Hi,
OpenSSH 7.8p1 is almost ready for release, so we would appreciate testing
on as many platforms and systems as possible. This is a bugfix release.
Snapshot releases for portable OpenSSH are available from
http://www.mindrot.org/openssh_snap/
The OpenBSD version is available in CVS HEAD:
http://www.openbsd.org/anoncvs.html
Portable OpenSSH is also available via git using the
instructions at http://www.openssh.com/portable.html#cvs
At https://anongit.mindrot.org/openssh.git/ or via a mirror at Github:
https://github.com/openssh/openssh-portable
Running the regression tests supplied with Portable OpenSSH does not
require installation and is a simply:
$ ./configure && make tests
Live testing on suitable non-production systems is also appreciated.
Please send reports of success or failure to
openssh-unix-dev@xxxxxxxxxxx. Security bugs should be reported
directly to openssh@xxxxxxxxxxx.
On Void Linux (kernel 4.14, glibc 2.26, gcc 7.3) I'm seeing a failure in
the test_kex unit test:
$ git rev-parse HEAD
e1b26ce504662a5d5b991091228984ccfd25f280
$ ./configure --with-pam --with-pie --with-sandbox=seccomp_filter

$ make tests
<...snip...>

regress/unittests/kex/test_kex.c:76 test #5 "kex"

server->kex->done = -649425904
1 = 1
Aborted
make[1]: *** [Makefile:225: unit] Error 134

Manually invoking regress/unittests/kex/test_kex, I see the value
printed for server->kex->done changing from one run to the next, which
made me suspect some sort of memory corruption or lack of
initialization, but running under valgrind doesn't show anything of the
sort:
