Do not throw away already open sockets for X11 forwarding if another socket
family is not available for bind()
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.
