It incorporates final +implementation changes and bug fixes and completes the Tiger Moth ODP +development cycle. + +==== APIs +No functional changes for this release. The Tiger Moth API was frozen in ODP +v1.18.0.0. + +===== API Documentation Update +The specification for the `odp_packet_l4_chksum_status()` API has been +clarified to reflect that in IPv4 UDP checksums are optional. As a result, a +zero (nonexistent) checksum will be reported as `ODP_PACKET_CHKSUM_OK`. + +==== C++ Test Improvements +The {cpp} test included in the ODP validation suite now uses `cout` instead +of `printf()` to ensure that {cpp} is being used to compile it. + +==== Queue and Scheduler Configuration +For the ODP Reference Implementation, The `config/odp-linux-generic.conf` file +is extended with sections to control the default and maximum sizes for basic +queues, and the priority spread used by the scheduler for scheduled queues. + +The configuration file is a template named `platform/odp-$platform.conf` so +this can be easily inherited by other ODP implementations. + +==== Runtime Default `config` File Read Order Improvements +For the ODP Reference Implementation, the default values of the +application-provided `config` file (if used) override the values provided by +the built-in `config/odp-linux-generic.conf` file. + +=== Implementation Improvements +The `odp-linux` reference implementation is improved in a number of areas: + +==== Netmap Ring Configuration for VALE +PktIO netmap support now uses the ODP config file to allow rings used for VALE +processing to be specified. The supplied defaults provide optimal performance +in typical settings. + +==== AES-XCBC-MAC and SHA384-HMAC +These crypto/authentication algorithms are now implemented. + +==== Packet Checksum Validation and Insertion +Proper packet checksum validation and insertion, in conformance with the +relevant ODP APIs, is now provided. + +=== Dependency Changes + +==== DPDK 17.11 Support +The Tiger Moth LTS release is synchronized with the most recent DPDK LTS +release for DPDK pktio support. + +==== Removal of dependency on `xxd` package. +This dependency is removed. The Reference Implementation build tools now use +the standard `od` tool rather than the optional `xxd` package. + +=== Performance Tests + +==== `odp_sched_pktio` +A new test has been added to test the performance of PktIO operations in +scheduled mode. Scheduled PktIO is inherently more scalable and simpler from +an application standpoint than direct (polled) I/O, but depending on the +efficiency of the scheduler implementation can incur additional levels of +overhead. This test can give insight into a given platform's scheduler +efficiency. For the `odp-linux` reference implementation, this test has shown +scheduled I/O to be within 10% of rates achievable via direct I/O, meaning +that for many applications the simplicity and scalability of the event model +is preferable. + +==== `odp_ipsec` +A new test has been added that measures outbound (TX) IPsec performance with +a variety of cipher and authentication algorithms. + +=== Example Changes + +==== `l2fwd` Example +The `README` file associated with this example has been clarified to explain +that this example is a throughput test and as a result does not preserve +packet order under all conditions. + +=== Bug Fixes +==== https://bugs.linaro.org/show_bug.cgi?id=3611%5BBug 3611] +ODP linux-generic fails on AArch64 in non-ABI-compat mode. + +==== https://bugs.linaro.org/show_bug.cgi?id=3657%5BBug 3657] +PktIO does not work with Mellanox Interfaces + +==== https://bugs.linaro.org/show_bug.cgi?id=3685%5BBug 3685] +RX UDP checksum offload drops valid UDP packets with Niantic + +==== https://bugs.linaro.org/show_bug.cgi?id=3686%5BBug 3686] +IP header checksum not inserted if L4 offset not set + +==== https://bugs.linaro.org/show_bug.cgi?id=3690%5BBug 3690] +fdserver process interferes with signal handling + +==== https://bugs.linaro.org/show_bug.cgi?id=3736%5BBug 3736] +return value not checked for some fdserver interface functions + +=== Known Issues + +==== https://bugs.linaro.org/show_bug.cgi?id=2988%5BBug 2988] +ODP exposes symbols outside of odp*/_odp* namespace + == OpenDataPlane (1.18.0.1) === Summary of Changes ODP v1.18.0.1 is a fix level for Tiger Moth Release Candidate 2 (RC 2).
