ipv6: protocol for address routes

2008-08-23T12:16:46Z

This fixes a problem spotted with zebra, but not sure if it is necessary a kernel problem. With IPV6 when an address is added to an interface, Zebra creates a duplicate RIB entry, one as a connected route, and other as a kernel route. When an address is added to an interface the RTN_NEWADDR message causes Zebra to create a connected route. In IPV4 when an address is added to an interface a RTN_NEWROUTE message is set to user space with the protocol RTPROT_KERNEL. Zebra ignores these messages, because it already has the connected route. The problem is that route created in IPV6 has route protocol == RTPROT_BOOT. Was this a design decision or a bug? This fixes it. Same patch applies to both net-2.6 and stable.

netns: Add network namespace argument to rt6_fill_node() and ipv6_dev_get_saddr()

2008-08-14T22:33:21Z

ipv6_dev_get_saddr() blindly de-references dst_dev to get the network namespace, but some callers might pass NULL. Change callers to pass a namespace pointer instead. Signed-off-by: Brian Haley Signed-off-by: David S. Miller

net: convert BUG_TRAP to generic WARN_ON

2008-07-26T04:43:18Z

Removes legacy reinvent-the-wheel type thing. The generic machinery integrates much better to automated debugging aids such as kerneloops.org (and others), and is unambiguous due to better naming. Non-intuively BUG_TRAP() is actually equal to WARN_ON() rather than BUG_ON() though some might actually be promoted to BUG_ON() but I left that to future. I could make at least one BUILD_BUG_ON conversion. Signed-off-by: Ilpo Järvinen Signed-off-by: David S. Miller

ipv6: fix race between ipv6_del_addr and DAD timer

2008-07-08T22:13:31Z

Consider the following scenario: ipv6_del_addr(ifp) ipv6_ifa_notify(RTM_DELADDR, ifp) ip6_del_rt(ifp->rt) after returning from the ipv6_ifa_notify and enabling BH-s back, but *before* calling the addrconf_del_timer the ifp->timer fires and: addrconf_dad_timer(ifp) addrconf_dad_completed(ifp) ipv6_ifa_notify(RTM_NEWADDR, ifp) ip6_ins_rt(ifp->rt) then return back to the ipv6_del_addr and: in6_ifa_put(ifp) inet6_ifa_finish_destroy(ifp) dst_release(&ifp->rt->u.dst) After this we have an ifp->rt inserted into fib6 lists, but queued for gc, which in turn can result in oopses in the fib6_run_gc. Maybe some other nasty things, but we caught only the oops in gc so far. The solution is to disarm the ifp->timer before flushing the rt from it.
