Vulnerability Title
RDMA/irdma: Fix sleep from invalid context BUG
Source: NVD (National Vulnerability Database)
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix sleep from invalid context BUG Taking the qos_mutex to process RoCEv2 QP's on netdev events causes a kernel splat. Fix this by removing the handling for RoCEv2 in irdma_cm_teardown_connections that uses the mutex. This handling is only needed for iWARP to avoid having connections established while the link is down or having connections remain functional after the IP address is removed. BUG: sleeping function called from invalid context at kernel/locking/mutex. Call Trace: kernel: dump_stack+0x66/0x90 kernel: ___might_sleep.cold.92+0x8d/0x9a kernel: mutex_lock+0x1c/0x40 kernel: irdma_cm_teardown_connections+0x28e/0x4d0 [irdma] kernel: ? check_preempt_curr+0x7a/0x90 kernel: ? select_idle_sibling+0x22/0x3c0 kernel: ? select_task_rq_fair+0x94c/0xc90 kernel: ? irdma_exec_cqp_cmd+0xc27/0x17c0 [irdma] kernel: ? __wake_up_common+0x7a/0x190 kernel: irdma_if_notify+0x3cc/0x450 [irdma] kernel: ? sched_clock_cpu+0xc/0xb0 kernel: irdma_inet6addr_event+0xc6/0x150 [irdma]
