Revert "ext4: allow readdir()'s of large empty directories to be interrupted"
This reverts commit
1028b55bafb7611dda1d8fed2aeca16a436b7dff.
It's broken: it makes ext4 return an error at an invalid point, causing
the readdir wrappers to write the the position of the last successful
directory entry into the position field, which means that the next
readdir will now return that last successful entry _again_.
You can only return fatal errors (that terminate the readdir directory
walk) from within the filesystem readdir functions, the "normal" errors
(that happen when the readdir buffer fills up, for example) happen in
the iterorator where we know the position of the actual failing entry.
I do have a very different patch that does the "signal_pending()"
handling inside the iterator function where it is allowable, but while
that one passes all the sanity checks, I screwed up something like four
times while emailing it out, so I'm not going to commit it today.
So my track record is not good enough, and the stars will have to align
better before that one gets committed. And it would be good to get some
review too, of course, since celestial alignments are always an iffy
debugging model.
IOW, let's just revert the commit that caused the problem for now.

- Defer GPIO device setup until after gpiolib is initialized.

drivers initialize so early (befor core_initcall()) so that the
gpiolib isn't even initialized itself. That limits what the
library can do, and we cannot reference uninitialized fields until
later.
Defer some of the initialization until right after the gpiolib is
initialized in these (rare) cases.
- As a consequence: do not use devm_* resources when allocating the
states in the initial set-up of the gpiochip.

- In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.

parisc: Unbreak handling exceptions from kernel modules
Handling exceptions from modules never worked on parisc.
It was just masked by the fact that exceptions from modules
don't happen during normal use.
When a module triggers an exception in get_user() we need to load the
main kernel dp value before accessing the exception_data structure, and
afterwards restore the original dp value of the module on exit.

find_outdev calls inet{,6}_fib_lookup_dev() or dev_get_by_index() to

returns error pointer and dev_get_by_index() returns NULL. But the function

gpio: pxa: fix legacy non pinctrl aware builds
In legacy pxa builds, ie. non device-tree and platform-data only builds,
pinctrl is not yet available. As a consequence, the pinctrl gpio
direction change function is a stub, returning always success.
In the current state, the gpio driver direction function believes the
pinctrl direction change was successful, and exits without actually
changing the gpio direction.
This patch changes the logic :
- if the pinctrl direction function fails, gpio direction will report
that failure
- if the pinctrl direction function succeeds, gpio direction is changed
by the gpio driver anyway.
This is sub optimal in the pinctrl aware case, as the gpio direction
will be changed twice: once by pinctrl function and another time by
the gpio direction function.
Yet it should be acceptable in this form, as this is functional for all
pxa platforms (device-tree and platform-data), and moreover changing a
gpio direction is very very seldom, usually in machine initialization,
seldom in drivers probe, and an exception for ac97 reset bug.

gpio / ACPI: ignore GpioInt() GPIOs when requesting GPIO_OUT_*
When firmware does not use _DSD properties that allow properly name GPIO
resources, the kernel falls back on parsing _CRS resources, and will
return entries described as GpioInt() as general purpose GPIOs even
though they are meant to be used simply as interrupt sources for the
device:
Device (ETSA)
{
Name (_HID, "ELAN0001")
...
Method(_CRS, 0x0, NotSerialized)
{
Name(BUF0,ResourceTemplate ()
{
I2CSerialBus(
0x10, /* SlaveAddress */
ControllerInitiated, /* SlaveMode */
400000, /* ConnectionSpeed */
AddressingMode7Bit, /* AddressingMode */
"\\_SB.I2C1", /* ResourceSource */
)
GpioInt (Edge, ActiveLow, ExclusiveAndWake, PullNone,,
"\\_SB.GPSW") { BOARD_TOUCH_GPIO_INDEX }
} )
Return (BUF0)
}
...
}
This gives troubles with drivers such as Elan Touchscreen driver
(elants_i2c) that uses devm_gpiod_get to look up "reset" GPIO line and
decide whether the driver is responsible for powering up and resetting
the device, or firmware is. In the above case the lookup succeeds, we
map GPIO as output and later fail to request client->irq interrupt that
is mapped to the same GPIO.
Let's ignore resources described as GpioInt() while parsing _CRS when
requesting output GPIOs (but allow them when requesting GPIOD_ASIS or
GPIOD_IN as some drivers, such as i2c-hid, do request GPIO as input and
then map it to interrupt with gpiod_to_irq).

It's easiest if we just pass in an adjusted resource range rather than
deriving it from the passed in namespace. With the resource range

libnvdimm, pfn: fix uuid validation
If we detect a namespace has a stale info block in the init path, we
should overwrite with the latest configuration. In fact, we already
return -ENODEV when the parent uuid is invalid, the same should be done
for the 'self' uuid. Otherwise we can get into a condition where
userspace is unable to reconfigure the pfn-device without directly /
manually invalidating the info block.

ipv6: Count in extension headers in skb->network_header
When sending a UDPv6 message longer than MTU, account for the length
of fragmentable IPv6 extension headers in skb->network_header offset.
Same as we do in alloc_new_skb path in __ip6_append_data().
This ensures that later on __ip6_make_skb() will make space in
headroom for fragmentable extension headers:
/* move skb->data to ip header from ext header */
if (skb->data < skb_network_header(skb))
__skb_pull(skb, skb_network_offset(skb));
Prevents a splat due to skb_under_panic:
skbuff: skb_under_panic: text:

Revert "ib_srpt: Convert to percpu_ida tag allocation"
This reverts commit
0fd10721fe3664f7549e74af9d28a509c9a68719.
That patch causes the ib_srpt driver to crash as soon as the first SCSI
command is received:
kernel BUG at drivers/infiniband/ulp/srpt/ib_srpt.c:1439!
invalid opcode: 0000 [#1] SMP
Workqueue: target_completion target_complete_ok_work [target_core_mod]
RIP: srpt_queue_response+0x437/0x4a0 [ib_srpt]
Call Trace:
srpt_queue_data_in+0x9/0x10 [ib_srpt]
target_complete_ok_work+0x152/0x2b0 [target_core_mod]
process_one_work+0x197/0x480
worker_thread+0x49/0x490
kthread+0xea/0x100
ret_from_fork+0x22/0x40
Aside from the crash, the shortcomings of that patch are as follows:
- It makes the ib_srpt driver use I/O contexts allocated by
transport_alloc_session_tags() but it does not initialize these I/O
contexts properly. All the initializations performed by
srpt_alloc_ioctx() are skipped.
- It swaps the order of the send ioctx allocation and the transition to
RTR mode which is wrong.
- The amount of memory that is needed for I/O contexts is doubled.
- srpt_rdma_ch.free_list is no longer used but is not removed.
