The send complete for RC QPs mismanages the ack count when the responder side is only in RTR. A QP in that state cannot send requests, but it can be the target for operations that elicit responses. Adjust the RC completion logic to correct the count maintenance by reflecting RECV_OK in a new state test. Reviewed-by:

Convert copy_sge and related SGE state functions to use boolean. For determining if QP is in user mode, add helper function in rdmavt_qp.h. This is used to determine if QP needs the last byte ordering. While here, change rvt_pd.user to a boolean. Reviewed-by:

The EFI variable that provides board ID is named by the PCI address of the device, which is published in upper-case, while the HFI1 driver reads the EFI variable in lower-case. This prevents returning the correct board id when queried through sysfs. Read EFI variables in upper-case if the lower-case read fails. Reviewed-by:

There are some memory allocation calls in hfi1_create_ctxtdata() that do not use the numa function parameter. This can cause cache lines to be filled over QPI. Reviewed-by:

Having per-CPU reference count for each MR prevents cache-line bouncing across the system. Thus, it prevents bottlenecks. Use per-CPU reference counts per MR. The per-CPU reference count for FMRs is used in atomic mode to allow accurate testing of the busy state. Other MR types run in per-CPU mode MR until they're freed. Reviewed-by:

Receive code paths use the QP's device and port number to access the struct hfi1_ibport. When an instance of struct hfi1_ctxtdata is present, it can be used to access struct hfi1_ibport through a pointer. This makes struct hfi1_ibport lookup time faster as an array doesn't have to be indexed and access fields in other cache-lines. Reviewed-by:

The resource specific wait locking missed correcting the lock for the notify_error_qp() calldown. The code is fixed to correctly use the iowait lock field to protect the head that is protected by that lock. Fixes: Commit 4e045572 ("IB/hfi1: Add unique txwait_lock for txreq events") Reviewed-by:

After extended testing, it was found that the previous PCIe Gen 3 recipe, which used adaptive CTLE with Preset 4, could cause an NMI/Surprise Link Down in about 1 in 100 to 1 in 1000 power cycles on some platforms. New EV data combined with extensive empirical data indicates that the new recipe should use static CTLE with Preset 6 for all integrated silicon SKUs.

In the event that the IRQ thread is extremely busy, the processing of an rcd wait list can be delayed by quite a bit until the IRQ thread completes its work. The QP reset reference count wait can then appear to be stuck, thus causing up a QP destroy to emit the hung task diagnostic. Fix by processing the qp wait list periodically from the thread. The interval is a multiple (currently 4) of the MAX_PKT_RECV. Also, reduce some of the excessive inlining. The guidelines are per packet is ok inline, otherwise the choice is based on likelyhood of execution. Reviewed-by:

The destination address in a listening rdma_id does not have an address family. Since address family in both sides of a connection must be the same in rdma_bind_addr() we set the address family of the destination to the address family of the source. This patch serves the logic in cma_port_is_unique() which requires to know if destination address that is associated with a rdma_id is any address (cma_zero_addr() and cma_loopback_addr()). This can happen when port reuse is checked for a port number that is being listened to. Fixes: 19b752a1 ("IB/cma: Allow port reuse for rdma_id") Signed-off-by:

Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

When sending packet to destination that was not resolved yet via path query, the driver keeps the skb and tries to re-send it again when the path is resolved. But when re-sending via dev_queue_xmit the kernel doesn't call to dev_hard_header, so IPoIB needs to keep 20 bytes in the skb and to put the destination address inside them. In that way the dev_start_xmit will have the correct destination, and the driver won't take the destination from the skb->data, while nothing exists there, which causes to packet be be dropped. The test flow is: 1. Run the SM on remote node, 2. Restart the driver. 4. Ping some destination, 3. Observe that first ICMP request will be dropped.

This patch introduces the RoCE driver for the Broadcom NetXtreme-E 10/25/40/50G RoCE HCAs. The RoCE driver is a two part driver that relies on the parent bnxt_en NIC driver to operate. The changes needed in the bnxt_en driver have already been incorporated via Dave Miller's net tree into the mainline kernel. The vendor official git repository for this driver is available on github as: https://github.com/Broadcom/linux-rdma-nxt/Signed-off-by:

If IPV6 has not been enabled in the underlying kernel, we must avoid calling IPV6 procedures in rdma_cm.ko. This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements surrounding any code which calls external IPV6 procedures. In the instance fixed here, procedure cma_bind_addr() called ipv6_addr_type() -- which resulted in calling external procedure __ipv6_addr_type().
