Import OpenSSH-5.8p1.
* Fix vulnerability in legacy certificate signing introduced in
OpenSSH-5.6.
* 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.
* sftp(1)/sftp-server(8): add a protocol extension to support a hard
link operation. It is available through the "ln" command in the
client. The old "ln" behaviour of creating a symlink is available
using its "-s" option or through the preexisting "symlink" command
* scp(1): Add a new -3 option to scp: Copies between two remote hosts
are transferred through the local host. Without this option the
data is copied directly between the two remote hosts.
* ssh(1): automatically order the hostkeys requested by the client
based on which hostkeys are already recorded in known_hosts. This
avoids hostkey warnings when connecting to servers with new ECDSA
keys, since these are now preferred when learning hostkeys for the
first time.
* ssh(1)/sshd(8): add a new IPQoS option to specify arbitrary
TOS/DSCP/QoS values instead of hardcoding lowdelay/throughput.
* ssh(1): "atomically" create the listening mux socket by binding it on
a temporary name and then linking it into position after listen() has
succeeded. This allows the mux clients to determine that the server
socket is either ready or stale without races. stale server sockets
are now automatically removed.
* ssh(1)/sshd(8): add a KexAlgorithms knob to the client and server
configuration to allow selection of which key exchange methods are
used by ssh(1) and sshd(8) and their order of preference.
* sftp(1)/scp(1): factor out bandwidth limiting code from scp(1) into
a generic bandwidth limiter that can be attached using the atomicio
callback mechanism and use it to add a bandwidth limit option to
sftp(1).
BugFixes:
* ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
temporary directories.
* ssh(1): avoid NULL deref on receiving a channel request on an unknown
or invalid channel;
* sshd(8): remove a debug() that pollutes stderr on client connecting
to a server in debug mode
* scp(1): pass through ssh command-line flags and options when doing
remote-remote transfers, e.g. to enable agent forwarding which is
particularly useful in this case;
* sftp-server(8): umask should be parsed as octal
* sftp(1): escape '[' in filename tab-completion
* ssh(1): Typo in confirmation message.
* sshd(8): prevent free() of string in .rodata when overriding
AuthorizedKeys in a Match block
* sshd(8): Use default shell /bin/sh if $SHELL is ""
* ssh(1): kill proxy command on fatal() (we already killed it on
clean exit);
* ssh(1): install a SIGCHLD handler to reap expiried child process;
* sshd(8): Use correct uid_t/pid_t types instead of int.
