openssh/openssh-7.7p1-hostname_changes_when_forwarding_X.patch
Tomáš Chvátal 318211936a Accepting request 737034 from home:hpjansson:branches:network
Version update to 8.1p1:
  * ssh-keygen(1): when acting as a CA and signing certificates with
    an RSA key, default to using the rsa-sha2-512 signature algorithm.
    Certificates signed by RSA keys will therefore be incompatible
    with OpenSSH versions prior to 7.2 unless the default is
    overridden (using "ssh-keygen -t ssh-rsa -s ...").
  * ssh(1): Allow %n to be expanded in ProxyCommand strings
  * ssh(1), sshd(8): Allow prepending a list of algorithms to the
    default set by starting the list with the '^' character, E.g.
    "HostKeyAlgorithms ^ssh-ed25519"
  * ssh-keygen(1): add an experimental lightweight signature and
    verification ability. Signatures may be made using regular ssh keys
    held on disk or stored in a ssh-agent and verified against an
    authorized_keys-like list of allowed keys. Signatures embed a
    namespace that prevents confusion and attacks between different
    usage domains (e.g. files vs email).
  * ssh-keygen(1): print key comment when extracting public key from a
    private key.
  * ssh-keygen(1): accept the verbose flag when searching for host keys
    in known hosts (i.e. "ssh-keygen -vF host") to print the matching
    host's random-art signature too.
  * All: support PKCS8 as an optional format for storage of private
    keys to disk.  The OpenSSH native key format remains the default,
    but PKCS8 is a superior format to PEM if interoperability with
    non-OpenSSH software is required, as it may use a less insecure
    key derivation function than PEM's.
- Additional changes from 8.0p1 release:
  * scp(1): Add "-T" flag to disable client-side filtering of
    server file list.
  * sshd(8): Remove support for obsolete "host/port" syntax.
