61e51682 - RDMA/uverbs: Introduce UCAP (User CAPabilities) API

Thu, 06 Mar 2025 11:51:26 +0000

RDMA/uverbs: Introduce UCAP (User CAPabilities) APIImplement a new User CAPabilities (UCAP) API to provide fine-grainedcontrol over specific firmware features.This approach offers more granular capabilities than the existing Linuxcapabilities, which may be too generic for certain FW features.This mechanism represents each capability as a character device withroot read-write access. Root processes can grant users specialprivileges by allowing access to these character devices (e.g., usingchown).UCAP character devices are located in /dev/infiniband and the class pathis /sys/class/infiniband_ucaps.Signed-off-by: Chiara Meiohas Link: https://patch.msgid.link/5a1379187cd21178e8554afc81a3c941f21af22f.1741261611.git.leon@kernel.orgReviewed-by: Yishai Hadas Reviewed-by: Zhu Yanjun Signed-off-by: Leon Romanovsky List of files: /linux-6.15/drivers/infiniband/core/Makefile

368c0159 - RDMA/umem: Support importing dma-buf as user memory region

Tue, 15 Dec 2020 21:27:13 +0000

RDMA/umem: Support importing dma-buf as user memory regionDma-buf is a standard cross-driver buffer sharing mechanism that can beused to support peer-to-peer access from RDMA devices.Device memory exported via dma-buf is associated with a file descriptor.This is passed to the user space as a property associated with the bufferallocation. When the buffer is registered as a memory region, the filedescriptor is passed to the RDMA driver along with other parameters.Implement the common code for importing dma-buf object and mapping dma-bufpages.Link: https://lore.kernel.org/r/1608067636-98073-2-git-send-email-jianxin.xiong@intel.comSigned-off-by: Jianxin Xiong Reviewed-by: Sean Hefty Acked-by: Michael J.

75874b3d - RDMA/cm: Replace pr_debug() call sites with tracepoints

Mon, 17 Aug 2020 13:53:16 +0000

RDMA/cm: Replace pr_debug() call sites with tracepointsIn the interest of converging on a common instrumentation infrastructure,modernize the pr_debug() call sites added by commit 119bf81793ea ("IB/cm:Add debug prints to ib_cm"). The new tracepoints appear in a new "ib_cma"subsystem.The conversion is somewhat mechanical. Someone more familiar with thesemantics of the recorded information might suggest additional datacapture.Some benefits include:- Tracepoints enable "always on" reporting of these errors- The error records are structured and compact- Tracepoints provide hooks for eBPF scriptsSample output: nfsd-1954 [003] 62.017901: icm_dreq_skipped: local_id=1998890974 remote_id=1129750393 state=DREQ_RCVD lap_state=LAP_UNINITLink: https://lore.kernel.org/r/159767239665.2968.10613294222688696646.stgit@klimt.1015granger.netSigned-off-by: Chuck Lever Signed-off-by: Jason Gunthorpe List of files: /linux-6.15/drivers/infiniband/core/Makefile

Fri, 10 Aug 2018 02:14:36 +0000

IB/uverbs: Build the specs into a radix tree at runtimeThis radix tree datastructure is intended to replace the 'hash' structureused today for parsing ioctl methods during system calls. This firstcommit introduces the structure and builds it from the existing .rodatadescriptions.The so-called hash arrangement is actually a 5 level open coded radix tree.This new version uses a 3 level radix tree built using the radix treelibrary.Overall this is much less code and much easier to build as the radix treeAPI allows for dynamic modification during the building. There is a smallmemory penalty to pay for this, but since the radix tree is allocated ona per device basis, a few kb of RAM seems immaterial considering thegained simplicity.The radix tree is similar to the existing tree, but also has a 'attr_bkey'concept, which is a small value'd index for each method attribute. This isused to simplify and improve performance of everything in the nextpatches.Signed-off-by: Jason Gunthorpe Reviewed-by: Leon Romanovsky Reviewed-by: Michael J.
