[sshconnect2.c]
swap the last two parameters to TAILQ_FOREACH_REVERSE. matches what FreeBSD and NetBSD do.
ok millert@ mcbride@ markus@ ho@, checked to not affect ports by naddy@
[auth2-gss.c gss-genr.c gss-serv.c monitor.c monitor.h monitor_wrap.c]
[monitor_wrap.h sshconnect2.c ssh-gss.h]
replace "gssapi" with "gssapi-with-mic"; from Simon Wilkinson;
test + ok jakob.
[auth2.c auth2-gss.c auth.h compat.c compat.h gss-genr.c gss-serv-krb5.c
gss-serv.c monitor.c monitor.h monitor_wrap.c monitor_wrap.h readconf.c
readconf.h servconf.c servconf.h session.c session.h ssh-gss.h
ssh_config.5 sshconnect2.c sshd_config sshd_config.5]
support GSS API user authentication; patches from Simon Wilkinson,
stripped down and tested by Jakob and myself.
[auth2.c monitor.c sshconnect2.c auth2-krb5.c]
implement kerberos over ssh2 ("kerberos-2@ssh.com"); tested with jakob@
server interops with commercial client; ok jakob@ djm@
[sshconnect2.c]
for pubkey authentication try the user keys in the following order:
1. agent keys that are found in the config file
2. other agent keys
3. keys that are only listed in the config file
this helps when an agent has many keys, where the server might
close the connection before the correct key is used. report & ok pb@
[clientloop.c monitor.c monitor_wrap.c packet.c packet.h readconf.c]
[readconf.h serverloop.c sshconnect2.c]
rekeying bugfixes and automatic rekeying:
* both client and server rekey _automatically_
(a) after 2^31 packets, because after 2^32 packets
the sequence number for packets wraps
(b) after 2^(blocksize_in_bits/4) blocks
(see: draft-ietf-secsh-newmodes-00.txt)
(a) and (b) are _enabled_ by default, and only disabled for known
openssh versions, that don't support rekeying properly.
* client option 'RekeyLimit'
* do not reply to requests during rekeying

[clientloop.c monitor.c monitor_wrap.c packet.c packet.h readconf.c]
[readconf.h serverloop.c sshconnect2.c]
backout rekeying changes (for 3.6.1)
[kex.c kexdh.c kexgex.c kex.h sshconnect2.c sshd.c ssh-keyscan.c]
split kex into client and server code, no need to link
server code into the client; ok provos@
[sshconnect2.c]
for compression=yes, we fallback to no-compression if the server does
not support compression, vice versa for compression=no. ok mouring@
[sshconnect2.c]
extent ssh-keysign protocol:
pass # of socket-fd to ssh-keysign, keysign verfies locally used
ip-address using this socket-fd, restricts fake local hostnames
to actual local hostnames; ok stevesk@
[authfile.c authfile.h pathnames.h ssh.c sshconnect.c sshconnect.h
sshconnect1.c sshconnect2.c ssh-keysign.8 ssh-keysign.c Makefile.in]
add /usr/libexec/ssh-keysign: a setuid helper program for hostbased
authentication in protocol v2 (needs to access the hostkeys).
Note: Makefile.in untested. Will test after merge is finished.
[auth2.c auth2-chall.c channels.c channels.h clientloop.c dispatch.c]
[dispatch.h kex.c kex.h packet.c packet.h serverloop.c ssh.c]
[sshconnect2.c]
Conformance fix: we should send failing packet sequence number when
responding with a SSH_MSG_UNIMPLEMENTED message. Spotted by
yakk@yakk.dot.net; ok markus@
[packet.c packet.h sshconnect2.c]
pad using the padding field from the ssh2 packet instead of sending
extra ignore messages. tested against several other ssh servers.
[kexdh.c kexgex.c kex.h pathnames.h readconf.c servconf.h ssh.1
sshconnect1.c sshconnect2.c sshconnect.c sshconnect.h sshd.8]
get rid of known_hosts2, use it for hostkey lookup, but do not
modify.
[ssh.1 sshconnect2.c]
change preferredauthentication order to
publickey,hostbased,password,keyboard-interactive
document that hostbased defaults to no, document order
[auth-chall.c auth.h auth1.c auth2-chall.c auth2.c readconf.c
readconf.h servconf.c servconf.h sshconnect1.c sshconnect2.c sshd.c]
improved kbd-interactive support. work by per@appgate.com and me
[auth2.c compat.c sshconnect2.c]
more ssh v2 hostbased-auth interop: ssh.com >= 2.1.0 works now
(however the 2.1.0 server seems to work only if debug is enabled...)
[channels.c channels.h clientloop.c kex.c kex.h serverloop.c
sshconnect2.c sshd.c]
more robust rekeying
don't send channel data after rekeying is started.
[clientloop.c kex.c kex.h serverloop.c sshconnect2.c sshd.c]
enable server side rekeying + some rekey related clientup.
todo: we should not send any non-KEX messages after we send KEXINIT
[clientloop.c sshconnect2.c]
enable client rekeying
(1) force rekeying with ~R, or
(2) if the server requests rekeying.
works against ssh-2.0.12/2.0.13/2.1.0/2.2.0/2.3.0/2.3.1/2.4.0
[kex.c kex.h packet.c sshconnect2.c sshd.c]
undo parts of recent my changes: main part of keyexchange does not
need dispatch-callbacks, since application data is delayed until
the keyexchange completes (if i understand the drafts correctly).
add some infrastructure for re-keying.
[compat.c compat.h dh.c dh.h ssh2.h sshconnect2.c sshd.c version.h]
make dh group exchange more flexible, allow min and max group size,
okay markus@, deraadt@
[compat.c compat.h readconf.h ssh.c sshconnect1.c sshconnect2.c]
implement client side of SSH2_MSG_USERAUTH_PK_OK (test public key ->
no need to do enter passphrase or do expensive sign operations if the
server does not accept key).
[kex.c kex.h sshconnect2.c sshd.c]
generate a 2*need size (~300 instead of 1024/2048) random private
exponent during the DH key agreement. according to Niels (the great
german advisor) this is safe since /etc/primes contains strong
primes only.

1) clean up the MAC support for SSH-2
2) allow you to specify the MAC with 'ssh -m'
3) or the 'MACs' keyword in ssh(d)_config
4) add hmac-{md5,sha1}-96
