Currently the bridge multicast snooping feature periodically issues
IPv6 general multicast listener queries to sense the absence of a
listener.
For this, it uses :: as its source address - however RFC 2710 requires:
"To be valid, the Query message MUST come from a link-local IPv6 Source
Address". Current Linux kernel versions seem to follow this requirement
and ignore our bogus MLD queries.
With this commit a link local address from the bridge interface is being
used to issue the MLD query, resulting in other Linux devices which are
multicast listeners in the network to respond with a MLD response (which
was not the case before).

Map the IPv6 header's destination multicast address to an ethernet
source address instead of the MLD queries multicast address.
For instance for a general MLD query (multicast address in the MLD query
set to ::), this would wrongly be mapped to 33:33:00:00:00:00, although
an MLD queries destination MAC should always be 33:33:00:00:00:01 which
matches the IPv6 header's multicast destination ff02::1.

Currently the multicast bridge snooping support is not active for
link local multicast. I assume this has been done to leave
important multicast data untouched, like IPv6 Neighborhood Discovery.
In larger, bridged, local networks it could however be desirable to
optimize for instance local multicast audio/video streaming too.
With the transient flag in IPv6 multicast addresses we have an easy
way to optimize such multimedia traffic without tempering with the
high priority multicast data from well-known addresses.
This patch alters the multicast bridge snooping for IPv6, to take
effect for transient multicast addresses instead of non-link-local
addresses.

We actually want a pointer to the grec_nsrcr and not the following
field. Otherwise we can get very high values for *nsrcs as the first two
bytes of the IPv6 multicast address are being used instead, leading to
a failing pskb_may_pull() which results in MLDv2 reports not being
parsed.

The protocol type for IPv6 entries in the hash table for multicast
bridge snooping is falsely set to ETH_P_IP, marking it as an IPv4
address, instead of setting it to ETH_P_IPV6, which results in negative
look-ups in the hash table later.

Linux-next as of 20110217 complains when building for OMAP1.

A recent patch by Gustavo (Bluetooth: Merge L2CAP and SCO modules

function in the error path of bt_init.

The current implementation of hidp_output_raw_report() relies only on
the Control channel even for Output reports, and the BT HID
specification [1] does not mention using the DATA message for Output
reports on the Control channel (see section 7.9.1 and also Figure 11:
SET_ Flow Chart), so let us just use SET_REPORT.
This also fixes sending Output reports to some devices (like Sony
Sixaxis) which are not able to handle DATA messages on the Control
channel.
Ideally hidp_output_raw_report() could be improved to use this scheme:
Feature Report -- SET_REPORT on the Control channel
Output Report -- DATA on the Interrupt channel
for more efficiency, but as said above, right now only the Control
channel is used.

All of the places that need to call mgmt_pending_remove already have a
pointer to the pending command, so searching for the command in the list
doesn't make sense. The added benefit is that many places that
previously had to call list_del + mgmt_pending_free can just call
mgmt_pending_remove now.

To properly track bonding completion an event to indicate authentication
failure is needed. This event will be sent whenever an authentication
complete HCI event with a non-zero status comes. It will also be sent
when we're acting in acceptor role for SSP authentication in which case

I previously managed to reproduce a hang while scanning wireless

Fix a bug that undo_retrans is incorrectly decremented when undo_marker is
not set or undo_retrans is already 0. This happens when sender receives
more DSACK ACKs than packets retransmitted during the current
undo phase. This may also happen when sender receives DSACK after
the undo operation is completed or cancelled.
Fix another bug that undo_retrans is incorrectly incremented when
sender retransmits an skb and tcp_skb_pcount(skb) > 1 (TSO). This case
is rare but not impossible.

From: Eric W. Biederman <ebiederm@xmission.com>
In the beginning with batching unreg_list was a list that was used only
once in the lifetime of a network device (I think). Now we have calls
using the unreg_list that can happen multiple times in the life of a
network device like dev_deactivate and dev_close that are also using the
unreg_list. In addition in unregister_netdevice_queue we also do a
list_move because for devices like veth pairs it is possible that
unregister_netdevice_queue will be called multiple times.
So I think the change below to fix dev_deactivate which Eric D. missed
will fix this problem. Now to go test that.

Eric W. Biederman reported a lockdep splat in inet_twsk_deschedule()
This is caused by inet_twsk_purge(), run from process context,
and commit 575f4cd5a5b6394577 (net: Use rcu lookups in inet_twsk_purge.)
removed the BH disabling that was necessary.
Add the BH disabling but fine grained, right before calling
inet_twsk_deschedule(), instead of whole function.
