[Unreleased]

Added

  1. oem: meta: Add decode_oem_meta_file_io_write_req()

  2. oem: meta: Add decode_oem_meta_file_io_read_req()

  3. oem: meta: Add encode_oem_meta_file_io_read_resp()

  4. pdr: Add pldm_entity_association_pdr_remove_contained_entity()

  5. pdr: Add pldm_pdr_remove_fru_record_set_by_rsi()

  6. pldm_entity_association_tree_copy_root_check()

  7. oem: ibm: Add topology related state set and enum

  8. base: Add size and buffer macros for struct pldm_msg

    Together these macros reduce the need for use of reinterpret_cast<>() in C++.

Changed

  1. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()

    pldm_bios_table_iter_is_end() now returns true if the provided argument is NULL.

  2. Register assignment for parameters of a number of APIs changed with increased scrutiny on their implementations.

    • decode_entity_auxiliary_names_pdr()
    • decode_get_state_sensor_readings_resp()
    • decode_oem_meta_file_io_req()
    • decode_platform_event_message_req()
    • decode_platform_event_message_resp()
    • decode_sensor_op_data()
    • encode_get_state_effecter_states_resp()
    • encode_state_effecter_pdr()
    • encode_state_sensor_pdr()
    • pldm_bios_table_append_pad_checksum()
    • pldm_bios_table_attr_value_entry_encode_enum()
    • pldm_bios_table_attr_value_entry_encode_string()
    • pldm_pdr_find_record()
    • pldm_pdr_get_next_record()

  3. platform: Support PLDM_CPER_EVENT in encode_platform_event_message_req()

  4. dsp: firmware_update: Bounds check decode_downstream_device_parameter_table_entry_versions()

    The additional bounds-checking required the addition of further length parameters.

Deprecated

  1. oem: meta: Deprecate decode_oem_meta_file_io_req()

    Users should switch to decode_oem_meta_file_io_write_req(). Modify this function to make it safer.

    Modification:

    • The meaning of the returned result.
    • Change parameters from individual pointers to a struct.
    • Check the length provided in the message won't exceed the buffer.

  2. pldm_entity_association_tree_copy_root()

    The implementation allocates, but gives no indication to the caller if an allocation (and hence the copy) has failed. Users should migrate to pldm_entity_association_tree_copy_root_check().

  3. The following APIs are deprecated as unsafe due to various unfixable CWE violations:

    • CWE-129: Improper Validation of Array Index

      • encode_get_bios_current_value_by_handle_resp()
      • encode_get_bios_table_resp()
      • encode_get_file_table_resp()
      • encode_get_version_resp()
      • pldm_bios_table_attr_entry_enum_decode_def_indices()
      • pldm_bios_table_attr_entry_enum_decode_def_num()
      • pldm_bios_table_attr_find_by_handle()
      • pldm_bios_table_attr_find_by_string_handle()
      • pldm_bios_table_attr_value_find_by_handle()
      • pldm_bios_table_iter_create()
      • pldm_bios_table_iter_is_end()
      • pldm_bios_table_string_find_by_handle()
      • pldm_bios_table_string_find_by_string()

    • CWE-617: Reachable Assertion

      • pldm_entity_association_tree_copy_root()

    • CWE-789: Memory Allocation with Excessive Size Value

      • decode_oem_meta_file_io_req()

    • CWE-823: Use of Out-of-range Pointer Offset

      • encode_fru_record()
      • encode_get_pdr_resp()
      • pldm_bios_table_attr_entry_enum_encode_length()

Removed

    • pldm_bios_table_attr_value_entry_encode_integer_check()
    • pldm_bios_table_attr_value_entry_encode_string_check()
    • pldm_bios_table_string_entry_decode_string_check()
    • pldm_bios_table_string_entry_encode_check()
    • pldm_entity_association_pdr_add_check()
    • pldm_entity_association_pdr_add_from_node_check()
    • pldm_pdr_add_check()
    • pldm_pdr_add_fru_record_set_check()

Fixed

  1. dsp: bios_table: Null check for pldm_bios_table_iter_is_end()

    Avoid a caller-controlled NULL pointer dereference in the library implementation.

  2. platform: fix encode/decode_poll_for_platform_event_message_req

    Update checking of TransferOperationFlag and eventIDToAcknowledge to follow spec.

  3. platform: Fix checking eventIDToAcknowledge

    As the event receiver sends PollForPlatformEventMessage with the tranferFlag is AcknowledgementOnly, the value eventIDToAcknowledge should be the previously retrieved eventID (from the PLDM terminus).

  5. dsp: platform: Bounds check encode_sensor_state_pdr()

  6. dsp: platform: Bounds check encode_state_effecter_pdr()

  12. oem: ibm: platform: Bounds check encode_bios_attribute_update_event_req()

  13. dsp: fru: Bounds check encode_get_fru_record_by_option_resp()

  14. dsp: fru: Bounds check encode_fru_record()

  15. dsp: bios: Bounds check encode_set_bios_table_req()

  16. dsp: bios: Bounds check encode_set_bios_attribute_current_value_req()

Changed

  1. pdr: Stabilise related decode_entity_auxiliary_names_pdr() APIs

  2. platform: Rework decode/encode_pldm_message_poll_event_data() APIs

  3. platform: Stabilise decode_pldm_message_poll_event_data() APIs

  4. ABI break for decode_sensor_op_data()

    Applying LIBPLDM_CC_NONNULL to the internal msgbuf APIs caused abi-compliance-checker to flag a change in the register containing the parameter previous_op_state.

  6. oem: meta: Stabilise decode_oem_meta_file_io_write_req() API

  7. oem: meta: Stabilise decode_oem_meta_file_io_read_req() API

  8. oem: meta: Stabilise encode_oem_meta_file_io_read_resp() API

Deprecated

  1. Rename and deprecate functions with the _check suffix

    All library function return values always need to be checked. The _check suffix is redundant, so remove it. Migration to the non-deprecated equivalents without the _check suffix can be performed using scripts/ apply-renames and the clang-rename configurations under evolutions/

    The deprecated functions:

    • get_fru_record_by_option_check()
    • pldm_bios_table_append_pad_checksum_check()
    • pldm_bios_table_attr_entry_enum_decode_def_num_check()
    • pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()
    • pldm_bios_table_attr_entry_enum_decode_pv_num_check()
    • pldm_bios_table_attr_entry_enum_encode_check()
    • pldm_bios_table_attr_entry_integer_encode_check()
    • pldm_bios_table_attr_entry_string_decode_def_string_length_check()
    • pldm_bios_table_attr_entry_string_encode_check()
    • pldm_bios_table_attr_value_entry_encode_enum_check()
    • pldm_bios_table_attr_value_entry_encode_integer_check()
    • pldm_bios_table_attr_value_entry_encode_string_check()
    • pldm_bios_table_string_entry_decode_string_check()
    • pldm_bios_table_string_entry_encode_check()
    • pldm_entity_association_pdr_add_check()
    • pldm_entity_association_pdr_add_from_node_check()
    • pldm_pdr_add_check()
    • pldm_pdr_add_fru_record_set_check()

  1. decode_get_pdr_repository_info_resp()

    Users should move to decode_get_pdr_repository_info_resp_safe() which eliminates the opportunity for buffer overruns when extracting objects from the message.

  2. decode_get_pdr_resp()

    Users should move to decode_get_pdr_resp_safe() which reduces the invocation tedium and improves memory safety over decode_get_pdr_resp().

Removed

  1. IBM OEM header compatibility symlinks.

    Anyone left using the deprecated paths can migrate using the coccinelle patch at evolutions/current/oem-ibm-header-compat.cocci.

