2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-1/+27
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-09-09interface: support configuring RSS steering queuesChenmin Sun1-0/+26
This patch adds the RSS steering queues set interface, and it's implementation in DPDK device: /* Interface to set rss queues of the interface */ typedef clib_error_t *(vnet_interface_rss_queues_set_t) (struct vnet_main_t * vnm, struct vnet_hw_interface_t * hi, clib_bitmap_t *bitmap); This patch also introduces a command line to set the RSS queues: set interface rss queues <interface> <list <queue-list>> To display the rss queues, use "show hardware-interfaces" Below is the example to configure rss queues for interface Gig0: vpp# set interface rss queues Gig0 list 0,2,4-7 vpp# show hardware-interfaces brief Name Idx Link Hardware VirtualFunctionEthernet18/1/0 1 down VirtualFunctionEthernet18/1/0 Link speed: unknown RSS queues: 0 2 4 5 6 7 local0 0 down local0 Link speed: unknown vpp# Users can also configure the rss queues on a dpdk interface in startup.conf: dpdk { dev 0000:18:01.0 { rss-queues 0,2,5-7 } } Type: feature Signed-off-by: Chenmin Sun <chenmin.sun@intel.com> Change-Id: I1835595a1c54016a84eabee9fd62ce137935385d
2020-04-15pg: set vnet buffer flags in pg streamsDave Barach1-0/+28
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

2019-11-12interface: Allow VLAN tag-rewrite on non-sub-interfaces too.Jon Loeliger1-0/+36
This fix was first made in commit fdea5c6a00b74971dbb1b7ec4e25839a871006ca but was subsequently lost in commit 053204ab039d34a990ff0e14c32ce3b294fcce0e Added unit test for setting VTR on a non-sub-interface to help ensure no future regressions of this ability.

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.

2019-05-17Add a debug-CLI leak-checkerDave Barach1-57/+33
leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.

The buffer index allows downstream consumers of these data to easily filter/track single packets as they traverse the forwarding graph. FWIW, the 32-bit buffer index is stored in big endian format. As of this writing, major version = 1, minor version = 0. Nstrings will be either 4 or 5. Here is the current set of protocol hints: typedef enum { VLIB_NODE_PROTO_HINT_NONE = 0, VLIB_NODE_PROTO_HINT_ETHERNET, VLIB_NODE_PROTO_HINT_IP4, VLIB_NODE_PROTO_HINT_IP6, VLIB_NODE_PROTO_HINT_TCP, VLIB_NODE_PROTO_HINT_UDP, VLIB_NODE_N_PROTO_HINTS, } vlib_node_proto_hint_t; Example: VLIB_NODE_PROTO_HINT_IP6 means that the first octet of packet data SHOULD be 0x60, and should begin an ipv6 packet header.
