Register assignment for parameters of a number of APIs changed with increased 42 scrutiny on their implementations. 43 44 - `decode_entity_auxiliary_names_pdr()` 45 - `decode_get_state_sensor_readings_resp()` 46 - `decode_oem_meta_file_io_req()` 47 - `decode_platform_event_message_req()` 48 - `decode_platform_event_message_resp()` 49 - `decode_sensor_op_data()` 50 - `encode_get_state_effecter_states_resp()` 51 - `encode_state_effecter_pdr()` 52 - `encode_state_sensor_pdr()` 53 - `pldm_bios_table_append_pad_checksum()` 54 - `pldm_bios_table_attr_value_entry_encode_enum()` 55 - `pldm_bios_table_attr_value_entry_encode_string()` 56 - `pldm_pdr_find_record()` 57 - `pldm_pdr_get_next_record()` 58 593. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req() 60 614. dsp: firmware_update: Bounds check 62 decode_downstream_device_parameter_table_entry_versions() 63 64 The additional bounds-checking required the addition of further length 65 parameters. 66 67### Deprecated 68 691. oem: meta: Deprecate `decode_oem_meta_file_io_req()` 70 71 Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this 72 function to make it safer. 73 74 Modification: 75 76 - The meaning of the returned result. 77 - Change parameters from individual pointers to a struct. 78 - Check the length provided in the message won't exceed the buffer. 79 802. pldm_entity_association_tree_copy_root() 81 82 The implementation allocates, but gives no indication to the caller if an 83 allocation (and hence the copy) has failed. Users should migrate to 84 pldm_entity_association_tree_copy_root_check(). 85 863.

Moved evolutions intended for v0.9.0 into place 183 184 Evolutions for the release have been moved from `evolutions/current` to 185 `evolutions/v0.9.1`. Library users can apply them to migrate off of 186 deprecated APIs. 187 188## [0.9.0] - 2024-09-07 189 190### Added 191 1921. base: Define macros for reserved TIDs 1932. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr() 1943. pdr: Add pldm_entity_association_pdr_create_new() 1954. platform: Define macros for the responded transferflags 1965. pdr: Add pldm_pdr_get_terminus_handle() API 1976. pdr: Add related decode_entity_auxiliary_names_pdr() APIs 1987. fw_update: Add encode req & decode resp for get_downstream_fw_params 1998. platform: Add decode_pldm_platform_cper_event() API 2009. decode_get_pdr_repository_info_resp_safe() 201 202 Replaces decode_get_pdr_repository_info_resp() as discussed in the 203 `Deprecated` section below 204 20510. decode_get_pdr_resp_safe() 206 207 Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section 208 below 209 210### Changed 211 2121. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs 2132. platform: Rework decode/encode_pldm_message_poll_event_data() APIs 2143. platform: Stabilise decode_pldm_message_poll_event_data() APIs 2154.

Rename and deprecate functions with the `_check` suffix 229 230 All library function return values always need to be checked. The `_check` 231 suffix is redundant, so remove it. Migration to the non-deprecated 232 equivalents without the `_check` suffix can be performed using 233 `scripts/ apply-renames` and the [clang-rename][] configurations under 234 `evolutions/` 235 236 The deprecated functions: 237 238 - `get_fru_record_by_option_check()` 239 - `pldm_bios_table_append_pad_checksum_check()` 240 - `pldm_bios_table_attr_entry_enum_decode_def_num_check()` 241 - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()` 242 - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()` 243 - `pldm_bios_table_attr_entry_enum_encode_check()` 244 - `pldm_bios_table_attr_entry_integer_encode_check()` 245 - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()` 246 - `pldm_bios_table_attr_entry_string_encode_check()` 247 - `pldm_bios_table_attr_value_entry_encode_enum_check()` 248 - `pldm_bios_table_attr_value_entry_encode_integer_check()` 249 - `pldm_bios_table_attr_value_entry_encode_string_check()` 250 - `pldm_bios_table_string_entry_decode_string_check()` 251 - `pldm_bios_table_string_entry_encode_check()` 252 - `pldm_entity_association_pdr_add_check()` 253 - `pldm_entity_association_pdr_add_from_node_check()` 254 - `pldm_pdr_add_check()` 255 - `pldm_pdr_add_fru_record_set_check()` 256 257[clang-rename]: https://clang.llvm.org/extra/clang-rename.html 258 2592. `decode_get_pdr_repository_info_resp()` 260 261 Users should move to `decode_get_pdr_repository_info_resp_safe()` which 262 eliminates the opportunity for buffer overruns when extracting objects from 263 the message. 264 2653. `decode_get_pdr_resp()` 266 267 Users should move to `decode_get_pdr_resp_safe()` which reduces the 268 invocation tedium and improves memory safety over `decode_get_pdr_resp()`. 269 270### Removed 271 2721.
