commit d0f6cfb2bd165b0aa307750e07e03420859bd554 upstream.
Control Flow Integrity (CFI) instrumentation of the kernel noticed that
the caller, dev_attr_show(), and the callback, odvp_show(), did not have
matching function prototypes, which would cause a CFI exception to be
raised. Correct the prototype by using struct device_attribute instead
of struct kobj_attribute.

[ Upstream commit 4bfe744ff1644fbc0a991a2677dc874475dd6776 ]
I had this bug sitting for too long in my pile, it is time to fix it.
Thanks to Doug Porter for reminding me of it!
We had various attempts in the past, including commit
0cbe6a8f089e ("tcp: remove SOCK_QUEUE_SHRUNK"),
but the issue is that TCP stack currently only generates
EPOLLOUT from input path, when tp->snd_una has advanced
and skb(s) cleaned from rtx queue.
If a flow has a big RTT, and/or receives SACKs, it is possible
that the notsent part (tp->write_seq - tp->snd_nxt) reaches 0
and no more data can be sent until tp->snd_una finally advances.
What is needed is to also check if POLLOUT needs to be generated
whenever tp->snd_nxt is advanced, from output path.
This bug triggers more often after an idle period, as
we do not receive ACK for at least one RTT. tcp_notsent_lowat
could be a fraction of what CWND and pacing rate would allow to
send during this RTT.
In a followup patch, I will remove the bogus call
to tcp_chrono_stop(sk, TCP_CHRONO_SNDBUF_LIMITED)
from tcp_check_space(). Fact that we have decided to generate
an EPOLLOUT does not mean the application has immediately
refilled the transmit queue. This optimistic call
might have been the reason the bug seemed not too serious.
Tested:
200 ms rtt, 1% packet loss, 32 MB tcp_rmem[2] and tcp_wmem[2]
$ echo 500000 >/proc/sys/net/ipv4/tcp_notsent_lowat

tested against both scenario of having a SGMII interface and one
without.
Without the SGMII PCS TSE adpater, the sgmii_adapter_base address is

commit ab7aa2866d295438dc60522f85c5421c6b4f1507 upstream.
If the PHY controller node has a "port" dwc3 tries to find an
extcon device even when "usb-role-switch" is present. This happens
because dwc3_get_extcon() sees that "port" node and then calls
extcon_find_edev_by_node() which will always return EPROBE_DEFER
in that case.
On the other hand, even if an extcon was present and dwc3_get_extcon()
was successful it would still be ignored in favor of "usb-role-switch".
Let's just first check if "usb-role-switch" is configured in the device
tree and directly use it instead and only try to look for an extcon
device otherwise.

`nf_flowtable_udp_timeout` sysctl option is available only
if CONFIG_NFT_FLOW_OFFLOAD enabled. But infra for this flow
offload UDP timeout was added under CONFIG_NF_FLOW_TABLE
config option. So, if you have CONFIG_NFT_FLOW_OFFLOAD
disabled and CONFIG_NF_FLOW_TABLE enabled, the
`nf_flowtable_udp_timeout` is not present in sysfs.
Please note, that TCP flow offload timeout sysctl option
is present even CONFIG_NFT_FLOW_OFFLOAD is disabled.
I suppose it was a typo in commit that adds UDP flow offload
timeout and CONFIG_NF_FLOW_TABLE should be used instead.

commit e23e50e7acc8d8f16498e9c129db33e6a00e80eb upstream.
The sizeof(struct whitehat_dr_info) can be 4 bytes under CONFIG_AEABI=n
due to "-mabi=apcs-gnu", even though it has a single u8:
whiteheat_private {
__u8 mcr; /* 0 1 */
/* size: 4, cachelines: 1, members: 1 */
/* padding: 3 */
/* last cacheline: 4 bytes */
};
The result is technically harmless, as both the source and the
destinations are currently the same allocation size (4 bytes) and don't
use their padding, but if anything were to ever be added after the
"mcr" member in "struct whiteheat_private", it would be overwritten. The
structs both have a single u8 "mcr" member, but are 4 bytes in padded
size. The memcpy() destination was explicitly targeting the u8 member
(size 1) with the length of the whole structure (size 4), triggering
the memcpy buffer overflow warning:

[ Upstream commit 8de8b71b787f38983d414d2dba169a3bfefa668a ]
While checking AF_XDP copy mode combined with busy poll, strange
results were observed. rxdrop and txonly scenarios worked fine, but
l2fwd broke immediately.
After a deeper look, it turned out that for l2fwd, Tx side was exiting
early due to xsk_no_wakeup() returning true and in the end
xsk_generic_xmit() was never called. Note that AF_XDP Tx in copy mode
is syscall steered, so the current behavior is broken.
Txonly scenario only worked due to the fact that
sk_mark_napi_id_once_xdp() was never called - since Rx side is not in
the picture for this case and mentioned function is called in
xsk_rcv_check(), sk::sk_napi_id was never set, which in turn meant that
xsk_no_wakeup() was returning false (see the sk->sk_napi_id >=
MIN_NAPI_ID check in there).
To fix this, prefer busy poll in xsk_sendmsg() only when zero copy is
enabled on a given AF_XDP socket. By doing so, busy poll in copy mode
would not exit early on Tx side and eventually xsk_generic_xmit() will
be called.

[ Upstream commit a0df71948e9548de819a6f1da68f5f1742258a52 ]
Calling tls_append_frag when max_open_record_len == record->len might
add an empty fragment to the TLS record if the call happens to be on the
page boundary. Normally tls_append_frag coalesces the zero-sized
fragment to the previous one, but not if it's on page boundary.
If a resync happens then, the mlx5 driver posts dump WQEs in
tx_post_resync_dump, and the empty fragment may become a data segment
with byte_count == 0, which will confuse the NIC and lead to a CQE
error.
This commit fixes the described issue by skipping tls_append_frag on
zero size to avoid adding empty fragments. The fix is not in the driver,
because an empty fragment is hardly the desired behavior.

Commit 76821e222c18 ("serial: imx: ensure that RX irqs are off if RX is
off") accidentally enabled overrun interrupts unconditionally when
deferring DMA enable until after the receiver has been enabled during
startup.
Fix this by using the DMA-initialised instead of DMA-enabled flag to
determine whether overrun interrupts should be enabled.
Note that overrun interrupts are already accounted for in
imx_uart_clear_rx_errors() when using DMA since commit 41d98b5da92f
("serial: imx-serial - update RX error counters when DMA is used").

commit 06d5afd4d640eea67f5623e76cd5fc03359b7f3c upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.5.2 describes that the signal octet in
convergence layer type 2 can be either one or two bytes. The length is
encoded in the EA bit. This is set 1 for the last byte in the sequence.
gsmtty_modem_update() handles this correctly but gsm_dlci_data_output()
fails to set EA to 1. There is no case in which we encode two signal octets
as there is no case in which we send out a break signal.
Therefore, always set the EA bit to 1 for the signal octet to fix this.

commit 1ec92e9742774bf42614fceea3bf6b50c9409225 upstream.
The active mux instances are managed in the gsm_mux array and via mux_get()
and mux_put() functions separately. This gives a very loose coupling
between the actual instance and the gsm_mux array which manages it. It also
results in unnecessary lockings which makes it prone to failures. And it
creates a race condition if more than the maximum number of mux instances
are requested while the user changes the parameters of an active instance.
The user may loose ownership of the current mux instance in this case.
Fix this by moving the gsm_mux array handling to the mux allocation and
deallocation functions.

The left speaker of max98373 uses spk_r_endpoint, and right
speaker uses spk_l_endpoint, this is obviously wrong.
This patch corrects the endpoints for max98373 codec.

For GRE and GRETAP devices, currently o_seqno starts from 1 in native
mode. According to RFC 2890 2.2., "The first datagram is sent with a
sequence number of 0." Fix it.
It is worth mentioning that o_seqno already starts from 0 in collect_md
mode, see gre_fb_xmit(), where tunnel->o_seqno is passed to
gre_build_header() before getting incremented.

syzbot complained about a recent change in TCP stack,
hitting a NULL pointer [1]
tcp request sockets have an af_specific pointer, which
was used before the blamed change only for SYNACK generation
in non SYNCOOKIE mode.
tcp requests sockets momentarily created when third packet

Make sure this field is populated, in the same way normal

commit 743b83f15d4069ea57c3e40996bf4a1077e0cdc1 upstream.
Check if the incoming interface is available and NFT_BREAK
in case neither skb->sk nor input device are set.
Because nf_sk_lookup_slow*() assume packet headers are in the
'in' direction, use in postrouting is not going to yield a meaningful
result. Same is true for the forward chain, so restrict the use
to prerouting, input and output.
Use in output work if a socket is already attached to the skb.

