a395121fe2 iio: adc: rtq6056: Correct the sign bit index
[ Upstream commit 9b45744bf09fc2a3287e05287141d6e123c125a7 ]

The vshunt/current reported register is a signed 16bit integer. The
sign bit index should be '15', not '16'.

094f10f3f2 can: rcar_canfd: Fix CAN-FD mode as default
[ Upstream commit 6d849ff573722afcf5508d2800017bdd40f27eb9 ]

The commit 5cff263606a1 ("can: rcar_canfd: Fix controller mode setting")
has aligned with the flow mentioned in the hardware manual for all SoCs
except R-Car Gen3 and RZ/G2L SoCs. On R-Car Gen4 and RZ/G3E SoCs, due to
the wrong logic in the commit[1] sets the default mode to FD-Only mode
instead of CAN-FD mode.

This patch sets the CAN-FD mode as the default for all SoCs by dropping
the rcar_canfd_set_mode() as some SoC requires mode setting in global
reset mode, and the rest of the SoCs in channel reset mode and update the
rcar_canfd_reset_controller() to take care of these constraints. Moreover,
the RZ/G3E and R-Car Gen4 SoCs support 3 modes compared to 2 modes on the
R-Car Gen3. Use inverted logic in rcar_canfd_reset_controller() to
simplify the code later to support FD-only mode.

eecd163fa6 usb: typec: ucsi: psy: Set max current to zero when disconnected
[ Upstream commit 23379a17334fc24c4a9cbd9967d33dcd9323cc7c ]

The ucsi_psy_get_current_max function defaults to 0.1A when it is not
clear how much current the partner device can support. But this does
not check the port is connected, and will report 0.1A max current when
nothing is connected. Update ucsi_psy_get_current_max to report 0A when
there is no connection.

f02a412c0a usb: gadget: udc: fix use-after-free in usb_gadget_state_work
[ Upstream commit baeb66fbd4201d1c4325074e78b1f557dff89b5b ]

A race condition during gadget teardown can lead to a use-after-free
in usb_gadget_state_work(), as reported by KASAN:

  BUG: KASAN: invalid-access in sysfs_notify+0x2c/0xd0
  Workqueue: events usb_gadget_state_work

The fundamental race occurs because a concurrent event (e.g., an
interrupt) can call usb_gadget_set_state() and schedule gadget->work
at any time during the cleanup process in usb_del_gadget().

Commit 399a45e5237c ("usb: gadget: core: flush gadget workqueue after
device removal") attempted to fix this by moving flush_work() to after
device_del(). However, this does not fully solve the race, as a new
work item can still be scheduled *after* flush_work() completes but
before the gadget's memory is freed, leading to the same use-after-free.

This patch fixes the race condition robustly by introducing a 'teardown'
flag and a 'state_lock' spinlock to the usb_gadget struct. The flag is
set during cleanup in usb_del_gadget() *before* calling flush_work() to
prevent any new work from being scheduled once cleanup has commenced.
The scheduling site, usb_gadget_set_state(), now checks this flag under
the lock before queueing the work, thus safely closing the race window.

0722d804f7 nfsd: Replace clamp_t in nfsd4_get_drc_mem()
A recent change to clamp_t() in 6.1.y caused fs/nfsd/nfs4state.c to fail
to compile with gcc-9. The code in nfsd4_get_drc_mem() was written with
the assumption that when "max < min",

   clamp(val, min, max)

would return max.  This assumption is not documented as an API promise
and the change caused a compile failure if it could be statically
determined that "max < min".

The relevant code was no longer present upstream when commit 1519fbc8832b
("minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp()")
landed there, so there is no upstream change to nfsd4_get_drc_mem() to
backport.

There is no clear case that the existing code in nfsd4_get_drc_mem()
is functioning incorrectly. The goal of this patch is to permit the clean
application of commit 1519fbc8832b ("minmax.h: use BUILD_BUG_ON_MSG() for
the lo < hi test in clamp()"), and any commits that depend on it, to LTS
kernels without affecting the ability to compile those kernels. This is
done by open-coding the __clamp() macro sans the built-in type checking.

