2019-10-07devices: vhost not reading packets from vringSteven Luong2-0/+25
In a rare event, after the vhost protocol message exchange has finished and the interface had been brought up successfully, the driver MAY still change its mind about the memory regions by sending new memory maps via SET_MEM_TABLE. Upon processing SET_MEM_TABLE, VPP invalidates the old memory regions and the descriptor tables. But it does not re-compute the new descriptor tables based on the new memory maps. Since VPP does not have the descriptor tables, it does not read the packets from the vring. In the normal working case, after SET_MEM_TABLE, the driver follows up with SET_VRING_ADDRESS which VPP computes the descriptor tables. The fix is to stash away the descriptor table addresses from SET_VRING_ADDRESS. Re-compute the new descriptor tables when processing SET_MEM_TABLE if descriptor table addresses are known.

2019-07-23api: binary api cleanupDave Barach4-10/+18
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.

2019-07-23devices: vhost handling VHOST_USER_SET_FEATURESSteven Luong1-0/+1
Some combinations of new qemu (2.11) and old dpdk (16.10) may send VHOST_USER_SET_FEATURES at the end of the protocol exchange which the vhost interface is already declared up and ready. Unfortunately, the process of VHOST_USER_SET_FEATURES will cause the interface to go down. Not sure if it is correct or needed. Because there is no additional messages thereafter, the hardware interface stays down. The fix is to check the interface again at the end of processing VHOST_USER_SET_FEATURES. If it is up and ready, we bring back the hardware interface. Type: fix Change-Id: I490cd03820deacbd8b44d8f2cb38c26349dbe3b2 Signed-off-by: Steven Luong <sluong@cisco.com>

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.
