3f2d6766e3 mempool: remove memory wastage on non-x86
The existing optimize_object_size() function address the memory object
alignment constraint on x86 for better performance.

Different (micro) architecture may have different memory alignment
constraint for better performance and it not the same as the existing
optimize_object_size().

Some use, XOR(kind of CRC) scheme to enable DRAM channel distribution
based on the address and some may have a different formula.

Introducing arch_mem_object_align() function to abstract
the difference between different (micro) architectures to avoid
wasting memory for mempool object alignment for the architecture
that it is not required to do so.

Details on the amount of memory saving:

Currently, arm64 based architectures use the default (nchan=4,
nrank=1). The worst case is for an object whose size (including mempool
header) is 2 cache lines, where it is optimized to 3 cache lines (+50%).

Examples for cache lines size = 64:
  orig     optimized
  64    -> 64           +0%
  128   -> 192          +50%
  192   -> 192          +0%
  256   -> 320          +25%
  320   -> 320          +0%
  384   -> 448          +16%
  ...
  2304  -> 2368         +2.7%  (~mbuf size)

43503c59ad mempool: fix populate with small virtual chunks
To populate a mempool with a virtual area, the mempool code calls
rte_mempool_populate_iova() for each iova-contiguous area. It happens
(rarely) that this area is too small to store one object. In this case,
rte_mempool_populate_iova() returns an error, which is forwarded by
rte_mempool_populate_virt().

This case should not throw an error in rte_mempool_populate_virt().
Instead, the area that is too small should just be ignored.

To fix this issue, change the return value of
rte_mempool_populate_iova() to 0 when no object can be populated,
so it can be ignored by the caller. As this would be an API/ABI change,
only do this modification internally for now.

3a3d0c75b4 mempool: fix slow allocation of large pools
When allocating a mempool which is larger than the largest
available area, it can take a lot of time:

a- the mempool calculate the required memory size, and tries
   to allocate it, it fails
b- then it tries to allocate the largest available area (this
   does not request new huge pages)
c- add this zone to the mempool, this triggers the allocation
   of a mem hdr, which request a new huge page
d- back to a- until mempool is populated or until there is no
   more memory

This can take a lot of time to finally fail (several minutes): in step
a- it takes all available hugepages on the system, then release them
after it fails.

The problem appeared with commit eba11e3646 ("mempool: reduce wasted
space on populate"), because smaller chunks are now allowed. Previously,
it had to be at least one page size, which is not the case in step b-.

To fix this, implement our own way to allocate the largest available
area instead of using the feature from memzone: if an allocation fails,
try to divide the size by 2 and retry. When the requested size falls
below min_chunk_size, stop and return an error.

725e515ed1 ethdev: allow multiple security sessions to use flow rule
The rte_security API which enables inline protocol/crypto feature
mandates that for every security session an rte_flow is created. This
would internally translate to a rule in the hardware which would do
packet classification.

In rte_security, one SA would be one security session. And if an rte_flow
need to be created for every session, the number of SAs supported by an
inline implementation would be limited by the number of rte_flows the
PMD would be able to support.

If the fields SPI & IP addresses are allowed to be a range, then this
limitation can be overcome. Multiple flows will be able to use one rule
for SECURITY processing. In this case, the security session provided as
conf would be NULL.

Application should do an rte_flow_validate() to make sure the flow is
supported on the PMD.

5efb18e85f vhost: fix deadlock on port deletion
If the vhost-user application (e.g. OVS) deletes the vhost-user
port while Qemu sends a vhost-user request, a deadlock can
happen if the request handler tries to acquire vhost-user's
global mutex, which is also locked by the vhost-user port
deletion API (rte_vhost_driver_unregister).

This patch prevents the deadlock by making
rte_vhost_driver_unregister() to release the mutex and try
again if a request is being handled to give a chance to
the request handler to complete.

74f45f872c vhost: add dynamic logging system
Currently there are a couple of limitations on the logging system: Most
of the logs are compiled out and both datapath and controlpath logs
share the same loglevel.

This patch tries to help fix that situation by:
- Splitting control plane and data plane logs
- Making control plane logs dynamic while keeping data plane logs
  compiled out by default for log levels lower than the INFO.

As a result, two macros are introduced:
- VHOST_LOG_CONFIG(LEVEL, ...): Config path logging. Level can be
  dynamically controlled by "lib.vhost.config"

- VHOST_LOG_DATA(LEVEL, ...): Data path logging. Level can be
  dynamically controlled by "lib.vhost.data". Every log macro with a
  level lower than RTE_LOG_DP_LEVEL (which defaults to RTE_LOG_INFO)
  will be compiled out.

input parameter.  Almost all instances of the service_valid call are
inside a for() loop that prevents excessive walks, but some of the
public APIs don't bounds check and will pass invalid arguments.

Prevent this by using SERVICE_GET_OR_ERR_RET where it makes sense,
and adding a bounds check to one service_valid() use.

30a0df64aa test/common: fix log2 check
We recently started to get random failures on the common_autotest ut with
clang on Ubuntu 16.04.6.

Example: https://travis-ci.com/DPDK/dpdk/jobs/263177424

Wrong rte_log2_u64(0) val 0, expected ffffffff
Test Failed

The ut passes 0 to log2() to get an expected value.

Quoting log2 / log(3) manual:
If x is zero, then a pole error occurs, and the functions return
-HUGE_VAL, -HUGE_VALF, or -HUGE_VALL, respectively.

rte_log2_uXX helpers handle 0 as a special value and return 0.
Let's have dedicated tests for this case.

f26c2b39b2 build: fix soname info for 19.11 compatibility
The soname for each stable ABI version should be just the ABI version major
number without the minor number. Unfortunately both major and minor were
used causing version 20.1 to be incompatible with 20.0.

This patch fixes the issue by switching from 2-part to 3-part ABI version
numbers so that we can keep 20.0 as soname and using the final digits to
identify the 20.x releases which are ABI compatible. This requires changes
to both make and meson builds to handle the three-digit version and shrink
it to 2-digit for soname.

The final fix needed in this patch is to adjust the library version number
for the ethtool example library, which needs to be upped to 2-digits, as
external libraries using the DPDK build system also use the logic in this
file.

Valgrind reports that eal interrupt thread is calling epoll_ctl

This is a false positive, because the kernel is not going to care about

20bbb9e045 ethdev: limit maximum number of queues
A buffer overflow happens in testpmd with some drivers
since the queue arrays are limited to RTE_MAX_QUEUES_PER_PORT.

The advertised capabilities of mlx4, mlx5 and softnic
for the number of queues were the maximum number: UINT16_MAX.
They must be limited by the configured RTE_MAX_QUEUES_PER_PORT
that applications expect to be respected.

The limitation is applied at ethdev level (function rte_eth_dev_info_get),
in order to force the configured limit for all drivers.

64edb05e29 ethdev: fix item expansion for RSS flow
When the last item in flow pattern includes "next protocol" field which
is relevant for RSS flow expansion, a new item is added to the pattern
according to the "next protocol" field. This field is called missed
field.

The missed field wrongly was not initialized what caused to some of the
flow item fields to contain garbage values.

As a result, the PMDs internal flow engine may crash.

For example, the spec value may include garbage pointer and to cause
crash.

Initialize the missed field with zeroes.