5106da73b0 bonding: check xdp prog when set bond mode
[ Upstream commit 094ee6017ea09c11d6af187935a949df32803ce0 ]

Following operations can trigger a warning[1]:

    ip netns add ns1
    ip netns exec ns1 ip link add bond0 type bond mode balance-rr
    ip netns exec ns1 ip link set dev bond0 xdp obj af_xdp_kern.o sec xdp
    ip netns exec ns1 ip link set bond0 type bond mode broadcast
    ip netns del ns1

When delete the namespace, dev_xdp_uninstall() is called to remove xdp
program on bond dev, and bond_xdp_set() will check the bond mode. If bond
mode is changed after attaching xdp program, the warning may occur.

Some bond modes (broadcast, etc.) do not support native xdp. Set bond mode
with xdp program attached is not good. Add check for xdp program when set
bond mode.

694a354ddf bonding: return detailed error when loading native XDP fails
[ Upstream commit 22ccb684c1cae37411450e6e86a379cd3c29cb8f ]

Bonding only supports native XDP for specific modes, which can lead to
confusion for users regarding why XDP loads successfully at times and
fails at others. This patch enhances error handling by returning detailed
error messages, providing users with clearer insights into the specific
reasons for the failure when loading native XDP.

183ad6e3b6 libceph: fix potential use-after-free in have_mon_and_osd_map()
commit 076381c261374c587700b3accf410bdd2dba334e upstream.

The wait loop in __ceph_open_session() can race with the client
receiving a new monmap or osdmap shortly after the initial map is
received.  Both ceph_monc_handle_map() and handle_one_map() install
a new map immediately after freeing the old one

    kfree(monc->monmap);
    monc->monmap = monmap;

    ceph_osdmap_destroy(osdc->osdmap);
    osdc->osdmap = newmap;

under client->monc.mutex and client->osdc.lock respectively, but
because neither is taken in have_mon_and_osd_map() it's possible for
client->monc.monmap->epoch and client->osdc.osdmap->epoch arms in

    client->monc.monmap && client->monc.monmap->epoch &&
        client->osdc.osdmap && client->osdc.osdmap->epoch;

condition to dereference an already freed map.  This happens to be
reproducible with generic/395 and generic/397 with KASAN enabled:

Rewrite the wait loop to check the above condition directly with
client->monc.mutex and client->osdc.lock taken as appropriate.  While
at it, improve the timeout handling (previously mount_timeout could be
exceeded in case wait_event_interruptible_timeout() slept more than
once) and access client->auth_err under client->monc.mutex to match
how it's set in finish_auth().

monmap_show() and osdmap_show() now take the respective lock before
accessing the map as well.

748ed1b6a2 drm: sti: fix device leaks at component probe
commit 620a8f131154250f6a64a07d049a4f235d6451a5 upstream.

Make sure to drop the references taken to the vtg devices by
of_find_device_by_node() when looking up their driver data during
component probe.

Note that holding a reference to a platform device does not prevent its
driver data from going away so there is no point in keeping the
reference after the lookup helper returns.

commit 2d8ab771d5316de64f3bb920b82575c58eb00b1b upstream.

The U-Blox EVK-M101 enumerates as 1546:0506 [1] with four FTDI interfaces:
- EVK-M101 current sensors
- EVK-M101 I2C
- EVK-M101 UART
- EVK-M101 port D

Only the third USB interface is a UART. This change lets ftdi_sio probe
the VID/PID and registers only interface #3 as a TTY, leaving the rest
available for other drivers.

b75d203017 xhci: dbgtty: fix device unregister
commit 1f73b8b56cf35de29a433aee7bfff26cea98be3f upstream.

When DbC is disconnected then xhci_dbc_tty_unregister_device()
is called. However if there is any user space process blocked
on write to DbC terminal device then it will never be signalled
and thus stay blocked indifinitely.

