PCI: aardvark: Simplify initialization of rootcap on virtual bridge
commit 454c53271fc11f3aa5e44e41fd99ca181bd32c62 upstream. PCIe config space can be initialized also before pci_bridge_emul_init() call, so move rootcap initialization after PCI config space initialization. This simplifies the function a little since it removes one if (ret < 0) check.

PCI: aardvark: Implement re-issuing config requests on CRS response
commit 223dec14a05337a4155f1deed46d2becce4d00fd upstream.
Commit 43f5c77bcbd2 ("PCI: aardvark: Fix reporting CRS value") fixed
handling of CRS response and when CRSSVE flag was not enabled it marked CRS
response as failed transaction (due to simplicity).
But pci-aardvark.c driver is already waiting up to the PIO_RETRY_CNT count
for PIO config response and so we can with a small change implement
re-issuing of config requests as described in PCIe base specification.
This change implements re-issuing of config requests when response is CRS.
Set upper bound of wait cycles to around PIO_RETRY_CNT, afterwards the
transaction is marked as failed and an all-ones value is returned as
before.
We do this by returning appropriate error codes from function
advk_pcie_check_pio_status(). On CRS we return -EAGAIN and caller then
reissues transaction.

mdio: aspeed: Fix "Link is Down" issue
commit 9dbe33cf371bd70330858370bdbc35c7668f00c3 upstream.
The issue happened randomly in runtime. The message "Link is Down" is
popped but soon it recovered to "Link is Up".
The "Link is Down" results from the incorrect read data for reading the
PHY register via MDIO bus. The correct sequence for reading the data
shall be:
1. fire the command
2. wait for command done (this step was missing)
3. wait for data idle
4. read data from data register

mmc: sdhci: Fix ADMA for PAGE_SIZE >= 64KiB
commit 3d7c194b7c9ad414264935ad4f943a6ce285ebb1 upstream. The block layer forces a minimum segment size of PAGE_SIZE, so a segment can be too big for the ADMA table, if PAGE_SIZE >= 64KiB.

KVM: PPC: Book3S HV: Prevent POWER7/8 TLB flush flushing SLB
commit cf0b0e3712f7af90006f8317ff27278094c2c128 upstream. The POWER9 ERAT flush instruction is a SLBIA with IH=7, which is a reserved value on POWER7/8. On POWER8 this invalidates the SLB entries above index 0, similarly to SLBIA IH=0. If the SLB entries are invalidated, and then the guest is bypassed, the host SLB does not get re-loaded, so the bolted entries above 0 will be lost. This can result in kernel stack access causing a SLB fault. Kernel stack access causing a SLB fault was responsible for the infamous mega bug (search "Fix SLB reload bug"). Although since commit |

xen: detect uninitialized xenbus in xenbus_init
commit 36e8f60f0867d3b70d398d653c17108459a04efe upstream. If the xenstore page hasn't been allocated properly, reading the value of the related hvm_param (HVM_PARAM_STORE_PFN) won't actually return error. Instead, it will succeed and return zero. Instead of attempting to xen_remap a bad guest physical address, detect this condition and return early. Note that although a guest physical address of zero for HVM_PARAM_STORE_PFN is theoretically possible, it is not a good choice and zero has never been validly used in that capacity. Also recognize all bits set as an invalid value. For 32-bit Linux, any pfn above ULONG_MAX would get truncated. Pfns above ULONG_MAX should never be passed by the Xen tools to HVM guests anyway, so check for this condition and return early.

fuse: release pipe buf after last use
commit 473441720c8616dfaf4451f9c7ea14f0eb5e5d65 upstream.
Checking buf->flags should be done before the pipe_buf_release() is called
on the pipe buffer, since releasing the buffer might modify the flags.
This is exactly what page_cache_pipe_buf_release() does, and which results
in the same VM_BUG_ON_PAGE(PageLRU(page)) that the original patch was
trying to fix.

