7dcdd073bf rtl8187: Fix lockups due to concurrent access to config routine
Some users of the RTL8187B have experienced difficulties since commit
49292d5635 that introduced the power
management wext hooks. This difficulty has not made much sense until
it was realized that it was possible for mac80211 to make a call to the
config routine while that routine was already being executed. On this
device, it is necessary to loopback the TX when changing channels. Unless
this is properly restored, the device will lockup. A mutex now protects
the device state, and the private data in several places.

The problem was found by Herton Ronaldo Krzesinski <herton@mandriva.com.br>,
who also suggested this type of fix.

bf4634afd8 rt2500pci: restoring missing line
In kernel version 2.6.26-rc9 my wireless LAN card worked; but in the
released 2.6.26, my RaLink rt2500 card wouldn't associate.

Git-bisect led me to this patch:

	61486e0f68
	rt2x00: Remove ieee80211_tx_control argument from write_tx_desc()

I believe that there is a problem with that patch --- it
(inadvertantly) removes an extra line of code, that used to set the
DATABYTE_COUNT field.

This patch reinstates that line, and with it my card works again.

The if-statement to determine the new TX/RX antenna

This is a correct event, since it can occur when only
one of the antenna's has been changed or when the new

00b1304c4c tcp: MD5: Fix IPv6 signatures
Reported by Stefanos Harhalakis; although 2.6.27-rc1 talks to itself using IPv6
TCP MD5 packets just fine, Stefanos noted that tcpdump claimed that the
signatures were invalid.

I broke this in 49a72dfb88 ("tcp: Fix MD5
signatures for non-linear skbs"), it was just a typo.

Note that tcpdump will still sometimes claim that the signatures are incorrect.
A patch to tcpdump has been submitted for this[1].

90b7e1120b tcp: MD5: Fix MD5 signatures on certain ACK packets
I noticed, looking at tcpdumps, that timewait ACKs were getting sent
with an incorrect MD5 signature when signatures were enabled.

I broke this in 49a72dfb88 ("tcp: Fix
MD5 signatures for non-linear skbs"). I didn't take into account that
the skb passed to tcp_*_send_ack was the inbound packet, thus the
source and dest addresses need to be swapped when calculating the MD5
pseudoheader.

77e2f14f71 ipv6: Fix ip6_xmit to send fragments if ipfragok is true
SCTP used ip6_xmit() to send fragments after received ICMP packet too
big message. But while send packet used ip6_xmit, the skb->local_df is
not initialized. So when skb if enter ip6_fragment(), the following
code will discard the skb.

ip6_fragment(...)
{
    if (!skb->local_df) {
        ...
        return -EMSGSIZE;
    }
    ...
}

SCTP do the following step:
1. send packet ip6_xmit(skb, ipfragok=0)
2. received ICMP packet too big message
3. if PMTUD_ENABLE: ip6_xmit(skb, ipfragok=1)

This patch fixed the problem by set local_df if ipfragok is true.

bc4768eb08 ipvs: Move userspace definitions to include/linux/ip_vs.h
Current versions of ipvsadm include "/usr/src/linux/include/net/ip_vs.h"
directly. This file also contains kernel-only definitions. Normally, public
definitions should live in include/linux, so this patch moves the
definitions shared with userspace to a new file, "include/linux/ip_vs.h".

This also removes the unused NFC_IPVS_PROPERTY bitmask, which was once
used to point into skb->nfcache.

To make old ipvsadms still compile with this, the old header file includes
the new one.

Thanks to Dave Miller and Horms for noting/adding the missing Kbuild entry

c3f26a269c netdev: Fix lockdep warnings in multiqueue configurations.
When support for multiple TX queues were added, the
netif_tx_lock() routines we converted to iterate over
all TX queues and grab each queue's spinlock.

This causes heartburn for lockdep and it's not a healthy

So modify this to use a top-level lock and a "frozen"
state for the individual TX queues.

967ab999a0 netfilter: xt_hashlimit: fix race between htable_destroy and htable_gc
Deleting a timer with del_timer doesn't guarantee, that the
timer function is not running at the moment of deletion. Thus
in the xt_hashlimit case we can get into a ticklish situation
when the htable_gc rearms the timer back and we'll actually
delete an entry with a pending timer.

Fix it with using del_timer_sync().

AFAIK del_timer_sync checks for the timer to be pending by
itself, so I remove the check.

a8ddc9163c netfilter: ipt_recent: fix race between recent_mt_destroy and proc manipulations
The thing is that recent_mt_destroy first flushes the entries
from table with the recent_table_flush and only *after* this
removes the proc file, corresponding to that table.

Thus, if we manage to write to this file the '+XXX' command we
will leak some entries. If we manage to write there a 'clean'
command we'll race in two recent_table_flush flows, since the
recent_mt_destroy calls this outside the recent_lock.

The proper solution as I see it is to remove the proc file first
and then go on with flushing the table. This flushing becomes
safe w/o the lock, since the table is already inaccessible from
the outside.

cba5cbd155 atm: fix const assignment/discard warnings in the ATM networking driver
Fix const assignment/discard warnings in the ATM networking driver.

The lane2_assoc_ind() function needed its arguments changing to match changes
in the lane2_ops struct (patch 61c33e0129
"atm: use const where reasonable").

697f8d0348 random32: seeding improvement
The rationale is:
   * use u32 consistently
   * no need to do LCG on values from (better) get_random_bytes
   * use more data from get_random_bytes for secondary seeding
   * don't reduce state space on srandom32()
   * enforce state variable initialization restrictions

Note: the second paper has a version of random32() with even longer period
and a version of random64() if needed.

4adf0af681 bridge: send correct MTU value in PMTU (revised)
When bridging interfaces with different MTUs, the bridge correctly chooses
the minimum of the MTUs of the physical devices as the bridges MTU.  But
when a frame is passed which fits through the incoming, but not through
the outgoing interface, a "Fragmentation Needed" packet is generated.

However, the propagated MTU is hardcoded to 1500, which is wrong in this
situation.  The sender will repeat the packet again with the same frame
size, and the same problem will occur again.

Instead of sending 1500, the (correct) MTU value of the bridge is now sent
via PMTU.  To achieve this, the corresponding rtable structure is stored
in its net_bridge structure.

Modified to get rid of fake_net_device as well.

68905eb4dc drivers/net/ehea/ehea_main.c: Release mutex in error handling code
The mutex is released on a successful return, so it would seem that it
should be released on an error return as well.

The semantic patch finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression l;
@@

mutex_lock(l);
... when != mutex_unlock(l)
    when any

    return ...;
}

b0ca2a21f7 sh_eth: Add support of SH7763 to sh_eth
SH7763 has Ethernet core same as SH7710/SH7712.
Positions of some registry are different, but the basic part is the same.
I add support of ethernet of sh7763 to sh_eth.
