[ Upstream commit 0c331fd1dccfba657129380ee084b95c1cedfbef ]
It is usually better to request all necessary resources (clocks,
regulators, ...) before starting to make use of them. That way they do
not change state in case one of the resources is not available yet and
probe deferral (-EPROBE_DEFER) is necessary. This is particularly
important for DMA channels and IOMMUs which are not enforced by
fw_devlink yet (unless you use fw_devlink.strict=1).
spi-qup does this in the wrong order, the clocks are enabled and
disabled again when the DMA channels are not available yet.
This causes issues in some cases: On most SoCs one of the SPI QUP
clocks is shared with the UART controller. When using earlycon UART is
actively used during boot but might not have probed yet, usually for
the same reason (waiting for the DMA controller). In this case, the
brief enable/disable cycle ends up gating the clock and further UART
console output will halt the system completely.
Avoid this by requesting the DMA channels before changing the clock
state.

commit ff1cc97b1f4c10db224f276d9615b22835b8c424 upstream.
Since gcc13, each member of an enum has the same type as the enum [1]. And
that is inherited from its members. Provided:
VTIME_PER_SEC_SHIFT = 37,
VTIME_PER_SEC = 1LLU << VTIME_PER_SEC_SHIFT,
...
AUTOP_CYCLE_NSEC = 10LLU * NSEC_PER_SEC,
the named type is unsigned long.
This generates warnings with gcc-13:
block/blk-iocost.c: In function 'ioc_weight_prfill':
block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int'
block/blk-iocost.c: In function 'ioc_weight_show':
block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int'
So split the anonymous enum with large values to a separate enum, so
that they don't affect other members.

commit 5f2779dfa7b8cc7dfd4a1b6586d86e0d193266f3 upstream.
The behavior of 'enum' types has changed in gcc-13, so now the
UNBUSY_THR_PCT constant is interpreted as a 64-bit number because
it is defined as part of the same enum definition as some other
constants that do not fit within a 32-bit integer. This in turn
leads to some inefficient code on 32-bit architectures as well
as a link error:
arm-linux-gnueabi/bin/arm-linux-gnueabi-ld: block/blk-iocost.o: in function `ioc_timer_fn':
blk-iocost.c:(.text+0x68e8): undefined reference to `__aeabi_uldivmod'
arm-linux-gnueabi-ld: blk-iocost.c:(.text+0x6908): undefined reference to `__aeabi_uldivmod'
Split the enum definition to keep the 64-bit timing constants in
a separate enum type from those constants that can clearly fit
within a smaller type.

commit f07788079f515ca4a681c5f595bdad19cfbd7b1d upstream.
gcc-13 slightly changes the type of constant expressions that are defined
in an enum, which triggers a compile time sanity check in libata:
linux/drivers/ata/libahci.c: In function 'ahci_led_store':
linux/include/linux/compiler_types.h:357:45: error: call to '__compiletime_assert_302' declared with attribute error: BUILD_BUG_ON failed: sizeof(_s) > sizeof(long)
357 | _compiletime_assert(condition, msg, __compiletime_assert_, __COUNTER__)
The new behavior is that sizeof() returns the same value for the
constant as it does for the enum type, which is generally more sensible
and consistent.
The problem in libata is that it contains a single enum definition for
lots of unrelated constants, some of which are large positive (unsigned)
integers like 0xffffffff, while others like (1<<31) are interpreted as
negative integers, and this forces the enum type to become 64 bit wide
even though most constants would still fit into a signed 32-bit 'int'.
Fix this by changing the entire enum definition to use BIT(x) in place
of (1<<x), which results in all values being seen as 'unsigned' and
fitting into an unsigned 32-bit type.

