Since commit a4a710c4 (pkt_sched: Change PSCHED_SHIFT from 10 to
6) it seems RED/GRED are broken.

red_calc_qavg_from_idle_time() computes a delay in us units, but this
delay is now 16 times bigger than real delay, so the final qavg result
smaller than expected.

Use standard kernel time services since there is no need to obfuscate
them.

A recent fix to the the NetLabel code caused build problem with
configurations that did not have IPv6 enabled; see below:

 netlabel_kapi.c: In function 'netlbl_cfg_unlbl_map_add':
 netlabel_kapi.c:165:4:
  error: implicit declaration of function 'netlbl_af6list_add'

This patch fixes this problem by making the IPv6 specific code conditional
on the IPv6 configuration flags as we done in the rest of NetLabel and the
network stack as a whole.  We have to move some variable declarations
around as a result so things may not be quite as pretty, but at least it
builds cleanly now.

Some additional IPv6 conditionals were added to the NetLabel code as well
for the sake of consistency.

The check from commit 30c2235c is incomplete and cannot prevent
cases like key_len = 0x80000000 (INT_MAX + 1).  In that case, the
left-hand side of the check (INT_MAX - key_len), which is unsigned,
becomes 0xffffffff (UINT_MAX) and bypasses the check.

However this shouldn't be a security issue.  The function is called
from the following two code paths:

 1) setsockopt()

 2) sctp_auth_asoc_set_secret()

In case (1), sca_keylength is never going to exceed 65535 since it's
bounded by a u16 from the user API.  As such, the key length will
never overflow.

In case (2), sca_keylength is computed based on the user key (1 short)
and 2 * key_vector (3 shorts) for a total of 7 * USHRT_MAX, which still
will not overflow.

In other words, this overflow check is not really necessary.  Just
make it more correct.

When a packet is supposed to sent be as an a-MPDU, mac80211 sets
IEEE80211_TX_CTL_AMPDU to let the driver know. On the other
hand, mac80211 configures the driver for aggregration with the
ampdu_action callback.
There is race between these two mechanisms since the following
scenario can occur when the BA agreement is torn down:

Tx softIRQ	 			drv configuration
==========				=================

check OPERATIONAL bit
Set the TX_CTL_AMPDU bit in the packet

					clear OPERATIONAL bit
					stop Tx AGG
Pass Tx packet to the driver.

In that case the driver would get a packet with TX_CTL_AMPDU set
although it has already been notified that the BA session has been
torn down.

To fix this, we need to synchronize all the Qdisc activity after we
cleared the OPERATIONAL bit. After that step, all the following
packets will be buffered until the driver reports it is ready to get
new packets for this RA / TID. This buffering allows not to run into
another race that would send packets with TX_CTL_AMPDU unset while
the driver hasn't been requested to tear down the BA session yet.

This race occurs in practice and iwlwifi complains with a WARN_ON
when it happens.

If addBA responses comes in just after addba_resp_timer has
expired mac80211 will still accept it and try to open the

in some cases even crash.

This patch fixes the race condition and makes sure that if
addba_resp_timer has expired addBA response is not longer
accepted and we do not try to open half-closed session.

already being stopped. So to fix it, check whether
stop is already being done and bail out if so.

As inetpeer is not yet namespace aware, this patch adds a shared

later if inetpeer becomes ns aware.

Cache information for one inerpeer is valid as long as its

When using l2tp over ipsec, the tunnel will hang when rekeying
occurs. Reason is that the transformer bundle attached to the dst entry
is now in STATE_DEAD and thus xfrm_output_one() drops all packets
(XfrmOutStateExpired increases).

Fix this by calling __sk_dst_check (which drops the stale dst
if xfrm dst->check callback finds that the bundle is no longer valid).

The pmtu informations on the inetpeer are visible for output and
input routes. On packet forwarding, we might propagate a learned
pmtu to the sender. As we update the pmtu informations of the
inetpeer on demand, the original sender of the forwarded packets
might never notice when the pmtu to that inetpeer increases.
So use the mtu of the outgoing device on packet forwarding instead
of the pmtu to the final destination.

Now that we enable multiqueue by default the ehea driver is using
quite a lot of memory for its buffer pools. With 4 queues we
consume 64MB in the jumbo packet ring, 16MB in the medium packet
ring and 16MB in the tiny packet ring.

We should only fill the jumbo ring once the MTU is increased but
for now halve it's size so it consumes 32MB. Also reduce the tiny
packet ring, with 4 queues we had 16k entries which is overkill.

When transmiting a fragmented skb, qlge fills a descriptor with the
fragment addresses, after DMA-mapping them. If there are more than eight
fragments, it will use the eighth descriptor as a pointer to an external
list. After mapping this external list, called OAL to a structure
containing more descriptors, it fills it with the extra fragments.

However, considering that systems with pages larger than 8KiB would have
less than 8 fragments, which was true before commit a715dea3, it
defined a macro for the OAL size as 0 in those cases.

Now, if a skb with more than 8 fragments (counting skb->data as one
fragment), this would start overwriting the list of addresses already
mapped and would make the driver fail to properly unmap the right
addresses on architectures with pages larger than 8KiB.

Besides that, the list of mappings was one size too small, since it must
have a mapping for the maxinum number of skb fragments plus one for
skb->data and another for the OAL. So, even on architectures with page
sizes 4KiB and 8KiB, a skb with the maximum number of fragments would
make the driver overwrite its counter for the number of mappings, which,
again, would make it fail to unmap the mapped DMA addresses.

When add sources to interface failure, need to roll back the sfcount[MODE]
to before state. We need to match it corresponding.
