It +incorporates a number of corrections and enhancements that further 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 17.11.3 for its DPDK-related support. This is the +current service level for the DPDK 17.11 LTS package used by ODP Tiger Moth. + +=== Implementation Improvements +This release incorporates several improvements in the `odp-linux` reference +implementation of ODP. + +==== Enhanced Inlining +ODP supports inlining of functions in embedded environments when ABI +compatibility is not needed. ODP itself now makes use of inlined functions for +all relevant internal use of its APIs, leading to improved performance. + +==== Completion of CRC API Implementation +The `odp_hash_crc_gen64()` API is now properly implemented and appropriate +validation tests added to support it. + +In addition, a streamlined table-based implementation of the basic CRC +functions eliminates the previous dependency on `zlib`. + +==== PktIO-Specific Parsing +To better integrate with DPDK parsing capabilities, ODP packet parsing has +been restructured to operate at the PktIO level. This permits DPDK PktIO types +to exploit the native DPDK packet parser and checksum facilities, leading +to better integration. + +==== PktIO Internal Cleanup and Restructure +The PktIO functions have been streamlined and refactored in a number of ways +to provide better long-term maintainability of these functions. This includes +moving per-PktIO data into individual files rather than sharing a common file, +as well as better placement for I/O statistics. + +==== Checksum Validation Support +Loop PktIO interfaces now add the capability to validate packet L3 and L4 +checksums as part of receive processing. The existing `odp_pktio_capability()` +API now reports that checksum validation is available for these interfaces. + +==== Single Producer / Single Consumer Queue Performance Optimizations +When defining lock free queues that have only a single producer and consumer, +a streamlined implementation offers significant speedup. + +==== Fast PCAPng Packet Capture +Fast pcap capture is now provided in `odp-linux` to capture packets on any +interface. This is enabled via the `--enable-pcapng-support` configuration +option. Once enabled, packets can be captured using a sequence such as: +----- +sudo mkdir /var/run/odp/ +start ODP application that reads/writes to the interface of interest +start the ODP application +sudo dd if=/var/run/odp/<pid>-<ifname>-flow-<queue#> of=~/test.pcap + +cntrl^c to end capture +wireshark ~/test.pcap to view capture +----- + +Interfaces of interest are identified by a string consisting of the +application process ID, the interface name, and the queue number of interest, +if the interface supports multiple queues. + +==== Removal of GPL M4 Macros +A number of autotools/autoconf M4 macros used in configuring `odp-linux` have +been rewritten to avoid potential GPL licensing concerns. These macros are +used only during ODP configuration processing and have no role in ODP +or ODP application use. + +=== Validation Test Improvements +==== Queue Pair Validation Tests +The validation test suite for queue API testing is enhanced to now test +operation on queue pairs properly. This enables the various enqueue/dequeue +modes defined by the ODP specification to be more fully exercised, leading +to improved API conformance. + +==== Scheduling Test Improvements +The scheduling validation tests now better use the various capability APIs to +ensure that implementations are only tested for advertised capabilities. + +=== Crypto Test Improvements +The crypto validation tests now better use the various capability APIs to +ensure that implementations are tested across advertised crypto capabilities. + +=== Performance Test Improvements +==== New Performance Test +A new `odp_queue_perf` test has been added to test plain (non-scheduled) +queue performance in various modes. + +=== Helper Changes +* The `getopt` library calls are no longer used to avoid packaging conflicts +that can arise with this use. There are no changes to helper functionality. +This change simply improves packaging. + +=== Examples Improvements +* The `odp_generator` example adds UDP port range support. + +==== CI Improvements +Numerous changes to Travis integration are added to improve the quality and +reliability of Continuous Integration (CI) testing. + +=== Bug Fixes +==== https://bugs.linaro.org/show_bug.cgi?id=3787%5BBug 3787] +Timeout accuracy breaks down with odd resolution requests + +==== https://bugs.linaro.org/show_bug.cgi?id=3867%5BBug 3867] +timer validation test fails when using 1GB huge pages + +==== https://bugs.linaro.org/show_bug.cgi?id=3879%5BBug 3879] +example/l2fwd_simple fails on some systems when using 1GB huge pages + +=== Unnumbered Bug Fixes +* Corrected the handling of timeout events in the scalable scheduler. +* Fixed IPsec link order to streamline builds. + +=== Known Issues +==== https://bugs.linaro.org/show_bug.cgi?id=3774%5BBug 3774] +Shmem validation test runs indefinitely with 1GB huge pages + == OpenDataPlane (1.19.0.1) === Summary of Changes ODP v1.19.0.1 is the first service update for the Tiger Moth release.