Commit 46b5889cc2c5 ("mtd: implement proper partition handling")
started using "mtd_get_master_ofs()" in mtd callbacks to determine
memory offsets by means of 'part' field from mtd_info, what previously
was smashed accessing 'master' field in the mtd_set_dev_defaults() method.
That provides wrong offset what causes hardware access errors.
Just make 'part', 'master' as separate fields, rather than using
union type to avoid 'part' data corruption when mtd_set_dev_defaults()
is called.

commit 456244aeecd54249096362a173dfe06b82a5cafa upstream.
Issue description:
When an OTG port has been switched to device role and then switch back
to host role again, the USB 3.0 Host (XHCI) will not be able to detect
"plug in event of a connected USB 2.0/1.0 ((Highspeed and Fullspeed)
devices until system reboot.
Root cause and Solution:
There is a condition checking flag "ssusb->otg_switch.is_u3_drd" in
toggle_opstate(). At the end of role switch procedure, toggle_opstate()
will be called to set DC_SESSION and SOFT_CONN bit. If "is_u3_drd" was
set and switched the role to USB host 3.0, bit DC_SESSION and SOFT_CONN
will be skipped hence caused the port cannot detect connected USB 2.0
(Highspeed and Fullspeed) devices. Simply remove the condition check to
solve this issue.

[ Upstream commit 0c640d9544d0109da3889d71ae77301e556db977 ]
Commit bf781869e5cf ("ARM: dts: at91: add pinctrl-{names, 0} for all
gpios") introduces pinctrl phandles for pins used by individual
controllers to avoid failures due to commit 2ab73c6d8323 ("gpio:
Support GPIO controllers without pin-ranges"). For SPI controllers
available on SAMA5D4 and SAMA5D3 some of the pins are defined in
SoC specific dtsi on behalf of pinctrl-0. Adding extra pinctrl phandles
on board specific dts also on behalf of pinctrl-0 overwrite the pinctrl-0
phandle specified in SoC specific dtsi. Thus add the board specific
pinctrl to pinctrl-1.
Fixes: bf781869e5cf ("ARM: dts: at91: add pinctrl-{names, 0} for all gpios")
Depends-on: 5c8b49852910 ("ARM: dts: at91: sama5d4_xplained: fix pinctrl phandle name")

commit 4c79865f3e8a2db93ec1e844509edfebe5a6ae56 upstream.
The GW71xx, GW72xx and GW73xx boards have USB1 routed to a USB OTG
connectors and USB2 routed to a USB hub.
The OTG connector has a over-currently protection with an active-low
pin and the USB1 to HUB connection has no over-current protection (as
the HUB itself implements this for its downstream ports).
Add proper dt nodes to specify the over-current pin polarity for USB1
and disable over-current protection for USB2.

[ Upstream commit bc6de2878429e85c1f1afaa566f7b5abb2243eef ]
There is a deadlock in rr_close(), which is shown below:
(Thread 1) | (Thread 2)
| rr_open()
rr_close() | add_timer()
spin_lock_irqsave() //(1) | (wait a time)
... | rr_timer()
del_timer_sync() | spin_lock_irqsave() //(2)
(wait timer to stop) | ...
We hold rrpriv->lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need rrpriv->lock in position (2) of thread 2.
As a result, rr_close() will block forever.
This patch extracts del_timer_sync() from the protection of
spin_lock_irqsave(), which could let timer handler to obtain
the needed lock.

commit bf95c4d4630c7a2c16e7b424fdea5177d9ce0864 upstream.
If any function like UVC is deactivating gadget as part of composition
switch which results in not calling pullup enablement, it is not getting
enabled after switch to new composition due to this deactivation flag
not cleared. This results in USB enumeration not happening after switch
to new USB composition. Hence clear deactivation flag inside gadget
structure in configfs_composite_unbind() before switch to new USB
composition.

This code is really spurious.
It always returns an ERR_PTR, even when err is known to be 0 and calls
put_device() after a successful device_register() call.
It is likely that the return statement in the normal path is missing.
Add 'return rdev;' to fix it.

Currently, there are some querying mailboxes sent from VF to PF,
and VF will wait the PF's handling result. For mailbox
HCLGE_MBX_GET_QID_IN_PF and HCLGE_MBX_GET_RSS_KEY, it may fail
when the input parameter is invalid, but the prototype of their
handler function is void. In this case, PF always return success
to VF, which may cause the VF get incorrect result.
Fixes it by adding return value for these function.

When resuming from system sleep state, restore_processor_state()
restores the boot CPU MSRs. These MSRs could be emulated by microcode.
If microcode is not loaded yet, writing to emulated MSRs leads to
unchecked MSR access error:

commit ff9166c623704337bd6fe66fce2838d9768a6634 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.4.4.2 states that any received unnumbered
acknowledgment (UA) with its poll/final (PF) bit set to 0 shall be
discarded. Currently, all UA frame are handled in the same way regardless
of the PF bit. This does not comply with the standard.
Remove the UA case in gsm_queue() to process only UA frames with PF bit set
to 1 to abide the standard.

[ Upstream commit 9fe4e0d3cbfe90152137963cc024ecb63db6e8e6 ]
According to the datasheet, mt7622 only has 5 ECC capabilities instead
of 7, and the decoding error register is arranged as follows:
+------+---------+---------+---------+---------+
| Bits | 19:15 | 14:10 | 9:5 | 4:0 |
+------+---------+---------+---------+---------+
| Name | ERRNUM3 | ERRNUM2 | ERRNUM1 | ERRNUM0 |
+------+---------+---------+---------+---------+
This means err_mask should be 0x1f instead of 0x3f and the number of
bits shifted in mtk_ecc_get_stats should be 5 instead of 8.
This commit introduces err_shift for the difference in this register
and fix other existing parameters.
Public MT7622 reference manual can be found on [0] and the info this
commit is based on is from page 656 and page 660.

commit 8799ebce84d672aae1dc3170510f6a3e66f96b11 upstream.
Now arch-specific functions all do the same thing. When it fixes the
symbol address it needs to check the boundary between the kernel image
and modules. For the last symbol in the previous region, it cannot
know the exact size as it's discarded already. Thus it just uses a
small page size (4096) and rounds it up like the last symbol.

commit 3f7ce6d7091765ed6c67c5d78aa364b9d17e3aab upstream.
Flexcom3 is used as board console serial. There are no pull-ups on these
lines on the board. This means that if a cable is not connected (that has
pull-ups included), stray characters could appear on the console as the
floating pins voltage levels are interpreted as incoming characters.
To avoid this problem, enable the internal pull-ups on these lines.

Some of the pinmuxing bits described in rk3308_mux_recalced_data are wrong,
pointing to non-existing registers.
Fix the entire table.
Also add a comment in front of each entry with the same string that appears
in the datasheet to make the table easier to compare with the docs.
This fix has been tested on real hardware for the gpio3b3_sel entry.

[ Upstream commit 5b0b9e4c2c895227c8852488b3f09839233bba54 ]
In tcp_create_openreq_child we adjust tcp_header_len for md5 using the
remote address in newsk. But that address is still 0 in newsk at this
point, and it is only set later by the callers (tcp_v[46]_syn_recv_sock).
Use the address from the request socket instead.

It is possible that the recovery work might be running while the freeze
gets executed (during hibernation etc.,). Currently, we don't powerdown
the stack if it is not up but if the recovery work completes after freeze,
then the device will be up afterwards. This will not be a sane situation.
So let's flush the recovery worker before trying to powerdown the device.

commit 31fa985b4196f8a66f027672e9bf2b81fea0417c upstream.
kasan_quarantine_remove_cache() is called in kmem_cache_shrink()/
destroy(). The kasan_quarantine_remove_cache() call is protected by
cpuslock in kmem_cache_destroy() to ensure serialization with
kasan_cpu_offline().
However the kasan_quarantine_remove_cache() call is not protected by
cpuslock in kmem_cache_shrink(). When a CPU is going offline and cache
shrink occurs at same time, the cpu_quarantine may be corrupted by
interrupt (per_cpu_remove_cache operation).
So add a cpu_quarantine offline flags check in per_cpu_remove_cache().

[ Upstream commit 71cffebf6358a7f5031f5b208bbdc1cb4db6e539 ]
Commit 4b5923249b8fa4 ("net: dsa: lantiq_gswip: Configure all remaining
GSWIP_MII_CFG bits") added all known bits in the GSWIP_MII_CFGp
register. It helped bring this register into a well-defined state so the
driver has to rely less on the bootloader to do things right.
Unfortunately it also sets the GSWIP_MII_CFG_RMII_CLK bit without any
possibility to configure it. Upon further testing it turns out that all
boards which are supported by the GSWIP driver in OpenWrt which use an
RMII PHY have a dedicated oscillator on the board which provides the
50MHz RMII reference clock.
Don't set the GSWIP_MII_CFG_RMII_CLK bit (but keep the code which always
clears it) to fix support for the Fritz!Box 7362 SL in OpenWrt. This is
a board with two Atheros AR8030 RMII PHYs. With the "RMII clock" bit set
the MAC also generates the RMII reference clock whose signal then
conflicts with the signal from the oscillator on the board. This results
in a constant cycle of the PHY detecting link up/down (and as a result
of that: the two ports using the AR8030 PHYs are not working).
At the time of writing this patch there's no known board where the MAC
(GSWIP) has to generate the RMII reference clock. If needed this can be
implemented in future by providing a device-tree flag so the
GSWIP_MII_CFG_RMII_CLK bit can be toggled per port.

commit c05d8332f5d23fa3b521911cbe55a2b67fb21248 upstream.
We have now seen panel (XMG Core 15 e21 laptop) advertizing support
for Intel proprietary eDP backlight control via DPCD registers, but
actually working only with legacy pwm control.
This patch adds panel EDID check for possible HDR static metadata and
Intel proprietary eDP backlight control is used only if that exists.
Missing HDR static metadata is ignored if user specifically asks for
Intel proprietary eDP backlight control via enable_dpcd_backlight
parameter.
v2 :
- Ignore missing HDR static metadata if Intel proprietary eDP
backlight control is forced via i915.enable_dpcd_backlight
- Printout info message if panel is missing HDR static metadata and
support for Intel proprietary eDP backlight control is detected
Fixes: 4a8d79901d5b ("drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now)")

[ Upstream commit 942da3af32b2288e674736eb159d1fc676261691 ]
The bootloader for the AM3517 has previously done much of the pin
muxing, but as the bootloader is moving more and more to a model
based on the device tree, it may no longer automatically mux the
pins, so it is necessary to add the pinmuxing to the Linux device
trees so the respective peripherals can remain functional.

2.35.1
From: Daniel Starke <[email protected]>
commit d0bcdffcad5a22f202e3bf37190c0dd8c080ea92 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.7.3 states that the valid range for the
maximum number of retransmissions (N2) is from 0 to 255 (both including).
gsm_config() fails to limit this range correctly. Furthermore,
gsm_control_retransmit() handles this number incorrectly by performing
N2 - 1 retransmission attempts. Setting N2 to zero results in more than 255
retransmission attempts.
Fix the range check in gsm_config() and the value handling in
gsm_control_send() and gsm_control_retransmit() to comply with 3GPP 27.010.

From: Krzysztof Kozlowski <[email protected]>
commit ac875df4d854ab13d9c4af682a1837a1214fecec upstream.
The Samsung pinctrl drivers depend on OF_GPIO, which is part of GPIOLIB.
ARMv7 Exynos platform selects GPIOLIB and Samsung pinctrl drivers. ARMv8
Exynos selects only the latter leading to possible wrong configuration
on ARMv8 build:
WARNING: unmet direct dependencies detected for PINCTRL_EXYNOS
Depends on [n]: PINCTRL [=y] && OF_GPIO [=n] && (ARCH_EXYNOS [=y] || ARCH_S5PV210 || COMPILE_TEST [=y])
Selected by [y]:
- ARCH_EXYNOS [=y]
Always select the GPIOLIB from the Samsung pinctrl drivers to fix the
issue. This requires removing of OF_GPIO dependency (to avoid recursive
dependency), so add dependency on OF for COMPILE_TEST cases.

For IP6GRE and IP6GRETAP devices, currently o_seqno starts from 1 in
native mode. According to RFC 2890 2.2., "The first datagram is sent
with a sequence number of 0." Fix it.
It is worth mentioning that o_seqno already starts from 0 in collect_md
mode, see the "if (tunnel->parms.collect_md)" clause in __gre6_xmit(),
where tunnel->o_seqno is passed to gre_build_header() before getting
incremented.

commit 17eac652028501df7ea296b1d9b9c134db262b7d upstream.
In gsm_cleanup_mux() the muxer is closed down and all queues are removed.
However, removing the queues is done without explicit control of the
underlying buffers. Flush those before freeing up our queues to ensure
that all outgoing queues are cleared consistently. Otherwise, a new mux
connection establishment attempt may time out while the underlying tty is
still busy sending out the remaining data from the previous connection.

[ Upstream commit f5d0f921ea362636e4a2efb7c38d1ead373a8700 ]
because the copychunk_write might cover a region of the file that has not yet
been sent to the server and thus fail.
A simple way to reproduce this is:
truncate -s 0 /mnt/testfile; strace -f -o x -ttT xfs_io -i -f -c 'pwrite 0k 128k' -c 'fcollapse 16k 24k' /mnt/testfile
the issue is that the 'pwrite 0k 128k' becomes rearranged on the wire with
the 'fcollapse 16k 24k' due to write-back caching.
fcollapse is implemented in cifs.ko as a SMB2 IOCTL(COPYCHUNK_WRITE) call
and it will fail serverside since the file is still 0b in size serverside
until the writes have been destaged.
To avoid this we must ensure that we destage any unwritten data to the
server before calling COPYCHUNK_WRITE.

[ Upstream commit 24cbdb910bb62b5be3865275e5682be1a7708c0f ]
The other port_hidden functions rely on the port_read/port_write
functions to access the hidden control port. These functions apply the
offset for port_base_addr where applicable. Update port_hidden_wait to
use the port_wait_bit so that port_base_addr offsets are accounted for
when waiting for the busy bit to change.
Without the offset the port_hidden_wait function would timeout on
devices that have a non-zero port_base_addr (e.g. MV88E6141), however
devices that have a zero port_base_addr would operate correctly (e.g.
MV88E6390).

[ Upstream commit acac0541d1d65e81e599ec399d34d184d2424401 ]
The hardware checksum offloading requires use of a transmit
status block inserted before the outgoing frame data, this was
updated in '9a9ba2a4aaaa ("net: bcmgenet: always enable status blocks")'
However, skb_tx_timestamp() assumes that it is passed a raw frame
and PTP parsing chokes on this status block.
Fix this by calling __skb_pull(), which hides the TSB before calling
skb_tx_timestamp(), so an outgoing PTP packet is parsed correctly.
As the data in the skb has already been set up for DMA, and the
dma_unmap_* calls use a separately stored address, there is no
no effective change in the data transmission.

commit 535bf600de75a859698892ee873521a48d289ec1 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.7.2 states that the maximum frame size
(N1) refers to the length of the information field (i.e. user payload).
However, 'txframe' stores the whole frame including frame header, checksum
and start/end flags. We also need to consider the byte stuffing overhead.
Define constant for the protocol overhead and adjust the 'txframe' size
calculation accordingly to reserve enough space for a complete mux frame
including byte stuffing for advanced option mode. Note that no byte
stuffing is applied to the start and end flag.
Also use MAX_MTU instead of MAX_MRU as this buffer is used for data
transmission.

The stm32_gpio_get() should only be called for LEVEL triggered interrupts,
skip calling it for EDGE triggered interrupts altogether to avoid wasting
CPU cycles in EOI handler. On this platform, EDGE triggered interrupts are
the majority and LEVEL triggered interrupts are the exception no less, and
the CPU cycles are not abundant.

[ Upstream commit 7e842d70fe599bc13594b650b2144c4b6e6d6bf1 ]
HyperFlash devices fail to probe:
rpc-if-hyperflash rpc-if-hyperflash: probing of hyperbus device failed
In HyperFlash or Octal-SPI Flash mode, the Transfer Data Enable bits
(SPIDE) in the Manual Mode Enable Setting Register (SMENR) are derived
from half of the transfer size, cfr. the rpcif_bits_set() helper
function. However, rpcif_reg_{read,write}() does not take the bus size
into account, and does not double all Manual Mode Data Register access
sizes when communicating with a HyperFlash or Octal-SPI Flash device.
Fix this, and avoid the back-and-forth conversion between transfer size
and Transfer Data Enable bits, by explicitly storing the transfer size
in struct rpcif, and using that value to determine access size in
rpcif_reg_{read,write}().
Enforce that the "high" Manual Mode Read/Write Data Registers
(SM[RW]DR1) are only used for 8-byte data accesses.
While at it, forbid writing to the Manual Mode Read Data Registers,
as they are read-only.

It's noted that dcvs interrupts are not self-clearing, thus an interrupt
handler runs constantly, which leads to a severe regression in runtime.
To fix the problem an explicit write to clear interrupt register is
required, note that on OSM platforms the register may not be present.

On QCOM platforms with EPSS flavour of cpufreq IP a throttled frequency is
obtained from another register REG_DOMAIN_STATE, thus the helper function
qcom_lmh_get_throttle_freq() should be modified accordingly, as for now
it returns gibberish since .reg_current_vote is unset for EPSS hardware.
To exclude a hardcoded magic number 19200 it is replaced by "xo" clock rate

commit 398867f59f956985f4c324f173eff7b946e14bd8 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.4.6.1 states that each command frame shall
be made up from type, length and value. Looking for example in chapter
5.4.6.3.5 at the description for the encoding of a flow control on command
it becomes obvious, that the type and length field is always present
whereas the value may be zero bytes long. The current implementation omits
the length field if the value is not present. This is wrong.
Correct this by always sending the length in gsm_control_transmit().
So far only the modem status command (MSC) has included a value and encoded
its length directly. Therefore, also change gsmtty_modem_update().

commit 284260f278b706364fb4c88a7b56ba5298d5973c upstream.
Internally, we manage the alive state of the mux channels and mux itself
with the field member 'dead'. This makes it possible to notify the user
if the accessed underlying link is already gone. On the other hand,
however, removing the virtual ttys before terminating the channels may
result in peer messages being received without any internal target. Move

From: Daniel Starke <[email protected]>
commit f4f7d63287217ba25e5c80f5faae5e4f7118790e upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.4.8.1 states that XON/XOFF characters
shall be used instead of Fcon/Fcoff command in advanced option mode to
handle flow control. Chapter 5.4.8.2 describes how XON/XOFF characters
shall be handled. Basic option mode only used Fcon/Fcoff commands and no
XON/XOFF characters. These are treated as data bytes here.
The current implementation uses the gsm_mux field 'constipated' to handle
flow control from the remote peer and the gsm_dlci field 'constipated' to
handle flow control from each DLCI. The later is unrelated to this patch.
The gsm_mux field is correctly set for Fcon/Fcoff commands in
gsm_control_message(). However, the same is not true for XON/XOFF
characters in gsm1_receive().
Disable software flow control handling in the tty to allow explicit
handling by n_gsm.
Add the missing handling in advanced option mode for gsm_mux in
gsm1_receive() to comply with the standard.
This patch depends on the following commit:

commit 0543e4e8852ef5ff1809ae62f1ea963e2ab23b66 upstream.
Since commit ae8709b296d8 ("USB: core: Make do_proc_control() and
do_proc_bulk() killable") if a device has the USB_QUIRK_DELAY_CTRL_MSG
quirk set, it will temporarily block all other URBs (e.g. interrupts)
while sleeping due to a control.
This results in noticeable delays when, for example, a userspace usbfs
application is sending URB interrupts at a high rate to a keyboard and
simultaneously updates the lock indicators using controls. Interrupts
with direction set to IN are also affected by this, meaning that
delivery of HID reports (containing scancodes) to the usbfs application
is delayed as well.
This patch fixes the regression by calling msleep() while the device
mutex is unlocked, as was the case originally with usb_control_msg().

And if we fail later in phy_g12a_usb3_pcie_probe() then we
bail out w/o calling clk_disable_unprepare().

commit 50ff57888d0b13440e7f4cde05dc339ee8d0f1f8 upstream.
On a zoned filesystem, if we fail to allocate the root node for the log
root tree while syncing the log, we end up returning without finishing
the IO plug we started before, resulting in leaking resources as we
have started writeback for extent buffers of a log tree before. That
allocation failure, which typically is either -ENOMEM or -ENOSPC, is not
fatal and the fsync can safely fallback to a full transaction commit.
So release the IO plug if we fail to allocate the extent buffer for the
root of the log root tree when syncing the log on a zoned filesystem.

commit 317f86af7f5d19f286ed2d181cbaef4a188c7f19 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. The value of the modem status command (MSC) frame
contains an address field, control signal and optional break signal octet.
The address field is encoded as described in chapter 5.2.1.2 with only one
octet (may be extended to more in future versions of the standard). Whereas
the control signal and break signal octet are always one byte each. This is
strange at first glance as it makes the EA bit redundant. However, the same
two octets are also encoded as header in convergence layer type 2 as
described in chapter 5.5.2. No header length field is given and the only
way to test if there is an optional break signal octet is via the EA flag
which extends the control signal octet with a break signal octet. Now it
becomes obvious how the EA bit for those two octets shall be encoded in the
MSC frame. The current implementation treats the signal octet different for
MSC frame and convergence layer type 2 header even though the standard
describes it for both in the same way.
Use the EA bit to encode the signal octets not only in the convergence
layer type 2 header but also in the MSC frame in the same way with either
1 or 2 bytes in case of an optional break signal. Adjust the receiving path
accordingly in gsm_control_modem().

xmit_check_hhlen() observes the dst for getting the device hard header
length to make sure a modified packet can fit. When a helper which changes
the dst - such as bpf_skb_set_tunnel_key() - is called as part of the
xmit program the accessed dst is no longer valid.
This leads to the following splat:

commit e4d8a29997731b3bb14059024b24df9f784288d0 upstream.
If we pass too short string to "hex2bin" (and the string size without
the terminating NUL character is even), "hex2bin" reads one byte after
the terminating NUL character. This patch fixes it.
Note that hex_to_bin returns -1 on error and hex2bin return -EINVAL on
error - so we can't just return the variable "hi" or "lo" on error.
This inconsistency may be fixed in the next merge window, but for the
purpose of fixing this bug, we just preserve the existing behavior and
return -1 and -EINVAL.

commit 838425f2defe5262906b698752d28fd2fca1aac2 upstream.
The symbol fixup is necessary for symbols in kallsyms since they don't
have size info. So we use the next symbol's address to calculate the
size. Now it's also used for user binaries because sometimes they miss
size for hand-written asm functions.
There's a arch-specific function to handle kallsyms differently but
currently it cannot distinguish kallsyms from others. Pass this
information explicitly to handle it properly. Note that those arch
functions will be moved to the generic function so I didn't added it to
the arch-functions.

[ Upstream commit 05d8af449d93e04547b4c6b328e39c890bc803f4 ]
The current EOI handler for LEVEL triggered interrupts calls clk_enable(),
register IO, clk_disable(). The clock manipulation requires locking which
happens with IRQs disabled in clk_enable_lock(). Instead of turning the
clock on and off all the time, enable the clock in case LEVEL interrupt is
requested and keep the clock enabled until all LEVEL interrupts are freed.
The LEVEL interrupts are an exception on this platform and seldom used, so
this does not affect the common case.
This simplifies the LEVEL interrupt handling considerably and also fixes
the following splat found when using preempt-rt:

commit 6e6eebdf5e2455f089ccd000754a0deaeb79af82 upstream.
Sticky MCR bits are lost in console restoration if console suspending
has been disabled. This currently affects the AFE bit, which works in
combination with RTS which we set, so we want to make sure the UART
retains control of its FIFO where previously requested. Also specific
drivers may need other bits in the future.

