Revision 810dbc69087b08fd53e1cdd6c709f385bc2921ad authored by Bernard Metzler on 02 March 2020, 18:16:14 UTC, committed by Jason Gunthorpe on 04 March 2020, 18:28:25 UTC
The dealloc_work_entries() function must update the work_free_list pointer
while freeing its entries, since potentially called again on same list. A
second iteration of the work list caused system crash. This happens, if
work allocation fails during cma_iw_listen() and free_cm_id() tries to
free the list again during cleanup.
Fixes: 922a8e9fb2e0 ("RDMA: iWARP Connection Manager.")
