2020-11-12RDMA/core: Postpone uobject cleanup on failure till FD closeLeon Romanovsky
Remove the ib_is_destroyable_retryable() concept. The idea here was to allow the drivers to forcibly clean the HW object even if they otherwise didn't want to (eg because of usecnt). This was an attempt to clean up in a world where drivers were not allowed to fail HW object destruction. Now that we are going back to allowing HW objects to fail destroy this doesn't make sense. Instead if a uobject's HW object can't be destroyed it is left on the uobject list and it is up to uverbs_destroy_ufile_hw() to clean it. Multiple passes over the uobject list allow hidden dependencies to be resolved. If that fails the HW driver is broken, throw a WARN_ON and leak the HW object memory. All the other tricky failure paths (eg on creation error unwind) have already been updated to this new model.

2020-08-18RDMA/mlx5: Enable sniffer when device is in switchdev modeMaor Gottlieb
In order to allow sniffer when the RDMA device is in switchdev mode, we don't need to set the source port when creating the sniffer rule.

2020-08-18RDMA: Remove constant domain argument from flow creation callLeon Romanovsky
The "domain" argument is constant and modern device (mlx5) doesn't support anything except IB_FLOW_DOMAIN_USER, so delete this extra parameter and simplify code.

2020-08-05RDMA/mlx5: Fix flow destination setting for RDMA TX flow tableMichael Guralnik
For RDMA TX flow table, set destination type to be 'port' and prevent creation of flows with TIR destination. As RDMA TX is an egress flow table the rules on this flow table should not forward traffic back to the NIC and should set the destination to be the port. Without the setting of this destination type flow rules on the RDMA TX flow tables are not created as FW invokes a syndrome for undefined destination for the rule.