The "read_bhrb" global symbol is only called under CONFIG_PPC64 of
arch/powerpc/perf/core-book3s.c but it is compiled for both 32 and 64 bit
anyway (and LLVM fails to link this on 32bit).
This fixes it by moving bhrb.o to obj64 targets.

[ Upstream commit dc3ae06c5f2170d879ff58696f629d8c3868aec3 ]
commit b4bdc4fbf8d0 ("soc: sunxi: Deal with the MBUS DMA offsets in a
central place") added a platform device notifier that sets the DMA
offset for all of the display engine frontend and backend devices.
The code applying the offset to DMA buffer physical addresses was then
removed from the backend driver in commit 756668ba682e ("drm/sun4i:
backend: Remove the MBUS quirks"), but the code subtracting PHYS_OFFSET
was left in the frontend driver.
As a result, the offset was applied twice in the frontend driver. This
likely went unnoticed because it only affects specific configurations
(scaling or certain pixel formats) where the frontend is used, on boards
with both one of these older SoCs and more than 1 GB of DRAM.
In addition, the references to PHYS_OFFSET prevent compiling the driver
on architectures where PHYS_OFFSET is not defined.

2.35.1
From: Damien Le Moal <[email protected]>
commit 1da18a296f5ba4f99429e62a7cf4fdbefa598902 upstream.
The mount option "explicit_open" manages the device open zone
resources to ensure that if an application opens a sequential file for
writing, the file zone can always be written by explicitly opening
the zone and accounting for that state with the s_open_zones counter.
However, if some zones are already open when mounting, the device open
zone resource usage status will be larger than the initial s_open_zones
value of 0. Ensure that this inconsistency does not happen by closing
any sequential zone that is open when mounting.
Furthermore, with ZNS drives, closing an explicitly open zone that has
not been written will change the zone state to "closed", that is, the
zone will remain in an active state. Since this can then cause failures
of explicit open operations on other zones if the drive active zone
resources are exceeded, we need to make sure that the zone is not
active anymore by resetting it instead of closing it. To address this,
zonefs_zone_mgmt() is modified to change a REQ_OP_ZONE_CLOSE request
into a REQ_OP_ZONE_RESET for sequential zones that have not been
written.

From: Peter Zijlstra <[email protected]>
commit 4abff6d48dbcea8200c7ea35ba70c242d128ebf3 upstream.
Occasionally objtool driven code patching (think .static_call_sites
.retpoline_sites etc..) goes sideways and it tries to patch an
instruction that doesn't match.
Much head-scatching and cursing later the problem is as outlined below
and affects every section that objtool generates for us, very much
including the ORC data. The below uses .static_call_sites because it's
convenient for demonstration purposes, but as mentioned the ORC
sections, .retpoline_sites and __mount_loc are all similarly affected.
Consider:
foo-weak.c:
extern void __SCT__foo(void);
__attribute__((weak)) void foo(void)
{
return __SCT__foo();
}
foo.c:
extern void __SCT__foo(void);
extern void my_foo(void);
void foo(void)
{
my_foo();
return __SCT__foo();
}
These generate the obvious code
(gcc -O2 -fcf-protection=none -fno-asynchronous-unwind-tables -c foo*.c):
foo-weak.o:
0000000000000000 <foo>:
0: e9 00 00 00 00 jmpq 5 <foo+0x5> 1: R_X86_64_PLT32 __SCT__foo-0x4
foo.o:
0000000000000000 <foo>:
0: 48 83 ec 08 sub $0x8,%rsp
4: e8 00 00 00 00 callq 9 <foo+0x9> 5: R_X86_64_PLT32 my_foo-0x4
9: 48 83 c4 08 add $0x8,%rsp
d: e9 00 00 00 00 jmpq 12 <foo+0x12> e: R_X86_64_PLT32 __SCT__foo-0x4
Now, when we link these two files together, you get something like
(ld -r -o foos.o foo-weak.o foo.o):
foos.o:
0000000000000000 <foo-0x10>:
0: e9 00 00 00 00 jmpq 5 <foo-0xb> 1: R_X86_64_PLT32 __SCT__foo-0x4
5: 66 2e 0f 1f 84 00 00 00 00 00 nopw %cs:0x0(%rax,%rax,1)
f: 90 nop
0000000000000010 <foo>:
10: 48 83 ec 08 sub $0x8,%rsp
14: e8 00 00 00 00 callq 19 <foo+0x9> 15: R_X86_64_PLT32 my_foo-0x4
19: 48 83 c4 08 add $0x8,%rsp
1d: e9 00 00 00 00 jmpq 22 <foo+0x12> 1e: R_X86_64_PLT32 __SCT__foo-0x4
Noting that ld preserves the weak function text, but strips the symbol
off of it (hence objdump doing that funny negative offset thing). This
does lead to 'interesting' unused code issues with objtool when ran on
linked objects, but that seems to be working (fingers crossed).
So far so good.. Now lets consider the objtool static_call output
section (readelf output, old binutils):
foo-weak.o:
Relocation section '.rela.static_call_sites' at offset 0x2c8 contains 1 entry:

So we have two patch sites, one in the dead code of the weak foo and one
in the real foo. All is well.
*HOWEVER*, when the toolchain strips unused section symbols it
generates things like this (using new enough binutils):
foo-weak.o:

0000000000000000 0000000100000002 R_X86_64_PC32 0000000000000000 foo + 0
0000000000000004 0000000d00000002 R_X86_64_PC32 0000000000000000 __SCT__foo + 1
0000000000000008 0000000100000002 R_X86_64_PC32 0000000000000000 foo + d

And now we can see how that foos.o .static_call_sites goes side-ways, we
now have _two_ patch sites in foo. One for the weak symbol at foo+0
(which is no longer a static_call site!) and one at foo+d which is in
fact the right location.
This seems to happen when objtool cannot find a section symbol, in which
case it falls back to any other symbol to key off of, however in this
case that goes terribly wrong!
As such, teach objtool to create a section symbol when there isn't
one.

From: Maciej W. Rozycki <[email protected]>
commit 637674fa40059cddcc3ad2212728965072f62ea3 upstream.
The EndRun PTP/1588 dual serial port device is based on the Oxford
Semiconductor OXPCIe952 UART device with the PCI vendor:device ID set
for EndRun Technologies and is therefore driven by a fixed 62.5MHz clock
input derived from the 100MHz PCI Express clock. The clock rate is
divided by the oversampling rate of 16 as it is supplied to the baud
rate generator, yielding the baud base of 3906250.
Replace the incorrect baud base of 4000000 with the right value of
3906250 then, complementing commit 6cbe45d8ac93 ("serial: 8250: Correct
the clock for OxSemi PCIe devices").

From: Peilin Ye <[email protected]>
[ Upstream commit 31c417c948d7f6909cb63f0ac3298f3c38f8ce20 ]
As pointed out by Jakub Kicinski, currently using TUNNEL_SEQ in
collect_md mode is racy for [IP6]GRE[TAP] devices. Consider the
following sequence of events:
1. An [IP6]GRE[TAP] device is created in collect_md mode using "ip link
add ... external". "ip" ignores "[o]seq" if "external" is specified,
so TUNNEL_SEQ is off, and the device is marked as NETIF_F_LLTX (i.e.
it uses lockless TX);
2. Someone sets TUNNEL_SEQ on outgoing skb's, using e.g.
bpf_skb_set_tunnel_key() in an eBPF program attached to this device;
3. gre_fb_xmit() or __gre6_xmit() processes these skb's:
gre_build_header(skb, tun_hlen,
flags, protocol,
tunnel_id_to_key32(tun_info->key.tun_id),
(flags & TUNNEL_SEQ) ? htonl(tunnel->o_seqno++)
: 0); ^^^^^^^^^^^^^^^^^
Since we are not using the TX lock (&txq->_xmit_lock), multiple CPUs may
try to do this tunnel->o_seqno++ in parallel, which is racy. Fix it by
making o_seqno atomic_t.
As mentioned by Eric Dumazet in commit b790e01aee74 ("ip_gre: lockless
xmit"), making o_seqno atomic_t increases "chance for packets being out
of order at receiver" when NETIF_F_LLTX is on.
Maybe a better fix would be:
1. Do not ignore "oseq" in external mode. Users MUST specify "oseq" if
they want the kernel to allow sequencing of outgoing packets;
2. Reject all outgoing TUNNEL_SEQ packets if the device was not created
with "oseq".
Unfortunately, that would break userspace.
We could now make [IP6]GRE[TAP] devices always NETIF_F_LLTX, but let us
do it in separate patches to keep this fix minimal.

