-Subject: Fix y2038 issues with time_t conversion
-
-These changes were identified by building with and without
--D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64
-on 32-bit arm, logging warnings to files.
--Wconversion was added to CFLAGS in both builds.
-
-Then a "diff -I Wconversion log1 log2" shows new warnings that appear
-with the 64-bit time_t. There are a few false positives that have been
-fixed for quietness.
-
-struct logininfo and struct wtmp are still problematic, those will
-need to be handled by libc.

-Subject: Disable rsa signatures when no rsa hostkey
-
-Otherwise Dropbear will offer RSA as a hostkey signature option, but the
-session will exit with an assertion or NULL pointer dereference once
-that algorithm is negotiated.
-
-This likely regressed in 2020.79 when signature vs key type enums were
-split, for rsa-sha256.
-
-Fixes #219 on github

-Subject: Remove SO_LINGER
-
-It could cause channels to take up to 5 seconds to close(), which would block
-the entire process. On busy TCP forwarding sessions this would result in
-channels seeming stuck and new connections not being accepted.
-
-We don't need to monitor for flushing failures since we can't report errors, so
-SO_LINGER wasn't useful.
-
-Thanks to GektorUA for reporting and testing
-
-Fixes #230

-Subject: dropbearkey.c Ignore unsupported command line options
-
-To generate non interactively a key with OpenSSH the simplest command is:
-
-ssh-keygen -t ed25519 -q -N '' -f ~/.ssh/id_ed25519
-
-The command has two options -q quiet and -N passphrase which aren't supported by the dropbearkey.
-
-To improve interoperability add explicit ignoring of the -q and -N with empty passphrase.
-Also ignore the -v even if the DEBUG_TRACE is not set.

-Subject: Don't try to shutdown() a pty
-
-shutdown() of a pty doesn't work (ENOTSOCK), so we should close
-it instead.
-
-This will ensure that PTY controlling terminals are closed when a
-session exits, including when multiple sessions run over a single SSH
-connection.  In the normal case of a single session, the PTY controlling
-terminal would be closed when the Dropbear server process exits anyway.
-
-This possibly fixes #264 on github
-
-It is possible that there could be subtle changes to PTY flushing
-behaviour, though nothing caught by tests at present.
