- Log ----------------------------------------------------------------- == OpenDataPlane (1.19.0.1) === Summary of Changes ODP v1.19.0.1 is the first service update for the Tiger Moth release. It incorporates a number of corrections and enhancements that improve the quality and testability of ODP.
==== APIs There are no API changes in this release.
==== DPDK Service Release Sync ODP is now paired with DPDK 17.11.2 for it's DPDK-related support. This is the current service level for the DPDK 17.11 LTS package used by ODP Tiger Moth and incorporates a number of important bug fixes.
=== Implementation Improvements The ODP reference implementation has been improved in a number of areas.
==== GCC 8 Support The GCC 8 series of compilers provides additional warnings about possible string truncation. A few ODP modules were changed to avoid misleading warnings when compiling with this level of GCC.
==== Linking with `libnuma` The `libnuma` library is used for DPDK pktios to provide proper memory allocation on NUMA-aware systems. Linking with this library is improved to avoid extraneous error messages at build time.
==== Packet metadata reorganization Packet metadata is reorganized to reduce the cache footprint used by the ODP reference implementation, resulting in performance improvements.
==== Random split from crypto module The `odp_random_xxx()` family of APIs was moved to a separate module (`odp_random.c`) for modularity and better isolation from planned crypto enhancements.
==== Shmem improvements Unnecessary locking is removed from the `odp_fdserver` module, streamlining operations on shared memory.
==== Timer pools The default number of timer pools supported by the ODP reference implementation has been reduced from 255 to 32. This lower number remains generously adequate for most applications and meaningfully reduces memory footprint, giving better performance.
==== Timer resolution During initialization ODP normally measures timer resolution to set the reported `highest_res_ns`. When such measurement is not able to be performed, this is not limited to 500ns to avoid bounds errors with overly precise resolutions.
=== Validation Improvements The ODP validation test suite has been improved in a number of areas.
==== Crypto validation test The validation test now correctly handles corner cases when the implementation under test fails to process any test packets. It also includes the previously missing `ODP_CIPHER_ALG_AES_CTR` name.
Additionally, since individual implementations indicate which crypto/hash algorithms are supported via the `odp_crypto_capability()` API, the crypto validation test now properly uses this information and only tests those algorithms that the implementation reports as supported. The list of unsupported algorithms is also reported as part of the test results.
==== `odp_sched_pktio` test improvements The number of input/output queues used by this test can now be specified, providing additional controls for test flexibility. In addition, pktout queues are now selected based on input queue rather than worker id, thus ensuring packet order flow is maintained.
Finally, an inactivity timer is added that allows the test to report when packets were handled due to timeout rather than I/O activity.
==== Timer validation test The validation test for the ODP timer APIs has been reorganized to better characterize an implementation's conformance to the ODP Timer API specification. Since implementations can have widely differing timer accuracy levels, particularly when running in virtualized environments, the test also relaxes its bounds checking and enforcement somewhat to better avoid false negative test results.
Additionally, a timer pool create/destroy test was added as this area was not adequately covered previously.
=== Documentation Improvements The `EXTRA_ASCIIDOC_FLAGS` environment variable may now be used to supply additional build flags for Asciidoctor, which can be used to override icons and/or fonts for distribution or other needs.
