ipv6: fix race between ipv6_del_addr and DAD timer

2008-07-08T22:13:31+00:00

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.

ipv6 route: Convert rt6_device_match() to use RT6_LOOKUP_F_xxx flags.

2008-06-28T03:14:54+00:00

The commit 77d16f450ae0452d7d4b009f78debb1294fb435c ("[IPV6] ROUTE:
Unify RT6_F_xxx and RT6_SELECT_F_xxx flags") intended to pass various
routing lookup hints around RT6_LOOKUP_F_xxx flags, but conversion was
missing for rt6_device_match().

inet fragments: fix race between inet_frag_find and inet_frag_secret_rebuild

2008-06-28T03:06:08+00:00

The problem is that while we work w/o the inet_frags.lock even
read-locked the secret rebuild timer may occur (on another CPU, since
BHs are still disabled in the inet_frag_find) and change the rnd seed
for ipv4/6 fragments.

It was caused by my patch fd9e63544cac30a34c951f0ec958038f0529e244
([INET]: Omit double hash calculations in xxx_frag_intern) late 
in the 2.6.24 kernel, so this should probably be queued to -stable.

tcp: /proc/net/tcp rto,ato values not scaled properly (v2)

2008-06-28T03:00:19+00:00

I found another case where we are sending information to userspace
in the wrong HZ scale.  This should have been fixed back in 2.5 :-(

This means an ABI change but as it stands there is no way for an application
like ss to get the right value.

netfilter: ip6table_mangle: don't reroute in LOCAL_IN

2008-06-24T20:30:45+00:00

Rerouting should only happen in LOCAL_OUT, in INPUT its useless
since the packet has already chosen its final destination.

Noticed by Alexey Dobriyan .

ipv6: Remove options header when setsockopt's optlen is 0

2008-06-19T23:29:39+00:00

Remove the sticky Hop-by-Hop options header by calling setsockopt()
for IPV6_HOPOPTS with a zero option length, per RFC3542.

Routing header and Destination options header does the same as
Hop-by-Hop options header.

ipv6 sit: Avoid extra need for compat layer in PRL management.

2008-06-16T23:48:20+00:00

We've introduced extra need of compat layer for ip_tunnel_prl{}
for PRL (Potential Router List) management.  Though compat_ioctl
is still missing in ipv4/ipv6, let's make the interface more
straight-forward and eliminate extra need for nasty compat layer
anyway since the interface is new for 2.6.26.
