There are 2 ways to create IPoIB PKEY child interfaces: 1) Writing a PKEY to /sys/class/net/<ib parent interface>/create_child. 2) Using netlink with iproute. While with sysfs the child interface has the same number of tx and rx queues as the parent, with netlink there will always be 1 tx and 1 rx queue for the child interface. That's because the get_num_tx/rx_queues() netlink ops are missing and the default value of 1 is taken for the number of queues (in rtnl_create_link()). This change adds the get_num_tx/rx_queues() ops which allows for interfaces with multiple queues to be created over netlink. This constant only represents the max number of tx and rx queues on that net device. Fixes: 9baa0b03 ("IB/ipoib: Add rtnl_link_ops support") Signed-off-by:

Similar to RDMA and Atomic qp attributes enabled by default in CM, enable FLUSH attribute for supported device. That makes applications that are built with rdma_create_ep, rdma_accept APIs have FLUSH qp attribute natively so that user is able to request FLUSH operation simpler. Note that, a FLUSH operation requires FLUSH are supported by both device(HCA) and memory region(MR) and QP at the same time, so it's safe to enable FLUSH qp attribute by default here. FLUSH attribute can be disable by modify_qp() interface. Link: https://lore.kernel.org/r/20221206130201.30986-10-lizhijian@fujitsu.com Signed-off-by:

The code in rxe_resp.c at check_length() is incorrect as it compares pkt->opcode an 8 bit value against various mask bits which are all higher than 256 so nothing is ever reported. This patch rewrites this to compare against pkt->mask which is correct. However this now exposes another error. For UD send packets the value of the pmtu cannot be determined from qp->mtu. All that is required here is to later check if the payload fits into the posted receive buffer in that case.

After the hns roce driver is loaded, if you modify the mac address of the network port, the following error will appear: __ib_cache_gid_add: unable to add gid fe80:0000:0000:0000:4600:4dff:fe22:abb5 error=-28 hns3 0000:7d:00.0 hns_0: attr path_mtu(1) invalid while modify qp The reason for the error is that the gid being occupied will cause the failure to modify the gid. The gid is occupied by the loopback QP used by free mr. When the mac address is modified, the gid will change. If there is a busy QP at this time, the gid will not be released and the modification will fail. The QP of free mr is created using the ib interface. The ib interface will add a reference count to the gid, resulting in this error scenario. Considering that free mr is solving a bug in HIP08, not an actual business, it is not necessary to use ib interfaces.

The ack timeout retransmission time is affected by the following two factors: one is packet life time, another is the HCA processing time. Now the default packet lifetime(CMA_IBOE_PACKET_LIFETIME) is 18. That means the minimum ack timeout is 2 seconds (2^(18+1)*4us=2.097seconds). The packet lifetime means the maximum transmission time of packets on the network, 2 seconds is too long. Assume the network is a clos topology with three layers, every packet will pass through five hops of switches. Assume the buffer of every switch is 128MB and the port transmission rate is 25 Gbit/s, the maximum transmission time of the packet is 200ms(128MB*5/25Gbit/s). Add double redundancy, it is less than 500ms. So change the CMA_IBOE_PACKET_LIFETIME to 16, the maximum transmission time of the packet will be about 500+ms, it is long enough.

Goto label 'free' where it will kfree the 'in' is not needed though it's safe to kfree NULL. Return err code directly to simplify the code. 1973 free: 1974 kfree(in); 1975 return err; Signed-off-by:

In the previous iteration of the while loop, the "ret" may have been assigned a value of 0, so the error return code -EINVAL may have been incorrectly set to 0. To fix set valid return code before calling to goto. Also investigate each case separately as Andy suggessted. Fixes: e711f968 ("IB/srp: replace custom implementation of hex2bin()") Fixes: 2a174df0 ("IB/srp: Use kstrtoull() instead of simple_strtoull()") Fixes: 19f31343 ("IB/srp: Add RDMA/CM support") Signed-off-by:

Disable all of drivers/infiniband/hw/ and rdmavt for UML builds until someone needs it and provides patches to support it. This prevents build errors in hw/qib/qib_wc_x86_64.c. Fixes: 68f5d3f3 ("um: add PCI over virtio emulation driver") Signed-off-by:

Pull dax fixes from Dan Williams: "A few bug fixes around the handling of "Soft Reserved" memory and memory tiering information. Linux is starting to enounter more real world systems that deploy an ACPI HMAT to describe different performance classes of memory, as well the "special purpose" (Linux "Soft Reserved") designation from EFI. These fixes result from that testing. It has all appeared in -next for a while with no known issues. - Fix duplicate overlapping device-dax instances for HMAT described "Soft Reserved" Memory - Fix missing node targets in the sysfs representation of memory tiers - Remove a confusing variable initialization" * tag 'dax-fixes-6.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: Fix duplicate 'hmem' device registration ACPI: HMAT: Fix initiator registration for single-initiator systems ACPI: HMAT: remove unnecessary variable initialization

The Intel fix looks like the most important. - Fix a potential divide by zero in pinctrl-singe (OMAP and HiSilicon) - Disable IRQs on startup in the Mediatek driver.
