syzbot found that tcf_skbmod_dump() was copying four bytes
from kernel stack to user space [1].
The issue here is that 'struct tc_skbmod' has a four bytes hole.
We need to clear the structure before filling fields.

After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset is not executed from bind operation and
mac address is not read from the device registers or the devicetree at that
moment. Since the check to configure if the assigned mac address is random
or not for the interface, happens after the bind operation from
usbnet_probe, the interface keeps configured as random address, although the
address is correctly read and set during open operation (the only reset
now).
In order to keep only one reset for the device and to avoid the interface
always configured as random address, after reset, configure correctly the
suitable field from the driver, if the mac address is read successfully from
the device registers or the devicetree. Take into account if a locally
administered address (random) was previously stored.

Unique discovery NQNs allow to differentiate between discovery
services from (typically physically separate) NVMe-oF subsystems.
This is required for establishing secured connections as otherwise

When the write is accepted, the kernel deletes all current timers and
reinits all banks.
Doing that in parallel can lead to initializing a timer which is already
armed and in the timer wheel, i.e., in use already:
ODEBUG: init active (active state 0) object: ffff888063a28000 object

Subject: [PATCH] drm/panfrost: Fix the error path in
panfrost_mmu_map_fault_addr()
If some the pages or sgt allocation failed, we shouldn't release the
pages ref we got earlier, otherwise we will end up with unbalanced
get/put_pages() calls. We should instead leave everything in place
and let the BO release function deal with extra cleanup when the object
is destroyed, or let the fault handler try again next time it's called.

The incompatible device in my possession has a sticker that says

This device is a gray USB parallel port adapter with "F5U002" imprinted
on the plastic and a sticker that says both "F5U002" and "P80453-A".
It's identified in lsusb as "05ab:1001 In-System Design BAYI Printer
Class Support". It's subtly different from the other gray cable I have
that has "F5U002 Rev 2" and "P80453-B" on its sticker and device ID
050d:0002.

Some PPM implementation do not like UCSI_ACK_CONNECTOR_CHANGE
without UCSI_ACK_COMMAND_COMPLETE. Moreover, doing this is racy
as it requires sending two UCSI_ACK_CC_CI commands in a row and
the second one will be started with UCSI_CCI_ACK_COMPLETE already

We need to take into account that a line's consumer label may be NULL
and not try to kstrdup() it in that case but rather pass the NULL
pointer up the stack to the interrupt request function.
To that end: let make_irq_label() return NULL as a valid return value
and use ERR_PTR() instead to signal an allocation failure to callers.

When ncm function is working and then stop usb0 interface for link down,
eth_stop() is called. At this piont, accidentally if usb transport error
should happen in usb_ep_enable(), 'in_ep' and/or 'out_ep' may not be enabled.
After that, ncm_disable() is called to disable for ncm unbind
but gether_disconnect() is never called since 'in_ep' is not enabled.
As the result, ncm object is released in ncm unbind
but 'dev->port_usb' associated to 'ncm->port' is not NULL.
And when ncm bind again to recover netdev, ncm object is reallocated
but usb0 interface is already associated to previous released ncm object.
Therefore, once usb0 interface is up and eth_start_xmit() is called,
released ncm object is dereferrenced and it might cause use-after-free memory.
[function unlink via configfs]
usb0: eth_stop dev->port_usb=ffffff9b179c3200
--> error happens in usb_ep_enable().
NCM: ncm_disable: ncm=ffffff9b179c3200
--> no gether_disconnect() since ncm->port.in_ep->enabled is false.
NCM: ncm_unbind: ncm unbind ncm=ffffff9b179c3200
NCM: ncm_free: ncm free ncm=ffffff9b179c3200 <-- released ncm
[function link via configfs]
NCM: ncm_alloc: ncm alloc ncm=ffffff9ac4f8a000
NCM: ncm_bind: ncm bind ncm=ffffff9ac4f8a000
NCM: ncm_set_alt: ncm=ffffff9ac4f8a000 alt=0
usb0: eth_open dev->port_usb=ffffff9b179c3200 <-- previous released ncm
usb0: eth_start dev->port_usb=ffffff9b179c3200 <--
eth_start_xmit()
--> dev->wrap()
Unable to handle kernel paging request at virtual address dead00000000014f
This patch addresses the issue by checking if 'ncm->netdev' is not NULL at
ncm_disable() to call gether_disconnect() to deassociate 'dev->port_usb'.
It's more reasonable to check 'ncm->netdev' to call gether_connect/disconnect
rather than check 'ncm->port.in_ep->enabled' since it might not be enabled
but the gether connection might be established.

