[PATCH 4.9 001/222] ax88172a: fix information leak on short answers

[Greg Kroah-Hartman]

From: Oliver Neukum <oneukum@suse.com>

[ Upstream commit a9a51bd727d141a67b589f375fe69d0e54c4fe22 ]

If a malicious device gives a short MAC it can elicit up to
5 bytes of leaked memory out of the driver. We need to check for
ETH_ALEN instead.

[PATCH 4.9 002/222] slip: Fix memory leak in slip_open error path

[Greg Kroah-Hartman]

From: Jouni Hogander <jouni.hogander@unikie.com>

by Syzkaller in slcan. Same issue exists in slip.c and this patch is
addressing the leak in slip.c.

[PATCH 4.9 003/222] ALSA: usb-audio: Fix missing error check at mixer resolution test

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 167beb1756791e0806365a3f86a0da10d7a327ee upstream.

A check of the return value from get_cur_mix_raw() is missing at the
resolution test code in get_min_max_with_quirks(), which may leave the
variable untouched, leading to a random uninitialized value, as
detected by syzkaller fuzzer.

Add the missing return error check for fixing that.

[PATCH 4.9 004/222] ALSA: usb-audio: not submit urb for stopped endpoint

[Greg Kroah-Hartman]

From: Henry Lin <henryl@nvidia.com>

commit 528699317dd6dc722dccc11b68800cf945109390 upstream.

While output urb's snd_complete_urb() is executing, calling
prepare_outbound_urb() may cause endpoint stopped before
prepare_outbound_urb() returns and result in next urb submitted
to stopped endpoint. usb-audio driver cannot re-use it afterwards as
the urb is still hold by usb stack.

This change checks EP_FLAG_RUNNING flag after prepare_outbound_urb() again
to let snd_complete_urb() know the endpoint already stopped and does not
submit next urb. Below kind of error will be fixed:

[  213.153103] usb 1-2: timeout: still 1 active urbs on EP #1
[  213.164121] usb 1-2: cannot submit urb 0, error -16: unknown error

[PATCH 4.9 006/222] Input: synaptics-rmi4 - fix video buffer size

[Greg Kroah-Hartman]

From: Lucas Stach <l.stach@pengutronix.de>

commit 003f01c780020daa9a06dea1db495b553a868c29 upstream.

The video buffer used by the queue is a vb2_v4l2_buffer, not a plain
vb2_buffer. Using the wrong type causes the allocation of the buffer
storage to be too small, causing a out of bounds write when
__init_vb2_v4l2_buffer initializes the buffer.

[PATCH 4.9 007/222] Input: synaptics-rmi4 - clear IRQ enables for F54

[Greg Kroah-Hartman]

From: Lucas Stach <l.stach@pengutronix.de>

commit 549766ac2ac1f6c8bb85906bbcea759541bb19a2 upstream.

The driver for F54 just polls the status and doesn't even have a IRQ
handler registered. Make sure to disable all F54 IRQs, so we don't crash
the kernel on a nonexistent handler.

[PATCH 4.9 008/222] Input: synaptics-rmi4 - destroy F54 poller workqueue when removing

[Greg Kroah-Hartman]

From: Chuhong Yuan <hslester96@gmail.com>

commit ba60cf9f78f0d7c8e73c7390608f7f818ee68aa0 upstream.

The driver forgets to destroy workqueue in remove() similarly to what is
done when probe() fails. Add a call to destroy_workqueue() to fix it.

Since unregistration will wait for the work to finish, we do not need to
cancel/flush the work instance in remove().

[PATCH 4.9 009/222] IB/hfi1: Ensure full Gen3 speed in a Gen4 system

[Greg Kroah-Hartman]

From: James Erwin <james.erwin@intel.com>

commit a9c3c4c597704b3a1a2b9bef990e7d8a881f6533 upstream.

If an hfi1 card is inserted in a Gen4 systems, the driver will avoid the
gen3 speed bump and the card will operate at half speed.

This is because the driver avoids the gen3 speed bump when the parent bus
speed isn't identical to gen3, 8.0GT/s.  This is not compatible with gen4
and newer speeds.

Fix by relaxing the test to explicitly look for the lower capability
speeds which inherently allows for gen4 and all future speeds.

[PATCH 4.9 010/222] ecryptfs_lookup_interpose(): lower_dentry->d_inode is not stable

[Greg Kroah-Hartman]

From: Al Viro <viro@zeniv.linux.org.uk>

commit e72b9dd6a5f17d0fb51f16f8685f3004361e83d0 upstream.

lower_dentry can't go from positive to negative (we have it pinned),
but it *can* go from negative to positive.  So fetching ->d_inode
into a local variable, doing a blocking allocation, checking that
now ->d_inode is non-NULL and feeding the value we'd fetched
earlier to a function that won't accept NULL is not a good idea.

[PATCH 4.9 011/222] ecryptfs_lookup_interpose(): lower_dentry->d_parent is not stable either

[Greg Kroah-Hartman]

From: Al Viro <viro@zeniv.linux.org.uk>

commit 762c69685ff7ad5ad7fee0656671e20a0c9c864d upstream.

We need to get the underlying dentry of parent; sure, absent the races
it is the parent of underlying dentry, but there's nothing to prevent
losing a timeslice to preemtion in the middle of evaluation of
lower_dentry->d_parent->d_inode, having another process move lower_dentry
around and have its (ex)parent not pinned anymore and freed on memory
pressure.  Then we regain CPU and try to fetch ->d_inode from memory
that is freed by that point.

dentry->d_parent *is* stable here - it's an argument of ->lookup() and
we are guaranteed that it won't be moved anywhere until we feed it
to d_add/d_splice_alias.  So we safely go that way to get to its
underlying dentry.

[PATCH 4.9 013/222] mm: memcg: switch to css_tryget() in get_mem_cgroup_from_mm()

[Greg Kroah-Hartman]

From: Roman Gushchin <guro@fb.com>

commit 00d484f354d85845991b40141d40ba9e5eb60faf upstream.

We've encountered a rcu stall in get_mem_cgroup_from_mm():

   entry_SYSCALL_64_after_hwframe+0x44/0xa9

The problem is caused by an exiting task which is associated with an
offline memcg.  We're iterating over and over in the do {} while
(!css_tryget_online()) loop, but obviously the memcg won't become online
and the exiting task won't be migrated to a live memcg.

Let's fix it by switching from css_tryget_online() to css_tryget().

As css_tryget_online() cannot guarantee that the memcg won't go offline,
the check is usually useless, except some rare cases when for example it
determines if something should be presented to a user.

A similar problem is described by commit 18fa84a2db0e ("cgroup: Use
css_tryget() instead of css_tryget_online() in task_get_css()").

Johannes:

: The bug aside, it doesn't matter whether the cgroup is online for the
: callers.  It used to matter when offlining needed to evacuate all charges
: from the memcg, and so needed to prevent new ones from showing up, but we
: don't care now.

[PATCH 4.9 014/222] mm: hugetlb: switch to css_tryget() in hugetlb_cgroup_charge_cgroup()

[Greg Kroah-Hartman]

From: Roman Gushchin <guro@fb.com>

commit 0362f326d86c645b5e96b7dbc3ee515986ed019d upstream.

An exiting task might belong to an offline cgroup.  In this case an
attempt to grab a cgroup reference from the task can end up with an
infinite loop in hugetlb_cgroup_charge_cgroup(), because neither the
cgroup will become online, neither the task will be migrated to a live
cgroup.

Fix this by switching over to css_tryget().  As css_tryget_online()
can't guarantee that the cgroup won't go offline, in most cases the
check doesn't make sense.  In this particular case users of
hugetlb_cgroup_charge_cgroup() are not affected by this change.

A similar problem is described by commit 18fa84a2db0e ("cgroup: Use
css_tryget() instead of css_tryget_online() in task_get_css()").

[PATCH 4.9 016/222] ath10k: fix kernel panic by moving pci flush after napi_disable

[Greg Kroah-Hartman]

From: Tamizh chelvam <tamizhr@codeaurora.org>

[ Upstream commit bd1d395070cca4f42a93e520b0597274789274a4 ]

When continuously running wifi up/down sequence, the napi poll
can be scheduled after the CE buffers being freed by ath10k_pci_flush

Steps:
  In a certain condition, during wifi down below scenario might occur.

ath10k_stop->ath10k_hif_stop->napi_schedule->ath10k_pci_flush->napi_poll(napi_synchronize).