This fix adds a tty_vhangup() call in xhci_dbc_tty_unregister_device().
The tty_vhangup() wakes up any blocked writers and causes subsequent
write attempts to DbC terminal device to fail.

da7a52bcee xhci: dbgtty: Fix data corruption when transmitting data form DbC to host
commit f6bb3b67be9af0cfb90075c60850b6af5338a508 upstream.

Data read from a DbC device may be corrupted due to a race between
ongoing write and write request completion handler both queuing new
transfer blocks (TRBs) if there are remining data in the kfifo.

TRBs may be in incorrct order compared to the data in the kfifo.

Driver fails to keep lock between reading data from kfifo into a
dbc request buffer, and queuing the request to the transfer ring.

This allows completed request to re-queue itself in the middle of
an ongoing transfer loop, forcing itself between a kfifo read and
request TRB write of another request

cpu0					cpu1 (re-queue completed req2)

lock(port_lock)
dbc_start_tx()
kfifo_out(fifo, req1->buffer)
unlock(port_lock)
					lock(port_lock)
					dbc_write_complete(req2)
					dbc_start_tx()
      					kfifo_out(fifo, req2->buffer)
					unlock(port_lock)
					lock(port_lock)
					req2->trb = ring->enqueue;
					ring->enqueue++
					unlock(port_lock)
lock(port_lock)
req1->trb = ring->enqueue;
ring->enqueue++
unlock(port_lock)

In the above scenario a kfifo containing "12345678" would read "1234" to
req1 and "5678" to req2, but req2 is queued before req1 leading to
data being transmitted as "56781234"

Solve this by adding a flag that prevents starting a new tx if we
are already mid dbc_start_tx() during the unlocked part.

The already running dbc_do_start_tx() will make sure the newly completed
request gets re-queued as it is added to the request write_pool while
holding the lock.

afc0e34f16 usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths
commit e4037689a366743c4233966f0e74bc455820d316 upstream.

This patch addresses a race condition caused by unsynchronized
execution of multiple call paths invoking `dwc3_remove_requests()`,
leading to premature freeing of USB requests and subsequent crashes.

Three distinct execution paths interact with `dwc3_remove_requests()`:
Path 1:
Triggered via `dwc3_gadget_reset_interrupt()` during USB reset
handling. The call stack includes:
- `dwc3_ep0_reset_state()`
- `dwc3_ep0_stall_and_restart()`
- `dwc3_ep0_out_start()`
- `dwc3_remove_requests()`
- `dwc3_gadget_del_and_unmap_request()`

Path 2:
Also initiated from `dwc3_gadget_reset_interrupt()`, but through
`dwc3_stop_active_transfers()`. The call stack includes:
- `dwc3_stop_active_transfers()`
- `dwc3_remove_requests()`
- `dwc3_gadget_del_and_unmap_request()`

Path 3:
Occurs independently during `adb root` execution, which triggers
USB function unbind and bind operations. The sequence includes:
- `gserial_disconnect()`
- `usb_ep_disable()`
- `dwc3_gadget_ep_disable()`
- `dwc3_remove_requests()` with `-ESHUTDOWN` status

Path 3 operates asynchronously and lacks synchronization with Paths
1 and 2. When Path 3 completes, it disables endpoints and frees 'out'
requests. If Paths 1 or 2 are still processing these requests,
accessing freed memory leads to a crash due to use-after-free conditions.

To fix this added check for request completion and skip processing
if already completed and added the request status for ep0 while queue.

e3a55221f4 usb: uas: fix urb unmapping issue when the uas device is remove during ongoing data transfer
commit 26d56a9fcb2014b99e654127960aa0a48a391e3c upstream.

When a UAS device is unplugged during data transfer, there is
a probability of a system panic occurring. The root cause is
an access to an invalid memory address during URB callback handling.
Specifically, this happens when the dma_direct_unmap_sg() function
is called within the usb_hcd_unmap_urb_for_dma() interface, but the
sg->dma_address field is 0 and the sg data structure has already been
freed.

