#1711641 — [PATCH 4.12 36/65] staging: comedi: comedi_fops: do not call blocking ops when !TASK_RUNNING

Subject[PATCH 4.12 36/65] staging: comedi: comedi_fops: do not call blocking ops when !TASK_RUNNING
Message-ID<ueyQc-39h-69@gated-at.bofh.it>
In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ian Abbott <abbotti@mev.co.uk>

commit cef988642cdac44e910a27cb6e8166c96f86a0df upstream.

Comedi's read and write file operation handlers (`comedi_read()` and
`comedi_write()`) currently call `copy_to_user()` or `copy_from_user()`
whilst in the `TASK_INTERRUPTIBLE` state, which falls foul of the
`might_fault()` checks when enabled.  Fix it by setting the current task
state back to `TASK_RUNNING` a bit earlier before calling these
functions.

Subject[PATCH 4.12 62/65] MIPS: DEC: Fix an int-handler.S CPU_DADDI_WORKAROUNDS regression

In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maciej W. Rozycki <macro@linux-mips.org>

commit 68fe55680d0f3342969f49412fceabb90bdfadba upstream.

Fix a commit 3021773c7c3e ("MIPS: DEC: Avoid la pseudo-instruction in
delay slots") regression and remove assembly errors:

arch/mips/dec/int-handler.S: Assembler messages:
arch/mips/dec/int-handler.S:162: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:163: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:229: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:230: Error: Macro used $at after ".set noat"

triggering with with the CPU_DADDI_WORKAROUNDS option set and the DADDIU
instruction.  This is because with that option in place the instruction
becomes a macro, which expands to an LI/DADDU (or actually ADDIU/DADDU)
sequence that uses $at as a temporary register.

With CPU_DADDI_WORKAROUNDS we only support `-msym32' compilation though,
and this is already enforced in arch/mips/Makefile, so choose the 32-bit
expansion variant for the supported configurations and then replace the
64-bit variant with #error just in case.

From: Christoph Hellwig <hch@lst.de>

commit 8a9d6e964d318533ba3d2901ce153ba317c99a89 upstream.

The blocklayout code does not compile cleanly for a 32-bit sector_t,
and also has no reliable checks for devices sizes, which makes it
unsafe to use with a kernel that doesn't support large block devices.

From: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com>

commit a7b8829d242b1a58107e9c02b09e93aec446d55c upstream.

Add SPI Serial Interface Mode (SIM) register information
in st_sensor_settings look up table to support devices
(like LSM303AGR accel sensor) that allow just SPI-3wire
communication mode. SIM mode has to be configured before any
other operation since it is not enabled by default and the driver
is not able to read without that configuration

Whilst a fairly substantial patch, the actual logic is simple and it
is better to have the generic fix than a band aid.

In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bin Liu <b-liu@ti.com>

commit 2eac13624364db5b5e1666ae0bb3a4d36bc56b6e upstream.

While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.

Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.

This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

commit 3aa0907675a38498d8f2d343e94207ad28a117cf upstream.

PMECC caps extraction from old DT bindings is broken, thus leading to
erroneous EL registers offset, which in turn make HW ECC unusable on
sama5d2 when old bindings are in use.

Passing the NAND dev node instead of the NFC node to of_match_node()
solves the problem.

#1711648 — [PATCH 4.12 58/65] pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD20

FromGreg Kroah-Hartman <gregkh@linuxfoundation.org>
Date2017-08-15 03:30 +0200
Subject[PATCH 4.12 58/65] pinctrl: uniphier: fix WARN_ON() of pingroups dump on LD20
Message-ID<ueyQc-39h-75@gated-at.bofh.it>
In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@socionext.com>

commit 1bd303dc04c3f744474e77c153575087b657f7e1 upstream.

The pingroups dump of debugfs hits WARN_ON() in pinctrl_groups_show().
Filling non-existing ports with '-1' turned out a bad idea.

Fixes: 336306ee1f2d ("pinctrl: uniphier: add UniPhier PH1-LD20 pinctrl driver")

#1711649 — [PATCH 4.12 30/65] iio: aspeed-adc: wait for initial sequence.

FromGreg Kroah-Hartman <gregkh@linuxfoundation.org>
Date2017-08-15 03:30 +0200
Subject[PATCH 4.12 30/65] iio: aspeed-adc: wait for initial sequence.
Message-ID<ueyQd-39h-85@gated-at.bofh.it>
In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mykola Kostenok <c_mykolak@mellanox.com>

commit 737cc2a593782df6846b3cab7e0f64384f58364a upstream.

