33
34### Changed
35
361. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
37
38   pldm_bios_table_iter_is_end() now returns true if the provided argument is
39   NULL.
40
412. 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. The following APIs are deprecated as unsafe due to various unfixable CWE
87   violations:
88

140
141### Fixed
142
1431. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
144
145   Avoid a caller-controlled NULL pointer dereference in the library
146   implementation.
147
1482. platform: fix encode/decode_poll_for_platform_event_message_req
149
150   Update checking of `TransferOperationFlag` and `eventIDToAcknowledge` to
151   follow spec.
152
1533. platform: Fix checking `eventIDToAcknowledge`
154
155   As the event receiver sends `PollForPlatformEventMessage` with the
156   `tranferFlag` is `AcknowledgementOnly`, the value `eventIDToAcknowledge`
157   should be the previously retrieved eventID (from the PLDM terminus).
158
1594. dsp: platform: Prevent overflow of arithmetic on event_data_length
1605. dsp: platform: Bounds check encode_sensor_state_pdr()
1616. dsp: platform: Bounds check encode_state_effecter_pdr()
1627. dsp: pdr: Bounds check pldm_entity_association_pdr_extract()
1638. dsp: bios_table: Bounds check pldm_bios_table_append_pad_checksum()
1649. dsp: bios_table: Bounds check

17114. dsp: fru: Bounds check encode_fru_record()
17215. dsp: bios: Bounds check encode_set_bios_table_req()
17316. dsp: bios: Bounds check encode_set_bios_attribute_current_value_req()
17417. dsp: bios_table: Bounds check pldm_bios_table_string_entry_encode()

176
177## [0.9.1] - 2024-09-07
178
179### Changed
180
1811. Moved evolutions intended for v0.9.0 into place
182
183   Evolutions for the release have been moved from `evolutions/current` to
184   `evolutions/v0.9.1`. Library users can apply them to migrate off of
185   deprecated APIs.
186
187## [0.9.0] - 2024-09-07
188
189### Added
190
1911. base: Define macros for reserved TIDs
1922. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr()
1933. pdr: Add pldm_entity_association_pdr_create_new()
1944. platform: Define macros for the responded transferflags
1955. pdr: Add pldm_pdr_get_terminus_handle() API
1966. pdr: Add related decode_entity_auxiliary_names_pdr() APIs
1977. fw_update: Add encode req & decode resp for get_downstream_fw_params
1988. platform: Add decode_pldm_platform_cper_event() API
1999. decode_get_pdr_repository_info_resp_safe()
200
201   Replaces decode_get_pdr_repository_info_resp() as discussed in the
202   `Deprecated` section below
203
20410. decode_get_pdr_resp_safe()
205
206    Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section
207    below
208
209### Changed
210
2111. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs
2122. platform: Rework decode/encode_pldm_message_poll_event_data() APIs
2133. platform: Stabilise decode_pldm_message_poll_event_data() APIs
2144. ABI break for decode_sensor_op_data()
215
216   Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused
217   abi-compliance-checker to flag a change in the register containing the
218   parameter `previous_op_state`.
219
2205. platform: Stabilise decode_pldm_platform_cper_event() API
2216. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API
2227. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API
2238. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API
224
225### Deprecated
226
2271. Rename and deprecate functions with the `_check` suffix
228
229   All library function return values always need to be checked. The `_check`
230   suffix is redundant, so remove it. Migration to the non-deprecated
231   equivalents without the `_check` suffix can be performed using
232   `scripts/ apply-renames` and the [clang-rename][] configurations under
233   `evolutions/`
234
235   The deprecated functions:
236
237   - `get_fru_record_by_option_check()`
238   - `pldm_bios_table_append_pad_checksum_check()`
239   - `pldm_bios_table_attr_entry_enum_decode_def_num_check()`
240   - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()`
241   - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()`
242   - `pldm_bios_table_attr_entry_enum_encode_check()`
243   - `pldm_bios_table_attr_entry_integer_encode_check()`
244   - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()`
245   - `pldm_bios_table_attr_entry_string_encode_check()`
246   - `pldm_bios_table_attr_value_entry_encode_enum_check()`
247   - `pldm_bios_table_attr_value_entry_encode_integer_check()`
248   - `pldm_bios_table_attr_value_entry_encode_string_check()`
249   - `pldm_bios_table_string_entry_decode_string_check()`
250   - `pldm_bios_table_string_entry_encode_check()`
251   - `pldm_entity_association_pdr_add_check()`
252   - `pldm_entity_association_pdr_add_from_node_check()`
253   - `pldm_pdr_add_check()`
254   - `pldm_pdr_add_fru_record_set_check()`
255
256[clang-rename]: https://clang.llvm.org/extra/clang-rename.html
257
2582. `decode_get_pdr_repository_info_resp()`
259
260   Users should move to `decode_get_pdr_repository_info_resp_safe()` which
261   eliminates the opportunity for buffer overruns when extracting objects from
262   the message.
263
2643. `decode_get_pdr_resp()`
265
266   Users should move to `decode_get_pdr_resp_safe()` which reduces the
267   invocation tedium and improves memory safety over `decode_get_pdr_resp()`.
268
269### Removed
270
2711. IBM OEM header compatibility symlinks.
272
273   Anyone left using the deprecated paths can migrate using the coccinelle patch
274   at `evolutions/current/oem-ibm-header-compat.cocci`.
275
276### Fixed
277
2781. requester: instance-id: Release read lock on conflict
2792. pdr: Error propagation for
280   pldm_entity_association_pdr_add_from_node_with_record_handle()

432
433   The enum operational_fault_status is defined with wrong members and will
434   eventually be replaced with the correct members. Any uses of
435   pldm_state_set_operational_fault_status_values members should move to
436   equivalent pldm_state_set_operational_stress_status_values members if needed.

4868. pdr: Document preconditions for trivial accessor functions
487
488   A trivial accessor function is one that exposes properties of an object in a
489   way can't result in an error, beyond passing an invalid argument to the
490   function. For APIs meeting this definition we define a precondition that
491   struct pointers must point to valid objects to avoid polluting the function
492   prototypes. The following APIs now have this precondition explicitly defined:
493
494   - pldm_entity_extract()
495   - pldm_entity_get_parent()
496   - pldm_entity_is_exist_parent()
497   - pldm_entity_is_node_parent()
498   - pldm_is_current_parent_child
499   - pldm_is_empty_entity_assoc_tree()
500   - pldm_pdr_get_record_count()

649   - pldm_bios_table_string_entry_decode_string()
650   - pldm_bios_table_attr_entry_enum_encode()
