Check for MIKDIR_P and use it instead of mkinstalldirs. Should fix "mkdir:
cannot create directory:... File exists" during "make install".
Patch from eb at emlix.com.
We don't support openssl-1.1.x yet (see multiple threads on the
openssh-unix-dev@ mailing list for the reason), but previously
./configure would accept it and the compilation would subsequently
fail. This makes ./configure display an explicit error message and
abort.

On some platforms (AIX, maybe others) allocating zero bytes of memory
via the various *alloc functions returns NULL, which is permitted
by the standards. Autoconf has some macros for detecting this (with
the exception of calloc for some reason) so use these and if necessary
activate shims for them. ok djm@
It's still on by default, but now it's possible to turn it off using
--without-hardening. This is useful since it's known to cause problems
with some -fsanitize options. ok dtucker@
Some CFLAGS/LDFLAGS may disrupt the configure script's operation,
in particular santization and fuzzer options that break assumptions
about memory and file descriptor dispositions.
This adds two flags to configure --with-cflags-after and
--with-ldflags-after that allow specifying additional compiler and
linker options that are added to the resultant Makefiles but not
used in the configure run itself.
E.g.
env CC=clang-3.9 ./configure \
--with-cflags-after=-fsantize=address \
--with-ldflags-after="-g -fsanitize=address"
FreeBSD's <sys/capability.h> was renamed to <sys/capsicum.h> in 2014 to
avoid future conflicts with POSIX capabilities (the last release that
didn't have it was 9.3) so switch to that. Patch from des at des.no.
Include replacement timespeccmp() for systems that lack it.
Support time_t struct stat->st_mtime in addition to
timespec stat->st_mtim, as well as unsorted fallback.
Should fix bz#2603 - "Build with ldns and without kerberos support
fails if ldns compiled with kerberos support" by including correct
cflags/libs

Having _XOPEN_SOURCE unconditionally causes problems on some platforms
and configurations, notably Solaris 64-bit binaries. It was there for
the benefit of Linux put the required bits in the *-*linux* section.
Patch from yvoinov at gmail.com.
NetBSD added an strnvis and unfortunately made it incompatible with the
existing one in OpenBSD and Linux's libbsd (the former having existed
for over ten years). Despite this incompatibility being reported during
development (see http://gnats.netbsd.org/44977) they still shipped it.
Even more unfortunately FreeBSD and later MacOS picked up this incompatible
implementation. Try to detect this mess, and assume the only safe option
if we're cross compiling.
OpenBSD 2.9 (2001): strnvis(char *dst, const char *src, size_t dlen, int flag);
NetBSD 6.0 (2012): strnvis(char *dst, size_t dlen, const char *src, int flag);

Where possible, use Solaris setpflags to disable process tracing on
ssh-agent and sftp-server. bz#2584, based on a patch from huieying.lee
at oracle.com, ok djm.
Replace by defining IPPORT_RESERVED to zero on Cygwin, which should have
the same effect without causing problems syncing patches with OpenBSD.
Resync the two affected functions with OpenBSD. ok djm, sanity checked
by Corinna.
sshd was failing with:
ssh_sandbox_child: sandbox_init: dlopen(/usr/lib/libsandbox.1.dylib, 261):cw
image not found [preauth]
caused by chroot before sandboxing. Avoid by explicitly linking libsandbox
to sshd. Spotted by Darren.
Not all systems with Solaris privs have priv_basicset so factor that
out and provide backward compatibility code. Similarly, not all have
PRIV_NET_ACCESS so wrap that in #ifdef. Based on code from
alex at cooperi.net and djm@ with help from carson at taltos.org and
wieland at purdue.edu.
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 changes configure.ac to look for '${host}-ar' as set by
AC_CANONICAL_HOST before looking for the unprefixed 'ar'.
Useful when cross-compiling when all your binutils are prefixed.
Patch from moben at exherbo org via astrand at lysator liu se and
bz#2352.
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.
[openbsd-compat/bsd-cygwin_util.h] On Cygwin, determine privilege
separation user at runtime, since it may need to be a domain account.
Patch from Corinna Vinschen.
different symbols for 'read' when various compiler flags are
in use, causing atomicio.c comparisons against it to break and
read/write operations to hang; ok dtucker
