Currently the last packet of a connection isn't accounted when its causing
abnormal termination.
Introduces nf_ct_kill_acct() which increments the accounting counters on
conntrack kill. The new function was necessary, because there are calls
to nf_ct_kill() which don't need accounting:
nf_conntrack_proto_tcp.c line ~847:
Kills ct and returns NF_REPEAT. We don't want to count twice.
nf_conntrack_proto_tcp.c line ~880:
Kills ct and returns NF_DROP. I think we don't want to count dropped
packets.
nf_conntrack_netlink.c line ~824:
As far as I can see ctnetlink_del_conntrack() is used to destroy a
conntrack on behalf of the user. There is an sk_buff, but I don't think
this is an actual packet. Incrementing counters here is therefore not
desired.

control rules
The following patch implements a new "security" table for iptables, so
that MAC (SELinux etc.) networking rules can be managed separately to
standard DAC rules.
This is to help with distro integration of the new secmark-based
network controls, per various previous discussions.
The need for a separate table arises from the fact that existing tools
and usage of iptables will likely clash with centralized MAC policy
management.
The SECMARK and CONNSECMARK targets will still be valid in the mangle
table to prevent breakage of existing users.

The purpose of nla_parse_nested_compat() is to parse attributes which
contain a struct followed by a stream of nested attributes. So far,
it called nla_parse_nested() to parse the stream of nested attributes
which was wrong, as nla_parse_nested() expects a container attribute
as data which holds the attribute stream. It needs to call
nla_parse() directly while pointing at the next possible alignment
point after the struct in the beginning of the attribute.
With this patch, I can no longer reproduce the reported leftover
warnings.

Since commit e38bad4766a110b61fa6038f10be16ced8c6cc38
mac80211: make ieee80211_iterate_active_interfaces not need rtnl
rt2500usb and rt73usb broke down due to attempting register access
in atomic context (which is not possible for USB hardware).
This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock,
and provides the non-RTNL version under a new name:
ieee80211_iterate_active_interfaces_atomic()
So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those
drivers require the RTNL version of ieee80211_iterate_active_interfaces().
Since they already call that function directly, this patch will automatically
fix the USB rt2x00 drivers.

There was some cleanup issues during early mount which would trigger
a kernel bug for certain types of failure. This patch reorganizes the
cleanup to get rid of the bad behavior.
This also merges the 9pnet and 9pnet_fd modules for the purpose of
configuration and initialization. Keeping the fd transport separate
from the core 9pnet code seemed like a good idea at the time, but in
practice has caused more harm and confusion than good.

trying to clean up the signal/noise code. the previous code in mac80211 had
confusing names for the related variables, did not have much definition of
what units of signal and noise were provided and used implicit mechanisms from
the wireless extensions.
this patch introduces hardware capability flags to let the hardware specify
clearly if it can provide signal and noise level values and which units it can
provide. this also anticipates possible new units like RCPI in the future.
for signal:
IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific
IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point
IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW
for noise we currently only have dBm:
IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW
if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has
to provide the maximum value (max_signal) it reports in order for applications
to make sense of the signal values.
i tried my best to find out for each driver what it can provide and update it
but i'm not sure (?) for some of them and used the more conservative guess in
doubt. this can be fixed easily after this patch has been merged by changing
the hardware flags of the driver.

This adds a new flag to the ieee80211_key_conf structure.
This flag will inform the driver the key is pairwise rather then
a shared key.
This is important for drivers who support both types of keys,
and need to be informed which type of key this is. Alternative
would be drivers checking the address argument of set_key(),
but it will be safer when mac80211 is more explicit.

The hw_key_idx inside the ieee80211_key_conf structure does
not provide all the information drivers might need to perform
hardware encryption.
This is in particular true for rt2x00 who needs to know the
key algorithm and whether it is a shared or pairwise key.
By passing the ieee80211_key_conf pointer it assures us that
drivers can make full use of all information that it should know
about a particular key.
Additionally this patch updates all drivers to grab the hw_key_idx from
the ieee80211_key_conf structure.

Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure

As it stands it's impossible to use any authentication algorithms
with an ID above 31 portably. It just happens to work on x86 but
fails miserably on ppc64.
The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.
After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature. For current
applications, the best solution IMHO is to allow all algorithms when
the bit masks are all ~0.
The following patch does exactly that.
This bug was identified by IBM when testing on the ppc64 platform
using the NULL authentication algorithm which has an ID of 251.

As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.
Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
`- tcp_v4_syn_recv_sock
`- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.

There is no need to send BSS changes to driver from beacons processed
during scanning. We are more interested in beacons from an AP with which
we are associated - these will still be used to send updates to driver as
the beacons are received without scanning.
This change·removes the requirement that bss_info_changed needs to be atomic.
The beacons received during scanning are processed from a tasklet, but if we
do not call bss_info_changed for these beacons there is no need for it to be
atomic. This function (bss_info_changed) is called either from workqueue or
ioctl in all other instances.
