If session is NULL, it is not possible to access its name field. So I
have split apart the printing of the error message to drop the
printing of the name field in this case.
The macro PRINTK actually only evaluates its arguments starting with
the third one if the bitwise conjunction of the first two is non-zero.
Normally, this conjunction would only be non-zero if debugging mode
were turned on, but when session is NULL, the first argument in both
the old and new code is -1, and thus the bitwise conjunction is true.
Perhaps a different strategy is desired, such as using tunnel->debug,
which session->debug is initialized to, but tunnel can also be NULL,
so this does not completely solve the problem.
This problem was found using the following semantic match

The following patch fixes a bug in the iscsi nop processing.
The target sends iscsi nops to ping the initiator and the
initiator has to send nops to reply and can send nops to
ping the target.
In 2.6.25 we moved the nop processing to the kernel to handle
problems when the userspace daemon is not up, but the target
is pinging us, and to handle when scsi commands timeout, but
the transport may be the cause (we can send a nop to check
the transport). When we added this code we added a bug where
if the transport timer wakes at the exact same time we are supposed to check
for a nop timeout we drop the session instead of checking the transport.
This patch checks if a iscsi ping is outstanding and if the ping has
timed out, to determine if we need to signal a connection problem.

This message appears on modprobe/rmmod/modprobe of the driver. It's
caused because if the driver has no instances, it returns an error
from gdth_init, which causes the module to fail to load.
Unfortunately, the module's pci driver is still registered at this
point.
Fix this by making gdth behave like a modern driver and insert even if
it doesn't find any instances (in case of hot plug or software driven
binding).

The global timer handling is problematic in that if someone unbinds a

As noticed by Ben Greear, macvlan crashes the kernel when unloading the
module. The reason is that it tries to clean up the macvlan_port pointer
on the macvlan device itself instead of the underlying device. A non-NULL
pointer is taken as indication that the macvlan_handle_frame_hook is
valid, when receiving the next packet on the underlying device it tries
to call the NULL hook and crashes.

What's fixed:
in ipath_cancel_sends()
We need to unconditionally set ABORTING. So, swap the tests
so the set_bit() isn't shadowed by the &&.
If we've disarmed the piobufs, then we need to unconditionally
set DISARMED. So, move it out from the overly protective if
at the bottom.
in sdma_abort_task()
Abort_task was written knowing that the SDMA engine would always
be reset (and restarted) on error. A recent change broke that
fundamental assumption by taking the restart portion and making
it conditional on a link status change. But, SDMA can go boom

Now that we always use PIO for vl15 on 7220, we could get stuck forever

fewer kernel buffers than the existing threshold.
Clean up the initialization a bit to get ordering safer and more
sensible, and use the existing ipath_chg_kernavail call to do init,
rather than doing it separately.
Drop unnecessary clearing of pio buffer on pio parity error.
Drop incorrect updating of pioavailshadow when exitting freeze mode
(software state may not match chip state if buffer has been allocated

Currently, iw_cxgb3 is severely limited on the amount of userspace
memory that can be registered in in a single memory region, which
causes big problems for applications that expect to be able to
register 100s of MB.
The problem is that the driver uses a single kmalloc()ed buffer to
hold the physical buffer list (PBL) for the entire memory region
during registration, which means that 8 bytes of contiguous memory are
required for each page of memory being registered. For example, a 64
MB registration will require 128 KB of contiguous memory with 4 KB
pages, and it unlikely that such an allocation will succeed on a busy
system.
This is purely a driver problem: the temporary page list buffer is not
needed by the hardware, so we can fix this by writing the PBL to the
hardware in page-sized chunks rather than all at once. We do this by
splitting the memory registration operation up into several steps:
- Allocate PBL space in adapter memory for the full registration
- Copy PBL to adapter memory in chunks
- Allocate STag and enable memory region
This also allows several other cleanups to the __cxio_tpt_op()
interface and related parts of the driver.
This change leaves the reregister memory region and memory window
operations broken, but they already didn't work due to other
longstanding bugs, so fixing them will be left to a later patch.

Current iw_cxgb3 code adds PBL memory to the driver's gen_pool in 2 MB
chunks. This limits the largest single allocation that can be done to
the same size, which means that with 4 KB pages, each of which takes 8
bytes of PBL memory, the largest memory region that can be allocated
is 1 GB (256K PBL entries * 4 KB/entry).
Remove this limit by adding all the PBL memory in a single gen_pool
chunk, if possible. Add code that falls back to smaller chunks if
gen_pool_add() fails, which can happen if there is not sufficient
contiguous lowmem for the internal gen_pool bitmap.

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577
I was unable to access a computer containing an Intel EtherExpress 16 network
card using IPv6.
I traced this to failure of neighbour discovery. When I used an "ip -6 neigh
add" command, on the computer attempting access, to insert a binding between
the IPv6 address of the computer with the Intel EtherExpress 16 network card
and the card's ethernet address, I was able to access that computer using
IPv6.
Neighbour discovery requires working multicast. The driver sources file
eexpress.c contains an approximately 30 line function eexp_setup_filter used
when loading multicast addresses.
I found 3 problems in this function
1) It wrote the number of multicast addresses to the card instead of the
number of bytes in the multicast addresses.
2) When loading multiple multicast addresses it loaded the first one
provided multiple times instead of loading each one once.
3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the
test for the error situation of 'dmi' being NULL.
Correcting these problems allows the computer with the Intel EtherExpress 16
network card to found by IPv6 neighbour discovery.
p.s. There is some information on the Intel EtherExpress 16 at

This patch adds support for the BM PHY, a new PHY model being used
on ICH9-based implementations.
This new PHY exposes issues in the ICH9 silicon when receiving
jumbo frames large enough to use more than a certain part of the
Rx FIFO, and this unfortunately breaks packet split jumbo receives.
For this reason we re-introduce (for affected adapters only) the
jumbo single-skb receive routine back so that people who do
wish to use jumbo frames on these ich9 platforms can do so.
Part of this problem has to do with CPU sleep states and to make
sure that all the wake up timings are correctly we force them
with the recently merged pm_qos infrastructure written by Mark
Gross. (See http://lkml.org/lkml/2007/10/4/400).

