2017-09-27IB/hfi1: Add a safe wrapper for _rcd_get_by_indexMichael J. Ruhl5-5/+28
hfi1_rcd_get_by_index assumes that the given index is in the correct range. In most cases this is correct because the index is bounded by a loop. For these cases, adding a range check to the function is redundant. For the use case that is not bounded by the loop range, a _safe wrapper function is needed to validate the index before accessing the rcd array. Add a _safe wrapper to _get_by_index to validate the index range. Update appropriate call sites with the new _safe function. Reviewed-by: Ira Weiny <ira.weiny@intel.com> Signed-off-by: Michael J.

2017-09-27IB/hfi1: Extend input hdr tracing for packet typeMike Marciniszyn4-44/+44
The etype field from the rhf can have more values than just IB and BYPASS. Extend the current tracing to report a symbolic for the etype field for non-bypass packets. Bypass packets will continue to report the l2. As part of this fix the etype and the l2 are added to the tracing struct and are available for trigger and filter operations.

2017-09-27IB/hfi1: Unsuccessful PCIe caps tuning should not fail driver loadHarish Chegondi1-29/+21
Failure to tune PCIe capabilities should not fail driver load. This can cause the driver load to fail on systems with any of the following: 1. HFI's parent is not root. Example: HFI card is behind a PCIe bridge. 2. HFI's parent is not PCI Express capable. In these situations, failure to tune PCIe capabilities should be logged in the system message logs but not cause the driver load to fail. This patch also ensures pcie capability word DevCtl is written only after a successful read and the capability tuning process continues even if read/write of the pcie capability word DevCtl fails.

2017-09-27Revert "IB/ipoib: Update broadcast object if PKey value was changed in index 0"Alex Estrin1-13/+0
commit 9a9b8112699d will cause core to fail UD QP from being destroyed on ipoib unload, therefore cause resources leakage. On pkey change event above patch modifies mgid before calling underlying driver to detach it from QP. Drivers' detach_mcast() will fail to find modified mgid it was never given to attach in a first place. Core qp->usecnt will never go down, so ib_destroy_qp() will fail. IPoIB driver actually does take care of new broadcast mgid based on new pkey by destroying an old mcast object in ipoib_mcast_dev_flush()) .... if (priv->broadcast) { rb_erase(&priv->broadcast->rb_node, &priv->multicast_tree); list_add_tail(&priv->broadcast->list, &remove_list); priv->broadcast = NULL; } ... then in restarted ipoib_macst_join_task() creating a new broadcast mcast object, sending join request and on completion tells the driver to attach to reinitialized QP: ... if (!priv->broadcast) { ... broadcast = ipoib_mcast_alloc(dev, 0); ... memcpy(broadcast->mcmember.mgid.raw, priv->dev->broadcast + 4, sizeof (union ib_gid)); priv->broadcast = broadcast; ...

After changing INIT_UDATA_BUF_OR_NULL() to an inline function, this does the same change to INIT_UDATA for consistency. I'm keeping it separate as this part is much larger and we wouldn't want to backport this to stable kernels if we ever want to address the gcc warnings by backporting the first patch. Again, using an inline function gives us better type safety here among other issues with macros.
