Rasmus Villemoes acbbe6fbb2 kcmp: fix standard comparison bug
The C operator <= defines a perfectly fine total ordering on the set of
values representable in a long.  However, unlike its namesake in the
integers, it is not translation invariant, meaning that we do not have
"b <= c" iff "a+b <= a+c" for all a,b,c.

This means that it is always wrong to try to boil down the relationship
between two longs to a question about the sign of their difference,
because the resulting relation [a LEQ b iff a-b <= 0] is neither
anti-symmetric or transitive.  The former is due to -LONG_MIN==LONG_MIN
(take any two a,b with a-b = LONG_MIN; then a LEQ b and b LEQ a, but a !=
b).  The latter can either be seen observing that x LEQ x+1 for all x,
implying x LEQ x+1 LEQ x+2 ...  LEQ x-1 LEQ x; or more directly with the
simple example a=LONG_MIN, b=0, c=1, for which a-b < 0, b-c < 0, but a-c >
0.

Note that it makes absolutely no difference that a transmogrying bijection
has been applied before the comparison is done.  In fact, had the
obfuscation not been done, one could probably not observe the bug
(assuming all values being compared always lie in one half of the address
space, the mathematical value of a-b is always representable in a long).
As it stands, one can easily obtain three file descriptors exhibiting the
non-transitivity of kcmp().

Side note 1: I can't see that ensuring the MSB of the multiplier is
set serves any purpose other than obfuscating the obfuscating code.

Stas Sergeev caac7e6d00 sh: get_user_pages_fast() must flush cache
This patch avoids fuse hangs on sh4 by flushing the cache on
get_user_pages_fast().  This is not necessary a good thing to do, but
get_user_pages() does this, so get_user_pages_fast() should too.

Please note the patch for mips arch that addresses the similar problem:
  https://kernel.googlesource.com/pub/scm/linux/kernel/git/ralf/linux/+/linux-3.4.50%5E!/#F0

They basically simply disable get_user_pages_fast() at all, using a
fall-back to get_user_pages().  But my fix is different, it adds an
explicit cache flushes.

Nicolas Iooss c680e41b3a eventpoll: fix uninitialized variable in epoll_ctl
When calling epoll_ctl with operation EPOLL_CTL_DEL, structure epds is
not initialized but ep_take_care_of_epollwakeup reads its event field.
When this unintialized field has EPOLLWAKEUP bit set, a capability check
is done for CAP_BLOCK_SUSPEND in ep_take_care_of_epollwakeup.  This
produces unexpected messages in the audit log, such as (on a system
running SELinux):

    type=AVC msg=audit(1408212798.866:410): avc:  denied
    { block_suspend } for  pid=7754 comm="dbus-daemon" capability=36
    scontext=unconfined_u:unconfined_r:unconfined_t
    tcontext=unconfined_u:unconfined_r:unconfined_t
    tclass=capability2 permissive=1

    type=SYSCALL msg=audit(1408212798.866:410): arch=c000003e syscall=233
    success=yes exit=0 a0=3 a1=2 a2=9 a3=7fffd4d66ec0 items=0 ppid=1

    fsgid=0 tty=(none) ses=3 comm="dbus-daemon"
    exe="/usr/bin/dbus-daemon"
    subj=unconfined_u:unconfined_r:unconfined_t key=(null)

("arch=c000003e syscall=233 a1=2" means "epoll_ctl(op=EPOLL_CTL_DEL)")

Remove use of epds in epoll_ctl when op == EPOLL_CTL_DEL.

Patrick Palka 000a7d66ec kernel/printk/printk.c: fix faulty logic in the case of recursive printk
We shouldn't set text_len in the code path that detects printk recursion
because text_len corresponds to the length of the string inside textbuf.
A few lines down from the line

    text_len = strlen(recursion_msg);

is the line

    text_len += vscnprintf(text + text_len, ...);

So if printk detects recursion, it sets text_len to 29 (the length of
recursion_msg) and logs an error.  Then the message supplied by the
caller of printk is stored inside textbuf but offset by 29 bytes.  This
means that the output of the recursive call to printk will contain 29
bytes of garbage in front of it.

This defect is caused by commit 458df9fd48 ("printk: remove separate
printk_sched buffers and use printk buf instead") which turned the line

    text_len = vscnprintf(text, ...);

into

    text_len += vscnprintf(text + text_len, ...);

To fix this, this patch avoids setting text_len when logging the printk
recursion error.  This patch also marks unlikely() the branch leading up
to this code.

