Updated: OpenSSH-5.7p1-1


I've just updated the Cygwin version of OpenSSH to 5.7p1-1.

This is a new major upstream release.  The Cygwin release is created
from the vanilla sources.

The official release message of 5.7p1:

====================================================================
OpenSSH 5.7 has just been released. It will be available from the
mirrors listed at http://www.openssh.com/ shortly.

OpenSSH is a 100% complete SSH protocol version 1.3, 1.5 and 2.0
implementation and includes sftp client and server support.

Once again, we would like to thank the OpenSSH community for their
continued support of the project, especially those who contributed
code or patches, reported bugs, tested snapshots or donated to the
project. More information on donations may be found at:
http://www.openssh.com/donations.html

Changes since OpenSSH 5.6
=========================

Features:

 * 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 - an ECDSA key may be certified, and an ECDSA key may act
   as a CA to sign certificates.

   ECDH in a 256 bit curve field is the preferred key agreement
   algorithm when both the client and server support it. ECDSA host
   keys are preferred when learning a host's keys for the first time,
   or can be learned using ssh-keyscan(1).

 * 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.
   bz#1733

 * sftp(1): the sftp client is now significantly faster at performing
   directory listings, using OpenBSD glob(3) extensions to preserve
   the results of stat(3) operations performed in the course of its
   execution rather than performing expensive round trips to fetch
   them again afterwards.

 * 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. (also fixes bz#1711)

 * 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). bz#1147

BugFixes:

 * ssh(1)/ssh-agent(1): honour $TMPDIR for client xauth and ssh-agent
   temporary directories. bz#1809

 * ssh(1): avoid NULL deref on receiving a channel request on an unknown
   or invalid channel; bz#1842

 * sshd(8): remove a debug() that pollutes stderr on client connecting
   to a server in debug mode; bz#1719

 * 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; bz#1837

 * sftp-server(8): umask should be parsed as octal

 * sftp(1): escape '[' in filename tab-completion

 * ssh(1): Typo in confirmation message.  bz#1827

 * 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;
   bz#1812

 * Support building against openssl-1.0.0a

Portable OpenSSH Bugfixes:

 * Use mandoc as preferred manpage formatter if it is present, followed
   by nroff and groff respectively.

 * sshd(8): Relax permission requirement on btmp logs to allow group
   read/write

 * bz#1840: fix warning when configuring --with-ssl-engine

 * sshd(8): Use correct uid_t/pid_t types instead of int. bz#1817

 * sshd(8): bz#1824: Add Solaris Project support.

 * sshd(8): Check is_selinux_enabled for exact return code since it can
   apparently return -1 under some conditions.
