45f540622d init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
commit ea29b20a828511de3348334e529a3d046a180416 upstream.

I read the commit log of the following two:

- bc083a64b6 ("init/Kconfig: make COMPILE_TEST depend on !UML")
- 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390")

Both are talking about HAS_IOMEM dependency missing in many drivers.

So, 'depends on HAS_IOMEM' seems the direct, sensible solution to me.

This does not change the behavior of UML. UML still cannot enable
COMPILE_TEST because it does not provide HAS_IOMEM.

The current dependency for S390 is too strong. Under the condition of
CONFIG_PCI=y, S390 provides HAS_IOMEM, hence can enable COMPILE_TEST.

I also removed the meaningless 'default n'.

43dd03f088 init/Kconfig: make COMPILE_TEST depend on !S390
commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream.

While allmodconfig and allyesconfig build for s390 there are also
various bots running compile tests with randconfig, where PCI is
disabled. This reveals that a lot of drivers should actually depend on
HAS_IOMEM.
Adding this to each device driver would be a never ending story,
therefore just disable COMPILE_TEST for s390.

The reasoning is more or less the same as described in
commit bc083a64b6 ("init/Kconfig: make COMPILE_TEST depend on !UML").

f5eb7e12a7 nvme-mpath: replace direct_make_request with generic_make_request
The below patches caused a regression in a multipath setup:
Fixes: 9f98772ba307 ("nvme-rdma: fix controller reset hang during traffic")
Fixes: 2875b0aecabe ("nvme-tcp: fix controller reset hang during traffic")

These patches on their own are correct because they fixed a controller reset
regression.

When we reset/teardown a controller, we must freeze and quiesce the namespaces
request queues to make sure that we safely stop inflight I/O submissions.
Freeze is mandatory because if our hctx map changed between reconnects,
blk_mq_update_nr_hw_queues will immediately attempt to freeze the queue, and
if it still has pending submissions (that are still quiesced) it will hang.
This is what the above patches fixed.

However, by freezing the namespaces request queues, and only unfreezing them
when we successfully reconnect, inflight submissions that are running
concurrently can now block grabbing the nshead srcu until either we successfully
reconnect or ctrl_loss_tmo expired (or the user explicitly disconnected).

This caused a deadlock [1] when a different controller (different path on the
same subsystem) became live (i.e. optimized/non-optimized). This is because
nvme_mpath_set_live needs to synchronize the nshead srcu before requeueing I/O
in order to make sure that current_path is visible to future (re)submisions.
However the srcu lock is taken by a blocked submission on a frozen request
queue, and we have a deadlock.

In recent kernels (v5.9+) direct_make_request was replaced by submit_bio_noacct
which does not have this issue because it bio_list will be active when
nvme-mpath calls submit_bio_noacct on the bottom device (because it was
populated when submit_bio was triggered on it.

Hence, we need to fix all the kernels that were before submit_bio_noacct was
introduced.

6cce305480 bpf, x86: Validate computation of branch displacements for x86-32
commit 26f55a59dc65ff77cd1c4b37991e26497fc68049 upstream.

The branch displacement logic in the BPF JIT compilers for x86 assumes
that, for any generated branch instruction, the distance cannot
increase between optimization passes.

But this assumption can be violated due to how the distances are
computed. Specifically, whenever a backward branch is processed in
do_jit(), the distance is computed by subtracting the positions in the
machine code from different optimization passes. This is because part
of addrs[] is already updated for the current optimization pass, before
the branch instruction is visited.

And so the optimizer can expand blocks of machine code in some cases.

This can confuse the optimizer logic, where it assumes that a fixed
point has been reached for all machine code blocks once the total
program size stops changing. And then the JIT compiler can output
abnormal machine code containing incorrect branch displacements.

To mitigate this issue, we assert that a fixed point is reached while
populating the output image. This rejects any problematic programs.
The issue affects both x86-32 and x86-64. We mitigate separately to
ease backporting.

20c60bbc1c cifs: Silently ignore unknown oplock break handle
[ Upstream commit 219481a8f90ec3a5eed9638fb35609e4b1aeece7 ]

Make SMB2 not print out an error when an oplock break is received for an
unknown handle, similar to SMB1.  The debug message which is printed for
these unknown handles may also be misleading, so fix that too.

The SMB2 lease break path is not affected by this patch.

Without this, a program which writes to a file from one thread, and
opens, reads, and writes the same file from another thread triggers the
below errors several times a minute when run against a Samba server
configured with "smb2 leases = no".

754c82a6bf cifs: revalidate mapping when we open files for SMB1 POSIX
[ Upstream commit cee8f4f6fcabfdf229542926128e9874d19016d5 ]

RHBZ: 1933527

Under SMB1 + POSIX, if an inode is reused on a server after we have read and
cached a part of a file, when we then open the new file with the
re-cycled inode there is a chance that we may serve the old data out of cache
to the application.
This only happens for SMB1 (deprecated) and when posix are used.
The simplest solution to avoid this race is to force a revalidate
on smb1-posix open.

