Taehee Yoo 32759da24e hsr: check protocol version in hsr_newlink() ... [ Upstream commit 4faab8c446def7667adf1f722456c2f4c304069c ] In the current hsr code, only 0 and 1 protocol versions are valid. But current hsr code doesn't check the version, which is received by userspace. Test commands: ip link add dummy0 type dummy ip link add dummy1 type dummy ip link add hsr0 type hsr slave1 dummy0 slave2 dummy1 version 4 In the test commands, version 4 is invalid. So, the command should be failed. After this patch, following error will occur. "Error: hsr: Only versions 0..1 are supported."
