* Make mlx5_cmd_exec_cb() a safe API in mlx5core.Hans Petter Selasky2020-11-162-4/+10
| | | | | | | | | | | | | | | | | | | | APIs that have deferred callbacks should have some kind of cleanup function that callers can use to fence the callbacks. Otherwise things like module unloading can lead to dangling function pointers, or worse. The IB MR code is the only place that calls this function and had a really poor attempt at creating this fence. Provide a good version in the core code as future patches will add more places that need this fence.

* Infiniband clients must be attached and detached in a specific order in ibcore.Hans Petter Selasky2020-07-061-2/+2
| | | | | | | | | | | | | | | | | | | Currently the linking order of the infiniband, IB, modules decide in which order the clients are attached and detached. For example one IB client may use resources from another IB client. This can lead to a potential deadlock at shutdown. For example if the ipoib is unregistered after the ib_multicast client is detached, then if ipoib is using multicast addresses a deadlock may happen, because ib_multicast will wait for all its resources to be freed before returning from the remove method. Fix this by using module_xxx_order() instead of module_xxx().

* Add support for prio-tagged traffic for RDMA in ibcore.Hans Petter Selasky2018-07-171-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | When receiving a PCP change all GID entries are reloaded. This ensures the relevant GID entries use prio tagging, by setting VLAN present and VLAN ID to zero. The priority for prio tagged traffic is set using the regular rdma_set_service_type() function. Fake the real network device to have a VLAN ID of zero when prio tagging is enabled. This is logic is hidden inside the rdma_vlan_dev_vlan_id() function which must always be used to retrieve the VLAN ID throughout all of ibcore and the infiniband network drivers. The VLAN presence information then propagates through all of ibcore and so incoming connections will have the VLAN bit set. The incoming VLAN ID is then checked against the return value of rdma_vlan_dev_vlan_id(). MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=336372

* Set correct SL in completion for RoCE in mlx5ib(4).Hans Petter Selasky2018-03-081-3/+16
| | | | | | | | | | | | | | | | | | | | There is a difference when parsing a completion entry between Ethernet and IB ports. When link layer is Ethernet the bits describe the type of L3 header in the packet. In the case when link layer is Ethernet and VLAN header is present the value of SL is equal to the 3 UP bits in the VLAN header. If VLAN header is not present then the SL is undefined and consumer of the completion should check if IB_WC_WITH_VLAN is set. While that, this patch also fills the vlan_id field in the completion if present. linux commit 12f8fedef2ec94c783f929126b20440a01512c14 MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=330662

* Optimize ibcore RoCE address handle creation from user-space.Hans Petter Selasky2018-03-053-3/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creating a UD address handle from user-space or from the kernel-space, when the link layer is ethernet, requires resolving the remote L3 address into a L2 address. Doing this from the kernel is easy because the required ARP(IPv4) and ND6(IPv6) address resolving APIs are readily available. In userspace such an interface does not exist and kernel help is required. It should be noted that in an IP-based GID environment, the GID itself does not contain all the information needed to resolve the destination IP address. For example information like VLAN ID and SCOPE ID, is not part of the GID and must be fetched from the GID attributes. Therefore a source GID should always be referred to as a GID index. Instead of going through various racy steps to obtain information about the GID attributes from user-space, this is now all done by the kernel. This patch optimises the L3 to L2 address resolving using the existing create address handle uverbs interface, retrieving back the L2 address as an additional user-space information structure. This commit combines the following Linux upstream commits: IB/core: Let create_ah return extended response to user IB/core: Change ib_resolve_eth_dmac to use it in create AH IB/mlx5: Make create/destroy_ah available to userspace IB/mlx5: Use kernel driver to help userspace create ah IB/mlx5: Report that device has udata response in create_ah MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=330508
