[Unreleased]

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()

Fixes

  1. pdr: Return success for pldm_pdr_find_child_container_id_range_exclude() API

[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