In commit a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting

to determine the lazy itable init thread should be enabled, with the
next result that the lazy inode table initialization would not be
properly started. This can cause generic/231 to fail in ext4's
nojournal mode.
Fix this by moving when we decide to start or stop the lazy itable
init thread to after we clear the SB_RDONLY flag when we are
remounting the file system read/write.

commit 8347b99473a313be6549a5b940bc3c56a71be81c upstream.
Copy the incoming @data comman to an internal buffer so that callers can
put SEV command buffers on the stack without running afoul of
CONFIG_VMAP_STACK=y, i.e. without bombing on vmalloc'd pointers. As of
today, the largest supported command takes a 68 byte buffer, i.e. pretty
much every command can be put on the stack. Because sev_cmd_mutex is
held for the entirety of a transaction, only a single bounce buffer is
required.
Use the internal buffer unconditionally, as the majority of in-kernel
users will soon switch to using the stack. At that point, checking
virt_addr_valid() becomes (negligible) overhead in most cases, and
supporting both paths slightly increases complexity. Since the commands
are all quite small, the cost of the copies is insignificant compared to
the latency of communicating with the PSP.
Allocate a full page for the buffer as opportunistic preparation for
SEV-SNP, which requires the command buffer to be in firmware state for
commands that trigger memory writes from the PSP firmware. Using a full
page now will allow SEV-SNP support to simply transition the page as
needed.

WARN on and reject SEV commands that provide a valid data pointer, but do
not have a known, non-zero length. And conversely, reject commands that
take a command buffer but none is provided (data is null).
Aside from sanity checking input, disallowing a non-null pointer without
a non-zero size will allow a future patch to cleanly handle vmalloc'd
data by copying the data to an internal __pa() friendly buffer.
Note, this also effectively prevents callers from using commands that
have a non-zero length and are not known to the kernel. This is not an
explicit goal, but arguably the side effect is a good thing from the
kernel's perspective.

adpt_isr() reads reply addresses from a hardware register, which
should always be within the DMA address range of the device's pool of
reply address buffers. In case the address is out of range, it tries
to muddle on, converting to a virtual address using bus_to_virt().
bus_to_virt() does not take DMA addresses, and it doesn't make sense
to try to handle the completion in this case. Ignore it and continue
looping to service the interrupt. If a completion has been lost then
the SCSI core should eventually time-out and trigger a reset.

adpt_i2o_passthru() takes a user-provided message and passes it
through to the hardware with appropriate translation of addresses
and message IDs. It has a number of bugs:
- When a message requires scatter/gather, it doesn't verify that the
offset to the scatter/gather list is less than the message size.
- When a message requires scatter/gather, it overwrites the DMA
addresses with the user-space virtual addresses before unmapping the
DMA buffers.
- It reads the message from user memory multiple times. This allows
user-space to change the message and bypass validation.
- It assumes that the message is at least 4 words long, but doesn't
check that.
I tried fixing these, but even the maintainer of the corresponding
user-space in Debian doesn't have the hardware any more.
Instead, remove the pass-through ioctl (I2OUSRCMD) and supporting
code.

Currently, when regmap_raw_write() splits the data, it uses the
max_raw_write value defined for the bus. For any bus that includes
the target register address in the max_raw_write value, the chunked
transmission will always exceed the maximum transmission length.
To avoid this problem, subtract the length of the register and the
padding from the maximum transmission.

commit c3d03e8e35e005e1a614e51bb59053eeb5857f76 upstream.
Commit ac4e97abce9b8 ("scatterlist: sg_set_buf() argument must be in linear
mapping") checks that both the signature and the digest reside in the
linear mapping area.
However, more recently commit ba14a194a434c ("fork: Add generic vmalloced
stack support") made it possible to move the stack in the vmalloc area,
which is not contiguous, and thus not suitable for sg_set_buf() which needs
adjacent pages.
Always make a copy of the signature and digest in the same buffer used to
store the key and its parameters, and pass them to sg_init_one(). Prefer it
to conditionally doing the copy if necessary, to keep the code simple. The
buffer allocated with kmalloc() is in the linear mapping area.

