7 years agovhost: add reconnect ability
Yuanhan Liu [Thu, 12 May 2016 23:14:19 +0000 (07:14 +0800)]
vhost: add reconnect ability

Allow reconnecting on failure by default when:

- DPDK app starts first and QEMU (as the server) is not started yet.
  Without reconnecting, DPDK app would simply fail on vhost-user
  registration.

- QEMU restarts, say due to OS reboot.
  Without reconnecting, you can't re-establish the connection without
  restarting DPDK app.

This patch make it work well for both above cases. It simply creates
a new thread, and keep trying calling "connect()", until it succeeds.

The reconnect could be disabled when RTE_VHOST_USER_NO_RECONNECT flag
is set.

The rest is straingfoward then: allocate a unix socket, and
bind/listen for server, connect for client.

vhost: rename structs for enabling client mode

DPDK vhost-user just acts as server so far, so, using a struct named
as "vhost_server" is okay. However, if we add client mode, it doesn't

There was no obvious wrong about "connfd_ctx", but I think it's obviously
better to rename it to "vhost_user_connection", as it does represent
a connection, a connection between the backend (DPDK) and the frontend

Reshma Pattan [Wed, 15 Jun 2016 14:06:22 +0000 (15:06 +0100)]
pdump: add new library for packet capture

The librte_pdump library provides a framework for
packet capturing in dpdk. The library provides set of
APIs to initialize the packet capture framework, to
enable or disable the packet capture, and to uninitialize
it.

The librte_pdump library works on a client/server model.
The server is responsible for enabling or disabling the
packet capture and the clients are responsible
for requesting the enabling or disabling of the packet
capture.

Enabling APIs are supported with port, queue, ring and
mempool parameters. Applications should pass on this information
to get the packets from the dpdk ports.

For enabling requests from applications, library creates the client
request containing the mempool, ring, port and queue information and
sends the request to the server. After receiving the request, server
registers the Rx and Tx callbacks for all the port and queues.
After the callbacks registration, registered callbacks will get the
Rx and Tx packets. Packets then will be copied to the new mbufs that
are allocated from the user passed mempool. These new mbufs then will
be enqueued to the application passed ring. Applications need to dequeue
the mbufs from the rings and direct them to the devices like
pcap vdev for viewing the packets outside of the dpdk
using the packet capture tools.

For disabling requests, library creates the client request containing
the port and queue information and sends the request to the server.
After receiving the request, server removes the Rx and Tx callback
for all the port and queues.

This patch removes constraints in rxq handling when multiqueue is enabled

Current testpmd forces a dedicated core for each rxq, some rxqs may be
ignored when core number is less than rxq number, and that causes confusion
and inconvenience.

One example: an engineer was doing multiqueue test, there're 2
ports in guest each with 4 queues, and testpmd was used as the forwarding
engine in guest, as usual he used 1 core for forwarding, as a results he
only saw traffic from port 0 queue 0 to port 1 queue 0, then a lot of
emails and quite some time are spent to root cause it, and of course it's
caused by this unreasonable testpmd behavior.

Moreover, even if we understand this behavior, if we want to test the
above case, we still need 8 cores for a single guest to poll all the
rxqs, obviously this is too expensive.
