4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonathan Toppins <jtoppins@redhat.com>
commit 75dddef32514f7aa58930bde6a1263253bc3d4ba upstream.
The RDMA subsystem can generate several thousand of these messages per
second eventually leading to a kernel crash. Ratelimit these messages
to prevent this crash.
Doug said:
"I've been carrying a version of this for several kernel versions. I
don't remember when they started, but we have one (and only one) class
of machines: Dell PE R730xd, that generate these errors. When it
happens, without a rate limit, we get rcu timeouts and kernel oopses.
With the rate limit, we just get a lot of annoying kernel messages but
the machine continues on, recovers, and eventually the memory
operations all succeed"
And:
"> Well... why are all these EBUSY's occurring? It sounds inefficient
> (at least) but if it is expected, normal and unavoidable then
> perhaps we should just remove that message altogether?
I don't have an answer to that question. To be honest, I haven't
looked real hard. We never had this at all, then it started out of the
blue, but only on our Dell 730xd machines (and it hits all of them),
but no other classes or brands of machines. And we have our 730xd
machines loaded up with different brands and models of cards (for
instance one dedicated to mlx4 hardware, one for qib, one for mlx5, an
ocrdma/cxgb4 combo, etc), so the fact that it hit all of the machines
meant it wasn't tied to any particular brand/model of RDMA hardware.
To me, it always smelled of a hardware oddity specific to maybe the
CPUs or mainboard chipsets in these machines, so given that I'm not an
mm expert anyway, I never chased it down.
A few other relevant details: it showed up somewhere around 4.8/4.9 or
thereabouts. It never happened before, but the prinkt has been there
since the 3.18 days, so possibly the test to trigger this message was
changed, or something else in the allocator changed such that the
situation started happening on these machines?
And, like I said, it is specific to our 730xd machines (but they are
all identical, so that could mean it's something like their specific
ram configuration is causing the allocator to hit this on these
machine but not on other machines in the cluster, I don't want to say
it's necessarily the model of chipset or CPU, there are other bits of
identicalness between these machines)"

commit d041353dc98a6339182cd6f628b4c8f111278cb3 upstream.

The problem is that shmem_unused_huge_shrink() moves entries from the
global sbinfo->shrinklist to its local lists and then releases the
spinlock. However, a parallel shmem_setattr() could access one of these
entries directly and add it back to the global shrinklist if it is
removed, with the spinlock held.
The logic itself looks solid since an entry could be either in a local
list or the global list, otherwise it is removed from one of them by
list_del_init(). So probably the race condition is that, one CPU is in
the middle of INIT_LIST_HEAD() but the other CPU calls list_empty()
which returns true too early then the following list_add_tail() sees a
corrupted entry.
list_empty_careful() is designed to fix this situation.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mel Gorman <mgorman@suse.de>
commit 48fb6f4db940e92cfb16cd878cddd59ea6120d06 upstream.
Commit 65d8fc777f6d ("futex: Remove requirement for lock_page() in
get_futex_key()") removed an unnecessary lock_page() with the
side-effect that page->mapping needed to be treated very carefully.
Two defensive warnings were added in case any assumption was missed and
the first warning assumed a correct application would not alter a
mapping backing a futex key. Since merging, it has not triggered for
any unexpected case but Mark Rutland reported the following bug
triggering due to the first warning.
kernel BUG at kernel/futex.c:679!
Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
Modules linked in:
CPU: 0 PID: 3695 Comm: syz-executor1 Not tainted 4.13.0-rc3-00020-g307fec773ba3 #3

