RDMA: Check flags during create_cq
Each driver should check that the CQ attrs is supported. Unfortuantely when flags was added to the CQ attrs the drivers were not updated, uverbs_ex_cmd_mask was used to block it. This was missed when create CQ was converted to ioctl, so non-zero flags could have been passed into drivers. Check that flags is zero in all drivers that don't use it, remove IB_USER_VERBS_EX_CMD_CREATE_CQ from uverbs_ex_cmd_mask. Fixes: 41b2a71fc848 ("IB/uverbs: Move ioctl path of create_cq and destroy_cq to a new file") Link: https://lore.kernel.org/r/7-v1-caa70ba3d1ab+1436e-ucmd_mask_jgg@nvidia.com Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