In the above scenario, CE buffer entries will be freed up and become NULL in
ath10k_pci_flush. And the napi_poll has been invoked after the flush process
and it will try to get the skb from the CE buffer entry and perform some action on that.
Since the CE buffer already cleaned by pci flush this action will create NULL
pointer dereference and trigger below kernel panic.

[PATCH 4.9 021/222] cfg80211: Avoid regulatory restore when COUNTRY_IE_IGNORE is set

[Greg Kroah-Hartman]

From: Rajeev Kumar Sirasanagandla <rsirasan@codeaurora.org>

[ Upstream commit 7417844b63d4b0dc8ab23f88259bf95de7d09b57 ]

When REGULATORY_COUNTRY_IE_IGNORE is set,  __reg_process_hint_country_ie()
ignores the country code change request from __cfg80211_connect_result()
via regulatory_hint_country_ie().

After Disconnect, similar to above, country code should not be reset to
world when country IE ignore is set. But this is violated and restore of
regulatory settings is invoked by cfg80211_disconnect_work via
regulatory_hint_disconnect().

To address this, avoid regulatory restore from regulatory_hint_disconnect()
when COUNTRY_IE_IGNORE is set.

Note: Currently, restore_regulatory_settings() takes care of clearing
beacon hints. But in the proposed change, regulatory restore is avoided.
Therefore, explicitly clear beacon hints when DISABLE_BEACON_HINTS
is not set.

From: Felix Fietkau <nbd@nbd.name>

[ Upstream commit d9c52fd17cb483bd8a470398afcb79f86c1b77c8 ]

Tx99 is typically configured via a monitor mode interface, which does
not get added to the driver as a vif. Since the code currently expects
a configured virtual interface for tx99, enabling tx99 via debugfs fails.
Since the vif is not needed anyway, remove all checks for it.

[PATCH 4.9 024/222] gfs2: Dont set GFS2_RDF_UPTODATE when the lvb is updated

[Greg Kroah-Hartman]

From: Bob Peterson <rpeterso@redhat.com>

[ Upstream commit 4f36cb36c9d14340bb200d2ad9117b03ce992cfe ]

The GFS2_RDF_UPTODATE flag in the rgrp is used to determine when
a rgrp buffer is valid. It's cleared when the glock is invalidated,
signifying that the buffer data is now invalid. But before this
patch, function update_rgrp_lvb was setting the flag when it
determined it had a valid lvb. But that's an invalid assumption:
just because you have a valid lvb doesn't mean you have valid
buffers. After all, another node may have made the lvb valid,
and this node just fetched it from the glock via dlm.

Consider this scenario:
1. The file system is mounted with RGRPLVB option.
2. In gfs2_inplace_reserve it locks the rgrp glock EX, but thanks
   to GL_SKIP, it skips the gfs2_rgrp_bh_get.
3. Since loops == 0 and the allocation target (ap->target) is
   bigger than the largest known chunk of blocks in the rgrp
   (rs->rs_rbm.rgd->rd_extfail_pt) it skips that rgrp and bypasses
   the call to gfs2_rgrp_bh_get there as well.
4. update_rgrp_lvb sees the lvb MAGIC number is valid, so bypasses
   gfs2_rgrp_bh_get, but it still sets sets GFS2_RDF_UPTODATE due
   to this invalid assumption.
5. The next time update_rgrp_lvb is called, it sees the bit is set
   and just returns 0, assuming both the lvb and rgrp are both
   uptodate. But since this is a smaller allocation, or space has
   been freed by another node, thus adjusting the lvb values,
   it decides to use the rgrp for allocations, with invalid rd_free
   due to the fact it was never updated.

This patch changes update_rgrp_lvb so it doesn't set the UPTODATE
flag anymore. That way, it has no choice but to fetch the latest
values.

[PATCH 4.9 025/222] ASoC: dpcm: Properly initialise hw->rate_max

[Greg Kroah-Hartman]

From: Charles Keepax <ckeepax@opensource.cirrus.com>

[ Upstream commit e33ffbd9cd39da09831ce62c11025d830bf78d9e ]

If the CPU DAI does not initialise rate_max, say if using
using KNOT or CONTINUOUS, then the rate_max field will be
initialised to 0. A value of zero in the rate_max field of
the hardware runtime will cause the sound card to support no
sample rates at all. Obviously this is not desired, just a
different mechanism is being used to apply the constraints. As
such update the setting of rate_max in dpcm_init_runtime_hw
to be consistent with the non-DPCM cases and set rate_max to
UINT_MAX if nothing is defined on the CPU DAI.

[PATCH 4.9 028/222] ARM: dts: exynos: Fix regulators configuration on Peach Pi/Pit Chromebooks

[Greg Kroah-Hartman]

From: Marek Szyprowski <m.szyprowski@samsung.com>

[ Upstream commit f8f3b7fc21b1cb59385b780acd9b9a26d04cb7b2 ]

Regulators, which are marked as 'on-in-suspend' seems to be critical for
board operation, thus they must not be disabled anytime. This can be
only assured by marking them as 'always-on', because otherwise some
actions of their clients might result in turning them off. This patch
restores suspend/resume operation on Peach-Pit Chromebook board. It
partially reverts 'always-on' property removal done by the commit
mentioned in the Fixes tag.

[PATCH 4.9 032/222] IB/rxe: fixes for rdma read retry

[Greg Kroah-Hartman]

From: Vijay Immanuel <vijayi@attalasystems.com>

[ Upstream commit 030e46e495af855a13964a0aab9753ea82a96edc ]

When a read request is retried for the remaining partial
data, the response may restart from read response first
or read response only. So support those cases.

Do not advance the comp psn beyond the current wqe's last_psn
as that could skip over an entire read wqe and will cause the
req_retry() logic to set an incorrect req psn.
An example sequence is as follows:
Write        PSN 40 -- this is the current WQE.
Read request PSN 41
Write        PSN 42
Receive ACK  PSN 42 -- this will complete the current WQE
for PSN 40, and set the comp psn to 42 which is a problem
because the read request at PSN 41 has been skipped over.
So when req_retry() tries to retransmit the read request,
it sets the req psn to 42 which is incorrect.

When retrying a read request, calculate the number of psns
completed based on the dma resid instead of the wqe first_psn.
The wqe first_psn could have moved if the read request was
retried multiple times.

Set the reth length to the dma resid to handle read retries for
the remaining partial data.

[ Upstream commit 1a19c139be18ed4d6d681049cc48586fae070120 ]

When we receive TX response, we may release a few packets
due to a hole that was closed in the transmission window.

However, if that frame failed, we will mark all the released
frames as failed and will send multiple BARs.

This affects statistics badly, and cause unnecessary frames
transmission.

Instead, mark all the following packets as success, with the
desired result of sending a bar for the failed frame only.

[PATCH 4.9 037/222] ASoC: sgtl5000: avoid division by zero if lo_vag is zero

[Greg Kroah-Hartman]

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 9ab708aef61f5620113269a9d1bdb1543d1207d0 ]

In the case where lo_vag <= SGTL5000_LINE_OUT_GND_BASE, lo_vag
is set to zero and later vol_quot is computed by dividing by
lo_vag causing a division by zero error.  Fix this by avoiding
a zero division and set vol_quot to zero in this specific case
so that the lowest setting for i is correctly set.

[PATCH 4.9 039/222] ath10k: wmi: disable softirqs while calling ieee80211_rx

[Greg Kroah-Hartman]

From: Erik Stromdahl <erik.stromdahl@gmail.com>

[ Upstream commit 37f62c0d5822f631b786b29a1b1069ab714d1a28 ]

This is done in order not to trig the below warning in
ieee80211_rx_napi:

WARN_ON_ONCE(softirq_count() == 0);

ieee80211_rx_napi requires that softirq's are disabled during
execution.

The High latency bus drivers (SDIO and USB) sometimes call the wmi
ep_rx_complete callback from non softirq context, resulting in a trigger
of the above warning.

Calling ieee80211_rx_ni with softirq's already disabled (e.g., from
softirq context) should be safe as the local_bh_disable and
local_bh_enable functions (called from ieee80211_rx_ni) are fully
reentrant.

[PATCH 4.9 050/222] dmaengine: dma-jz4780: Further residue status fix

[Greg Kroah-Hartman]

From: Daniel Silsby <dansilsby@gmail.com>

[ Upstream commit 83ef4fb7556b6a673f755da670cbacab7e2c7f1b ]

Func jz4780_dma_desc_residue() expects the index to the next hw
descriptor as its last parameter. Caller func jz4780_dma_tx_status(),
however, applied modulus before passing it. When the current hw
descriptor was last in the list, the index passed became zero.

