RDMA/cma: Use rdma_read_gid_attr_ndev_rcu to access netdev

2019-05-03T14:10:03Z

To access the netdevice of the GID attribute, use an existing API rdma_read_gid_attr_ndev_rcu(). This further reduces dependency on open access to netdevice of GID attribute. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

RDMA: Introduce and use GID attr helper to read RoCE L2 fields

2019-05-03T14:10:02Z

Instead of RoCE drivers figuring out vlan, smac fields while working on QP/AH, provide a helper routine to read the L2 fields such as vlan_id and source mac address. This moves logic from mlx5 driver to core for wider usage for RoCE ports. This is a preparation patch to allow detaching netdev in subsequent patch.

RDMA/smc: Replace ib_query_gid with rdma_get_gid_attr

2018-08-17T22:45:51Z

All RDMA ULPs should be using rdma_get_gid_attr instead of ib_query_gid. Convert SMC to use the new API. In the process correct some confusion with gid_type - if attr->ndev is !NULL then gid_type can never be IB_GID_TYPE_IB by definition. IB_GID_TYPE_ROCE shares the same enum value and is probably what was intended here. Reviewed-by: Parav Pandit Signed-off-by: Jason Gunthorpe

Revert "net/smc: Replace ib_query_gid with rdma_get_gid_attr"

2018-08-16T20:03:34Z

This reverts commit ddb457c6993babbcdd41fca638b870d2a2fc3941. The include rdma/ib_cache.h is kept, and we have to add a memset to the compat wrapper to avoid compiler warnings in gcc-7 This revert is done to avoid extensive merge conflicts with SMC changes in netdev during the 4.19 merge window.

IB/cache: Restore compatibility for ib_query_gid

2018-07-27T16:08:34Z

Code changes in smc have become so complicated this cycle that the RDMA patches to remove ib_query_gid in smc create too complex merge conflicts. Allow those conflicts to be resolved by using the net/smc hunks by providing a compatibility wrapper. During the second phase of the merge window this wrapper will be deleted and smc updated to use the new API. Reported-by: Stephen Rothwell Reviewed-by: Parav Pandit Signed-off-by: Jason Gunthorpe

RDMA/core: Remove unused ib cache functions

2018-06-25T20:19:57Z

Now that all users have been converted to use the version of these APIs that returns a gid_attr pointer we can delete the old entry points. Signed-off-by: Parav Pandit Signed-off-by: Jason Gunthorpe Signed-off-by: Leon Romanovsky

IB/core: Provide rdma_ versions of the gid cache API

2018-06-18T17:09:05Z

These versions are functionally similar but all return gid_attrs and related information via reference instead of via copy. The old API is preserved, implemented as wrappers around the new, until all callers can be converted. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

IB/core: Introduce GID attribute get, put and hold APIs

2018-06-18T17:09:05Z

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.

IB/core: Reduce the places that use zgid

2018-05-24T15:39:25Z

Instead of open coding memcmp() to check whether a given GID is zero or not, use a helper function to do so, and replace instances of memcpy(z,&zgid) with memset. Signed-off-by: Parav Pandit Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

IB/core: Fix comments of GID query functions

2018-03-15T20:40:36Z

Exported symbol's comments should be with function definition and not in the header file. Therefore comments of ib_find_cached_gid() and ib_find_cached_gid_by_port() functions are moved closer to their definitions. The function name in then comment is different than the actual function name, fix it to be same as ib_cache_gid_find_by_filter(). Also current comment section of ib_find_cached_gid_by_port() contains the desciption of ib_find_cached_gid(), fix that as well.