HID: wacom: Use "Confidence" flag to prevent reporting invalid contacts
commit 7fb0413baa7f8a04caef0c504df9af7e0623d296 upstream.
The HID descriptor of many of Wacom's touch input devices include a
"Confidence" usage that signals if a particular touch collection contains
useful data. The driver does not look at this flag, however, which causes
even invalid contacts to be reported to userspace. A lucky combination of
kernel event filtering and device behavior (specifically: contact ID 0 ==
invalid, contact ID >0 == valid; and order all data so that all valid
contacts are reported before any invalid contacts) spare most devices from
any visibly-bad behavior.
The DTH-2452 is one example of an unlucky device that misbehaves. It uses
ID 0 for both the first valid contact and all invalid contacts. Because
we report both the valid and invalid contacts, the kernel reports that
contact 0 first goes down (valid) and then goes up (invalid) in every
report. This causes ~100 clicks per second simply by touching the screen.
This patch inroduces new `confidence` flag in our `hid_data` structure.
The value is initially set to `true` at the start of a report and can be
set to `false` if an invalid touch usage is seen.

This reverts commit 279917e27edc293eb645a25428c6ab3f3bca3f86.

kernel bugs at runtime:

The problem is, that we have an init section of at least 2MB size which
starts at _stext and is freed after bootup.
If then later some kernel data is (temporarily) stored in this free
memory, check_kernel_text_object() will trigger a bug since the data
appears to be inside the kernel text (>=_stext) area:

ALSA: ctxfi: Fix out-of-range access
commit 76c47183224c86e4011048b80f0e2d0d166f01c2 upstream. The master and next_conj of rcs_ops are used for iterating the resource list entries, and currently those are supposed to return the current value. The problem is that next_conf may go over the last entry before the loop abort condition is evaluated, and it may return the "current" value that is beyond the array size. It was caught recently as a GPF, for example. Those return values are, however, never actually evaluated, hence basically we don't have to consider the current value as the return at all. By dropping those return values, the potential out-of-range access above is also fixed automatically. This patch changes the return type of master and next_conj callbacks to void and drop the superfluous code accordingly.

usb: hub: Fix usb enumeration issue due to address0 race
commit 6ae6dc22d2d1ce6aa77a6da8a761e61aca216f8b upstream.
xHC hardware can only have one slot in default state with address 0
waiting for a unique address at a time, otherwise "undefined behavior
may occur" according to xhci spec 5.4.3.4
The address0_mutex exists to prevent this across both xhci roothubs.
If hub_port_init() fails, it may unlock the mutex and exit with a xhci
slot in default state. If the other xhci roothub calls hub_port_init()
at this point we end up with two slots in default state.
Make sure the address0_mutex protects the slot default state across
hub_port_init() retries, until slot is addressed or disabled.
Note, one known minor case is not fixed by this patch.
If device needs to be reset during resume, but fails all hub_port_init()
retries in usb_reset_and_verify_device(), then it's possible the slot is
still left in default state when address0_mutex is unlocked.

usb: typec: fusb302: Fix masking of comparator and bc_lvl interrupts
commit 362468830dd5bea8bf6ad5203b2ea61f8a4e8288 upstream.
The code that enables either BC_LVL or COMP_CHNG interrupt in tcpm_set_cc
wrongly assumes that the interrupt is unmasked by writing 1 to the apropriate
bit in the mask register. In fact, interrupts are enabled when the mask
is 0, so the tcpm_set_cc enables interrupt for COMP_CHNG when it expects
BC_LVL interrupt to be enabled.
This causes inability of the driver to recognize cable unplug events
in host mode (unplug is recognized only via a COMP_CHNG interrupt).
In device mode this bug was masked by simultaneous triggering of the VBUS
change interrupt, because of loss of VBUS when the port peer is providing
power.

usb: chipidea: ci_hdrc_imx: fix potential error pointer dereference in probe
commit d4d2e5329ae9dfd6742c84d79f7d143d10410f1b upstream.
If the first call to devm_usb_get_phy_by_phandle(dev, "fsl,usbphy", 0)
fails with something other than -ENODEV then it leads to an error
pointer dereference. For those errors we should just jump directly to
the error handling.

