2017-08-24RDMA/mthca: Make explicit conversion to 64bit valueLeon Romanovsky
The "lg" variable is declared as int so in all places where this variable is used as a shift operand, the output will be int too. This produces the following smatch warning: drivers/infiniband/hw/mthca/mthca_cmd.c:701 mthca_map_cmd() warn: should '1 << lg' be a 64 bit type? Simple declaration of "1" to be "1ULL" will fix the issue.

2017-08-22IB/core: Fix input len in multiple user verbsAmrani, Ram
Most user verbs pass user data to the kernel with the inclusion of the ib_uverbs_cmd_hdr structure. This is problematic because the vendor has no ideas if the verb was called by a legacy verb or an extended verb. Also, the incosistency between the verbs is confusing.

2017-08-10RDMA: Simplify get firmware interfaceLeon Romanovsky
There is a need to forward FW version to user space application through RDMA netlink. In order to make it safe, there is need to declare nla_policy and limit the size of FW string. The new define IB_FW_VERSION_NAME_MAX will limit the size of FW version string. That define was chosen to be equal to ETHTOOL_FWVERS_LEN, because many drivers anyway are limited by that value indirectly. The introduction of this define allows us to remove the string size from get_fw_str function signature. Signed-off-by: Leon Romanovsky <leonro@mellanox.com>

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers.

Applications must not assume that max_sge and max_sge_rd are the same, Hence expose max_sge_rd correctly as well. Reported-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2015-07-14IB/mad: Remove improper use of BUG_ONIra Weiny
We recently added BUG_ON's which were inappropriate for a condition which should never happen. Change these to be WARN_ON_ONCE as a debugging aid.

2015-06-12IB/mad: Add support for additional MAD info to/from driversIra Weiny
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.

2015-06-12IB/core: Add ability for drivers to report an alternate MAD size.Ira Weiny
Add max MAD size to the device immutable data set and have all drivers that support MADs report the current IB MAD size (IB_MGMT_MAD_SIZE) to the core. Verify MAD size data in both the MAD core and when reading the immutable data. OPA drivers will report alternate MAD sizes in subsequent patches.

2015-06-12IB/mad: Support alternate Base Versions when creating MADsIra Weiny
In preparation to support the new OPA MAD Base version, add a base version parameter to ib_create_send_mad and set it to IB_MGMT_BASE_VERSION for current users. Definition of the new base version and it's processing will occur in later patches. Signed-off-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
