drivers/isdn/mISDN/stack.c: remove invalid reference to list iterator variable

2012-07-09T22:24:33+00:00

If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure.  Thus this value should not be used after
the end of the iterator.  The dereferences are just deleted from the
debugging statement.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

"Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.

It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.

There are also lots of new drivers, pimarily gadget, but others as
well. We deleted a staging driver, which was nice, and finally
dropped the obsolete usbfs code, which will make Al happy to never
have to touch that again.

There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

USB: Disable hub-initiated LPM for comms devices.

2012-05-18T22:42:55+00:00

Hub-initiated LPM is not good for USB communications devices.  Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.

If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data.  Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.

The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host.  In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.

Set the disable_hub_initiated_lpm flag for for all USB communications
drivers.  I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

isdn: remove duplicate NULL check

2012-05-17T08:47:50+00:00

We test both "!skb_out" and "skb_out" here which is duplicative and
causes a static checker warning.  I considered that the intent might
have been to test "skb_in" but that's a valid pointer here.

mISDN: Allow to set a minimum length for transparent data

2012-05-16T19:23:46+00:00

If the FIFO of the card is small, many short messages are queued up to
the upper layers and the userspace. This change allows the applications
to set a minimum datalen they want from the drivers.
Create a common control function to avoid code duplication in each
driver.
