[krl.c krl.h PROTOCOL.krl]
add support for Key Revocation Lists (KRLs). These are a compact way to
represent lists of revoked keys and certificates, taking as little as
a single bit of incremental cost to revoke a certificate by serial number.
KRLs are loaded via the existing RevokedKeys sshd_config option.

Fixes logging of partial authentication when privsep is enabled
Previously, we recorded "Failed xxx" since we reset authenticated before
calling auth_log() in auth2.c. This adds an explcit "Partial" state.
Add a "submethod" to auth_log() to report which submethod is used
for keyboard-interactive.
Fix multiple authentication when one of the methods is
keyboard-interactive.

another specified via a new AuthorizedKeysCommandUser option.

allow AuthorizedKeysFile to specify multiple files, separated by spaces.
Bring back authorized_keys2 as a default search path (to avoid breaking
existing users of this file), but override this in sshd_config so it will
be no longer used on fresh installs. Maybe in 2015 we can remove it
entierly :)

[auth-options.c auth-options.h auth.c auth.h auth2-pubkey.c]
[key.c servconf.c servconf.h sshd.8 sshd_config.5]
add some optional indirection to matching of principal names listed
in certificates. Currently, a certificate must include the a user's name
to be accepted for authentication. This change adds the ability to
specify a list of certificate principal names that are acceptable.
When authenticating using a CA trusted through ~/.ssh/authorized_keys,
this adds a new principals="name1[,name2,...]" key option.
For CAs listed through sshd_config's TrustedCAKeys option, a new config
option "AuthorizedPrincipalsFile" specifies a per-user file containing
the list of acceptable names.
If either option is absent, the current behaviour of requiring the
username to appear in principals continues to apply.
These options are useful for role accounts, disjoint account namespaces
and "user@realm"-style naming policies in certificates.

be used to drop privilege to; fixes Solaris GSSAPI crash reported by
Magnus Abrante; suggestion and feedback dtucker@
NB. this change will require that the privilege separation user must
exist on all the time, not just when UsePrivilegeSeparation=yes
loginsuccess on AIX immediately after authentication to clear the failed
login count. Previously this would only happen when an interactive
session starts (ie when a pty is allocated) but this means that accounts
that have primarily non-interactive sessions (eg scp's) may gradually
accumulate enough failures to lock out an account. This change may have
a side effect of creating two audit records, one with a tty of "ssh"
corresponding to the authentication and one with the allocated pty per
interactive session.
[sshd.c servconf.h servconf.c sshd_config.5 auth.c]
Add support for conditional directives to sshd_config via a "Match"
keyword, which works similarly to the "Host" directive in ssh_config.
Lines after a Match line override the default set in the main section
if the condition on the Match line is true, eg
AllowTcpForwarding yes
Match User anoncvs
AllowTcpForwarding no
will allow port forwarding by all users except "anoncvs".
Currently only a very small subset of directives are supported.
