Commit 468d09f8946d40228c56de26fe4874b2f98067ed masked the state
interrupt (bit 20 of the cause register). This results in Radstone's
PPC7D repeatedly re-entering the interrupt routine, locking up the

Make a new function sfq_q_enqueue() that operates directly on the

a later patch. A pleasant side-effect is reducing most of the
duplicate code in sfq_enqueue() and sfq_requeue().
Similarly, make a new function sfq_q_dequeue().
Factor code out of sfq_init() and sfq_destroy(), again so that the
new functions can be used by sfq_change() later.
Actually, as the diff itself shows, most of the sfq_q_init() code
comes from the original sfq_change(), but sfq_change() is only
called by sfq_init() right now. Thus, it is safe to

certainly is ok to send ICMPv6 errors to multicast addresses in general.

Hello,
I've a few questions about ICSK_ACK_PUSHED2.
PUSHED2 is only meant to force the ack out immediately when pingpong
is set to 1, but then if pingpong is 1 the delayed acks shouldn't be
deferred anyway. However I think the trouble is that there's a race
condition in reading pingpong,
Currently we have the call path:
macvlan_open - dev_unicast_add - __dev_set_rx_mode -
__dev_set_promiscuity - ASSERT_RTNL - mutex_trylock
When mutex debugging is on taking a mutex complains if we are not
allowed to sleep. At that point we have called netif_tx_lock_bh
so we are clearly

I need to be certain that something won't break. So this
patch deliberately disables all of the rtnletlink methods in everything
except the initial network namespace. After the methods have been
audited this extra check can be
After this patch none of the netlink callback support anything
except the initial network namespace but the rtnetlink infrastructure
now handles multiple network namespaces.

A multicast address should never be the target of a neighbor

After the previous prep work this just consists of removing checks
limiting the code to work in the initial network namespace, and
updating rtmsg_ifinfo so we can generate events for devices in
something other then the initial network namespace.
Referring to network other network devices like
This is done by making packet_sklist_lock and packet_sklist per

received packets to ensure they came from the proper network
