ppp: fix BUG on non-linear SKB (multilink receive)
PPP does not correctly call pskb_may_pull() on all necessary receive paths
before reading the PPP protocol, thus causing PPP to report seemingly
random 'unsupported protocols' and eventually trigger BUG_ON(skb->len <
skb->data_len) in skb_pull_rcsum() when receiving multilink protocol in
non-linear skbs.
ppp_receive_nonmp_frame() does not call pskb_may_pull() before reading the
protocol number. For the non-mp receive path this is not a problem, as
this check is done in ppp_receive_frame(). For the mp receive path,
ppp_mp_reconstruct() usually copies the data into a new linear skb.
However, in the case where the frame is made up of a single mp fragment,
the mp header is pulled and the existing skb used. This skb was then
passed to ppp_receive_nonmp_frame() without checking if the encapsulated
protocol header could safely be read.

bonding: fix 802.3ad standards compliance error
The language of 802.3ad 43.4.9 requires the "recordPDU" function
to, in part, compare the Partner parameter values in a received LACPDU
to the stored Actor values. If those match, then the Partner's
synchronization state is set to true.
The current 802.3ad implementation is performing these steps out
of order; first, the synchronization check is done, then the paramters are
checked to see if they match (the synch check being done against a match
check of a prior LACPDU). This causes delays in establishing aggregators
in some circumstances.
This patch modifies the 802.3ad code to call __choose_matched,
the function that does the "match" comparisions, as the first step of
__record_pdu, instead of immediately afterwards. This new behavior is
in compliance with the language of the standard.
Some additional commentary relating to code vs. standard is also
added.

the logic of the fix and verified the patch.

Bluetooth: Fix regression with L2CAP configuration in Basic Mode
Basic Mode is the default mode of operation of a L2CAP entity. In

Indeed. But we dump at most one skb (<= 8192 bytes ?), so rcu_read_lock

Receive buffer size is used to configure hardware incoming packet filter.
For jumbo frames:
Receive buffer size = Max frame size = MTU + 14 (ethernet header) + 4
(vlan header) + 4 (ethernet checksum) = MTU + 22
Bug:
driver for all MTU up to 1536 use receive buffer size 1536
As you can see from formula, this mean all IP packets > 1536 - 22

host_good> ping host_r8169

different between IPv4 and IPv6. IPv4 case ended up working because the

a valid route was returned for first call, but we could not find a valid

Revert "libipw: initiate cfg80211 API conversion"
This reverts commit
b8ecd988b1670035a05035c553c08331214d6603.
Due to poor API call balancing by me, this commit not only broke ipw2200
if it can't find it's firmware, it broke ipw2100 basically anytime you
removed the module. At this point in the cycle, let's just put it back
to a sane state and try again next time...

vlan/macvlan: propagate transmission state to upper layers
Both vlan and macvlan devices usually don't use a qdisc and immediately
queue packets to the underlying device. Propagate transmission state of
the underlying device to the upper layers so they can react on congestion
and/or inform the sending process.

net: allow to propagate errors through ->ndo_hard_start_xmit()
Currently the ->ndo_hard_start_xmit() callbacks are only permitted to return
one of the NETDEV_TX codes. This prevents any kind of error propagation for
virtual devices, like queue congestion of the underlying device in case of
layered devices, or unreachability in case of tunnels.
This patches changes the NET_XMIT codes to avoid clashes with the NETDEV_TX
codes and changes the two callers of dev_hard_start_xmit() to expect either
errno codes, NET_XMIT codes or NETDEV_TX codes as return value.
In case of qdisc_restart(), all non NETDEV_TX codes are mapped to NETDEV_TX_OK
since no error propagation is possible when using qdiscs. In case of
dev_queue_xmit(), the error is propagated upwards.

tcp: provide more information on the tcp receive_queue bugs
The addition of rcv_nxt allows to discern whether the skb
was out of place or tp->copied. Also catch fancy combination
of flags if necessary (sadly we might miss the actual causer
flags as it might have already returned).
Btw, we perhaps would want to forward copied_seq in
somewhere or otherwise we might have some nice loop with
WARN stuff within but where to do that safely I don't
know at this stage until more is known (but it is not
made significantly worse by this patch).

net/atm: move all compat_ioctl handling to atm/ioctl.c
We have two implementations of the compat_ioctl handling for ATM, the
one that we have had for ages in fs/compat_ioctl.c and the one added to
net/atm/ioctl.c by David Woodhouse. Unfortunately, both versions are
incomplete, and in practice we use a very confusing combination of the
two.
For ioctl numbers that have the same identifier on 32 and 64 bit systems,
we go directly through the compat_ioctl socket operation, for those that
differ, we do a conversion in fs/compat_ioctl.c.
This patch moves both variants into the vcc_compat_ioctl() function,
while preserving the current behaviour. It also kills off the COMPATIBLE_IOCTL
definitions that we never use here.
Doing it this way is clearly not a good solution, but I hope it is a
step into the right direction, so that someone is able to clean up this
mess for real.

net/compat: fix dev_ifsioc emulation corner cases
Handling for SIOCSHWTSTAMP is broken on architectures
with a split user/kernel address space like s390,
because it passes a real user pointer while using
set_fs(KERNEL_DS).
A similar problem might arise the next time somebody
adds code to dev_ifsioc.
Split up dev_ifsioc into three separate functions for
SIOCSHWTSTAMP, SIOC*IFMAP and all other numbers so
we can get rid of set_fs in all potentially affected
cases.

DM9000: Wake on LAN support
Add support for Wake on LAN (WOL) reception and waking the device up from
this signal via the ethtool interface. Currently we are only supporting
the magic-packet variant of wakeup.
WOL is enabled by specifying a second interrupt resource to the driver
which indicates where the interrupt for the WOL is being signalled. This
then enables the necessary ethtool calls to leave the device in a state
to receive WOL frames when going into suspend.