net: nexthop: fix null pointer dereference when IPv6 is not enabled
commit 1c743127cc54b112b155f434756bd4b5fa565a99 upstream. When we try to add an IPv6 nexthop and IPv6 is not enabled (!CONFIG_IPV6) we'll hit a NULL pointer dereference[1] in the error path of nh_create_ipv6() due to calling ipv6_stub->fib6_nh_release. The bug has been present since the beginning of IPv6 nexthop gateway support. Commit |

usb: dwc3: gadget: Fix null pointer exception
commit 26288448120b28af1dfd85a6fa6b6d55a16c7f2f upstream.
In the endpoint interrupt functions
dwc3_gadget_endpoint_transfer_in_progress() and
dwc3_gadget_endpoint_trbs_complete() will dereference the endpoint
descriptor. But it could be cleared in __dwc3_gadget_ep_disable()
when accessory disconnected. So we need to check whether it is null
or not before dereferencing it.

usb: dwc3: gadget: Check for L1/L2/U3 for Start Transfer
commit 63c4c320ccf77074ffe9019ac596603133c1b517 upstream.
The programming guide noted that the driver needs to verify if the link
state is in U0 before executing the Start Transfer command. If it's not
in U0, the driver needs to perform remote wakeup. This is not accurate.
If the link state is in U1/U2, then the controller will not respond to
link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command
will trigger a link recovery if it is in U1/U2. A clarification will be
added to the programming guide for all controller versions.
The current implementation shouldn't cause any functional issue. It may
occasionally report an invalid time out warning from failed link
recovery request. The driver will still go ahead with the Start Transfer
command if the remote wakeup fails. The new change only initiates remote
wakeup where it is needed, which is when the link state is in L1/L2/U3.

usb: dwc3: gadget: Ignore NoStream after End Transfer
commit d74dc3e9f58c28689cef1faccf918e06587367d3 upstream.
The End Transfer command from a stream endpoint will generate a NoStream
event, and we should ignore it. Currently we set the flag
DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command,
and it will be cleared on the next stream event. However, a stream event
may be generated before the End Transfer command completion and
prematurely clear the flag. Fix this by setting the flag on End Transfer
completion instead.

usb: dwc2: hcd_queue: Fix use of floating point literal
commit 310780e825f3ffd211b479b8f828885a6faedd63 upstream.
A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).
drivers/usb/dwc2/hcd_queue.c:1744:25: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
delay = ktime_set(0, DWC2_RETRY_WAIT_DELAY);
^
drivers/usb/dwc2/hcd_queue.c:62:34: note: expanded from macro 'DWC2_RETRY_WAIT_DELAY'
#define DWC2_RETRY_WAIT_DELAY (1 * 1E6L)
^
1 error generated.
This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.
There is no visible reason for a floating point value in this driver, as
the value is only used as a parameter to a function that expects an
integer type. Use NSEC_PER_MSEC, which is the same integer value as
'1E6L', to avoid changing functionality but fix the error.

usb: dwc2: gadget: Fix ISOC flow for elapsed frames
commit 7ad4a0b1d46b2612f4429a72afd8f137d7efa9a9 upstream.
Added updating of request frame number for elapsed frames,
otherwise frame number will remain as previous use of request.
This will allow function driver to correctly track frames in
case of Missed ISOC occurs.
Added setting request actual length to 0 for elapsed frames.
In Slave mode when pushing data to RxFIFO by dwords, request
actual length incrementing accordingly. But before whole packet
will be pushed into RxFIFO and send to host can occurs Missed
ISOC and data will not send to host. So, in this case request
actual length should be reset to 0.

ACPI: Get acpi_device's parent from the parent field
commit 9054fc6d57e80c27c0b0632966416144f2092c2b upstream.
Printk modifier %pfw is used to print the full path of the device name.
This is obtained device by device until a device no longer has a parent.
On ACPI getting the parent fwnode is done by calling acpi_get_parent()
which tries to down() a semaphore. But local IRQs are now disabled in
vprintk_store() before the mutex is acquired. This is obviously a problem.
Luckily struct device, embedded in struct acpi_device, has a parent field
already. Use that field to get the parent instead of relying on
acpi_get_parent().

ALSA: hda: hdac_stream: fix potential locking issue in snd_hdac_stream_assign()
commit 1465d06a6d8580e73ae65f8590392df58c5ed2fd upstream. The fields 'opened', 'running', 'assigned_key' are all protected by a spinlock, but the spinlock is not taken when looking for a stream. This can result in a possible race between assign() and release(). Fix by taking the spinlock before walking through the bus stream list.

