In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix log flood after cmd_mbox failure
hns_roce_cmd_mbox() is the command interface between driver and
hardware. When hardware is abnormal, the unlimited error printings
after hns_roce_cmd_mbox() failure will cause log flood and even
system crash.
Replace ibdev_err() and ibdev_warn() with their ratelimited versions
in the error handling path after hns_roce_cmd_mbox() (and its wrappers
hns_roce_create_hw_ctx/hns_roce_destroy_hw_ctx) fails.
