Hello Alex Deucher,
The patch eed45b30cd14: "drm/radeon/kms: get HPD info for connectors"
from Dec 4, 2009, leads to the following warning:
"drivers/gpu/drm/radeon/radeon_atombios.c:950
radeon_get_atom_connector_info_from_supported_devices_table()
error: buffer overflow 'supported_devices->info.asConnInfo' 10 <= 15"
drivers/gpu/drm/radeon/radeon_atombios.c
943 if (frev > 1)
944 max_device = ATOM_MAX_SUPPORTED_DEVICE;
945 else
946 max_device = ATOM_MAX_SUPPORTED_DEVICE_INFO;
947
948 for (i = 0; i < max_device; i++) {
949 ATOM_CONNECTOR_INFO_I2C ci =
950 supported_devices->info.asConnInfo[i];
If max_device is set to ATOM_MAX_SUPPORTED_DEVICE then we read beyond
the end of the asConnInfo[] array and crash.
951
952 bios_connectors[i].valid = false;
953
regards,
dan carpenter
