The problem occurred when workaround that makes soname two digits
applied. With this change for the ABI version "20.0.1" the experimental
library version become ".so.2001".
After workaround removed in ABI version 21.0, the experimental library
version will become ".so.210".
"2001" is bigger value than "201" although it is a previous version of
the library version, this can break the version comparisons.
To fix this, introducing a temporary sub level versioning for the
experimental libraries, so that minor version comparison will continue
to work.
After change experimental libraries will follow below versioning:
DPDK version ABI version soname library name
------------ ----------- ------ ------------
DPDK 19.11 20.0 .so.0.200 .so.0.200
DPDK 20.02 20.0.1 .so.0.200.1 .so.0.200.1
DPDK 20.05 20.0.2 .so.0.200.2 .so.0.200.2
DPDK 20.11 21.0 .so.0.210 .so.0.210
DPDK 21.02 21.1 .so.0.211 .so.0.211
Note: After workaround removed in DPDK 20.11 and soname switch back to
single digit this patch won't work and needs to be updated.

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.

As per new ABI policy [1], all of the libraries are now versioned using
one global ABI version. Stable libraries use the MAJOR.MINOR ABI
version for their shared objects, while experimental libraries
use the 0.MAJORMINOR convention for their versioning.
Experimental library versioning is managed globally. Changes in this
patch implement the necessary steps to enable that.
The CONFIG_RTE_MAJOR_ABI option was introduced to permit multiple
DPDK versions installed side by side. The problem is now addressed
through the new ABI policy, and thus can be removed.

Which means telemetry no more benefits from --no-as-needed anyway.
Overlinking problems get triggered by the meson generated pkgconfig which

This will overlink <somelibs> and in addition anything that follows

When a component uses either XOPEN_SOURCE or POSIX_C_SOURCE macro
explicitly in its build recipe, it restricts visibility of a non POSIX
features subset, such as IANA protocol numbers (IPPROTO_* macros).
Non standard features are enabled by default for DPDK both for Linux
thanks to _GNU_SOURCE and for FreeBSD thanks to __BSD_VISIBLE. However
using XOPEN_SOURCE or POSIX_(C_)SOURCE in a component causes
__BSD_VISIBLE to be defined to 0 for FreeBSD, causing different feature
sets visibility for Linux and FreeBSD. It restricts from using IPPROTO
macros in public headers, such as rte_ip.h, despite the fact they are
already widely used in sources.
Add __BSD_VISIBLE macro specified unconditionally for FreeBSD targets
which enforces feature sets visibility unification between Linux and
FreeBSD.
Add single -D_GNU_SOURCE to config/meson.build as a project argument
instead of adding separate directive for each project subtree.

The post-install script to symlink the PMDs from their own PMD directory to

Reworking the script to take the relative driver path as parameter removes

As part of the fix, we move the registration of the install script to the

Since we have the version number in a separate file at the root level,
we should not need to duplicate this in rte_version.h too. Best
approach here is to move the macros for specifying the year/month/etc.
parts from the version header file to the build config file - leaving
the other utility macros for e.g. printing the version string, where they
are.
For "make", this is done by having a little bit of awk parse the version
file and pass the results through to the preprocessor for the config
generation stage.
For "meson", this is done by parsing the version and adding it to the
standard dpdk_conf object.
In both cases, we need to append a large number - in this case "99",
previously 16 in original code - to the version number when we want to do
version number comparisons. Without this, the release version e.g. 19.05.0
will compare as less than it's RC's e.g. 19.05.0-rc4. With it, the
comparison is correct as "19.05.0.99 > 19.05.0-rc4.99".

This commit reworks the checks for binutils 2.30 and how
the flags to disable AVX512F are passed to the compiler.
Previously the #define for including AVX512 code was set,
while the -mno-avx512f argument was given to the compiler.
This would cause gcc to correctly refuse to emit AVX512
instructions, but the rte_memcpy code that includes AVX512
optimizations was being added to the build.
The check for binutils check is now moved to x86 as it is
irrelevant for other architectures, and the -mno-avx512f
flag is passed to a march_opts array in meson. As the
-mno-avx512 flag is added earlier in the build, the code
in rte_memcpy is no longer attempted to be compiled.

The root cause is: the hybride compilers add the warning options to the
meson project as project arguments, which apply for both host compiling and
cross compiling. But some options such as '-Wno-format-truncation' are not
supported nor recognized by clang, so they have to be removed from the
project arguments for the host compiler to run smoothily and added back as
cflags for the cross compiler to compile for cross source files.
The fix is remove unrecognized warning options from the meson project
arguments shared by gcc and clang, as add them specifically for gcc or

The strncpy function is error prone for doing "safe" string copies, so

"strlcpy" is a better alternative, since it better conveys the
intention of the programmer, and doesn't suffer from the non-null
terminating behaviour of it's n'ed brethern.
The downside of this function is that it is not available by default
on linux, though standard in the BSD's. It is available on most
distros by installing "libbsd" package.
This patch therefore provides the following in rte_string_fns.h to ensure
that strlcpy is available there:
* for BSD, include string.h as normal
* if RTE_USE_LIBBSD is set, include <bsd/string.h>
* if not set, fallback to snprintf for strlcpy
Using make build system, the RTE_USE_LIBBSD is a hard-coded value to "n",
but when using meson, it's automatically set based on what is available
on the platform.

Any flags added to the project args are automatically added to all builds,
both native and cross-compiled. This is not what we want for the -march
flag as a valid -march for the cross-compile is not valid for pmdinfogen
which is a native-build tool.
Instead we store the march flag as a variable, and add it to the default
cflags for all libs, drivers, examples, etc. This will allow pmdinfogen to
compile successfully in a cross-compilation environment.

The EAL and compat libraries were special-cases in the library build
process, the former because of it's complexity, and the latter because
it only consists of a single header file.
By reworking the EAL meson.build files, we can eliminate the need for it to
be a special case, by having it build up and return the list of sources,
headers, and objects and return those to the higher level build file. This
should also simplify the building of EAL, as we can eliminate a number of
meson.build files that would no longer be needed, and have fewer, but
larger meson.build files (9 now vs 14 previous) - thereby making the logic
easier to follow and items easier to find.
Once done, we can pull eal into the main library loop, with some
modifications to support it. Compat can also be pulled it once we add in a
check to handle the case of an empty sources list.

DPDK has an optional dependency on libnuma, so manage that through the
build system, by dynamically detecting the presence of the needed library
and header files. Since this library is used by both EAL and vhost, check
for the presence at the top level in the config directory.

Since a number of libraries depend on the maths lib, as well as adding it
to the project args, we also need to add it to the pkgconfig file args.

A subset of the dpdk headers are arch-dependent, but have common names
and thus cause a clash in a multiarch installation.
For example, rte_config.h is different for each target.
Add a "include_subdir_arch" option to allow a user to specify a
subdirectory for arch independent headers to fix multiarch support.
