tg3 devices will need to know exactly what function number they are so
that they can communicate their status to the other functions. In a KVM
environment, the function number of a device presented by the kernel
might not be the true function number, so an alternative method to

This patch used to contain an implementation for the alternative method,
but recently we discovered a hardware bug that renders it incorrect.
While new method is not yet known, it is still useful to consolidate the
code that determines the PCI function to one location and use the

Entering into D0 is a requirement for correct operation of tg3 devices
though. If the PCI layer should be changed to return an error code for
this type of failure, the tg3 driver would be interested in catching it
and reacting to it. This patch makes the necessary modifications.

This patch contains a few misc fixes which resolve a recently
reported issue. This patch has been a real team effort and has
received a lot of testing.
The first issue is that the ail lock needs to be held over a few
more operations. The lock thats added into gfs2_releasepage() may
possibly be a candidate for replacing with RCU at some future
point, but at this stage we've gone for the obvious fix.
The second issue is that gfs2_write_inode() can end up calling
a glock recursively when called from gfs2_evict_inode() via the
syncing code, so it needs a guard added.
The third issue is that we either need to not truncate the metadata
pages of inodes which have zero link count, but which we cannot
deallocate due to them still being in use by other nodes, or we need
to ensure that those pages have all made it through the journal and
ail lists first. This patch takes the former approach, but the
latter has also been tested and there is nothing to choose between
them performance-wise. So again, we could revise that decision
in the future.
Also, the inode eviction process is now better documented.

Attached is a patch which addresses a race condition in the DVB core
related to closing/reopening the DVB frontend device in quick
succession. This is the reason that devices such as the HVR-1300,
HVR-3000, and HVR-4000 have been failing to scan properly under MythTV
and w_scan.
The gory details of the race are described in the patch.
Devin
There is a race condition exhibited when channel scanners such as w_scan and
MythTV quickly close and then reopen the frontend device node.
Under normal conditions, the behavior is as follows:
1. Application closes the device node
2. DVB frontend ioctl calls dvb_frontend_release which sets
fepriv->release_jiffies
3. DVB frontend thread *eventually* calls dvb_frontend_is_exiting() which
compares fepriv->release_jiffies, and shuts down the thread if timeout has
expired
4. Thread goes away
5. Application opens frontend device
6. DVB frontend ioctl() calls ts_bus_ctrl(1)
7. DVB frontend ioctl() creates new frontend thread, which calls
dvb_frontend_init(), which has demod driver init() routine setup initial
register state for demod chip.
8. Tuning request is issued.
The race occurs when the application in step 5 performs the new open() call
before the frontend thread is shutdown. In this case the ts_bus_ctrl() call
is made, which strobes the RESET pin on the demodulator, but the
dvb_frontend_init() function never gets called because the frontend thread
hasn't gone away yet. As a result, the initial register config for the demod
is *never* setup, causing subsequent tuning requests to fail.
If there is time between the close and open (enough for the dvb frontend
thread to be torn down), then in that case the new frontend thread is created
and thus the dvb_frontend_init() function does get called.
The fix is to set the flag which forces reinitialization if we did in fact
call ts_bus_ctrl().
This problem has been seen on the HVR-1300, HVR-3000, and HVR-4000, and is
likely occuring on other designs as well where ts_bus_ctrl() actually strobes
the reset pin on the demodulator.
Note that this patch should supercede any patches submitted for the
1300/3000/4000 which remove the code that removes GPIO code in
cx8802_dvb_advise_acquire(), which have been circulating by users for some
time now...

In WoWLAN, devices may use crypto keys for TX/RX
and could also implement GTK rekeying. If the
driver isn't able to retrieve replay counters and
similar information from the device upon resume,
or if the device isn't responsive due to platform
issues, it isn't safe to keep the connection up
as GTK rekey messages from during the sleep time
could be replayed against it.
The only protection against that is disconnecting
from the AP. Modifying mac80211 to do that while
it is resuming would be very complex and invasive
in the case that the driver requires a reconfig,
so do it after it has resumed completely. In that
case, however, packets might be replayed since it
can then only happen after TX/RX are up again, so
mark keys for interfaces that need to disconnect
as "tainted" and drop all packets that are sent
or received with those keys.
