vhost: validate virtqueue size

Check the virtqueue size constraints so that invalid values don't cause
bugs later on in the code.  For example, sometimes the virtqueue size is
stored as unsigned int and sometimes as uint16_t, so bad things happen
if it is ever larger than 65535.

vhost: fix message payload union in setting ring address

vhost_user_set_vring_addr() uses the msg->payload.addr union member, not
msg->payload.state.  Luckily the offset of the 'index' field is
identical in both structs, so there was never any buggy behavior.

vhost: clear out unused SCM_RIGHTS file descriptors

The number of file descriptors received is not stored by vhost_user.c.
vhost_user_set_mem_table() assumes that memory.nregions matches the
number of file descriptors received, but nothing guarantees this:

  for (i = 0; i < memory.nregions; i++)
      close(pmsg->fds[i]);

Another questionable code snippet is:

  case VHOST_USER_SET_LOG_FD:
      close(msg.fds[0]);

If not enough file descriptors were received then fds[] contains
uninitialized data from the stack (see read_fd_message()).  This might
cause non-vhost file descriptors to be closed if the uninitialized data
happens to match.

Refactoring vhost_user.c to pass around and check the number of file
descriptors everywhere would make the code more complex.  It is simpler
for read_fd_message() to set unused elements in fds[] to -1.  This way
close(-1) is called and no harm is done.

vhost: avoid enum fields in VhostUserMsg

The VhostUserMsg struct binary representation must match the vhost-user
protocol specification since this struct is read from and written to the
socket.

The VhostUserMsg.request union contains enum fields.  Enum binary
representation is implementation-defined according to the C standard and
it is unportable to make assumptions about the representation:

  6.7.2.2 Enumeration specifiers
  ...
  Each enumerated type shall be compatible with char, a signed integer
  type, or an unsigned integer type. The choice of type is
  implementation-defined, but shall be capable of representing the
  values of all the members of the enumeration.

Additionally, librte_vhost relies on the enum type being unsigned when
validating untrusted inputs:

  if (ret <= 0 || msg.request.master >= VHOST_USER_MAX) {

If msg.request.master is signed then negative values pass this check!

Even if we assume gcc on x86_64 (SysV amd64 ABI) and don't care about
portability, the actual enum constants still affect the final type.  For
example, if we add a negative constant then its type changes to signed
int:

  typedef enum VhostUserRequest {
      ...
      VHOST_USER_INVALID = -1,
  };

This is very fragile and it's unlikely that anyone changing the code
would remember this.  A security hole can be introduced accidentally.

This patch switches VhostUserMsg.request fields to uint32_t to avoid the
portability and potential security issues.

having to special-case cross-building, just check for the presence of

Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>

meter: add configuration profile

This patch adds support for meter configuration profiles.
Benefits: simplified configuration procedure, improved performance.

Q1: What is the configuration profile and why does it make sense?
A1: The configuration profile represents the set of configuration
    parameters for a given meter object, such as the rates and sizes for
    the token buckets. The configuration profile concept makes sense when
    many meter objects share the same configuration, which is the typical
    usage model: thousands of traffic flows are each individually metered
    according to just a few service levels (i.e. profiles).

Q2: How is the configuration profile improving the performance?
A2: The performance improvement is achieved by reducing the memory
    footprint of a meter object, which results in better cache utilization
    for the typical case when large arrays of meter objects are used. The
    internal data structures stored for each meter object contain:
       a) Constant fields: Low level translation of the configuration
          parameters that does not change post-configuration. This is
          really duplicated for all meters that use the same
          configuration. This is the configuration profile data that is
          moved away from the meter object. Current size (implementation
          dependent): srTCM = 32 bytes, trTCM = 32 bytes.
       b) Variable fields: Time stamps and running counters that change
          during the on-going traffic metering process. Current size
          (implementation dependent): srTCM = 24 bytes, trTCM = 32 bytes.
          Therefore, by moving the constant fields to a separate profile
          data structure shared by all the meters with the same
          configuration, the size of the meter object is reduced by ~50%.

net/failsafe: fix Rx interrupt reinstallation

Fail-safe dev_start() operation can be called by both the application
and the hot-plug alarm mechanism.

The installation of Rx interrupt are triggered from dev_start() in any
time it is called while actually the Rx interrupt should be installed
only by the application calls.

So, each plug-in event causes reinstallation which causes memory leak
and spoils the fail-safe Rx interrupt mechanism.

Trigger the Rx interrupt installation only when it does not exist.

net/tap: fix promiscuous rules double insertions

Running testpmd command "port stop all" followed by command "port start
all" may result in a TAP error:
PMD: Kernel refused TC filter rule creation (17): File exists

Root cause analysis: during the execution of "port start all" command
testpmd calls rte_eth_promiscuous_enable() while during the execution
of "port stop all" command testpmd does not call
rte_eth_promiscuous_disable().
As a result the TAP PMD is trying to add tc (traffic control command)
promiscuous rules to the remote netvsc device consecutively. From the
kernel point of view it is seen as an attempt to add the same rule more
than once. In recent kernels (e.g. version 4.13) this attempt is rejected
with a "File exists" error. In less recent kernels (e.g. version 4.4) the
same rule may have been successfully accepted twice, which is undesirable.

In the corrupted code every tc promiscuous rule included a different
handle number parameter. If instead an identical handle number is
used for all tc promiscuous rules - all kernels will reject the second
identical rule with a "File exists" error, which is easy to identify and
to silently ignore.
