Add a ProxyJump ssh_config(5) option and corresponding -J ssh(1) command-line flag to allow simplified indirection through a SSH bastion or "jump host". These options construct a proxy command that connects to the specified jump host(s) (more than one may be specified) and uses port-forwarding to establish a connection to the next destination. This codifies the safest way of indirecting connections through SSH servers and makes it easy to use. ok markus@ Upstream-ID: fa899cb8b26d889da8f142eb9774c1ea36b04397

don't record duplicate LocalForward and RemoteForward entries; fixes failure with ExitOnForwardFailure+hostname canonicalisation where the same forwards are added on the second pass through the configuration file. bz#2562; ok dtucker@ Upstream-ID: 40a51d68b6300f1cc61deecdb7d4847b8b7b0de1

Another use for fcntl() and thus of the superfluous 3rd parameter is when sanitising standard fd's before calling daemon(). Use a tweaked version of the ssh(1) function in all three places found using fcntl() this way. ok jca@ beck@ Upstream-ID: f16811ffa19a1c5f4ef383c5f0fecb843c84e218
2016-03-09Add compat to monotime_double().Darren Tucker
Apply all of the portability changes in monotime() to monotime() double. Fixes build on at least older FreeBSD systems.

2015-12-09Don't set IPV6_V6ONLY on OpenBSDDamien Miller
It isn't necessary and runs afoul of pledge(2) restrictions.

Properly handle invalid %-format by calling fatal. ok deraadt, djm Upstream-ID: 5692bce7d9f6eaa9c488cb93d3b55e758bef1eac

Handle the split of tun(4) "link0" into tap(4) in ssh tun-forwarding. Adapted from portable (using separate devices for this is the normal case in most OS). ok djm@ Upstream-ID: 90facf4c59ce73d6741db1bc926e578ef465cd39

don't try to change tun device flags if they are already what we need; makes it possible to use tun/tap networking as non- root user if device permissions and interface flags are pre-established; based on patch by Ossi Herrala Upstream-ID: 89099ac4634cd477b066865acf54cb230780fd21
2015-04-29upstream commitderaadt@openbsd.org
rename xrealloc() to xreallocarray() since it follows that form. ok djm
2015-01-16upstream commitderaadt@openbsd.org
Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2014-10-27upstream commitlteo@openbsd.org
Remove unnecessary include: netinet/in_systm.h is not needed by these programs. NB. skipped for portable ok deraadt@ millert@
