driver fails
commit 163be6ff7739b12ff300d77897d340f661821da2 upstream.
If a gadget driver is in the pending drivers list, a UDC
becomes available and udc_bind_to_driver() fails, then it
gets deleted from the pending list.
i.e. list_del(&driver->pending) in check_pending_gadget_drivers().
Then if that gadget driver is unregistered,
usb_gadget_unregister_driver() does a list_del(&driver->pending)
again thus causing a page fault as that list entry has been poisoned
by the previous list_del().
Fix this by using list_del_init() instead of list_del() in
check_pending_gadget_drivers().
Test case:
- Make sure no UDC is available
- modprobe g_mass_storage file=wrongfile
- Load UDC driver so it becomes available
lun0: unable to open backing file: wrongfile
- modprobe -r g_mass_storage

As soon as the netdev is registers, the kernel can start using the

[ Upstream commit 25382b991d252aed961cd434176240f9de6bb15f ]
The EPHY integrated into the 40nm Set-Top Box devices can falsely
detect energy when connected to a disabled peer interface. When the
peer interface is enabled the EPHY will detect and report the link
as active, but on occasion may get into a state where it is not
able to exchange data with the connected GENET MAC. This issue has
not been observed when the link parameters are auto-negotiated;
however, it has been observed with a manually configured link.
It has been empirically determined that issuing a soft reset to the
EPHY when energy is detected prevents it from getting into this bad
state.

When commit 28b2e0d2cd13 ("net: phy: remove parameter new_link from

phydev->link state from the MAC before invoking phy_mac_interrupt().
However, once commit 88d6272acaaa ("net: phy: avoid unneeded MDIO

the proper determination of the connection parameters by the function
genphy_read_status().

[ Upstream commit 534e7366f41b0c689b01af4375aefcd1462adedf ]
Ethtool self test contains a test for link speed. This test reads the
PTYS register and determines whether the current speed is valid or not.
Change current implementation to use the function mlx5e_port_linkspeed()
that does the same check and fails when speed is invalid. This code
redundancy lead to a bug when mlx5e_port_linkspeed() was updated with
expended speeds and the self test was not.

[ Upstream commit 9df86bdb6746d7fcfc2fda715f7a7c3d0ddb2654 ]
When CQE compression is enabled, compressed CQEs use the following
structure: a title is followed by one or many blocks, each containing 8
mini CQEs (except the last, which may contain fewer mini CQEs).
Due to NAPI budget restriction, a complete structure is not always
parsed in one NAPI run, and some blocks with mini CQEs may be deferred
to the next NAPI poll call - we have the mlx5e_decompress_cqes_cont call
in the beginning of mlx5e_poll_rx_cq. However, if the budget is
extremely low, some blocks may be left even after that, but the code
that follows the mlx5e_decompress_cqes_cont call doesn't check it and
assumes that a new CQE begins, which may not be the case. In such cases,
random memory corruptions occur.
An extremely low NAPI budget of 8 is used when busy_poll or busy_read is
active.
This commit adds a check to make sure that the previous compressed CQE
has been completely parsed after mlx5e_decompress_cqes_cont, otherwise
it prevents a new CQE from being fetched in the middle of a compressed
CQE.
This commit fixes random crashes in __build_skb, __page_pool_put_page
and other not-related-directly places, that used to happen when both CQE
compression and busy_poll/busy_read were enabled.

[ Upstream commit e19868efea0c103f23b4b7e986fd0a703822111f ]
Prior to this patch, the amount of counters guaranteed per VF in the
resource tracker was MLX4_VF_COUNTERS_PER_PORT * MLX4_MAX_PORTS. It was
set regardless if the VF was single or dual port.
This caused several VFs to have no guaranteed counters although the
system could satisfy their request.
The fix is to dynamically guarantee counters, based on each VF
specification.

[ Upstream commit 88824e3bf29a2fcacfd9ebbfe03063649f0f3254 ]
We are calling the checksum helper after the dma_map_single()
call to map the packet. This is incorrect as the checksumming
code will touch the packet from the CPU. This means the cache
won't be properly flushes (or the bounce buffering will leave
us with the unmodified packet to DMA).
This moves the calculation of the checksum & vlan tags to
before the DMA mapping.
This also has the side effect of fixing another bug: If the
checksum helper fails, we goto "drop" to drop the packet, which
will not unmap the DMA mapping.

Since it became possible for the DSA core to use a CPU port different
than 8, our bcm_sf2_imp_setup() function was broken because it assumes
that registers are applicable to port 8. In particular, the port's MAC
is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS
bits if we are not configured for port 8.

[ Upstream commit a904a0693c189691eeee64f6c6b188bd7dc244e9 ]
Historically linux tried to stick to RFC 791, 1122, 2003
for IPv4 ID field generation.
RFC 6864 made clear that no matter how hard we try,
we can not ensure unicity of IP ID within maximum
lifetime for all datagrams with a given source
address/destination address/protocol tuple.
Linux uses a per socket inet generator (inet_id), initialized
at connection startup with a XOR of 'jiffies' and other
fields that appear clear on the wire.
Thiemo Nagel pointed that this strategy is a privacy
concern as this provides 16 bits of entropy to fingerprint
devices.
Let's switch to a random starting point, this is just as
good as far as RFC 6864 is concerned and does not leak
anything critical.

