[ Upstream commit b4c639f699349880b7918b861e1bd360442ec450 ]
Jens reported a compiler warning when using
CONFIG_CC_OPTIMIZE_FOR_SIZE=y that looks like this
fs/btrfs/tree-log.c: In function ‘btrfs_log_prealloc_extents’:
fs/btrfs/tree-log.c:4828:23: warning: ‘start_slot’ may be used
uninitialized [-Wmaybe-uninitialized]
4828 | ret = copy_items(trans, inode, dst_path, path,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4829 | start_slot, ins_nr, 1, 0);
| ~~~~~~~~~~~~~~~~~~~~~~~~~
fs/btrfs/tree-log.c:4725:13: note: ‘start_slot’ was declared here
4725 | int start_slot;
| ^~~~~~~~~~
The compiler is incorrect, as we only use this code when ins_len > 0,
and when ins_len > 0 we have start_slot properly initialized. However
we generally find the -Wmaybe-uninitialized warnings valuable, so
initialize start_slot to get rid of the warning.

[ Upstream commit 1bf76df3fee56d6637718e267f7c34ed70d0c7dc ]
When running a delayed tree reference, if we find a ref count different
from 1, we return -EIO. This isn't an IO error, as it indicates either a
bug in the delayed refs code or a memory corruption, so change the error
code from -EIO to -EUCLEAN. Also tag the branch as 'unlikely' as this is
not expected to ever happen, and change the error message to print the
tree block's bytenr without the parenthesis (and there was a missing space
between the 'block' word and the opening parenthesis), for consistency as
that's the style we used everywhere else.

[ Upstream commit 5ad37b5e30433afa7a5513e3eb61f69fa0976785 ]
On mapphone devices we may get lots of noise on the micro-USB port in debug
uart mode until the phy-cpcap-usb driver probes. Let's limit the noise by
using overrun-throttle-ms.
Note that there is also a related separate issue where the charger cable
connected may cause random sysrq requests until phy-cpcap-usb probes that
still remains.

[ Upstream commit c1ed72171ed580fbf159e703b77685aa4b0d0df5 ]
Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CBA
has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
the kernel overrides it to EdgeHigh.
This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

[ Upstream commit 892a012699fc0b91a2ed6309078936191447f480 ]
After the commit 0ec4e55e9f57 ("ACPI: resources: Add checks for ACPI
IRQ override") is reverted, the keyboard on Medion laptops can't
work again.
To fix the keyboard issue, add a DMI-based override check that will
not affect other machines along the lines of prt_quirks[] in
drivers/acpi/pci_irq.c.
If similar issues are seen on other platforms, the quirk table could
be expanded in the future.

commit 1d30162f35c7a73fc2f8cdcdcdbd690bedb99d1a upstream.
Device flags are displayed incorrectly:
1) The comparison (i == F_FLOW_SEQ) is always false, because F_FLOW_SEQ
is equal to (1 << FLOW_SEQ_SHIFT) == 2048, and the maximum value
of the 'i' variable is (NR_PKT_FLAG - 1) == 17. It should be compared
with FLOW_SEQ_SHIFT.
2) Similarly to the F_IPSEC flag.
3) Also add spaces to the print end of the string literal "spi:%u"
to prevent the output from merging with the flag that follows.

This allows to remove an expired element which is not possible in other
existing set backends, this is more noticeable if gc-interval is high so
expired elements remain in the tree. On-demand gc also does not help in
this case, because this is delete element path. Return NULL if element
has expired.

Indeed, the variable pin6 is declared and initialized unconditionally,
while it is only used and needlessly re-initialized when support for
IPv6 is enabled.
Fix this by dropping the unused variable initialization, and moving the
variable declaration inside the existing section protected by a check
for CONFIG_IPV6.