The sysfs layer has an internal protection, that ensures, that
all the process sitting inside ->sore/->show callback exits
before the appropriate entry is unregistered (the calltraces
are rather big, but I can provide them if required).
On the other hand, bonding takes rtnl_lock in
a) the bonding_store_bonds, i.e. in ->store callback,
b) module exit before calling the sysfs unregister routines.
Thus, the classical AB-BA deadlock may occur. To reproduce run
# while :; do modprobe bonding; rmmod bonding; done
and
# while :; do echo '+bond%d' > /sys/class/net/bonding_masters ; done
in parallel.
The fix is to move the bond_destroy_sysfs out of the rtnl_lock,
but _before_ bond_free_all to make sure no bonding devices exist
after module unload.

A couple of distributions (Fedora, Ubuntu) were having weird problems with the
ATI IXP series PATA controllers being reported as simplex. At the heart of
the problem is that both distros ignored the recommendations to load pata_acpi
and ata_generic *AFTER* specific host drivers.
The underlying cause however is that if you D3 and then D0 an ATI IXP it
helpfully throws away some configuration and won't let you rewrite it.
Add checks to ata_generic and pata_acpi to pin ATIIXP devices. Possibly the
real answer here is to quirk them and pin them, but right now we can't do that
before they've been pcim_enable()'d by a driver.

* LBA48 now works as long as it uses DMA (LBA48 devices still aren't
allowed as it can destroy data if PIO is used for any reason).
* No need to mask IRQs for read DMAs as IDMA_DONE is properly raised
after transfer to memory is actually completed. There will be some
spurious interrupts but host_intr will handle it correctly and
manipulating port IRQ mask interacts badly with the other port for
some reason, so command type dependent port IRQ masking is not used
anymore.

inic162x can't reliably read back TF or at least we don't know how to
do it yet. The only values which seem reliable are status and error.
This patch updates access to TF.
* implement inic_tf_read() which reads the TF area in mmio area
* implement custom inic_qc_fill_rtf() which only returns true if
status indicates device error. it'll be returning bogus addresses
for device errors but it'll be able to report why it failed at
least.
* implement custom inic_check_ready() and use ata_wait_after_reset()
instead of the SFF version.
* use inic_tf_read() for classification.
This is not perfect but it fixes hotplug detection failure and at
least makes the driver report 0's instead of random garbages while
reporting valid status and error for device errors.

Convert sata_mv's EH for FIS-based switching (FBS) over to the
sequence recommended by Marvell. This enables us to catch/analyze
multiple failed links on a port-multiplier when using NCQ.
To do this, we clear the ERR_DEV bit in the EDMA Halt-Conditions register,
so that the EDMA engine doesn't self-disable on the first NCQ error.
Our EH code sets the MV_PP_FLAG_DELAYED_EH flag to prevent new commands
being queued while we await completion of all outstanding NCQ commands
on all links of the failed PM.
The SATA Test Control register tells us which links have failed,
so we must only wait for any other active links to finish up
before we stop the EDMA and run the .error_handler afterward.
The patch also includes skeleton code for handling of non-NCQ FBS operation.
This is more for documentation purposes right now, as that mode is not yet
enabled in sata_mv.

Introduce a new "delayed error handling" mechanism in sata_mv,
to enable us to eventually deal with multiple simultaneous NCQ
failures on a single host link when a PM is present.
This involves a port flag (MV_PP_FLAG_DELAYED_EH) to prevent new
commands being queued, and a pmp bitmap to indicate which pmp links
had NCQ errors.
The new mv_pmp_error_handler() uses those values to invoke
ata_eh_analyze_ncq_error() on each failed link, prior to freezing
the port and passing control to sata_pmp_error_handler().
This is based upon a strategy suggested by Tejun.
For now, we just implement the delayed mechanism.
The next patch in this series will add the multiple-NCQ EH code
to take advantage of it.

Fix things so that libata-eh can attempt a READ_LOG_EXT_10H

Some controllers (jmb and inic162x) use 0x77 and 0x7f to indicate that
the device isn't ready yet. It looks like they use 0xff if device
presence is detected but connection isn't established. 0x77 or 0x7f
after connection is established and use the value from signature FIS
after receiving it.
This patch implements ata_check_ready(), which takes TF status value
and determines whether the port is ready or not considering the above
and other conditions, and use it in @check_ready() functions. This is
safe as both 0x77 and 0x7f aren't valid ready status value even though
they have BSY bit cleared.
This fixes hot plug detection failures which can be triggered with
certain drives if they aren't already spun up when the data connector
is hot plugged.

while generally most users will have PNP enabled, drivers can support
non-PNP build mode too - and most drivers implement it. That is typically
done by providing a dummy pnp_driver structure that will not probe anything.
The fallback routines in the driver will handle this dumber mode of

This patch implements that. I have not tested whether this actually
works on real hardware so take care. It does resolve the build bug.

The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing.
The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem.
