[PATCH] die_if_kernel() can return (CVE-2006-0742)

2006-03-05T19:07:18+00:00

arch/ia64/kernel/unaligned.c erroneously marked die_if_kernel() with a "noreturn" attribute ... which is silly (it returns whenever the argument regs say that the fault happened in user mode, as one might expect given the "if_kernel" part of its name!).

[PATCH] i386: Move phys_proc_id/early intel workaround to correct function

2006-03-01T22:36:32+00:00

early_cpu_detect only runs on the BP, but this code needs to run on all CPUs. This will fix problems with the powernow-k8 driver on dual core systems and general misdetection of AMD dual core. Looks like a mismerge somewhere. Also add a warning comment. Signed-off-by: Andi Kleen Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman

[PATCH] ppc32: Put cache flush routines back into .relocate_code section

2006-03-01T22:36:31+00:00

In 2.6.14, we had the following definition of _GLOBAL() in include/asm-ppc/processor.h: #define _GLOBAL(n)\ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n;\ n: In 2.6.15, as part of the great powerpc merge, we moved this definition to include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as: #define _GLOBAL(n) \ .text; \ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n; \ n: Mostly, this is fine. However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

[PATCH] x86_64: Dont record local apic ids when they are disabled in MADT

2006-02-10T07:20:16+00:00

Some broken BIOS's had processors disabled, but same apic id as a valid processor. This causes acpi_processor_start() to think this disabled cpu is ok, and croak. So we dont record bad apicid's anymore. http://bugzilla.kernel.org/show_bug.cgi?id=5930 Signed-off-by: Ashok Raj Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds Signed-off-by: Chris Wright Signed-off-by: Greg Kroah-Hartman

[PATCH] x86_64: Let impossible CPUs point to reference per cpu data

2006-02-10T07:20:13+00:00

Don't mark the reference per cpu data init data (so it stays around after boot) and point all impossible CPUs to it. This way they reference some valid - although shared memory. Usually this is only initialization like INIT_LIST_HEADs and there won't be races because these CPUs never run. Still somewhat hackish.
