From: Stefan Bader <stefan.bader@canonical.com>
commit 8d16ce540c94c9d366eb36fc91b7154d92d6397b upstream.
Added a safeguard in the shutdown case. At least while not being
attached it is also possible to trigger a kernel bug by writing into
writeback_running. This change adds the same check before trying to
wake up the thread for that case.

3.16.7-ckt24 -stable review patch. If anyone has any objections, please let me know.

From: Richard Cochran <richardcochran@gmail.com>
commit 1b9f23727abb92c5e58f139e7d180befcaa06fe0 upstream.
The posix_clock_poll function is supposed to return a bit mask of
POLLxxx values. However, in case the hardware has disappeared (due to
hot plugging for example) this code returns -ENODEV in a futile
attempt to throw an error at the file descriptor level. The kernel's
file_operations interface does not accept such error codes from the
poll method. Instead, this function aught to return POLLERR.
The value -ENODEV does, in fact, contain the POLLERR bit (and almost
all the other POLLxxx bits as well), but only by chance. This patch
fixes code to return a proper bit mask.
Credit goes to Markus Elfring for pointing out the suspicious
signed/unsigned mismatch.

From: Adrian Hunter <adrian.hunter@intel.com>
commit d9bfbb95ed598a09cf336adb0f190ee0ff802f0d upstream.
The 'ocr' parameter passed to mmc_set_signal_voltage()
defines the power-on voltage used when power cycling
after a failure to set the voltage. However, in the
case of mmc_sdio_init_card(), the value passed has the
R4_18V_PRESENT flag set which is not valid for power-on
and results in an invalid vdd. Fix by passing the card's
ocr value which does not have the flag.

From: Trond Myklebust <trond.myklebust@primarydata.com>
commit ade14a7df796d4e86bd9d181193c883a57b13db0 upstream.
If a NFSv4 client uses the cache_consistency_bitmask in order to
request only information about the change attribute, timestamps and
size, then it has not revalidated all attributes, and hence the
attribute timeout timestamp should not be updated.

commit 361cad3c89070aeb37560860ea8bfc092d545adc upstream.
We've seen this in a packet capture - I've intermixed what I
think was going on. The fix here is to grab the so_lock sooner.

1964393 -> #2 open (for read) reply seqid=2

nfs4_state_set_mode_locked(), changes state->state = [R]
state->flags is [RW]
state->state is [R], state->n_wronly == 0, state->n_rdonly == 1
1964398 -> #3 open (for write) call -> because close is already running
1964399 -> downgrade (to read) call seqid=2 (close of #1)
1964402 -> #3 open (for write) reply seqid=3
__update_open_stateid()
nfs_set_open_stateid_locked(), changes state->flags
state->flags is [RW]
state->state is [R], state->n_wronly == 0, state->n_rdonly == 1
new sequence number is exposed now via nfs4_stateid_copy()
next step would be update_open_stateflags(), pending so_lock
1964403 -> downgrade reply seqid=2, fails with OLD_STATEID (close of #1)
nfs4_close_prepare() gets so_lock and recalcs flags -> send close
1964405 -> downgrade (to read) call seqid=3 (close of #1 retry)
__update_open_stateid() gets so_lock
* update_open_stateflags() updates state->n_wronly.
nfs4_state_set_mode_locked() updates state->state
state->flags is [RW]
state->state is [RW], state->n_wronly == 1, state->n_rdonly == 1
* should have suppressed the preceding nfs4_close_prepare() from
sending open_downgrade
1964406 -> write call
1964408 -> downgrade (to read) reply seqid=4 (close of #1 retry)
nfs_clear_open_stateid_locked()
state->flags is [R]
state->state is [RW], state->n_wronly == 1, state->n_rdonly == 1
1964409 -> write reply (fails, openmode)

commit 32a844056fd43dda647e1c3c6b9983bdfa04d17d upstream.
Originally that parameter was always reset to num_online_cpus during
module initialisation, which renders it useless.
The fix is to only set max_queues to num_online_cpus when user has not
provided a value.

