Handles CVE-2025-47203
SHA1 algorithms were removed by default, so patch for disabling it was
removed together with its package option. Doing it with conditional
patch was anyway a bad design. If someone still needs it, it should be
done via sed command on the config file.
Refreshed remaining patches.
Added patch to fix regression of the CVE fix.

Just like the "init" version this script, pass $DROPBEAR_RSAKEY_ARGS to the
'dropbearkey' program when generating a host key.
This allows to speed up SSH connections on read-only root systems by adding
the line DROPBEAR_RSAKEY_ARGS="-s 1024" into /etc/default/dropbear.

Changelog:
=========
- Fix failure on concurrent channel open/close.
- Print remote host after "Login attempt for nonexistent user" log entry to
assist fail2ban.
- Dropbear now exits with exit status 0 on SIGINT/SIGTERM. This is a more
graceful behaviour for "systemctl stop dropbear".
- New IDENT_VERSION_PART config allows customising some of the SSH version
string.
- Fix building SK_KEYS with just one of ECDSA or ED25519
- Fix dbclient "-m help" and "-c help" without a hostname.
- Remove fprintf/gettimeofday from sigchld handler when running with
verbose trace enabled.
- Improved configure help output
- Compile fix for GNU Hurd
- Support running test_aslr without venv
- Compilation fixes for older compilers, and better build tests
- Update some test infrastructure versions of python packages,
github actions, and github runner OSes

0007-Fix-X11-build-failure-use-DROPBEAR_PRIO_LOWDELAY.patch
removed since it's included in 2022.83
Changelog:
==========
- Disable DROPBEAR_DSS by default
- Added DROPBEAR_RSA_SHA1 option to allow disabling sha1 rsa signatures.
- Add option for requiring both password and pubkey (-t)
- Add 'no-touch-required' and 'verify-required' options for sk keys
DROPBEAR_SK_KEYS config option now replaces separate DROPBEAR_SK_ECDSA
and DROPBEAR_SK_ED25519 options.
- Add 'permitopen' option for authorized_keys to restrict forwarded ports
- Added LTM_CFLAGS configure argument to set flags for building
bundled libtommath. This also restores the previous arguments used
in 2020.81 (-O3 -funroll-loops). That gives a big speedup for RSA
key generation, which regressed in 2022.82.
There is a tradeoff with code size, so -Os can be used if required.
- Add '-z' flag to disable setting QoS traffic class. This may be necessary
to work with broken networks or network drivers, exposed after changes to use
AF21 in 2022.82
- Allow overriding user shells with COMPAT_USER_SHELLS
- Improve permission error message
- Remove HMAC_MD5 entirely

Where we have images with PAM+systemd, serial login can be extremely
slow. The load generated by key generation does slow down the rest
of the boot process.
Lower the priority level of these systemd services, since we'd
prefer to have the rest of the system boot more effectively.
This doesn't "solve" the slow systemd boot issues but does help.

The origins of the patch date back to early 2005 (prior to the start
of git history in oe-core) to fix a hardcoded limit on the maximum
size of remote host keys:
http://familiar.handhelds.narkive.com/b1VGg2bI/problem-w-dropbear-ssh
The hardcoded limit was fixed upstream in dropbear 0.47:
736f370dce
The patch has therefore been obsolete since then. It went unnoticed
until now as the patch has continued to apply - it modifies a value
which is not used.

Previously, when dropbear was started via its init script, relocation
of DROPBEAR_RSAKEY_DIR to support read-only rootfs was handled at
run time from within the init script.
Update the init script to take advantage of the read-only rootfs
config setup by read_only_rootfs_hook() and therefore be consistent
with startup under systemd (where relocation of DROPBEAR_RSAKEY_DIR
is handled by the read_only_rootfs_hook() at build time).

The patch tool will apply patches by default with "fuzz", which is where if the
hunk context isn't present but what is there is close enough, it will force the
patch in.
Whilst this is useful when there's just whitespace changes, when applied to
source it is possible for a patch applied with fuzz to produce broken code which
still compiles (see #10450). This is obviously bad.
We'd like to eventually have do_patch() rejecting any fuzz on these grounds. For
that to be realistic the existing patches with fuzz need to be rebased and
reviewed.

To prevent build failures when using system libtom libraries and
linking with --as-needed, LIBTOM_LIBS should be in the order
-ltomcrypt -ltommath, not the other way around, ie libs should be
prepended to LIBTOM_LIBS as they are found, not appended.
Note that LIBTOM_LIBS is not used when linking with the bundled
libtom libs.

This patch adds DROPBEAR_RSAKEY_ARGS and DROPBEAR_DSSKEY_ARGS optional
parameters to /etc/default/dropbear. The contents are simply passed to
the 'dropbearkey' program when generating a host key.
The default keysize for RSA is currently 2048 bits. It takes a CortexA9
running at 700MHz between 4 and 10 seconds to calculate a keypair. The
board boots Linux in about a second, but you have to wait for several
seconds because of the keypair generation. This patch allows one to put
the line DROPBEAR_RSAKEY_ARGS="-s 1024" into /etc/default/dropbear, and
have a host key generated in about 0.2 seconds on the same CPU. This is
particulary useful for read-only rootfs systems which generate a key on
each boot.

Openssh now installs the sftp-server binary as /usr/libexec/sftp-server,
whereas the dropbear recipe assumes a different path.
Dropbear uses the correct path by default, so it's no longer necessary
to override SFTPSERVER_PATH via CFLAGS.
This fixes SFTP access to systems using dropbear as the SSH server.
