It completes the new +APIs that are part of the Tiger Moth Long Term Support (LTS) release of ODP +as well as various performance refinements and bug fixes. As of RC2 the ODP +API is now frozen for the Tiger Moth development series. + +==== APIs +The following new and changed APIs are included in this release: + +===== Addition of Shared Memory (SHM) Initialization Parameters +The `odp_init_t` struct used as the argument to the `odp_init_global()` API +has been expanded to include a `max_memory` field that specifies the maximum +amount of shared memory (shm) that the application will use. This is to +better enable ODP implementations to optimize their use of shared memory in +support of the application. If left as (or defaulted) to 0, the implementation +may choose a default limit for the application. + +===== Crypto Changes +A number of crypto refinements are included in this release: + +* The single initialization vector (`iv`) in the `odp_crypto_session_param_t` +is replaced by a separate `cipher_iv` and `auth_iv` fields. + +* The single initialization vector (`override_iv_ptr`) in the +`odp_crypto_op_param_t` is replaced by a separate `cipher_iv_ptr` and +`auth_iv_ptr` fields. + +* The special nature of GCM and GMAC authenticated encryption modes is +clarified in that these ciphers always combine ciphering with authentication +and hence require both to be specified when used. This is simply a +documentation change as this requirement has always existed. + +* Enumerations for AES_CCM (`ODP_CIPHER_ALG_AES_CCM` and +`ODP_AUTH_ALG_AES_CCM`) authenticated encryption modes are added. + +* Enumeration for the AES_CMAC authenticated encryption mode +(`ODP_AUTH_ALG_AES_CMAC`) is added. + +* Enumerations for the ChaCha20-Poly1305 (`ODP_CIPHER_ALG_CHACHA20_POLY1305` +and `ODP_AUTH_ALG_CHACHA20_POLY1305`) authenticated encryption modes are +added. + +* Enumeration for the SHA-384 authentication algorithm +(`ODP_AUTH_ALG_SHA384_HMAC`) is added. + +* Enumeration for the AES-XCBC-MAC authentication algorithm +(`ODP_AUTH_ALG_AES_XCBC_MAC`) is added. + +===== Lock-free and block-free queues +The `odp_nonblocking_t` enums introduced in ODP v1.17.0.0 are now returned +as separate `odp_queue_capability()` limits for plain and scheduled queues. The +ODP reference implementations now support `ODP_NONBLOCKING_LF` queues. + +===== User pointer initialized to NULL +The specification for `odp_packet_user_ptr()` is clarified that unless +overridden by `odp_packet_user_ptr_set()` the value of NULL will be returned. + +===== Removal of `ODP_PKTIN_WAIT` option +The `ODP_PKTIN_WAIT` option on `odp_pktin_recv_tmo()` and +`odp_pktin_recv_mq_tmo()` is removed. Timeout options now consist of +`ODP_PKTIN_NO_WAIT` and a user-supplied timeout value. Since this timeout +value can be specified to be arbitrarily long, there is no need for an +indefinite wait capability as provision of such a capability proved +problematic for some ODP implementations. + +===== Addition of packet protocol APIs +The APIs `odp_packet_l2_type()`, `odp_packet_l3_type()`, and +`odp_packet_l4_type()` are added to return the Layer 2, 3, and 4 protocols, +respectively, associated with packets that have been parsed to the +corresponding layer. If the packet was not parsed to the associated layer +these return `ODP_PROTO_Ln_TYPE_NONE`. + +===== Packet addressability improvements +The documentation of `odp_packet_data()` is clarified to indicated when this +shortcut may be used safely and a new API, `odp_packet_data_seg_len()`, is +added that returns both the address of the start of packet data as well +as the number of bytes addressable from that pointer. + +===== Asynchronous ordered locks +Two new APIs, `odp_schedule_order_lock_start()` and +`odp_schedule_order_lock_wait()` are added to allow for asynchronous +ordered lock acquisition in addition to the existing synchronous +`odp_schedule_order_lock()` API. In some implementations and applications, +there may be a performance advantage to indicating the intent to acquire an +ordered lock to allow the implementation to prepare for this while the +application continues parallel processing and then enter the critical section +protected by the ordered lock at a later time. In this case ordered lock +protection is not guaranteed until the `odp_schedule_order_lock_wait()` call +returns. + +===== IPsec API miscellaneous changes and enhancements +IPsec support is further enhanced with the following: + +* The `odp_ipsec_ipv4_param_t` and `odp_ipsec_ipv6_param_t` structures +are added to formalize the specification of IPv4 and IPv6 options in the +`odp_ipsec_tunnel_param_t` configuration. + +* The `mode` field of the `odp_ipsec_out_t` is renamed to `frag_mode` for +better clarity. In addition the `flag.frag-mode` option bit in the +`odp_ipsec_out_opt_t` struct is defined to hold per-operation options for +the `odp_ipsec_out_param_t` struct. + +* The `odp_ipsec_capability_t` struct returned by the `odp_ipsec_capability()` +API is expanded to include the `odp_proto_chksums_t` available on inbound +IPsec traffic. This indicates whether and how inbound packet checksums may +be validated for decrypted IPsec traffic. + +===== IPsec Traffic Flow Confidentiality (TFC) support +Traffic Flow Confidentiality (TFC) allows applications to defend against +traffic analysis attacks by inserting dummy packets