Off-by-one errors happen because nr_snk_pdo and nr_src_pdo are
incorrectly added one. The index of the loop is equal to the number of
PDOs to be updated when leaving the loop and it doesn't need to be added
one.
When doing the power negotiation, TCPM relies on the "nr_snk_pdo" as
the size of the local sink PDO array to match the Source capabilities
of the partner port. If the off-by-one overflow occurs, a wrong RDO
might be sent and unexpected power transfer might happen such as over
voltage or over current (than expected).
"nr_src_pdo" is used to set the Rp level when the port is in Source
role. It is also the array size of the local Source capabilities when
filling up the buffer which will be sent as the Source PDOs (such as
in Power Negotiation). If the off-by-one overflow occurs, a wrong Rp
level might be set and wrong Source PDOs will be sent to the partner
port. This could potentially cause over current or port resets.

Jan Schunk reports that his small NFS servers suffer from memory
exhaustion after just a few days. A bisect shows that commit
e18e157bb5c8 ("SUNRPC: Send RPC message on TCP with a single
sock_sendmsg() call") is the first bad commit.
That commit assumed that sock_sendmsg() releases all the pages in
the underlying bio_vec array, but the reality is that it doesn't.
svc_xprt_release() releases the rqst's response pages, but the
record marker page fragment isn't one of those, so it is never
released.
This is a narrow fix that can be applied to stable kernels. A
more extensive fix is in the works.

Preempt fences can sleep waiting for an exec queue suspend operation to
complete. If the system_unbound_wq is used for waiting and the number of
waiters exceeds max_active this will result in other users of the
system_unbound_wq getting starved. Use a device private work queue for
preempt fences to avoid starvation of the system_unbound_wq.
Even though suspend operations can complete out-of-order, all suspend
operations within a VM need to complete before the preempt rebind worker
can start. With that, use a device private ordered wq for preempt fence
waiting.

For each rebind we insert a GuC TLB invalidation and add a
corresponding unordered TLB invalidation fence. This might
add a huge number of TLB invalidation fences to wait for so
rather than doing that, defer the TLB invalidation to the
next ring ops for each affected exec queue. Since the TLB
is invalidated on exec_queue switch, we need to invalidate
once for each affected exec_queue.

There is a misinterpretation of some of the PIN_CONFIG_* options in this
driver library. PIN_CONFIG_OUTPUT_ENABLE should refer to a buffer or
switch in the output direction of the electrical path. The MediaTek
hardware does not have such a thing. The driver incorrectly maps this
option to the GPIO function's direction.
Likewise, PIN_CONFIG_INPUT_ENABLE should refer to a buffer or switch in
the input direction. The hardware does have such a mechanism, and is
mapped to the IES bit. The driver however sets the direction in addition
to the IES bit, which is incorrect. On readback, the IES bit isn't even
considered.
Ironically, the driver does not support readback for PIN_CONFIG_OUTPUT,
while its readback of PIN_CONFIG_{INPUT,OUTPUT}_ENABLE is what it should
be doing for PIN_CONFIG_OUTPUT.
Rework support for these three options, so that PIN_CONFIG_OUTPUT_ENABLE
is completely removed, PIN_CONFIG_INPUT_ENABLE is only linked to the IES
bit, and PIN_CONFIG_OUTPUT is linked to the GPIO function's direction
and output level.

In the generic pin config library, readback of some options are handled
differently compared to the setting of those options: the argument value
is used to convey enable/disable of an option in the set path, but
success or -EINVAL is used to convey if an option is enabled or disabled
in the debugfs readback path.
PIN_CONFIG_INPUT_SCHMITT_ENABLE is one such option. Fix the readback of
the option in the mediatek-paris library, so that the debugfs dump is
not showing "input schmitt enabled" for pins that don't have it enabled.

Instead of bailing when fences have already been installed on the
DMABUF, wait for them (with a timeout) when doing a blocking operation.
This fixes the issue where userspace would submit a DMABUF with fences
already installed, with the (correct) expectation that it would just
work.

A "read" fence was installed when the DMABUF was to be written to,
and a "write" fence was installed when the DMABUF was to be read from.
Besides, dma_resv_usage_rw() should only be used when waiting for
fences.

Fix issues when initially checking for a connector change:
- Use the correct connector number not the entire CCI.
- Call ->read under the PPM lock.
- Remove a bogus READ_ONCE.