The SCSI driver sends transfer commands by invoking uas_queuecommand_lck()
in uas.c, using the uas_submit_urbs() function to submit requests to USB.
Within the uas_submit_urbs() implementation, three URBs (sense_urb,
data_urb, and cmd_urb) are sequentially submitted. Device removal may
occur at any point during uas_submit_urbs execution, which may result
in URB submission failure. However, some URBs might have been successfully
submitted before the failure, and uas_submit_urbs will return the -ENODEV
error code in this case. The current error handling directly calls
scsi_done(). In the SCSI driver, this eventually triggers scsi_complete()
to invoke scsi_end_request() for releasing the sgtable. The successfully
submitted URBs, when being unlinked to giveback, call
usb_hcd_unmap_urb_for_dma() in hcd.c, leading to exceptions during sg
unmapping operations since the sg data structure has already been freed.

This patch modifies the error condition check in the uas_submit_urbs()
function. When a UAS device is removed but one or more URBs have already
been successfully submitted to USB, it avoids immediately invoking
scsi_done() and save the cmnd to devinfo->cmnd array. If the successfully
submitted URBs is completed before devinfo->resetting being set, then
the scsi_done() function will be called within uas_try_complete() after
all pending URB operations are finalized. Otherwise, the scsi_done()
function will be called within uas_zap_pending(), which is executed after
usb_kill_anchored_urbs().

The error handling only takes effect when uas_queuecommand_lck() calls
uas_submit_urbs() and returns the error value -ENODEV . In this case,
the device is disconnected, and the flow proceeds to uas_disconnect(),
where uas_zap_pending() is invoked to call uas_try_complete().

04a8a6393f usb: storage: sddr55: Reject out-of-bound new_pba
commit b59d4fda7e7d0aff1043a7f742487cb829f5aac1 upstream.

Discovered by Atuin - Automated Vulnerability Discovery Engine.

new_pba comes from the status packet returned after each write.
A bogus device could report values beyond the block count derived
from info->capacity, letting the driver walk off the end of
pba_to_lba[] and corrupt heap memory.

Reject PBAs that exceed the computed block count and fail the
transfer so we avoid touching out-of-range mapping entries.

cb1401b5bc usb: storage: Fix memory leak in USB bulk transport
commit 41e99fe2005182139b1058db71f0d241f8f0078c upstream.

A kernel memory leak was identified by the 'ioctl_sg01' test from Linux
Test Project (LTP). The following bytes were mainly observed: 0x53425355.

When USB storage devices incorrectly skip the data phase with status data,
the code extracts/validates the CSW from the sg buffer, but fails to clear
it afterwards. This leaves status protocol data in srb's transfer buffer,
such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can
lead to USB protocols leaks to user space through SCSI generic (/dev/sg*)
interfaces, such as the one seen here when the LTP test requested 512 KiB.

Fix the leak by zeroing the CSW data in srb's transfer buffer immediately
after the validation of devices that skip data phase.

Note: Differently from CVE-2018-1000204, which fixed a big leak by zero-
ing pages at allocation time, this leak occurs after allocation, when USB
protocol data is written to already-allocated sg pages.

The issue occurs because usbhs_sys_function_pullup(), which accesses the IP
registers, is executed after the USBHS clocks have been disabled. The
problem is reproducible on the Renesas RZ/G3S SoC starting with the
addition of module stop in the clock enable/disable APIs. With module stop
functionality enabled, a bus error is expected if a master accesses a
module whose clock has been stopped and module stop activated.

Disable the IP clocks at the end of remove.

commit e4f5ce990818d37930cd9fb0be29eee0553c59d9 upstream.

The existing code did not handle the failure case of usb_ep_queue in the
command path, potentially leading to memory leaks.

Improve error handling to free all allocated resources on usb_ep_queue
failure. This patch continues to use goto logic for error handling, as the
existing error handling is complex and not easily adaptable to auto-cleanup
helpers.

993bfdc384 most: usb: fix double free on late probe failure
commit baadf2a5c26e802a46573eaad331b427b49aaa36 upstream.

The MOST subsystem has a non-standard registration function which frees
the interface on registration failures and on deregistration.

