Subject: [Bug runtime/6964] process probes cause kernel crash on f9
Date: Tue, 21 Oct 2008 03:10:00 -0000 [thread overview]
Message-ID: <20081021030936.21630.qmail@sourceware.org> (raw)

------- Additional Comments From wenji dot huang at oracle dot com 2008-10-21 03:09 -------
Did some tests to narrow the scope.
It works fine for:
stap -vve 'probe kernel.function("sys_open"){}' -c ls
stap -vve 'probe process("./test").syscall {}' -c ls
only got crashed when
stap -vve 'probe process.syscall {}' -c ls
I guess the reason is the spawn process by stap is being hitted. Some signals
are delayed/messed so that BUG_ON in utrace_get_signal is triggered.