commit a13b67c9a015c4e21601ef9aa4ec9c5d972df1b4 upstream.
Christian Theune says:
I upgraded from 6.1.38 to 6.1.55 this morning and it broke my traffic shaping script,
leaving me with a non-functional uplink on a remote router.
A 'rt' curve cannot be used as a inner curve (parent class), but we were
allowing such configurations since the qdisc was introduced. Such
configurations would trigger a UAF as Budimir explains:
The parent will have vttree_insert() called on it in init_vf(),
but will not have vttree_remove() called on it in update_vf()
because it does not have the HFSC_FSC flag set.
The qdisc always assumes that inner classes have the HFSC_FSC flag set.
This is by design as it doesn't make sense 'qdisc wise' for an 'rt'
curve to be an inner curve.
Budimir's original patch disallows users to add classes with a 'rt'
parent, but this is too strict as it breaks users that have been using
'rt' as a inner class. Another approach, taken by this patch, is to
upgrade the inner 'rt' into a 'sc', warning the user in the process.
It avoids the UAF reported by Budimir while also being more permissive
to bad scripts/users/code using 'rt' as a inner class.
Users checking the `tc class ls [...]` or `tc class get [...]` dumps would
observe the curve change and are potentially breaking with this change.

commit fc6f716a5069180c40a8c9b63631e97da34f64a3 upstream.
The hardware provides the indexes of the first and the last available
queue and VF. From the indexes, the driver calculates the numbers of
queues and VFs. In theory, a faulty device might say the last index is
smaller than the first index. In that case, the driver's calculation
would underflow, it would attempt to write to non-existent registers
outside of the ioremapped range and crash.
I ran into this not by having a faulty device, but by an operator error.
I accidentally ran a QE test meant for i40e devices on an ice device.
The test used 'echo i40e > /sys/...ice PCI device.../driver_override',
bound the driver to the device and crashed in one of the wr32 calls in
i40e_clear_hw.
Add checks to prevent underflows in the calculations of num_queues and
num_vfs. With this fix, the wrong device probing reports errors and
returns a failure without crashing.

commit f921a4a5bffa8a0005b190fb9421a7fc1fd716b6 upstream.
In commit 75eefc6c59fd ("tcp: tsq: add a shortcut in tcp_small_queue_check()")
we allowed to send an skb regardless of TSQ limits being hit if rtx queue
was empty or had a single skb, in order to better fill the pipe
when/if TX completions were slow.
Then later, commit 75c119afe14f ("tcp: implement rb-tree based
retransmit queue") accidentally removed the special case for
one skb in rtx queue.
Stefan Wahren reported a regression in single TCP flow throughput
using a 100Mbit fec link, starting from commit 65466904b015 ("tcp: adjust
TSO packet sizes based on min_rtt"). This last commit only made the
regression more visible, because it locked the TCP flow on a particular
behavior where TSQ prevented two skbs being pushed downstream,
adding silences on the wire between each TSO packet.
Many thanks to Stefan for his invaluable help !

commit 1c2709cfff1dedbb9591e989e2f001484208d914 upstream.
We discovered from packet traces of slow loss recovery on kernels with
the default HZ=250 setting (and min_rtt < 1ms) that after reordering,
when receiving a SACKed sequence range, the RACK reordering timer was
firing after about 16ms rather than the desired value of roughly
min_rtt/4 + 2ms. The problem is largely due to the RACK reorder timer
calculation adding in TCP_TIMEOUT_MIN, which is 2 jiffies. On kernels
with HZ=250, this is 2*4ms = 8ms. The TLP timer calculation has the
exact same issue.
This commit fixes the TLP transmit timer and RACK reordering timer
floor calculation to more closely match the intended 2ms floor even on
kernels with HZ=250. It does this by adding in a new
TCP_TIMEOUT_MIN_US floor of 2000 us and then converting to jiffies,
instead of the current approach of converting to jiffies and then
adding th TCP_TIMEOUT_MIN value of 2 jiffies.
Our testing has verified that on kernels with HZ=1000, as expected,
this does not produce significant changes in behavior, but on kernels
with the default HZ=250 the latency improvement can be large. For
example, our tests show that for HZ=250 kernels at low RTTs this fix
roughly halves the latency for the RACK reorder timer: instead of
mostly firing at 16ms it mostly fires at 8ms.

