Allow "ssh -Q protocol-version" to list supported SSH
protocol versions. Useful for detecting builds without SSH v.1 support; idea
and ok markus@
|
|
Add a ssh_config HostbasedKeyType option to control which
host public key types are tried during hostbased authentication.
This may be used to prevent too many keys being sent to the server,
and blowing past its MaxAuthTries limit.
bz#2211 based on patch by Iain Morgan; ok markus@
|
|
correct description of UpdateHostKeys in ssh_config.5 and
add it to -o lists for ssh, scp and sftp; pointed out by jmc@
|
|
add fingerprinthash to the options list;
|
|
Add FingerprintHash option to control algorithm used for
key fingerprints. Default changes from MD5 to SHA256 and format from hex to
base64.

Tweak config reparsing with host canonicalisation
Make the second pass through the config files always run when
hostname canonicalisation is enabled.
Add a "Match canonical" criteria that allows ssh_config Match
blocks to trigger only in the second config pass.
Add a -G option to ssh that causes it to parse its configuration
and dump the result to stdout, similar to "sshd -T"
Allow ssh_config Port options set in the second config parse
phase to be applied (they were being ignored).

[ssh.1 ssh.c]
- put -Q in the right place
- Ar was a poor choice for the arguments to -Q. i've chosen an
admittedly equally poor Cm, at least consistent with the rest
of the docs. also no need for multiple instances
- zap a now redundant Nm
- usage() sync
|
|
[ssh.1 ssh.c]
improve -Q usage and such. One usage change is that the option is now
case-sensitive

[dh.c myproposal.h packet.c poly1305.c poly1305.h servconf.c ssh.1]
[ssh.c ssh_config.5 sshd_config.5] Add a new protocol 2 transport
cipher "chacha20-poly1305@openssh.com" that combines Daniel
Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an
authenticated encryption mode.
Inspired by and similar to Adam Langley's proposal for TLS:
http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03
but differs in layout used for the MAC calculation and the use of a
second ChaCha20 instance to separately encrypt packet lengths.
Details are in the PROTOCOL.chacha20poly1305 file.

s/canonicalise/canonicalize/ for consistency with existing spelling,
e.g. authorized_keys; pointed out by naddy@
|
|
[readconf.c readconf.h roaming_client.c ssh.1 ssh.c ssh_config.5]
[sshconnect.c sshconnect.h]
Implement client-side hostname canonicalisation to allow an explicit
search path of domain suffixes to use to convert unqualified host names
to fully-qualified ones for host key matching.
This is particularly useful for host certificates, which would otherwise
need to list unqualified names alongside fully-qualified ones (and this
causes a number of problems).

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
better performance than plain DH and DSA at the same equivalent symmetric
key length, as well as much shorter keys.
Only the mandatory sections of RFC5656 are implemented, specifically the
three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
ECDSA. Point compression (optional in RFC5656 is NOT implemented).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.
