35
36### Changed
37
381. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
39
40   pldm_bios_table_iter_is_end() now returns true if the provided argument is
41   NULL.
42
432. Register assignment for parameters of a number of APIs changed with increased
44   scrutiny on their implementations.
45
46   - `decode_entity_auxiliary_names_pdr()`
47   - `decode_get_state_sensor_readings_resp()`
48   - `decode_oem_meta_file_io_req()`
49   - `decode_platform_event_message_req()`
50   - `decode_platform_event_message_resp()`
51   - `decode_sensor_op_data()`
52   - `encode_get_state_effecter_states_resp()`
53   - `encode_state_effecter_pdr()`
54   - `encode_state_sensor_pdr()`
55   - `pldm_bios_table_append_pad_checksum()`
56   - `pldm_bios_table_attr_value_entry_encode_enum()`
57   - `pldm_bios_table_attr_value_entry_encode_string()`
58   - `pldm_pdr_find_record()`
59   - `pldm_pdr_get_next_record()`
60
613. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req()
62
634. dsp: firmware_update: Bounds check
64   decode_downstream_device_parameter_table_entry_versions()
65
66   The additional bounds-checking required the addition of further length
67   parameters.
68
69### Deprecated
70
711. oem: meta: Deprecate `decode_oem_meta_file_io_req()`
72
73   Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this
74   function to make it safer.
75
76   Modification:
77
78   - The meaning of the returned result.
79   - Change parameters from individual pointers to a struct.
80   - Check the length provided in the message won't exceed the buffer.
81
822. pldm_entity_association_tree_copy_root()
83
84   The implementation allocates, but gives no indication to the caller if an
85   allocation (and hence the copy) has failed. Users should migrate to
86   pldm_entity_association_tree_copy_root_check().
87
883. The following APIs are deprecated as unsafe due to various unfixable CWE
89   violations:

142
143### Fixed
144
1451. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
146
147   Avoid a caller-controlled NULL pointer dereference in the library
148   implementation.
149
1502. platform: fix encode/decode_poll_for_platform_event_message_req
151
152   Update checking of `TransferOperationFlag` and `eventIDToAcknowledge` to
153   follow spec.
154
1553. platform: Fix checking `eventIDToAcknowledge`
156
157   As the event receiver sends `PollForPlatformEventMessage` with the
158   `tranferFlag` is `AcknowledgementOnly`, the value `eventIDToAcknowledge`
159   should be the previously retrieved eventID (from the PLDM terminus).
160
1614. dsp: platform: Prevent overflow of arithmetic on event_data_length
1625. dsp: platform: Bounds check encode_sensor_state_pdr()
1636. dsp: platform: Bounds check encode_state_effecter_pdr()

179
180## [0.9.1] - 2024-09-07
181
182### Changed
183
1841. Moved evolutions intended for v0.9.0 into place
185
186   Evolutions for the release have been moved from `evolutions/current` to
187   `evolutions/v0.9.1`. Library users can apply them to migrate off of
188   deprecated APIs.
189
190## [0.9.0] - 2024-09-07
191
192### Added
193
1941. base: Define macros for reserved TIDs
1952. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr()
1963. pdr: Add pldm_entity_association_pdr_create_new()
1974. platform: Define macros for the responded transferflags
1985. pdr: Add pldm_pdr_get_terminus_handle() API
1996. pdr: Add related decode_entity_auxiliary_names_pdr() APIs
2007. fw_update: Add encode req & decode resp for get_downstream_fw_params
2018. platform: Add decode_pldm_platform_cper_event() API
2029. decode_get_pdr_repository_info_resp_safe()
203
204   Replaces decode_get_pdr_repository_info_resp() as discussed in the
205   `Deprecated` section below
206
20710. decode_get_pdr_resp_safe()
208
209    Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section
210    below
211
212### Changed
213
2141. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs
2152. platform: Rework decode/encode_pldm_message_poll_event_data() APIs
2163. platform: Stabilise decode_pldm_message_poll_event_data() APIs
2174. ABI break for decode_sensor_op_data()
218
219   Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused
220   abi-compliance-checker to flag a change in the register containing the
221   parameter `previous_op_state`.
222
2235. platform: Stabilise decode_pldm_platform_cper_event() API
2246. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API
2257. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API
2268. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API
227
228### Deprecated
229
2301. Rename and deprecate functions with the `_check` suffix
231
232   All library function return values always need to be checked. The `_check`
233   suffix is redundant, so remove it. Migration to the non-deprecated
234   equivalents without the `_check` suffix can be performed using
235   `scripts/ apply-renames` and the [clang-rename][] configurations under
236   `evolutions/`
237
238   The deprecated functions:
239
240   - `get_fru_record_by_option_check()`
241   - `pldm_bios_table_append_pad_checksum_check()`
242   - `pldm_bios_table_attr_entry_enum_decode_def_num_check()`
243   - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()`
244   - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()`
245   - `pldm_bios_table_attr_entry_enum_encode_check()`
246   - `pldm_bios_table_attr_entry_integer_encode_check()`
247   - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()`
248   - `pldm_bios_table_attr_entry_string_encode_check()`
249   - `pldm_bios_table_attr_value_entry_encode_enum_check()`
250   - `pldm_bios_table_attr_value_entry_encode_integer_check()`
251   - `pldm_bios_table_attr_value_entry_encode_string_check()`
252   - `pldm_bios_table_string_entry_decode_string_check()`
253   - `pldm_bios_table_string_entry_encode_check()`
254   - `pldm_entity_association_pdr_add_check()`
255   - `pldm_entity_association_pdr_add_from_node_check()`
256   - `pldm_pdr_add_check()`
257   - `pldm_pdr_add_fru_record_set_check()`
258
259[clang-rename]: https://clang.llvm.org/extra/clang-rename.html
260
2612. `decode_get_pdr_repository_info_resp()`
262
263   Users should move to `decode_get_pdr_repository_info_resp_safe()` which
264   eliminates the opportunity for buffer overruns when extracting objects from
265   the message.
266
2673. `decode_get_pdr_resp()`
268
269   Users should move to `decode_get_pdr_resp_safe()` which reduces the
270   invocation tedium and improves memory safety over `decode_get_pdr_resp()`.
271
272### Removed
273
2741. IBM OEM header compatibility symlinks.
275
276   Anyone left using the deprecated paths can migrate using the coccinelle patch
277   at `evolutions/current/oem-ibm-header-compat.cocci`.
278
279### Fixed
280
2811. requester: instance-id: Release read lock on conflict
2822. pdr: Error propagation for
283   pldm_entity_association_pdr_add_from_node_with_record_handle()

435
436   The enum operational_fault_status is defined with wrong members and will
437   eventually be replaced with the correct members. Any uses of
438   pldm_state_set_operational_fault_status_values members should move to

4898. pdr: Document preconditions for trivial accessor functions
490
491   A trivial accessor function is one that exposes properties of an object in a
492   way can't result in an error, beyond passing an invalid argument to the
493   function. For APIs meeting this definition we define a precondition that
494   struct pointers must point to valid objects to avoid polluting the function
495   prototypes. The following APIs now have this precondition explicitly defined:
496
497   - pldm_entity_extract()
498   - pldm_entity_get_parent()
499   - pldm_entity_is_exist_parent()
500   - pldm_entity_is_node_parent()
501   - pldm_is_current_parent_child
502   - pldm_is_empty_entity_assoc_tree()
503   - pldm_pdr_get_record_count()
504   - pldm_pdr_get_record_handle()

652   - pldm_bios_table_string_entry_decode_string()
653   - pldm_bios_table_attr_entry_enum_encode()
