On a 64-bit architecture, if ib_umem_get() is called with a size value
that is so big that npages is negative when cast to int, then the
length of the page list passed to get_user_pages(), namely
min_t(int, npages, PAGE_SIZE / sizeof (struct page *))
will be negative, and get_user_pages() will immediately return 0 (at
least since 900cf086, "Be more robust about bad arguments in
get_user_pages()"). This leads to an infinite loop in ib_umem_get(),
since the code boils down to:
while (npages) {
ret = get_user_pages(...);
npages -= ret;
}
Fix this by taking the minimum as unsigned longs, so that the value of
npages is never truncated.
The impact of this bug isn't too severe, since the value of npages is
checked against RLIMIT_MEMLOCK, so a process would need to have an
astronomical limit or have CAP_IPC_LOCK to be able to trigger this,
and such a process could already cause lots of mischief. But it does
let buggy userspace code cause a kernel lock-up; for example I hit
this with code that passes a negative value into a memory registartion
function where it is promoted to a huge u64 value.

Packet sending is driven by two flags, tx_ready and tx_queued.
It was possible, that there were queued data for sending and
hardware was flagged as blocked but in fact it was not.
The tx_queued was indicator but should be really a counter else
first fragmented packet resets tx_queued flag, but there may be
pending packets which do not get sent.
New semantics:
tx_ready - set, if hw is ready to send packet, no packet is being
transferred right now
set the flag right at the place where data are copied
into hw memory and not earlier without checking if it
was succesful
tx_queued - count of enqueued packets, including fragments

I made a change to u-boot that used the FP (Fractional Part) field of BRGR
to achieve more accurate baud rate generation. Unfortunately, the
atmel_serial driver looks at the whole BRGR register when trying to detect
the baud rate that the port is currently running at, so setting FP to a
nonzero value breaks the baud rate detection.
I'll sit on the u-boot patch for a while longer, but this is clearly a
bug in the atmel_serial driver which should be fixed.

During the initial array synchronization process there is a window between
when a prexor operation is scheduled to a specific stripe and when it
completes for a sync_request to be scheduled to the same stripe. When
this happens the prexor completes and the stripe is unconditionally marked
"insync", effectively canceling the sync_request for the stripe. Prior to
2.6.23 this was not a problem because the prexor operation was done under
sh->lock. The effect in older kernels being that the prexor would still
erroneously mark the stripe "insync", but sync_request would be held off
and re-mark the stripe as "!in_sync".
Change the write completion logic to not mark the stripe "in_sync" if a
prexor was performed. The effect of the change is to sometimes not set
STRIPE_INSYNC. The worst this can do is cause the resync to stall waiting
for STRIPE_INSYNC to be set. If this were happening, then STRIPE_SYNCING
would be set and handle_issuing_new_read_requests would cause all
available blocks to eventually be read, at which point prexor would never
be used on that stripe any more and STRIPE_INSYNC would eventually be set.
echo repair > /sys/block/mdN/md/sync_action will correct arrays that may
have lost this race.

- Use class_{create,destroy} not class_{register,unregister}.
- Use device_{create,destroy} not device_{register,unregister}.
- Free the per-device data only when TWO conditions are true:
* Driver is unbound from underlying SPI device, and
* Device is no longer open (new)
Also, spi_{get,set}_drvdata not dev_{get,set}_drvdata for simpler code.

the reason is another kconfig tool bug that has to be worked around in
the driver's Kconfig file: if FW_LOADER is selected in a second
dependency, that is not properly propagated up the dependencies.
in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028:
config MEDIA_TUNER_XC2028
tristate "XCeive xc2028/xc3028 tuners"
depends on VIDEO_MEDIA && I2C
depends on HOTPLUG
select FW_LOADER
which got selected by MEDIA_TUNER:
config MEDIA_TUNER
tristate
default VIDEO_MEDIA && I2C
depends on VIDEO_MEDIA && I2C
select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG
but the kconfig tool did not pick up this second-order dependency and
allowed CONFIG_FW_LOADER=m to be selected - in which case the build
fails.
the workaround i found was to move the select of FW_LOADER one level up,
so that the buggy kconfig tool can notice it and can act appropriately.
This problem can probably be worked around in other ways as well, i went
for the minimal fix.
Obviously, the kconfig tool should be fixed, it is not reasonable to
expect driver authors to do manual dependency resolution (that kconfig
itself already does) and uglify the Kconfig files. The kconfig tool did
nothing to warn about this situation and did not prevent this faulty
.config from being constructed.