This unsurprisingly leads to bugs in the MOST drivers, and a couple of
recent changes turned a reference underflow and use-after-free in the
USB driver into several double free and a use-after-free on late probe
failures.

ce318ec986 mptcp: clear scheduled subflows on retransmit
commit 27fd02860164bfa78cec2640dfad630d832e302c upstream.

When __mptcp_retrans() kicks-in, it schedules one or more subflows for
retransmission, but such subflows could be actually left alone if there
is no more data to retransmit and/or in case of concurrent fallback.

Scheduled subflows could be processed much later in time, i.e. when new
data will be transmitted, leading to bad subflow selection.

Explicitly clear all scheduled subflows before leaving the
retransmission function.

4c257170c8 drivers/usb/dwc3: fix PCI parent check
commit 40f8d17eed7533ed2bbb5e3cc680049b19411b2e upstream.

The sysdev_is_parent check was being used to infer PCI devices that have
the DMA mask set from the PCI capabilities, but sysdev_is_parent is also
used for non-PCI ACPI devices in which case the DMA mask would be the
bus default or as set by the _DMA method.

Without this fix the DMA mask would default to 32-bits and so allocation
would fail if there was no DRAM below 4GB.

Fixes: 47ce45906c ("usb: dwc3: leave default DMA for PCI devices")

f8d1f16628 dm-verity: fix unreliable memory allocation
commit fe680d8c747f4e676ac835c8c7fb0f287cd98758 upstream.

GFP_NOWAIT allocation may fail anytime. It needs to be changed to
GFP_NOIO. There's no need to handle an error because mempool_alloc with
GFP_NOIO can't fail.

5a3f3e39b1 ceph: fix crash in process_v2_sparse_read() for encrypted directories
commit 43962db4a6f593903340c85591056a0cef812dfd upstream.

The crash in process_v2_sparse_read() for fscrypt-encrypted directories
has been reported. Issue takes place for Ceph msgr2 protocol in secure
mode. It can be reproduced by the steps:

sudo mount -t ceph :/ /mnt/cephfs/ -o name=admin,fs=cephfs,ms_mode=secure

(1) mkdir /mnt/cephfs/fscrypt-test-3
(2) cp area_decrypted.tar /mnt/cephfs/fscrypt-test-3
(3) fscrypt encrypt --source=raw_key --key=./my.key /mnt/cephfs/fscrypt-test-3
(4) fscrypt lock /mnt/cephfs/fscrypt-test-3
(5) fscrypt unlock --key=my.key /mnt/cephfs/fscrypt-test-3
(6) cat /mnt/cephfs/fscrypt-test-3/area_decrypted.tar
(7) Issue has been triggered

==================================================================

First of all, we have warning in get_bvec_at() because
cursor->total_resid contains zero value. And, finally,
we have crash in ceph_msg_data_advance() because
cursor->data is NULL. It means that get_bvec_at()
receives not initialized ceph_msg_data_cursor structure
because data is NULL and total_resid contains zero.

Moreover, we don't have likewise issue for the case of
Ceph msgr1 protocol because ceph_msg_data_cursor_init()
has been called before reading sparse data.

This patch adds calling of ceph_msg_data_cursor_init()
in the beginning of process_v2_sparse_read() with
the goal to guarantee that logic of reading sparse data
works correctly for the case of Ceph msgr2 protocol.

commit 76544beea7cfe5bcce6d60f53811657b88ec8be1 upstream.

Reading the interrupt register `SUN4I_REG_INT_ADDR` causes all of its bits
to be reset. If we ever reach the condition of handling more than
`SUN4I_CAN_MAX_IRQ` IRQs, we will have read the register and reset all its
bits but without actually handling the interrupt inside of the loop body.

This may, among other issues, cause us to never `netif_wake_queue()` again
after a transmission interrupt.

9917ba597c atm/fore200e: Fix possible data race in fore200e_open()
commit 82fca3d8a4a34667f01ec2351a607135249c9cff upstream.

Protect access to fore200e->available_cell_rate with rate_mtx lock in the
error handling path of fore200e_open() to prevent a data race.

