From 7a5bb9964512c5313af19310c6a3002ec54f7336 Mon Sep 17 00:00:00 2001 From: Lin Ming Date: Thu, 10 Apr 2008 19:06:43 +0400 Subject: ACPICA: Fix to handle NULL package elements correctly Fixed problem where NULL package elements were not returned to the AcpiEvaluateObject interface correctly. Instead of returning a NULL ACPI_OBJECT package element, the element was simply ignored, potentially causing a buffer overflow and/or confusing the caller who expected a fixed number of elements. http://bugzilla.kernel.org/show_bug.cgi?id=10132 Signed-off-by: Lin Ming Signed-off-by: Bob Moore Signed-off-by: Alexey Starikovskiy Signed-off-by: Len Brown --- drivers/acpi/utilities/utobject.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) (limited to 'drivers/acpi') diff --git a/drivers/acpi/utilities/utobject.c b/drivers/acpi/utilities/utobject.c index 1eccd3db876f..cdb8ff5b92d1 100644 --- a/drivers/acpi/utilities/utobject.c +++ b/drivers/acpi/utilities/utobject.c @@ -470,9 +470,8 @@ acpi_ut_get_simple_object_size(union acpi_operand_object *internal_object, case ACPI_TYPE_PROCESSOR: case ACPI_TYPE_POWER: - /* - * No extra data for these types - */ + /* No extra data for these types */ + break; case ACPI_TYPE_LOCAL_REFERENCE: -- cgit v1.2.3