The resulting excess of reported residue especially caused problems
with cyclic DMA transfer clients, i.e. ALSA AIC audio output, which
rely on this for determining current DMA location within buffer.

Combined with the recent and related residue-reporting fixes, spurious
ALSA audio underruns on jz4770 hardware are now fixed.

[PATCH 4.9 051/222] ath9k: add back support for using active monitor interfaces for tx99

[Greg Kroah-Hartman]

From: Felix Fietkau <nbd@nbd.name>

[ Upstream commit 6df0580be8bc30803c4d8b2ed9c2230a2740c795 ]

Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.

This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

[PATCH 4.9 052/222] signal: Always ignore SIGKILL and SIGSTOP sent to the global init

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

[ Upstream commit 86989c41b5ea08776c450cb759592532314a4ed6 ]

If the first process started (aka /sbin/init) receives a SIGKILL it
will panic the system if it is delivered.  Making the system unusable
and undebugable.  It isn't much better if the first process started
receives SIGSTOP.

So always ignore SIGSTOP and SIGKILL sent to init.

This is done in a separate clause in sig_task_ignored as force_sig_info
can clear SIG_UNKILLABLE and this protection should work even then.

[PATCH 4.9 053/222] signal: Properly deliver SIGILL from uprobes

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

[ Upstream commit 55a3235fc71bf34303e34a95eeee235b2d2a35dd ]

For userspace to tell the difference between a random signal and an
exception, the exception must include siginfo information.

Using SEND_SIG_FORCED for SIGILL is thus wrong, and it will result
in userspace seeing si_code == SI_USER (like a random signal) instead
of si_code == SI_KERNEL or a more specific si_code as all exceptions
deliver.

Therefore replace force_sig_info(SIGILL, SEND_SIG_FORCE, current)
with force_sig(SIG_ILL, current) which gets this right and is
shorter and easier to type.

[PATCH 4.9 060/222] kprobes: Dont call BUG_ON() if there is a kprobe in use on free list

[Greg Kroah-Hartman]

From: Masami Hiramatsu <mhiramat@kernel.org>

[ Upstream commit cbdd96f5586151e48317d90a403941ec23f12660 ]

Instead of calling BUG_ON(), if we find a kprobe in use on free kprobe
list, just remove it from the list and keep it on kprobe hash list
as same as other in-use kprobes.

nvmem_device_get() should return ERR_PTR() on error or valid pointer
on success, but one of the code path seems to return NULL, so fix it.

[PATCH 4.9 063/222] media: dvb: fix compat ioctl translation

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 1ccbeeb888ac33627d91f1ccf0b84ef3bcadef24 ]

The VIDEO_GET_EVENT and VIDEO_STILLPICTURE was added back in 2005 but
it never worked because the command number is wrong.

Using the right command number means we have a better chance of them
actually doing the right thing, though clearly nobody has ever tried
it successfully.

I noticed these while auditing the remaining users of compat_time_t
for y2038 bugs. This one is fine in that regard, it just never did
anything.

Fixes: 6e87abd0b8cb ("[DVB]: Add compat ioctl handling.")

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 7064f376d4a10686f51c879401a569bb4babf9c6 ]

The interrupt handler has to be acquired after the other resource
initialization when allocated with IRQF_SHARED.  Otherwise it's
triggered before the resource gets ready, and may lead to unpleasant
behavior.

The "has_config" variable is either uninitialized or true.  The
"num_pins" variable is unsigned and we verified that it is non-zero on
the lines before so we know "num_pines >= 1" is true.  Really, we could
just check "num_configs" directly and remove the "has_config" variable.

[PATCH 4.9 066/222] llc: avoid blocking in llc_sap_close()

[Greg Kroah-Hartman]

From: Cong Wang <xiyou.wangcong@gmail.com>

[ Upstream commit 9708d2b5b7c648e8e0a40d11e8cea12f6277f33c ]

llc_sap_close() is called by llc_sap_put() which
could be called in BH context in llc_rcv(). We can't
block in BH.

There is no reason to block it here, kfree_rcu() should
be sufficient.

[PATCH 4.9 067/222] ARM: dts: qcom: ipq4019: fix cpu0s qcom,saw2 reg value

[Greg Kroah-Hartman]

From: Christian Lamparter <chunkeey@gmail.com>

[ Upstream commit bd73a3dd257fb838bd456a18eeee0ef0224b7a40 ]

while compiling an ipq4019 target, dtc will complain:
regulator@b089000 unit address format error, expected "2089000"

The saw0 regulator reg value seems to be
copied and pasted from qcom-ipq8064.dtsi.

This patch fixes the reg value to match that of the
unit address which in turn silences the warning.
(There is no driver for qcom,saw2 right now.
So this went unnoticed)

[PATCH 4.9 068/222] powerpc/vdso: Correct call frame information

[Greg Kroah-Hartman]

From: Alan Modra <amodra@gmail.com>

[ Upstream commit 56d20861c027498b5a1112b4f9f05b56d906fdda ]

Call Frame Information is used by gdb for back-traces and inserting
breakpoints on function return for the "finish" command.  This failed
when inside __kernel_clock_gettime.  More concerning than difficulty
debugging is that CFI is also used by stack frame unwinding code to
implement exceptions.  If you have an app that needs to handle
asynchronous exceptions for some reason, and you are unlucky enough to
get one inside the VDSO time functions, your app will crash.

What's wrong:  There is control flow in __kernel_clock_gettime that
reaches label 99 without saving lr in r12.  CFI info however is
interpreted by the unwinder without reference to control flow: It's a
simple matter of "Execute all the CFI opcodes up to the current
address".  That means the unwinder thinks r12 contains the return
address at label 99.  Disabuse it of that notion by resetting CFI for
the return address at label 99.

Note that the ".cfi_restore lr" could have gone anywhere from the
"mtlr r12" a few instructions earlier to the instruction at label 99.
I put the CFI as late as possible, because in general that's best
practice (and if possible grouped with other CFI in order to reduce
the number of CFI opcodes executed when unwinding).  Using r12 as the
return address is perfectly fine after the "mtlr r12" since r12 on
that code path still contains the return address.

__get_datapage also has a CFI error.  That function temporarily saves
lr in r0, and reflects that fact with ".cfi_register lr,r0".  A later
use of r0 means the CFI at that point isn't correct, as r0 no longer
contains the return address.  Fix that too.

gpiochip to register is then disrupted.

[PATCH 4.9 075/222] component: fix loop condition to call unbind() if bind() fails

[Greg Kroah-Hartman]

From: Banajit Goswami <bgoswami@codeaurora.org>

[ Upstream commit bdae566d5d9733b6e32b378668b84eadf28a94d4 ]

During component_bind_all(), if bind() fails for any
particular component associated with a master, unbind()
should be called for all previous components in that
master's match array, whose bind() might have completed
successfully. As per the current logic, if bind() fails
for the component at position 'n' in the master's match
array, it would start calling unbind() from component in
'n'th position itself and work backwards, and will always
skip calling unbind() for component in 0th position in the
master's match array.
Fix this by updating the loop condition, and the logic to
refer to the components in master's match array, so that
unbind() is called for all components starting from 'n-1'st
position in the array, until (and including) component in
0th position.

[PATCH 4.9 076/222] kernfs: Fix range checks in kernfs_get_target_path

From: Bernd Edlinger <bernd.edlinger@hotmail.de>

[ Upstream commit a75e78f21f9ad4b810868c89dbbabcc3931591ca ]

The terminating NUL byte is only there because the buffer is
allocated with kzalloc(PAGE_SIZE, GFP_KERNEL), but since the
range-check is off-by-one, and PAGE_SIZE==PATH_MAX, the
returned string may not be zero-terminated if it is exactly
PATH_MAX characters long.  Furthermore also the initial loop
may theoretically exceed PATH_MAX and cause a fault.

[PATCH 4.9 077/222] ip_gre: fix parsing gre header in ipgre_err

[Greg Kroah-Hartman]

From: Haishuang Yan <yanhaishuang@cmss.chinamobile.com>

[ Upstream commit b0350d51f001e6edc13ee4f253b98b50b05dd401 ]

gre_parse_header stops parsing when csum_err is encountered, which means
tpi->key is undefined and ip_tunnel_lookup will return NULL improperly.

This patch introduce a NULL pointer as csum_err parameter. Even when
csum_err is encountered, it won't return error and continue parsing gre
header as expected.

We tried to revert commit d9c52fd17cb4 ("ath9k: fix tx99 with monitor
mode interface") but accidentally missed part of the locking change.

