68
691. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
70
71   pldm_bios_table_iter_is_end() now returns true if the provided argument is
72   NULL.
73
742. Register assignment for parameters of a number of APIs changed with increased
75   scrutiny on their implementations.
76
77   - `decode_entity_auxiliary_names_pdr()`
78   - `decode_get_state_sensor_readings_resp()`
79   - `decode_oem_meta_file_io_req()`
80   - `decode_platform_event_message_req()`
81   - `decode_platform_event_message_resp()`
82   - `decode_sensor_op_data()`
83   - `encode_get_state_effecter_states_resp()`
84   - `encode_state_effecter_pdr()`
85   - `encode_state_sensor_pdr()`
86   - `pldm_bios_table_append_pad_checksum()`
87   - `pldm_bios_table_attr_value_entry_encode_enum()`
88   - `pldm_bios_table_attr_value_entry_encode_string()`
89   - `pldm_pdr_find_record()`
90   - `pldm_pdr_get_next_record()`
91
923. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req()
93
944. dsp: firmware_update: Bounds check
95   decode_downstream_device_parameter_table_entry_versions()
96
97   The additional bounds-checking required the addition of further length
98   parameters.
99
100### Deprecated
101
1021. oem: meta: Deprecate `decode_oem_meta_file_io_req()`
103
104   Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this
105   function to make it safer.
106
107   Modification:
108
109   - The meaning of the returned result.
110   - Change parameters from individual pointers to a struct.
111   - Check the length provided in the message won't exceed the buffer.
112
1132. pldm_entity_association_tree_copy_root()
114
115   The implementation allocates, but gives no indication to the caller if an
116   allocation (and hence the copy) has failed. Users should migrate to
117   pldm_entity_association_tree_copy_root_check().
118
1193. The following APIs are deprecated as unsafe due to various unfixable CWE
120   violations:
121

173
174### Fixed
175
1761. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()
177
178   Avoid a caller-controlled NULL pointer dereference in the library
179   implementation.
180
1812. platform: fix encode/decode_poll_for_platform_event_message_req
182
183   Update checking of `TransferOperationFlag` and `eventIDToAcknowledge` to
184   follow spec.
185
1863. platform: Fix checking `eventIDToAcknowledge`
187
188   As the event receiver sends `PollForPlatformEventMessage` with the
189   `tranferFlag` is `AcknowledgementOnly`, the value `eventIDToAcknowledge`
190   should be the previously retrieved eventID (from the PLDM terminus).
191
1924. dsp: platform: Prevent overflow of arithmetic on event_data_length
1935. dsp: platform: Bounds check encode_sensor_state_pdr()
1946. dsp: platform: Bounds check encode_state_effecter_pdr()
1957. dsp: pdr: Bounds check pldm_entity_association_pdr_extract()
1968. dsp: bios_table: Bounds check pldm_bios_table_append_pad_checksum()

198   pldm_bios_table_attr_value_entry_encode_string()
19910. dsp: bios_table: Bounds check pldm_bios_table_attr_value_entry_encode_enum()
20011. dsp: firmware_update: Bounds check

