Subject: [ptxdist] [PATCH 3/4] dropbear: version bump 2019.78 -> 2020.79
Date: Thu, 5 Nov 2020 09:13:01 +0100 [thread overview]
Message-ID: <20201105081302.6770-4-ada@thorsis.com> (raw)
In-Reply-To: <20201105081302.6770-1-ada@thorsis.com>
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

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.
