XXX I would appreciate if someone could test it under a real amd64
host with an up-to-date kernel, so I can reasonably assume that the
culprit is Virtual Box and not our amd64 port (my test machine being
off line I cannot do it myself). Results from other arches would be a
plus too.
I just updated one of my machines (running a bulldozer FX-8150) to
-current from an hour ago (with the most up-to-date rev of psl.h) and
ran atf-run on the libc/gen tests. The machine hung solid at this
point:
...
t_siginfo (28/32): 8 test cases
sigalarm: [1.006950s] Passed.
sigbus_adraln:
and I am no longer able to telnet into the box from elsewhere. I am
not physically at the machine, so I cannot tell if it has dropped into
ddb.
The machine did not drop into ddb, it simply rebooted. Unfortunately
it did not leave a core dump behind, so I don't have much to look at
just yet. When I get home later today, I will try to get more info.
BTW, this occurred while running the ATF test from a non-privileged
user, so if there's a bug lurking in these recent changes, it could
be
considered to be a security vulnerability - non-priv user should not
be able to crash the box...
