During a reset, releasing the swflag after it failed to be acquired would
cause a double unlock of the mutex.  Instead, test whether acquisition of
the swflag was successful and if not, do not release the swflag.  The reset
must still be done to bring the device to a quiescent state.

	A few months back a race was discused between the netpoll napi service
path, and the fast path through net_rx_action:
http://kerneltrap.org/mailarchive/linux-netdev/2007/10/16/345470

A patch was submitted for that bug, but I think we missed a case.

Consider the following scenario:

INITIAL STATE
CPU0 has one napi_struct A on its poll_list
CPU1 is calling netpoll_send_skb and needs to call poll_napi on the same
napi_struct A that CPU0 has on its list



CPU0						CPU1
net_rx_action					poll_napi
!list_empty (returns true)			locks poll_lock for A
						 poll_one_napi
						  napi->poll
						   netif_rx_complete
						    __napi_complete
						    (removes A from poll_list)
list_entry(list->next)


In the above scenario, net_rx_action assumes that the per-cpu poll_list is
exclusive to that cpu.  netpoll of course violates that, and because the netpoll
path can dequeue from the poll list, its possible for CPU0 to detect a non-empty
list at the top of the while loop in net_rx_action, but have it become empty by
the time it calls list_entry.  Since the poll_list isn't surrounded by any other
structure, the returned data from that list_entry call in this situation is
garbage, and any number of crashes can result based on what exactly that garbage
is.

Given that its not fasible for performance reasons to place exclusive locks
arround each cpus poll list to provide that mutal exclusion, I think the best
solution is modify the netpoll path in such a way that we continue to guarantee
that the poll_list for a cpu is in fact exclusive to that cpu.  To do this I've
implemented the patch below.  It adds an additional bit to the state field in
the napi_struct.  When executing napi->poll from the netpoll_path, this bit will
be set. When a driver calls netif_rx_complete, if that bit is set, it will not
remove the napi_struct from the poll_list.  That work will be saved for the next
iteration of net_rx_action.

I've tested this and it seems to work well.  About the biggest drawback I can
see to it is the fact that it might result in an extra loop through
net_rx_action in the event that the device is actually contended for (i.e. the
netpoll path actually preforms all the needed work no the device, and the call
to net_rx_action winds up doing nothing, except removing the napi_struct from
the poll_list.  However I think this is probably a small price to pay, given
that the alternative is a crash.

This patch fixes minor annoyance during transmission of unsolicited
neighbor advertisements from userspace to multicast addresses (as
far as I can see in RFC, this is allowed and the similar functionality
for IPv4 has been in arping for a long time).

Outgoing multicast packets get reinserted into local processing as if they
are received from the network. The machine thus sees its own NA and fills
the logs with error messages. This patch removes the message if NA has been
generated locally.

This patch addresses a book-keeping issue in tcp_vegas.c.  At present
tcp_vegas does separate book-keeping of cwnd based on packet sequence
numbers.  A mismatch can develop between this book-keeping and
tp->snd_cwnd due, for example, to delayed acks acking multiple
packets.  When vegas transitions to reno operation (e.g. following
loss), then this mismatch leads to incorrect behaviour (akin to a cwnd
backoff).  This seems mostly to affect operation at low cwnds where
delayed acking can lead to a significant fraction of cwnd being
covered by a single ack, leading to the book-keeping mismatch.  This
patch modifies the congestion avoidance update to avoid the need for
separate book-keeping while leaving vegas congestion avoidance
functionally unchanged.  A secondary advantage of this modification is
that the use of fixed-point (via V_PARAM_SHIFT) and 64 bit arithmetic
is no longer necessary, simplifying the code.

Some example test measurements with the patched code (confirming no functional
change in the congestion avoidance algorithm) can be seen at:

As reported by Hermann Lauer, PCS PHY support in the sungem
driver simply doesn't work.

When the chip is reset due to open, or some other similar operation,
the PCS is reset too but we don't program it back into a running
state.  The result is no link when the device is brought up.

This partially rectifies the situation for the moment, by kicking
the PCS after a sungem chip reset so that it will renegotiate and
be re-enabled again.

The behavior is still a little bit dodgy as the added renegotiate
make the link take some time after bringing the interface up,
but this is a significant improvement in that things actually work
now :-)

Based almost entirely upon an initial patch by Hermann.

Under my 2.6.28-rc6 sparc64, when associating to an AP through my
zd1211rw device, I was seeing kernel log messages like (not exact output):

  Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw]

For the zd1211rw module, on RX, the 80211 packet will be located after
the PLCP header in the skb data buffer. The PLCP header being 5 bytes
long, the 80211 header will start unaligned from an aligned skb
buffer.

As per Documentation/unaligned-memory-access.txt, we must replace the
not unaligned() safe compare_ether_addr() with memcmp() to protect
architectures that require alignment.