pc : [<ffff00000821ac14>] lr : [<ffff00000821ac14>] pstate: 80000145
The fact that it's a bug instead of a warning was due to an unrelated
arm64 problem, but the warning itself triggered because the underlying
mapping changed.
This is an application issue but from a kernel perspective it's a
recoverable situation and the warning is unnecessary so this patch
removes the warning. The warning may potentially be triggered with the
following test program from Mark although it may be necessary to adjust
NR_FUTEX_THREADS to be a value smaller than the number of CPUs in the
system.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Max Filippov <jcmvbkbc@gmail.com>
commit 6d0f581d1768d3eaba15776e7dd1fdfec10cfe36 upstream.
Currently building kernel for xtensa core with aliasing WT cache fails
with the following messages:
mm/memory.c:2152: undefined reference to `flush_dcache_page'
mm/memory.c:2332: undefined reference to `local_flush_cache_page'
mm/memory.c:1919: undefined reference to `local_flush_cache_range'
mm/memory.c:4179: undefined reference to `copy_to_user_page'
mm/memory.c:4183: undefined reference to `copy_from_user_page'
This happens because implementation of these functions is only compiled
when data cache is WB, which looks wrong: even when data cache doesn't
need flushing it still needs invalidation. The functions like
__flush_[invalidate_]dcache_* are correctly defined for both WB and WT
caches (and even if they weren't that'd still be ok, just slower).
Fix this by providing the same implementation of the above functions for
both WB and WT cache.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Max Filippov <jcmvbkbc@gmail.com>
commit 7f81e55c737a8fa82c71f290945d729a4902f8d2 upstream.
csum_partial and csum_partial_copy_generic are defined unconditionally
and are available even when CONFIG_NET is disabled. They are used not
only by the network drivers, but also by scsi and media.
Don't limit these functions export by CONFIG_NET.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jan Kara <jack@suse.cz>
commit ea7bd56fa309d10a41b1041827a63c0746c47554 upstream.
The bio describing discard operation is allocated by
__blkdev_issue_discard() which returns us a reference to it. That
reference is never released and thus we leak this bio. Drop the bio
reference once it completes in xlog_discard_endio().

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gregory CLEMENT <gregory.clement@free-electrons.com>
commit 6b67c3906cd74d88da4f6717b4b294bd52fce56a upstream.
On the south bridge we have pin from to 29, so it gives 30 pins (and not
29).
Without this patch the kernel complain with the following traces:

From: Boris Brezillon <boris.brezillon@free-electrons.com>
commit 3aa0907675a38498d8f2d343e94207ad28a117cf upstream.
PMECC caps extraction from old DT bindings is broken, thus leading to
erroneous EL registers offset, which in turn make HW ECC unusable on
sama5d2 when old bindings are in use.
Passing the NAND dev node instead of the NFC node to of_match_node()
solves the problem.

commit a11bf5ed951f8900d244d09eb03a888b59c7fc82 upstream.
Some ONFI NANDs do not support the SET/GET FEATURES commands, which,
according to the spec, is perfectly valid.
On these NANDs we can't set a specific timing mode using the "timing
mode" feature, and we should assume the NAND does not require any setup
to enter a specific timing mode.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Varun Prakash <varun@chelsio.com>
commit ea8dc5b4cd2195ee582cae28afa4164c6dea1738 upstream.
On receiving text request iscsi-target allocates buffer for
payload in iscsit_handle_text_cmd() and assigns buffer pointer
to cmd->text_in_ptr, this buffer is currently freed in
iscsit_release_cmd(), if iscsi-target sets 'C' bit in text
response then it will receive another text request from the
initiator with ttt != 0xffffffff in this case iscsi-target
will find cmd using itt and call iscsit_setup_text_cmd()
which will set cmd->text_in_ptr to NULL without freeing
previously allocated buffer.
This patch fixes this issue by calling kfree(cmd->text_in_ptr)
in iscsit_setup_text_cmd() before assigning NULL to it.
For the first text request cmd->text_in_ptr is NULL as
cmd is memset to 0 in iscsit_allocate_cmd().

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Bellinger <nab@linux-iscsi.org>
commit 978d13d60c34818a41fc35962602bdfa5c03f214 upstream.
This patch fixes a bug associated with iscsit_reset_np_thread()
that can occur during parallel configfs rmdir of a single iscsi_np
used across multiple iscsi-target instances, that would result in
hung task(s) similar to below where configfs rmdir process context
was blocked indefinately waiting for iscsi_np->np_restart_comp
to finish:
[ 6726.112076] INFO: task dcp_proxy_node_:15550 blocked for more than 120 seconds.

