6744e02515 RDMA/bnxt_re: Fix incorrect AVID type in WQE structure
[ Upstream commit 9ab20f76ae9fad55ebaf36bdff04aea1c2552374 ]

Driver uses internal data structure to construct WQE frame.
It used avid type as u16 which can accommodate up to 64K AVs.
When outstanding AVID crosses 64K, driver truncates AVID and
hence it uses incorrect AVID to WR. This leads to WR failure
due to invalid AV ID and QP is moved to error state with reason
set to 19 (INVALID AVID). When RDMA CM path is used, this issue
hits QP1 and it is moved to error state

9b97db363b irqchip/gic-v4: Don't allow a VMOVP on a dying VPE
commit 1442ee0011983f0c5c4b92380e6853afb513841a upstream.

Kunkun Jiang reported that there is a small window of opportunity for
userspace to force a change of affinity for a VPE while the VPE has already
been unmapped, but the corresponding doorbell interrupt still visible in
/proc/irq/.

Plug the race by checking the value of vmapp_count, which tracks whether
the VPE is mapped ot not, and returning an error in this case.

This involves making vmapp_count common to both GICv4.1 and its v4.0
ancestor.

aad6868e15 parport: Proper fix for array out-of-bounds access
commit 02ac3a9ef3a18b58d8f3ea2b6e46de657bf6c4f9 upstream.

The recent fix for array out-of-bounds accesses replaced sprintf()
calls blindly with snprintf().  However, since snprintf() returns the
would-be-printed size, not the actually output size, the length
calculation can still go over the given limit.

Use scnprintf() instead of snprintf(), which returns the actually
output letters, for addressing the potential out-of-bounds access
properly.

26ca5dede5 xhci: Fix incorrect stream context type macro
commit 6599b6a6fa8060145046d0744456b6abdb3122a7 upstream.

The stream contex type (SCT) bitfield is used both in the stream context
data structure,  and in the 'Set TR Dequeue pointer' command TRB.
In both cases it uses bits 3:1

The SCT_FOR_TRB(p) macro used to set the stream context type (SCT) field
for the 'Set TR Dequeue pointer' command TRB incorrectly shifts the value
1 bit left before masking the three bits.

Fix this by first masking and rshifting, just like the similar
SCT_FOR_CTX(p) macro does

This issue has not been visibile as the lost bit 3 is only used with
secondary stream arrays (SSA). Xhci driver currently only supports using
a primary stream array with Linear stream addressing.

According to USB Spec 2.0 Section 5.7.3 Interrupt Transfer Packet Size
Constraints a interrupt transfer is considered complete when the size is 0
(ZPL) or < wMaxPacketSize:

 'When an interrupt transfer involves more data than can fit in one
 data payload of the currently established maximum size, all data
 payloads are required to be maximum-sized except for the last data
 payload, which will contain the remaining data. An interrupt transfer
 is complete when the endpoint does one of the following:

 • Has transferred exactly the amount of data expected
 • Transfers a packet with a payload size less than wMaxPacketSize or
 transfers a zero-length packet'

commit 530688e39c644543b71bdd9cb45fdfb458a28eaa upstream.

The opt3001 driver uses predetermined full-scale range values to
determine what exponent to use for event trigger threshold values.
The problem is that one of the values specified in the datasheet is
missing from the implementation. This causes larger values to be
scaled down to an incorrect exponent, effectively reducing the
maximum settable threshold value by a factor of 2.

Add missing full-scale range array value.

923da71956 iio: light: veml6030: fix IIO device retrieval from embedded device
commit c7c44e57750c31de43906d97813273fdffcf7d02 upstream.

The dev pointer that is received as an argument in the
in_illuminance_period_available_show function references the device
embedded in the IIO device, not in the i2c client.

dev_to_iio_dev() must be used to accessthe right data. The current
implementation leads to a segmentation fault on every attempt to read
the attribute because indio_dev gets a NULL assignment.

This bug has been present since the first appearance of the driver,
apparently since the last version (V6) before getting applied. A
constant attribute was used until then, and the last modifications might
have not been tested again.

commit c9e9746f275c45108f2b0633a4855d65d9ae0736 upstream.

The driver still uses the sensor resolution provided in the datasheet
until Rev. 1.6, 28-Apr-2022, which was updated with Rev 1.7,
28-Nov-2023. The original ambient light resolution has been updated from
0.0036 lx/ct to 0.0042 lx/ct, which is the value that can be found in
the current device datasheet.

Update the default resolution for IT = 100 ms and GAIN = 1/8 from the
original 4608 mlux/cnt to the current value from the "Resolution and
maximum detection range" table (Application Note 84367, page 5), 5376
mlux/cnt.

Currently if condition (!bo and !vmw_kms_srf_ok()) was met

err_out dereferences vfb if ret == 0, but in our case vfb is still NULL.

commit 28127dba64d8ae1a0b737b973d6d029908599611 upstream.

Include the encoder itself in its possible_clones bitmask.
In the past nothing validated that drivers were populating
possible_clones correctly, but that changed in commit
74d2aacbe840 ("drm: Validate encoder->possible_clones").
Looks like radeon never got the memo and is still not
following the rules 100% correctly.

This results in some warnings during driver initialization:

253e51ed4b s390/sclp_vt220: Convert newlines to CRLF instead of LFCR
commit dee3df68ab4b00fff6bdf9fc39541729af37307c upstream.

According to the VT220 specification the possible character combinations
sent on RETURN are only CR or CRLF [0].

	The Return key sends either a CR character (0/13) or a CR
	character (0/13) and an LF character (0/10), depending on the
	set/reset state of line feed/new line mode (LNM).

The sclp/vt220 driver however uses LFCR. This can confuse tools, for
example the kunit runner.

c25cfe7ca9 irqchip/gic-v3-its: Fix VSYNC referencing an unmapped VPE on GIC v4.1
commit 80e9963fb3b5509dfcabe9652d56bf4b35542055 upstream.

As per the GICv4.1 spec (Arm IHI 0069H, 5.3.19):

 "A VMAPP with {V, Alloc}=={0, x} is self-synchronizing, This means the ITS
  command queue does not show the command as consumed until all of its
  effects are completed."

Furthermore, VSYNC is allowed to deliver an SError when referencing a
non existent VPE.

By these definitions, a VMAPP followed by a VSYNC is a bug, as the
later references a VPE that has been unmapped by the former.

Fix it by eliding the VSYNC in this scenario.

f93e3153c5 net: macb: Avoid 20s boot delay by skipping MDIO bus registration for fixed-link PHY
commit d0c3601f2c4e12e7689b0f46ebc17525250ea8c3 upstream.

A boot delay was introduced by commit 79540d133ed6 ("net: macb: Fix
handling of fixed-link node"). This delay was caused by the call to
`mdiobus_register()` in cases where a fixed-link PHY was present. The
MDIO bus registration triggered unnecessary PHY address scans, leading
to a 20-second delay due to attempts to detect Clause 45 (C45)
compatible PHYs, despite no MDIO bus being attached.

The commit 79540d133ed6 ("net: macb: Fix handling of fixed-link node")
was originally introduced to fix a regression caused by commit
7897b071ac3b4 ("net: macb: convert to phylink"), which caused the driver
to misinterpret fixed-link nodes as PHY nodes. This resulted in warnings
like:
mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
...
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31

This patch reworks the logic to avoid registering and allocation of the
MDIO bus when:
  - The device tree contains a fixed-link node.
  - There is no "mdio" child node in the device tree.

If a child node named "mdio" exists, the MDIO bus will be registered to
support PHYs  attached to the MACB's MDIO bus. Otherwise, with only a
fixed-link, the MDIO bus is skipped.

Tested on a sama5d35 based system with a ksz8863 switch attached to
macb0.

f3d653f03e net: vrf: determine the dst using the original ifindex for multicast
commit f2575c8f404911da83f25b688e12afcf4273e640 upstream.

