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.
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@
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/getopt_long.c regress/modpipe.c] Remove getopt.c, add
portability code to getopt_long.c and switch over Makefile and the ugly
hack in modpipe.c. Fixes bz#1448.
openbsd-compat/bsd-setres_id.c openbsd-compat/bsd-setres_id.h
openbsd-compat/openbsd-compat.h] Move the fallback code for setting uids
and gids from uidswap.c to the compat library, which allows it to work with
the new setresuid calls in auth2-pubkey. with tim@, ok djm@

bz 1320: Add optional support for LDNS, a BSD licensed DNS resolver library
which supports DNSSEC. Patch from Simon Vallet (svallet at genoscope cns fr)
with some rework from myself and djm. ok djm.
openbsd-compat/openbsd-compat.h openbsd-compat/strptime.c] Add strptime to
the compat library which helps on platforms like old IRIX. Based on work
by djm, tested by Tom Christensen.
openbsd-compat/Makefile.in openbsd-compat/openbsd-compat.h
openbsd-compat/bsd-statvfs.{c,h}] Add a null implementation of statvfs and
fstatvfs and remove #defines around statvfs code. ok djm@
[openbsd-compat/fmt_scaled.c openbsd-compat/openbsd-compat.h]
Fix compilation on Linux, including pulling in fmt_scaled(3)
implementation from OpenBSD's libutil.
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@

contracts, enabled with --use-solaris-contracts. Patch from Chad
Mynhier, tweaked by dtucker@ and myself; ok dtucker@

[openbsd-compat/port-linux.h] Add support for SELinux, setting
the execution and TTY contexts. based on patch from Daniel Walsh,
bz #880; ok dtucker@

[openbsd-compat/openbsd-compat.h] Implement tun(4) forwarding
compatability support for Linux, diff from reyk@
openbsd-compat/bsd-snprintf.c openbsd-compat/openbsd-compat.h] Add an
asprintf() implementation, after syncing our {v,}snprintf() implementation
with some extra fixes from Samba's version. With help and debugging from
dtucker and tim; ok dtucker@
openbsd-compat/Makefile.in openbsd-compat/openbsd-compat.h
openbsd-compat/xcrypt.c] New files [openssh/openbsd-compat/port-uw.c

on UnixWare 7 from Dhiraj Gulati and Ahsan Rashid. Cleanup and testing
by tim@. Feedback and OK dtucker@
openbsd-compat/openbsd-compat.{c,h} openbsd-compat/openssl-compat.h]
Move compatibility code for supporting older OpenSSL versions to the
compat layer. Suggested by and "no objection" djm@
[openbsd-compat/openbsd-compat.h openbsd-compat/strtonum.c]
Add strtonum(3) from OpenBSD libc, new code needs it.
Unfortunately Linux forces us to do a bizarre dance with compiler
options to get LLONG_MIN/MAX; Spotted by and ok dtucker@
openbsd-compat/bsd-closefrom.c openbsd-compat/bsd-misc.c
openbsd-compat/bsd-misc.h openbsd-compat/openbsd-compat.h] Use smarter
closefrom() replacement from sudo; ok dtucker@
[sshpty.c]
for pty opening, only use the openpty() path. the other stuff only needs
to be in openssh-p; markus ok
- (djm) [openbsd-compat/bsd-openpty.c] Rework old sshpty.c code into an
openpty() replacement
openbsd-compat/xcrypt.h] Split off encryption into xcrypt() interface,
and isolate shadow password functions. Tested in Solaris, but should
not break other platforms too badly (except maybe HP =). Also brings
auth-passwd.c into full sync with OpenBSD tree.
openbsd-compat/Makefile.in] support compression on platforms that
have no/broken MAP_ANON. Moved code to openbsd-compat/xmmap.c
Based on patch from nalin@redhat.com of code extracted from Owl's package