This was preceded by us timing out everything and shutting down the
sockets for the device. The problem is we had a request in the queue at
the same time, so we completed the request twice. This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.
Fix this by checking cmd->status in nbd_read_stat. We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.
For the clear_req cause this is initiated by the user, so again is safe.

[ Upstream commit 6d6b0d0d5afc8c4c84b08261260ba11dfa5206f2 ]
When in slave mode, an arbitration loss (ARLO) may be detected before the
slave had a chance to detect the stop condition (STOPF in ISR).
This is seen when two master + slave adapters switch their roles. It
provokes the i2c bus to be stuck, busy as SCL line is stretched.
- the I2C_SLAVE_STOP event is never generated due to STOPF flag is set but
don't generate an irq (race with ARLO irq, STOPIE is masked). STOPF flag
remains set until next master xfer (e.g. when STOPIE irq get unmasked).
In this case, completion is generated too early: immediately upon new
transfer request (then it doesn't send all data).
- Some data get stuck in TXDR register. As a consequence, the controller
stretches the SCL line: the bus gets busy until a future master transfer
triggers the bus busy / recovery mechanism (this can take time... and
may never happen at all)
So choice is to let the STOPF being detected by the slave isr handler,
to properly handle this stop condition. E.g. don't mask IRQs in error
handler, when the slave is running.

[ Upstream commit 8424312516e5d9baeeb0a95d0e4523579b7aa395 ]
On a system without Single VMOVP support (say GITS_TYPER.VMOVP == 0),
we will map vPEs only on ITSs that will actually control interrupts
for the given VM. And when moving a vPE, the VMOVP command will be
issued only for those ITSs.
But when issuing VMOVPs we seemed fail to present the exact ITSList
to ITSs who are actually included in the synchronization operation.
The its_list_map we're currently using includes all ITSs in the system,
even though some of them don't have the corresponding vPE mapping at all.
Introduce get_its_list() to get the per-VM its_list_map, to indicate
which ITSs have vPE mappings for the given VM, and use this map as
the expected ITSList when building VMOVP. This is hopefully a performance
gain not to do some synchronization with those unsuspecting ITSs.
And initialize the whole command descriptor to zero at beginning, since
the seq_num and its_list should be RES0 when GITS_TYPER.VMOVP == 1.

The driver would fail to deregister and its class device and free
related resources on late probe errors.

commit e6f4e274c1e52d1f0bfe293fb44ddf59de6c0374 upstream.
The vega10_odn_update_soc_table() function does not allow the SCLK
dependent voltage to be set for power-state 7 to a value below the default
in pptable. Change the for-loop condition to allow undervolting in the
highest state.

commit bacdcb6675e170bb2e8d3824da220e10274f42a7 upstream.
Yegor Yefremov <yegorslists@googlemail.com> reported that musb and ftdi
uart can fail for the first open of the uart unless connected using
a hub.
This is because the first dma call done by musb_ep_program() must wait
if cppi41 is PM runtime suspended. Otherwise musb_ep_program() continues
with other non-dma packets before the DMA transfer is started causing at
least ftdi uarts to fail to receive data.
Let's fix the issue by waking up cppi41 with PM runtime calls added to
cppi41_dma_prep_slave_sg() and return NULL if still idled. This way we
have musb_ep_program() continue with PIO until cppi41 is awake.

commit 7667819385457b4aeb5fac94f67f52ab52cc10d5 upstream.
bam_dma_terminate_all() will leak resources if any of the transactions are
committed to the hardware (present in the desc fifo), and not complete.
Since bam_dma_terminate_all() does not cause the hardware to be updated,
the hardware will still operate on any previously committed transactions.
This can cause memory corruption if the memory for the transaction has been
reassigned, and will cause a sync issue between the BAM and its client(s).
Fix this by properly updating the hardware in bam_dma_terminate_all().

commit 8c55dedb795be8ec0cf488f98c03a1c2176f7fb1 upstream.
Nicolas Waisman noticed that even though noa_len is checked for
a compatible length it's still possible to overrun the buffers
of p2pinfo since there's no check on the upper bound of noa_num.
Bound noa_num against P2P_MAX_NOA_NUM.

commit b3a81c777dcb093020680490ab970d85e2f6f04f upstream.
On HID report descriptor parsing error the code displays bogus
pointer instead of error offset (subtracts start=NULL from end).
Make the message more useful by displaying correct error offset
and include total buffer size for reference.
This was carried over from ancient times - "Fixed" commit just
promoted the message from DEBUG to ERROR.

commit d9d4b1e46d9543a82c23f6df03f4ad697dab361b upstream.
The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff
driver. The problem is caused by the driver's assumption that the
device must have an input report. While this will be true for all
normal HID input devices, a suitably malicious device can violate the
assumption.
The same assumption is present in over a dozen other HID drivers.
This patch fixes them by checking that the list of hid_inputs for the
hid_device is nonempty before allowing it to be used.

commit 09f3dbe474735df13dd8a66d3d1231048d9b373f upstream.
The Primebook C11B uses the SIPODEV SP1064 touchpad. There are 2 versions
of this 2-in-1 and the touchpad in the older version does not supply
descriptors, so it has to be added to the override list.
