Noteworthy changes (not all options accessible through ptxdist menu): - added support for ed25519 hostkeys and authorized_keys - added support for chacha20-poly1305 authenticated cipher - added support for and rsa-sha2 signatures - disabled some options by default (kconfig defaults adapted accordingly) - fix idle detection clashing with keepalives - scp fix for CVE-2018-20685 where a server could modify name of output files - Call fsync() is called on parent directory when writing key files to ensure they are flushed
One especially important change: > Use getrandom() call on Linux to ensure sufficient entropy has been > gathered at startup. Dropbear now avoids reading from the random > source at startup, instead waiting until the first connection. It is > possible that some platforms were running without enough entropy > previously, those could potentially block at first boot generating > host keys. The dropbear "-R" option is one way to avoid that. On older toolchains/kernel headers/kernels without getrandom() support, dropbear should behave like before. The curve25519 implementation was replaced with the one by TweetNaCl, which induced a change in 'LICENSE' summary. The old implementation was licensed BSD-3-Clause and the new is public domain. The bundled libtommath changed its license from dual license (public domain || WTFPL) to 'Unlicense' which is also a public domain license, but with a differently worded license text and an actual SPDX identifier.
