Bug#604453: linux-2.6: xen domU hangs with systemtap kernel.function("*@*/*.c")
Package: linux-2.6
Version: 2.6.32-27
Severity: minor
[ Note that I have applied a patch from #602273 so this is not a
completely unmodified linux-2.6 package.]
Steps to reproduce:
1) cat > mmap-trace.stp <<EOF
global trace
function trace(entry_p) {
if(tid() in trace)
printf("%s%s%s\n",
thread_indent(entry_p),
(entry_p>0?"->":"<-"),
probefunc())
}
probe syscall.execve {
# printf("%s\n", filename);
if (filename != "./mmap") next
trace[tid()] = 1
trace(1)
}
#probe syscall.execve.return {
# trace(-1)
# delete trace[tid()]
#}
#probe kernel.function("*@mm/*.c").call { trace(1) }
#probe kernel.function("*@mm/*.c").return { trace(-1) }
probe kernel.function("*@*/*.c").call { trace(1) }
probe kernel.function("*@*/*.c").return { trace(-1) }
probe begin {
printf("begin\n");
}
EOF
2) sudo stap ./mmap-trace.stp
Expected results:
2) The system does not crash
Actual results:
2) The system hangs and does not respond to ping.
