The sgid_attr will ultimately replace the sgid_index in the ah_attr. This will allow for all layers to have a consistent view of what gid table entry was selected as processing runs through all stages of the stack. This commit introduces the pointer and ensures it is set before calling any driver callback that includes a struct ah_attr callback, allowing future patches to adjust both the drivers and the callers to use sgid_attr instead of sgid_index.

Document this (it's implicitly true due to sleeping operations already in use in both registration and deregistration). Use this fact to use spin_lock_irq instead of spin_lock_irqsave. This improves performance slightly. Signed-off-by:

struct rxe_global_route and struct ib_global_route are not the same thing and should not be memcpy'd over each other, do a member by member copy instead. This allows the layout of the in-kernel struct ib_global_route to be changed without breaking rxe. Reviewed-by:

Commit f43c00c0 ("i40iw: Extend port reuse support for listeners") introduces a sparse warning: include/linux/spinlock.h:365:9: sparse: context imbalance in 'i40iw_manage_apbvt' - unexpected unlock Fix this by reorganizing the acquire/release of locks in i40iw_manage_apbvt and add a new function i40iw_cqp_manage_abvpt_cmd to perform the CQP command. Also, use __clear_bit and __test_and_set_bit as we do not need atomic versions. Fixes: f43c00c0 ("i40iw: Extend port reuse support for listeners") Suggested-by:

rxe_netdev_from_av can now be done by the core code directly from the gid_attrs, no need for a helper in the driver. ib_find_cached_gid_by_port can be switched to use the rdma version here as well. Signed-off-by:

If the gid_attr argument is NULL then the functions behave identically to rdma_query_gid. ib_query_gid just calls ib_get_cached_gid, so everything can be consolidated to one function. Now that all callers either use rdma_query_gid() or ib_get_cached_gid(), ib_query_gid() API is removed. Signed-off-by:

Push the copy of the gid_attr into the SMC code. This probably doesn't push it far enough, as it looks like the conn->lgr should potentially hold the reference for its lifetime. Signed-off-by:

This patch introduces three APIs, rdma_get_gid_attr(), rdma_put_gid_attr(), and rdma_hold_gid_attr() which expose the reference counting for GID table entries to the entire stack. The kref counting is based on the struct ib_gid_attr pointer Later patches will convert more cache query function to return struct ib_gid_attrs. Signed-off-by:

Now that ib_gid_attr contains the GID, make use of that in the add_gid() callback functions for the provider drivers to simplify the add_gid() implementations. Signed-off-by:
-
Parav Pandit authored
In order to be able to expose pointers to the ib_gid_attrs in the GID table we need to make it so the value of the pointer cannot be changed. Thus each GID table entry gets a unique piece of kref'd memory that is written only during initialization and remains constant for its lifetime. This eventually will allow the struct ib_gid_attrs to be returned without copy from many of query the APIs, but it also provides a way to track when all users of a HW table index go away. For roce we no longer allow an in-use HW table index to be re-used for a new an different entry. When a GID table entry needs to be removed it is hidden from the find API, but remains as a valid HW index and all ib_gid_attr points remain valid. The HW index is not relased until all users put the kref. Later patches will broadly replace the use of the sgid_index integer with the kref'd structure. Ultimately this will prevent security problems where the OS changes the properties of a HW GID table entry while an active user object is still using the entry. Signed-off-by:

There are at max one or two default GIDs for RoCE. Instead of storing a default GID property for all the GIDs, store default GID indices as individual bit per table. This allows a future simplification to get rid of the GID property field. Signed-off-by:
-
Parav Pandit authored
When default GIDs are added, their gid type is set by ib_cache_gid_set_default_gid(). There is no need to set the gid type of a free GID entry during GID table initialization. Signed-off-by:
