c22eb87b57 [PATCH] rt2x00: Allways memset memory obtained from skb_push()
When skb_push() is used we should memset the memory before
usage. This will prevent bugs which could occur when the
data is treated as TX descriptor.

By defining rt73usb_get_tsf to NULL we only
have 1 location that needs to be edited
when rt73usb_get_tsf can be enabled again.
This also reduces the number of #ifdefs in

5c58ee51ff [PATCH] rt2x00: Reorganize configuration handler
Reorganize configuration handling by creating a extra
structure which contains precalculated values based
on the mac80211 values which are usefull for all
individual drivers.

This also fixes the preamble configuration problem,
up untill now preamble was never configured since
by default the rate->val value was used when changing
the mode.
Now rate->val will only be used to set the basic rate mask.
The preamble configuration will now be done correctly
through the erp_ie_changed callback function.

81873e9ccd [PATCH] rt2x00: Fix rfkill handling
As reported by Modestas Vainius, enabling rkfill in 1 driver and
disabling it in a second could cause a NULL pointer exception when
the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag.

Furthermore, rfkill expects the timeout as a value in milliseconds
instead of jiffies. Also increase the timeout to a second,
since this 250ms would be overkill.

Also the flag DEVICE_ENABLED_RADIO_HW is causing problems
for devices which do not support the hardware button
while rfkill is enabled in the driver.

To remidy this we should inverse the flag and its meaning,
rename the flag to DEVICE_DISABLED_RADIO_HW this means that
by default the radio is enabled by the hardware button (if present)
and can only be disabled explicitely.

ipw2200 makes extensive use of background scanning when unassociated or
down.  Unfortunately, the firmware sends scan completed events many
times per second, which the driver pushes directly up to userspace.
This needlessly wakes up processes listening for wireless events many
times per second.  Batch together scan completed events for
non-user-requested scans and send them up to userspace every 4 seconds.
Scan completed events resulting from an SIOCSIWSCAN call are pushed up
without delay.

050f009e16 [IPSEC]: Lock state when copying non-atomic fields to user-space
This patch adds locking so that when we're copying non-atomic fields such as
life-time or coaddr to user-space we don't get a partial result.

For af_key I've changed every instance of pfkey_xfrm_state2msg apart from
expiration notification to include the keys and life-times.  This is in-line
with XFRM behaviour.

The actual cases affected are:

* pfkey_getspi: No change as we don't have any keys to copy.
* key_notify_sa:
	+ ADD/UPD: This wouldn't work otherwise.
	+ DEL: It can't hurt.

68325d3b12 [XFRM] user: Move attribute copying code into copy_to_user_state_extra
Here's a good example of code duplication leading to code rot.  The
notification patch did its own netlink message creation for xfrm states.
It duplicated code that was already in dump_one_state.  Guess what, the
next time (and the time after) when someone updated dump_one_state the
notification path got zilch.

This patch moves that code from dump_one_state to copy_to_user_state_extra
and uses it in xfrm_notify_sa too.  Unfortunately whoever updates this
still needs to update xfrm_sa_len since the notification path wants to
know the exact size for allocation.

At least I've added a comment saying so and if someone still forgest, we'll
have a WARN_ON telling us so.

I also changed the security size calculation to use xfrm_user_sec_ctx since
that's what we actually put into the skb.  However it makes no practical
difference since it has the same size as xfrm_sec_ctx.

658b219e93 [IPSEC]: Move common code into xfrm_alloc_spi
This patch moves some common code that conceptually belongs to the xfrm core
from af_key/xfrm_user into xfrm_alloc_spi.

In particular, the spin lock on the state is now taken inside xfrm_alloc_spi.
Previously it also protected the construction of the response PF_KEY/XFRM
messages to user-space.  This is inconsistent as other identical constructions
are not protected by the state lock.  This is bad because they in fact should
be protected but only in certain spots (so as not to hold the lock for too
long which may cause packet drops).

The SPI byte order conversion has also been moved.

007f0211a8 [IPSEC]: Store IPv6 nh pointer in mac_header on output
Current the x->mode->output functions store the IPv6 nh pointer in the
skb network header.  This is inconvenient because the network header then
has to be fixed up before the packet can leave the IPsec stack.  The mac
header field is unused on output so we can use that to store this instead.

This patch does that and removes the network header fix-up in xfrm_output.

It also uses ipv6_hdr where appropriate in the x->type->output functions.

There is also a minor clean-up in esp4 to make it use the same code as
esp6 to help any subsequent effort to merge the two.

Lastly it kills two redundant skb_set_* statements in BEET that were
simply copied over from transport mode.

	foo(x);

tend to be broken because foo is either synchronous where this is totally

In the case of xfrm_secpath_reject, the function is synchronous and therefore
we should just kill the reference count.

4665079cbb [NETNS]: Move some code into __init section when CONFIG_NET_NS=n
With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.

Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.

The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.

I recently noticed that when calling:

# ethtool -s eth0 autoneg on

on a 5722 (though I'm sure it's not specific to that card) that
subsequent checks of the cards status looked like this:

# ethtool eth0
Settings for eth0:
        Supported ports: [ MII ]
        Supported link modes:   10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Half 1000baseT/Full
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full
                                100baseT/Half 100baseT/Full
                                1000baseT/Half 1000baseT/Full
        Advertised auto-negotiation: No        <---- This seems odd?!?
        Speed: 1000Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: on
        Supports Wake-on: g
        Wake-on: d
        Current message level: 0x000000ff (255)
        Link detected: yes

I noticed that the following commit:

commit 3600d918d8
Author: Michael Chan <mchan@broadcom.com>
Date:   Thu Dec 7 00:21:48 2006 -0800

    [TG3]: Allow partial speed advertisement.

    Honor the advertisement bitmask from ethtool.  We used to always
    advertise the full capability when autoneg was set to on.

changed things around so that ethtool speed settings were strictly
followed.  Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg
in the advertising field (and maybe it shouldn't have to).  I'd vote
that it should be fixed there, but it should also be added here just in
case someone using ethtool ioctls in their own application gets what
they want.

Adding that flag in tg3_set_settings seemed like the most logical place
since the driver works fine on boot.  This is just an issue when
re-enabling autonegotiation, so we should probably nip it there.

14e3e07979 [NET]: split dev_ifsioc() according to locking
This always bugged me: dev_ioctl() called dev_ifsioc() either inside
read_lock(dev_base_lock) or rtnl_lock(), depending on the ioctl being
executed.

This change moves the ioctls executed inside dev_base_lock to a new
function, dev_ifsioc_locked().  Now the locking context is completely
clear to the reader.

cfcabdcc2d [NET]: sparse warning fixes
Fix a bunch of sparse warnings. Mostly about 0 used as
NULL pointer, and shadowed variable declarations.
One notable case was that hash size should have been unsigned.

This should no longer be necessary because fackets_out is

29d0a309d1 [TCP]: Fix two off-by-one errors in fackets_out adjusting logic
1) Passing wrong skb to tcp_adjust_fackets_out could corrupt
fastpath_cnt_hint as tcp_skb_pcount(next_skb) is not included
to it if hint points exactly to the next_skb (it's lagging
behind, see sacktag).

2) When fastpath_skb_hint is put backwards to avoid dangling
skb reference, the skb's pcount must also be removed from count
(not included like above).
