if a related net-device is linked, delete all inactive slaves default GIDs and add the upper device GIDs. (2) if a related net-device is unlinked, delete all upper GIDs and add the default GIDs. (b) NETDEV_BONDING_FAILOVER: (1) delete the bond GIDs from inactive slaves (2) delete the inactive slave's default GIDs (3) Add the bond GIDs to the active slave.

2015-08-30IB/core: Add RoCE GID table managementMatan Barak5-106/+1274
RoCE GIDs are based on IP addresses configured on Ethernet net-devices which relate to the RDMA (RoCE) device port. Currently, each of the low-level drivers that support RoCE (ocrdma, mlx4) manages its own RoCE port GID table. As there's nothing which is essentially vendor specific, we generalize that, and enhance the RDMA core GID cache to do this job. In order to populate the GID table, we listen for events: (a) netdev up/down/change_addr events - if a netdev is built onto our RoCE device, we need to add/delete its IPs. This involves adding all GIDs related to this ndev, add default GIDs, etc. (b) inet events - add new GIDs (according to the IP addresses) to the table. For programming the port RoCE GID table, providers must implement the add_gid and del_gid callbacks. RoCE GID management requires us to state the associated net_device alongside the GID. This information is necessary in order to manage the GID table. For example, when a net_device is removed, its associated GIDs need to be removed as well. RoCE mandates generating a default GID for each port, based on the related net-device's IPv6 link local. In contrast to the GID based on the regular IPv6 link-local (as we generate GID per IP address), the default GID is also available when the net device is down (in order to support loopback). Locking is done as follows: The patch modify the GID table code both for new RoCE drivers implementing the add_gid/del_gid callbacks and for current RoCE and IB drivers that do not. The flows for updating the table are different, so the locking requirements are too. While updating RoCE GID table, protection against multiple writers is achieved via mutex_lock(&table->lock). Since writing to a table requires us to find an entry (possible a free entry) in the table and then modify it, this mutex protects both the find_gid and write_gid ensuring the atomicity of the action. Each entry in the GID cache is protected by rwlock. In RoCE, writing (usually results from netdev notifier) involves invoking the vendor's add_gid and del_gid callbacks, which could sleep. Therefore, an invalid flag is added for each entry. Updates for RoCE are done via a workqueue, thus sleeping is permitted. In IB, updates are done in write_lock_irq(&device->cache.lock), thus write_gid isn't allowed to sleep and add_gid/del_gid are not called. When passing net-device into/out-of the GID cache, the device is always passed held (dev_hold). The code uses a single work item for updating all RDMA devices, following a netdev or inet notifier. The patch moves the cache from being a client (which was incorrect, as the cache is part of the IB infrastructure) to being explicitly initialized/freed when a device is registered/removed.