Some problems have been experienced in the field which cause an oops
in the pppol2tp driver if L2TP tunnels fail while passing data.
The pppol2tp driver uses private data that is referenced via the
sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes
sure that the driver uses sock_hold() when it holds a reference to the
sk pointer. This affects its sendmsg(), recvmsg(), getname(),
[gs]etsockopt() and ioctl() handlers.
Tested by ISP where problem was seen. System has been up 10 days with
no oops since running this patch. Without the patch, an oops would
occur every 1-2 days.

If an L2TP daemon closes a tunnel socket while packets are queued in
the tunnel's reorder queue, a kernel warning is logged because the
socket is closed while skbs are still referencing it. The fix is to
purge the queue in the socket's release handler.

If there are no networks on the free list, expire the oldest one when
creating a new adhoc network. Because ipw2200 and the ieee80211 stack

Commit 64e9159f5d ("serial_core:
uart_set_ldisc infrastructure") introduced the ability for low-level
serial drivers to be informed when the tty ldisc changes.
However, the actual tty-layer function that does this callback for
serial devices was declared with the wrong type, having a spurious and
unused 'ldisc' argument.
This fixed the resulting compiler warning by just removing it.

- Make ata_sff_altstatus private so nobody uses it by mistake
- Drop the 400nS delay from it
Add
ata_sff_irq_status - encapsulates the IRQ check logic
This function keeps the existing behaviour for altstatus using devices. I
actually suspect the logic was wrong before the changes but -rc isn't the
time to play with that
ata_sff_sync - ensure writes hit the device
Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so
that we can fix the nasty delay this causes on most systems.
- ata_sff_pause - 400nS delay
Ensure the command hit the device and delay 400nS
- ata_sff_dma_pause
Ensure the I/O hit the device and enforce an HDMA1:0 transition delay.
Requires altstatus register exists, BUG if not so we don't risk
corruption in MWDMA modes. (UDMA the checksum will save your backside in
theory)
The only other complication then is devices with their own handlers.
rb532 can use dma_pause but scc needs to access its own altstatus
register for internal errata workarounds so directly call the drivers own
altstatus function.

* Differentiate between bay devices in dock stations and others:
- When an ACPI_NOTIFY_EJECT_REQUEST appears, just signal uevent to
userspace (that is when the optional eject button on a bay device is
pressed/pulled) giving the possibility to unmount file systems and to
clean up. Also, only send uevent in case we get an EJECT_REQUEST
without doing anything else. In other cases, you'll get an add/remove
event because libata attaches/detaches the device.
- In case of a dock event, which in turn signals an
ACPI_NOTIFY_EJECT_REQUEST, immediately detach the device, because it
may already have been gone
* In case of an ACPI_NOTIFY_DEVICE/BUS_CHECK, evaluate _STA to check if
the device has been plugged or unplugged. If plugged, hotplug it, if
unplugged, just signal event to userspace

The tty layer provides a callback that is used when the line discipline
is changed. Some hardware uses this to configure hardware specific
features such as IrDA mode on serial ports. Unfortunately the serial
layer does not provide this feature or pass it down to drivers.
Blackfin used to hack around this by rewriting the tty ops, but those are
now properly shared and const so the hack fails. Instead provide the
proper operations.
This change plus a follow up from the Blackfin guys is needed to avoid
blackfin losing features in this release.

Both the PNP/PCI conflict detection quirk and the PNP system

I think it's best to keep the resource and to keep the type bit
(IORESOURCE_MEM, etc), so that we match the list from firmware
as closely as possible.

When using 4+ GB RAM and SWIOTLB is active, the driver corrupts
memory by writing an skb after the relevant DMA page has been
unmapped. Although this doesn't happen when *not* using bounce
buffers, clearing the pointer to the DMA page after unmapping
it fixes the problem.

If we fail to transmit a packet, we assume the queue is full and put

xmit it, we loop, and the result can be transmitting the same skb twice.
