2021-01-20memif: fix vpp to go link up immediately on admin upEd Warnicke1-16/+0
Type: improvement Previously, memif would check every 3 seconds to see if an interface had gone admin up. Now it does as soon as admin up occurs. Signed-off-by: Ed Warnicke <hagbard@gmail.com> Change-Id: I808699cd5980fa162c34ac977f43d00ed6b67115 Signed-off-by: Ed Warnicke <hagbard@gmail.com>

Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-08-13Multiarch handling in different constructor macrosDamjan Marion1-11/+8
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

2018-03-22memif: version 2Damjan Marion1-107/+158
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).

2018-01-29memif: Add new API calls to manage memif socket names.Jon Loeliger1-1/+3
New API calls and corresponding CLI commands allow the user to manage the socket filenames for memif connections using: vppctl# create memif id <u32> filename <socket-filename> vppctl# delete memif id <u32> and then referencing it later in a memif interface: vppctl# create memif <u32> socket-id <id> mode <mode> <master|slave> ... Corresponding VAT cli entries have also been added. The default memif socket file at id 0 are still always present. The existing memif create/delete CLI commands have been slightly altered into the new syntax: vppctl# create interface memif ... vppctl# delete interface memif ...

2018-01-09memif: fix coverity divide by zeroSteven1-0/+1
Coverity complains about divide by zero if tx_queues gets the value of 0 from the macro vec_len(). While we don't anticipate such condition to happen, programming errors may exist. To defend against divide by zero, crash and burn if tx_queues gets a value of 0. Change-Id: I65e014c07e9d4adfe119d5b373b5dc24cb818a03 Signed-off-by: Steven <sluong@cisco.com>

2017-09-08memif: fix coverity warnings as of 9/7Steven1-2/+12
1. coverity complains about "buffer not null terminated" for strncpy because we pass the size of the destination to the call which is equal to the true size of the destination. We subtract 1 for the size to accommodate the null like all other places are already doing it. 2. Add a check to tx_queues in memif_interface_tx_inline to avoid "divide by zero". 3. To avoid null pointer dereference in memif_create_if, change the goto done rather than goto error and spit a more meaningful error rather than silent about it. 4. Shuffle a line to avoid "check after use" in vl_api_memif_delete_t_handler. Change-Id: Icba7ecd5362c012a48ac35795d31aab356617420 Signed-off-by: Steven <sluong@cisco.com>

2017-06-16memif: jumbo frames supportSteven1-39/+71
Current memif interface supports frame size up to 2048. This patch is to enhance memif to support jumbo frames. On tx (writing buffers to the ring), keep reading the next buffer in vlib when the flag VLIB_BUFFER_NEXT_PRESENT and merge it to the same ring entry. Use descriptor chaining if the buffer is not big enough. On rx (reading buffers from the ring), if the packet is greater than 2048, create multiple vlib buffers, chained with the VLIB_BUFFER_NEXT_PRESENT. Testing: Because the ping command provided by VPP does not support jumbo frames, I have to use linux ping. Here is the set up that I use for testing. VM1 --- vhost ---- VPP1 --- memif --- VPP2 --- vhost --- VM2 Create vhost-user interfaces between VM1 and VPP1 and between VPP2 and VM2 VM configuration: Set the interface mtu on the VM, e.g 9216 to support jumbo frames. create static route and static arp on VM1 to VM2 and vice versa. Use iperf3 or ping -s 8000 from VM1 to VM2 or vice versa. Sample run sluong@ubuntu:~$ ping 131.1.1.1 -c1 -s 8000 ping 131.1.1.1 -c1 -s 8000 PING 131.1.1.1 (131.1.1.1) 8000(8028) bytes of data. 8008 bytes from 131.1.1.1: icmp_seq=1 ttl=62 time=0.835 ms --- 131.1.1.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.835/0.835/0.835/0.000 ms sluong@ubuntu:~$ DBGvpp# sh interface memif0 Name Idx State Counter Count memif0 1 up rx packets 1 rx bytes 8042 tx packets 1 tx bytes 8042 ip4 1 DBGvpp# Change-Id: I469bece3d45a790dceaee1d6a8e976bd018feee2 Signed-off-by: Steven <sluong@cisco.com>

- Add rx-queues and tx-queues option to the create memif CLI - Add vlib_worker_thread_barrier_sync () to memif_conn_fd_read_ready () as the latter function may disconnect the ring and clean up the shared memory. - On transmit, write the rid (queue number) to the socket. - On receive, read the rid and trigger the interrupt for the corresponding thread.