ALSA: hda: hdac_ext_stream: fix potential locking issues
commit 868ddfcef31ff93ea8961b2e81ea7fe12f6f144b upstream. The code for hdac_ext_stream seems inherited from hdac_stream, and similar locking issues are present: the use of the bus->reg_lock spinlock is inconsistent, with only writes to specific fields being protected. Apply similar fix as in hdac_stream by protecting all accesses to 'link_locked' and 'decoupled' fields, with a new helper snd_hdac_ext_stream_decouple_locked() added to simplify code changes.

x86/Kconfig: Fix an unused variable error in dell-smm-hwmon
commit ef775a0e36c6a81c5b07cb228c02f967133fe768 upstream.
When CONFIG_PROC_FS is not set, there is a build warning (turned
into an error):
../drivers/hwmon/dell-smm-hwmon.c: In function 'i8k_init_procfs':
../drivers/hwmon/dell-smm-hwmon.c:624:24: error: unused variable 'data' [-Werror=unused-variable]
struct dell_smm_data *data = dev_get_drvdata(dev);
Make I8K depend on PROC_FS and HWMON (instead of selecting HWMON -- it
is strongly preferred to not select entire subsystems).
Build tested in all possible combinations of SENSORS_DELL_SMM, I8K, and
PROC_FS.

btrfs: update device path inode time instead of bd_inode
commit 54fde91f52f515e0b1514f0f0fa146e87a672227 upstream.
Christoph pointed out that I'm updating bdev->bd_inode for the device
time when we remove block devices from a btrfs file system, however this
isn't actually exposed to anything. The inode we want to update is the
one that's associated with the path to the device, usually on devtmpfs,
so that blkid notices the difference.
We still don't want to do the blkdev_open, so use kern_path() to get the
path to the given device and do the update time on that inode.

fs: export an inode_update_time helper
commit e60feb445fce9e51c1558a6aa7faf9dd5ded533b upstream. If you already have an inode and need to update the time on the inode there is no way to do this properly. Export this helper to allow file systems to update time on the inode so the appropriate handler is called, either ->update_time or generic_update_time.

usb: max-3421: Use driver data instead of maintaining a list of bound devices
commit fc153aba3ef371d0d76eb88230ed4e0dee5b38f2 upstream.
Instead of maintaining a single-linked list of devices that must be
searched linearly in .remove() just use spi_set_drvdata() to remember the
link between the spi device and the driver struct. Then the global list
and the next member can be dropped.
This simplifies the driver, reduces the memory footprint and the time to
search the list. Also it makes obvious that there is always a corresponding
driver struct for a given device in .remove(), so the error path for
!max3421_hcd can be dropped, too.
As a side effect this fixes a data inconsistency when .probe() races with
itself for a second max3421 device in manipulating max3421_hcd_list. A
similar race is fixed in .remove(), too.

ASoC: DAPM: Cover regression by kctl change notification fix
commit 827b0913a9d9d07a0c3e559dbb20ca4d6d285a54 upstream.
The recent fix for DAPM to correct the kctl change notification by the
commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change
notifications") caused other regressions since it changed the behavior
of snd_soc_dapm_set_pin() that is called from several API functions.
Formerly it returned always 0 for success, but now it returns 0 or 1.
This patch addresses it, restoring the old behavior of
snd_soc_dapm_set_pin() while keeping the fix in
snd_soc_dapm_put_pin_switch().

selinux: fix NULL-pointer dereference when hashtab allocation fails
commit dc27f3c5d10c58069672215787a96b4fae01818b upstream.
When the hash table slot array allocation fails in hashtab_init(),
h->size is left initialized with a non-zero value, but the h->htable
pointer is NULL. This may then cause a NULL pointer dereference, since
the policydb code relies on the assumption that even after a failed
hashtab_init(), hashtab_map() and hashtab_destroy() can be safely called
on it. Yet, these detect an empty hashtab only by looking at the size.
Fix this by making sure that hashtab_init() always leaves behind a valid
empty hashtab when the allocation fails.
