About this tag
The hns rdma tag on WindowsForum.com covers discussions about the Linux kernel's RDMA HNS (Hisilicon) driver, particularly a vulnerability (CVE-2024-43872) that causes soft lockups under heavy Completion Event Queue Entry (CEQE) load. The fix moves CEQE processing from hard IRQ to a bottom-half workqueue and limits the number of CEQEs processed per call, preventing CPU freezes. This tag is relevant for Linux system administrators and developers working with RDMA on Hisilicon hardware, focusing on kernel stability and interrupt handling.
