[PATCH v3] IB/sa: Resolving use-after-free in ib_nl_send_msg Hi, Please review the patch that follows. v3 addresses the previously raised concerns. Changes include - 1. To resolve the race where the timer can kick in before request has been sent out, we now add the request to the list after sending out the request. 2. To handle the race where the response can come in before we got a chance to add the req to the list, sending and adding the request to request list is done under spinlock - request_lock. 3. To make sure there is no blocking op/delay while holding the spinlock, using GFP_NOWAIT for memory allocation. Thanks Jason for providing your valuable feedback. Let me know if you have any suggestions or concerns. Thanks, Divya
