The currently include file ordering for rdmavt headers has an ab/ba include issue the precludes using inlines from rdma_vt.h in rdmavt_qp.h. At the heart of the issue is that rdma_vt.h includes rdmavt_qp.h. Fix the ordering issue by adjusting rdma_vt.h to not require rdmavt_qp.h and move qp related inlines to rdmavt_qp.h. Additionally, promote rvt_mmap_info to rdma_vt.h since it is shared by rdmavt_cq.h and rdmavt_qp.h. Reviewed-by:

Some kernels now enable CONFIG_IO_STRICT_DEVMEM which prevents multiple handles to PCI resource0. In order to continue to support expansion ROM updates while the driver is loaded, the driver must now provide an interface to control the expansion ROM write protection. This patch adds an exprom_wp debugfs interface that allows the hfi1_eprom user tool to disable the expansion ROM write protection by opening the file and writing a '1'. The write protection is released when writing a '0' or automatically re-enabled when the file handle is closed. The current implementation will only allow one handle to be opened at a time across all hfi1 devices. Reviewed-by:

Verbs destroy callbacks are synchronous operations and can't be delayed. The expectation is that after driver returned from destroy function, the memory can be freed and user won't be able to access it again. Ditch workqueue implementation used in HNS driver.

When two netdev have same link local addresses (such as vlan and non vlan), two rdma cm listen id should be able to bind to following different addresses. listener-1: addr=lla, scope_id=A, port=X listener-2: addr=lla, scope_id=B, port=X However while comparing the addresses only addr and port are considered, due to which 2nd listener fails to listen. In below example of two listeners, 2nd listener is failing with address in use error. $ rping -sv -a fe80::268a:7ff:feb3:d113%ens2f1 -p 4545& $ rping -sv -a fe80::268a:7ff:feb3:d113%ens2f1.200 -p 4545 rdma_bind_addr: Address already in use To overcome this, consider the scope_ids as well which forms the accurate IPv6 link local address.

IPv6 link local address for a VLAN netdevice has nothing to do with its resemblance with the default GID, because VLAN link local GID is in different layer 2 domain. Now that RoCE MAD packet processing and route resolution consider the right GID index, there is no need for an unnecessary check which prevents the addition of vlan based IPv6 link local GIDs.

Switchdev mode and mutiport RoCE mode aren't compatible at this point. Don't create IB reps when a user switches to switchdev mode and the driver operates in that mode. Signed-off-by:

When working in mutliport RoCE mode it is possible to attach a slave before the master. In that case the slave is waiting for a master to be attached. When the master is attached it goes over the list of waiting slaves, finds a slave that is compatible and tries to bind it to itself. The call stack is: mlx5_ib_init_multiport_master() -> mlx5_ib_bind_slave_port() In the bind function we will create a netdev notifier, but this is done before we initialize the RoCE structure (this is done at a later stage by the master in the ROCE stage). Once events are delivered to that notifier we will use mlx5_ib_get_native_port_mdev() to get the actual port and as the native port is zero we will access an invalid index in the port structure. Move the RoCE structure initialization to an earlier stage. Fixes: 32f69e4b ("{net, IB}/mlx5: Manage port association for multiport RoCE") Signed-off-by:

Allow this only via mlx5 raw create flow API, legacy verbs are not supported. To accommodate that, we add a new attribute to matcher creation to indicate the type of flow table to be used. MLX5_IB_ATTR_FLOW_MATCHER_FT_TYPE With this new attribute MLX5_IB_ATTR_FLOW_MATCHER_FLOW_FLAGS is no longer needed, we keep it for compatibility but at most only a single attribute can be passed of the two. When inserting a flow rule to the FDB we require that a DEVX FT is provided as a destination, no other configuration is allowed. Signed-off-by:

Provide an option to change the net namespace of a rdma device through a netlink command. When multiple rdma devices exists in a system, and when containers are used, this will limit rdma device visibility to a specified net namespace. An example command to change net namespace of mlx5_1 device to the previously created net namespace 'foo' is: $ ip netns add foo $ rdma dev set mlx5_1 netns foo Signed-off-by:

Introduce a helper function that changes rdma device's net namespace which performs mini disable/enable sequence to have device visible only in assigned net namespace. Device unregistration, device rename and device change net namespace may be invoked concurrently. (a) device unregistration needs to wait if a device change (rename or net namespace change) operation is in progress. (b) device net namespace change should not proceed if the unregistration has started. (c) while one cpu is changing device net namespace, other cpu should not be able to rename or change net namespace. To address above concurrency, (a) Use unreg_mutex to synchronize between ib_unregister_device() and net namespace change operation (b) In cases where unregister_device() has started unregistration before change_netns got chance to acquire unreg_mutex, validate the refcount - if it dropped to zero, abort the net namespace change operation. Finally use the helper function to change net namespace of ib device to move the device back to init_net when such net is deleted. Signed-off-by: -