This patch enables adc engine at initialization time and waits
for the initial sequence completion before enabling adc channels.

Without this code adc channels are not functional and shows
zeros for all connected channels.

Tested on mellanox msn platform.

v1 -> v2:
Pointed by Rick Altherr:
 - Wait init sequence code enabled by bool
from OF match table.

#1711653 — [PATCH 4.12 03/65] futex: Remove unnecessary warning from get_futex_key

FromGreg Kroah-Hartman <gregkh@linuxfoundation.org>
Date2017-08-15 03:40 +0200
Subject[PATCH 4.12 03/65] futex: Remove unnecessary warning from get_futex_key
Message-ID<ueyZP-3cJ-7@gated-at.bofh.it>
In reply to#1711640
4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mel Gorman <mgorman@suse.de>

commit 48fb6f4db940e92cfb16cd878cddd59ea6120d06 upstream.

Commit 65d8fc777f6d ("futex: Remove requirement for lock_page() in
get_futex_key()") removed an unnecessary lock_page() with the
side-effect that page->mapping needed to be treated very carefully.

Two defensive warnings were added in case any assumption was missed and
the first warning assumed a correct application would not alter a
mapping backing a futex key.  Since merging, it has not triggered for
any unexpected case but Mark Rutland reported the following bug
triggering due to the first warning.

  kernel BUG at kernel/futex.c:679!
  Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
  Modules linked in:
  CPU: 0 PID: 3695 Comm: syz-executor1 Not tainted 4.13.0-rc3-00020-g307fec773ba3 #3
  Hardware name: linux,dummy-virt (DT)
  task: ffff80001e271780 task.stack: ffff000010908000
  PC is at get_futex_key+0x6a4/0xcf0 kernel/futex.c:679
  LR is at get_futex_key+0x6a4/0xcf0 kernel/futex.c:679
  pc : [<ffff00000821ac14>] lr : [<ffff00000821ac14>] pstate: 80000145

The fact that it's a bug instead of a warning was due to an unrelated
arm64 problem, but the warning itself triggered because the underlying
mapping changed.

This is an application issue but from a kernel perspective it's a
recoverable situation and the warning is unnecessary so this patch
removes the warning.  The warning may potentially be triggered with the
following test program from Mark although it may be necessary to adjust
NR_FUTEX_THREADS to be a value smaller than the number of CPUs in the
system.

            futex_wrapper(mem, FUTEX_CMP_REQUEUE_PI, 1, NULL, mem + 4, 1);
        }
    }

    int main(int argc, char *argv[])
    {
        int i;

        mem = mmap(NULL, MEM_SIZE, MEM_PROT,
               MAP_SHARED | MAP_ANONYMOUS, -1, 0);

        printf("Mapping @ %p\n", mem);

        printf("Creating futex threads...\n");

        for (i = 0; i < NR_FUTEX_THREADS; i++)
            pthread_create(&threads[i], NULL, poll_futex, NULL);

        printf("Flipping mapping...\n");

The bio describing discard operation is allocated by
__blkdev_issue_discard() which returns us a reference to it. That
reference is never released and thus we leak this bio. Drop the bio
reference once it completes in xlog_discard_endio().

The problem is that shmem_unused_huge_shrink() moves entries from the
global sbinfo->shrinklist to its local lists and then releases the
spinlock.  However, a parallel shmem_setattr() could access one of these
entries directly and add it back to the global shrinklist if it is
removed, with the spinlock held.

The logic itself looks solid since an entry could be either in a local
list or the global list, otherwise it is removed from one of them by
list_del_init().  So probably the race condition is that, one CPU is in
the middle of INIT_LIST_HEAD() but the other CPU calls list_empty()
which returns true too early then the following list_add_tail() sees a
corrupted entry.

list_empty_careful() is designed to fix this situation.

At least the Acer Iconia Tab8 / aka W1-810 uses 1MiHz instead of
1MHz for one of its busses, fix this up to 1MHz instead of failing
the probe of that bus.

This fixes the accelerometer on the Acer Iconia Tab8 not working.

commit 5279fc7724ae3a82c9cfe5b09c1fb07ff0e41056 upstream.

bdw_load_gamma_lut is writing beyond the array to the maximum value.
The intend of the function is to clamp values > 1 to 1, so write
the intended color to the max register.

This fixes the following KASAN warning:
