Subject: [PATCH] ld.so on FC7 is mmap'ing shared libraries right in over guest memory.
Date: Thu, 09 Aug 2007 21:07:24 +1000 [thread overview]
Message-ID: <1186657645.17752.60.camel@localhost.localdomain> (raw)
From: Ronald G. Minnich <rminnich@gmail.com>
[ FC7 maps shared libraries very low, where the launcher maps guest's
physical memory. Quick fix is to link Launcher static, real fix is for
2.6.24. ]
-static is a simple fix. I expect this problem will be more common than we
like, as different distro's make different "improvements" to ld.so