The lock has to be held earlier so that we're holding it when we do
"sc->tx99_vif = vif;" and also there in the current code there is a
stray unlock before we have taken the lock.

[PATCH 4.9 080/222] s390/qeth: invoke softirqs after napi_schedule()

[Greg Kroah-Hartman]

From: Julian Wiedmann <jwi@linux.ibm.com>

[ Upstream commit 4d19db777a2f32c9b76f6fd517ed8960576cb43e ]

Calling napi_schedule() from process context does not ensure that the
NET_RX softirq is run in a timely fashion. So trigger it manually.

This is no big issue with current code. A call to ndo_open() is usually
followed by a ndo_set_rx_mode() call, and for qeth this contains a
spin_unlock_bh(). Except for OSN, where qeth_l2_set_rx_mode() bails out
early.
Nevertheless it's best to not depend on this behaviour, and just fix
the issue at its source like all other drivers do. For instance see
commit 83a0c6e58901 ("i40e: Invoke softirqs after napi_reschedule").

[PATCH 4.9 085/222] powerpc/pseries: Disable CPU hotplug across migrations

[Greg Kroah-Hartman]

From: Nathan Fontenot <nfont@linux.vnet.ibm.com>

[ Upstream commit 85a88cabad57d26d826dd94ea34d3a785824d802 ]

When performing partition migrations all present CPUs must be online
as all present CPUs must make the H_JOIN call as part of the migration
process. Once all present CPUs make the H_JOIN call, one CPU is returned
to make the rtas call to perform the migration to the destination system.

During testing of migration and changing the SMT state we have found
instances where CPUs are offlined, as part of the SMT state change,
before they make the H_JOIN call. This results in a hung system where
every CPU is either in H_JOIN or offline.

To prevent this this patch disables CPU hotplug during the migration
process.

[PATCH 4.9 086/222] RDMA/i40iw: Fix incorrect iterator type

[Greg Kroah-Hartman]

From: Håkon Bugge <Haakon.Bugge@oracle.com>

[ Upstream commit 802fa45cd320de319e86c93bca72abec028ba059 ]

Commit f27b4746f378 ("i40iw: add connection management code") uses an
incorrect rcu iterator, whilst holding the rtnl_lock. Since the
critical region invokes i40iw_manage_qhash(), which is a sleeping
function, the rcu locking and traversal cannot be used.

From: Andreas Kemnade <andreas@kemnade.info>

[ Upstream commit 8314c212f995bc0d06b54ad02ef0ab4089781540 ]

the charging current uses unsigned int variables, if we step back
if the current is still low, we would run into negative which
means setting the target to a huge value.
Better add checks here.

[PATCH 4.9 091/222] net: xilinx: fix return type of ndo_start_xmit function

[Greg Kroah-Hartman]

From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit 81255af8d9d5565004792c295dde49344df450ca ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

[PATCH 4.9 094/222] usb: chipidea: imx: enable OTG overcurrent in case USB subsystem is already started

[Greg Kroah-Hartman]

From: Nicolas Adell <nicolas.adell@actia.fr>

[ Upstream commit 1dedbdf2bbb1ede8d96f35f9845ecae179dc1988 ]

When initializing the USB subsystem before starting the kernel,
OTG overcurrent detection is disabled. In case the OTG polarity of
overcurrent is low active, the overcurrent detection is never enabled
again and events cannot be reported as expected. Because imx usb
overcurrent polarity is low active by default, only detection needs
to be enable in usbmisc init function.

At OTG work running time, it's possible that several events need to be
addressed (e.g. ID and VBUS events). The current implementation handles
only one event at a time which leads to ignoring the other one. Fix it.

[PATCH 4.9 096/222] mlxsw: spectrum: Init shaper for TCs 8..15

[Greg Kroah-Hartman]

From: Petr Machata <petrm@mellanox.com>

[ Upstream commit a9f36656b519a9a21309793c306941a3cd0eeb8f ]

With introduction of MC-aware mode to mlxsw, it became necessary to
configure TCs above 7 as well. There is now code in mlxsw to disable ETS
for these higher classes, but disablement of max shaper was neglected.

By default, max shaper is currently disabled to begin with, so the
problem is just cosmetic. However, for symmetry, do like we do for ETS
configuration, and call mlxsw_sp_port_ets_maxrate_set() for both TC i
and i + 8.

am335x-evm has only one CPSW external port physically wired, but DT defines
2 ext. ports. As result, PHY connection failure reported for the second
ext. port.

Update DT to reflect am335x-evm board HW configuration, and, while here,
switch to use phy-handle instead of phy_id.

[PATCH 4.9 098/222] f2fs: fix to recover inodes uid/gid during POR

[Greg Kroah-Hartman]

From: Chao Yu <yuchao0@huawei.com>

[ Upstream commit dc4cd1257c86451cec3e8e352cc376348e4f4af4 ]

Step to reproduce this bug:
1. logon as root
2. mount -t f2fs /dev/sdd /mnt;
3. touch /mnt/file;
4. chown system /mnt/file; chgrp system /mnt/file;
5. xfs_io -f /mnt/file -c "fsync";
6. godown /mnt;
7. umount /mnt;
8. mount -t f2fs /dev/sdd /mnt;

After step 8) we will expect file's uid/gid are all system, but during
recovery, these two fields were not been recovered, fix it.

[PATCH 4.9 103/222] cpufeature: avoid warning when compiling with clang

[Greg Kroah-Hartman]

From: Stefan Agner <stefan@agner.ch>

[ Upstream commit c785896b21dd8e156326ff660050b0074d3431df ]

The table id (second) argument to MODULE_DEVICE_TABLE is often
referenced otherwise. This is not the case for CPU features. This
leads to warnings when building the kernel with Clang:
  arch/arm/crypto/aes-ce-glue.c:450:1: warning: variable
    'cpu_feature_match_AES' is not needed and will not be emitted
    [-Wunneeded-internal-declaration]
  module_cpu_feature_match(AES, aes_init);
  ^

Avoid warnings by using __maybe_unused, similar to commit 1f318a8bafcf
("modules: mark __inittest/__exittest as __maybe_unused").

This is a workaround for FW bug -
MFW generates bandwidth attention in single function mode, which
is only expected to be generated in multi function mode.
This undesired attention in SF mode results in incorrect HW
configuration and resulting into Tx timeout.

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

[PATCH 4.9 107/222] x86/CPU: Use correct macros for Cyrix calls

[Greg Kroah-Hartman]

From: Matthew Whitehead <tedheadster@gmail.com>

[ Upstream commit 03b099bdcdf7125d4a63dc9ddeefdd454e05123d ]

There are comments in processor-cyrix.h advising you to _not_ make calls
using the deprecated macros in this style:

  setCx86_old(CX86_CCR4, getCx86_old(CX86_CCR4) | 0x80);

This is because it expands the macro into a non-functioning calling
sequence. The calling order must be:

  outb(CX86_CCR2, 0x22);
  inb(0x23);

>From the comments:

 * When using the old macros a line like
 *   setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
 * gets expanded to:
 *  do {
 *    outb((CX86_CCR2), 0x22);
 *    outb((({
 *        outb((CX86_CCR2), 0x22);
 *        inb(0x23);
 *    }) | 0x88), 0x23);
 *  } while (0);

The new macros fix this problem, so use them instead.

[PATCH 4.9 108/222] MIPS: kexec: Relax memory restriction

[Greg Kroah-Hartman]

From: Dengcheng Zhu <dzhu@wavecomp.com>

[ Upstream commit a6da4d6fdf8bd512c98d3ac7f1d16bc4bb282919 ]

We can rely on the system kernel and the dump capture kernel themselves in
memory usage.

Being restrictive with 512MB limit may cause kexec tool failure on some
platforms.

[PATCH 4.9 109/222] media: pci: ivtv: Fix a sleep-in-atomic-context bug in ivtv_yuv_init()

[ Upstream commit 8d11eb847de7d89c2754988c944d51a4f63e219b ]

The driver may sleep in a interrupt handler.

The function call paths (from bottom to top) in Linux-4.16 are:

[FUNC] kzalloc(GFP_KERNEL)
drivers/media/pci/ivtv/ivtv-yuv.c, 938:
	kzalloc in ivtv_yuv_init
drivers/media/pci/ivtv/ivtv-yuv.c, 960:
	ivtv_yuv_init in ivtv_yuv_next_free
drivers/media/pci/ivtv/ivtv-yuv.c, 1126:
	ivtv_yuv_next_free in ivtv_yuv_setup_stream_frame
drivers/media/pci/ivtv/ivtv-irq.c, 827:
	ivtv_yuv_setup_stream_frame in ivtv_irq_dec_data_req
drivers/media/pci/ivtv/ivtv-irq.c, 1013:
	ivtv_irq_dec_data_req in ivtv_irq_handler

To fix this bug, GFP_KERNEL is replaced with GFP_ATOMIC.

This bug is found by my static analysis tool DSAC.

[ Upstream commit 6c7103aa026094a4ee2c2708ec6977a6dfc5331d ]

When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS,
the counter will be incremented but the resume callback not called,
so enumeration and charging will not start properly.
To avoid that happen, disable irq on suspend and recheck on resume.

Practically this happens when the device is woken up from suspend by
plugging in usb.

[PATCH 4.9 116/222] usb: gadget: uvc: Only halt video streaming endpoint in bulk mode

[Greg Kroah-Hartman]

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

[ Upstream commit 8dbf9c7abefd5c1434a956d5c6b25e11183061a3 ]

When USB requests for video data fail to be submitted, the driver
signals a problem to the host by halting the video streaming endpoint.
This is only valid in bulk mode, as isochronous transfers have no
handshake phase and can't thus report a stall. The usb_ep_set_halt()
call returns an error when using isochronous endpoints, which we happily
ignore, but some UDCs complain in the kernel log. Fix this by only
trying to halt the endpoint in bulk mode.

[PATCH 4.9 117/222] coresight: Fix handling of sinks

[Greg Kroah-Hartman]

From: Suzuki K Poulose <suzuki.poulose@arm.com>

[ Upstream commit c71369de02b285d9da526a526d8f2affc7b17c59 ]

The coresight components could be operated either in sysfs mode or in perf
mode. For some of the components, the mode of operation doesn't matter as
they simply relay the data to the next component in the trace path. But for
sinks, they need to be able to provide the trace data back to the user.
Thus we need to make sure that "mode" is handled appropriately. e.g,
the sysfs mode could have multiple sources driving the trace data, while
perf mode doesn't allow sharing the sink.

The coresight_enable_sink() however doesn't really allow this check to
trigger as it skips the "enable_sink" callback if the component is
already enabled, irrespective of the mode. This could cause mixing
of data from different modes or even same mode (in perf), if the
sources are different. Also, if we fail to enable the sink while
enabling a path (where sink is the first component enabled),
we could end up in disabling the components in the "entire"
path which were not enabled in this trial, causing disruptions
in the existing trace paths.

[PATCH 4.9 118/222] coresight: etm4x: Configure EL2 exception level when kernel is running in HYP

[Greg Kroah-Hartman]

From: Tomasz Nowicki <tnowicki@caviumnetworks.com>

[ Upstream commit b860801e3237ec4c74cf8de0be4816996757ae5c ]

For non-VHE systems host kernel runs at EL1 and jumps to EL2 whenever
hypervisor code should be executed. In this case ETM4x driver must
restrict configuration to EL1 when it setups kernel tracing.
However, there is no separate hypervisor privilege level when VHE
is enabled, the host kernel runs at EL2.

This patch fixes configuration of TRCACATRn register for VHE systems
so that ETM_EXLEVEL_NS_HYP bit is used instead of ETM_EXLEVEL_NS_OS
to on/off kernel tracing. At the same time, it moves common code
to new helper.

[PATCH 4.9 119/222] coresight: tmc: Fix byte-address alignment for RRP

[Greg Kroah-Hartman]

From: Leo Yan <leo.yan@linaro.org>

[ Upstream commit e7753f3937610633a540f2be81be87531f96ff04 ]

>From the comment in the code, it claims the requirement for byte-address
alignment for RRP register: 'for 32-bit, 64-bit and 128-bit wide trace
memory, the four LSBs must be 0s. For 256-bit wide trace memory, the
five LSBs must be 0s'.  This isn't consistent with the program, the
program sets five LSBs as zeros for 32/64/128-bit wide trace memory and
set six LSBs zeros for 256-bit wide trace memory.

After checking with the CoreSight Trace Memory Controller technical
reference manual (ARM DDI 0461B, section 3.3.4 RAM Read Pointer
Register), it proves the comment is right and the program does wrong
setting.

This patch fixes byte-address alignment for RRP by following correct
definition in the technical reference manual.

[PATCH 4.9 120/222] misc: kgdbts: Fix restrict error

From: Laura Abbott <labbott@redhat.com>

[ Upstream commit fa0218ef733e6f247a1a3986e3eb12460064ac77 ]

kgdbts current fails when compiled with restrict:

drivers/misc/kgdbts.c: In function ‘configure_kgdbts’:
drivers/misc/kgdbts.c:1070:2: error: ‘strcpy’ source argument is the same as destination [-Werror=restrict]
  strcpy(config, opt);
  ^~~~~~~~~~~~~~~~~~~

As the error says, config is being used in both the source and destination.
Refactor the code to avoid the extra copy and put the parsing closer to
the actual location.

[PATCH 4.9 123/222] vfio/pci: Mask buggy SR-IOV VF INTx support

[Greg Kroah-Hartman]

From: Alex Williamson <alex.williamson@redhat.com>

[ Upstream commit db04264fe9bc0f2b62e036629f9afb530324b693 ]

The SR-IOV spec requires that VFs must report zero for the INTx pin
register as VFs are precluded from INTx support.  It's much easier for
the host kernel to understand whether a device is a VF and therefore
whether a non-zero pin register value is bogus than it is to do the
same in userspace.  Override the INTx count for such devices and
virtualize the pin register to provide a consistent view of the device
to the user.

As this is clearly a spec violation, warn about it to support hardware
validation, but also provide a known whitelist as it doesn't do much
good to continue complaining if the hardware vendor doesn't plan to
fix it.

Known devices with this issue: 8086:270c

[PATCH 4.9 124/222] scsi: libsas: always unregister the old device if going to discover new

[Greg Kroah-Hartman]

From: Jason Yan <yanaijie@huawei.com>

[ Upstream commit 32c850bf587f993b2620b91e5af8a64a7813f504 ]

If we went into sas_rediscover_dev() the attached_sas_addr was already insured
not to be zero. So it's unnecessary to check if the attached_sas_addr is zero.

And although if the sas address is not changed, we always have to unregister
the old device when we are going to register a new one. We cannot just leave
the device there and bring up the new.

[PATCH 4.9 129/222] EDAC: Raise the maximum number of memory controllers

[Greg Kroah-Hartman]

From: Justin Ernst <justin.ernst@hpe.com>

[ Upstream commit 6b58859419554fb824e09cfdd73151a195473cbc ]

We observe an oops in the skx_edac module during boot:

  EDAC MC0: Giving out device to module skx_edac controller Skylake Socket#0 IMC#0
  EDAC MC1: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
  EDAC MC2: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
  ...
  EDAC MC13: Giving out device to module skx_edac controller Skylake Socket#0 IMC#1
  EDAC MC14: Giving out device to module skx_edac controller Skylake Socket#1 IMC#0
  EDAC MC15: Giving out device to module skx_edac controller Skylake Socket#1 IMC#1
  Too many memory controllers: 16
  EDAC MC: Removed device 0 for skx_edac Skylake Socket#0 IMC#0

We observe there are two memory controllers per socket, with a limit
of 16. Raise the maximum number of memory controllers from 16 to 2 *
MAX_NUMNODES (1024).

[ bp: This is just a band-aid fix until we've sorted out the whole issue
  with the bus_type association and handling in EDAC and can get rid of
  this arbitrary limit. ]

[PATCH 4.9 134/222] scsi: NCR5380: Clear all unissued commands on host reset

[Greg Kroah-Hartman]

From: Hannes Reinecke <hare@suse.com>

[ Upstream commit 1aeeeed7f03c576f096eede7b0384f99a98f588c ]

When doing a host reset we should be clearing all outstanding commands, not
just the command triggering the reset.

[PATCH 4.9 135/222] scsi: NCR5380: Use DRIVER_SENSE to indicate valid sense data

[Greg Kroah-Hartman]

From: Finn Thain <fthain@telegraphics.com.au>

[ Upstream commit 070356513963be6196142acff56acc8359069fa1 ]

When sense data is valid, call set_driver_byte(cmd, DRIVER_SENSE).  Otherwise
some callers of scsi_execute() will ignore sense data.  Don't set DID_ERROR or
DID_RESET just because sense data is missing.

[PATCH 4.9 137/222] scsi: NCR5380: Dont clear busy flag when abort fails

[Greg Kroah-Hartman]

From: Finn Thain <fthain@telegraphics.com.au>

[ Upstream commit 45ddc1b24806cc8f1a09f23dd4e7b6e4a8ae36e1 ]

When NCR5380_abort() returns FAILED, the driver forgets that the target is
still busy. Hence, further commands may be sent to the target, which may fail
during selection and produce the error message, "reselection after won
arbitration?". Prevent this by leaving the busy flag set when NCR5380_abort()
fails.

    ... The reselected initiator shall then assert the BSY signal
    within a selection abort time of its most recent detection of being
    reselected; this is required for correct operation of the time-out
    procedure.

The selection abort time is only 200 us which may be insufficient time for a
printk() call. Move the diagnostics to the error paths.

[PATCH 4.9 144/222] fuse: use READ_ONCE on congestion_threshold and max_background

[Greg Kroah-Hartman]

From: Kirill Tkhai <ktkhai@virtuozzo.com>

[ Upstream commit 2a23f2b8adbe4bd584f936f7ac17a99750eed9d7 ]

Since they are of unsigned int type, it's allowed to read them
unlocked during reporting to userspace. Let's underline this fact
with READ_ONCE() macroses.

[PATCH 4.9 146/222] memfd: Use radix_tree_deref_slot_protected to avoid the warning.

[Greg Kroah-Hartman]

From: zhong jiang <zhongjiang@huawei.com>

The commit 3ce6b467b9b2 ("memfd: Fix locking when tagging pins")
introduces the following warning messages.

*WARNING: suspicious RCU usage in memfd_wait_for_pins*

It is because we still use radix_tree_deref_slot without read_rcu_lock.
We should use radix_tree_deref_slot_protected instead in the case.

This code is supposed to test for negative error codes and partial
reads, but because sizeof() is size_t (unsigned) type then negative
error codes are type promoted to high positive values and the condition
doesn't work as expected.

[PATCH 4.9 149/222] x86/atomic: Fix smp_mb__{before,after}_atomic()

[Greg Kroah-Hartman]

From: Peter Zijlstra <peterz@infradead.org>

commit 69d927bba39517d0980462efc051875b7f4db185 upstream.

Recent probing at the Linux Kernel Memory Model uncovered a
'surprise'. Strongly ordered architectures where the atomic RmW
primitive implies full memory ordering and
smp_mb__{before,after}_atomic() are a simple barrier() (such as x86)
fail for:

	*x = 1;
	atomic_inc(u);
	smp_mb__after_atomic();
	r0 = *y;

Because, while the atomic_inc() implies memory order, it
(surprisingly) does not provide a compiler barrier. This then allows
the compiler to re-order like so:

	atomic_inc(u);
	*x = 1;
	smp_mb__after_atomic();
	r0 = *y;

Which the CPU is then allowed to re-order (under TSO rules) like:

	atomic_inc(u);
	r0 = *y;
	*x = 1;

And this very much was not intended. Therefore strengthen the atomic
RmW ops to include a compiler barrier.

NOTE: atomic_{or,and,xor} and the bitops already had the compiler
barrier.

[PATCH 4.9 150/222] kprobes/x86: Prohibit probing on exception masking instructions

[Greg Kroah-Hartman]

From: Masami Hiramatsu <mhiramat@kernel.org>

commit ee6a7354a3629f9b65bc18dbe393503e9440d6f5 upstream.

Since MOV SS and POP SS instructions will delay the exceptions until the
next instruction is executed, single-stepping on it by kprobes must be
prohibited.

However, kprobes usually executes those instructions directly on trampoline
buffer (a.k.a. kprobe-booster), except for the kprobes which has
post_handler. Thus if kprobe user probes MOV SS with post_handler, it will
do single-stepping on the MOV SS.

This means it is safe that if it is used via ftrace or perf/bpf since those
don't use the post_handler.

Anyway, since the stack switching is a rare case, it is safer just
rejecting kprobes on such instructions.

[PATCH 4.9 151/222] uprobes/x86: Prohibit probing on MOV SS instruction

From: Masami Hiramatsu <mhiramat@kernel.org>

commit 13ebe18c94f5b0665c01ae7fad2717ae959f4212 upstream.

Since MOV SS and POP SS instructions will delay the exceptions until the
next instruction is executed, single-stepping on it by uprobes must be
prohibited.

uprobe already rejects probing on POP SS (0x1f), but allows probing on MOV
SS (0x8e and reg == 2).  This checks the target instruction and if it is
MOV SS or POP SS, returns -ENOTSUPP to reject probing.

[PATCH 4.9 153/222] block: introduce blk_rq_is_passthrough

[Greg Kroah-Hartman]

From: Christoph Hellwig <hch@lst.de>

commit 57292b58ddb58689e8c3b4c6eadbef10d9ca44dd upstream.

This can be used to check for fs vs non-fs requests and basically
removes all knowledge of BLOCK_PC specific from the block layer,
as well as preparing for removing the cmd_type field in struct request.

[PATCH 4.9 154/222] libata: have ata_scsi_rw_xlat() fail invalid passthrough requests

[Greg Kroah-Hartman]

From: Jens Axboe <axboe@kernel.dk>

commit 2d7271501720038381d45fb3dcbe4831228fc8cc upstream.

For passthrough requests, libata-scsi takes what the user passes in
as gospel. This can be problematic if the user fills in the CDB
incorrectly. One example of that is in request sizes. For read/write
commands, the CDB contains fields describing the transfer length of
the request. These should match with the SG_IO header fields, but
libata-scsi currently does no validation of that.

Check that the number of blocks in the CDB for passthrough requests
matches what was mapped into the request. If the CDB asks for more
data then the validated SG_IO header fields, error it.

Since SMPS10 and OTG cable detection extcon are described here, and
work to enable OTG power when an OTG cable is plugged in, we can
define OTG mode in the controller (which is disabled by default in
omap5.dtsi).

[ Upstream commit f42f7c283078ce3c1e8368b140e270755b1ae313 ]

Fix up the priority queue to not batch by owner, but by queue, so that
we allow '1 << priority' elements to be dequeued before switching to
the next priority queue.
The owner field is still used to wake up requests in round robin order
by owner to avoid single processes hogging the RPC layer by loading the
queues.

[PATCH 4.9 160/222] kvm: arm/arm64: Fix stage2_flush_memslot for 4 level page table

[Greg Kroah-Hartman]

From: Suzuki K Poulose <suzuki.poulose@arm.com>

[ Upstream commit d2db7773ba864df6b4e19643dfc54838550d8049 ]

So far we have only supported 3 level page table with fixed IPA of
40bits, where PUD is folded. With 4 level page tables, we need
to check if the PUD entry is valid or not. Fix stage2_flush_memslot()
to do this check, before walking down the table.

[PATCH 4.9 161/222] arm64/numa: Report correct memblock range for the dummy node

[Greg Kroah-Hartman]

From: Anshuman Khandual <anshuman.khandual@arm.com>

[ Upstream commit 77cfe950901e5c13aca2df6437a05f39dd9a929b ]

The dummy node ID is marked into all memory ranges on the system. So the
dummy node really extends the entire memblock.memory. Hence report correct
extent information for the dummy node using memblock range helper functions
instead of the range [0LLU, PFN_PHYS(max_pfn) - 1)].

[PATCH 4.9 162/222] ath10k: fix vdev-start timeout on error

[Greg Kroah-Hartman]

From: Ben Greear <greearb@candelatech.com>

[ Upstream commit 833fd34d743c728afe6d127ef7bee67e7d9199a8 ]

The vdev-start-response message should cause the
completion to fire, even in the error case.  Otherwise,
the user still gets no useful information and everything
is blocked until the timeout period.

Add some warning text to print out the invalid status
code to aid debugging, and propagate failure code.

[PATCH 4.9 165/222] usb: gadget: udc: fotg210-udc: Fix a sleep-in-atomic-context bug in fotg210_get_status()

[Greg Kroah-Hartman]

From: Jia-Ju Bai <baijiaju1990@gmail.com>

[ Upstream commit 2337a77c1cc86bc4e504ecf3799f947659c86026 ]

The driver may sleep in an interrupt handler.
The function call path (from bottom to top) in Linux-4.17 is:

[FUNC] fotg210_ep_queue(GFP_KERNEL)
drivers/usb/gadget/udc/fotg210-udc.c, 744:
	fotg210_ep_queue in fotg210_get_status
drivers/usb/gadget/udc/fotg210-udc.c, 768:
	fotg210_get_status in fotg210_setup_packet
drivers/usb/gadget/udc/fotg210-udc.c, 949:
	fotg210_setup_packet in fotg210_irq (interrupt handler)

To fix this bug, GFP_KERNEL is replaced with GFP_ATOMIC.
If possible, spin_unlock() and spin_lock() around fotg210_ep_queue()
can be also removed.

