usbnet: do not pretend to support SG/TSO
[ Upstream commit 20f0170377264e8449b6987041f0bcc4d746d3ed ]
usbnet doesn't support yet SG, so drivers should not advertise SG or TSO
capabilities, as they allow TCP stack to build large TSO packets that
need to be linearized and might use order-5 pages.
This adds an extra copy overhead and possible allocation failures.
Current code ignore skb_linearize() return code so crashes are even
possible.
Best is to not pretend SG/TSO is supported, and add this again when/if
usbnet really supports SG for devices who could get a performance gain.

sctp: fully initialize sctp_outq in sctp_outq_init
[ Upstream commit c5c7774d7eb4397891edca9ebdf750ba90977a69 ]
In commit 2f94aabd9f6c925d77aecb3ff020f1cc12ed8f86
(refactor sctp_outq_teardown to insure proper re-initalization)
we modified sctp_outq_teardown to use sctp_outq_init to fully re-initalize the
outq structure. Steve West recently asked me why I removed the q->error = 0
initalization from sctp_outq_teardown. I did so because I was operating under
the impression that sctp_outq_init would properly initalize that value for us,
but it doesn't. sctp_outq_init operates under the assumption that the outq
struct is all 0's (as it is when called from sctp_association_init), but using
it in __sctp_outq_teardown violates that assumption. We should do a memset in
sctp_outq_init to ensure that the entire structure is in a known state there
instead.

perf: Use css_tryget() to avoid propping up css refcount
commit 9c5da09d266ca9b32eb16cf940f8161d949c2fe5 upstream.
An rmdir pushes css's ref count to zero. However, if the associated
directory is open at the time, the dentry ref count is non-zero. If
the fd for this directory is then passed into perf_event_open, it
does a css_get(). This bounces the ref count back up from zero. This
is a problem by itself. But what makes it turn into a crash is the
fact that we end up doing an extra dput, since we perform a dput
when css_put sees the ref count go down to zero.
css_tryget() does not fall into that trap. So, we use that instead.
Reproduction test-case for the bug:
#include <unistd.h>
#include <sys/types.h>

x86, fpu: correct the asm constraints for fxsave, unbreak mxcsr.daz

GCC will optimize mxcsr_feature_mask_init in arch/x86/kernel/i387.c:
memset(&fx_scratch, 0, sizeof(struct i387_fxsave_struct));
asm volatile("fxsave %0" : : "m" (fx_scratch));
mask = fx_scratch.mxcsr_mask;
if (mask == 0)
mask = 0x0000ffbf;
to
memset(&fx_scratch, 0, sizeof(struct i387_fxsave_struct));
asm volatile("fxsave %0" : : "m" (fx_scratch));
mask = 0x0000ffbf;
since asm statement doesn’t say it will update fx_scratch. As the
result, the DAZ bit will be cleared. This patch fixes it. This bug
dates back to at least kernel 2.6.12.

perf: Fix event group context move
commit 0231bb5336758426b44ccd798ccd3c5419c95d58 upstream.
When we have group with mixed events (hw/sw) we want to end up
with group leader being in hw context. So if group leader is
initialy sw event, we move all the events under hw context.
The move is done for each event by removing it from its context
and adding it back into proper one. As a part of the removal the
event is automatically disabled, which is not what we want at
this stage of creating groups.
The fix is to initialize event state after removal from sw
context.
This fix resulted from the following discussion:

sched: Fix the broken sched_rr_get_interval()
commit a59f4e079d19464eebb9b06513a1d4f55fdae5ba upstream.
The caller of sched_sliced() should pass se.cfs_rq and se as the
arguments, however in sched_rr_get_interval() we gave it
rq.cfs_rq and se, which made the following computation obviously
wrong.
The change was introduced by commit:
77034937dc45 sched: fix crash in sys_sched_rr_get_interval()
... 5 years ago, while it had been the correct 'cfs_rq_of' before
the commit. The change seems to be irrelevant to the commit
msg, which was to return a 0 timeslice for tasks that are on an
idle runqueue. So I believe that was just a plain typo.

