e53084d84b vhost: log socket path on adding connection
Add log print of socket path in vhost_user_add_connection.
It's useful when adding a mass of socket connections,
because the information of every connection is clearer.

451dc0fad8 vhost: fix crash on port deletion
The rte_vhost_driver_unregister() and vhost_user_read_cb()
can be called at the same time by 2 threads.
when memory of vsocket is freed in rte_vhost_driver_unregister(),
the invalid memory of vsocket is accessed in vhost_user_read_cb().
It's a bug of both mode for vhost as server or client.

E.g., vhostuser port is created as server.
Thread1 calls rte_vhost_driver_unregister().
Before the listen fd is deleted from poll waiting fds,
"vhost-events" thread then calls vhost_user_server_new_connection(),
then a new conn fd is added in fdset when trying to reconnect.
"vhost-events" thread then calls vhost_user_read_cb() and
accesses invalid memory of socket while thread1 frees the memory of
vsocket.

E.g., vhostuser port is created as client.
Thread1 calls rte_vhost_driver_unregister().
Before vsocket of reconn is deleted from reconn list,
"vhost_reconn" thread then calls vhost_user_add_connection()
then a new conn fd is added in fdset when trying to reconnect.
"vhost-events" thread then calls vhost_user_read_cb() and
accesses invalid memory of socket while thread1 frees the memory of
vsocket.

The fix is to move the "fdset_try_del" in front of free memory of conn,
then avoid the race condition.

The core trace is:
Program terminated with signal 11, Segmentation fault.

abeb865255 vhost: remove copy threshold for async path
Copy threshold has been introduced in async vhost data
path to select the appropriate copy engine to do copies
for higher efficiency.

However, it may cause packets ordering issues and also
introduces performance unpredictability.

Therefore, this patch removes copy threshold support in

MAC-I = f(key, varShortMAC-I, count, bearer, direction).

d2a66ad794 bus: add device arguments name parsing
For device probe and iterator, devargs name was key information,
parsed by rte_devargs_parse. In legacy parser, devargs name was
extracted after bus name:
  bus:name,kv_arguments,,,
Example:
  pci:83:00.0,arguments,...
  vdev:pcap0,...

To be compatible with legacy parser, this patch introduces new
bus driver API devargs_parse to parse devargs and update devargs name.
If devargs_parse not implemented by bus driver, the new syntax parser
rte_devargs_layers_parse default will resolve devargs name from bus's
"name" argument.

Different bus driver might choose different keys from arguments with
unified format. The PCI bus implementation fills the devargs name with
the "addr" argument, example:
 -a bus=pci,addr=83:00.0/class=eth/driver=mlx5,...
    name: 0000:03:00.0
 -a bus=vdev,name=pcap0/class=eth/driver=pcap,...

A temporary pointer is set before the free of cryptodev->data,

The first argument to rte_bsf32_safe was incorrectly declared as

function rte_bsf32 only accepts 32 bit values. This was a mistake
introduced when the safe version was added and probably cause
by copy/paste from the 64 bit version.

The bug passed silently under the radar until some other code was
built with -Wall and -Wextra in C++ and C++ complains about the
missing cast.

Yes, this is a API signature change, but the original code was wrong.
It is an inline so not an ABI change.

92ed77dce6 vhost: fix packed ring index wrapping
Unlike split ring, packed ring does not mandate the ring size
to be a power of 2. So we have to use a modulo operation when
wrapping ring index.

2e3f1ab0d8 vhost: fix async packed ring batch datapath
We assume that in the sync path, if there is no buffer wrap in the
avail descriptors fetched in a batch, there is no buffer wrap in the
used descriptors which need to be written back in this batch, but
this assumption is wrong in the async path since there are inflight
descriptors which are processed by the DMA device.

This patch refactors the batch copy code and adds used ring buffer
wrap check as a batch copy condition to fix this issue.

8d2c1260af vhost: fix index overflow for packed ring in async vhost
We introduced some new indexes in packed ring of async vhost. They
will eventually overflow and lead to errors if the ring size is not
a power of 2. This patch is to check and keep these indexes within a
reasonable range.

706ba48665 vhost: check header for legacy dequeue offload
When parsing the virtio net header and packet header for dequeue offload,
we need to perform sanity check on the packet header to ensure:
  - No out-of-boundary memory access.
  - The packet header and virtio_net header are valid and aligned.

de8606bf73 distributor: fix 128-bit write alignment
When the distributor sample app is built as a 32-bit app,
the data buffer passed to find_match_vec can be unaligned,
causing a segmentation fault due to writing a 128-bit value
using _mm_store_si128().  128-bit align the data being
passed in so this does not happen.

10eaf41d70 ethdev: keep count of representor ranges in API
In its current state, the API can overflow the user-passed buffer if a new
representor range appears between function calls.

In order to solve this problem, augment the representor info structure with
the numbers of allocated and initialized ranges. This way the users of this
structure can be sure they will not overrun the buffer.
