%%%%%%%%%%%%%%%%%%%%%%%%%%% = NOTES ON RELEASE 4.1.3s = %%%%%%%%%%%%%%%%%%%%%%%%%%%

Beginning with the ION 4.1.3s release, ION will include support for compilation with Mbed TLS cryptographic library. ION version 4.1.3s includes support for Mbed TLS version 2.28.

To enable use of Mbed TLS cryptogrpahic library in ION, you must have already built the Mbed TLS version 2.28.x shared libraries with #define MBEDTLS_NIST_KW_C enabled (see mbedtls/include/mbedtls/config.h).

Make sure the Mbed TLS assets are installed in /usr/local/include/ and /usr/local/lib with correct permissions, or you can define alternate locations by running: ./configure --enable-crypto-mbedtls MBED_LIB_PATH=/path/to/libraries MBED_INC_PATH=/path/to/includes

To build Mbed TLS: 1. Download the Mbed-TLS 2.28.2 source code. 2. Open mbedtls-2.28.x/include/mbedtls/config.h and uncomment the line that has #define MBEDTLS_NIST_KW_C commented out by default. 3. Run the following commands: Linux and MacOS) make SHARED=1 sudo make install Windows 7) make CC="gcc -std=c99" WINDOWS_BUILD=1 SHARED=1 make CC="gcc -std=c99" WINDOWS_BUILD=1 install * NOTE: this should install things in /msys/local which is okay

To compile ION with MBEDTLS_SUITES configure with: ./configure --enable-crypto-mbedtls

To enable BPSec logging (recommended for verification of BPSec functionality and required by BPSec regression tests) use the following configuration flag: --enable-bpsec-debugging

The following code changes have been made to support this option: * Added ici/MBEDTLS_SUITES folder. * Updated configure.ac and Makefile.am to allow for linking against MBEDTLS libraries.

ION 4.1.3s provides a 'enable_manual_build.sh' script that switches ION from autoconf build system (the default) to the manual developmental build system based consisting of a Makefile at the root of ION source tree and a set of Makefiles under the directories of individual components of ION. See the online documentation for more details.

Branches included in this release:

update-4.1.3s-ion-documentation * Update ION documentation files.

update-4.1.3s-bpcounter-delivery-release * Updates the bpcounter.c program so it releases the pilot bundle.

update-4.1.3s-dtnnone-vulnerability * Addresses a vulnerability that freezes ION if a bundle with null-endpoint were injected into ION node.

update-4.1.3s-imc-pnb-extblock-crash * Fixes a vulnerability when a pnb extension block contains invalid eid (or say imc scheme for a node that does not recognize it) causing a crash of the bundle acquisition process.

update-4.1.4-test-suite * General improvements to the test scripts.

update-4.1.3s-cgrfetch * Fixes a segfault at the end of cgrfetch call.

update-4.1.3s_libmetadata_libsecypt * Includes branch update-4.1.3s_bpsec_updates and also update-4.1.3s_secfix_testfix

feature-msys2-update * Adds autoconf build process for Windows 10 using msys2 and mingw64. * This update is experimental and has not been tested against MBEDTLS_SUITES (just NULL crypto suites).

update-4.1.3s-bpcp-and-test * Support for how ion-core builds bpcp. * Creates tests that can imported into ion-core for LTP and STCP convergence layers.

4.1.3s_makefile_correction * Remove incorrect inclusions of libsecrypt and libmetadata from libbp.

update-4.1.4-extension-block-crc16 * Turn on CRC16 for all blocks.

bpsec-fixes-5-27-2024 * APL fix for a specific case where BPSec may allow a bundle to fail BIB/BCB but still be accepted. * Allow relay nodes not to have a policy.

bpsec-fix-1-June-2024 * Fix accounting issue with ZCO when using BIBE with BPSec.

update-4.1.4-ionstart-upgrade * Update start script to support syntax that allows multiple ionrc files to be specified.

update-4.1.4-bssrecv * Updates to bssrecv program and documentation.

integration-4.1.3s-util-signals-fix * Added signal handler for SIGINT to properly shut down child processes. * Added signal handler for SIGTERM for graceful termination of the process.

integration-4.1.3s-smart-file-update * Updated smart file transfer utilities with file size reporting and improved message logging.