This reverts commit bfe55a1f7fd6bfede16078bf04c6250fbca11588.
This was presumably misdiagnosed as an inability to use C3 at
all when I suspect the real problem is just misconfiguration of
C3 vs. ARB_DIS.

commit c7428dbddcf4ea1919e1c8e15f715b94ca359268 upstream.
If the user sets the usb_request's no_interrupt, then there will be no
completion event for the request. Currently the driver incorrectly uses
the event status of a different request to report the status for a
request with no_interrupt. The dwc3 driver needs to check the TRB status
associated with the request when reporting its status.
Note: this is only applicable to missed_isoc TRB completion status, but
the other status are also listed for completeness/documentation.

Make sure that the clock is unprepared on exit by changing clk_disable
to clk_disable_unprepare.

commit 8ec1442953c66a1d8462cccd8c20b7ba561f5915 upstream.
These patch_text implementations are using stop_machine_cpuslocked
infrastructure with atomic cpu_count. The original idea: When the
master CPU patch_text, the others should wait for it. But current
implementation is using the first CPU as master, which couldn't
guarantee the remaining CPUs are waiting. This patch changes the
last CPU as the master to solve the potential risk.

From: Alexey Kardashevskiy <[email protected]>
commit d799769188529abc6cbf035a10087a51f7832b6b upstream.
When ld detects unaligned relocations, it emits R_PPC64_UADDR64
relocations instead of R_PPC64_RELATIVE. Currently R_PPC64_UADDR64 are
detected by arch/powerpc/tools/relocs_check.sh and expected not to work.
Below is a simple chunk to trigger this behaviour (this disables
optimization for the demonstration purposes only, this also happens with
-O1/-O2 when CONFIG_PRINTK_INDEX=y, for example):
\#pragma GCC push_options
\#pragma GCC optimize ("O0")
struct entry {
const char *file;
int line;
} __attribute__((packed));
static const struct entry e1 = { .file = __FILE__, .line = __LINE__ };
static const struct entry e2 = { .file = __FILE__, .line = __LINE__ };
...
prom_printf("e1=%s %lx %lx\n", e1.file, (unsigned long) e1.file, mfmsr());
prom_printf("e2=%s %lx\n", e2.file, (unsigned long) e2.file);
\#pragma GCC pop_options
This adds support for UADDR64 for 64bit. This reuses __dynamic_symtab
from the 32bit code which supports more relocation types already.
Because RELACOUNT includes only R_PPC64_RELATIVE, this replaces it with
RELASZ which is the size of all relocation records.

pm_runtime_get_sync will increment pm usage counter
even it failed. Forgetting to putting operation will
result in reference leak here. We fix it by replacing
it with pm_runtime_resume_and_get to keep usage counter

stream reconf request arrives after the timer is triggered, such as:
send Incoming SSN Reset Request --->
CPU0:
reconf timer is triggered,

continue the handler code, hold sk lock,
and try to hold asoc->strreset_chunk, crash!

EEH calls into bnx2x twice based on the system log above, first through
bnx2x_io_error_detected() and then bnx2x_io_slot_reset(), and executes
the following call chains:

+-> __netif_napi_del()
bnx2x_io_slot_reset()
+-> bnx2x_netif_stop()
+-> bnx2x_napi_disable()
+->napi_disable()
Fix this by correcting the sequence of NAPI APIs usage,
that is delete the NAPI after disabling it.

[ Upstream commit a12315d6d27093392b6c634e1d35a59f1d1f7a59 ]
On beagleboard revisions A to B4 we need to use gpt12 as the system timer.
However, the quirk handling added for gpt12 caused a regression for system
suspend for am335x as the PM coprocessor needs the timers idled for
suspend.
Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need
it. Beagleboard revisions C and later no longer need to use the gpt12
related quirk. Then at some point, if we decide to drop support for the old
beagleboard revisions A to B4, we can also drop the gpt12 related quirks
completely.

commit acb16b395c3f3d7502443e0c799c2b42df645642 upstream.
We received a report[1] of kernel crashes when Cilium is used in XDP
mode with virtio_net after updating to newer kernels. After
investigating the reason it turned out that when using mergeable bufs
with an XDP program which adjusts xdp.data or xdp.data_meta page_to_buf()
calculates the build_skb address wrong because the offset can become less
than the headroom so it gets the address of the previous page (-X bytes
depending on how lower offset is):
page_to_skb: page addr ffff9eb2923e2000 buf ffff9eb2923e1ffc offset 252 headroom 256
This is a pr_err() I added in the beginning of page_to_skb which clearly
shows offset that is less than headroom by adding 4 bytes of metadata
via an xdp prog. The calculations done are:
receive_mergeable():
headroom = VIRTIO_XDP_HEADROOM; // VIRTIO_XDP_HEADROOM == 256 bytes
offset = xdp.data - page_address(xdp_page) -
vi->hdr_len - metasize;
page_to_skb():
p = page_address(page) + offset;
...
buf = p - headroom;
Now buf goes -4 bytes from the page's starting address as can be seen
above which is set as skb->head and skb->data by build_skb later. Depending
on what's done with the skb (when it's freed most often) we get all kinds
of corruptions and BUG_ON() triggers in mm[2]. We have to recalculate
the new headroom after the xdp program has run, similar to how offset
and len are recalculated. Headroom is directly related to
data_hard_start, data and data_meta, so we use them to get the new size.
The result is correct (similar pr_err() in page_to_skb, one case of
xdp_page and one case of virtnet buf):
a) Case with 4 bytes of metadata
[ 115.949641] page_to_skb: page addr ffff8b4dcfad2000 offset 252 headroom 252
[ 121.084105] page_to_skb: page addr ffff8b4dcf018000 offset 20732 headroom 252
b) Case of pushing data +32 bytes
[ 153.181401] page_to_skb: page addr ffff8b4dd0c4d000 offset 288 headroom 288
[ 158.480421] page_to_skb: page addr ffff8b4dd00b0000 offset 24864 headroom 288
c) Case of pushing data -33 bytes
[ 835.906830] page_to_skb: page addr ffff8b4dd3270000 offset 223 headroom 223
[ 840.839910] page_to_skb: page addr ffff8b4dcdd68000 offset 12511 headroom 223
Offset and headroom are equal because offset points to the start of
reserved bytes for the virtio_net header which are at buf start +
headroom, while data points at buf start + vnet hdr size + headroom so
when data or data_meta are adjusted by the xdp prog both the headroom size
and the offset change equally. We can use data_hard_start to compute the
new headroom after the xdp prog (linearized / page start case, the
virtnet buf case is similar just with bigger base offset):
xdp.data_hard_start = page_address + vnet_hdr
xdp.data = page_address + vnet_hdr + headroom
new headroom after xdp prog = xdp.data - xdp.data_hard_start - metasize
An example reproducer xdp prog[3] is below.

[ Upstream commit fa51e1dc4b91375bc18349663a52395ad585bd3c ]
On a custom carrier board with a i.MX6Q Apalis SoM, the sgtl5000 codec
on the SoM is often not detected and the following error message is
seen when the sgtl5000 driver tries to read the ID register:
sgtl5000 1-000a: Error reading chip id -6
The reason for the error is that the MCLK clock is not provided
early enough.
Fix the problem by describing the MCLK pinctrl inside the codec
node instead of placing it inside the audmux pinctrl group.
With this change applied the sgtl5000 is always detected on every boot.

[ 16.359638] fsl_spi b01004c0.spi: unable to map tx dma
This is due to the AT25 driver using buffers on stack, which is not
possible with CONFIG_VMAP_STACK.
As mentionned in kernel Documentation (Documentation/spi/spi-summary.rst):
- Follow standard kernel rules, and provide DMA-safe buffers in
your messages. That way controller drivers using DMA aren't forced
to make extra copies unless the hardware requires it (e.g. working
around hardware errata that force the use of bounce buffering).
Modify the driver to use a buffer located in the at25 device structure
which is allocated via kmalloc during probe.
Protect writes in this new buffer with the driver's mutex.

