2019-08-27rdma: fix pending packets check on txBenoît Ganne1-1/+1
Fix coverity CID 203636: Control flow issues (NO_EFFECT). This greater-than-or-equal-to-zero comparison of an unsigned value is always true. "n_left_from >= 0U".

2019-08-06rdma: fix double-free in rdma-txBenoît Ganne2-9/+10
In case of tx success after multiple retries, the last buffers to be enqueued will be both enqueued for tx and freed. Type: fix Fixes: 211ef2eb24 Change-Id: I57d218cff58b74c1f3d6dc5722624327f0821758 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-07-23api: binary api cleanupDave Barach1-1/+1
Multiple API message handlers call vnet_get_sup_hw_interface(...) without checking the inbound sw_if_index. This can cause a pool_elt_at_index ASSERT in a debug image, and major disorder in a production image. Given that a number of places are coded as follows, add an "api_visible_or_null" variant of vnet_get_sup_hw_interface, which returns NULL given an invalid sw_if_index, or a hidden sw interface: - hw = vnet_get_sup_hw_interface (vnm, sw_if_index); + hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index); if (hw == NULL || memif_device_class.index != hw->dev_class_index) return clib_error_return (0, "not a memif interface"); Rename two existing xxx_safe functions -> xxx_or_null to make it obvious what they return.

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz1-1/+1
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

2019-05-24rdma: add support for promiscuous modeBenoît Ganne2-71/+145
rdma interfaces filter packets per MAC by default to share the physical interface between multiple users (eg. VPP and Linux). When configured in promiscuous mode, all packets will go to this interface, regardless of the MAC. All other interface will not receive anymore packet while it is in promiscuous mode. Promiscuous mode is needed (and automatically turned on) for L2 path (l2patch, xconnect, bridge...).

2019-03-28Add RDMA ibverb driver pluginBenoît Ganne8-0/+1401
RDMA ibverb is a userspace API to efficiently rx/tx packets. This is an initial, unoptimized driver targeting Mellanox cards. Next steps should include batching, multiqueue and additional cards. Change-Id: I0309c7a543f75f2f9317eaf63ca502ac7a093ef9 Signed-off-by: Benoît Ganne <bganne@cisco.com>