210
211## [0.9.1] - 2024-09-07
212
213### Changed
214
2151. Moved evolutions intended for v0.9.0 into place
216
217   Evolutions for the release have been moved from `evolutions/current` to
218   `evolutions/v0.9.1`. Library users can apply them to migrate off of
219   deprecated APIs.
220
221## [0.9.0] - 2024-09-07
222
223### Added
224
2251. base: Define macros for reserved TIDs
2262. pdr: Add pldm_entity_association_pdr_add_contained_entity_to_remote_pdr()
2273. pdr: Add pldm_entity_association_pdr_create_new()
2284. platform: Define macros for the responded transferflags
2295. pdr: Add pldm_pdr_get_terminus_handle() API
2306. pdr: Add related decode_entity_auxiliary_names_pdr() APIs
2317. fw_update: Add encode req & decode resp for get_downstream_fw_params
2328. platform: Add decode_pldm_platform_cper_event() API
2339. decode_get_pdr_repository_info_resp_safe()
234
235   Replaces decode_get_pdr_repository_info_resp() as discussed in the
236   `Deprecated` section below
237
23810. decode_get_pdr_resp_safe()
239
240    Replaces decode_get_pdr_resp() as discussed in the `Deprecated` section
241    below
242
243### Changed
244
2451. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs
2462. platform: Rework decode/encode_pldm_message_poll_event_data() APIs
2473. platform: Stabilise decode_pldm_message_poll_event_data() APIs
2484. ABI break for decode_sensor_op_data()
249
250   Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused
251   abi-compliance-checker to flag a change in the register containing the
252   parameter `previous_op_state`.
253
2545. platform: Stabilise decode_pldm_platform_cper_event() API
2556. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API
2567. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API
2578. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API
258
259### Deprecated
260
2611. Rename and deprecate functions with the `_check` suffix
262
263   All library function return values always need to be checked. The `_check`
264   suffix is redundant, so remove it. Migration to the non-deprecated
265   equivalents without the `_check` suffix can be performed using
266   `scripts/ apply-renames` and the [clang-rename][] configurations under
267   `evolutions/`
268
269   The deprecated functions:
270
271   - `get_fru_record_by_option_check()`
272   - `pldm_bios_table_append_pad_checksum_check()`
273   - `pldm_bios_table_attr_entry_enum_decode_def_num_check()`
274   - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()`
275   - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()`
276   - `pldm_bios_table_attr_entry_enum_encode_check()`
277   - `pldm_bios_table_attr_entry_integer_encode_check()`
278   - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()`
279   - `pldm_bios_table_attr_entry_string_encode_check()`
280   - `pldm_bios_table_attr_value_entry_encode_enum_check()`
281   - `pldm_bios_table_attr_value_entry_encode_integer_check()`
282   - `pldm_bios_table_attr_value_entry_encode_string_check()`
283   - `pldm_bios_table_string_entry_decode_string_check()`
284   - `pldm_bios_table_string_entry_encode_check()`
285   - `pldm_entity_association_pdr_add_check()`
286   - `pldm_entity_association_pdr_add_from_node_check()`
287   - `pldm_pdr_add_check()`
288   - `pldm_pdr_add_fru_record_set_check()`
289
290[clang-rename]: https://clang.llvm.org/extra/clang-rename.html
291
2922. `decode_get_pdr_repository_info_resp()`
293
294   Users should move to `decode_get_pdr_repository_info_resp_safe()` which
295   eliminates the opportunity for buffer overruns when extracting objects from
296   the message.
297
2983. `decode_get_pdr_resp()`
299
300   Users should move to `decode_get_pdr_resp_safe()` which reduces the
301   invocation tedium and improves memory safety over `decode_get_pdr_resp()`.
302
303### Removed
304
3051. IBM OEM header compatibility symlinks.
306
307   Anyone left using the deprecated paths can migrate using the coccinelle patch
308   at `evolutions/current/oem-ibm-header-compat.cocci`.
309
310### Fixed
311
3121. requester: instance-id: Release read lock on conflict
3132. pdr: Error propagation for
314   pldm_entity_association_pdr_add_from_node_with_record_handle()

4101. All the existing "requester" APIs from `libpldm/pldm.h` (also known as

5208. pdr: Document preconditions for trivial accessor functions
521
522   A trivial accessor function is one that exposes properties of an object in a
523   way can't result in an error, beyond passing an invalid argument to the
524   function. For APIs meeting this definition we define a precondition that
525   struct pointers must point to valid objects to avoid polluting the function
526   prototypes. The following APIs now have this precondition explicitly defined:
527
528   - pldm_entity_extract()
529   - pldm_entity_get_parent()
530   - pldm_entity_is_exist_parent()
531   - pldm_entity_is_node_parent()
