During discussions with Mike Christie, I became convinced that we needed
a larger vendor id. This patch extends the id from 32 to 64 bits.
This applies on top of the prior patches that add SCSI transport events
via netlink.

events
This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2
The patch has been updated to optimize the send path, per the discussions
in the initial posting.
Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.
This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
single and shared definitions for the SCSI Transport. It is tied into the
base SCSI subsystem intialization.
Contains a single interface routine, scsi_send_transport_event(), for a
transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
messages
- Adds 3 new routines to the fc transport:
fc_get_event_number() - to get a FC event #
fc_host_post_event() - to send a simple FC event (32 bits of data)
fc_host_post_vendor_event() - to send a Vendor unique event, with
arbitrary amounts of data.
Note: the separation of event number allows for a LLD to send a standard
event, followed by vendor-specific data for the event.
Note: This patch assumes 2 prior fc transport patches have been installed:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2
http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2
Sorry - next time I'll do something like making these individual
patches of the same posting when I know they'll be posted closely
together.

Add Promise SuperTrak 'stex' driver, supporting SuperTrak
EX8350/8300/16350/16300 controllers. The controller's firmware accepts
SCSI commands, handing them to the underlying RAID or JBOD disks.
The driver consisted of the following cleanups and fixes, beyond its
initial submission:
Ed Lin:
stex: cleanup and minor fixes
stex: add new device ids
stex: update internal copy code path
stex: add hard reset function
stex: adjust command timeout in slave_config routine
stex: use more efficient method for unload/shutdown flush
Jeff Garzik:
[SCSI] Add Promise SuperTrak 'shasta' driver.
Rename drivers/scsi/shasta.c to stex.c ("SuperTrak EX").
[SCSI] stex: update with community comments from 'Promise SuperTrak' thread
[SCSI] stex: Fix warning, trim trailing whitespace.
[SCSI] stex: remove last remnants of "shasta" project code name
[SCSI] stex: removed 6-byte command emulation
[SCSI] stex: minor cleanups
[SCSI] stex: minor fixes: irq flag, error return value
[SCSI] stex: use dma_alloc_coherent()

We currently allocated seperate tfms for data and header digests. There
is no reason for this since we can never calculate a rx header and
digest at the same time. Same for sends. So this patch removes the data
tfms and has the send and recv sides use the rx_tfm or tx_tfm.
I also made the connection creation code preallocate the tfms because I
thought I hit a bug where I changed the digests settings during a
relogin but could not allocate the tfm and then we just failed.

iscsi_tcp calculates padding by using the expected transfer length. This
has the problem where if we have immediate data = no and initial R2T =
yes, and the transfer length ended up needing padding then we send:
1. header
2. padding which should have gone after data
3. data
Besides this bug, we also assume the target will always ask for nice
transfer lengths and the first burst length will always be a nice value.
As far as I can tell form the RFC this is not a requirement. It would be
silly to do this, but if someone did it we will end doing bad things.
Finally the last bug in that bit of code is in our handling of the
recalculation of data digests when we do not send a whole iscsi_buf in
one try. The bug here is that we call crypto_digest_final on a
iscsi_sendpage error, then when we send the rest of the iscsi_buf, we
doiscsi_data_digest_init and this causes the previous data digest to be
lost.
And to make matters worse, some of these bugs are replicated over and
over and over again for immediate data, solicited data and unsolicited
data. So the attached patch made over the iscsi git tree (see
kernel.org/git for details) which I updated today to include the patches
I said I merged, consolidates the sending of data, padding and digests
and calculation of data digests and fixes the above bugs.

A couple targets like string bean and MDS, send r2ts with
a data len greater than the max burst we agreed to. We
were being strict in our enforcing of the iscsi rfc in that
code path, but there is no driver limitation that prevents
us from fullfilling the request. To allow those targets
to work we will ignore the max_burst length and send as
much data as the target asks for assuming it has consciously
decided to override its max burst length.

It is possible that a ctask could be completing and getting
cleaned up at the same time, we are finishing up the last
data transfer. This could then result in the data transfer
code using stale or invalid values. This patch adds a refcount
to the ctask. When the count goes to zero then we know the
transmit thread and recv thread or softirq are not touching
it and we can safely release it.
The eh should not need to grab a reference because it only cleans
up a task if it has both the xmit mutex and recv lock (or recv
side suspended).

iSCSI RFC states that the first burst length must be smaller than the
max burst length. We currently assume targets will be good, but that may
not be the case, so this patch adds a check.

do not have to track it.

Sanitize the Vendor, Product, and Revision strings contained in an
INQUIRY result by setting all non-graphic or non-ASCII characters to ' '.
Since the standard disallows such characters, this will affect
only non-compliant devices.
To help maintain backward compatibility, NUL characters are treated
specially. They are taken as string terminators; they and all the
following characters are set to ' '. If some valid characters get
erased as a result... well, we weren't seeing them before so we haven't
lost anything.
The primary purpose of this change is to allow blacklist entries to
match devices with illegal Vendor or Product strings.
In addition, the patch updates a couple of function prototypes, giving
inq_result its correct type (unsigned char *).

The fix isn't actually in sd: it's in scsi_device_get(). I modified it
to allow devices to be returned in SDEV_CANCEL, but not SDEV_DEL. This
means that the device_remove_driver, which occurs in device_del() in
scsi_remove_device() after the device has gone into SDEV_CANCEL is now
effective at flushing the cache.