Fixed

  1. requester: instance-id: Release read lock on conflict
  2. pdr: Error propagation for pldm_entity_association_pdr_add_from_node_with_record_handle()

  8. pdr: Document preconditions for trivial accessor functions

    A trivial accessor function is one that exposes properties of an object in a way can't result in an error, beyond passing an invalid argument to the function. For APIs meeting this definition we define a precondition that struct pointers must point to valid objects to avoid polluting the function prototypes. The following APIs now have this precondition explicitly defined:

    • pldm_entity_extract()
    • pldm_entity_get_parent()
    • pldm_entity_is_exist_parent()
    • pldm_entity_is_node_parent()
    • pldm_is_current_parent_child
    • pldm_is_empty_entity_assoc_tree()
    • pldm_pdr_get_record_count()

    pldm_pdr_add_fru_record_set() is deprecated by this change. Users of pldm_pdr_add_fru_record_set() should migrate to pldm_pdr_add_fru_record_set_check()

Removed

  1. bios_table: Remove deprecated APIs sanitized by assert():

    • pldm_bios_table_string_entry_encode()
    • pldm_bios_table_string_entry_decode_string()
    • pldm_bios_table_attr_entry_enum_encode()
    • pldm_bios_table_attr_entry_enum_decode_pv_num()
    • pldm_bios_table_attr_entry_enum_decode_def_num()
    • pldm_bios_table_attr_entry_enum_decode_pv_hdls()
    • pldm_bios_table_attr_entry_string_encode()
    • pldm_bios_table_attr_entry_string_decode_def_string_length()

Fixed

  1. pdr: Return success for pldm_pdr_find_child_container_id_range_exclude() API
  2. pdr: Rework pldm_pdr_find_container_id_range_exclude() API
  3. transport: mctp-demux: Don't test socket for non-zero value
  4. requester: Return PLDM_REQUESTER_OPEN_FAIL from pldm_open() on error
  5. pdr: pldm_pdr_fru_record_set_find_by_rsi(): Document reality of return
  6. transport: Fix possible NULL ptr deref in pldm_socket_sndbuf_init()
  7. abi: Update to remove pldm_close() from reference dumps
  8. bios_table: Annotate pldm_bios_table_attr_value_entry_encode_integer()

[0.3.0] - 2023-06-23

Added

  1. Add encode/decode pldmMessagePollEvent data
  2. README: Add a section on working with libpldm
  3. pdr: Introduce remote_container_id and associated APIs
  4. pdr: Add APIs for creating and locating remote PDRs
  5. pdr: Add pldm_pdr_find_last_in_range()
  6. pdr: Add pldm_entity_association_pdr_add_from_node_with_record_handle()
  7. pdr: Add pldm_pdr_find_container_id_range_exclude()

Changed

  1. include: Move installed transport.h under libpldm/

  2. libpldm: Explicit deprecated, stable and testing ABI classes

  3. meson: Reduce strength of oem-ibm requirements from enabled to allowed

    The oem-ibm feature is now enabled by the default meson configuration, for CI purposes. oem-ibm is still disabled by default in the libpldm bitbake recipe:

    https://github.com/openbmc/openbmc/blob/master/meta-phosphor/recipes-phosphor/libpldm/libpldm_git.bb#L10

    To disable oem-ibm in your development builds, pass -Doem-ibm=disabled when invoking meson setup

  4. bios_table: Relax pldm_bios_table_string_entry_decode_string_check()

  5. bios_table: Relax pldm_bios_table_attr_entry_enum_decode_pv_hdls_check()

Deprecated

  1. bios_table: Deprecate APIs with arguments sanitized using assert()

    C provides enough foot-guns without us encoding them into library APIs. Specifically, deprecate the following in favour of their *_check() variants which ensure assertions won't fail or otherwise invoke UB:

    • pldm_bios_table_string_entry_encode()
    • pldm_bios_table_string_entry_decode_string()
    • pldm_bios_table_attr_entry_enum_encode()
    • pldm_bios_table_attr_entry_enum_decode_pv_num()
    • pldm_bios_table_attr_entry_enum_decode_def_num()
    • pldm_bios_table_attr_entry_enum_decode_pv_hdls()
    • pldm_bios_table_attr_entry_string_encode()
    • pldm_bios_table_attr_entry_string_decode_def_string_length()

Removed

  1. libpldm: Remove the requester-api option

Fixed

  1. requester: Make pldm_open() return existing fd
  2. transport: Prevent sticking in waiting for response
  3. transport: Match on response in pldm_transport_send_recv_msg()
  4. requester: Add check before accessing hdr in pldm_recv()
  5. bios_table: pldm_bios_table_attr_entry_string_info_check() NULL deref
