      IPV6: Fix default gateway criteria wrt. HIGH/LOW preference radv option · 22441cfa
      Pedro Ribeiro 提交于
      Problem observed:
                     In IPv6, in the presence of multiple routers candidates to
                     default gateway in one segment, each sending a different
                     value of preference, the Linux hosts connected to the
                     segment weren't selecting the right one in all the
                     combinations possible of LOW/MEDIUM/HIGH preference.
      
      This patch changes two files:
      include/linux/icmpv6.h
                     Get the "router_pref" bitfield in the right place
                     (as RFC4191 says), named the bit left with this fix as
                     "home_agent" (RFC3775 say that's his function)
      
      net/ipv6/ndisc.c
                     Corrects the binary logic behind the updating of the
                     router preference in the flags of the routing table
      
      Result:
                     With this two fixes applied, the default route used by
                     the system was to consistent with the rules mentioned
                     in RFC4191 in case of changes in the value of preference
                     in router advertisements
