ipv6: Do not use routes from locally generated RAs 2011-10-24T23:13:15+00:00 Andreas Hofmeister andi@collax.com 2011-10-24T23:13:15+00:00 9f56220fad0d13f8b0ebe7592f41fdb49874d143 When hybrid mode is enabled (accept_ra == 2), the kernel also sees RAs generated locally. This is useful since it allows the kernel to auto-configure its own interface addresses. However, if 'accept_ra_defrtr' and/or 'accept_ra_rtr_pref' are set and the locally generated RAs announce the default route and/or other route information, the kernel happily inserts bogus routes with its own address as gateway. With this patch, adding routes from an RA will be skiped when the RAs source address matches any local address, just as if 'accept_ra_defrtr' and 'accept_ra_rtr_pref' were set to 0.
