* RDMA/cma: Add IPv6 support for iWARPSteve Wise2013-08-121-14/+32
| | | | | | | | | | | | | | | | | | Modify the type of local_addr and remote_addr fields in struct iw_cm_id from struct sockaddr_in to struct sockaddr_storage to hold IPv6 and IPv4 addresses uniformly. Change the references of local_addr and remote_addr in cxgb4, cxgb3, nes and amso drivers to match this. However to be able to actully run traffic over IPv6, low-level drivers have to add code to support this.

| * IB/core: Add "type 2" memory windows supportShani Michaeli2013-02-212-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enhances the IB core support for Memory Windows (MWs). MWs allow an application to have better/flexible control over remote access to memory. Two types of MWs are supported, with the second type having two flavors: Type 1 - associated with PD only Type 2A - associated with QPN only Type 2B - associated with PD and QPN Applications can allocate a MW once, and then repeatedly bind the MW to different ranges in MRs that are associated to the same PD. Type 1 windows are bound through a verb, while type 2 windows are bound by posting a work request. The 32-bit memory key is composed of a 24-bit index and an 8-bit key. The key is changed with each bind, thus allowing more control over the peer's use of the memory key. The changes introduced are the following: * add memory window type enum and a corresponding parameter to ib_alloc_mw. * type 2 memory window bind work request support. * create a struct that contains the common part of the bind verb struct ibv_mw_bind and the bind work request into a single struct. * add the ib_inc_rkey helper function to advance the tag part of an rkey. Consumer interface details: * new device capability flags IB_DEVICE_MEM_WINDOW_TYPE_2A and IB_DEVICE_MEM_WINDOW_TYPE_2B are added to indicate device support for these features. Devices can set either IB_DEVICE_MEM_WINDOW_TYPE_2A or IB_DEVICE_MEM_WINDOW_TYPE_2B if it supports type 2A or type 2B memory windows. It can set neither to indicate it doesn't support type 2 windows at all. * modify existing provides and consumers code to the new param of ib_alloc_mw and the ib_mw_bind_info structure Signed-off-by: Haggai Eran <haggaie@mellanox.com> Signed-off-by: Shani Michaeli <shanim@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

|/ | | | | | | | | | | | | Sure, it's just the pointer value we use, but the coverity checker complains about a use-after-free bug and it really does seem cleaner to delay freeing until we are entirely done with the memory. So, rearrange the code to move the kfree() later untill we are completely done. Trivial and harmless, but nice IMHO.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iw_cxgb3 has a potential problem where a CQ's comp_handler can get called simultaneously from different places in iw_cxgb3 driver. This does not comply with Documentation/infiniband/core_locking.txt, which states that at a given point of time, there should be only one callback per CQ should be active. Such problem was reported by Parav Pandit <Parav.Pandit@Emulex.Com> for iw_cxgb4 driver. Based on discussion between Parav Pandit and Steve Wise, this patch fixes the above problem by serializing the calls to a CQ's comp_handler using a spin_lock.

The result is the oops above, when t3_l2t_get attempts to dereference L2DATA(cdev)->nentries in arp_hash right after the EEH error handler sets it to NULL. The fix is to prevent the setting of the NULL pointer until after there are no further users of it. The t3cdev->l2opt pointer is now converted to be an rcu pointer and the L2DATA macro is now called under the protection of the rcu_read_lock(). When the EEH error path: t3_adapter_error->offload_close->cxgb3_offload_deactivate Is exectured, setting of that l2opt pointer to NULL, is now gated on an rcu quiescence point, preventing, allowing L2DATA callers to safely check for a NULL pointer without concern that the underlying data will be freeded before the pointer is dereferenced.

| | * RDMA/cxgb3: When a user QP is marked in error, also mark the CQs in errorSteve Wise2010-10-236-20/+71
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The flushing of work requests for user QPs is implemented entirely in the user mode library. The only kernel interaction is to mark the user QP object indicating it is in error when the QP exits RTS. When the user QP operations are called by the application (eg: post_send, post_recv), the QP in error bit is checked and if set, the library flushes the QP. If, however, the application is not doing IO, but rather just polling the CQ, it will never get flushed work requests. This breaks some classes of applications. This patch adds logic to mark user CQs in error when a QP that is bound to the CQ is marked in error. The library poll code can then notice the CQ is in error and flush all the in error QPs bound to that CQ. Design: - add 1 extra CQE entry to the CQ memory that will be used to indicate in error status. - return the desired CQ memory size that should be mapped by the library - bump the ABI since the create_cq uverbs response changes. - detect older libraries and reduce the mmap size accordingly. (The ABI bump doesn't break old libraries, since they didn't check the ABI field anyway) Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* | RDMA/cxgb3: Turn off RX coalescing for iWARP connectionsSteve Wise2010-09-271-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The HW by default has RX coalescing on. For iWARP connections, this causes a 100ms delay in connection establishement due to the ingress MPA Start message being stalled in HW. So explicitly turn RX coalescing off when setting up iWARP connections. This was causing very bad performance for NP64 gather operations using Open MPI, due to the way it sets up connections on larger jobs.
