2015-06-06iscsi_ibft: filter null v4-mapped v6 addressesChris Leech1-15/+21
I've had reports of UEFI platforms failing iSCSI boot in various configurations, that ended up being caused by network initialization scripts getting tripped up by unexpected null addresses (0.0.0.0) being reported for gateways, dhcp servers, and dns servers. The tianocore EDK2 iSCSI driver generates an iBFT table that always uses IPv4-mapped IPv6 addresses for the NIC structure fields. This results in values that are "not present or not specified" being reported as ::ffff:0.0.0.0 rather than all zeros as specified. The iscsi_ibft module filters unspecified fields from the iBFT from sysfs, preventing userspace from using invalid values and making it easy to check for the presence of a value. This currently fails in regard to these mapped null addresses. In order to remain consistent with how the iBFT information is exposed, we should accommodate the behavior of the tianocore iSCSI driver as it's already in the wild in a large number of servers. Tested under qemu using an OVMF build of tianocore EDK2.

2015-06-06drm: fix writing to /sys/class/drm/*/statusRussell King1-1/+1
Writing to a file is supposed to return the number of bytes written. Returning zero unfortunately causes bash to constantly spin trying to write to the sysfs file, to such an extent that even ^c and ^z have no effect. The only way out of that is to kill the shell and log back in. This isn't nice behaviour. Fix it by returning the number of characters written to sysfs files.
