[clientloop.c clientloop.h ssh.c]
bz#1232: ensure that any specified LocalCommand is executed after the
tunnel device is opened. Also, make failures to open a tunnel device
fatal when ExitOnForwardFailure is active.

openbsd-compat/bsd-poll.{c,h} openbsd-compat/openbsd-compat.h]
Add an implementation of poll() built on top of select(2). Code from
OpenNTPD with changes suggested by djm. ok djm@
[atomicio.c]
if the fd passed to atomicio/atomiciov() is non blocking, then poll() to
avoid a spin if it is not yet ready for reading/writing; ok dtucker@
[ssh.c]
when waiting for the multiplex exit status, read until the master end
writes an entire int of data *and* closes the client_fd; fixes mux
regression spotted by dtucker, ok dtucker@
USE_BUILTIN_RIJNDAEL compat goop to openssl-compat.h so it can be
shared with umac.c. Allows building with OpenSSL 0.9.5 again including
umac support. With tim@ djm@, ok djm.
[ssh.c ssh.1]
Add "-K" flag for ssh to set GSSAPIAuthentication=yes and
GSSAPIDelegateCredentials=yes. This is symmetric with -k (disable GSSAPI)
and is useful for hosts with /home on Kerberised NFS; bz #1312
patch from Markus.Kuhn AT cl.cam.ac.uk; ok dtucker@ markus@
[ssh.c]
fix slave exit value when a control master goes away without passing the
full exit status by ensuring that the slave reads a full int. bz#1261

[scp.c]
make scp try to skip FIFOs rather than blocking when nothing is listening.
depends on the platform supporting sane O_NONBLOCK semantics for open
on FIFOs (apparently POSIX does not mandate this), which OpenBSD does.
bz #856; report by cjwatson AT debian.org; ok markus@
[ssh-add.1]
better document ssh-add's -d option (delete identies from agent), bz#1224
new text based on some provided by andrewmc-debian AT celt.dias.ie;
ok dtucker@
[ssh_config]
Add a "MACs" line after "Ciphers" with the default MAC algorithms,
to ease people who want to tweak both (eg. for performance reasons).

[kex.h mac.c mac.h monitor_wrap.c myproposal.h packet.c ssh.1]
[ssh_config.5 sshd.8 sshd_config.5]
Add a new MAC algorithm for data integrity, UMAC-64 (not default yet,
must specify umac-64@openssh.com). Provides about 20% end-to-end speedup
compared to hmac-md5. Represents a different approach to message
authentication to that of HMAC that may be beneficial if HMAC based on
one of its underlying hash algorithms is found to be vulnerable to a
new attack. http://www.ietf.org/rfc/rfc4418.txt
in conjunction with and OK djm@
[kex.c monitor_wrap.c packet.c mac.h kex.h mac.c]
Preserve MAC ctx between packets, saving 2xhash calls per-packet.
Yields around a 12-16% end-to-end speedup for arcfour256/hmac-md5
patch from markus@ tested dtucker@ and myself, ok markus@ and me (I'm
committing at his request)
