IB/core: Make ib_alloc_device init the kobject

2015-08-30T22:08:50+00:00

This gets rid of the weird in-between state where struct ib_device was allocated but the kobject didn't work. Consequently ib_device_release is now guaranteed to be called in all situations and we needn't duplicate its kfrees on error paths. Signed-off-by: Jason Gunthorpe Signed-off-by: Doug Ledford

IB: Add rdma_cap_ib_switch helper and use where appropriate

2015-07-14T17:20:08+00:00

Persuant to Liran's comments on node_type on linux-rdma mailing list: In an effort to reform the RDMA core and ULPs to minimize use of node_type in struct ib_device, an additional bit is added to struct ib_device for is_switch (IB switch). This is needed to be initialized by any IB switch device driver. This is a NEW requirement on such device drivers which are all "out of tree". In addition, an ib_switch helper was added to ib_verbs.h based on the is_switch device bit rather than node_type (although those should be consistent). The RDMA core (MAD, SMI, agent, sa_query, multicast, sysfs) as well as (IPoIB and SRP) ULPs are updated where appropriate to use this new helper. In some cases, the helper is now used under the covers of using rdma_[start end]_port rather than the open coding previously used.

IB/mad: Add support for additional MAD info to/from drivers

2015-06-12T18:49:17+00:00

In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect. Signed-off-by: Ira Weiny Signed-off-by: Doug Ledford

IB/core: Add per port immutable struct to ib_device

2015-05-20T16:38:13+00:00

As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data. Signed-off-by: Ira Weiny Signed-off-by: Doug Ledford

IB/core: Fix kobject leak on device register error flow

2014-06-05T16:37:10+00:00

The ports kobject isn't being released during error flow in device registration. This patch refactors the ports kobject cleanup into a single function called from both the error flow in device registration and from the unregistration function. A couple of attributes aren't being deleted (iw_stats_group, and ib_class_attributes). While this may be handled implicitly by the destruction of their kobjects, it seems better to handle all the attributes the same way.

IB/core: Fix port kobject deletion during error flow

2014-06-04T17:03:49+00:00

When encountering an error during the add_port function, adding a port to sysfs, the port kobject is freed without being deleted from sysfs. Instead of freeing it directly, the patch uses kobject_put to release the kobject and delete it. Signed-off-by: Haggai Eran Signed-off-by: Roland Dreier

IB/core: Remove unneeded kobject_get/put calls

2014-06-04T17:03:49+00:00

The ib_core module will call kobject_get on the parent object of each kobject it creates. This is redundant since kobject_add does that anyway. As a side effect, this patch should fix leaking the ports kobject and the device kobject during unregister flow, since the previous code didn't seem to take into account the kobject_get calls on behalf of the child kobjects.