Fixes: 458df9fd48 ("printk: remove separate printk_sched buffers and use printk buf instead")

Let memblock skip the hotpluggable memory regions in __next_mem_range(),
it is used to to prevent memblock from allocating hotpluggable memory
for the kernel at early time. The code is the same as __next_mem_range_rev().

Clear hotpluggable flag before releasing free pages to the buddy
allocator.  If we don't clear hotpluggable flag in
free_low_memory_core_early(), the memory which marked hotpluggable flag
will not free to buddy allocator.  Because __next_mem_range() will skip
them.

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of
physical buttons, instead they generate primary button click when user
presses somewhat hard on the surface of the touchpad. Unfortunately they
also report primary button click whenever there are 2 or more contacts
on the pad, messing up all multi-finger gestures (2-finger scrolling,
multi-finger tapping, etc). To cope with this behavior we introduce a
delay (currently 50 msecs) in reporting primary press in case more
contacts appear.

Chen Gang de295cf0db arch/microblaze/include/asm/uaccess.h: Use pr_devel() instead of pr_debug()
When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
also depends on the modules number in Makefile. The related information
in "scripts/Makefile.lib" line 94:

  # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
  # end up in (or would, if it gets compiled in)
  # Note: Files that end up in two or more modules are compiled without the
  #       KBUILD_MODNAME definition. The reason is that any made-up name would
  #       differ in different configs.

For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
one line, so cause compiling issue. And 'uaccess.h' is a common shared
header (not specially for drivers), so use pr_devel() instead of is OK.

It is useful for userspace to know that there not dealing with a regular
mouse but rather with a pointing stick (e.g. a trackpoint) so that
userspace can e.g. automatically enable middle button scrollwheel
emulation.

It is impossible to tell the difference from the evdev info without
resorting to putting a list of device / driver names in userspace, this is
undesirable.

Add a property which allows userspace to see if a device is a pointing
stick, and set it on all the pointing stick drivers.

====================
pull request: wireless 2014-09-05

Please pull this batch of fixes intended for the 3.17 stream...

For the mac80211 bits, Johannes says:

"Here are a few fixes for mac80211. One has been discussed for a while
and adds a terminating NUL-byte to the alpha2 sent to userspace, which
shouldn't be necessary but since many places treat it as a string we
couldn't move to just sending two bytes.

In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
fix for the recently introduced RX aggregation offload, a revert for
a broken patch (that luckily didn't really cause any harm) and a small
fix for alignment in debugfs."

For the iwlwifi bits, Emmanuel says:

"I revert a patch that disabled CTS to self in dvm because users
reported issues. The revert is CCed to stable since the offending
patch was sent to stable too. I also bump the firmware API versions
since a new firmware is coming up. On top of that, Marcel fixes a
bug I introduced while fixing a bug in our Kconfig file."

Please let me know if there are problems!

WANG Cong de185ab46c ipv6: restore the behavior of ipv6_sock_ac_drop()
It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.

What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.

  (intel_pstate and generic PM domains).

  Specifics:

   - Fix for recently broken test_suspend= command line argument (Rafael
     Wysocki).

   - Fixes for regressions related to the ACPI video driver caused by
     switching the default to native backlight handling in 3.16 from
     Hans de Goede.

   - Fix for a sysfs attribute of ACPI device objects that returns stale
     values sometimes due to the fact that they are cached instead of
     executing the appropriate method (_SUN) every time (broken in
     3.14).  From Yasuaki Ishimatsu.

   - Fix for a deadlock between cpuidle_lock and cpu_hotplug.lock in the
     ACPI processor driver from Jiri Kosina.

   - Runtime output validation for the ACPI _DSD device configuration
     object missing from the support for it that has been introduced
     recently.  From Mika Westerberg.

   - Fix for an unuseful and misleading RAPL (Running Average Power
     Limit) domain detection message in the RAPL driver from Jacob Pan.

   - New Intel Haswell CPU ID for the RAPL driver from Jason Baron.

   - New Clevo W350etq blacklist entry for the ACPI EC driver from Lan
     Tianyu.

   - Cleanup for the intel_pstate driver and the core generic PM domains
     code from Gabriele Mazzotta and Geert Uytterhoeven"

Pull filesystem fixes from Al Viro:
 "Several bugfixes (all of them -stable fodder).

  Alexey's one deals with double mutex_lock() in UFS (apparently, nobody
  has tried to test "ufs: sb mutex merge + mutex_destroy" on something
  like file creation/removal on ufs).  Mine deal with two kinds of
  umount bugs, in umount propagation and in handling of automounted
  submounts, both resulting in bogus transient EBUSY from umount"
