Release 1.9.3 of bmv2

Notable bug fixes since 1.9.2:

• call export_bytes in Data::two_comp_mod operator

Release 1.9.2 of bmv2

Notable bug fixes since 1.9.1:

• copy internal PHV state for header stacks when creating packet copies
• add missing includes
• do not crash in CLI if match field format is bad
• do not use Werror by default when building, can be enabled when running configure with --enable-Werror

Release 1.9.1 of bmv2

Notable bug fixes since 1.9.0:

• fix pcap file corruption when using --pcap-dump
• fix compilation warnings with gcc7

Release 1.9.0 of bmv2

• ability to init the Switch with an OptionsParser object (instead of argv)
• implemented _pi_update_device functions for bmv2
• ability to send / receive dataplane packets in simple_switch_grpc with a gRPC service (new DevMgrIface implementation)
• move simple_switch_grpc unit tests to GoogleTest
• enable JSON swap by default for simple_switch_grpc
• ability to pass "extras" KV map when adding port; this is useful for custom DevMgrIface implementations
• add bm_register_read_all to Thrift interface
• register logger with P4Runtime library in simple_switch_grpc
• dissociate checksum verification and update in JSON (some checksums can be verify-only, others update-only)
• support 64-bit device ids; this required updating the nanomsg notification headers

Release 1.8.1 of bmv2

Notable bug fixes since 1.8.0:

• don't crash in runtime APIs if invalid resource name
• give error for duplicate ports or LAGs in simple_switch_CLI

Release 1.8.0 of bmv2

• ability to chose gRPC server address for simple_switch_grpc
• extra logging (with source info) when evaluating conditions and calling action primitives
• support for calling actions directly from control
• now using gcc6 in regressions instead of gcc5 (in addition to gcc4.8); we want to support gcc4.8 -> gcc6; we no longer run regressions with clang3.6 but we still do with clang3.8
• thrift RPC to clear all entries in a table: bm_mt_clear_entries
• verify checksums at the end of parsing and log an error message if checksum is not correct
• add ability to print supported bmv2 JSON version with --json-version command line option
• check that JSON version is supported in P4Objects when loading the JSON input
• gRPC requirement to use simple_switch_grpc is now 1.3.0
• removed the OverwritingHeader parser error, which is no longer part of the P4_16 spec
• add support for conditional jumps in actions, which enables us to support conditions in action bodies (P4_16) directly
• more advanced support for CRCs, with a list of predefined algos and the ability to specify your own polynomials in the JSON input
• support for P4_14 saturating fields
• thrift RPC to query the (JSON) id of an object by name: bm_get_id_from_name
• stub implementation of gNMI handler in simple_switch_grpc
• packet IO support in simple_switch_grpc

Release 1.7.2 of bmv2

Bug fixes since 1.7.1:

• fix major bug in ternary table implementations (lookup results were wrong after deleting an entry because of invalid handle computation)
• fix typo in P4Objects code which sets arith for union fields
• remove statements with side-effects from asserts, in case code is compiled with NDEBUG
• fix ByteContainer::to_hex to not use operator [] to get an "iterator" to the end of the vector; in debug mode, clang perform bound checking even for operator []

Release 1.7.1 of bmv2

Bug fixes since 1.7.0:

• fix issue with VL fields handling in JSON parser
• more robust JSON parsing: replaced asserts with error messages, header & field name validation
• setting arith property for checksum target fields when parsing JSON
• fix g++6 compilation warning
• fix crash in PRE

Release 1.7.0 of bmv2

• more comprehensive header stack support in expression engine
• tentative support for method calls in parse state body
• support for static table initializers
• support for shift in parser
• exact match cache for ternary / range tables to avoid linear search
• tentative implementation of the PI C API (bypassing Thrift RPC server)
• conditional dependency on Thrift and nanomsg, controlled by configure script
• new simple_switch_grpc target, which does not use Thrift for dataplane configuration
• tentative support for P4_16 header unions

Release 1.6.1 of bmv2

minor bug fixes since 1.6.0
