Pull drm updates from Dave Airlie: "The biggest highlight is that the accel subsystem framework is merged. Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs. I think all of those should have been acked/reviewed by relevant parties.

Pull nfsd updates from Chuck Lever: "This release introduces support for the CB_RECALL_ANY operation. NFSD can send this operation to request that clients return any delegations they choose. The server uses this operation to handle low memory scenarios or indicate to a client when that client has reached the maximum number of delegations the server supports. The NFSv4.2 READ_PLUS operation has been simplified temporarily whilst support for sparse files in local filesystems and the VFS is improved. Two major data structure fixes appear in this release: - The nfs4_file hash table is replaced with a resizable hash table to reduce the latency of NFSv4 OPEN operations. - Reference counting in the NFSD filecache has been hardened against races. In furtherance of removing support for NFSv2 in a subsequent kernel release, a new Kconfig option enables server-side support for NFSv2 to be left out of a kernel build.

2022-10-19RDMA/cma: Use output interface for net_dev checkHåkon Bugge1-1/+1
Commit 27cfde795a96 ("RDMA/cma: Fix arguments order in net device validation") swapped the src and dst addresses in the call to validate_net_dev(). As a consequence, the test in validate_ipv4_net_dev() to see if the net_dev is the right one, is incorrect for port 1 <-> 2 communication when the ports are on the same sub-net. This is fixed by denoting the flowi4_oif as the device instead of the incoming one. The bug has not been observed using IPv6 addresses.

2022-09-22RDMA/cma: Multiple path records support with netlink channelMark Zhang2-84/+221
Support receiving inbound and outbound IB path records (along with GMP PathRecord) from user-space service through the RDMA netlink channel. The LIDs in these 3 PRs can be used in this way: 1. GMP PR: used as the standard local/remote LIDs; 2. DLID of outbound PR: Used as the "dlid" field for outbound traffic; 3. DLID of inbound PR: Used as the "dlid" field for outbound traffic in responder side. This is aimed to support adaptive routing. With current IB routing solution when a packet goes out it's assigned with a fixed DLID per target, meaning a fixed router will be used. The LIDs in inbound/outbound path records can be used to identify group of routers that allow communication with another subnet's entity. With them packets from an inter-subnet connection may travel through any router in the set to reach the target. As confirmed with Jason, when sending a netlink request, kernel uses LS_RESOLVE_PATH_USE_ALL so that the service knows kernel supports multiple PRs.

2022-09-05IB/core: Fix a nested dead lock as part of ODP flowYishai Hadas1-1/+1
Fix a nested dead lock as part of ODP flow by using mmput_async(). From the below call trace [1] can see that calling mmput() once we have the umem_odp->umem_mutex locked as required by ib_umem_odp_map_dma_and_lock() might trigger in the same task the exit_mmap()->__mmu_notifier_release()->mlx5_ib_invalidate_range() which may dead lock when trying to lock the same mutex. Moving to use mmput_async() will solve the problem as the above exit_mmap() flow will be called in other task and will be executed once the lock will be available.

Fix the order of source and destination addresses when resolving the route between server and client to validate use of correct net device. The reverse order we had so far didn't actually validate the net device as the server would try to resolve the route to itself, thus always getting the server's net device. The issue was discovered when running cm applications on a single host between 2 interfaces with same subnet and source based routing rules. When resolving the reverse route the source based route rules were ignored.

2022-06-16RDMA/core: Add a netevent notifier to cmaPatrisious Haddad1-0/+81
Add a netevent callback for cma, mainly to catch NETEVENT_NEIGH_UPDATE. Previously, when a system with failover MAC mechanism change its MAC address during a CM connection attempt, the RDMA-CM would take a lot of time till it disconnects and timesout due to the incorrect MAC address. Now when we get a NETEVENT_NEIGH_UPDATE we check if it is due to a failover MAC change and if so, we instantly destroy the CM and notify the user in order to spare the unnecessary waiting for the timeout.

Add to the cma, a tree that keeps track of all rdma_id_private channels that were created while in RoCE mode. The IDs are sorted first according to their netdevice ifindex then their destination IP. And for IDs with matching IP they would be at the same node in the tree, since the tree data is a list of all ids with matching destination IP. The tree allows fast and efficient lookup of ids using an ifindex and IP address which is useful for identifying relevant net_events promptly.

2022-04-09RDMA/core: Delete IPsec flow action logic from the coreLeon Romanovsky2-384/+1
The removal of mlx5 flow steering logic, left the kernel without any RDMA drivers that implements flow action callbacks supplied by RDMA/core. Any user access to them caused to EOPNOTSUPP error, which can be achieved by simply removing ioctl implementation.

2022-04-08IB/SA: Replace usage of found with dedicated list iterator variableJakob Koschel1-8/+8
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-04-07dma-buf: add enum dma_resv_usage v4Christian König1-1/+2
This change adds the dma_resv_usage enum and allows us to specify why a dma_resv object is queried for its containing fences. Additional to that a dma_resv_usage_rw() helper function is added to aid retrieving the fences for a read or write userspace submission. This is then deployed to the different query functions of the dma_resv object and all of their users. When the write paratermer was previously true we now use DMA_RESV_USAGE_WRITE and DMA_RESV_USAGE_READ otherwise. v2: add KERNEL/OTHER in separate patch v3: some kerneldoc suggestions by Daniel v4: some more kerneldoc suggestions by Daniel, fix missing cases lost in the rebase pointed out by Bas.

2022-04-06RDMA: Split kernel-only global device caps from uverbs device capsJason Gunthorpe3-9/+7
Split out flags from ib_device::device_cap_flags that are only used internally to the kernel into kernel_cap_flags that is not part of the uapi. This limits the device_cap_flags to being the same bitmap that will be copied to userspace. This cleanly splits out the uverbs flags from the kernel flags to avoid confusion in the flags bitmap. Add some short comments describing which each of the kernel flags is connected to. Remove unused kernel flags.