It would happen because each iscsit_reset_np_thread() sets state
to ISCSI_NP_THREAD_RESET, sends SIGINT, and then blocks waiting
for completion on iscsi_np->np_restart_comp.
However, if iscsi_np was active processing a login request and
more than a single iscsit_reset_np_thread() caller to the same
iscsi_np was blocked on iscsi_np->np_restart_comp, iscsi_np
kthread process context in __iscsi_target_login_thread() would
flush pending signals and only perform a single completion of
np->np_restart_comp before going back to sleep within transport
specific iscsit_transport->iscsi_accept_np code.
To address this bug, add a iscsi_np->np_reset_count and update
__iscsi_target_login_thread() to keep completing np->np_restart_comp
until ->np_reset_count has reached zero.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alan Stern <stern@rowland.harvard.edu>
commit 8b52291a0743fc4db4a7495c846a6f31ee84d282 upstream.
Christoph Hellwig says that since version 4.12, the kernel switched to
using blk-mq by default. The old code used a softirq for handling
request completions, but blk-mq can handle completions in the caller's
context. This may cause a problem for usb-storage, because it invokes
the ->scsi_done callback while holding the host lock, and the
completion routine sometimes tries to acquire the same lock (when
running the error handler, for example).
The consequence is that the existing code will sometimes deadlock upon
error completion of a SCSI command (with a lockdep warning).
This is easy enough to fix, since usb-storage doesn't really need to
hold the host lock while the callback runs. It was simpler to write
it that way, but moving the call outside the locked region is pretty
easy and there's no downside. That's what this patch does.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Bellinger <nab@linux-iscsi.org>
commit 6f48655facfd7f7ccfe6d252ac0fe319ab02e4dd upstream.
This patch fixes a generate_node_acls = 1 + cache_dynamic_acls = 0
regression, that was introduced by
commit 01d4d673558985d9a118e1e05026633c3e2ade9b
Author: Nicholas Bellinger <nab@linux-iscsi.org>
Date: Wed Dec 7 12:55:54 2016 -0800
which originally had the proper list_del_init() usage, but was
dropped during list review as it was thought unnecessary by HCH.
However, list_del_init() usage is required during the special
generate_node_acls = 1 + cache_dynamic_acls = 0 case when
transport_free_session() does a list_del(&se_nacl->acl_list),
followed by target_complete_nacl() doing the same thing.
This was manifesting as a general protection fault as reported

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mateusz Jurczyk <mjurczyk@google.com>
commit 68227c03cba84a24faf8a7277d2b1a03c8959c2c upstream.
Before the patch, the flock flag could remain uninitialized for the
lifespan of the fuse_file allocation. Unless set to true in
fuse_file_flock(), it would remain in an indeterminate state until read in
an if statement in fuse_release_common(). This could consequently lead to
taking an unexpected branch in the code.
The bug was discovered by a runtime instrumentation designed to detect use
of uninitialized memory in the kernel.

At least the Acer Iconia Tab8 / aka W1-810 uses 1MiHz instead of
1MHz for one of its busses, fix this up to 1MHz instead of failing
the probe of that bus.
This fixes the accelerometer on the Acer Iconia Tab8 not working.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miquel Raynal <miquel.raynal@free-electrons.com>
commit f7f8c1756e9a5f1258a7cc6b663f8451b724900f upstream.
When using soft ecc, if no ooblayout is given, the core automatically
uses one of the nand_ooblayout_{sp,lp}*() functions to determine the
layout inside the out of band data.
Until kernel version 4.6, struct nand_ecclayout was used for that
purpose. During the migration from 4.6 to 4.7, an error shown up in the
small page layout, in the case oob section is only 8 bytes long.
The layout was using three bytes (0, 1, 2) for ecc, two bytes (3, 4)
as free bytes, one byte (5) for bad block marker and finally
two bytes (6, 7) as free bytes, as shown there:
[linux-4.6] drivers/mtd/nand/nand_base.c:52
static struct nand_ecclayout nand_oob_8 = {
.eccbytes = 3,
.eccpos = {0, 1, 2},
.oobfree = {
{.offset = 3,
.length = 2},
{.offset = 6,
.length = 2} }
};
This fixes the current implementation which is incoherent. It
references bit 3 at the same time as an ecc byte and a free byte.
Furthermore, it is clear with the previous implementation that there
is only one ecc section with 8 bytes oob sections. We shall return
-ERANGE in the nand_ooblayout_ecc_sp() function when asked for the
second section.

From: Lucas Stach <l.stach@pengutronix.de>
commit d630213f2a47933e1037909273a20023ba3e598d upstream.
The output node of the TC358767 is only used if another bridge is chained
behind it. Panels attached to the TC358767 can be detected using the usual
DP AUX probing. This restores the old behavior of ignoring the output if
no endpoint is found.

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>
commit 5279fc7724ae3a82c9cfe5b09c1fb07ff0e41056 upstream.
bdw_load_gamma_lut is writing beyond the array to the maximum value.
The intend of the function is to clamp values > 1 to 1, so write
the intended color to the max register.
This fixes the following KASAN warning:

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bin Liu <b-liu@ti.com>
commit 45d73860530a14c608f410b91c6c341777bfa85d upstream.
commit 68fe05e2a451 ("usb: musb: fix tx fifo flush handling") drops the
1ms delay trying to solve the long disconnect time issue when
application queued many tx urbs. However, the 1ms delay is needed for
some use cases, for example, without the delay, reconnecting AR9271 WIFI
dongle no longer works if the connection is dropped from the AP.
So let's add back the 1ms delay in musb_h_tx_flush_fifo(), and solve the
long disconnect time problem with a separate patch for
usb_hcd_flush_endpoint().

