commit bb523b406c849eef8f265a07cd7f320f1f177743 upstream
Turn fault_in_pages_{readable,writeable} into versions that return the
number of bytes not faulted in, similar to copy_to_user, instead of
returning a non-zero value when any of the requested pages couldn't be
faulted in. This supports the existing users that require all pages to
be faulted in as well as new users that are happy if any pages can be
faulted in.
Rename the functions to fault_in_{readable,writeable} to make sure
this change doesn't silently break things.
Neither of these functions is entirely trivial and it doesn't seem
useful to inline them, so move them to mm/gup.c.

commit 98d948eb833104a094517401ed8be26ba3ce9935 upstream.
Some versions of the Cadence QSPI controller does not have the write
completion register implemented(CQSPI_REG_WR_COMPLETION_CTRL). On the
Intel SoCFPGA platform the CQSPI_REG_WR_COMPLETION_CTRL register is
not configured.
Add a quirk to not write to the CQSPI_REG_WR_COMPLETION_CTRL register.

commit 233087ca063686964a53c829d547c7571e3f67bf upstream.
Minh Yuan reported a concurrency use-after-free issue in the floppy code
between raw_cmd_ioctl and seek_interrupt.
[ It turns out this has been around, and that others have reported the
KASAN splats over the years, but Minh Yuan had a reproducer for it and
so gets primary credit for reporting it for this fix - Linus ]
The problem is, this driver tends to break very easily and nowadays,
nobody is expected to use FDRAWCMD anyway since it was used to
manipulate non-standard formats. The risk of breaking the driver is
higher than the risk presented by this race, and accessing the device
requires privileges anyway.
Let's just add a config option to completely disable this ioctl and
leave it disabled by default. Distros shouldn't use it, and only those
running on antique hardware might need to enable it.

commit e5c23779f93d45e39a52758ca593bd7e62e9b4be upstream.
In the case where there is only a cycle counter available (i.e.
PMCR_EL0.N is 0) and an event other than CPU cycles is opened, the open
should fail as the event can never possibly be scheduled. However, the
event validation when an event is opened is skipped when the group
leader is opened. Fix this by always validating the group leader events.

commit 04ebaa1cfddae5f240cc7404f009133bb0389a47 upstream.
When we decode the latency and the max_latency, u16 value may not fit
the required size and could lead to the wrong LTR representation.
Scaling is represented as:
scale 0 - 1 (2^(5*0)) = 2^0
scale 1 - 32 (2^(5 *1))= 2^5
scale 2 - 1024 (2^(5 *2)) =2^10
scale 3 - 32768 (2^(5 *3)) =2^15
scale 4 - 1048576 (2^(5 *4)) = 2^20
scale 5 - 33554432 (2^(5 *4)) = 2^25
scale 4 and scale 5 required 20 and 25 bits respectively.
scale 6 reserved.
Replace the u16 type with the u32 type and allow corrected LTR
representation.

commit 06fb4ecfeac7e00d6704fa5ed19299f2fefb3cc9 upstream.
Commit 5467801f1fcb ("gpio: Restrict usage of GPIO chip irq members
before initialization") attempted to fix a race condition that lead to a
NULL pointer, but in the process caused a regression for _AEI/_EVT
declared GPIOs.
This manifests in messages showing deferred probing while trying to
allocate IRQs like so:
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
[ .. more of the same .. ]
The code for walking _AEI doesn't handle deferred probing and so this
leads to non-functional GPIO interrupts.
Fix this issue by moving the call to `acpi_gpiochip_request_interrupts`
to occur after gc->irc.initialized is set.

commit cbe6c3a8f8f4315b96e46e1a1c70393c06d95a4c upstream.
This will reset deeply on freeze and thaw instead of suspend and
resume and prevent null pointer dereferences of the uninitialized ring
0 buffer while thawing.
The impact is an indefinitely hanging kernel. You can't switch
consoles after this and the only possible user interaction is SysRq.
BUG: kernel NULL pointer dereference
RIP: 0010:aq_ring_rx_fill+0xcf/0x210 [atlantic]
aq_vec_init+0x85/0xe0 [atlantic]
aq_nic_init+0xf7/0x1d0 [atlantic]
atl_resume_common+0x4f/0x100 [atlantic]
pci_pm_thaw+0x42/0xa0
resolves in aq_ring.o to
```
0000000000000ae0 <aq_ring_rx_fill>:
{
/* ... */
baf: 48 8b 43 08 mov 0x8(%rbx),%rax
buff->flags = 0U; /* buff is NULL */
```
The bug has been present since the introduction of the new pm code in
8aaa112a57c1 ("net: atlantic: refactoring pm logic") and was hidden
until 8ce84271697a ("net: atlantic: changes for multi-TC support"),
which refactored the aq_vec_{free,alloc} functions into
aq_vec_{,ring}_{free,alloc}, but is technically not wrong. The
original functions just always reinitialized the buffers on S3/S4. If
the interface is down before freezing, the bug does not occur. It does
not matter, whether the initrd contains and loads the module before
thawing.
So the fix is to invert the boolean parameter deep in all pm function
calls, which was clearly intended to be set like that.
First report was on Github [1], which you have to guess from the
resume logs in the posted dmesg snippet. Recently I posted one on
Bugzilla [2], since I did not have an AQC device so far.

commit a3ae97f4c87d9570e7e9a3e3324c443757f6e29a upstream.
Commit b98ce2f4e32b ("dmaengine: imx-sdma: add uart rom script") broke
uart rx on imx5 when using sdma firmware from older Freescale 2.6.35
kernel. In this case reading addr->uartXX_2_mcu_addr was going out of
bounds of the firmware memory and corrupting the uart script addresses.
Simply adding a bounds check before accessing addr->uartXX_2_mcu_addr
does not work as the uartXX_2_mcu_addr members are now beyond the size
of the older firmware and the uart addresses would never be populated
in that case. There are other ways to fix this but overall the logic
seems clearer to me to revert the uartXX_2_mcu_ram_addr structure
entries back to uartXX_2_mcu_addr, change the newer entries to
uartXX_2_mcu_rom_addr and update the logic accordingly.
I have tested this patch on:
1. An i.MX53 system with sdma firmware from Freescale 2.6.35 kernel.
Without this patch uart rx is broken in this scenario, with the
patch uart rx is restored.
2. An i.MX6D system with no external sdma firmware. uart is okay with
or without this patch.
3. An i.MX8MM system using current sdma-imx7d.bin firmware from
linux-firmware. uart is okay with or without this patch and I
confirmed the rom version of the uart script is being used which was
the intention and reason for commit b98ce2f4e32b ("dmaengine:
imx-sdma: add uart rom script") in the first place.

We set the qedi_ep state to EP_STATE_OFLDCONN_START when the ep is
created. Then in qedi_set_path we kick off the offload work. If userspace
times out the connection and calls ep_disconnect, qedi will only flush the
offload work if the qedi_ep state has transitioned away from
EP_STATE_OFLDCONN_START. If we can't connect we will not have transitioned
state and will leave the offload work running, and we will free the qedi_ep
from under it.
This patch just has us init the work when we create the ep, then always
flush it.

[ Upstream commit 44ac97109e42f87b1a34954704b81b6c8eca80c4 ]
If a offload driver doesn't use the xmit workqueue, then when we are doing
ep_disconnect libiscsi can still inject PDUs to the driver. This adds a
check for if the connection is bound before trying to inject PDUs.

We can't release the endpoint ID until all references to the endpoint have
been dropped or it could be allocated while in use. This has us use an idr
instead of looping over all conns to find a free ID and then free the ID
when all references have been dropped instead of when the device is only
deleted.

[ Upstream commit 5ad7f18cd82cee8e773d40cc7a1465a526f2615c ]
commit 4298388574da ("net: macb: restart tx after tx used bit read")
added support for restarting transmission. Restarting tx does not work
in case controller asserts TXUBR interrupt and TQBP is already at the end
of the tx queue. In that situation, restarting tx will immediately cause
assertion of another TXUBR interrupt. The driver will end up in an infinite
interrupt loop which it cannot break out of.
For cases where TQBP is at the end of the tx queue, instead
only clear TX_USED interrupt. As more data gets pushed to the queue,
transmission will resume.
This issue was observed on a Xilinx Zynq-7000 based board.
During stress test of the network interface,
driver would get stuck on interrupt loop within seconds or minutes
causing CPU to stall.

[ Upstream commit 047ae665577776b7feb11bd4f81f46627cff95e7 ]
kzalloc() is a memory allocation function which can return NULL when
some internal memory errors happen. So it is better to check it to
prevent potential wrong memory access.
Besides, since mdp5_plane_reset() is void type, so we should better
set `plane-state` to NULL after releasing it.

[ Upstream commit 907862e9aef75bf89e2b265efcc58870be06081e ]
An infinite loop may occur if we fail to acquire the HW semaphore,
which is needed for resource release.
This will typically happen if the hardware is surprise-removed.
At this stage there is nothing to do, except log an error and quit.

[ Upstream commit f1d388f216aeb41a5df518815ae559d14a6d438e ]
Since the conversion to spi-mem, the driver advertised support for
various operations that cqspi_set_protocol() was never expected to handle
correctly - in particuar all non-DTR operations with command or address
buswidth > 1. For DTR, all operations except for 8-8-8 would fail, as
cqspi_set_protocol() returns -EINVAL.
In non-DTR mode, this resulted in data corruption for SPI-NOR flashes that
support such operations. As a minimal fix that can be backported to stable
kernels, simply disallow the unsupported operations again to avoid this
issue.

[ Upstream commit 317c2045618cc1f8d38beb8c93a7bdb6ad8638c6 ]
After system resumes, the registers of nor controller are
initialized with default values. The nor controller will
not function properly.
To handle both issues above, we add mtk_nor_init() in
mtk_nor_resume after pm_runtime_force_resume().