This bug is found by my static analysis tool DSAC.

[PATCH 4.9 172/222] powerpc/pseries: Fix DTL buffer registration

[Greg Kroah-Hartman]

From: Naveen N. Rao <naveen.n.rao@linux.vnet.ibm.com>

[ Upstream commit db787af1b8a6b4be428ee2ea7d409dafcaa4a43c ]

When CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not set, we register the DTL
buffer for a cpu when the associated file under powerpc/dtl in debugfs
is opened. When doing so, we need to set the size of the buffer being
registered in the second u32 word of the buffer. This needs to be in big
endian, but we are not doing the conversion resulting in the below error
showing up in dmesg:

	dtl_start: DTL registration for cpu 0 (hw 0) failed with -4

Fix this in the obvious manner.

[PATCH 4.9 173/222] powerpc/pseries: Fix how we iterate over the DTL entries

[Greg Kroah-Hartman]

[ Upstream commit 9258227e9dd1da8feddb07ad9702845546a581c9 ]

When CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not set, we look up dtl_idx in
the lppaca to determine the number of entries in the buffer. Since
lppaca is in big endian, we need to do an endian conversion before using
this in our calculation to determine the number of entries in the
buffer. Without this, we do not iterate over the existing entries in the
DTL buffer properly.

[PATCH 4.9 179/222] ata: ep93xx: Use proper enums for directions

Use the equivalent valued enums from the expected type so that Clang no
longer warns about a conversion.

[PATCH 4.9 180/222] media: pxa_camera: Fix check for pdev->dev.of_node

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit 44d7f1a77d8c84f8e42789b5475b74ae0e6d4758 ]

Clang warns that the address of a pointer will always evaluated as true
in a boolean context.

'pdev->dev.of_node' will always evaluate to 'true'

             ~~~~~~~~~~^~~~~~~ ~~
1 warning generated.

Judging from the rest of the kernel, it seems like this was an error and
just the value of of_node should be checked rather than the address.

[PATCH 4.9 181/222] ALSA: hda/sigmatel - Disable automute for Elo VuPoint

[Greg Kroah-Hartman]

From: Michael Pobega <mpobega@neverware.com>

[ Upstream commit d153135e93a50cdb6f1b52e238909e9965b56056 ]

The Elo VuPoint 15MX has two headphone jacks of which neither work by
default. Disabling automute allows ALSA to work normally with the
speakers & left headphone jack.

Future pin configuration changes may be required in the future to get
the right headphone jack working in tandem.

[PATCH 4.9 182/222] KVM: PPC: Book3S PR: Exiting split hack mode needs to fixup both PC and LR

[Greg Kroah-Hartman]

From: Cameron Kaiser <spectre@floodgap.com>

[ Upstream commit 1006284c5e411872333967b1970c2ca46a9e225f ]

When an OS (currently only classic Mac OS) is running in KVM-PR and makes a
linked jump from code with split hack addressing enabled into code that does
not, LR is not correctly updated and reflects the previously munged PC.

To fix this, this patch undoes the address munge when exiting split
hack mode so that code relying on LR being a proper address will now
execute. This does not affect OS X or other operating systems running
on KVM-PR.

[PATCH 4.9 186/222] brcmfmac: reduce timeout for action frame scan

[Greg Kroah-Hartman]

From: Chung-Hsien Hsu <stanley.hsu@cypress.com>

[ Upstream commit edb6d6885bef82d1eac432dbeca9fbf4ec349d7e ]

Finding a common channel to send an action frame out is required for
some action types. Since a loop with several scan retry is used to find
the channel, a short wait time could be considered for each attempt.
This patch reduces the wait time from 1500 to 450 msec for each action
frame scan.

This patch fixes the WFA p2p certification 5.1.20 failure caused by the
long action frame send time.

[PATCH 4.9 187/222] brcmfmac: fix full timeout waiting for action frame on-channel tx

[Greg Kroah-Hartman]

From: Chung-Hsien Hsu <stanley.hsu@cypress.com>

[ Upstream commit fbf07000960d9c8a13fdc17c6de0230d681c7543 ]

The driver sends an action frame down and waits for a completion signal
triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event
to continue the process. However, the action frame could be transmitted
either on the current channel or on an off channel. For the on-channel
case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when
the frame is transmitted, which make the driver always wait a full
timeout duration. This patch has the completion signal be triggered by
receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel
case.

This change fixes WFA p2p certification 5.1.19 failure.

[PATCH 4.9 188/222] clk: samsung: Use clk_hw API for calling clk framework from clk notifiers

[Greg Kroah-Hartman]

From: Marek Szyprowski <m.szyprowski@samsung.com>

[ Upstream commit 1da220e3a5d22fccda0bc8542997abc1d1741268 ]

clk_notifier_register() documentation states, that the provided notifier
callbacks associated with the notifier must not re-enter into the clk
framework by calling any top-level clk APIs. Fix this by replacing
clk_get_rate() calls with clk_hw_get_rate(), which is safe in this
context.

Running "./nfstest_delegation --runtest recall26" uncovers that
client doesn't recover the lock when we have an appending open,
where the initial open got a write delegation.

Instead of checking for the passed in open context against
the file lock's open context. Check that the state is the same.

[PATCH 4.9 194/222] x86/olpc: Fix build error with CONFIG_MFD_CS5535=m

[Greg Kroah-Hartman]

From: Borislav Petkov <bp@suse.de>

[ Upstream commit fa112cf1e8bc693d5a666b1c479a2859c8b6e0f1 ]

When building a 32-bit config which has the above MFD item as module
but OLPC_XO1_PM is enabled =y - which is bool, btw - the kernel fails
building with:

  ld: arch/x86/platform/olpc/olpc-xo1-pm.o: in function `xo1_pm_remove':
  /home/boris/kernel/linux/arch/x86/platform/olpc/olpc-xo1-pm.c:159: undefined reference to `mfd_cell_disable'

  make: *** [Makefile:1030: vmlinux] Error 1

Force MFD_CS5535 to y if OLPC_XO1_PM is enabled.

[PATCH 4.9 195/222] crypto: mxs-dcp - Fix SHA null hashes and output length

[Greg Kroah-Hartman]

From: Radu Solea <radu.solea@nxp.com>

[ Upstream commit c709eebaf5c5faa8a0f140355f9cfe67e8f7afb1 ]

DCP writes at least 32 bytes in the output buffer instead of hash length
as documented. Add intermediate buffer to prevent write out of bounds.

When requested to produce null hashes DCP fails to produce valid output.
Add software workaround to bypass hardware and return valid output.

[PATCH 4.9 196/222] crypto: mxs-dcp - Fix AES issues

From: Radu Solea <radu.solea@nxp.com>

[ Upstream commit fadd7a6e616b89c7f4f7bfa7b824f290bab32c3c ]

The DCP driver does not obey cryptlen, when doing android CTS this
results in passing to hardware input stream lengths which are not
multiple of block size.

Add a check to prevent future erroneous stream lengths from reaching the
hardware and adjust the scatterlist walking code to obey cryptlen.

Also properly copy-out the IV for chaining.

[PATCH 4.9 197/222] ACPI / SBS: Fix rare oops when removing modules

[Greg Kroah-Hartman]

From: Ronald Tschalär <ronald@innovation.ch>

[ Upstream commit 757c968c442397f1249bb775a7c8c03842e3e0c7 ]

There was a small race when removing the sbshc module where
smbus_alarm() had queued acpi_smbus_callback() for deferred execution
but it hadn't been run yet, so that when it did run hc had been freed
and the module unloaded, resulting in an invalid paging request.

A similar race existed when removing the sbs module with regards to
acpi_sbs_callback() (which is called from acpi_smbus_callback()).

We therefore need to ensure no callbacks are pending or executing before
the cleanups are done and the modules are removed.

[PATCH 4.9 198/222] iwlwifi: mvm: dont send keys when entering D3

From: Sara Sharon <sara.sharon@intel.com>

[ Upstream commit 8c7fd6a365eb5b2647b2c01918730d0a485b9f85 ]

In the past, we needed to program the keys when entering D3. This was
since we replaced the image. However, now that there is a single
image, this is no longer needed.  Note that RSC is sent separately in
a new command.  This solves issues with newer devices that support PN
offload. Since driver re-sent the keys, the PN got zeroed and the
receiver dropped the next packets, until PN caught up again.

[ Upstream commit b790c8ea5593d6dc3580adfad8e117eeb56af874 ]

Calling of_node_put() decreases the reference count of a device tree
object, and may free some data.

