Update the struct ib_client for all modules exporting cdevs related to the ibdevice to also implement RDMA_NLDEV_CMD_GET_CHARDEV. All cdevs are now autoloadable and discoverable by userspace over netlink instead of relying on sysfs. uverbs also exposes the DRIVER_ID for drivers that are able to support driver id binding in rdma-core.

Allow userspace to issue a netlink query against the ib_device for something like "uverbs" and get back the char dev name, inode major/minor, and interface ABI information for "uverbs0". Since we are now in netlink this can also trigger a module autoload to make the uverbs device come into existence. Largely this will let us replace searching and reading inside sysfs to setup devices, and provides an alternative (using driver_id) to device name based provider binding for things like rxe.

This driver was first merged over 10 years ago and has not seen major activity by the authors in the last 7 years. However, in that time it has been patched 150 times to adapt it to changing kernel APIs. Further, the hardware has several issues, like not supporting 64 bit DMA, that make it rather uninteresting for use with modern systems and RDMA. Signed-off-by:

The default action for unlisted tests is "not-supported", so given that ipoib doesn't support ETH_SS_TEST, there is no need to check for it in the case statements, just let it get caught by the default: case. Fixes: e3614bc9 ("IB/ipoib: Add readout of statistics using ethtool") Signed-off-by:

When user post recv a srq with multiple sges, the hardware will get the last correct sge and count the sge numbers according to the specific identifier with lkey. For example, when the driver fills the sges with every wr less than the max sge that the user configured when creating srq, the hardware will stop getting the sge according to the specific lkey in the sge. However, it will always end with the first sge in the current post srq recv interface implementation. Fixes: c7bcb134 ("RDMA/hns: Add SRQ support for hip08 kernel mode") Signed-off-by:

The function srp_parse_in() is used both for parsing source address specifications and for target address specifications. Target addresses must have a port number.

When the user submits more than 32 work request to a srq queue at a time, it needs to find the corresponding number of entries in the bitmap in the idx queue. However, the original lookup function named ffs only processes 32 bits of the array element, When the number of srq wqe issued exceeds 32, the ffs will only process the lower 32 bits of the elements, it will not be able to get the correct wqe index for srq wqe.

If the kzalloc() fails then we should return ERR_PTR(-ENOMEM). In the current code it's possible that the kzalloc() fails and the radix_tree_insert() inserts the NULL pointer successfully and we return the NULL "elm" pointer to the caller. That results in a NULL pointer dereference. Fixes: 9ed3e5f4 ("IB/uverbs: Build the specs into a radix tree at runtime") Signed-off-by:

For infiniband code that retains pages via get_user_pages*(), release those pages via the new put_user_page(), or put_user_pages*(), instead of put_page() This is a tiny part of the second step of fixing the problem described in [1]. The steps are: 1) Provide put_user_page*() routines, intended to be used for releasing pages that were pinned via get_user_pages*(). 2) Convert all of the call sites for get_user_pages*(), to invoke put_user_page*(), instead of put_page(). This involves dozens of call sites, and will take some time. 3) After (2) is complete, use get_user_pages*() and put_user_page*() to implement tracking of these pages. This tracking will be separate from the existing struct page refcounting. 4) Use the tracking and identification of these pages, to implement special handling (especially in writeback paths) when the pages are backed by a filesystem. Again, [1] provides details as to why that is desirable. [1] https://lwn.net/Articles/753027/ : "The Trouble with get_user_pages()" Reviewed-by:

When hip08 set gid, it will call spin_unlock_bh when send cmq. if main.ko call spin_lock_irqsave firstly, and the kernel is before commit f71b74bc ("irq/softirqs: Use lockdep to assert IRQs are disabled/enabled"), it will cause WARN_ON_ONCE because of calling spin_unlock_bh in disable context. In fact, the spin_lock_irqsave in main.ko is only used for hip06, and should be placed in hns_roce_hw_v1.c. hns_roce_hw_v2.c uses its own spin_unlock_bh and does not need main.ko manage spin_lock.
