PAUSE frames are only relevant for the real device, broadcasting them
to all macvlan devices can cause a significant load increase.

We should only tell the hardware its capable of DMA'ing
to us only what we asked dev_alloc_skb(). Prior to this
it is possible a large RX'd frame could have corrupted
DMA data but for us but we were saved only because we
were previously also pci_map_single()'ing the same large
value. The issue prior to this though was we were unmapping
a smaller amount which the prior DMA patch fixed.

This should fix the SW-IOMMU bounce buffer starvation
seen ok kernel.org bugzilla 11811:
http://bugzilla.kernel.org/show_bug.cgi?id=11811
Users on MacBook Pro 3.1/MacBook v2 would see something like:
DMA: Out of SW-IOMMU space for 4224 bytes at device 0000:0b:00.0
Unfortunately its only easy to trigger on MacBook Pro 3.1/MacBook v2
so far so its difficult to debug (even with swiotlb=force).
We were pci_unmap_single()'ing less bytes than what we called
for with pci_map_single() and as such we were starving
the swiotlb from its 64MB amount of bounce buffers. We remain
consistent and now always use sc->rxbufsize for RX. While at
it we update the beacon DMA maps as well to only use the data
portion of the skb, previous to this we were pci_map_single()'ing
more data for beaconing than what we tell the hardware it can use,
therefore pushing more iotlb abuse.
Still not sure why this is so easily triggerable on
MacBook Pro 3.1, it may be the hardware configuration
tends to use more memory > 3GB mark for DMA.

I asked around, and he's right, there may be platforms that do not allow
passing such such an address to the DMA API functions. This patch
changes it by using the proper dma_sync_single_range_for_cpu API
invented for this purpose.

PHY is mostly compatible with the existing VSC8244 PHY. The init sequence
is different and the interrupt mask lacks some bits present in the VSC8244.
Rather than making a copy of the existing VSC234x config_intr function and
change one constant, I modify it to select the interrupt mask based on
which driver is calling it. This lets it be used by both drivers.

Since changeset e79ad711a0108475c1b3a03815527e7237020b08 from mainline,
>From David S. Miller,
empty packet can be transmitted on connected socket for datagram protocols.
However, this patch broke a high level application using ROSE network protocol with connected datagram.
Bulletin Board Stations perform bulletins forwarding between BBS stations via ROSE network using a forward protocol.
Now, if for some reason, a buffer in the application software happens to be empty at a specific moment,
ROSE sends an empty packet via unfiltered packet socket.
When received, this ROSE packet introduces perturbations of data exchange of BBS forwarding,
for the application message forwarding protocol is waiting for something else.
We agree that a more careful programming of the application protocol would avoid this situation and we are
willing to debug it.
But, as an empty frame is no use and does not have any meaning for ROSE protocol,
we may consider filtering zero length data both when sending and receiving socket data.
The proposed patch repaired BBS data exchange through ROSE network that were broken since 2.6.22.11 kernel.

As GRE tries to call the update_pmtu function on skb->dst and
bridge supplies an skb->dst that has a NULL ops field, all is
not well.
This patch fixes this by giving the bridge device an ops field
with an update_pmtu function. For the moment I've left all
other fields blank but we can fill them in later should the
need arise.
Based on report and patch by Philip Craig.

Conntrack creation through ctnetlink has two races:
- the timer may expire and free the conntrack concurrently, causing an
invalid memory access when attempting to put it in the hash tables
- an identical conntrack entry may be created in the packet processing
path in the time between the lookup and hash insertion
Hold the conntrack lock between the lookup and insertion to avoid this.

