RDMA/core: create struct ib_port_cache

2017-01-24T21:20:37+00:00

As Jason suggested, we have 4 elements for per port arrays, it's better to have a separate structure to represent them. It simplifies code a bit, ~ 30 lines of code less :) Signed-off-by: Jack Wang Reviewed-by: Michael Wang Signed-off-by: Doug Ledford

IB/core: Release allocated memory in cache setup failure

2016-12-03T18:12:52+00:00

The failure in ib_cache_setup_one function during ib_register_device will leave leaked allocated memory. Fixes: 03db3a2d81e6 ("IB/core: Add RoCE GID table management") Signed-off-by: Leon Romanovsky Signed-off-by: Doug Ledford

IB/core: Fix no default GIDs when netdevice reregisters

2016-06-23T14:03:57+00:00

Currently, when the netdevice returned by get_netdev is unregistered, we delete all GIDs (including the default GIDs) and reset their attributes. Therefore, when we re-register it, no default GIDs will be assigned (as their "default GID") attribute will be reset. Fixing this by keeping "default GID" attribute.

IB/core: Fix removal of default GID cache entry

2016-06-07T13:50:53+00:00

When deleting a default GID from the cache, its gid_type field is set to 0. This could set the gid_type to RoCE v1 for a RoCE v2 default GID, essentially making it inaccessible to future modifications, since it is no longer found by find_gid(). This fix preserves the gid_type value for default gids during cache operations.

IB/core: Fix oops in ib_cache_gid_set_default_gid

2016-04-23T00:26:44+00:00

When we fail to find the default gid index, we can't continue processing in this routine or else we will pass a negative index to later routines resulting in invalid memory access attempts and a kernel oops. Fixes: 03db3a2d81e6 (IB/core: Add RoCE GID table management) Signed-off-by: Doug Ledford

IB/core: Eliminate sparse false context imbalance warning

2016-01-19T20:26:21+00:00

When write_gid function needs to do a sleep-able operation, it unlocks table->rwlock and then relocks it. Sparse complains about context imbalance. This is safe as write_gid is always called with table->rwlock. write_gid protects from simultaneous writes to this GID entry by setting the GID_TABLE_ENTRY_INVALID flag.
