2018-03-30Disable native strndup and strnlen on AIX.Darren Tucker
On at least some revisions of AIX, strndup returns unterminated strings under some conditions, apparently because strnlen returns incorrect values in those cases. Disable both on AIX and use the replacements from openbsd-compat. Fixes problem with ECDSA keys there, ok djm.
2018-03-26Include ssh_api.h for struct ssh.Darren Tucker
struct ssh is needed by implementations of sys_auth_passwd() that were converted in commit bba02a50. Needed to fix build on AIX, I assume for the other platforms too (although it should be harmless if not needed).
2018-03-26Remove UNICOS code missed during removal.Darren Tucker
Fixes compile error on AIX.
2018-03-25 modified: auth-sia.cTim Rice
modified: openbsd-compat/port-aix.c modified: openbsd-compat/port-uw.c propogate changes to auth-passwd.c in commit 7c856857607112a3dfe6414696bf4c7ab7fb0cb3 to other providers of sys_auth_passwd()
2018-03-05Check for and work around buggy fflush(NULL).Darren Tucker
Some really old platforms (eg SunOS4) segfault on fflush(NULL) so check for and work around. With klausz at haus-gisela.de.
2018-03-03Add strndup for platforms that need it.Darren Tucker
Some platforms don't have strndup, which includes Solaris 10, NetBSD 3 and FreeBSD 6.
2018-03-03Flatten and alphabetize object file lists.Darren Tucker
This will make maintenance and changes easier. "no objection" tim@
2018-02-27Check if HAVE_DECL_BZERO correctly.Darren Tucker
2018-02-26typo: missing ;Darren Tucker
2018-02-26Hook up flock() compat code.Darren Tucker
Also a couple of minor changes: fail if we can't lock instead of silently succeeding, and apply a couple of minor style fixes.
2018-02-26Import flock() compat from NetBSD.Darren Tucker
From NetBSD's src/trunk/tools/compat/flock.c, no OpenSSH changes yet.
2018-02-26avoid inclusion of deprecated selinux/flask.hDamien Miller
Use string_to_security_class() instead.
2018-02-26Invert sense of getpgrp test.Darren Tucker
AC_FUNC_GETPGRP tests if getpgrp(0) works, which it does if it's not declared. Instead, test if the zero-arg version we want to use works.
2018-02-26Add no-op getsid implmentation.Darren Tucker
2018-02-26bsd-statvfs: include sys/vfs.h, check for f_flags.Darren Tucker
2018-02-26Handle calloc(0,x) where different from malloc.Darren Tucker
Configure assumes that if malloc(0) returns null then calloc(0,n) also does. On some old platforms (SunOS4) malloc behaves as expected (as determined by AC_FUNC_MALLOC) but calloc doesn't. Test for this at configure time and activate the replacement function if found, plus handle this case in rpl_calloc.
2018-02-26Add prototype for readv if needed.Darren Tucker
2018-02-26Check for raise and supply if needed.Darren Tucker
2018-02-26Check for bzero and supply if needed.Darren Tucker
Since explicit_bzero uses it via an indirect it needs to be a function not just a macro.
2018-02-16freezero should check for NULL.Darren Tucker
2018-02-15Remove remaining now-obsolete cvs $Ids.Darren Tucker
2018-02-15Remove UNICOS support.Darren Tucker
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.
2018-02-11Move signal compat code into bsd-signal.{c,h}Darren Tucker
2017-11-24Include string.h for explicit_bzero.Darren Tucker
2017-10-31Include includes.h for HAVE_GETPAGESIZE.Darren Tucker
The configure script checks for getpagesize() and sets HAVE_GETPAGESIZE in config.h, but bsd-getpagesize.c forgot to include includes.h (which indirectly includes config.h) so the checks always fails, causing linker issues when linking statically on systems with getpagesize().

2017-10-23upstream commitdjm@openbsd.org
Expose devices allocated for tun/tap forwarding. At the client, the device may be obtained from a new %T expansion for LocalCommand. At the server, the allocated devices will be listed in a SSH_TUNNEL variable exposed to the environment of any user sessions started after the tunnel forwarding was established. ok markus Upstream-ID: e61e53f8ae80566e9ddc0d67a5df5bdf2f3c9f9e
2017-09-27Check for and handle calloc(p, 0) = NULL.Darren Tucker
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@

Patch from cjwatson at debian.org via bz#2767.
2017-07-28fix problems in tunnel forwarding portability codeDamien Miller
This fixes a few problems in the tun forwarding code, mostly to do with host/network byte order confusion. Based on a report and patch by stepe AT centaurus.uberspace.de; bz#2735; ok dtucker@

2017-06-01add recallocarray replacement and dependencyDamien Miller
recallocarray() needs getpagesize() so add a tiny replacement for that.
2017-03-29Import fmt_scaled.c rev 1.16 from OpenBSD.Darren Tucker
Fix overly-conservative overflow checks on mulitplications and add checks on additions. This allows scan_scaled to work up to +/-LLONG_MAX (LLONG_MIN will still be flagged as a range error). ok millert@

Collapse underflow and overflow checks into a single block. ok djm@ millert@

2016-12-13Remove commented-out includes.Darren Tucker
These commented-out includes have "Still needed?" comments. Since they've been commented out for ~13 years I assert that they're not.