[ Upstream commit dd2737fab4a6ce9ba4eb84842bedbd87d55241a6 ]
The fsl,scu.txt dt-binding documentation explicitly mentions
that the compatible string should be either "fsl,imx8qm-clock"
or "fsl,imx8qxp-clock", followed by "fsl,scu-clk". Also, i.MX8qm
SCU clocks and i.MX8qxp SCU clocks are really not the same, so
we have to set the compatible property according to SoC name.
Let's correct the i.MX8qm clock controller's compatible property
from
"fsl,imx8qxp-clk", "fsl,scu-clk"
to
"fsl,imx8qm-clk", "fsl,scu-clk" .

[ Upstream commit 48009e9972974c52a5f649f761862dd67bce3d13 ]
Currently, function hclge_get_ring_chain_from_mbx will return -ENOMEM if
ring_num is bigger than HCLGE_MBX_MAX_RING_CHAIN_PARAM_NUM. It is better to
return -EINVAL for the invalid parameter case.
So this patch fixes it by return -EINVAL in this abnormal branch.

commit dc92944a014cd6a6f6c94299aaa36164dd2c238a upstream.
While rebooting, XHCI controller and its bus device will be shut down
in order by .shutdown callback. Stopping roothubs polling in
xhci_shutdown() can prevent XHCI driver from accessing port status
after its bus device shutdown.
Take PCIe XHCI controller as example, if XHCI driver doesn't stop roothubs
polling, XHCI driver may access PCIe BAR register for port status after
parent PCIe root port driver is shutdown and cause PCIe bus error.

[ Upstream commit 9c85a9bae267f6b5e5e374d0d023bbbe9db096d3 ]
Avoid calling mmap with requested addresses that are less than the
system's mmap_min_addr. When run as root, mmap returns EACCES when
trying to map addresses < mmap_min_addr. This is not one of the error
codes for the condition to retry the mmap in the test.
Rather than arbitrarily retrying on EACCES, don't attempt an mmap until
addr > vm.mmap_min_addr.
Add a munmap call after an alignment check as the mappings are retained
after the retry and can reach the vm.max_map_count sysctl.

[ Upstream commit 18d609daa546c919fd36b62a7b510c18de4b4af8 ]
Because mremap does not have a MAP_FIXED_NOREPLACE flag, it can destroy
existing mappings. This causes a segfault when regions such as text are
remapped and the permissions are changed.
Verify the requested mremap destination address does not overlap any
existing mappings by using mmap's MAP_FIXED_NOREPLACE flag. Keep
incrementing the destination address until a valid mapping is found or
fail the current test once the max address is reached.

From: Ville Syrjälä <[email protected]>
commit fc45e55ebc58dbf622cb89ddbf797589c7a5510b upstream.
The "safe state" index is used by acpi_idle_enter_bm() to avoid
entering a C-state that may require bus mastering to be disabled
on entry in the cases when this is not going to happen. For this
reason, it should not be set to point to C3 type of C-states, because
they may require bus mastering to be disabled on entry in principle.
This was broken by commit d6b88ce2eb9d ("ACPI: processor idle: Allow
playing dead in C3 state") which inadvertently allowed the "safe
state" index to point to C3 type of C-states.
This results in a machine that won't boot past the point when it first
enters C3. Restore the correct behaviour (either demote to C1/C2, or
use C3 but also set ARB_DIS=1).
I hit this on a Fujitsu Siemens Lifebook S6010 (P3) machine.

[ Upstream commit 46ff3df87215ff42c0cd2c4bdb7d74540384a69c ]
The pinout of the OMAP35 and DM37 variants of the SOM-LV are the
same, but the macros which define the pinmuxing are different
between OMAP3530 and DM3730. The pinmuxing was correct for
for the DM3730, but wrong for the OMAP3530. Since the boot loader
was correctly pin-muxing the pins, this was not obvious. As the
bootloader not guaranteed to pinmux all the pins any more, this
causes an issue, so the pinmux needs to be moved from a common
file to their respective board files.

commit ba7542eb2dd5dfc75c457198b88986642e602065 upstream.
This patch fixes a memory corruption that occurred in the
nand_scan() path for Hynix nand device.
On boot, for Hynix nand device will panic at a weird place:

The problem is that the nand_scan()'s qcom_nand_attach_chip callback
is updating the nandc->max_cwperpage from 1 to 4 or 8 based on page size.
This causes the sg_init_table of clear_bam_transaction() in the driver's
qcom_nandc_command() to memset much more than what was initially
allocated by alloc_bam_transaction().
This patch will update nandc->max_cwperpage 1 to 4 or 8 based on page
size in qcom_nand_attach_chip call back after freeing the previously
allocated memory for bam txn as per nandc->max_cwperpage = 1 and then
again allocating bam txn as per nandc->max_cwperpage = 4 or 8 based on
page size in qcom_nand_attach_chip call back itself.

commit 71d471e3faf90c9674cadc7605ac719e82cb7fac upstream.
During the uvcg_video_pump() process, if an error occurs and
uvcg_queue_cancel() is called, the buffer queue will be cleared out, but
the current marker (queue->buf_used) of the active buffer (no longer
active) is not reset. On the next iteration of uvcg_video_pump() the
stale buf_used count will be used and the logic of min((unsigned
int)len, buf->bytesused - queue->buf_used) may incorrectly calculate a
nbytes size, causing an invalid memory access.

From: Mikulas Patocka <[email protected]>
commit e5be15767e7e284351853cbaba80cde8620341fb upstream.
The function hex2bin is used to load cryptographic keys into device
mapper targets dm-crypt and dm-integrity. It should take constant time
independent on the processed data, so that concurrently running
unprivileged code can't infer any information about the keys via
microarchitectural convert channels.
This patch changes the function hex_to_bin so that it contains no
branches and no memory accesses.
Note that this shouldn't cause performance degradation because the size
of the new function is the same as the size of the old function (on
x86-64) - and the new function causes no branch misprediction penalties.
I compile-tested this function with gcc on aarch64 alpha arm hppa hppa64
i386 ia64 m68k mips32 mips64 powerpc powerpc64 riscv sh4 s390x sparc32
sparc64 x86_64 and with clang on aarch64 arm hexagon i386 mips32 mips64
powerpc powerpc64 s390x sparc32 sparc64 x86_64 to verify that there are
no branches in the generated code.

commit e64d5fa5044f225ac87d96a7e4be11389999c4c6 upstream.
During hibernation process, once thaw() stage completes, the MHI endpoint
devices will be in M0 state post recovery. After that, the devices will be
powered down so that the system can enter the target sleep state. During
this stage, the PCI core will put the devices in D3hot. But this transition
is allowed by the MHI spec. The devices can only enter D3hot when it is in
M3 state.
So for fixing this issue, let's add the poweroff() callback that will get
executed before putting the system in target sleep state during
hibernation. This callback will power down the device properly so that it
could be restored during restore() or thaw() stage.

[ Upstream commit 554c577cee95bdc1d03d9f457e57dc96eb791845 ]
Currently, instead of performing a short write,
iomap_file_buffered_write will fail when part of its iov iterator cannot
be read. In contrast, gfs2_file_buffered_write will loop around if it
can read part of the iov iterator, so we can end up in an endless loop.
This should be fixed in iomap_file_buffered_write (and also
generic_perform_write), but this comes a bit late in the 5.16
development cycle, so work around it in the filesystem by
trimming the iov iterator to the known-good size for now.

[ Upstream commit b253a0680ceadc5d7b4acca7aa2d870326cad8ad ]
If an ACK (s)acks multiple skbs, we favor the information
from the most recently sent skb by choosing the skb with
the highest prior_delivered count. But in the interval
between receiving ACKs, we send multiple skbs with the same
prior_delivered, because the tp->delivered only changes
when we receive an ACK.
We used RACK's solution, copying tcp_rack_sent_after() as
tcp_skb_sent_after() helper to determine "which packet was
sent last?". Later, we will use tcp_skb_sent_after() instead
in RACK.