commit b2f750c3a80b285cd60c9346f8c96bd0a2a66cde upstream.
When either reset- or shutdown-gpio have are initially deasserted,
e.g. after a reboot - or when the hardware does not include pull-down,
there will be a short toggle of both IOs to logical 0 and back to 1.
It seems that the rfkill default is unblocked, so the driver should not
glitch to output low during probe.
It can lead e.g. to unexpected lte modem reconnect:
[1] root@localhost:~# dmesg | grep "usb 2-1"
[ 2.136124] usb 2-1: new SuperSpeed USB device number 2 using xhci-hcd
[ 21.215278] usb 2-1: USB disconnect, device number 2
[ 28.833977] usb 2-1: new SuperSpeed USB device number 3 using xhci-hcd
The glitch has been discovered on an arm64 board, now that device-tree
support for the rfkill-gpio driver has finally appeared :).
Change the flags for devm_gpiod_get_optional from GPIOD_OUT_LOW to
GPIOD_ASIS to avoid any glitches.
The rfkill driver will set the intended value during rfkill_sync_work.

commit 3e4bc23926b83c3c67e5f61ae8571602754131a6 upstream.
xfrm_gen_index() mutual exclusion uses net->xfrm.xfrm_policy_lock.
This means we must use a per-netns idx_generator variable,
instead of a static one.
Alternative would be to use an atomic variable.

commit 2f3389c73832ad90b63208c0fc281ad080114c7a upstream.
Driver allocates the LL2 rx buffers from kmalloc()
area to construct the skb using slab_build_skb()
The required size allocation seems to have overlooked
for accounting both skb_shared_info size and device
placement padding bytes which results into the below
panic when doing skb_put() for a standard MTU sized frame.

commit d351c1ea2de3e36e608fc355d8ae7d0cc80e6cd6 upstream.
mcast packets get looped back to the local machine.
Such packets have a 0-length mac header, we should treat
this like "mac header not set" and abort rule evaluation.
As-is, we just copy data from the network header instead.

commit a16eb25b09c02a54c1c1b449d4b6cfa2cf3f013a upstream.
Per the SDM, "When the local APIC handles a performance-monitoring
counters interrupt, it automatically sets the mask flag in the LVT
performance counter register." Add this behavior to KVM's local APIC
emulation.
Failure to mask the LVTPC entry results in spurious PMIs, e.g. when
running Linux as a guest, PMI handlers that do a "late_ack" spew a large
number of "dazed and confused" spurious NMI warnings.

commit 242e34500a32631f85c2b4eb6cb42a368a39e54f upstream.
Since the introduction of the ice driver the code has been
double-shifting the RSS enabling field, because the define already has
shifts in it and can't have the regular pattern of "a << shiftval &
mask" applied.
Most places in the code got it right, but one line was still wrong. Fix
this one location for easy backports to stable. An in-progress patch
fixes the defines to "standard" and will be applied as part of the
regular -next process sometime after this one.

commit 9d1a3c74746428102d55371fbf74b484733937d9 upstream.
bacmp() is a wrapper around memcpy(), which contain compile-time
checks for buffer overflow. Since the hci_conn_request_evt() also calls
bt_dev_dbg() with an implicit NULL pointer check, the compiler is now
aware of a case where 'hdev' is NULL and treats this as meaning that
zero bytes are available:
In file included from net/bluetooth/hci_event.c:32:
In function 'bacmp',
inlined from 'hci_conn_request_evt' at net/bluetooth/hci_event.c:3276:7:
include/net/bluetooth/bluetooth.h:364:16: error: 'memcmp' specified bound 6 exceeds source size 0 [-Werror=stringop-overread]
364 | return memcmp(ba1, ba2, sizeof(bdaddr_t));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Add another NULL pointer check before the bacmp() to ensure the compiler
understands the code flow enough to not warn about it. Since the patch
that introduced the warning is marked for stable backports, this one
should also go that way to avoid introducing build regressions.

commit 92d4abd66f7080075793970fc8f241239e58a9e7 upstream.
When the vhci device is opened in the two-step way, i.e.: open device
then write a vendor packet with requested controller type, the device
shall respond with a vendor packet which includes HCI index of created
interface.
When the virtual HCI is created, the host sends a reset request to the
controller. This request is processed by the vhci_send_frame() function.
However, this request is send by a different thread, so it might happen
that this HCI request will be received before the vendor response is
queued in the read queue. This results in the HCI vendor response and
HCI reset request inversion in the read queue which leads to improper
behavior of btvirt:
> dmesg

