- Log ----------------------------------------------------------------- == opendataplane (1.15.0.0) === new features odp v1.15.0.0 continues the preview of tiger moth, introducing new apis and extensions, as well as numerous bug fixes and functional improvements.

==== deprecation framework to permit smoother evolution of the odp api specification, a deprecation framework is introduced to permit controlled deprecation.

when an odp api or defined struct parameter is deprecated, odp validation tests will be updated to no longer use that api and instead use the replacement api. by default, attempts to compile with the older api/feature will fail and applications wishing to move to the new odp release should be updated to use the replacement api. to permit evaluation of new odp releases in advance of such updating, however, odp supports the `configure` option `--enable-deprecated`, which makes the obsolete apis visible again.

this feature will be used on a case-by-case basis and documented in the release notes for each release that introduces replacement api(s). in general the deprecated forms will not be maintained for more than a single release cycle. after that they will no longer be present in the api specification and the replacement forms must be used to compile with that level of the api specification.

==== apis a number of new and refined apis are introduced in crypto, packet parsing, and queue configuration:

===== crypto enhancements the odp crypto apis receive several enhancements in this release:

====== new authentication algorithms additional enumerations added for hmac-sha-1 and hmac-sha-512 authentication.

====== deprecated cipher/authentication algorithms the following cipher/authentication algorithms have been deprecated in favor of newer replacement algorithms:

* `odp_cipher_alg_aes128_cbc` is replaced by `odp_cipher_alg_aes_cbc` * `odp_cipher_alg_aes128_gcm` is replaced by `odp_cipher_alg_aes_gcm` * `odp_auth_alg_md5_96` is replaced by `odp_auth_alg_md5_hmac` * `odp_auth_alg_sha256_128` is replaced by `odp_auth_alg_sha256_hmac` * `odp_auth_alg_aes128_gcm1 is replaced by `odp_auth_alg_aes_gcm`

====== deprecated name for crypto parameter struct `odp_crypto_op_params_t` is deprecated in favor of `odp_crypto_op_param_t` for consistency with other odp `param` structs.

====== digest length session parameter `odp_crypto_session_param_t` adds the field `auth_digest_len` to permit specification of the authentication digest length to be used for this session. the `odp_crypto_auth_capability()` api returns the list of supported digest lengths.

====== additional authentication data (aad) the `odp_crypto_op_param_t` struct adds an optional pointer and length for aad information. this allows applications to specify aad information from the list of supported lengths provided by `odp_crypto_auth_capability()`.

===== packet range data the former `odp_crypto_data_range_t` type is deprecated and renamed to `odp_packet_data_range_t` since it can be used to specify ranges for other than crypto purposes.

===== parser configuration applications may now specify the maximum packet layer of interest. for example, a router may not care about anything beyond iso layer 3 in packets. this can be used by odp implementations to control the depth of packet parsing needed by the application and may allow greater efficiency, especially in software implementations.

this is controlled by a new `odp_pktio_parser_layer_t` enum that is part of the new `odp_pktio_parser_config_t` struct that is added to the `odp_pktio_config_t` struct used by the `odp_pktio_config()` api. the supported parser layers are also returned in this struct as part of the `odp_pktio_capability_t` struct returned by the `odp_pktio_capability()` api.

===== queue size parameter the `odp_queue_capability_t` struct returned by the `odp_queue_capability()` api is enhanced as follows: * the `max_queues` field is now defined to return the maximum number of event queues of any type. * new sub-structs (`plain` and `sched`) are added that detail the `max_num` of queues of that type supported as well as the new field `max_size` that specifies the maximum number of elements that each queue of this type can store. a value of zero for `max_num` indicates no fixed limit.

in addition, the `odp_queue_param_t` passed to `odp_queue_create()` now adds a `size` field to allow applications to specify the minimum number of events that this queue should be able to store. a value of zero specified requests that the implementation default limits be used.

the odp examples have been updated to show this configuration, for example, the `l2fwd_simple` example does layer 2 forwarding and hence doesn't need packets to be parsed beyond layer 2. so prior to opening an interface via `odp_pktio_open()` the configuration processing now includes code of the form: [source,c] ----- odp_pktio_config_init(&config); config.parser.layer = odp_pktio_parser_layer_l2; odp_pktio_config(pktio, &config); ----- this serves as a hint to the odp implementation that parsing beyond layer 2 is not required on this interface.

===== removal of `odp_time_to_u64()` api the `odp_time_to_u64()` api is removed without deprecation in this release. this is redundant since the `odp_time_to_ns()` api already returns a `uint64_t` value for `odp_time_t` and can be used for the same purpose.

===== new `odp_sys_info_print()` api for debugging / diagnostic use, the `odp_sys_info_print()` api is added. this prints implementation defined information about the system and odp environment and may contain information about cpus, memory, and other hardware configuration.

=== helpers ==== linux helpers odp helper functions fall into two categories: system-independent, and those that rely on linux. for backwards compatibility, these have been reorganized into a new `helper/linux` directory that is installed only when the `--enable-helper-linux` `configure` option is specified.

=== `odp-linux` performance ==== scheduler improvements the default scheduler is streamlined by using precomputed weight tables and separated priority queues for different scheduling groups. this improves both latency and scalability.

also included in this change, the default number of scheduling groups is lowered from 256 to 32, which experience has shown is sufficient for most applications.

the scheduler fairness checks are also enhanced to avoid low priority event starvation if `config_burst_size` is set to 1.

=== `odp_linux` crypto improvements * errors in implicit packet copy operations performed during crypto operation are now handled properly. * if `odp_crypto_session_create()` fails, proper cleanup is now performed to avoid memory leaks. * the auth digest len is now used when calculating hmacs, and full-length digests are now added to supported sha capabilities. * numerous crypto functions have been rewritten to use the openssl `evp_` functions for improved efficiency and accuracy.

=== `odp-linux` packet improvements * the packet parser now recognizes icmpv6 packets in addition to icmpv4.

=== `odp-linux` pktio improvements * the `ethtool` and `socket` drivers add additional initializations to avoid valgrind warnings. * the `dpdk` driver is upgraded to dpdk 17.02 and is now also built with the `--whole-archive` option, which means that pmds no longer need to be linked individually but are automatically included in builds that make use of dpdk pktio support.

=== `odp-linux` time improvements * the odp time apis are now more efficiently handled by replacing the previous linux timespec with simple nanoseconds (ns) and using native hardware time counters in x86 and arm environments, when available.

=== `odp-linux` traffic manager improvements * weighting is now handled properly when weight=1 is specified. previously this caused an overflow that distorted packet priorities.

=== miscellaneous fixes and improvements ==== native clang build on armv8 armv8 compilation now works properly when using the clang compiler.

==== test improvements * the `odp_scheduling` performance test now handles dequeueing from potentially concurrent queues properly. * the traffic manager and time tests are now invoked via scripts to better account for load-sensitivity when running regressions in ci environments. * the l2fwd test now supports an additional parameter to specify the number of scheduling groups to use in the test. * the `odp_sched_latency` performance test now handles queue draining in a robust manner. * the crypto validation tests now properly check and validate message digests, and include negative tests to verify that incorrect digests are properly flagged. note that this may expose omissions in other odp implementations that had previously passed this validation test. * the crypto validation test now adds an explicit test for the null cipher, as well as hmac-sha-1 and hmac-sha-512. * the pktio_ipc test now properly cleans up only its own temp files.

==== examples improvements * the `odp_generator` example now properly honors stop criteria based on number of packets sent. * the `odp_generator` example now properly flushes output messages * the `odp_generator` example now supports port configuration.