ACPI / battery: Fix parsing _BIX return value
commit 016d5baad04269e8559332df05f89bd95b52d6ad upstream.
The _BIX method returns extended battery info as a package.
According the ACPI spec (ACPI 5, Section 10.2.2.2), the first member
of that package should be "Revision". However, the current ACPI
battery driver treats the first member as "Power Unit" which should
be the second member. This causes the result of _BIX return data
parsing to be incorrect.
Fix this by adding a new member called 'revision' to struct
acpi_battery and adding the offsetof() information on it to
extended_info_offsets[] as the first row.

rt2x00: fix stop queue
commit e2288b66fe7ff0288382b2af671b4da558b44472 upstream.
Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following
call to rt2x00queue_pause_queue() reduce to noop, i.e we do not
stop queue in mac80211.
To fix that introduce rt2x00queue_pause_queue_nocheck() function,
which will stop queue in mac80211 directly.
Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit.
Note also that reordering operations i.e. first call to
rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race
with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue()
directly is the only available solution to fix the problem without
major rework.

mac80211: fix duplicate retransmission detection
commit 6b0f32745dcfba01d7be33acd1b40306c7a914c6 upstream.
The duplicate retransmission detection code in mac80211
erroneously attempts to do the check for every frame,
even frames that don't have a sequence control field or
that don't use it (QoS-Null frames.)
This is problematic because it causes the code to access
data beyond the end of the SKB and depending on the data
there will drop packets erroneously.
Correct the code to not do duplicate detection for such
frames.
I found this error while testing AP powersave, it lead
to retransmitted PS-Poll frames being dropped entirely
as the data beyond the end of the SKB was always zero.

nl80211: fix mgmt tx status and testmode reporting for netns
commit a0ec570f4f69c4cb700d743a915096c2c8f56a99 upstream.
These two events were sent to the default network
namespace.
This caused AP mode in a non-default netns to not
work correctly. Mgmt tx status was multicasted to
a different (default) netns instead of the one the
AP was in.

ath9k_htc: do some initial hardware configuration
commit dc2a87f519a4d8cb376ab54f22b6b98a943b51ce upstream.
Currently we configure harwdare and clock, only after
interface start. In this case, if we reload module or
reboot PC without configuring adapter, firmware will freeze.
There is no software way to reset adpter.
This patch add initial configuration and set it in
disabled state, to avoid this freeze. Behaviour of this patch
should be similar to: ifconfig wlan0 up; ifconfig wlan0 down.

serial/mxs-auart: increase time to wait for transmitter to become idle
commit 079a036f4283e2b0e5c26080b8c5112bc0cc1831 upstream.
Without this patch the driver waits ~1 ms for the UART to become idle. At
115200n8 this time is (theoretically) enough to transfer 11.5 characters
(= 115200 bits/s / (10 Bits/char) * 1ms). As the mxs-auart has a fifo size
of 16 characters the clock is gated too early. The problem is worse for
lower baud rates.
This only happens to really shut down the transmitter in the middle of a
transfer if /dev/ttyAPPx isn't opened in userspace (e.g. by a getty) but
was at least once (because the bootloader doesn't disable the transmitter).
So increase the timeout to 20 ms which should be enough for 9600n8, too.
Moreover skip gating the clock if the timeout is elapsed.

serial/mxs-auart: fix race condition in interrupt handler
commit d970d7fe65adff5efe75b4a73c4ffc9be57089f7 upstream.
The handler needs to ack the pending events before actually handling them.
Otherwise a new event might come in after it it considered non-pending or
handled and is acked then without being handled. So this event is only
noticed when the next interrupt happens.
Without this patch an i.MX28 based machine running an rt-patched kernel
regularly hangs during boot.