However, the of_phandle_args structure embedding it is passed to
reset_controller_dev.of_xlate() after that, so it may still be accessed.

Move the call to of_node_put() down to fix this.

[PATCH 4.9 202/222] bcache: recal cached_dev_sectors on detach

From: Shenghui Wang <shhuiw@foxmail.com>

[ Upstream commit 46010141da6677b81cc77f9b47f8ac62bd1cbfd3 ]

Recal cached_dev_sectors on cached_dev detached, as recal done on
cached_dev attached.

Update the cached_dev_sectors before bcache_device_detach called
as bcache_device_detach will set bcache_device->c to NULL.

These statements have been present since 2012, introduced by

then presumably without any issues, removing the always true if

[PATCH 4.9 208/222] media: isif: fix a NULL pointer dereference bug

[Greg Kroah-Hartman]

From: Wenwen Wang <wang6495@umn.edu>

[ Upstream commit a26ac6c1bed951b2066cc4b2257facd919e35c0b ]

In isif_probe(), there is a while loop to get the ISIF base address and
linearization table0 and table1 address. In the loop body, the function
platform_get_resource() is called to get the resource. If
platform_get_resource() returns NULL, the loop is terminated and the
execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the
first iteration because platform_get_resource() returns NULL and the
execution goes to 'fail_nobase_res'. Given that there is another while loop
at 'fail_nobase_res' and i equals to 0, one iteration of the second while
loop will be executed. However, the second while loop does not check the
return value of platform_get_resource(). This can cause a NULL pointer
dereference bug if the return value is a NULL pointer.

This patch avoids the above issue by adding a check in the second while
loop after the call to platform_get_resource().

[PATCH 4.9 209/222] GFS2: Flush the GFS2 delete workqueue before stopping the kernel threads

[Greg Kroah-Hartman]

From: Tim Smith <tim.smith@citrix.com>

[ Upstream commit 1eb8d7387908022951792a46fa040ad3942b3b08 ]

Flushing the workqueue can cause operations to happen which might
call gfs2_log_reserve(), or get stuck waiting for locks taken by such
operations.  gfs2_log_reserve() can io_schedule(). If this happens, it
will never wake because the only thing which can wake it is gfs2_logd()
which was already stopped.

This causes umount of a gfs2 filesystem to wedge permanently if, for
example, the umount immediately follows a large delete operation.

When this occured, the following stack trace was obtained from the
umount command

[PATCH 4.9 210/222] media: cx231xx: fix potential sign-extension overflow on large shift

[Greg Kroah-Hartman]

From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 32ae592036d7aeaabcccb2b1715373a68639a768 ]

Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set.  Fix this by casting value[3] to a u32 before
the shift.

walk_system_ram_res() expects "start, end" arguments that are inclusive,

KEXEC_BACKUP_SRC_END was previously defined as (640 * 1024UL), which is the
first address *past* the desired 0-640KB range.

Define KEXEC_BACKUP_SRC_END as (640 * 1024UL - 1) so the KEXEC_BACKUP_SRC

[PATCH 4.9 211/222] x86/kexec: Correct KEXEC_BACKUP_SRC_END off-by-one error

[Greg Kroah-Hartman]

From: Bjorn Helgaas <bhelgaas@google.com>

[ Upstream commit 51fbf14f2528a8c6401290e37f1c893a2412f1d3 ]

The only use of KEXEC_BACKUP_SRC_END is as an argument to
walk_system_ram_res():

  int crash_load_segments(struct kimage *image)
  {
    ...
    walk_system_ram_res(KEXEC_BACKUP_SRC_START, KEXEC_BACKUP_SRC_END,
                        image, determine_backup_region);

walk_system_ram_res() expects "start, end" arguments that are inclusive,
i.e., the range to be walked includes both the start and end addresses.

KEXEC_BACKUP_SRC_END was previously defined as (640 * 1024UL), which is the
first address *past* the desired 0-640KB range.

Define KEXEC_BACKUP_SRC_END as (640 * 1024UL - 1) so the KEXEC_BACKUP_SRC
region is [0-0x9ffff], not [0-0xa0000].

[PATCH 4.9 212/222] gpio: syscon: Fix possible NULL ptr usage

[Greg Kroah-Hartman]

From: Marek Vasut <marex@denx.de>

[ Upstream commit 70728c29465bc4bfa7a8c14304771eab77e923c7 ]

The priv->data->set can be NULL while flags contains GPIO_SYSCON_FEAT_OUT
and chip->set is valid pointer. This happens in case the controller uses
the default GPIO setter. Always use chip->set to access the setter to avoid
possible NULL pointer dereferencing.

[PATCH 4.9 213/222] spi: spidev: Fix OF tree warning logic

[Greg Kroah-Hartman]

From: Trent Piepho <tpiepho@impinj.com>

[ Upstream commit 605b3bec73cbd74b4ac937b580cd0b47d1300484 ]

spidev will make a big fuss if a device tree node binds a device by
using "spidev" as the node's compatible property.

However, the logic for this isn't looking for "spidev" in the
compatible, but rather checking that the device is NOT compatible with
spidev's list of devices.

This causes a false positive if a device not named "rohm,dh2228fv", etc.
binds to spidev, even if a means other than putting "spidev" in the
device tree was used.  E.g., the sysfs driver_override attribute.

From: Timothy E Baldwin <T.E.Baldwin99@members.leeds.ac.uk>

On at least x86 and ARM64, and as documented in the ptrace man page
a skipped system call will still cause a syscall exit ptrace stop.

Previous to this commit 32-bit ARM did not, resulting in strace
being confused when seccomp skips system calls.

This change also impacts programs that use ptrace to skip system calls.

The three INA3221_CONFIG_MODE macros are not correctly defined here.
The MODE3-1 bits are located at BIT 2-0 according to the datasheet.

So this patch just fixes them by shifting all of them with a correct
offset. However, this isn't a crital bug fix as the driver does not
use any of them at this point.

[PATCH 4.9 222/222] arm64: uaccess: Ensure PAN is re-enabled after unhandled uaccess fault

[Greg Kroah-Hartman]

From: Pavel Tatashin <pasha.tatashin@soleen.com>

commit 94bb804e1e6f0a9a77acf20d7c70ea141c6c821e upstream.

A number of our uaccess routines ('__arch_clear_user()' and
'__arch_copy_{in,from,to}_user()') fail to re-enable PAN if they
encounter an unhandled fault whilst accessing userspace.

For CPUs implementing both hardware PAN and UAO, this bug has no effect
when both extensions are in use by the kernel.

For CPUs implementing hardware PAN but not UAO, this means that a kernel
using hardware PAN may execute portions of code with PAN inadvertently
disabled, opening us up to potential security vulnerabilities that rely
on userspace access from within the kernel which would usually be
prevented by this mechanism. In other words, parts of the kernel run the
same way as they would on a CPU without PAN implemented/emulated at all.

For CPUs not implementing hardware PAN and instead relying on software
emulation via 'CONFIG_ARM64_SW_TTBR0_PAN=y', the impact is unfortunately
much worse. Calling 'schedule()' with software PAN disabled means that
the next task will execute in the kernel using the page-table and ASID
of the previous process even after 'switch_mm()', since the actual
hardware switch is deferred until return to userspace. At this point, or
if there is a intermediate call to 'uaccess_enable()', the page-table
and ASID of the new process are installed. Sadly, due to the changes
introduced by KPTI, this is not an atomic operation and there is a very
small window (two instructions) where the CPU is configured with the
page-table of the old task and the ASID of the new task; a speculative
access in this state is disastrous because it would corrupt the TLB
entries for the new task with mappings from the previous address space.

As Pavel explains:

  | I was able to reproduce memory corruption problem on Broadcom's SoC
  | ARMv8-A like this:
  |
  | Enable software perf-events with PERF_SAMPLE_CALLCHAIN so userland's
  | stack is accessed and copied.
  |
  | The test program performed the following on every CPU and forking
  | many processes:
  |
  |	unsigned long *map = mmap(NULL, PAGE_SIZE, PROT_READ|PROT_WRITE,
  |				  MAP_SHARED | MAP_ANONYMOUS, -1, 0);
  |	map[0] = getpid();
  |	sched_yield();
  |	if (map[0] != getpid()) {
  |		fprintf(stderr, "Corruption detected!");
  |	}
  |	munmap(map, PAGE_SIZE);
  |
  | From time to time I was getting map[0] to contain pid for a
  | different process.

Ensure that PAN is re-enabled when returning after an unhandled user
fault from our uaccess routines.