2.35.1
From: Daniel Starke <[email protected]>
commit aa371e96f05dcb36a88298f5cb70aa7234d5e8b8 upstream.
n_gsm is based on the 3GPP 07.010 and its newer version is the 3GPP 27.010.
See https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=1516
The changes from 07.010 to 27.010 are non-functional. Therefore, I refer to
the newer 27.010 here. Chapter 5.8.2 states that both sides will revert to
the non-multiplexed mode via a close-down message (CLD). The usual program
flow is as following:
- start multiplex mode by sending AT+CMUX to the mobile
- establish the control channel (DLCI 0)
- establish user channels (DLCI >0)
- terminate user channels
- send close-down message (CLD)
- revert to AT protocol (i.e. leave multiplexed mode)
The AT protocol is out of scope of the n_gsm driver. However,
gsm_disconnect() sends CLD if gsm_config() detects that the requested
parameters require the mux protocol to restart. The next immediate action
is to start the mux protocol by opening DLCI 0 again. Any responder side
which handles CLD commands correctly forces us to fail at this point
because AT+CMUX needs to be sent to the mobile to start the mux again.
Therefore, remove the CLD command in this phase and keep both sides in
multiplexed mode.
Remove the gsm_disconnect() function as it become unnecessary and merge the
remaining parts into gsm_cleanup_mux() to handle the termination order and
locking correctly.

commit 7e0815b3e09986d2fe651199363e135b9358132a upstream.
When a XEN_HVM guest uses the XEN PIRQ/Eventchannel mechanism, then
PCI/MSI[-X] masking is solely controlled by the hypervisor, but contrary to
XEN_PV guests this does not disable PCI/MSI[-X] masking in the PCI/MSI
layer.
This can lead to a situation where the PCI/MSI layer masks an MSI[-X]
interrupt and the hypervisor grants the write despite the fact that it
already requested the interrupt. As a consequence interrupt delivery on the
affected device is not happening ever.
Set pci_msi_ignore_mask to prevent that like it's done for XEN_PV guests
already.

[ Upstream commit a6823e4e360fe975bd3da4ab156df7c74c8b07f3 ]
The first "if" condition in __memcpy_flushcache is supposed to align the
"dest" variable to 8 bytes and copy data up to this alignment. However,
this condition may misbehave if "size" is greater than 4GiB.
The statement min_t(unsigned, size, ALIGN(dest, 8) - dest); casts both
arguments to unsigned int and selects the smaller one. However, the
cast truncates high bits in "size" and it results in misbehavior.
For example:
suppose that size == 0x100000001, dest == 0x200000002
min_t(unsigned, size, ALIGN(dest, 8) - dest) == min_t(0x1, 0xe) == 0x1;
...
dest += 0x1;
so we copy just one byte "and" dest remains unaligned.
This patch fixes the bug by replacing unsigned with size_t.

[ Upstream commit 8d2453d9a307c2eafd21242dd73f35f05fb7ce74 ]
We currently are getting the following warning after a system suspend:
Powerdomain (vpe_pwrdm) didn't enter target state 0
Looks like this is because the STANDBYMODE bit for SMART_IDLE should
not be used. The TRM "Table 12-348. VPE_SYSCONFIG" says that the value
for SMART_IDLE is "0x2: Same behavior as bit-field value of 0x1". But
if the SMART_IDLE value is used, PM_VPE_PWRSTST LASTPOWERSTATEENTERED
bits always show value of 3.
Let's fix the issue by dropping SMART_IDLE for vpe. And let's also add
the missing the powerdomain for vpe.

commit 1adf6fee58ca25fb6720b8d34c919dcf5425cc9c upstream.
gsm_control_modem() informs the virtual tty that more data can be written
after receiving a control signal octet via modem status command (MSC).
However, gsm_dlci_data() fails to do the same after receiving a control
signal octet from the convergence layer type 2 header.
Add tty_wakeup() in gsm_dlci_data() for convergence layer type 2 to fix
this.

Due to what looks like a copy-paste error, the ECSPI2_MISO pad is not
muxed for SPI mode and causes reads from a slave-device connected to the

gw73xx families of boards that got this wrong.

The commit referenced below fixed packet re-routing if Netfilter mangles
a routing key property of a packet and the packet is routed in a VRF L3
domain. The fix, however, addressed IPv4 re-routing, only.
This commit applies the same behavior for IPv6. While at it, untangle
the nested ternary operator to make the code more readable.

The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable(). And use pm_runtime_dont_use_autosuspend() to
undo pm_runtime_use_autosuspend()
In the PM Runtime docs:
Drivers in ->remove() callback should undo the runtime PM changes done
in ->probe(). Usually this means calling pm_runtime_disable(),
pm_runtime_dont_use_autosuspend() etc.
We should do this in error handling.

[ Upstream commit e91ac20889d1a26d077cc511365cd7ff4346a6f3 ]
In some situations software handles TRB events slower than adding TRBs.
If the number of TRB events to be processed in a given interrupt is exactly
the same as the event ring size 256, then the local variable
"event_ring_deq" that holds the initial dequeue position is equal to
software_dequeue after handling all 256 interrupts.
It will cause driver to not update ERDP to hardware,
Software dequeue pointer is out of sync with ERDP on interrupt exit.
On the next interrupt, the event ring may full but driver will not
update ERDP as software_dequeue is equal to ERDP.

[ Upstream commit 2fb251c265608636fc961b7d38e1a03937e57371 ]
Similar to the sc7180 commit, let's drop the IP0 interconnects here
because the IP0 resource is also used in the clk-rpmh driver on sdx55.
It's bad to have the clk framework and interconnect framework control
the same RPMh resource without any coordination. The rpmh driver in the
kernel doesn't aggregate resources between clients either, so leaving
control to clk-rpmh avoids any issues with unused interconnects turning
off IP0 behind the back of the clk framework.

When direct writes fail with -ENOTBLK because we're writing into a
hole (gfs2_iomap_begin()) or because of a page invalidation failure
(iomap_dio_rw()), we're falling back to buffered writes. In that case,
when we lose the inode glock in gfs2_file_buffered_write(), we want to
re-acquire it instead of returning a short write.

[ Upstream commit 45ac774c33d834fe9d4de06ab5f1022fe8cd2071 ]
When we try to transmit an skb with md_dst attached through wireguard
we hit a null pointer dereference in wg_xmit() due to the use of
dst_mtu() which calls into dst_blackhole_mtu() which in turn tries to
dereference dst->dev.
Since wireguard doesn't use md_dsts we should use skb_valid_dst(), which
checks for DST_METADATA flag, and if it's set, then falls back to
wireguard's device mtu. That gives us the best chance of transmitting
the packet; otherwise if the blackhole netdev is used we'd get
ETH_MIN_MTU.

The VF driver can forward any IPsec flags and such makes the function
is not extendable and prone to backward/forward incompatibility.
If new software runs on VF, it won't know that PF configured something
completely different as it "knows" only XFRM_OFFLOAD_INBOUND flag.

[ Upstream commit 296abc0d91d8b65d42224dd33452ace14491ad08 ]
Commit 00bfe02f4796 ("gfs2: Fix mmap + page fault deadlocks for buffered
I/O") changed gfs2_file_read_iter() and gfs2_file_buffered_write() to
allow dropping the inode glock while faulting in user buffers. When the
lock was dropped, a short result was returned to indicate that the
operation was interrupted.
As pointed out by Linus (see the link below), this behavior is broken
and the operations should always re-acquire the inode glock and resume
the operation instead.

2.35.1
From: Duoming Zhou <[email protected]>
[ Upstream commit eb5adc70754d26a260f8b42d39db42da0d0af500 ]
There is a deadlock in rs_close(), which is shown
below:
(Thread 1) | (Thread 2)
| rs_open()
rs_close() | mod_timer()
spin_lock_bh() //(1) | (wait a time)
... | rs_poll()
del_timer_sync() | spin_lock() //(2)
(wait timer to stop) | ...
We hold timer_lock in position (1) of thread 1 and
use del_timer_sync() to wait timer to stop, but timer handler
also need timer_lock in position (2) of thread 2.
As a result, rs_close() will block forever.
This patch deletes the redundant timer_lock in order to
prevent the deadlock. Because there is no race condition
between rs_close, rs_open and rs_poll.
