Title
RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08 Currently rsv_qp is freed before ib_unregister_device() is called on HIP08. During the time interval, users can still dereg MR and rsv_qp will be used in this process, leading to a UAF. Move the release of rsv_qp after calling ib_unregister_device() to fix it.

No remote packet processing reaches `free_mr_send_cmd_to_hw()`.\nAC:L - The attacker owns the consuming side of the race and can keep many threads permanently spinning in `ib_dereg_mr()`, so threads are continuously resident in the completely unsynchronized window between the `hr_dev-\u003estate` TOCTOU check and the dereference of `free_mr-\u003ersv_qp[]`/`rsv_cq`; whenever the routine teardown or hardware reset path runs `free_mr_exit()`, the race is won reliably, and the freed `struct hns_roce_qp` is a plain kmalloc object the attacker can spray.\nPR:L - Only an ordinary unprivileged local account is needed \u2014 opening the uverbs device, allocating a PD and registering a small MR (within the default RLIMIT_MEMLOCK, so no CAP_IPC_LOCK), then deregistering it, is enough to enter `hns_roce_v2_dereg_mr()`. No root, CAP_NET_ADMIN, or capability in any namespace is required.\nUI:N - The attacker\u0027s own dereg-MR loop drives the vulnerable path entirely on its own; no victim action, file open, or mount is needed, and the teardown side is a routine system event rather than a user-performed step.\nS:U - The use-after-free corrupts kernel heap state within the same kernel security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is a use-after-free on a heap-allocated `struct hns_roce_qp` and `struct hns_roce_cq`; after slab reallocation, `hns_roce_v2_post_send()` and `hns_roce_v2_poll_cq()` read pointers, MTR translation state, and CQE contents out of attacker-groomed memory, yielding an arbitrary kernel-memory read primitive.\nI:H - `hns_roce_v2_post_send()` writes a WQE and `qp-\u003esq.wrid[wqe_idx]` through addresses computed from the freed object\u0027s fields and takes a spinlock on freed memory, so reclaiming the slab gives a controlled kernel write usable for control-flow hijack and privilege escalation; `mutex_lock()` on a `mutex_destroy()`ed lock compounds the corruption.\nA:H - Even without successful heap grooming, dereferencing the freed reserved QP/CQ and locking a destroyed mutex reliably produces a KASAN splat, list corruption, or kernel oops/panic, taking the RDMA-serving host down."
