nvmet-rdma: fix double free of rdma queue

2020-04-07T16:33:45Z

In case rdma accept fails at nvmet_rdma_queue_connect(), release work is scheduled. Later on, a new RDMA CM event may arrive since we didn't destroy the cm-id and call nvmet_rdma_queue_connect_fail(), which schedule another release work. This will cause calling nvmet_rdma_free_queue twice. To fix this we implicitly destroy the cm_id with non-zero ret code, which guarantees that new rdma_cm events will not arrive afterwards. Also add a qp pointer to nvmet_rdma_queue structure, so we can use it when the cm_id pointer is NULL or was destroyed.

nvme-fc: Revert "add module to ops template to allow module references"

2020-04-04T07:09:39Z

The original patch was to resolve the lldd being able to be unloaded while being used to talk to the boot device of the system. However, the end result of the original patch is that any driver unload while a nvme controller is live via the lldd is now being prohibited. Given the module reference, the module teardown routine can't be called, thus there's no way, other than manual actions to terminate the controllers.

nvmet-rdma: fix bonding failover possible NULL deref

2020-04-04T07:06:55Z

RDMA_CM_EVENT_ADDR_CHANGE event occur in the case of bonding failover on normal as well as on listening cm_ids. Hence this event will immediately trigger a NULL dereference trying to disconnect a queue for a cm_id that actually belongs to the port. To fix this we provide a different handler for the listener cm_ids that will defer a work to disable+(re)enable the port which essentially destroys and setups another listener cm_id Reported-by: Alex Lyakas Signed-off-by: Sagi Grimberg Reviewed-by: Max Gurtovoy Tested-by: Alex Lyakas Signed-off-by: Christoph Hellwig

nvme-fcloop: fix deallocation of working context

2020-03-31T14:19:48Z

There's been a longstanding bug of LS completions which freed ls ops, particularly the disconnect LS, while executing on a work context that is in the memory being free. Not a good thing to do. Rework LS handling to make callbacks in the rport context rather than the ls_request context.
