      "message": "[PATCH] vdso: randomize the i386 vDSO by moving it into a vma\n\nMove the i386 VDSO down into a vma and thus randomize it.\n\nBesides the security implications, this feature also helps debuggers, which\ncan COW a vma-backed VDSO just like a normal DSO and can thus do\nsingle-stepping and other debugging features.\n\nIt\u0027s good for hypervisors (Xen, VMWare) too, which typically live in the same\nhigh-mapped address space as the VDSO, hence whenever the VDSO is used, they\nget lots of guest pagefaults and have to fix such guest accesses up - which\nslows things down instead of speeding things up (the primary purpose of the\nVDSO).\n\nThere\u0027s a new CONFIG_COMPAT_VDSO (default\u003dy) option, which provides support\nfor older glibcs that still rely on a prelinked high-mapped VDSO.  Newer\ndistributions (using glibc 2.3.3 or later) can turn this option off.  Turning\nit off is also recommended for security reasons: attackers cannot use the\npredictable high-mapped VDSO page as syscall trampoline anymore.\n\nThere is a new vdso\u003d[0|1] boot option as well, and a runtime\n/proc/sys/vm/vdso_enabled sysctl switch, that allows the VDSO to be turned\non/off.\n\n(This version of the VDSO-randomization patch also has working ELF\ncoredumping, the previous patch crashed in the coredumping code.)\n\nThis code is a combined work of the exec-shield VDSO randomization\ncode and Gerd Hoffmann\u0027s hypervisor-centric VDSO patch. Rusty Russell\nstarted this patch and i completed it.\n\n[akpm@osdl.org: cleanups]\n[akpm@osdl.org: compile fix]\n[akpm@osdl.org: compile fix 2]\n[akpm@osdl.org: compile fix 3]\n[akpm@osdl.org: revernt MAXMEM change]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@infradead.org\u003e\nCc: Gerd Hoffmann \u003ckraxel@suse.de\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Andi Kleen \u003cak@muc.de\u003e\nCc: Jan Beulich \u003cjbeulich@novell.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
