From: Alexander Aring <alex.aring@xxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit a8c2275493b866961f4429a741251c630c4fc6d7 upstream. The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with the ipv6_addr_src_scope function. Currently this can't be work, because ipv6_addr_scope returns a int with a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL is 0x02. So the condition is always false.
