Check out the git tag OTP-27.3.4.4, and build a full OTP system including documentation. Apply one or more applications from this build as patches to your installation using the ‘otp_patch_apply’ tool. For information on install requirements, see descriptions for each application version below.

diameter-2.4.1.1

The diameter-2.4.1.1 application can be applied independently of other applications on a full OTP 27 installation.

Fixed Bugs and Malfunctions

  • Added documentation about ‘proxy’ and ‘resend’ options in diameter:handle_request/3

    Own Id: OTP-19768
    Related Id(s): GH-10150, PR-10182

Full runtime dependencies of diameter-2.4.1.1

erts-10.0, kernel-3.2, ssl-9.0, stdlib-5.0

erts-15.2.7.3

The erts-15.2.7.3 application can be applied independently of other applications on a full OTP 27 installation.

Fixed Bugs and Malfunctions

  • Fixed the erl documentation of the default timewarp mode used.

    Own Id: OTP-19790
    Related Id(s): PR-9970

  • The erlang:suspend_process() BIFs failed to suspend processes currently executing on dirty schedulers.

    Own Id: OTP-19799
    Related Id(s): PR-10241

  • When multiple processes called the same fun whose defining module was not loaded, a badfun exception could sometimes occur in one of the calling processes. This would only happen with the JIT runtime system.

    Own Id: OTP-19803
    Related Id(s): PR-10257

Full runtime dependencies of erts-15.2.7.3

kernel-9.0, sasl-3.3, stdlib-4.1

ssl-11.2.12.3

Note! The ssl-11.2.12.3 application cannot be applied independently of other applications on an arbitrary OTP 27 installation.

   On a full OTP 27 installation, also the following runtime
   dependency has to be satisfied:
   -- public_key-1.16.4 (first satisfied in OTP 27.1.3)

Fixed Bugs and Malfunctions

  • Fixed so that sending of application data will adhere to max_fragment_length. This was broken in OTP-27 release by an optimization.

    Own Id: OTP-19774
    Related Id(s): GH-10191, PR-10201

  • Assert that hello extensions are unique and send an illegal parameter alert if they are not.

    Own Id: OTP-19791
    Related Id(s): PR-10245

  • Avoid sending an internal message to the user process in conjunction with handling a key update.

    Own Id: OTP-19806
    Related Id(s): PR-10274

  • Graceful error handling added in negative test scenario.

    Own Id: OTP-19813
    Related Id(s): PR-10284

  • Handle duplicate change_cipher_spec message with an unexpected message alert instead of failing later in corrupted state.

    Own Id: OTP-19818
    Related Id(s): PR-10296

  • Make sure TLS-1.3 protocol spec is followed, that is psk-hello extension is guaranteed to be included as the last extension in the list of client hello extensions and internal hello message truncation in handshake history is handled correctly, the previous handling could cause interoperability issues.