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
commit cd5a6a4fdaba150089af2afc220eae0fef74878a upstream.
Make usb_hc_died() clear the HCD_FLAG_RH_RUNNING flag for the shared
HCD and set HCD_FLAG_DEAD for it, in analogy with what is done for
the primary one.
Among other thigs, this prevents check_root_hub_suspended() from
returning -EBUSY for dead HCDs which helps to work around system
suspend issues in some situations.
This actually fixes occasional suspend failures on one of my test
machines.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 105967ad68d2eb1a041bc041f9cf96af2a653b65 upstream.
gcc-7 points out an older regression:
drivers/staging/iio/resolver/ad2s1210.c: In function 'ad2s1210_read_raw':
drivers/staging/iio/resolver/ad2s1210.c:515:42: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]
The original code had 'unsigned short' here, but incorrectly got
converted to 'bool'. This reverts the regression and uses a normal
type instead.

This patch enables adc engine at initialization time and waits
for the initial sequence completion before enabling adc channels.
Without this code adc channels are not functional and shows
zeros for all connected channels.
Tested on mellanox msn platform.

From: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com>
commit a7b8829d242b1a58107e9c02b09e93aec446d55c upstream.
Add SPI Serial Interface Mode (SIM) register information
in st_sensor_settings look up table to support devices
(like LSM303AGR accel sensor) that allow just SPI-3wire
communication mode. SIM mode has to be configured before any
other operation since it is not enabled by default and the driver
is not able to read without that configuration
Whilst a fairly substantial patch, the actual logic is simple and it
is better to have the generic fix than a band aid.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
commit e59e18989c68a8d7941005f81ad6abc4ca682de0 upstream.
After probe we would put the device in normal mode, after a runtime
suspend-resume we would put it back in normal mode. But for a regular
suspend-resume we would only put it back in normal mode if triggers
or events have been requested. This is not consistent and breaks
reading raw values after a suspend-resume.
This commit changes the regular resume path to also unconditionally put
the device back in normal mode, fixing reading of raw values not working
after a regular suspend-resume cycle.

From: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com>
commit add6e6ab3ee0e237822e0951476d3df039b49ec8 upstream.
Set multiread variable to false for LPS22HB pressure sensor since
it is already enabled in CTRL_REG2. Previous configuration does not
cause any issue in I2C communication since SUB Msb has no meaning
whereas it breaks register address in SPI communication

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Akinobu Mita <akinobu.mita@gmail.com>
commit a3507e48d3f99a93a3056a34a5365f310434570f upstream.
The TSL2563 driver provides three iio channels, two of which are raw ADC
channels (channel 0 and channel 1) in the device and the remaining one
is calculated by the two. The ADC channel 0 only supports programmable
interrupt with threshold settings and this driver supports the event but
the generated event code does not contain the corresponding iio channel
type.
This is going to change userspace ABI. Hopefully fixing this to be
what it should always have been won't break any userspace code.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdegoede@redhat.com>
commit 631b010abc5b57009c6a8328f51492665f6ef310 upstream.
Inheriting the ADC BIAS current settings from the BIOS instead of
hardcoding then causes the AXP288 to disable charging (I think it
mis-detects an overheated battery) on at least one model tablet.
So lets go back to hard coding the values, this reverts
commit fa2849e9649b ("iio: adc: axp288: Drop bogus
AXP288_ADC_TS_PIN_CTRL register modifications"), fixing charging not
working on the model tablet in question.
The exact cause is not fully understood, hence the revert to a known working
state.

From: Ian Abbott <abbotti@mev.co.uk>
commit cef988642cdac44e910a27cb6e8166c96f86a0df upstream.
Comedi's read and write file operation handlers (`comedi_read()` and
`comedi_write()`) currently call `copy_to_user()` or `copy_from_user()`
whilst in the `TASK_INTERRUPTIBLE` state, which falls foul of the
`might_fault()` checks when enabled. Fix it by setting the current task
state back to `TASK_RUNNING` a bit earlier before calling these
functions.

