Basically, the loader finds a simple safe way to reboot that's worked
since the 286, and VMWare doesn't like it. It's called a triple fault.
FreeBSD and Linux even use it to reboot as a fail safe. Read
sys/i386/i386/vm_machdep.c and cpu_reset_real to see how FreeBSD handles
it. VMWare at le
The accept4() function, compared to accept(), allows setting the new
file descriptor atomically close-on-exec and explicitly controlling the
non-blocking status on the new socket. (Note that the latter point means
that accept() is not equivalent to any form of accept4().)

Certainly. Here is some of the debugging messages that I added to my

When running FreeBSD under VMware Workstation (I'm using 9.0.1, but this
issue has existed for many years now, I remember it occurring on
Workstation 6.x), the following is reproducible:
1. Power on + boot FreeBSD VM
2. At loader menu, press
roundhay# sysctl -a | grep jailed

Oh, of course, I mean, what do you have in td->td_ucred?
[Sreenivas] not sure, I referred to socreate() usage in the kernel source and
used it.
One more observation. Interface "cxgbe1" has a IPv6 interface and an IPv4
interface, print in
roundhay# sysctl -a | grep jailed
