* ofed: reduce usage of struct dma_attrs *dma_attrsBjoern A. Zeeb2026-02-241-4/+4
| | | | | | | | | | | | | | | | | | | | | | | ib_verbs.h still uses struct dma_attrs *dma_attrs everywhere. It is beyond my knowledge when that struct got deprecated upstream but it is still supported by our LinuxKPI. The problem is that the functions called with that argument (dma_map_single_attrs, dma_unmap_single_attrs, dma_map_sg_attrs, dma_unmap_sg_attrs) so far are #defines in LinuxKPI and drop the last argument (attrs) so it was never a problem. In preparation to pass the attrs to the actual implementation in LinuxKPI, which has gained support for them, we now pass dma_sttrs->flags which is the expected unsigned long bit field. If anyone has serious interest in updating our ofed implementation they could look into this some more and remove the usage of struct dma_attrs entirely.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overview: This is the first stage of a RDMA stack upgrade introducing kernel changes only based on Linux 5.7-rc1. This patch is based on about four main areas of work: - Update of the IB uobjects system: - The memory holding so-called AH, CQ, PD, SRQ and UCONTEXT objects is now managed by ibcore. This also require some changes in the kernel verbs API. The updated verbs changes are typically about initialize and deinitialize objects, and remove allocation and free of memory. - Update of the uverbs IOCTL framework: - The parsing and handling of user-space commands has been completely refactored to integrate with the updated IB uobjects system. - Various changes and updates to the generic uverbs interfaces in device drivers including the new uAPI surface. - The mlx5_ib_devx.c in mlx5ib and related mlx5 core changes. Dependencies: - The mlx4ib driver code has been updated with the minimum changes needed. - The mlx5ib driver code has been updated with the minimum changes needed including DV support. Compatibility: - All user-space facing APIs are backwards compatible after this change. - All kernel-space facing RDMA APIs are backwards compatible after this change, with exception of ib_create_ah() and ib_destroy_ah() which takes a new flag. - The "ib_device_ops" structure exist, but only contains the driver ID and some structure sizes. Differences from Linux: - Infiniband drivers must use the INIT_IB_DEVICE_OPS() macro to set the sizes needed for allocating various IB objects, when adding IB device instances. Security: - PRIV_NET_RAW is needed to use raw ethernet transmit features. - PRIV_DRIVER is needed to use other privileged operations.

* mlx4/OFED: replace the struct net_device with struct ifnetBjoern A. Zeeb2021-06-184-15/+15
| | | | | | | | | | | | | | | | | Given all the code does operate on struct ifnet, the last step in this longer series of changes now is to rename struct net_device to struct ifnet (that is what it was defined to in the LinuxKPi code). While mlx4 and OFED are "shared" code the decision was made years ago to not write it based on the netdevice KPI but the native ifnet KPI for most of it. This commit simply spells this out and with that frees "struct netdevice" to be re-done on LinuxKPI to become a more native/mixed implementation over time as needed by, e.g., wireless drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The two functions in linux/inetdevice.h are highly FreeBSD/ifnet specific. This is a result of struct net_device being mapped to struct ifnet. The only known consumer of these functions are two files in the ofed/infiniband code. As a first step of cleaning up copy linux/inetdevice.h to rdma/ib_addr_freebsd.h. (It stayed a separate file to preserve copyright and license of the original file; otherwise it could be merged into ib_addr.h where more EPOCH/vnet/.. are already used). Slightly rename the function to not conflict with LinuxKPI in the future. Remove the three last, now unneeded includes of inetdevice.h and zap linux/inetdevice.h to an empty header file with only the forward include to netdevice.h remaining.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change include several changes as listed below all related to UAR. UAR is a special PCI memory area where the so-called doorbell register and blue flame register live. Blue flame is a feature for sending small packets more efficiently via a PCI memory page, instead of using PCI DMA. - All structures and functions named xxx_uuars were renamed into xxx_bfreg. - Remove partially implemented Blueflame support from mlx5en(4) and mlx5ib. - Implement blue flame register allocator. - Use blue flame register allocator in mlx5ib. - A common UAR page is now allocated by the core to support doorbell register writes for all of mlx5en and mlx5ib, instead of allocating one UAR per sendqueue. - Add support for DEVX query UAR. - Add support for 4K UAR for libmlx5.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variants in ibcore. Garbage supplied by user will cause to UCMA module provide zero memory size for memcpy(), because it wasn't checked, it will produce unpredictable results in rdma_resolve_addr(). There are several places in the ucma ABI where userspace can pass in a sockaddr but set the address family to AF_IB. When that happens, rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6, and the ucma kernel code might end up copying past the end of a buffer not sized for a struct sockaddr_ib. Fix this by introducing new variants int rdma_addr_size_in6(struct sockaddr_in6 *addr); int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr); that are type-safe for the types used in the ucma ABI and return 0 if the size computed is bigger than the size of the type passed in. We can use these new variants to check what size userspace has passed in before copying any addresses.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Optimize ibcore RoCE address handle creation from user-space.Hans Petter Selasky2018-03-052-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Get correct network device when accepting incoming RDMA connections in ibcore.Hans Petter Selasky2018-03-051-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch ensures the GID index is always used as a basis of resolving incoming RDMA connections, as compared to the GID value itself. Background: On a per infiniband port basis, the GID identifier is not a unique identifier! This assumption falls apart when VLAN ID, IPv6 scope ID and RoCE type, as supported by RoCE v2, is taken into account. This additional information is stored in the so-called GID attributes and is needed to correctly identify the destination network interface for an incoming connection. Different VLANs are allowed to define the same IPv4 addresses and especially for the default IPv6 link-local addresses or when using so-called containers or jails, this is true. The VNET information for the destination network interface is needed in order to perform the L2 address lookup in the right Virtual Network Stack context. Consequently old functions previously used by RoCE v1, like rdma_addr_find_smac_by_sgid() are impossible to support, because there can be multiple identical GIDs associated with the same infiniband port, and the answer to such a request becomes undefined. This function has been removed. MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=330507

* sys: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2715-15/+45
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.
