buildtools: allow pedantic empty pmdinfo

If a driver has no info generated by pmdinfogen,
and if this driver is compiled as pedantic,
then an failure would occur:
drivers/rte_common_mlx5.pmd.c:1: error:
ISO C forbids an empty translation unit [-Werror=pedantic]
Such error is triggered with the new mlx5 common directory.

In order to allow an "empty driver info" compiled in pedantic mode,
the script generating .pmd.c file is modified to add a static string
unconditionnaly.
The minimal generated code is:
static __attribute__((unused)) const char *generator =
"/path/to/dpdk/buildtools/gen-pmdinfo-cfile.sh";

4 years agocryptodev: revert Chacha20-Poly1305 AEAD algorithm

cryptodev: revert Chacha20-Poly1305 AEAD algorithm

API makes think that rte_cryptodev_info_get() cannot return
a value >= 3 (RTE_CRYPTO_AEAD_LIST_END in 19.11).
20.02-rc1 was returning 3 (RTE_CRYPTO_AEAD_CHACHA20_POLY1305).
So the ABI compatibility contract was broken.

It could be solved with some function versioning,
but because a lack of time, the feature is reverted for now.

4 years agodevtools: add ABI checks

devtools: add ABI checks

For normal developers, those checks are disabled.

Enabling them requires a configuration that will trigger the ABI dumps
generation as part of the existing devtools/test-build.sh and
devtools/test-meson-builds.sh scripts.

Those checks are enabled in the CI for the default meson options on x86
and aarch64 so that proposed patches are validated via our CI robot.
A cache of the ABI is stored in travis jobs to avoid rebuilding too
often.

Checks can be informational only, by setting ABI_CHECKS_WARN_ONLY when
breaking the ABI in a future release.

Explicit suppression rules have been added on internal structures
exposed to crypto drivers as the current ABI policy does not apply to
them.
This could be improved in the future by carefully splitting the headers
content with application and driver "users" in mind.

We currently have issues reported for librte_crypto recent changes for
which suppression rules have been added too.

Mellanox glue libraries are explicitly skipped as they are not part of

modify actions, 16 or 8 for each. But in other tables, there is no
such strict limitation. In an IPv6 case, the IP fields modifying

app/test: remove meson dependency on file in /sys

Meson versions 0.52 and 0.53 are being overly smart and detecting the path
"/sys/devices/system/cpu/present" in the call to cat in
app/test/meson.build and then adding it as a dependency to the build
configuration. This causes issues on systems where the timestamp of that
file always returns the current time, since it means that the build.ninja
file is always out of date, and therefore needs to be rebuilt.

We can fix this by just using a simple shell script to return the coremask
appropriately for BSD and Linux, and removing that code logic from meson -
thereby hiding the use of the /sys file.

mempool: remove memory wastage on non-x86

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,

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 eba11e364614 ("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.

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
