2.6.23-stable review patch. If anyone has any objections, please let us know. ------------------ From: William Lee Irwin III The ->cap fields of struct acpi_video_device and struct acpi_video_bus are 1B each, not 4B. The oversized memset()'s corrupted the subsequent list_head fields. This resulted in silent corruption without CONFIG_DEBUG_LIST and BUG's with it. This patch uses sizeof() to pass the proper bounds to the memset() calls and thereby correct the bugs. upstream commit 98934def70b48dac74fac3738b78ab2d1a28edda Signed-off-by: William Irwin Acked-by: Mikael Pettersson Signed-off-by: Len Brown Signed-off-by: Greg Kroah-Hartman --- drivers/acpi/video.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -573,7 +573,7 @@ static void acpi_video_device_find_cap(s struct acpi_video_device_brightness *br = NULL; - memset(&device->cap, 0, 4); + memset(&device->cap, 0, sizeof(device->cap)); if (ACPI_SUCCESS(acpi_get_handle(device->dev->handle, "_ADR", &h_dummy1))) { device->cap._ADR = 1; @@ -693,7 +693,7 @@ static void acpi_video_bus_find_cap(stru { acpi_handle h_dummy1; - memset(&video->cap, 0, 4); + memset(&video->cap, 0, sizeof(video->cap)); if (ACPI_SUCCESS(acpi_get_handle(video->device->handle, "_DOS", &h_dummy1))) { video->cap._DOS = 1; } -- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
