From: Leon Romanovsky <leonro@xxxxxxxxxxxx> >From Parav: Now that all the drivers are using the sgid_attr, make it persist throughout the CM code as well instead of storing loose ifindex or sgid_index values. This series is a prerequisite for enabling namespaces for RoCE. It ensures that while GID entry being used, it cannot get deleted. When the last user of the GID entry releases the reference, the GID entry is released in the software cache and in the HCA. Series also removes dependency of net+ifindex in the path record entry for RoCE. Both of those fields of the netdev can change and storing net namespace without holding reference will lead to use-after-free crash. Therefore it is removed. Netdevice information for RoCE will be provided via referenced gid attribute in ib_cm_req entry in future.
