I just compiled and ran the tests for openssl-snap-20150531 on Linux (Ubuntu 14.04.2 LTS) and MacOS (10.10.3).

On Linux, the code compiled cleanly. However, during “make tests” I got the following error a number of times:

WARNING: /usr/local/etc/moduli does not exist, using fixed modulus

Later in the test sequence I got the error:

run test ...
Missing privilege separation directory: /var/empty
FATAL: sshd_proxy broken
make[1]: *** [t-exec] Error 1
make[1]: Leaving directory `/tmp/openssh/regress'
make: *** [tests] Error 2
make tests  153.92s user 4.68s system 98% cpu 2:41.52 total

I was not running as root at the time, as I wasn’t intending to install this version. It looks like it assumes that /var/empty will already exist, though, which it doesn’t on my system. The currently installed sshd does have UsePrivilegeSeparation enabled, and it looks like the sshd user is set up with have /var/run/sshd as its home directory on this system, but the test script didn’t pick that up.

On MacOS, the code compiled, but there were a large number of warnings about constructs that were deprecated back in OS X 10.7. The output is quite large, but I’d be happy to provide it to anyone who wants it. Here’s an example of the first warning:

Other than these warnings, the code did compile on MacOS and successfully passed all the tests.

I can also confirm that this version fixes bz#2366, as noted in the change log.