We can check if i overflows to solve the problem. However, this doesn't make
much sense, since i == 1 and num_pages == 1 doesn't execute the body of the loop.
In addition, i < num_pages can also ensure that buf->pages[i] will not cross
the boundary. Unfortunately, this doesn't help with the problem observed here:
gcc still complains.
To fix this add a compile-time condition for the extent buffer page
array size limit, which would eventually lead to eliminating the whole
for loop.

commit 2474e05467c00f7d51af3039b664de6886325257 upstream.
LPUART IP now has two known bugs, one is that CTS has higher priority
than the break signal, which causes the break signal sending through
UARTCTRL_SBK may impacted by the CTS input if the HW flow control is
enabled. It exists on all platforms we support in this driver.
So we add a workaround patch for this issue: commit c4c81db5cf8b
("tty: serial: fsl_lpuart: disable the CTS when send break signal").
Another IP bug is i.MX8QM LPUART may have an additional break character
being sent after SBK was cleared. It may need to add some delay between
clearing SBK and re-enabling CTS to ensure that the SBK latch are
completely cleared.
But we found that during the delay period before CTS is enabled, there
is still a risk that Bluetooth data in TX FIFO may be sent out during
this period because of break off and CTS disabled(even if BT sets CTS
line deasserted, data is still sent to BT).
Due to this risk, we have to drop the CTS-disabling workaround for SBK
bugs, use TXINV seems to be a better way to replace SBK feature and
avoid above risk. Also need to disable the transmitter to prevent any
data from being sent out during break, then invert the TX line to send
break. Then disable the TXINV when turn off break and re-enable
transmitter.

[ Upstream commit 49beadbd47c270a00754c107a837b4f29df4c822 ]
While the concept of checking for dangling pointers to local variables
at function exit is really interesting, the gcc-12 implementation is not
compatible with reality, and results in false positives.
For example, gcc sees us putting things on a local list head allocated
on the stack, which involves exactly those kinds of pointers to the
local stack entry:
In function ‘__list_add’,
inlined from ‘list_add_tail’ at include/linux/list.h:102:2,
inlined from ‘rebuild_snap_realms’ at fs/ceph/snap.c:434:2:
include/linux/list.h:74:19: warning: storing the address of local variable ‘realm_queue’ in ‘*&realm_27(D)->rebuild_item.prev’ [-Wdangling-pointer=]
74 | new->prev = prev;
| ~~~~~~~~~~^~~~~~
But then gcc - understandably - doesn't really understand the big
picture how the doubly linked list works, so doesn't see how we then end
up emptying said list head in a loop and the pointer we added has been
removed.
Gcc also complains about us (intentionally) using this as a way to store
a kind of fake stack trace, eg
drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]
40 | acpi_gbl_entry_stack_pointer = ¤t_sp;
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
which is entirely reasonable from a compiler standpoint, and we may want
to change those kinds of patterns, but not not.
So this is one of those "it would be lovely if the compiler were to
complain about us leaving dangling pointers to the stack", but not this
way.

commit 7f875850f20a42f488840c9df7af91ef7db2d576 upstream.
For devices not attached to a port multiplier and managed directly by
libata, the device number passed to ata_find_dev() must always be lower
than the maximum number of devices returned by ata_link_max_devices().
That is 1 for SATA devices or 2 for an IDE link with master+slave
devices. This device number is the SCSI device ID which matches these
constraints as the IDs are generated per port and so never exceed the
maximum number of devices for the link being used.
However, for libsas managed devices, SCSI device IDs are assigned per
struct scsi_host, leading to device IDs for SATA devices that can be
well in excess of libata per-link maximum number of devices. This
results in ata_find_dev() to always return NULL for libsas managed
devices except for the first device of the target scsi_host with ID
(device number) equal to 0. This issue is visible by executing the
hdparm utility, which fails. E.g.:
hdparm -i /dev/sdX
/dev/sdX:
HDIO_GET_IDENTITY failed: No message of desired type
Fix this by rewriting ata_find_dev() to ignore the device number for
non-PMP attached devices with a link with at most 1 device, that is SATA
devices. For these, the device number 0 is always used to
return the correct pointer to the struct ata_device of the port link.
This change excludes IDE master/slave setups (maximum number of devices
per link is 2) and port-multiplier attached devices. Also, to be
consistant with the fact that SCSI device IDs and channel numbers used
as device numbers are both unsigned int, change the devno argument of
ata_find_dev() to unsigned int.

commit 6d074ce231772c66e648a61f6bd2245e7129d1f5 upstream.
gcc 13 may assign another type to enumeration constants than gcc 12. Split
the large enum at the top of source file stex.c such that the type of the
constants used in time expressions is changed back to the same type chosen
by gcc 12. This patch suppresses compiler warnings like this one:
