In the Linux kernel, the following vulnerability has been resolved:

RDMA/iwcm: Fix workqueue list corruption by removing work_list

The commit e1168f0 ("RDMA/iwcm: Simplify cm_event_handler()") changed the work submission logic to unconditionally call queue_work() with the expectation that queue_work() would have no effect if work was already pending. The problem is that a free list of struct iwcm_work is used (for which struct work_struct is embedded), so each call to queue_work() is basically unique and therefore does indeed queue the work.

This causes a problem in the work handler which walks the work_list until it's empty to process entries. This means that a single run of the work handler could process item N+1 and release it back to the free list while the actual workqueue entry is still queued. It could then get reused (INIT_WORK...) and lead to list corruption in the workqueue logic.

Fix this by just removing the work_list. The workqueue already does this for us.

This fixes the following error that was observed when stress testing with ucmatose on an Intel E830 in iWARP mode:

[ 151.465780] list_del corruption. next->prev should be ffff9f0915c69c08, but was ffff9f0a1116be08.