Similar to commit d595259fbb7a ("usb-storage: Add ignore-residue quirk for
Initio INIC-3619") for INIC-3169 in unusual_devs.h but INIC-3069 already
present in unusual_uas.h. Both in same controller IC family.
Issue is that MakeMKV fails during key exchange with installed bluray drive
with following error:

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luis R. Rodriguez <mcgrof@kernel.org>
commit e44565f62a72064e686f7a852137595ec94d78f2 upstream.
The firmware cache mechanism serves two purposes, the secondary purpose is
not well documented nor understood. This fixes a regression with the
secondary purpose of the firmware cache mechanism: batched requests on
successful lookups. Without this fix *any* time a batched request is
triggered, secondary requests for which the batched request mechanism
was designed for will seem to last forver and seem to never return.
This issue is present for all kernel builds possible, and a hard reset
is required.
The firmware cache is used for:
1) Addressing races with file lookups during the suspend/resume cycle
by keeping firmware in memory during the suspend/resume cycle
2) Batched requests for the same file rely only on work from the first file
lookup, which keeps the firmware in memory until the last
release_firmware() is called
Batched requests *only* take effect if secondary requests come in prior to
the first user calling release_firmware(). The devres name used for the
internal firmware cache is used as a hint other pending requests are
ongoing, the firmware buffer data is kept in memory until the last user of
the buffer calls release_firmware(), therefore serializing requests and
delaying the release until all requests are done.
Batched requests wait for a wakup or signal so we can rely on the first file
fetch to write to the pending secondary requests. Commit 5b029624948d
("firmware: do not use fw_lock for fw_state protection") ported the firmware
API to use swait, and in doing so failed to convert complete_all() to
swake_up_all() -- it used swake_up(), loosing the ability for *some* batched
requests to take effect.
We *could* fix this by just using swake_up_all() *but* swait is now known
to be very special use case, so its best to just move away from it. So we
just go back to using completions as before commit 5b029624948d ("firmware:
do not use fw_lock for fw_state protection") given this was using
complete_all().
Without this fix it has been reported plugging in two Intel 6260 Wifi cards
on a system will end up enumerating the two devices only 50% of the time
[0]. The ported swake_up() should have actually handled the case with two
devices, however, *if more than two cards are used* the swake_up() would
not have sufficed. This change is only part of the required fixes for
batched requests. Another fix is provided in the next patch.
This particular change should fix the cases where more than three requests
with the same firmware name is used, otherwise batched requests will wait
for MAX_SCHEDULE_TIMEOUT and just timeout eventually.
Below is a summary of tests triggering batched requests on different
kernel builds.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luis R. Rodriguez <mcgrof@kernel.org>
commit 90d41e74a9c36a84e2efbd2a5b8d79299feee6fa upstream.
Fix batched requests from waiting forever on failure.
The firmware API batched requests feature has been broken since the API call
request_firmware_direct() was introduced on commit bba3a87e982ad ("firmware:
Introduce request_firmware_direct()"), added on v3.14 *iff* the firmware
being requested was not present in *certain kernel builds* [0].
When no firmware is found the worker which goes on to finish never informs
waiters queued up of this, so any batched request will stall in what seems
to be forever (MAX_SCHEDULE_TIMEOUT). Sadly, a reboot will also stall, as
the reboot notifier was only designed to kill custom fallback workers. The
issue seems to the user as a type of soft lockup, what *actually* happens
underneath the hood is a wait call which never completes as we failed to
issue a completion on error.
For device drivers with optional firmware schemes (ie, Intel iwlwifi, or
Netronome -- even though it uses request_firmware() and not
request_firmware_direct()), this could mean that when you boot a system with
multiple cards the firmware will seem to never load on the system, or that
the card is just not responsive even the driver initialization. Due to
differences in scheduling possible this should not always trigger --
one would need to to ensure that multiple requests are in place at the
right time for this to work, also release_firmware() must not be called
prior to any other incoming request. The complexity may not be worth
supporting batched requests in the future given the wait mechanism is
only used also for the fallback mechanism. We'll keep it for now and
just fix it.
Its reported that at least with the Intel WiFi cards on one system this
issue was creeping up 50% of the boots [0].

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luis R. Rodriguez <mcgrof@kernel.org>
commit 260d9f2fc5655a2552701cdd0b909c4466732f19 upstream.
Commit 0cb64249ca500 ("firmware_loader: abort request if wait_for_completion
is interrupted") added via 4.0 added support to abort the fallback mechanism
when a signal was detected and wait_for_completion_interruptible() returned
-ERESTARTSYS -- for instance when a user hits CTRL-C. The abort was overly
*too* effective.
When a child process terminates (successful or not) the signal SIGCHLD can
be sent to the parent process which ran the child in the background and
later triggered a sync request for firmware through a sysfs interface which
relies on the fallback mechanism. This signal in turn can be recieved by the
interruptible wait we constructed on firmware_class and detects it as an
abort *before* userspace could get a chance to write the firmware. Upon
failure -EAGAIN is returned, so userspace is also kept in the dark about
exactly what happened.
We can reproduce the issue with the fw_fallback.sh selftest:
Before this patch:
$ sudo tools/testing/selftests/firmware/fw_fallback.sh
...
tools/testing/selftests/firmware/fw_fallback.sh: error - sync firmware request cancelled due to SIGCHLD
After this patch:
$ sudo tools/testing/selftests/firmware/fw_fallback.sh
...
tools/testing/selftests/firmware/fw_fallback.sh: SIGCHLD on sync ignored as expected
Fix this by making the wait killable -- only killable by SIGKILL (kill -9).
We loose the ability to allow userspace to cancel a write with CTRL-C
(SIGINT), however its been decided the compromise to require SIGKILL is
worth the gains.
Chances of this issue occuring are low due to the number of drivers upstream
exclusively relying on the fallback mechanism for firmware (2 drivers),
however this is observed in the field with custom drivers with sysfs
triggers to load firmware. Only distributions relying on the fallback
mechanism are impacted as well. An example reported issue was on Android,
as follows:
1) Android init (pid=1) fork()s (say pid=42) [this child process is totally
unrelated to firmware loading, it could be sleep 2; for all we care ]
2) Android init (pid=1) does a write() on a (driver custom) sysfs file which
ends up calling request_firmware() kernel side
3) The firmware loading fallback mechanism is used, the request is sent to
userspace and pid 1 waits in the kernel on wait_*
4) before firmware loading completes pid 42 dies (for any reason, even
normal termination)
5) Kernel delivers SIGCHLD to pid=1 to tell it a child has died, which
causes -ERESTARTSYS to be returned from wait_*
6) The kernel's wait aborts and return -EAGAIN for the
request_firmware() caller.

commit d4acf3650c7c968f46ad932b9a25d1cc24cf4998 upstream.
The blk_mq_delay_kick_requeue_list() function is used by the device
mapper and only by the device mapper to rerun the queue and requeue
list after a delay. This function is called once per request that
gets requeued. Modify this function such that the queue is run once
per path change event instead of once per request that is requeued.

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
commit aca5b9ebd096039657417c321a9252c696b359c2 upstream.
According to the gadget.h, a "complete" function will always be called
with interrupts disabled. However, sometimes usb3_request_done() function
is called with interrupts enabled. So, this function should be held
by spin_lock_irqsave() to disable interruption. Also, this driver has
to call spin_unlock() to avoid spinlock recursion by this driver before
calling usb_gadget_giveback_request().

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>
commit 2acecd58969897795cf015c9057ebd349a3fda8a upstream.
The latest HW manual (Rev.0.55) shows us this UGCTRL2.VBUSSEL bit.
If the bit sets to 1, the VBUS drive is controlled by phy related
registers (called "UCOM Registers" on the manual). Since R-Car Gen3
environment will control VBUS by phy-rcar-gen3-usb2 driver,
the UGCTRL2.VBUSSEL bit should be set to 1. So, this patch fixes
the register's value. Otherwise, even if the ID pin indicates to
peripheral, the R-Car will output USBn_PWEN to 1 when a host driver
is running.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alan Stern <stern@rowland.harvard.edu>
commit 94c43b9897abf4ea366ed4dba027494e080c7050 upstream.
Some buggy USB disk adapters disconnect and reconnect multiple times
during the enumeration procedure. This may lead to a device
connecting at full speed instead of high speed, because when the USB
stack sees that a device isn't able to enumerate at high speed, it
tries to hand the connection over to a full-speed companion
controller.
The logic for doing this is careful to check that the device is still
connected. But this check is inadequate if the device disconnects and
reconnects before the check is done. The symptom is that a device
works, but much more slowly than it is capable of operating.
The situation was made worse recently by commit 22547c4cc4fe ("usb:
hub: Wait for connection to be reestablished after port reset"), which
increases the delay following a reset before a disconnect is
recognized, thus giving the device more time to reconnect.
This patch makes the check more robust. If the device was
disconnected at any time during enumeration, we will now skip the
full-speed handover.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bin Liu <b-liu@ti.com>
commit 2eac13624364db5b5e1666ae0bb3a4d36bc56b6e upstream.
While unlink an urb, if the urb has been programmed in the controller,
the controller driver might do some hw related actions to tear down the
urb.
Currently usb_hcd_flush_endpoint() passes each urb from the head of the
endpoint's urb_list to the controller driver, which could make the
controller driver think each urb has been programmed and take the
unnecessary actions for each urb.
This patch changes the behavior in usb_hcd_flush_endpoint() to pass the
urbs from the tail of the list, to avoid any unnecessary actions in an
controller driver.

Moshi USB to Ethernet Adapter internally uses a Genesys Logic hub to
connect to Realtek r8153.
The Realtek r8153 ethernet does not work on the internal hub, no-lpm quirk
can make it work.
Since another r8153 dongle at my hand does not have the issue, so add
the quirk to the Genesys Logic hub instead.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sandeep Singh <sandeep.singh@amd.com>
commit e788787ef4f9c24aafefc480a8da5f92b914e5e6 upstream.
Certain HP keyboards would keep inputting a character automatically which
is the wake-up key after S3 resume
On some AMD platforms USB host fails to respond (by holding resume-K) to
USB device (an HP keyboard) resume request within 1ms (TURSM) and ensures
that resume is signaled for at least 20 ms (TDRSMDN), which is defined in
USB 2.0 spec. The result is that the keyboard is out of function.
In SNPS USB design, the host responds to the resume request only after
system gets back to S0 and the host gets to functional after the internal
HW restore operation that is more than 1 second after the initial resume
request from the USB device.
As a workaround for specific keyboard ID(HP Keyboards), applying port reset
after resume when the keyboard is plugged in.

This causes pinfo->smbus_dev to be wrongly set to NULL on systems with
the ATI chipset that this function checks for first.

Ugh, for such a "simple" quirk, this has gone through so many different
iterations, all of which seem broken :(
Sandeep, can you fix this up and send a follow-on patch to us and the
linux-usb mailing list so we can get it fixed up properly?

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Hellwig <hch@lst.de>
commit b014e96d1abbd67404bbe2018937b46466299e9e upstream.
Every method in struct device_driver or structures derived from it like
struct pci_driver MUST provide exclusion vs the driver's ->remove() method,
usually by using device_lock().
Protect use of pci_error_handlers->reset_notify() by holding the device
lock while calling it.
Note:
- pci_dev_lock() calls device_lock() in addition to blocking user-space
config accesses.
- pci_err_handlers->reset_notify() is used inside
pci_dev_save_and_disable() and pci_dev_restore(). We could hold the
device lock directly in pci_reset_notify(), but we expand the region
since we have several calls following each other.
Without this, ->reset_notify() may race with ->remove() calls, which can be
easily triggered in NVMe.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <marc.zyngier@arm.com>
commit a477b9cd37aa81a490dfa3265b7ff4f2c5a92463 upstream.
The implementation of PCI workarounds may require that the device is reset
from its probe function. This implies that the PCI device lock is already
held, and makes calling pci_reset_function() impossible (since it will
itself try to take that lock).
Add pci_reset_function_locked(), which is the equivalent of
pci_reset_function(), except that it requires the PCI device lock to be
already held by the caller.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <marc.zyngier@arm.com>
commit 8466489ef5ba48272ba4fa4ea9f8f403306de4c7 upstream.
The Renesas uPD72020x XHCI controller seems to suffer from a really
annoying bug, where it may retain some of its DMA programming across a XHCI
reset, and despite the driver correctly programming new DMA addresses.
This is visible if the device has been using 64-bit DMA addresses, and is
then switched to using 32-bit DMA addresses. The top 32 bits of the
address (now zero) are ignored are replaced by the 32 bits from the
*previous* programming. Sticking with 64-bit DMA always works, but doesn't
seem very appropriate.
A PCI reset of the device restores the normal functionality, which is done
at probe time. Unfortunately, this has to be done before any quirk has
been discovered, hence the intrusive nature of the fix.

commit d466d3c1217406b14b834335b5b4b33c0d45bd09 upstream.
In order to select the alternate voltage reference pair (VALTH/VALTL), the
right value for the REFSEL field in the ADCx_CFG register is "01", leading
to 0x800 as register mask. See section 8.2.6.4 in the reference manual[1].

