os_dump_core() uses abort() to terminate UML in case of an
fatal error.
glibc's abort() calls raise(SIGABRT) which makes use of tgkill().
tgkill() has no effect within UML's kernel threads because they
are not pthreads. As fallback abort() executes an invalid instruction
to terminate the process. T
When os_dump_core() raises SIGTERM to bring down all
UML processes this would also trigger the quite complex
do_uml_exitcalls() routine.
This is why UML crashed often while panicking.
Let's make os_dump_core() short and painless by killing all UML
processes with SIGHUP and calling the only sane ex
The UML kernel ignores SIGHUP anyway.
This handler is in vain.

UML_LIB_PATH is hardcoded to /usr/lib/uml/,
on 64bit systems UML_LIB_PATH needs to be /usr/lib64/uml/.

The ucast transport is similar to the mcast transport (and, in fact,
shares most of its code), only it uses UDP unicast to move packets.
Obviously this is only useful for point-to-point connections between
virtual ethernet devices.

User Mode Linux can also benefit from earlyprintk.
UML's earlyprintk writes kernel messages directly to stdout.