After fixing zd1211rw: use unaligned safe memcmp() in-place of
compare_ether_addr(), I started to see kernel log messages detailing
unaligned access:

  Kernel unaligned access at TPC[100f7f44] sta_info_get+0x24/0x68 [mac80211]

As with the aforementioned patch, the unaligned access was eminating
from a compare_ether_addr() call. Concerned that whilst it was safe to
assume that unalignment was the norm for the zd1211rw, and take
preventative measures, it may not be the case or acceptable to use the
easy fix of changing the call to memcmp().

My research however indicated that it was OK to do this, as there are
a few instances where memcmp() is the preferred mechanism for doing
mac address comparisons throughout the module.

"netif_carrier_{on,off}() handles starting and stopping packet flow into

ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state.
But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't

This patch fixes a bug in tcp_vegas.c.  At the moment this code leaves
ssthresh untouched.  However, this means that the vegas congestion
control algorithm is effectively unable to reduce cwnd below the
ssthresh value (if the vegas update lowers the cwnd below ssthresh,
then slow start is activated to raise it back up).  One example where
this matters is when during slow start cwnd overshoots the link
capacity and a flow then exits slow start with ssthresh set to a value
above where congestion avoidance would like to adjust it.

I should have noticed this earlier... :-) The previous solution
to URG+GSO/TSO will cause SACK block tcp_fragment to do zig-zig
patterns, or even worse, a steep downward slope into packet
counting because each skb pcount would be truncated to pcount
of 2 and then the following fragments of the later portion would
restore the window again.

Basically this reverts "tcp: Do not use TSO/GSO when there is
urgent data" (33cf71ce). It also removes some unnecessary code
from tcp_current_mss that didn't work as intented either (could
be that something was changed down the road, or it might have
been broken since the dawn of time) because it only works once
urg is already written while this bug shows up starting from
~64k before the urg point.

The retransmissions already are split to mss sized chunks, so
only new data sending paths need splitting in case they have
a segment otherwise suitable for gso/tso. The actually check
can be improved to be more narrow but since this is late -rc
already, I'll postpone thinking the more fine-grained things.

On "/etc/init.d/capiutils stop", this oops happened.

The oops happens on reading /proc/capi/controllers because
capi_ctrl->procinfo is called for the wrongly not unregistered
controller, which points to b1isa_procinfo(), which was removed on
module unload.

b1isa_exit() did not call b1isa_remove() for its controllers because
io[0] == 0 on module unload despite having been 0x340 on module load.

Besides, just removing the controllers that where added on module
load time and not those that were added later via b1isa_add_card() is
wrong too - the place where all added cards are found is isa_dev[].

Due to a wrong safety check in af_can.c it was not possible to filter
for SFF frames with a specific CAN identifier without getting the
same selected CAN identifier from a received EFF frame also.

This fix has a minimum (but user visible) impact on the CAN filter
API and therefore the CAN version is set to a new date.

Indeed the 'old' API is still working as-is. But when now setting
CAN_(EFF|RTR)_FLAG in can_filter.can_mask you might get less traffic
than before - but still the stuff that you expected to get for your

The bnx2 chips do not support per MSI vector masking.  On 5706/5708, new MSI
address/data are stored only when the MSI enable bit is toggled.  As a result,
SMP affinity no longer works in the latest kernel.  A more serious problem is
that the driver will no longer receive interrupts when the MSI receiving CPU
goes offline.

The workaround in this patch only addresses the problem of CPU going offline.
When that happens, the driver's timer function will detect that it is making
no forward progress on pending interrupt events and will recover from it.

Eric Dumazet reported the problem.

We also found that if an interrupt is internally asserted while MSI and INTA
are disabled, the chip will end up in the same state after MSI is re-enabled.
The same workaround is needed for this problem.

This fixes the MN10300 kernel module linking to match the toolchain.  RELA
relocs don't use the value at the location being relocated.  This has been
working because the tools always leave the value at the target location
cleared.

If xpc.ko and gru.ko are both statically linked into the kernel, then
xpc_init() can get called before gru_init() and make a call to one of the
gru's exported functions before the gru has initialized itself. The end
result is a NULL dereference.

In the CONFIG_SMP case the irq_choose_cpu() code was returning back
a logical cpu id not the physical id.  We were writing that directly
into the HW register.

We need to be calling get_hard_smp_processor_id() so irq_choose_cpu()
always returns a physical cpu id.

Count the insertion of new pages in the statistics used to drive the
pageout scanning code.  This should help the kernel quickly evict
streaming file IO.

We count on the fact that new file pages start on the inactive file LRU
and new anonymous pages start on the active anon list.  This means
streaming file IO will increment the recent scanned file statistic, while
leaving the recent rotated file statistic alone, driving pageout scanning
to the file LRUs.

Pageout activity does its own list manipulation.
