queuecommand() looked at the remote and local node IDs before it read
the bus generation. The corresponding race with sbp2_reconnect updating
these data was probably impossible to happen though because the current
code blocks the SCSI layer during reconnection. However, better safe

the SCSI layer.

1. We don't need to round the SBP-2 segment size limit down to a
multiple of 4 kB (0xffff -> 0xf000). It is only necessary to
ensure quadlet alignment (0xffff -> 0xfffc).
2. Use dma_set_max_seg_size() to tell the DMA mapping infrastructure
and the block IO layer about the restriction. This way we can
remove the size checks and segment splitting in the queuecommand
path.
This assumes that no other code in the firewire stack uses
dma_map_sg() with conflicting requirements. It furthermore assumes
that the controller device's platform actually allows us to set the
segment size to our liking. Assert the latter with a BUG_ON().
3. Also use blk_queue_max_segment_size() to tell the block IO layer
about it. It cannot know it because our scsi_add_host() does not
point to the FireWire controller's device.

firewire: Preserve response data alignment bug when it is harmless
Recently, a bug having to do with the alignment of transaction response
data was fixed. However, some apps such as libdc1394 relied on the
presence of that bug in order to function correctly. In order to stay
compatible with old versions of those apps, this patch preserves the bug
in cases where it is harmless to normal operation (such as the single
quadlet read) due to a simple duplication of data. This guarantees
maximum compatability for those users who are using the old app with the
fixed kernel.

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER
architecture does:
This enables us to cleanly fix the Calgary IOMMU issue that some devices
are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423).
I think that per-device dma_mapping_ops support would be also helpful for
KVM people to support PCI passthrough but Andi thinks that this makes it
difficult to support the PCI passthrough (see the above thread). So I
CC'ed this to KVM camp. Comments are appreciated.
A pointer to dma_mapping_ops to struct dev_archdata is added. If the
pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's
NULL, the system-wide dma_ops pointer is used as before.
If it's useful for KVM people, I plan to implement a mechanism to register
a hook called when a new pci (or dma capable) device is created (it works
with hot plugging). It enables IOMMUs to set up an appropriate
dma_mapping_ops per device.
The major obstacle is that dma_mapping_error doesn't take a pointer to the
device unlike other DMA operations. So x86 can't have dma_mapping_ops per
device. Note all the POWER IOMMUs use the same dma_mapping_error function
so this is not a problem for POWER but x86 IOMMUs use different
dma_mapping_error functions.
The first patch adds the device argument to dma_mapping_error. The patch
is trivial but large since it touches lots of drivers and dma-mapping.h in
all the architecture.
This patch:
dma_mapping_error() doesn't take a pointer to the device unlike other DMA
operations. So we can't have dma_mapping_ops per device.
Note that POWER already has dma_mapping_ops per device but all the POWER
IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device
argument.

Use only statically allocated data for PHY config packet transmission.
With the previous incarnation, some data wouldn't be freed if the packet
transmit callback was never called.
A theoretical drawback now is that, in PCs with more than one card,
card A may complete() for a waiter on card B. But this is highly
unlikely and its impact not serious. Bus manager B may reset bus B
before the PHY config went out, but the next phy config on B should be
fine. However, with a timeout of 100ms, this situation is close to
impossible.

Isochronous reception in dualbuffer mode is reportedly broken with
TI TSB43AB22A on x86-64. Descriptor addresses above 2G have been
determined as the trigger:
https://bugzilla.redhat.com/show_bug.cgi?id=435550
Two fixes are possible:
- pci_set_consistent_dma_mask(pdev, DMA_31BIT_MASK);
at least when IR descriptors are allocated, or
- simply don't use dualbuffer.
This fix implements the latter workaround.
But we keep using dualbuffer on x86-32 which won't give us highmen (and
thus physical addresses outside the 31bit range) in coherent DMA memory
allocations. Right now we could for example also whitelist PPC32, but
DMA mapping implementation details are expected to change there.

