last would win (which is the opposite to how the config is supposed to work).
While there, make the ssh_config parsing more like sshd_config.

Historicallly, hpdelim accepted ":" or "/" as a port delimiter between
hosts (or addresses) and ports. These days most of the uses for "/"
are no longer accepted, so there are several places where it checks the
delimiter to disallow it. Make hpdelim accept only ":" and use hpdelim2
in the other cases. ok djm@

favour of KbdInteractiveAuthentication. The former is what was in SSHv1, the
latter is what is in SSHv2 (RFC4256) and they were treated as somewhat but
not entirely equivalent. We retain the old name as deprecated alias so
config files continue to work and a reference in the man page for people
looking for it.

similar to the previous commit, this switches sshd_config parsing to
the newer tokeniser. Config parsing will be a little stricter wrt
quote correctness and directives appearing without arguments.

BROKEN_MMAP is no longer defined since commit
1cfd5c06ef ("Remove portability support for mmap")
this commit also removed other HAVE_MMAP user. I didn't find anything
that defines HAVE_MMAP. The check does not trigger because compression
on server side is by default COMP_DELAYED (2) so it never triggers.
Remove remaining HAVE_MMAP and BROKEN_MMAP bits.

This adds a "verify-required" authorized_keys flag and a corresponding
sshd_config option that tells sshd to require that FIDO keys verify the
user identity before completing the signing/authentication attempt.
Whether or not user verification was performed is already baked into the
signature made on the FIDO token, so this is just plumbing that flag
through and adding ways to require it.

This directive has a single valid option "no-touch-required" that

a security key signature was made (usually by the user touching the

The previous revert enabled case-insensitive user names again. This
patch implements the case-insensitive user and group name matching.
To allow Unicode chars, implement the matcher using wchar_t chars in
Cygwin-specific code. Keep the generic code changes as small as possible.

host/port was added in 2001 as an alternative to host:port syntax for
the benefit of IPv6 users. These days there are establised standards
for this like [::1]:22 and the slash syntax is easily mistaken for CIDR
notation, which OpenSSH now supports for some things. Remove the slash
notation from ListenAddress and PermitOpen. bz#2335, patch from jjelen
