ABI break for pldm_pdr_get_next_record() 47 48 Register assignment for function parameters was changed with the removal of 49 some asserts in related implementations. 50 51### Deprecated 52 531. oem: meta: Deprecate `decode_oem_meta_file_io_req()` 54 55 Users should switch to `decode_oem_meta_file_io_write_req()`. Modify this 56 function to make it safer. 57 58 Modification: 59 60 - The meaning of the returned result. 61 - Change parameters from individual pointers to a struct. 62 - Check the length provided in the message won't exceed the buffer. 63 642. pldm_entity_association_tree_copy_root() 65 66 The implementation allocates, but gives no indication to the caller if an 67 allocation (and hence the copy) has failed. Users should migrate to 68 pldm_entity_association_tree_copy_root_check(). 69 70### Removed 71 721.

Rename and deprecate functions with the `_check` suffix 156 157 All library function return values always need to be checked. The `_check` 158 suffix is redundant, so remove it. Migration to the non-deprecated 159 equivalents without the `_check` suffix can be performed using 160 `scripts/ apply-renames` and the [clang-rename][] configurations under 161 `evolutions/` 162 163 The deprecated functions: 164 165 - `get_fru_record_by_option_check()` 166 - `pldm_bios_table_append_pad_checksum_check()` 167 - `pldm_bios_table_attr_entry_enum_decode_def_num_check()` 168 - `pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()` 169 - `pldm_bios_table_attr_entry_enum_decode_pv_num_check()` 170 - `pldm_bios_table_attr_entry_enum_encode_check()` 171 - `pldm_bios_table_attr_entry_integer_encode_check()` 172 - `pldm_bios_table_attr_entry_string_decode_def_string_length_check()` 173 - `pldm_bios_table_attr_entry_string_encode_check()` 174 - `pldm_bios_table_attr_value_entry_encode_enum_check()` 175 - `pldm_bios_table_attr_value_entry_encode_integer_check()` 176 - `pldm_bios_table_attr_value_entry_encode_string_check()` 177 - `pldm_bios_table_string_entry_decode_string_check()` 178 - `pldm_bios_table_string_entry_encode_check()` 179 - `pldm_entity_association_pdr_add_check()` 180 - `pldm_entity_association_pdr_add_from_node_check()` 181 - `pldm_pdr_add_check()` 182 - `pldm_pdr_add_fru_record_set_check()` 183 184[clang-rename]: https://clang.llvm.org/extra/clang-rename.html 185 1862. `decode_get_pdr_repository_info_resp()` 187 188 Users should move to `decode_get_pdr_repository_info_resp_safe()` which 189 eliminates the opportunity for buffer overruns when extracting objects from 190 the message. 191 1923. `decode_get_pdr_resp()` 193 194 Users should move to `decode_get_pdr_resp_safe()` which reduces the 195 invocation tedium and improves memory safety over `decode_get_pdr_resp()`. 196 197### Removed 198 1991.