0465098898 platform/x86: thinkpad_acpi: Allow the FnLock LED to change state
[ Upstream commit 3d677f12ea3a2097a16ded570623567403dea959 ]

On many recent ThinkPad laptops, there's a new LED next to the ESC key,
that indicates the FnLock status.
When the Fn+ESC combo is pressed, FnLock is toggled, which causes the
Media Key functionality to change, making it so that the media keys
either perform their media key function, or function as an F-key by
default. The Fn key can be used the access the alternate function at any
time.

With the current linux kernel, the LED doens't change state if you press
the Fn+ESC key combo. However, the media key functionality *does*
change. This is annoying, since the LED will stay on if it was on during
bootup, and it makes it hard to keep track what the current state of the
FnLock is.

This patch calls an ACPI function, that gets the current media key
state, when the Fn+ESC key combo is pressed. Through testing it was
discovered that this function causes the LED to update correctly to
reflect the current state when this function is called.

The relevant ACPI calls are the following:
\_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled.
\_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

[ Upstream commit 041c881a0ba8a75f71118bd9766b78f04beed469 ]

Even if the first channel from sband channel list is invalid
or disabled mac80211 ends up choosing it as the default channel
for monitor interfaces, making them not usable.

Fix this by assigning the first available valid or enabled
channel instead.

37b51460b2 mISDN: fix crash in fritzpci
[ Upstream commit a9f81244d2e33e6dfcef120fefd30c96b3f7cdb0 ]

setup_fritz() in avmfritz.c might fail with -EIO and in this case the
isac.type and isac.write_reg is not initialized and remains 0(NULL).
A subsequent call to isac_release() will dereference isac->write_reg and
crash.

901d39f7b2 net: pxa168_eth: Fix a potential data race in pxa168_eth_remove
[ Upstream commit 0571a753cb07982cc82f4a5115e0b321da89e1f3 ]

pxa168_eth_remove() firstly calls unregister_netdev(),
then cancels a timeout work. unregister_netdev() shuts down a device
interface and removes it from the kernel tables. If the timeout occurs
in parallel, the timeout work (pxa168_eth_tx_timeout_task) performs stop
and open of the device. It may lead to an inconsistent state and memory
leaks.

bec7103b04 ARM: dts: am33xx: add aliases for mmc interfaces
[ Upstream commit 9bbce32a20d6a72c767a7f85fd6127babd1410ac ]

Without DT aliases, the numbering of mmc interfaces is unpredictable.
Adding them makes it possible to refer to devices consistently.  The
popular suggestion to use UUIDs obviously doesn't work with a blank
device fresh from the factory.

See commit fa2d0aa96941 ("mmc: core: Allow setting slot index via
device tree alias") for more discussion.

0ca13611d3 staging: rtl8192e: Change state information from u16 to u8
commit e78836ae76d20f38eed8c8c67f21db97529949da upstream.

The "u16 CcxRmState[2];" array field in struct "rtllib_network" has 4
bytes in total while the operations performed on this array through-out
the code base are only 2 bytes.

The "CcxRmState" field is fed only 2 bytes of data using memcpy():

(In rtllib_rx.c:1972)
	memcpy(network->CcxRmState, &info_element->data[4], 2)

With "info_element->data[]" being a u8 array, if 2 bytes are written
into "CcxRmState" (whose one element is u16 size), then the 2 u8
elements from "data[]" gets squashed and written into the first element
("CcxRmState[0]") while the second element ("CcxRmState[1]") is never
fed with any data.

Same in file rtllib_rx.c:2522:
	 memcpy(dst->CcxRmState, src->CcxRmState, 2);

The above line duplicates "src" data to "dst" but only writes 2 bytes
(and not 4, which is the actual size). Again, only 1st element gets the
value while the 2nd element remains uninitialized.

This later makes operations done with CcxRmState unpredictable in the
following lines as the 1st element is having a squashed number while the
2nd element is having an uninitialized random number.

rtllib_rx.c:1973:    if (network->CcxRmState[0] != 0)
rtllib_rx.c:1977:    network->MBssidMask = network->CcxRmState[1] & 0x07;

network->MBssidMask is also of type u8 and not u16.

Fix this by changing the type of "CcxRmState" from u16 to u8 so that the
data written into this array and read from it make sense and are not
random values.

NOTE: The wrong initialization of "CcxRmState" can be seen in the
following commit:

commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")

The above commit created a file `rtl8192e/ieee80211.h` which used to
have the faulty line. The file has been deleted (or possibly renamed)
with the contents copied in to a new file `rtl8192e/rtllib.h` along with
additional code in the commit 94a799425e (tagged in Fixes).

f9974f189c staging: rtl8192e: Fix incorrect source in memcpy()
commit 72ad25fbbb78930f892b191637359ab5b94b3190 upstream.

The variable "info_element" is of the following type:

	struct rtllib_info_element *info_element

defined in drivers/staging/rtl8192e/rtllib.h:

	struct rtllib_info_element {
		u8 id;
		u8 len;
		u8 data[];
	} __packed;

The "len" field defines the size of the "data[]" array. The code is
supposed to check if "info_element->len" is greater than 4 and later
equal to 6. If this is satisfied then, the last two bytes (the 4th and
5th element of u8 "data[]" array) are copied into "network->CcxRmState".

