67
68   pldm_bios_table_iter_is_end() now returns true if the provided argument is
69   NULL.
70
712. Register assignment for parameters of a number of APIs changed with increased
72   scrutiny on their implementations.
73
74   - `decode_entity_auxiliary_names_pdr()`
75   - `decode_get_state_sensor_readings_resp()`
76   - `decode_oem_meta_file_io_req()`
77   - `decode_platform_event_message_req()`
78   - `decode_platform_event_message_resp()`
79   - `decode_sensor_op_data()`
80   - `encode_get_state_effecter_states_resp()`
81   - `encode_state_effecter_pdr()`
82   - `encode_state_sensor_pdr()`
83   - `pldm_bios_table_append_pad_checksum()`
84   - `pldm_bios_table_attr_value_entry_encode_enum()`
85   - `pldm_bios_table_attr_value_entry_encode_string()`
86   - `pldm_pdr_find_record()`
87   - `pldm_pdr_get_next_record()`
88
893. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req()
90
914. dsp: firmware_update: Bounds check
92   decode_downstream_device_parameter_table_entry_versions()
93
94   The additional bounds-checking required the addition of further length
95   parameters.
96
97### Deprecated
98
991. oem: meta: Deprecate `decode_oem_meta_file_io_req()`
100
101   Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this
102   function to make it safer.
103
104   Modification:
105
106   - The meaning of the returned result.
107   - Change parameters from individual pointers to a struct.
108   - Check the length provided in the message won't exceed the buffer.
109
1102. pldm_entity_association_tree_copy_root()
111
112   The implementation allocates, but gives no indication to the caller if an
113   allocation (and hence the copy) has failed. Users should migrate to
114   pldm_entity_association_tree_copy_root_check().
115
1163. The following APIs are deprecated as unsafe due to various unfixable CWE
117   violations:

170
171### Fixed
172
1731. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
174
175   Avoid a caller-controlled NULL pointer dereference in the library
176   implementation.
177
1782. platform: fix encode/decode_poll_for_platform_event_message_req
179
180   Update checking of `TransferOperationFlag` and `eventIDToAcknowledge` to
181   follow spec.
182
1833. platform: Fix checking `eventIDToAcknowledge`
184
185   As the event receiver sends `PollForPlatformEventMessage` with the
186   `tranferFlag` is `AcknowledgementOnly`, the value `eventIDToAcknowledge`
187   should be the previously retrieved eventID (from the PLDM terminus).
188
1894. dsp: platform: Prevent overflow of arithmetic on event_data_length
1905. dsp: platform: Bounds check encode_sensor_state_pdr()
1916. dsp: platform: Bounds check encode_state_effecter_pdr()
1927. dsp: pdr: Bounds check pldm_entity_association_pdr_extract()
1938. dsp: bios_table: Bounds check pldm_bios_table_append_pad_checksum()
1949. dsp: bios_table: Bounds check
195   pldm_bios_table_attr_value_entry_encode_string()
19610. dsp: bios_table: Bounds check pldm_bios_table_attr_value_entry_encode_enum()
19711. dsp: firmware_update: Bounds check
198    decode_downstream_device_parameter_table_entry_versions()

20215. dsp: bios: Bounds check encode_set_bios_table_req()
20316. dsp: bios: Bounds check encode_set_bios_attribute_current_value_req()
20417. dsp: bios_table: Bounds check pldm_bios_table_string_entry_encode()
20518. dsp: pdr: Rework test in pldm_entity_association_pdr_extract()

207
208## [0.9.1] - 2024-09-07
209
210### Changed
211
2121. Moved evolutions intended for v0.9.0 into place
213
214   Evolutions for the release have been moved from `evolutions/current` to
215   `evolutions/v0.9.1`. Library users can apply them to migrate off of
216   deprecated APIs.
217
218## [0.9.0] - 2024-09-07
219
220### Added
221
2221. base: Define macros for reserved TIDs
2232. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr()
2243. pdr: Add pldm_entity_association_pdr_create_new()
2254. platform: Define macros for the responded transferflags
2265. pdr: Add pldm_pdr_get_terminus_handle() API
2276. pdr: Add related decode_entity_auxiliary_names_pdr() APIs
2287. fw_update: Add encode req & decode resp for get_downstream_fw_params
2298. platform: Add decode_pldm_platform_cper_event() API
2309. decode_get_pdr_repository_info_resp_safe()
231
232   Replaces decode_get_pdr_repository_info_resp() as discussed in the
233   `Deprecated` section below
234
23510. decode_get_pdr_resp_safe()
236
237    Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section
238    below
239
240### Changed
241
2421. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs
2432. platform: Rework decode/encode_pldm_message_poll_event_data() APIs
2443. platform: Stabilise decode_pldm_message_poll_event_data() APIs
2454. ABI break for decode_sensor_op_data()
246
247   Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused
248   abi-compliance-checker to flag a change in the register containing the
249   parameter `previous_op_state`.
250
2515. platform: Stabilise decode_pldm_platform_cper_event() API
2526. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API
2537. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API
2548. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API
255
256### Deprecated
257
2581. Rename and deprecate functions with the `_check` suffix
259
260   All library function return values always need to be checked. The `_check`
261   suffix is redundant, so remove it. Migration to the non-deprecated
262   equivalents without the `_check` suffix can be performed using
263   `scripts/ apply-renames` and the [clang-rename][] configurations under
264   `evolutions/`
265
266   The deprecated functions:
267
268   - `get_fru_record_by_option_check()`
269   - `pldm_bios_table_append_pad_checksum_check()`
270   - `pldm_bios_table_attr_entry_enum_decode_def_num_check()`
271   - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()`
272   - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()`
273   - `pldm_bios_table_attr_entry_enum_encode_check()`
274   - `pldm_bios_table_attr_entry_integer_encode_check()`
275   - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()`
276   - `pldm_bios_table_attr_entry_string_encode_check()`
277   - `pldm_bios_table_attr_value_entry_encode_enum_check()`
278   - `pldm_bios_table_attr_value_entry_encode_integer_check()`
279   - `pldm_bios_table_attr_value_entry_encode_string_check()`
280   - `pldm_bios_table_string_entry_decode_string_check()`
281   - `pldm_bios_table_string_entry_encode_check()`
282   - `pldm_entity_association_pdr_add_check()`
283   - `pldm_entity_association_pdr_add_from_node_check()`
284   - `pldm_pdr_add_check()`
285   - `pldm_pdr_add_fru_record_set_check()`
286
287[clang-rename]: https://clang.llvm.org/extra/clang-rename.html
288
2892. `decode_get_pdr_repository_info_resp()`
290
291   Users should move to `decode_get_pdr_repository_info_resp_safe()` which
292   eliminates the opportunity for buffer overruns when extracting objects from
293   the message.
294
2953. `decode_get_pdr_resp()`
296
297   Users should move to `decode_get_pdr_resp_safe()` which reduces the
298   invocation tedium and improves memory safety over `decode_get_pdr_resp()`.
299
300### Removed
301
3021. IBM OEM header compatibility symlinks.
303
304   Anyone left using the deprecated paths can migrate using the coccinelle patch
305   at `evolutions/current/oem-ibm-header-compat.cocci`.
306
307### Fixed
308
3091. requester: instance-id: Release read lock on conflict
3102. pdr: Error propagation for
311   pldm_entity_association_pdr_add_from_node_with_record_handle()

463
464   The enum operational_fault_status is defined with wrong members and will
465   eventually be replaced with the correct members. Any uses of
466   pldm_state_set_operational_fault_status_values members should move to
467   equivalent pldm_state_set_operational_stress_status_values members if needed.

5178. pdr: Document preconditions for trivial accessor functions
518
519   A trivial accessor function is one that exposes properties of an object in a
520   way can't result in an error, beyond passing an invalid argument to the
521   function. For APIs meeting this definition we define a precondition that
522   struct pointers must point to valid objects to avoid polluting the function
523   prototypes. The following APIs now have this precondition explicitly defined:
524
525   - pldm_entity_extract()
526   - pldm_entity_get_parent()
527   - pldm_entity_is_exist_parent()
528   - pldm_entity_is_node_parent()
529   - pldm_is_current_parent_child

677   which ensure assertions won't fail or otherwise invoke UB:

680   - pldm_bios_table_string_entry_decode_string()
681   - pldm_bios_table_attr_entry_enum_encode()