as well as add pad bytes +to packets traversing IPsec flows. + +Dummy packets have an L3 type of `ODP_PROTO_L3_TYPE_NONE` in tunnel mode and +`ODP_PROTO_L4_TYPE_NO_NEXT` in transport mode. Padded packets have additional +data suffixed to them that extends beyond the L3 or L4 packet lengths. + +For RX processing, inline dummy packets may or may not be dropped from the +inbound packet stream. For lookaside processing they are always visible. For TX +processing, the `odp_ipsec_out_opt_t` struct specifies the `tfc_pad` bit if +the packet is to be padded or the `tfc_dummy` bit if a dummy packet is to +be inserted. The dummy packet length is specified by the `tfc_pad_len` option. + +=== Streamlined ABI Support +ABI support has been reorganized to make it more modular and to omit headers +and related ABI files when configure to disable this support. + +=== Reference Implementation Fixes and Improvements +The ODP Reference Implementation corporates a number of improvements that +result in better code organization as well as improved processing efficiency. + +==== Pktio null device support +In the LNG Reference Implemenations of ODP, the `odp_pktio_open()` API may now +specify devices of class `null` to indicate the PktIO is treated as a dummy +device. Null devices behave just like Linux `/dev/null` in that they never +receive packets and simply discard any packets sent to them. + +Note that not all ODP implementations may support this device class. The +specific device classes supported by each ODP implementation may vary and are +listed in their own documentation. + +==== Runtime Scheduler Selection +The ODP Reference Implementation offers both a default and a number of +alternate scheduler implementations. Previously these were selectable only at +`configure` time. They can now be dynamically selected at runtime by the use +of the `ODP_SCHEDULER` environment variable. If this environment variable is +not set, the default (basic) scheduler is used. It can be set to select +alternate schedulers: + +* `ODP_SCHEDULER=basic` Explicitly selects the default scheduler +* `ODP_SCHEDULER=sp` Selects the strict priority scheduler +* `ODP_SCHEDULER=iquery` Selects the iQuery scheduler +* `ODP_SCHEDULER=scalable` Selects the scalable scheduler + +==== Streamlined Queue Implementation +The ODP Reference Implementation now uses a ring model for implementing +ODP queues. This results in greatly improved efficiency for queue operations. +The default maximum queue depth used is 4096 elements, and this information is +returned via the `odp_queue_capability()` API. + +==== Validation Test Simplification +The tests that are part of the validation test suite are reorganized and +simplified by having a single test file for each API rather than separate +CUnit driver files and test files. + +=== Test/Example Improvements + +==== Crypto Test Improvements +The `crypto` validation test suite now offers better information on which +crypto algorithms were skipped because they are not available. Testing of +full HMAC lengths is now added + +==== ODP Generator Improvements +The `odp_generator` example now offers configurable RX burst size, selectable +packet handling (Direct I/O or Scheduled I/O), as well as streamlined packet +processing. + +==== `l2fwd` Example Improvements +The `l2fwd` example offers improved efficiency via better cache usage. + +=== Bug Fixes + +==== https://bugs.linaro.org/show_bug.cgi?id=3517%5BBug 3517] +timer test might fail + +==== https://bugs.linaro.org/show_bug.cgi?id=3572%5BBug 3572] +time_main test fails if run under heavy load + +==== https://bugs.linaro.org/show_bug.cgi?id=3576%5BBug 3576] +classification: CoS queues in invalid table index + +==== https://bugs.linaro.org/show_bug.cgi?id=3577%5BBug 3577] +classification: multiqueue CoS will always fail + +==== https://bugs.linaro.org/show_bug.cgi?id=3578%5BBug 3578] +classification: requested number of queues is ignored in multiqueue CoS + +==== https://bugs.linaro.org/show_bug.cgi?id=3579%5BBug 3579] +cls: capability to return max hash queues + +==== https://bugs.linaro.org/show_bug.cgi?id=3581%5BBug 3581] +classification: invalid memory access in RSS hash + +==== https://bugs.linaro.org/show_bug.cgi?id=3582%5BBug 3582] +classification: incorrect IPv6 RSS hash + +==== https://bugs.linaro.org/show_bug.cgi?id=3594%5BBug 3594] +IPsec SA may be used before fully initialized + +==== https://bugs.linaro.org/show_bug.cgi?id=3595%5BBug 3595] +IPsec SA lookup may leave extra SAs locked + +==== https://bugs.linaro.org/show_bug.cgi?id=3597%5BBug 3597] +new generator test assumes that null:0 pktio is always present + +==== https://bugs.linaro.org/show_bug.cgi?id=3613%5BBug 3613] +packet_main test can fail + +==== 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=3618%5BBug 3618] +DPDK pktio stops receiving packets if all configured RX queues are not used + +==== https://bugs.linaro.org/show_bug.cgi?id=3628%5BBug 3628] +Another timer_main failure + +==== https://bugs.linaro.org/show_bug.cgi?id=3632%5BBug 3632] +Creating a pool with total size over 4.29GB (UINT32_MAX) leads to +undefined behavior + +=== Known Issues + +==== https://bugs.linaro.org/show_bug.cgi?id=2988%5BBug 2988] +ODP exposes symbols outside of odp*/_odp* namespace + == OpenDataPlane (1.17.0.0) === New Features ODP v1.17.0.0 is Tiger Moth Release Candidate 1 (RC 1).