This patch sets can_queue in the aic94xx driver's scsi_host to better
performing values than what's there currently. It seems that
asd_ha->seq.can_queue reflects the number of requests that can be
queued per controller; so long as there's one scsi_host per
controller, it seems logical that the scsi_host ought to have the same
can_queue value. To the best of my (still limited) knowledge, this
method provides the correct value.
The effect of leaving this value set to 1 is terrible performance in
the case of either (a) certain Maxtor SAS drives flying solo or (b)
flooding several disks with I/O simultaneously (md-raid). There may be
more scenarios where we see similar problems that I haven't uncovered.

This flag denotes local attachment of the phy. There are two problems
with it:
1) It's actually redundant ... you can get the same information simply
by seeing whether a host is the phys parent
2) we condition a lot of phy parameters on it on the false assumption
that we can only control local phys. I'm wiring up phy resets in the
aic94xx now, and it will be able to reset non-local phys as well.
I fixed 2) by moving the local check into the reset and stats function
of the mptsas, since that seems to be the only HBA that can't
(currently) control non-local phys.

Unlike the other tty comment patch this one has code changes. Specifically
it limits the queue size for a tty to 64K characters (128Kbytes) worst case
even if the tty is ignoring tty->throttle. This is because certain drivers

safeguard anyway.

If we
- shut down a clean array,
- restart with one (or more) drive(s) missing
- make some changes
- pause, so that they array gets marked 'clean',
the event count on the superblock of included drives
will be the same as that of the removed drives.
So adding the removed drive back in will cause it
to be included with no resync.
To avoid this, we only update the eventcount backwards when the array
is not degraded. In this case there can (should) be no non-connected
drives that we can get confused with, and this is the particular case
where updating-backwards is valuable.

When reading /dev/vcsa while a font with more than 256 characters is
loaded, one of the attribute bits records the 9th bit of the character.
But depending on the console driver (vgacon or fbcon for instance), that's
bit 3 or bit 0. And there is no way for userland to know that, thus no way
for userland to safely grab the screen content. So here is a (tested)
patch:
Add a VT_GETHIFONTMASK ioctl for knowing which bit is the 9th bit for VC
text (vc_hi_font_mask field of the vc_data structure).

I wish I was happier about this patch. It'll serve as a placeholder for
the moment. I'm still trying to get a G550 working in order to even
reproduce the problem this patch introduces. I find that the G450 has
jitter even without this patch, so it won't show me what the patch changed.
At this point, I'll continue trying to get the G550 to work, and in
parallel work with the G450 to work out the kinks.
The patch is below.
Set XDVICLKCTRL only on PPC, as doing this apparently introduces jitter on

While testing Moxa C218T/PCI on PowerPC 405EP I found that loading firmware
using the linux kernel driver fails because calculation of the checksum is
not endianess independent in the original code.
After I fixed this I found that uploading firmware in a system with
multiple cards causes a kernel oops. I had a look in the recent moxa
sources and found that they do some kind of locking there. Applying this
lock fixed the problem.
Alan sayeth:
Checksum changes are clearly correct. Other changes is an improvement but
not I think enough to handle malicious firmware attacks. That said such an
attacker has CAP_SYS_RAWIO anyway so that part is irrelevant except for
neatness.

On an nForce4-equipped machine with two SATA disk in raid1 setup using dmraid,
we experienced frequent deadlock of the system under high i/o load. 'cat
/dev/zero > ~/zero' was the most reliable way to reproduce them: Randomly
after a few GB, 'cp' would be left in 'D' state along with kjournald and
kmirrord. The functions cp and kjournald were blocked in did vary, but
kmirrord's wchan always pointed to 'mempool_alloc()'. We've seen this pattern
on 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates
that this problem has been around even before.
So much for the facts, here's my interpretation: mempool_alloc() first tries
to atomically allocate the requested memory, or falls back to hand out
preallocated chunks from the mempool. If both fail, it puts the calling
process (kmirrord in this case) on a private waitqueue until somebody refills
the pool. Where the only 'somebody' is kmirrord itself, so we have a
deadlock.
I worked around this problem by falling back to a (blocking) kmalloc when
before kmirrord would have ended up on the waitqueue. This defeats part of
the benefits of using the mempool, but at least keeps the system running. And
it could be done with a two-line change. Note that mempool_alloc() clears the
GFP_NOIO flag internally, and only uses it to decide whether to wait or return
an error if immediate allocation fails, so the attached patch doesn't change
behaviour in the non-deadlocking case. Path is against current git
(2.6.18-rc4), but should apply to earlier versions as well. I've tested on
2.6.15, where this patch makes the difference between random lockup and a
stable system.

respond to the initialization sequence. Perhaps the sequence needs to
be updated, or perhaps something else can be done. For now, this patch
(as764) restricts the range to include only the revision mentioned in
the original comment.
This resolves (for now!) Bugzilla entry #6950.

This patch removes support for a clone of Nokia DKU-5 cable made by Ours
Technology Inc, as it turned out that the cable does not use the pl2303
chip, but OTI-6858 chip which is not compatible with the pl2303.

Here is a patch against the CPCI hotplug core to fix up PCI resource
assignment such that things will actually work when a hot inserted
device is enabled. I mentioned this patch to you way back in April at
ELC, but am only now out from under things enough to clean it up and
submit it. I've basically cribbed the corresponding code from
shpchp_pci.c, so there are no big surprises. If it's still possible, I
wouldn't mind this going into 2.6.18, but it wouldn't be the end of the
world if it went into 2.6.19.