The field fore200e->available_cell_rate is a shared resource used to track
available bandwidth. It is concurrently accessed by fore200e_open(),
fore200e_close(), and fore200e_change_qos().

In fore200e_open(), the lock rate_mtx is correctly held when subtracting
vcc->qos.txtp.max_pcr from available_cell_rate to reserve bandwidth.
However, if the subsequent call to fore200e_activate_vcin() fails, the
function restores the reserved bandwidth by adding back to
available_cell_rate without holding the lock.

This introduces a race condition because available_cell_rate is a global
device resource shared across all VCCs. If the error path in
fore200e_open() executes concurrently with operations like
fore200e_close() or fore200e_change_qos() on other VCCs, a
read-modify-write race occurs.

Specifically, the error path reads the rate without the lock. If another
CPU acquires the lock and modifies the rate (e.g., releasing bandwidth in
fore200e_close()) between this read and the subsequent write, the error
path will overwrite the concurrent update with a stale value. This results
in incorrect bandwidth accounting.

commit 1b03346314b791ad966d3c6d59253328226a2b2d upstream.

The i.MX6UL reference manual lists two possible interrupt lines for
SAI3 (56 and 57, offset +32). The current device tree entry uses
the first one (24), which prevents IRQs from being handled properly.

Use the second interrupt line (25), which does allow interrupts
to work as expected.

commit 841ecc979b18d3227fad5e2d6a1e6f92688776b5 upstream.

Owing to Config4.MMUSizeExt and VTLB/FTLB MMU features later MIPSr2+
cores can have more than 64 TLB entries.  Therefore allocate an array
for uniquification instead of placing too an small array on the stack.

135713cd07 MIPS: mm: Prevent a TLB shutdown on initial uniquification
commit 9f048fa487409e364cf866c957cf0b0d782ca5a3 upstream.

Depending on the particular CPU implementation a TLB shutdown may occur
if multiple matching entries are detected upon the execution of a TLBP
or the TLBWI/TLBWR instructions.  Given that we don't know what entries
we have been handed we need to be very careful with the initial TLB
setup and avoid all these instructions.

Therefore read all the TLB entries one by one with the TLBR instruction,
bypassing the content addressing logic, and truncate any large pages in
place so as to avoid a case in the second step where an incoming entry
for a large page at a lower address overlaps with a replacement entry
chosen at another index.  Then preinitialize the TLB using addresses
outside our usual unique range and avoiding clashes with any entries
received, before making the usual call to local_flush_tlb_all().

This fixes (at least) R4x00 cores if TLBP hits multiple matching TLB
entries (SGI IP22 PROM for examples sets up all TLBs to the same virtual
address).

Use correct argument to iio_str_to_fixpoint() to parse 3 decimal places.

iio_str_to_fixpoint() has a bit of an unintuitive API where the
fract_mult parameter is the multiplier of the first decimal place as if
it was already an integer.  So to get 3 decimal places, fract_mult must
be 100 rather than 1000.

commit 3aa385a9c75c09b59dcab2ff76423439d23673ab upstream.

The code in bmc150-accel-core.c unconditionally calls
bmc150_accel_set_interrupt() in the iio_buffer_setup_ops,
such as on the runtime PM resume path giving a kernel
splat like this if the device has no interrupts:

Unable to handle kernel NULL pointer dereference at virtual
  address 00000001 when read

PC is at bmc150_accel_set_interrupt+0x98/0x194
LR is at __pm_runtime_resume+0x5c/0x64

This bug seems to have been in the driver since the beginning,
but it only manifests recently, I do not know why.

Store the IRQ number in the state struct, as this is a common
pattern in other drivers, then use this to determine if we have
IRQ support or not.

a8f6a8256a iio:common:ssp_sensors: Fix an error handling path ssp_probe()
commit 21553258b94861a73d7f2cf15469d69240e1170d upstream.

If an error occurs after a successful mfd_add_devices() call, it should be
undone by a corresponding mfd_remove_devices() call, as already done in the
remove function.
