f88a4a9b65 bonding/vlan: Fix mangled NAs on slaves without VLAN tag insertion
bond_na_send() attempts to insert a VLAN tag in between building and
sending packets of the respective formats.  If the slave does not
implement hardware VLAN tag insertion then vlan_put_tag() will mangle
the network-layer header because the Ethernet header is not present at
this point (unlike in bond_arp_send()).

Fix this by adding the tag out-of-line and relying on
dev_hard_start_xmit() to insert it inline if necessary.

bond_change_active_slave() may be called when a slave is added, even
if the bond has not been brought up yet.  It may then attempt to send
packets, and further it may use mcast_work which is uninitialised
before the bond is brought up.  Add the necessary checks for
netif_running(bond->dev).

8387451e55 bonding/vlan: Remove redundant VLAN tag insertion logic
A bond may have a mixture of slave devices with and without hardware
VLAN tag insertion capability.  Therefore it always claims this
capability and performs software VLAN tag insertion if the slave does
not.

Since commit 7b9c609037, this has
also been done by dev_hard_start_xmit().  The result is that VLAN-
tagged skbs are now double-tagged when transmitted through slave
devices without hardware VLAN tag insertion!

Remove the now-redundant logic from bond_dev_queue_xmit().

d3052b557a ipv6: delete expired route in ip6_pmtu_deliver
The first big packets sent to a "low-MTU" client correctly
triggers the creation of a temporary route containing the reduced MTU.

But after the temporary route has expired, new ICMP6 "packet too big"
will be sent, rt6_pmtu_discovery will find the previous EXPIRED route
check that its mtu isn't bigger then in icmp packet and do nothing
before the temporary route will not deleted by gc.

I make the simple experiment:
while :; do
    time ( dd if=/dev/zero bs=10K count=1 | ssh hostname dd of=/dev/null ) || break;
done

The "time" reports real 0m0.197s if a temporary route isn't expired, but
it reports real 0m52.837s (!!!!) immediately after a temporare route has
expired.

d33e455337 net: Abstract default MTU metric calculation behind an accessor.
Like RTAX_ADVMSS, make the default calculation go through a dst_ops
method rather than caching the computation in the routing cache
entries.

Now dst metrics are pretty much left as-is when new entries are
created, thus optimizing metric sharing becomes a real possibility.

0dbaee3b37 net: Abstract default ADVMSS behind an accessor.
Make all RTAX_ADVMSS metric accesses go through a new helper function,
dst_metric_advmss().

Leave the actual default metric as "zero" in the real metric slot,
and compute the actual default value dynamically via a new dst_ops
AF specific callback.

For stacked IPSEC routes, we use the advmss of the path which
preserves existing behavior.

Unlike ipv4/ipv6, DecNET ties the advmss to the mtu and thus updates
advmss on pmtu updates.  This inconsistency in advmss handling
results in more raw metric accesses than I wish we ended up with.

8808f64171 mac80211: avoid calling ieee80211_work_work unconditionally
On suspend, there might be usb wireless drivers which wrongly trigger
the warning in ieee80211_work_work. If an usb driver doesn't have a
suspend hook, the usb stack will disconnect the device. On disconnect,
a mac80211 driver calls ieee80211_unregister_hw, which calls dev_close,
which calls ieee80211_stop, and in the end calls ieee80211_work_purge->
ieee80211_work_work.

The problem is that this call to ieee80211_work_purge comes after
mac80211 is suspended, triggering the warning even when we don't have
work queued in work_list (the expected case when already suspended),
because it always calls ieee80211_work_work.

So, just call ieee80211_work_work in ieee80211_work_purge if we really
have to abort work. This addresses the warning reported at
https://bugzilla.kernel.org/show_bug.cgi?id=24402