Right now the code uses "memcpy()" with the source as "&info_element[4]"
which would copy in wrong and unintended information. The struct
"rtllib_info_element" has a size of 2 bytes for "id" and "len",
therefore indexing will be done in interval of 2 bytes. So,
"info_element[4]" would point to data which is beyond the memory
allocated for this pointer (that is, at x+8, while "info_element" has
been allocated only from x to x+7 (2 + 6 => 8 bytes)).

This patch rectifies this error by using "&info_element->data[4]" which
correctly copies the last two bytes of "data[]".

NOTE: The faulty line of code came from the following commit:

commit ecdfa44610 ("Staging: add Realtek 8192 PCI wireless driver")

The above commit created the file `rtl8192e/ieee80211/ieee80211_rx.c`
which had the faulty line of code. This file has been deleted (or
possibly renamed) with the contents copied in to a new file
`rtl8192e/rtllib_rx.c` along with additional code in the commit
94a799425e (tagged in Fixes).

fd5ce87aee usb: dwc2: Prevent core suspend when port connection flag is 0
commit 93f672804bf2d7a49ef3fd96827ea6290ca1841e upstream.

In host mode port connection status flag is "0" when loading
the driver. After loading the driver system asserts suspend
which is handled by "_dwc2_hcd_suspend()" function. Before
the system suspend the port connection status is "0". As
result need to check the "port_connect_status" if it is "0",
then skipping entering to suspend.

commit 72035f4954f0bca2d8c47cf31b3629c42116f5b7 upstream.

init_dma_pools() calls dma_pool_create(...dev->dev) to create dma pool.
however, dev->dev is actually set after calling init_dma_pools(), which
effectively makes dma_pool_create(..NULL) and cause crash.
To fix this issue, init dma only after dev->dev is set.

commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd upstream.

This LTE modem (M.2 card) has a bug in its power management:
there is some kind of race condition for U3 wake-up between the host and
the device. The modem firmware sometimes crashes/locks when both events
happen at the same time and the modem fully drops off the USB bus (and
sometimes re-enumerates, sometimes just gets stuck until the next
reboot).

Tested with the modem wired to the XHCI controller on an AMD 3015Ce
platform. Without the patch, the modem dropped of the USB bus 5 times in
3 days. With the quirk, it stayed connected for a week while the
'runtime_suspended_time' counter incremented as excepted.

5ecfad1efb firewire: nosy: Fix a use-after-free bug in nosy_ioctl()
[ Upstream commit 829933ef05a951c8ff140e814656d73e74915faf ]

For each device, the nosy driver allocates a pcilynx structure.
A use-after-free might happen in the following scenario:

 1. Open nosy device for the first time and call ioctl with command
    NOSY_IOC_START, then a new client A will be malloced and added to
    doubly linked list.
 2. Open nosy device for the second time and call ioctl with command
    NOSY_IOC_START, then a new client B will be malloced and added to
    doubly linked list.
 3. Call ioctl with command NOSY_IOC_START for client A, then client A
    will be readded to the doubly linked list. Now the doubly linked
    list is messed up.
 4. Close the first nosy device and nosy_release will be called. In
    nosy_release, client A will be unlinked and freed.
 5. Close the second nosy device, and client A will be referenced,
    resulting in UAF.

The root cause of this bug is that the element in the doubly linked list
is reentered into the list.

Fix this bug by adding a check before inserting a client.  If a client
is already in the linked list, don't insert it.

The following KASAN report reveals it:

58073dc536 extcon: Fix error handling in extcon_dev_register
[ Upstream commit d3bdd1c3140724967ca4136755538fa7c05c2b4e ]

When devm_kcalloc() fails, we should execute device_unregister()
to unregister edev->dev from system.

e3a3d5005e extcon: Add stubs for extcon_register_notifier_all() functions
[ Upstream commit c9570d4a5efd04479b3cd09c39b571eb031d94f4 ]

Add stubs for extcon_register_notifier_all() function for !CONFIG_EXTCON
case.  This is useful for compile testing and for drivers which use
EXTCON but do not require it (therefore do not depend on CONFIG_EXTCON).

c92e8a8ecb vfio/nvlink: Add missing SPAPR_TCE_IOMMU depends
commit e0146a108ce4d2c22b9510fd12268e3ee72a0161 upstream.

Compiling the nvlink stuff relies on the SPAPR_TCE_IOMMU otherwise there
are compile errors:

 drivers/vfio/pci/vfio_pci_nvlink2.c:101:10: error: implicit declaration of function 'mm_iommu_put' [-Werror,-Wimplicit-function-declaration]
                            ret = mm_iommu_put(data->mm, data->mem);

As PPC only defines these functions when the config is set.

Previously this wasn't a problem by chance as SPAPR_TCE_IOMMU was the only
IOMMU that could have satisfied IOMMU_API on POWERNV.
