2020-06-08vxlan: Fixed checksum caclculation offsetVladimir Isaev1-10/+19
VXLAN uses csum_offload for IPv6 packets. But without gso node we have csum calculated only for inner packet. This patch adds support for outer header csum calculation. Checksum for inner packet should be calculated before interface-output node (for example in vxlan node).

2020-04-15pg: set vnet buffer flags in pg streamsDave Barach1-1/+4
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.

2019-10-03misc: add "maxframe" and "rate" to packet-generator cli.Christian E. Hopps1-2/+2
Allow for setting the maximum number of generated packets to be included in the frame passed to next nodes. This is very important for testing code which may be susceptible to multi-frame vs single-frame bugs (e.g., code that is doing re-ordering where packets may be buffered between frames). Update: - remove redundant packet "rate" option. - reduce n_max_frame to u32 as that's what pulled from the CLI. Type: feature Signed-off-by: Christian E.

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.

2019-05-09add mactime plugin unit / code coverage testsDave Barach1-4/+3
The unit and code coverage tests are boring. The rest of the patch involves test and packet-generator infra cleanups. Teach the "make test-xxx" family of targets to set the api test plugin path correctly, to make "binary-api <api-message-name> <args>" debug CLI commands work correctly in the "make test" environment. Unfortunately involves both the top-level and test Makefiles. Add a minor pg cli feature, a CLI to manually set s->sw_if_index[VLIB_TX]. Consider the case where one configures an interface with both a device-input and an output feature. To test the output feature using the pg, it's necessary to inject packets into the interface output node with both b->sw_if_index[VLIB_TX] and b->sw_if_index[VLIB_RX] set correctly. For example: packet-generator new { name tx limit 15 size 128-128 interface local0 # rx: device input feature not configured on local0 tx-interface loop0 # tx: output node requires b->sw_if_index[VLIB_TX] node loop0-output data { hex 0x01005e7ffffa000dead0000008000102030405060708090a0b0c0d0e0f0102030405 } } Fix a longstanding bug in the packet generator stream setup. Remove kludges which set b->sw_if_index[VLIB_TX] to ~0 [in multiple places] instead of using the stream value s->sw_if_index[VLIB_TX], and setting THAT datum correctly.

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion1-3/+3
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.

2017-04-06Use thread local storage for thread indexDamjan Marion1-2/+2
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-07DHCP Multiple Servers (VPP-602, VPP-605)Neale Ranns1-0/+6
Multiple DHCP (4 and/or 6) servers can be added and removed through multiple calls to the 'set dhcp server' API. All 4/6/ discover/solicit messages will then be replicated to all servers in the list. The expectation is that the servers/system is configured in such a way that this is viable. If VSS information is providied for the clinet VRF which also has multiple servers configured, then the same VSS information is sent to each server. Likewise the source address of packets sent to from VPP to each server is the same. Change-Id: I3287cb084c84b3f612b78bc69cfcb5b9c1f8934d Signed-off-by: Neale Ranns <nranns@cisco.com>
