The kernel's implementation of notifier chains is unsafe. There is no
protection against entries being added to or removed from a chain while the
chain is in use. The issues were discussed in this thread:
http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2
We noticed that notifier chains in the kernel fall into two basic usage
classes:
"Blocking" chains are always called from a process context
and the callout routines are allowed to sleep;
"Atomic" chains can be called from an atomic context and
the callout routines are not allowed to sleep.
We decided to codify this distinction and make it part of the API. Therefore
this set of patches introduces three new, parallel APIs: one for blocking
notifiers, one for atomic notifiers, and one for "raw" notifiers (which is
really just the old API under a new name). New kinds of data structures are
used for the heads of the chains, and new routines are defined for
registration, unregistration, and calling a chain. The three APIs are
explained in include/linux/notifier.h and their implementation is in
kernel/sys.c.
With atomic and blocking chains, the implementation guarantees that the chain
links will not be corrupted and that chain callers will not get messed up by
entries being added or removed. For raw chains the implementation provides no
guarantees at all; users of this API must provide their own protections. (The
idea was that situations may come up where the assumptions of the atomic and
blocking APIs are not appropriate, so it should be possible for users to
handle these things in their own way.)
There are some limitations, which should not be too hard to live with. For
atomic/blocking chains, registration and unregistration must always be done in
a process context since the chain is protected by a mutex/rwsem. Also, a
callout routine for a non-raw chain must not try to register or unregister
entries on its own chain. (This did happen in a couple of places and the code
had to be changed to avoid it.)
Since atomic chains may be called from within an NMI handler, they cannot use
spinlocks for synchronization. Instead we use RCU. The overhead falls almost
entirely in the unregister routine, which is okay since unregistration is much
less frequent that calling a chain.
Here is the list of chains that we adjusted and their classifications. None
of them use the raw API, so for the moment it is only a placeholder.
ATOMIC CHAINS
-------------
arch/i386/kernel/traps.c: i386die_chain

BLOCKING CHAINS
---------------
arch/powerpc/platforms/pseries/reconfig.c: pSeries_reconfig_chain
arch/s390/kernel/process.c: idle_chain
arch/x86_64/kernel/process.c idle_notifier
drivers/base/memory.c: memory_chain

kernel/sys.c reboot_notifier_list
net/core/dev.c netdev_chain
net/decnet/dn_dev.c: dnaddr_chain
net/ipv4/devinet.c: inetaddr_chain
It's possible that some of these classifications are wrong. If they are,
please let us know or submit a patch to fix them. Note that any chain that
gets called very frequently should be atomic, because the rwsem read-locking
used for blocking chains is very likely to incur cache misses on SMP systems.
(However, if the chain's callout routines may sleep then the chain cannot be
atomic.)

It seems to me that the today's wireless-2.6 git contains bcm43xx which
does not free txb's correctly, if I understand it right.
Consider a situation where a txb with two skb's is sent down.
The dma_tx_fragment will save the pointer to meta->txb of the first
fragment. If fragments are freed in order, ieee80211_txb_free frees both
skb's when the first fragment is processed. This may result in reuse
of the second skb's memory.
This danger is rather remote, but it seems to me that the patch
below not only fixes the problem, but also makes the code simpler,
which is good, right?

When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all. The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().
This patch is a kernel-wide sweep of all instances of NR_CPUS. I found very
few instances of this bug, if any. But the patch converts lots of open-coded
test to use the preferred helper macros.

This is version 20 of the Wireless Extensions. This is the
completion of the RtNetlink work I started early 2004, it enables the
full Wireless Extension API over RtNetlink.
Few comments on the patch :
o totally driver transparent, no change in drivers needed.
o iwevent were already RtNetlink based since they were created
(around 2.5.7). This adds all the regular SET and GET requests over
RtNetlink, using the exact same mechanism and data format as iwevents.
o This is a Kconfig option, as currently most people have no
need for it. Surprisingly, patch is actually small and well
encapsulated.
o Tested on SMP, attention as been paid to make it 64 bits clean.
o Code do probably too many checks and could be further
optimised, but better safe than sorry.
o RtNetlink based version of the Wireless Tools available on
my web page for people inclined to try out this stuff.
I would also like to thank Alexey Kuznetsov for his helpful
suggestions to make this patch better.

We're now starting to have quite a number of places that do skb_pull
followed immediately by an skb_postpull_rcsum. We can merge these two
operations into one function with skb_pull_rcsum. This makes sense
since most pull operations on receive skb's need to update the
checksum.
I've decided to make this out-of-line since it is fairly big and the
fast path where hardware checksums are enabled need to call
csum_partial anyway.
Since this is a brand new function we get to add an extra check on the
len argument. As it is most callers of skb_pull ignore its return
value which essentially means that there is no check on the len
argument.

Move the netif_carrier_off() call from tg3_init_one()->
tg3_init_link_config() to tg3_open() as is the convention for most other
network drivers.
I was getting a panic after a tg3 device failed to initialize due to DMA
failure. The oops pointed to the link watch queue with spinlock debugging
enabled. Without spinlock debugging, the Oops didn't occur.
I suspect that the link event was getting queued but not executed until
after the DMA test had failed and the device was freed. The link event was
then operating on freed memory, which could contain anything. With this
patch applied, the Oops no longer occurs.

Support WoL during shutdown by calling
tg3_set_power_state(tp, PCI_D3hot) during tg3_close().
Change the power state parameter to pci_power_t type and use
constants defined in pci.h.
Certain ethtool operations cannot be performed after tg3_close()
because the device will go to low power state. Add return -EAGAIN
in such cases where appropriate.

Leave TSO off by default on older chips that do firmware TSO because
performance is slightly lower.

Sun does't put an SEEPROM behind the tigon3 chip, among other things,
so accesses to these areas just give bus timeouts.

The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.
For example, some 4-port card or mother board designs have 5704 behind
the 5714.
All devices behind the EPB require the 40-bit DMA workaround.
Thanks to Chris Elmquist again for reporting the problem and testing
the patch.

This patch modifies the driver to support the ipw2200-fw-3.0 image format.
The 3.0 fw image does not add any new capabilities, but as a result of
image format changes, it should fix two problems experienced by users:
1) Race conditions with the request_firmware interface and udev/hotplug
are improved as only a single request_firmware call is now required to
load the firmware and microcode (vs. 3 separate calls previously)
2) The monitor mode firmware (sniffer) is now packaged with the correct
boot image so it can now function without frequent restarts.
Note: Once you apply this patch, you will also need to upgrade your
firmware image to the 3.0 version available from:

significantly quieter in one than the other. It favors the quieter
antenna, and won't kick in unless the difference is significant.
