2018-04-13Using "==" in shell tests is not portable.Darren Tucker
Patch from rsbecker at nexbridge.com.
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.
2018-03-25 Use libiaf on all sysv5 systemsTim Rice
2018-03-12Add AC_LANG_PROGRAM to AC_COMPILE_IFELSE.Darren Tucker
The recently added MIPS ABI tests need AC_LANG_PROGRAM to prevent warnings from autoconf. Pointed out by klausz at haus-gisela.de.
2018-03-08configure.ac: properly set seccomp_audit_arch for MIPS64Vicente Olivert Riera
Currently seccomp_audit_arch is set to AUDIT_ARCH_MIPS64 or AUDIT_ARCH_MIPSEL64 (depending on the endinness) when openssh is built for MIPS64. However, that's only valid for n64 ABI. The right macros for n32 ABI defined in seccomp.h are AUDIT_ARCH_MIPS64N32 and AUDIT_ARCH_MIPSEL64N32, for big and little endian respectively. Because of that an sshd built for MIPS64 n32 rejects connection attempts and the output of strace reveals that the problem is related to seccomp audit: [pid 194] prctl(PR_SET_SECCOMP, SECCOMP_MODE_FILTER, {len=57, filter=0x555d5da0}) = 0 [pid 194] write(7, "\0\0\0]\0\0\0\5\0\0\0Ulist_hostkey_types: "..., 97) = ? [pid 193] <... poll resumed> ) = 2 ([{fd=5, revents=POLLIN|POLLHUP}, {fd=6, revents=POLLHUP}]) [pid 194] +++ killed by SIGSYS +++ This patch fixes that problem by setting the right value to seccomp_audit_arch taking into account the MIPS64 ABI.

2018-03-05Disable UTMPX on SunOS4.Darren Tucker
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.
2018-02-27Check dlopen has RTLD_NOW before enabling pkcs11.Darren Tucker
2018-02-27Check for attributes on prototype args.Darren Tucker
Some compilers (gcc 2.9.53, 3.0 and probably others, see gcc bug #3481) do not accept __attribute__ on function pointer prototype args. Check for this and hide them if they're not accepted.
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.
2018-02-26XMSS-related files get includes.hDamien Miller
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.
2018-02-23Check for ifaddrs.h for BindInterface.Darren Tucker
BindInterface required getifaddr and friends so disable if not available (eg Solaris 10). We should be able to add support for some systems with a bit more work but this gets the building again.
2018-02-22Add headers for sys/audit.h.Darren Tucker
On some older platforms (at least sunos4, probably others) sys/audit.h requires some other headers. Patch from klausz at haus-gisela.de.
2018-02-18Remove now-unused check for getrusage.Darren Tucker
getrusage was used in ssh-rand-helper but that's now long gone. Patch from klauszh at haus-gisela.de.
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.
2018-02-13Retpoline linker flag only needed for linking.Darren Tucker
2018-02-13Default PidFile is sshd.pid not ssh.pid.Darren Tucker
2018-02-11Include headers for linux/if.h.Darren Tucker
Prevents configure-time "present but cannot be compiled" warning.
2018-02-11Fix test for -z,retpolineplt linker flag.Darren Tucker
2018-02-11Add checks for Spectre v2 mitigation (retpoline)Darren Tucker
This adds checks for gcc and clang flags for mitigations for Spectre variant 2, ie "retpoline". It'll automatically enabled if the compiler supports it as part of toolchain hardening flag. ok djm@
2018-02-07Remove obsolete "Smartcard support" messageDarren Tucker
The configure checks that populated $SCARD_MSG were removed in commits 7ea845e4 and d8f60022 when the smartcard support was replaced with PKCS#11.
2017-12-11Add autogenerated dependency info to Makefile.Darren Tucker
Adds a .depend file containing dependency information generated by makedepend, which is appended to the generated Makefile by configure. You can regen the file with "make -f Makefile.in depend" if necessary, but we'll be looking at some way to automatically keep this up to date. "no objection" djm@
2017-12-11Fix pasto in ldns handling.Darren Tucker
When ldns-config is not found, configure would check the wrong variable. ok djm@
2017-12-09Remove now-used check for perl.Darren Tucker
2017-12-01Replace mkinstalldirs with mkdir -p.Darren Tucker
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.
2017-11-03Check for linux/if.h when enabling rdomain.Darren Tucker
musl libc doesn't seem to have linux/if.h, so check for its presence before enabling rdomain support on Linux.
2017-11-03Add headers for sys/sysctl.h and net/route.hDarren Tucker
On at least older OpenBSDs, sys/sysctl.h and net/route.h require sys/types and, in the case of sys/sysctl.h, sys/param.h for MAXLOGNAME.
2017-10-25autoconf glue to enable Linux VRFDamien Miller
2017-10-25check for net/route.h and sys/sysctl.hDamien Miller
2017-09-28don't fatal ./configure for LibreSSLDamien Miller
2017-09-28abort in configure when only openssl-1.1.x foundDamien Miller
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. ok dtucker@
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@
2017-09-25Add minimal strsignal for platforms without it.Darren Tucker
2017-09-19add freezero(3) replacementDamien Miller
ok dtucker@
2017-09-19move FORTIFY_SOURCE into hardening options groupDamien Miller
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@
2017-09-08Give configure ability to set CFLAGS/LDFLAGS laterDamien Miller
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"
2017-08-28Switch Capsicum header to sys/capsicum.h.Darren Tucker
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.

UnixWare needs BROKEN_TCGETATTR_ICANON like Solaris Analysis by Robbie Zhang
2017-06-10portability for sftp globbed ls sort by mtimeDamien Miller
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.
2017-06-01add recallocarray replacement and dependencyDamien Miller
recallocarray() needs getpagesize() so add a tiny replacement for that.