In theory, card->flush_timer could already access a transaction between
fw_send_request()'s spin_unlock_irqrestore and the rest of what happens
in fw_send_request(). This would happen if the process which sends the
request is preempted and put to sleep right after spin_unlock_irqrestore
for longer than 100ms.
Therefore we fill in everything in struct fw_transaction at which the
flush_timer might look at before we lift the lock.
To do: Ensure that the timer does not pick up the transaction before
the time of the AT request event plus split transaction timeout.
Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
Reported by Jay Fenlason: A bus reset tasklet may call
fw_flush_transactions and touch transactions (call their callback which
will free them) while the context which submitted the transaction is
still inserting it into the transmission queue.
A simple solution to this problem is to _not_ "flush" the transactions
because of a bus reset (complete the transcations as 'cancelled'). They
will now simply time out (completed as 'cancelled' by the split-timeout
timer).
Jay Fenlason thought of this fix too but I was quicker to type it out.
:-)
Background:
Contexts which access an instance of struct fw_transaction are:
1. the submitter, until it inserted the packet which is embedded in the
transaction into the AT req DMA,
2. the AsReqTrContext tasklet when the request packet was acked by the
responder node or transmission to the responder failed,
3. the AsRspRcvContext tasklet when it found a request which matched
an incoming response,
4. the card->flush_timer when it picks up timed-out transactions to
cancel them,
5. the bus reset tasklet when it cancels transactions (this access is
eliminated by this patch),
6. a process which shuts down an fw_card (unregisters it from fw-core
when the controller is unbound from fw-ohci) --- although in this
case there shouldn't really be any transactions anymore because we
wait until all card users finished their business with the card.
All of these contexts run concurrently (except for the 6th, presumably).
The 1st is safe against the 2nd and 3rd because of the way how a request
packet is carefully submitted to the hardware. A race between 2nd and
3rd has been fixed a while ago (bug 9617). The 4th is almost safe
against 1st, 2nd, 3rd; there are issues with it if huge scheduling
latencies occur, to be fixed separately. The 5th looks safe against
2nd, 3rd, and 4th but is unsafe against 1st. Maybe this could be fixed
with an explicit state variable in struct fw_transaction. But this
would require fw_transaction to be rewritten as only dynamically
allocatable object with reference counting --- not a good solution if we
also can simply kill this 5th accessing context (replace it by the 4th).

This is a functionally equivalent replacement of the current reference
counting of struct fw_card instances. It only converts it to common
idioms as suggested by Kristian Høgsberg:

If the low-level driver failed to initialize a card properly without
noticing it, fw-core was blocked indefinitely when trying to send a

up keyboard input.
https://bugzilla.redhat.com/show_bug.cgi?id=444694https://bugzilla.redhat.com/show_bug.cgi?id=446763
This problem was introduced between 2.6.25 and 2.6.26-rc1 by commit
2a0a259049 "firewire: wait until PHY
configuration packet was transmitted (fix bus reset loop)".
The solution is to wait with timeout. I tested it with 7 different
working controllers and 1 non-working controller. On the working ones,
the packet callback complete()s usually --- but not always --- before a
timeout of 10ms. Hence I chose a safer timeout of 100ms.
On the few tests with the non-working controller ALi M5271, PHY config
packet transmission always timed out so far. (Fw-ohci needs to be fixed
for this controller independently of this deadline fix. Often the core
doesn't even attempt to send a phy config because not even self ID
reception works.)

Callers of fill_bus_reset_event() have to take card->lock. Otherwise
access to node data may oops if node removal is in progress.
A lockless alternative would be
- event->local_node_id = card->local_node->node_id;
+ tmp = fw_node_get(card->local_node);
+ event->local_node_id = tmp->node_id;
+ fw_node_put(tmp);
and ditto with the other node pointers which fill_bus_reset_event()
accesses. But I went the locked route because one of the two callers
already holds the lock. As a bonus, we don't need the memory barrier

If userspace ignores the POLLERR bit from poll(), and only attempts to

This is an unnecessary duplication and copy of request's

- Lots of drivers still use MAX_COMMAND_SIZE. So I have left
that #define but equate it to BLK_MAX_CDB. The way I see it
and is reflected in the patch below is.
MAX_COMMAND_SIZE - means: The longest fixed-length (*) SCSI CDB

BLK_MAX_CDB. - The allocated space at the request level
- I have audit all ISA drivers and made sure none use ->cmnd in a DMA

(*)fixed-length here means commands that their size can be determined
by their opcode and the CDB does not carry a length specifier, (unlike
the VARIABLE_LENGTH_CMD(0x7f) command). This is actually not exactly
true and the SCSI standard also defines extended commands and
vendor specific commands that can be bigger than 16 bytes. The kernel
will support these using the same infrastructure used for VARLEN CDB's.
So in effect MAX_COMMAND_SIZE means the maximum size command
scsi-ml supports without specifying a cmd_len by ULD's

When a device changes its configuration ROM, it announces this with a

and whether any unit directories went away or were added on this node.
Tested with an IOI FWB-IDE01AB which has its link-on bit set if bus
power is available but does not respond to ROM read requests if self
power is off. This implements
- recognition of the units if self power is switched on after fw-core
gave up the initial attempt to read the config ROM,
- shutdown of the units when self power is switched off.
Also tested with a second PC running Linux/ieee1394. When the eth1394

Unlike the ohci1394 driver, fw-ohci uses the selfIDGeneration field of
bus reset packets to determine the generation of incoming requests as
per OHCI 1.1 clause 8.4.2.3. This is more precise --- provided that the
controller inserts the correct generation. Texas Instruments chips
often don't.
This prevented the transmission of response packets, which for example
broke AV/C transactions as used when communicating with miniDV cameras
and any other AV/C devices.
There is apparently no way to detect and adjust incorrect generations.
Therefore we ignore the generation of bus reset packets from TI chips
and use the generation of the self ID buffer instead. Alas this is
received at a slightly wrong time. In rare cases, this could cause us
to not respond to legitimate requests or to respond to expired requests.
(The latter is less likely because the bus reset packet AR event is
typically handled before the self ID complete event.)
Bug reported by Mladen Kuntner, who was extraordinarily patient while
dealing with the driver maintainers. Fix confirmed to be required and
