The main change is that Niels Provos kindly agreed to rescind the
BSD license advertising clause, shifting them to the 3-term BSD
license.
This was the last thing in OpenSSH that used the advertising clause.
FreeBSD has login_getpwclass() that does some special magic for
UID=0. Prefer this to login_getclass() as its easier to emulate
the former with the latter.
Based on FreeBSD PR 37416 via Ed Maste; ok dtucker@
We needed a mkdtemp() that accepted template paths that did not
end in XXXXXX a long time ago for KRB4, but that code is long
deprecated. We no longer need to replace mkdtemp() for strictly
following POSIX. ok dtucker@
If the system (or one of the dependencies) implements memmem but does
not define the header, we would not declare it either resulting in
compiler warnings. Check for declaration explicitly. bz#3102.
We shipped a BSD implementation of realpath() because sftp-server
depended on its behaviour.
OpenBSD is now moving to a more strictly POSIX-compliant realpath(2),
so sftp-server now unconditionally requires its own BSD-style realpath
implementation. As such, there is no need to carry another independant
implementation in openbsd-compat.

Add getline for the benefit of platforms that don't have it. Sourced
from NetBSD (OpenBSD's implementation is a little too chummy with the
internals of FILE).
The code required to support it is quite invasive to the mainline
code that is synced with upstream and is an ongoing maintenance burden.
Both the hardware and software are literal museum pieces these days and
we could not find anyone still running OpenSSH on one.
Some AIX compilers unconditionally undefine va_copy but don't set it back
to an internal function, causing link errors. In some compat code we
already use VA_COPY instead so move the two existing instances into the
shared header and use for sshbuf-getput-basic.c too. Should fix building
with at lease some versions of AIX's compiler. bz#2589, ok djm@
Move glob.h from includes.h to the only caller (sftp) and override the
names for the symbols. This prevents name collisions with the system glob
in the case where something other than ssh uses it (eg kerberos). With
jjelen at redhat.com, ok djm@
On some platforms the native realpath doesn't work with non-existent
files (this is actually specified in some versions of POSIX), however
the sftp spec says its realpath with "canonicalize any given path name".
On those platforms, use realpath from the compat library.
In addition, when compiling with -DFORTIFY_SOURCE, glibc redefines
the realpath symbol to the checked version, so redefine ours to
something else so we pick up the compat version we want.
bz#2428, ok djm@
This might help with the reported problem cross compiling for Android
("error: expected identifier or '(' before numeric constant") but
shouldn't hurt in any case.
Disables and removes dependency on OpenSSL. Many features don't
work and the set of crypto options is greatly restricted. This
will only work on system with native arc4random or /dev/urandom.
Considered highly experimental for now.
