[SCSI] scsi_error: fix target reset handling
There's a target reset bug.
This loop:
for (id = 0; id <= shost->max_id; id++) {
Never terminates if shost->max_id is set to ~0, like aic94xx does.
It's also pretty inefficient since you mostly have compact target
numbers, but the max_id can be very high. The best way would be to
sort the recovery list by target id and skip them if they're equal,
but even a worst case O(N^2) traversal is probably OK here, so fix it
by finding the next highest target number (assuming n+1) and
terminating when there isn't one.

There is no loss of connectivity at that time and the driver thinks
that it would be fast to retry at the driver level. SCSI-ml will however

This will then cause dm-multipath to fail the path and possibley switch

We also were fast failing device errors to dm multiapth when

[SCSI] block: separate failfast into multiple bits.
Multipath is best at handling transport errors. If it gets a device
error then there is not much the multipath layer can do. It will just
access the same device but from a different path.
This patch breaks up failfast into device, transport and driver errors.
The multipath layers (md and dm mutlipath) only ask the lower levels to
fast fail transport errors. The user of failfast, read ahead, will ask
to fast fail on all errors.
Note that blk_noretry_request will return true if any failfast bit
is set. This allows drivers that do not support the multipath failfast
bits to continue to fail on any failfast error like before. Drivers
like scsi that are able to fail fast specific errors can check
for the specific fail fast type. In the next patch I will convert

[SCSI] scsi: add transport host byte errors (v3)
Currently, if there is a transport problem the iscsi drivers will return
outstanding commands (commands being exeucted by the driver/fw/hw) with
DID_BUS_BUSY and block the session so no new commands can be queued.
Commands that are caught between the failure handling and blocking are
failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values.
When the recovery_timeout fires, the iscsi drivers then fail IO with
DID_NO_CONNECT.
For fcp, some drivers will fail some outstanding IO (disk but possibly not
tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry
and hits the scsi_error.c failfast check, block the rport, and commands
caught in the race are failed with DID_IMM_RETRY. Other drivers, may
hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk
to be called.
The following patches attempt to unify what upper layers will see drivers
like multipath can make a good guess. This relies on drivers being
hooked into their transport class.
This first patch just defines two new host byte errors so drivers can
return the same value for when a rport/session is blocked and for
when the fast_io_fail_tmo fires.
The idea is that if the LLD/class detects a problem and is going to block
a rport/session, then if the LLD wants or must return the command to scsi-ml,
then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue
the IO into the same scsi queue it came from, until the fast io fail timer
fires and the class decides what to do.
When using multipath and the fast_io_fail_tmo fires then the class
can fail commands with DID_TRANSPORT_FAILFAST or drivers can use
DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or
the equivlent in iscsi if we ever implement more advanced recovery methods.
A LLD, like lpfc, could continue to return DID_ERROR and then it will hit
the normal failfast path, so drivers do not have fully be ported to
work better. The point of the patches is that upper layers will
not see a failure that could be recovered from while the rport/session is
blocked until fast_io_fail_tmo/recovery_timeout fires.

[SCSI] fc class: unblock target after calling terminate callback (take 2)
When we block a rport and the driver implements the terminate
callback we will fail IO that was running quickly. However
IO that was in the scsi_device/block queue sits there until
the dev_loss_tmo fires, and this can make it look like IO is
lost because new IO will get executed but that IO stuck in
the blocked queue sits there for some time longer.
With this patch when the fast io fail tmo fires, we will
fail the blocked IO and any new IO. This patch also allows
all drivers to partially support the fast io fail tmo. If the
terminate io callback is not implemented, we will still fail blocked
IO and any new IO, so multipath can handle that.
This patch also allows the fc and iscsi classes to implement the
same behavior. The timers are just unfornately named differently.
This patch also fixes the problem where drivers were unblocking
the target in their terminate callback, which was needed for
rport removal, but for fast io fail timeout it would cause
IO to bounce arround the scsi/block layer and the LLD queuecommand.
And it for drivers that could have IO stuck but did not have
a terminate callback the unblock calls in the class will fix
them.

[SCSI] Add helper code so transport classes/driver can control queueing (v3)
SCSI-ml manages the queueing limits for the device and host, but
does not do so at the target level. However something something similar
can come in userful when a driver is transitioning a transport object to
the the blocked state, becuase at that time we do not want to queue
io and we do not want the queuecommand to be called again.
The patch adds code similar to the exisiting SCSI_ML_*BUSY handlers.
You can now return SCSI_MLQUEUE_TARGET_BUSY when we hit
a transport level queueing issue like the hw cannot allocate some
resource at the iscsi session/connection level, or the target has temporarily
closed or shrunk the queueing window, or if we are transitioning
to the blocked state.
bnx2i, when they rework their firmware according to netdev
developers requests, will also need to be able to limit queueing at this
level. bnx2i will hook into libiscsi, but will allocate a scsi host per
netdevice/hba, so unlike pure software iscsi/iser which is allocating
a host per session, it cannot set the scsi_host->can_queue and return
SCSI_MLQUEUE_HOST_BUSY to reflect queueing limits on the transport.
The iscsi class/driver can also set a scsi_target->can_queue value which
reflects the max commands the driver/class can support. For iscsi this
reflects the number of commands we can support for each session due to
session/connection hw limits, driver limits, and to also reflect the
session/targets's queueing window.
Changes:
v1 - initial patch.
v2 - Fix scsi_run_queue handling of multiple blocked targets.
Previously we would break from the main loop if a device was added back on
the starved list. We now run over the list and check if any target is
blocked.

Fix RTC wakealarm sysfs interface breakage.
Commit
ed458df4d2470adc02762a87a9ad665d0b1a2bd4 ("PnP: move
pnpacpi/pnpbios_init to after PCI init") moved the PnP RTC discovery
later, and now the ACPI RTC glue code doesn't find it any more, breaking
the RTC wakealarm sysfs interfaces, as reported by Rafael.
This really is fairly messy, and we have several annoying ordering
constraints here - the PnP code that sets up the RTC resources wants to
run after the PCI resources have to be registered, which in turn needs
to run after ACPI has at least enumerated the root PCI buses etc. Our
initcall ordering is not fine-grained enough to make this all painless.
So this moves the ACPI RTC glue ("acpi_rtc_init()") down to a regular
module call, which fixes the problem Rafael has. The reason this isn't
wonderful is that we really should do acpi_rtc_init before we do the
rtc_cmos init, and now those two are in the same module_init() section.
Which happens to work, but only because drivers/rtc is linked after
drivers/acpi. In other words, we still have a very subtle ordering
issue here. Grr.

If an external PHY is found the driver falls through to the default
case in the switch and overwrites the PHY ID. Add the missing break.

e1000: allow VLAN devices to use TSO and CSUM offload
This patch changes e1000 to set vlan_features so TSO and CSUM
offload can be used by VLAN devices, similar as with the other
Intel drivers.

ipvs: Add proper dependencies on IP_VS, and fix description header line.
Linus noted a build failure case:
net/netfilter/ipvs/ip_vs_xmit.c: In function 'ip_vs_tunnel_xmit':
net/netfilter/ipvs/ip_vs_xmit.c:616: error: implicit declaration of function 'ip_select_ident'
The proper include file (net/ip.h) is being included in ip_vs_xmit.c to get
that declaration. So the only possible case where this can happen is if
CONFIG_INET is not enabled.
This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS
entry.
Also, while we're here, remove the out of date "EXPERIMENTAL" string in the
IP_VS config help header line. IP_VS no longer depends upon CONFIG_EXPERIMENTAL
