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(). Patch from Peter Korsgaard <peter at korsgaard.com>

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@

2017-08-27Add missing includes for bsd-err.c.Darren Tucker
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@

2017-06-09Wrap stdint.h include in #ifdef.Darren Tucker

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@
2017-03-29Import fmt_scaled.c rev 1.15 from OpenBSD.Darren Tucker
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.
2016-12-13Add prototype for strcasestr in compat library.Darren Tucker
2016-12-13Add strcasestr to compat library.Darren Tucker
Fixes build on (at least) Solaris 10.
2016-10-28Move OPENSSL_NO_RIPEMD160 to compat.Darren Tucker
Move OPENSSL_NO_RIPEMD160 to compat and add ifdefs to mac.c around the ripemd160 MACs.
2016-10-26Use !=NULL instead of >0 for getdefaultproj.Darren Tucker
getdefaultproj() returns a pointer so test it for NULL inequality instead of >0. Fixes compiler warning and is more correct. Patch from David Binderman.
2016-10-19Import readpassphrase.c rev 1.26.Darren Tucker
Author: miller@openbsd.org: Avoid generate SIGTTOU when restoring the terminal mode. If we get SIGTTOU it means the process is not in the foreground process group which, in most cases, means that the shell has taken control of the tty. Requiring the user the fg the process in this case doesn't make sense and can result in both SIGTSTP and SIGTTOU being sent which can lead to the process being suspended again immediately after being brought into the foreground.
2016-10-19Import readpassphrase.c rev 1.25.Darren Tucker
Wrap <readpassphrase.h> so internal calls go direct and readpassphrase is weak. (DEF_WEAK is a no-op in portable.)
2016-10-15Move DEF_WEAK into defines.h.Darren Tucker
As well pull in more recent changes from OpenBSD these will start to arrive so put it where the definition is shared.
2016-10-13Import rev 1.24 from OpenBSD.Darren Tucker

2016-10-13Import rev 1.23 from OpenBSD. Fixes bz#2619.Darren Tucker
revision 1.23 date: 2010/05/14 13:30:34; author: millert; state: Exp; lines: +41 -39; Defer installing signal handlers until echo is disabled so that we get suspended normally when not the foreground process. Fix potential infinite loop when restoring terminal settings if process is in the background when restore occurs. OK miod@
2016-10-13If we don't have TCSASOFT, define it to zero.Darren Tucker
This makes it a no-op when we use it below, which allows us to re-sync those lines with the upstream and make future updates easier.
2016-09-29Remove portability support for mmapDamien Miller
We no longer need to wrap/replace mmap for portability now that pre-auth compression has been removed from OpenSSH.
2016-08-17Remove obsolete CVS $Id from source files.Darren Tucker
Since -portable switched to git the CVS $Id tags are no longer being updated and are becoming increasingly misleading. Remove them.
2016-08-16fix false positives when compiled with msanDamien Miller
Our explicit_bzero successfully confused clang -fsanitize-memory in to thinking that memset is never called to initialise memory. Ensure that it is called in a way that the compiler recognises.
2016-08-02Replace spaces with tabs.Darren Tucker
Mechanically replace spaces with tabs in compat files not synced with OpenBSD.
2016-08-02Strip trailing whitespace.Darren Tucker
Mechanically strip trailing whitespace on files not synced with OpenBSD (or in the case of bsd-snprint.c, rsync).

2016-07-21Search users for one with a valid salt.Darren Tucker
If the root account is locked (eg password "!!" or "*LK*") keep looking until we find a user with a valid salt to use for crypting passwords of invalid users. ok djm@
2016-07-15cast to avoid type warning in error messageDamien Miller
2016-07-15Move VA_COPY macro into compat header.Darren Tucker
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@
2016-07-15Determine appropriate salt for invalid users.Darren Tucker
When sshd is processing a non-PAM login for a non-existent user it uses the string from the fakepw structure as the salt for crypt(3)ing the password supplied by the client. That string has a Blowfish prefix, so on systems that don't understand that crypt will fail fast due to an invalid salt, and even on those that do it may have significantly different timing from the hash methods used for real accounts (eg sha512). This allows user enumeration by, eg, sending large password strings. This was noted by EddieEzra.Harari at verint.com (CVE-2016-6210). To mitigate, use the same hash algorithm that root uses for hashing passwords for users that do not exist on the system. ok djm@
2016-07-14Add compat code for missing wcwidth.Darren Tucker
If we don't have wcwidth force fallback implementations of nl_langinfo and mbtowc. Based on advice from Ingo Schwarze.
2016-07-13Move err.h replacements into compat lib.Darren Tucker
Move implementations of err.h replacement functions into their own file in the libopenbsd-compat so we can use them in kexfuzz.c too. ok djm@
2016-06-14Remove now-defunct .cvsignore files. ok djmDarren Tucker
2016-06-03Update vis.h and vis.c from OpenBSD.Darren Tucker
This will be needed for the upcoming utf8 changes.