From: lucien <lucien.xin@gmail.com>
commit 8a0d19c5ed417c78d03f4e0fa7215e58c40896d8 upstream.
when A sends a data to B, then A close() and enter into SHUTDOWN_PENDING
state, if B neither claim his rwnd is 0 nor send SACK for this data, A
will keep retransmitting this data until t5 timeout, Max.Retrans times
can't work anymore, which is bad.
if B's rwnd is not 0, it should send abort after Max.Retrans times, only
when B's rwnd == 0 and A's retransmitting beyonds Max.Retrans times, A
will start t5 timer, which is also commit f8d960524328 ("sctp: Enforce
retransmission limit during shutdown") means, but it lacks the condition
peer rwnd == 0.
so fix it by adding a bit (zero_window_announced) in peer to record if
the last rwnd is 0. If it was, zero_window_announced will be set. and use
this bit to decide if start t5 timer when local.state is SHUTDOWN_PENDING.

From: Steven Rostedt <rostedt@goodmis.org>
commit 32abc2ede536aae52978d6c0a8944eb1df14f460 upstream.
When a long value is read on 32 bit machines for 64 bit output, the
parsing needs to change "%lu" into "%llu", as the value is read
natively.
Unfortunately, if "%llu" is already there, the code will add another "l"
to it and fail to parse it properly.

From: Wei Liu <wei.liu2@citrix.com>
commit 4c82ac3c37363e8c4ded6a5fe1ec5fa756b34df3 upstream.
Originally that parameter was always reset to num_online_cpus during
module initialisation, which renders it useless.
The fix is to only set max_queues to num_online_cpus when user has not
provided a value.

From: Uri Mashiach <uri.mashiach@compulab.co.il>
commit 9b2761cb72dc41e1948c8a5512b4efd384eda130 upstream.
The maximum chunks used by the function is
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE + 1).
The original commands array had space for
(SPI_AGGR_BUFFER_SIZE / WSPI_MAX_CHUNK_SIZE) commands.
When the last chunk is used (len > 4 * WSPI_MAX_CHUNK_SIZE), the last
command is stored outside the bounds of the commands array.
Oops 5 (page fault) is generated during current wl1271 firmware load

From: Boqun Feng <boqun.feng@gmail.com>
commit 81d7a3294de7e9828310bbf986a67246b13fa01e upstream.
According to memory-barriers.txt, xchg*, cmpxchg* and their atomic_
versions all need to be fully ordered, however they are now just
RELEASE+ACQUIRE, which are not fully ordered.
So also replace PPC_RELEASE_BARRIER and PPC_ACQUIRE_BARRIER with
PPC_ATOMIC_ENTRY_BARRIER and PPC_ATOMIC_EXIT_BARRIER in
__{cmp,}xchg_{u32,u64} respectively to guarantee fully ordered semantics
of atomic{,64}_{cmp,}xchg() and {cmp,}xchg(), as a complement of commit
b97021f85517 ("powerpc: Fix atomic_xxx_return barrier semantics")
This patch depends on patch "powerpc: Make value-returning atomics fully
ordered" for PPC_ATOMIC_ENTRY_BARRIER definition.

commit 5db4fd8c52810bd9740c1240ebf89223b171aa70 upstream.
Make sure to clear out any ptrace singlestep state when a ptrace(2)
PTRACE_DETACH call is made on arm64 systems.
Otherwise, the previously ptraced task will die off with a SIGTRAP
signal if the debugger just previously singlestepped the ptraced task.

commit dcc7fdbec53a960588f2c40232db2c6466c09917 upstream.
v4l2-compliance sends a zeroed struct v4l2_streamparm in
v4l2-test-formats.cpp::testParmType(), and this results in a division by
0 in some gspca subdrivers:

Following what the doc says about a zeroed timeperframe (see
http://www.linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-parm.html):
...
To reset manually applications can just set this field to zero.
fix the issue by resetting the frame rate to a default value in case of
an unusable timeperframe.
The fix is done in the subdrivers instead of gspca.c because only the
subdrivers have notion of a default frame rate to reset the camera to.
