Subject: Is CLONE_VM really needed in gdbserver?
Date: Tue, 26 Jan 2010 23:51:00 -0000	[thread overview]
Message-ID: <6dc9ffc81001261551j6221db6v88e96713d6dd9497@mail.gmail.com> (raw)

Hi,

There is a race condition between gdbserver and ld.so on Linux/x86-64:

http://www.sourceware.org/bugzilla/show_bug.cgi?id=11214

Is CLONE_VM really needed? In general, CLONE_VM is a very bad
idea if there is any symbol lookup in both parent and child processes.

Thanks.


H.J.
