f650470a8f ath5k: enable combined michael mic in key cache
For mac revisions >= "Griffin," the hardware allows the mic tx and rx
authenticator keys to share the same cache line, whereas earlier
hardware can only store the rx.  Enable the combined mic on hardware

6714349046 ath5k: clean up ath5k_hw_set_key
Status: O

With the addition of TKIP (and soon CCMP), key->alg is a more useful
guide to key type than the key length.

This patch cleans up key type assignment in ath5k_hw_set_key by
extracting it into its own function.  It also replaces the separate
memcpy() calls for extracting key material into the hardware format
with a loop that works regardless of key size.

Finally, the patch removes support for WEP-128 since it is a
non-standard key length that mac80211 also doesn't use.

f6bac3ea59 ath5k: preserve higher order bits when setting mac address
In some cases we would like to set the mac address without changing
the operating mode.  However, Atheros cards store PCU data in the high
16 bits of the mac address register.  Change ath5k_hw_set_lladdr() to
not clobber the PCU settings.

999890b21a net: /proc/net/ip_mr_cache, display Iif as a signed short
Today, iproute2 fails to show multicast forwarding unresolved cache
entries while scanning /proc/net/ip_mr_cache.

Indeed, it expects to see -1 in 'Iif' column to identify unresolved
entries but the kernel outputs 65535. It's a signed/unsigned issue:

'Iif', the source interface, is retrieved from member mfc_parent in
struct mfc_cache. mfc_parent is a vifi_t: unsigned short, but is
displayed in ipmr_mfc_seq_show() as "%-3d", signed integer.

In unresolevd entries, the 65535 value (0xFFFF) comes from this define:
#define ALL_VIFS    ((vifi_t)(-1))

That may explains why the guy who added support for this in iproute2
thought a -1 should be expected.

I don't know if this must be fixed in kernel or in iproute2. Who is
right? What is the correct API? How was it designed originally?

I let you decide if it should goes in the kernel or be fixed in iproute2.

1ea472e2de net: fix /proc/net/ip_mr_cache display - V2
/proc/net/ip_mr_cache and /proc/net/ip6_mr_cache displays garbage when
showing unresolved mfc_cache entries.

[root@qemu tests]# cat /proc/net/ip_mr_cache
Group    Origin   Iif     Pkts    Bytes    Wrong Oifs
014C00EF 010014AC 1         10    10050        0  2:1    3:1
024C00EF 010014AC 65535      514        2 -559067475

The first line is correct. It is a resolved cache entry, 10 packets used it...
The second line represents an unresolved entry, and the columns Pkts(4th),
Bytes(5th) and Wrong(6th) just show garbage.

In struct mfc_cache, there's an union to store data for resolved and
unresolved cases. And what ipmr_mfc_seq_show() is printing in these 
columns for the unresolved entries is some bytes from mfc_cache.mfc_un.res.
Bad.
(eg. In our case -559067475 is in fact 0xdead4ead which is the spinlock
magic from mfc_cache.mfc_un.unres.unresolved.lock.magic).

This patch replaces the garbage data written in these columns for the
unresolved entries by '0' (zeros) which is more correct.
This change doesn't break the ABI.

Also, mfc->mfc_un.res.pkt, mfc->mfc_un.res.bytes, mfc->mfc_un.res.wrong_if
are unsigned long.

It applies on top of net-next-2.6.

The patch for net-2.6 is slightly different because of the NIP6_FMT to
%pI6 conversion that was made in the seq_printf.

Changelog:
==========
V2:
* Instead of breaking the ABI by suppressing the columns that have no
  meaning for unresolved entries, fill them with 0 values.

8865c418ca atm: 32-bit ioctl compatibility
We lack compat ioctl support through most of the ATM code. This patch
deals with most of it, and I can now at least use BR2684 and PPPoATM
with 32-bit userspace.

I haven't added a .compat_ioctl method to struct atm_ioctl, because
AFAICT none of the current users need any conversion -- so we can just
call the ->ioctl() method in every case. I looked at br2684, clip, lec,
mpc, pppoatm and atmtcp.

In svc_compat_ioctl() the only mangling which is needed is to change
COMPAT_ATM_ADDPARTY to ATM_ADDPARTY. Although it's defined as
	_IOW('a', ATMIOC_SPECIAL+4,struct atm_iobuf)
it doesn't actually _take_ a struct atm_iobuf as an argument -- it takes
a struct sockaddr_atmsvc, which _is_ the same between 32-bit and 64-bit
code, so doesn't need conversion.

Almost all of vcc_ioctl() would have been identical, so I converted that
into a core do_vcc_ioctl() function with an 'int compat' argument.

I've done the same with atm_dev_ioctl(), where there _are_ a few
differences, but still it's relatively contained and there would
otherwise have been a lot of duplication.

I haven't done any of the actual device-specific ioctls, although I've
added a compat_ioctl method to struct atmdev_ops.

cb52deba12 forcedeth: power down phy when interface is down
Bring the physical link down when the interface is down by placing the PHY
in power-down state, unless WOL is enabled.  This mirrors the behavior of
other drivers including e1000 and tg3.

Without the patch, ifconfig down leaves the physical link up, which confuses
datacenter users who expect the link lights both on the NIC and the switch to
go out when they bring an interface down.

Furthermore, even though the phy is powered on, autonegotiation stops working,
so a normally gigabit link might suddenly become 100 Mbit half-duplex when the
interface goes down, and become gigabit when it comes up again.

Ayaz said:

  I would not include this patch until further testing is performed.  NVIDIA
  MCP chips use 3rd party PHY vendors.  By powering down the phy, it could
  have adverse affects on certain phys.

d81d228567 xfrm: Accept XFRM_STATE_AF_UNSPEC SAs on IPv4/IPv6 only hosts
Installing SAs using the XFRM_STATE_AF_UNSPEC fails on hosts with
support for one address family only. This patch accepts such SAs, even
if the processing of not supported packets will fail.

d5654efd3f xfrm: Fix kernel panic when flush and dump SPD entries
After flush the SPD entries, dump the SPD entries will cause kernel painc.

Used the following commands to reproduct:

- echo 'spdflush;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64  any -P out ipsec \
  ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
  spddump;' | setkey -c
- echo 'spdflush; spddump;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64  any -P out ipsec \
  ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
  spddump;' | setkey -c

This is because when flush the SPD entries, the SPD entry is not remove
from the list.

This patch fix the problem by remove the SPD entry from the list.