This patch fixes http://bugzilla.kernel.org/show_bug.cgi?id=12014
Since most (if not all) implementations of TSO and even the in-kernel
software GSO do not update the urgent pointer when splitting a large
segment, it is necessary to turn off TSO/GSO for all outgoing traffic
with the URG pointer set.
Looking at tcp_current_mss (and the preceding comment) I even think
this was the original intention. However, this approach is insufficient,
because TSO/GSO is turned off only for newly created frames, not for
frames which were already pending at the arrival of a message with
MSG_OOB set. These frames were created when TSO/GSO was enabled,
so they may be large, and they will have the urgent pointer set
in tcp_transmit_skb().
With this patch, such large packets will be fragmented again before
going to the transmit routine.
As a side note, at least the following NICs are known to screw up
the urgent pointer in the TCP header when doing TSO:
Intel 82566MM (PCI ID 8086:1049)
Intel 82566DC (PCI ID 8086:104b)
Intel 82541GI (PCI ID 8086:1076)

Hi,
after noticing that my Netgear FA411 (PCMCIA-NIC) [1] stopped working with
the release of the 2.6.25 kernel (sidux-version), I checked the
respective driver sources and noticed that the pcnet_cs driver bailed
out with "use axnet_cs instead" for the Netgear FA411, but axnet_cs
doesn't claim this ID.
I compiled a kernel with the PCMCIA-ID for the netgear card moved to
axnet_cs from pcnet_cs which worked. I then contacted sidux-kernel
maintainer Stefan Lippers-Hollmann who turned the info into this patch
and integrated it into the kernel:
<http://svn.berlios.de/svnroot/repos/fullstory/linux-sidux-2.6/trunk/debian/patches/features/2.6.27.4_PCMCIA_move-PCMCIA-ID-for-Netgear-FA411-from-pcnet_cs-to-axnet_cs.patch>
This works for me and AFAIK there were no reports of any breakage for
other devices on sidux-support.
This looks like a trivial patch, but since I have very limited
experience with kernel modifications I might be woefully wrong there.
But if there are no side effects of this patch, is it possible to get it
into the official kernel?
I can provide more detailed information on the affected hardware if
necessary.

Don't overflow the 16-character fb_fix_screeninfo id string (fixes some
console erasing and blanking artifacts). Have the ID default to "Unknown"
on machines with no built-in video and no nubus devices. Check for
fb_alloc_cmap failure.

It seems that on some nVidia controllers using AltStatus register
can be unreliable so default to Status register if the PCI device
is in Compatibility Mode. In order to achieve this:
* Add ide_pci_is_in_compatibility_mode() inline helper to <linux/ide.h>.
* Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host
driver for nVidia controllers in Compatibility Mode.
* Teach actual_try_to_identify() and drive_is_ready() about the new flag.
This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ
config option in 2.6.25 and using AltStatus register unconditionally when
available (kernel.org bugs #11659 and #10216).
[ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people
and distributions use) it never worked correctly. ]
Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

scsi_eh_try_stu() was still using the timeout parameter in the device
which is now not set (i.e. zero filled) meaning that it waited no time
at all for the start unit command to complete (leading the routine to
conclude failure every time). This lead to a 2.6.27 regression:
http://bugzilla.kernel.org/show_bug.cgi?id=12120
Where firewire devices that were non spec compliant wouldn't spin up.
Fix this by using the block queue timeout value instead.

The zfcp_scsi_queuecommand was not acting according to the standard
when the respective unit was not available. In this case an -EBUSY was
returned, which is not valid in itself, and in addition scsi_done
was called. This combination is not allowed and was leading to a
double finish of the request and therefor double decrement of the
host_busy counter.

Waiting for the ERP to be finished in a task running in the global
kernel work-queue is a bad idea, especially if the ERP needs to run
another job in this work-queue before it can finish. -> deadlock.
This patch removes the necessity to wait for a finished ERP from the
scan task and moves the job scheduling to the end of the ERP.

The check of having a valid pointer was performed before the
processing was secured by the lock. Between those two steps the
pointer can turn invalid. During further processing another value is
used (referenced by the pointer described above) as a function pointer
which is never verified to be valid either, resulting under some
circumstances in an invalid function call. This patch is fixing both
issues.

Aborting a SCSI cmnd might requrie to send a abort_fsf_cmnd. If the
creation of this fsf_req fails an ERR_PTR is returned where a NULL
value would be expected as an error indicator. This ERR_PTR is
dereferenced as valid fsf_req in succeeding processing leading to
an error.