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Hellwig <hch@lst.de>
commit 8a9d6e964d318533ba3d2901ce153ba317c99a89 upstream.
The blocklayout code does not compile cleanly for a 32-bit sector_t,
and also has no reliable checks for devices sizes, which makes it
unsafe to use with a kernel that doesn't support large block devices.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Icenowy Zheng <icenowy@aosc.io>
commit d81ece747d8727bb8b1cfc9a20dbe62f09a4e35a upstream.
The PH16 pin has a function with mux id 0x5, which is the DET pin of the
"sim" (smart card reader) IP block.
This function is missing in old versions of A10/A20 SoCs' datasheets and
user manuals, so it's also missing in the old drivers. The newest A10
Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and
it's discovered during implementing R40 pinctrl driver.
Add it to the driver. As we now merged A20 pinctrl driver to the A10
one, we need to only fix the A10 driver now.

That happened after 4.12, so I think for stable the same change should
be applied in drivers/pinctrl/sunxi/pinctrl-sun7i-a20.c.

From: Masahiro Yamada <yamada.masahiro@socionext.com>
commit 9592bc256d50481dfcdba93890e576a728fb373c upstream.
The pingroups dump of debugfs hits WARN_ON() in pinctrl_groups_show().
Filling non-existing ports with '-1' turned out a bad idea.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <yamada.masahiro@socionext.com>
commit 1bd303dc04c3f744474e77c153575087b657f7e1 upstream.
The pingroups dump of debugfs hits WARN_ON() in pinctrl_groups_show().
Filling non-existing ports with '-1' turned out a bad idea.
Fixes: 336306ee1f2d ("pinctrl: uniphier: add UniPhier PH1-LD20 pinctrl driver")

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Gleixner <tglx@linutronix.de>
commit 3fa53ec2ed885b0aec3f0472e3b4a8a6f1cd748c upstream.
The irq chip callbacks irq_request/release_resources() have absolutely no
business with masking and unmasking the irq.
The core code unmasks the interrupt after complete setup and masks it
before invoking irq_release_resources().
The unmask is actually harmful as it happens before the interrupt is
completely initialized in __setup_irq().
Remove it.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maciej W. Rozycki <macro@linux-mips.org>
commit 68fe55680d0f3342969f49412fceabb90bdfadba upstream.
Fix a commit 3021773c7c3e ("MIPS: DEC: Avoid la pseudo-instruction in
delay slots") regression and remove assembly errors:
arch/mips/dec/int-handler.S: Assembler messages:
arch/mips/dec/int-handler.S:162: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:163: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:229: Error: Macro used $at after ".set noat"
arch/mips/dec/int-handler.S:230: Error: Macro used $at after ".set noat"
triggering with with the CPU_DADDI_WORKAROUNDS option set and the DADDIU
instruction. This is because with that option in place the instruction
becomes a macro, which expands to an LI/DADDU (or actually ADDIU/DADDU)
sequence that uses $at as a temporary register.
With CPU_DADDI_WORKAROUNDS we only support `-msym32' compilation though,
and this is already enforced in arch/mips/Makefile, so choose the 32-bit
expansion variant for the supported configurations and then replace the
64-bit variant with #error just in case.

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul Burton <paul.burton@imgtec.com>
commit ae5b0675942ab30cde96099c68a2290bd1aafcca upstream.
Commit 296e46db0073 ("MIPS: Don't unnecessarily include kmalloc.h into
<asm/cache.h>.") claimed that the inclusion of the machine's kmalloc.h
from asm/cache.h is unnecessary, but this is not true.
Without including kmalloc.h we don't get a definition for
ARCH_DMA_MINALIGN, which means we no longer suitably align DMA. Further
to this the definition of ARCH_KMALLOC_MINALIGN provided by linux/slab.h
ends up being set to the alignment of an unsigned long long value rather
than to ARCH_DMA_MINALIGN, which means that buffers allocated using
kmalloc may no longer be safely aligned for use with DMA.
Fix this by re-adding the include of kmalloc.h in asm/cache.h. This
reverts commit 296e46db0073 ("MIPS: Don't unnecessarily include
kmalloc.h into <asm/cache.h>.")

4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Neuling <mikey@neuling.org>
commit 64ebb9a208c6e66316329a6d9101815d1ee06fa9 upstream.
The P9 PVR bits 12-15 don't indicate a revision but instead different
chip configurations. From BookIV we have:
Bits Configuration
0 : Scale out 12 cores
1 : Scale out 24 cores
2 : Scale up 12 cores
3 : Scale up 24 cores
DD1 doesn't use this but DD2 does. Linux will mostly use the "Scale
out 24 core" configuration (ie. SMT4 not SMT8) which results in a PVR
of 0x004e1200. The reported revision in /proc/cpuinfo is hence
reported incorrectly as "18.0".
This patch fixes this to mask off only the relevant bits for the major
revision (ie. bits 8-11) for POWER9.
