8462fe3cd9 [PATCH] softmac: suggest per-frame-type TX rate
This patch is the first step towards rate control inside softmac.

The txrates substructure has been extended to provide
different fields for different types of packets (management/data,
unicast/multicast). These fields are updated on association to values
compatible with the access point we are associating to.

Drivers can then use the new ieee80211softmac_suggest_txrate() function
call when deciding which rate to transmit each frame at. This is
immensely useful for ZD1211, and bcm can use it too.

The user can still specify a rate through iwconfig, which is matched
for all transmissions (assuming the rate they have specified is in
the rate set required by the AP).

At a later date, we can incorporate automatic rate management into
the ieee80211softmac_recalc_txrates() function.

This patch also removes the mcast_fallback field. Sam Leffler pointed
out that this field is meaningless, because no driver will ever be
retransmitting mcast frames (they are not acked).

461c078c9c [PATCH] orinoco: don't put PCI resource data to the network device
The resource data in the network device is intended for ISA and other
older busses, but not for PCI.  Don't put PCI data there.  Don't (ab)use
the network device for keeping the IRQ number.

Retire orinoco_pci_setup_netdev(), and print some minimal information to
the kernel log instead, identifying the network device and the driver
mostly to identify problems at startup.  Scripts should rely on sysfs.

airo_test_wpa_capable assumes that the softSubVer part of the firmware

869aaab181 [PATCH] bcm43xx: Fix array overrun in bcm43xx_geo_init
The problem here is that the bcm34xx driver and the ieee80211
stack do not agree on what channels are possible for 802.11a.
The ieee80211 stack only wants channels between 34 and 165, while
the bcm43xx driver accepts anything from 0 to 200. I made the
bcm43xx driver comply with the ieee80211 stack expectations, by
using the proper constants.

d57336e3f2 [PATCH] softmac: make non-operational after being stopped
zd1211 with softmac and wpa_supplicant revealed an issue with softmac
and the use of workqueues. Some of the work functions actually
reschedule themselves, so this meant that there could still be
pending work after flush_scheduled_work() had been called during
ieee80211softmac_stop().

This patch introduces a "running" flag which is used to ensure that
rescheduling does not happen in this situation.

I also used this flag to ensure that softmac's hooks into ieee80211 are
non-operational once the stop operation has been started. This simply
makes softmac a little more robust, because I could crash it easily
by receiving frames in the short timeframe after shutting down softmac
and before turning off the ZD1211 radio. (ZD1211 is now fixed as well!)

995c99268e [PATCH] softmac: don't reassociate if user asked for deauthentication
When wpa_supplicant exits, it uses SIOCSIWMLME to request
deauthentication.  softmac then tries to reassociate without any user
intervention, which isn't the desired behaviour of this signal.

This change makes softmac only attempt reassociation if the remote
network itself deauthenticated us.

rather just other level1 routers.  (I hope the patch is clearer than

75c2d9077c [TCP]: Fix sock_orphan dead lock
Calling sock_orphan inside bh_lock_sock in tcp_close can lead to dead
locks.  For example, the inet_diag code holds sk_callback_lock without
disabling BH.  If an inbound packet arrives during that admittedly tiny
window, it will cause a dead lock on bh_lock_sock.  Another possible
path would be through sock_wfree if the network device driver frees the
tx skb in process context with BH enabled.

We can fix this by moving sock_orphan out of bh_lock_sock.

The tricky bit is to work out when we need to destroy the socket
ourselves and when it has already been destroyed by someone else.

By moving sock_orphan before the release_sock we can solve this
problem.  This is because as long as we own the socket lock its
state cannot change.

So we simply record the socket state before the release_sock
and then check the state again after we regain the socket lock.
If the socket state has transitioned to TCP_CLOSE in the time being,
we know that the socket has been destroyed.  Otherwise the socket is
still ours to keep.

Note that I've also moved the increment on the orphan count forward.
This may look like a problem as we're increasing it even if the socket
is just about to be destroyed where it'll be decreased again.  However,
this simply enlarges a window that already exists.  This also changes
the orphan count test by one.

Considering what the orphan count is meant to do this is no big deal.

This problem was discoverd by Ingo Molnar using his lock validator.

6fd737031e [NETFILTER]: H.323 helper: fix endless loop caused by invalid TPKT len
When the TPKT len included in the packet is below the lowest valid value
of 4 an underflow occurs which results in an endless loop.

Found by testcase 0000058 from the PROTOS c07-h2250v4 testsuite.

a0548871ed [PATCH] splice: redo page lookup if add_to_page_cache() returns -EEXIST
This can happen quite easily, if several processes are trying to splice
the same file at the same time. It's not a failure, it just means someone
raced with us in allocating this file page. So just dump the allocated
page and relookup the original.

1432873af7 [PATCH] splice: LRU fixups
Nick says that the current construct isn't safe. This goes back to the
original, but sets PIPE_BUF_FLAG_LRU on user pages as well as they all
seem to be on the LRU in the first place.
