2019-07-24api: binary api cleanupDave Barach2-3/+6
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.

2019-02-14Add -fno-common compile optionBenoît Ganne1-1/+1
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

2018-09-12Fix create memif socketEd Warnicke1-16/+0
create interface memif [id <id>] [socket-id <socket-id>] ... Can optionally take a socket-id. You create a socket-id with: create memif socket [id <id>] [filename <path>] Unfortunately, this doesn't work because "create memif" was deprecated. It results in: vpp# create memif socket id 0 filename /run/vpp/test.socket command deprecated. Please use 'create interface memif' instead. This fixes it by clipping out the create memif command entirely. Change-Id: If503758706bf758b6cb46e958200527a5856c600 Signed-off-by: Ed Warnicke <hagbard@gmail.com>

2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-1/+1
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.

In version 1 of the protocol sender was always ring producer and receiver was consumer. In version 2 slave is always producer, and in case of master-to-slave rings, slave is responsible for populating ring with empty buffers. As this is major change, we need to bump version number. In addition, descriptor size is reduced to 16 bytes. This change allows zero-copy-slave operation (to be privided in the separate patch).