[1754265.043775] Bluetooth: hci1: Opcode 0x c03 failed: -110
In order to synchronize vhci two-step open/setup process with virtual
HCI initialization, this patch adds internal lock when queuing data in
the vhci_send_frame() function.

commit 1ffc6f8cc33268731fcf9629fc4438f6db1191fc upstream.
This change is used to relieve CVE-2020-26555. The description of
the CVE:
Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification
1.0B through 5.2 may permit an unauthenticated nearby device to spoof
the BD_ADDR of the peer device to complete pairing without knowledge
of the PIN. [1]
The detail of this attack is in IEEE paper:
BlueMirror: Reflections on Bluetooth Pairing and Provisioning Protocols
[2]
It's a reflection attack. The paper mentioned that attacker can induce
the attacked target to generate null link key (zero key) without PIN
code. In BR/EDR, the key generation is actually handled in the controller
which is below HCI.
A condition of this attack is that attacker should change the
BR_ADDR of his hacking device (Host B) to equal to the BR_ADDR with
the target device being attacked (Host A).
Thus, we reject the connection with device which has same BD_ADDR
both on HCI_Create_Connection and HCI_Connection_Request to prevent
the attack. A similar implementation also shows in btstack project.

commit ff70202b2d1ad522275c6aadc8c53519b6a22c57 upstream.
The goal is to keep the mark during a bpf_redirect(), like it is done for
legacy encapsulation / decapsulation, when there is no x-netns.
This was initially done in commit 213dd74aee76 ("skbuff: Do not scrub skb
mark within the same name space").
When the call to skb_scrub_packet() was added in dev_forward_skb() (commit
8b27f27797ca ("skb: allow skb_scrub_packet() to be used by tunnels")), the
second argument (xnet) was set to true to force a call to skb_orphan(). At
this time, the mark was always cleanned up by skb_scrub_packet(), whatever
xnet value was.
This call to skb_orphan() was removed later in commit
9c4c325252c5 ("skbuff: preserve sock reference when scrubbing the skb.").
But this 'true' stayed here without any real reason.
Let's correctly set xnet in ____dev_forward_skb(), this function has access
to the previous interface and to the new interface.

commit 3971442870713de527684398416970cf025b4f89 upstream.
The ravb_stop() should call cancel_work_sync(). Otherwise,
ravb_tx_timeout_work() is possible to use the freed priv after

CPU0 CPU1
ravb_tx_timeout()
ravb_remove()
unregister_netdev()
free_netdev(ndev)
// free priv
ravb_tx_timeout_work()
// use priv
unregister_netdev() will call .ndo_stop() so that ravb_stop() is
called. And, after phy_stop() is called, netif_carrier_off()
is also called. So that .ndo_tx_timeout() will not be called
after phy_stop().

[ Upstream commit 01f1ae2733e2bb4de92fefcea5fda847d92aede1 ]
The synchronize_irq(c->irq) will not return until the IRQ handler
mtk_uart_apdma_irq_handler() is completed. If the synchronize_irq()
holds a spin_lock and waits the IRQ handler to complete, but the
IRQ handler also needs the same spin_lock. The deadlock will happen.
The process is shown below:

| spin_lock_irqsave()
//hold the lock to wait |

This patch reorders the synchronize_irq(c->irq) outside the spin_lock
in order to mitigate the bug.

commit 427694cfaafa565a3db5c5ea71df6bc095dca92f upstream.
When NCM is used with hosts like Windows PC, it is observed that there are
multiple NTB's contained in one usb request giveback. Since the driver
unwraps the obtained request data assuming only one NTB is present, we
loose the subsequent NTB's present resulting in data loss.
Fix this by checking the parsed block length with the obtained data
length in usb request and continue parsing after the last byte of current
NTB.

commit 3061b6491f491197a35e14e49f805d661b02acd4 upstream.
For ARM processor, unaligned access to device memory is not allowed.
Method memcpy does not take care of alignment.
USB detection failure with the unalingned address of memory, with
below kernel crash. To fix the unalingned address kernel panic,
replace memcpy with memcpy_toio method.
Kernel crash:
