2018-12-18RDMA: Cleanup undesired pd->uobject usageShamir Rabinovitch
Drivers should be using udata to determine if a method is invoked from user space or kernel space. A pd does not necessarily say a different objects is kernel or user. Transforming the tests to use udata eliminates a large number of uobject references from the drivers.

2018-12-18RDMA/restrack: Resource-tracker should not use uobject pointersShamir Rabinovitch
Having uobject pointer embedded in ib core objects is not aligned with a future shared ib_x model. The resource tracker only does this to keep track of user/kernel objects - track this directly instead.

2018-12-18IB/uverbs: Add support to advise_mrMoni Shoua
Add new ioctl method for the MR object - ADVISE_MR. This command can be used by users to give an advice or directions to the kernel about an address range that belongs to memory regions. A new ib_device callback, advise_mr(), is introduced here to suupport the new command. This command takes the following arguments: - pd: The protection domain to which all memory regions belong - advice: The type of the advice * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH - Pre-fetch a range of an on-demand paging MR * IB_UVERBS_ADVISE_MR_ADVICE_PREFETCH_WRITE - Pre-fetch a range of an on-demand paging MR with write intention - flags: The properties of the advice * IB_UVERBS_ADVISE_MR_FLAG_FLUSH - Operation must end before return to the caller - sg_list: The list of memory ranges - num_sge: The number of memory ranges in the list - attrs: More attributes to be parsed by the provider Signed-off-by: Moni Shoua <monis@mellanox.com> Reviewed-by: Guy Levi <guyle@mellanox.com> Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2018-12-18IB/uverbs: Add helper to get array size from ptr attributeMoni Shoua
When the parser of an ioctl command has the knowledge that a ptr attribute in a bundle represents an array of structures, it is useful for it to know the number of elements in the array. This is done by dividing the attribute length with the element size.

2018-12-18RDMA/core: Delete RoCE GID in hw when corresponding IP is deletedParav Pandit
Currently a RoCE GID entry is removed from the hardware when all references to the GID entry drop to zero. This is a change in behavior from before the fixed patch. The GID entry should be removed from the hardware when GID entry deletion is requested. This allows the driver terminate ongoing traffic through the RoCE GID. While a GID is deleted from the hardware, GID slot in the software GID cache is not freed. GID slot is freed once all references of such GID are dropped. This continue to ensure that such GID slot of hardware is not allocated to new GID entry allocation request. It is allocated once all references to GID entry drop. This approach allows drivers to put a tombestone of some kind on the HW GID index to block the traffic.

Now that the handlers do not process their own udata we can make a sensible ioctl that wrappers them.