Multicast packets received on an interface bound to a VRF are marked as
belonging to the VRF and the skb device is updated to point to the VRF
device itself. This was fine even when a route was associated to a
device as when performing a fib table lookup 'oif' in fib6_table_lookup
(coming from 'skb->dev->ifindex' in ip6_route_input) was set to 0 when
FLOWI_FLAG_SKIP_NH_OIF was set.

With commit 40867d74c374 ("net: Add l3mdev index to flow struct and
avoid oif reset for port devices") this is not longer true and multicast
traffic is not received on the original interface.

Instead of adding back a similar check in fib6_table_lookup determine
the dst using the original ifindex for multicast VRF traffic. To make
things consistent across the function do the above for all strict
packets, which was the logic before commit 6f12fa775530 ("vrf: mark skb
for multicast or link-local as enslaved to VRF"). Note that reverting to
this behavior should be fine as the change was about marking packets
belonging to the VRF, not about their dst.

0486357541 nouveau/dmem: Fix vulnerability in migrate_to_ram upon copy error
commit 835745a377a4519decd1a36d6b926e369b3033e2 upstream.

The `nouveau_dmem_copy_one` function ensures that the copy push command is
sent to the device firmware but does not track whether it was executed
successfully.

In the case of a copy error (e.g., firmware or hardware failure), the
copy push command will be sent via the firmware channel, and
`nouveau_dmem_copy_one` will likely report success, leading to the
`migrate_to_ram` function returning a dirty HIGH_USER page to the user.

This can result in a security vulnerability, as a HIGH_USER page that may
contain sensitive or corrupted data could be returned to the user.

To prevent this vulnerability, we allocate a zero page. Thus, in case of
an error, a non-dirty (zero) page will be returned to the user.

324949d431 hwmon: (adm9240) Add missing dependency on REGMAP_I2C
[ Upstream commit 14849a2ec175bb8a2280ce20efe002bb19f1e274 ]

This driver requires REGMAP_I2C to be selected in order to get access to
regmap_config and devm_regmap_init_i2c. Add the missing dependency.

9fe9feaa4c slip: make slhc_remember() more robust against malicious packets
[ Upstream commit 7d3fce8cbe3a70a1c7c06c9b53696be5d5d8dd5c ]

syzbot found that slhc_remember() was missing checks against
malicious packets [1].

slhc_remember() only checked the size of the packet was at least 20,
which is not good enough.

We need to make sure the packet includes the IPv4 and TCP header
that are supposed to be carried.

Add iph and th pointers to make the code more readable.

8e4923ae31 net: Add l3mdev index to flow struct and avoid oif reset for port devices
[ Upstream commit 40867d74c374b235e14d839f3a77f26684feefe5 ]

The fundamental premise of VRF and l3mdev core code is binding a socket
to a device (l3mdev or netdev with an L3 domain) to indicate L3 scope.
Legacy code resets flowi_oif to the l3mdev losing any original port
device binding. Ben (among others) has demonstrated use cases where the
original port device binding is important and needs to be retained.
This patch handles that by adding a new entry to the common flow struct
that can indicate the l3mdev index for later rule and table matching
avoiding the need to reset flowi_oif.

In addition to allowing more use cases that require port device binds,
this patch brings a few datapath simplications:

1. l3mdev_fib_rule_match is only called when walking fib rules and
   always after l3mdev_update_flow. That allows an optimization to bail
   early for non-VRF type uses cases when flowi_l3mdev is not set. Also,
   only that index needs to be checked for the FIB table id.

2. l3mdev_update_flow can be called with flowi_oif set to a l3mdev
   (e.g., VRF) device. By resetting flowi_oif only for this case the
   FLOWI_FLAG_SKIP_NH_OIF flag is not longer needed and can be removed,
   removing several checks in the datapath. The flowi_iif path can be
   simplified to only be called if the it is not loopback (loopback can
   not be assigned to an L3 domain) and the l3mdev index is not already
   set.

3. Avoid another device lookup in the output path when the fib lookup
   returns a reject failure.

Note: 2 functional tests for local traffic with reject fib rules are
updated to reflect the new direct failure at FIB lookup time for ping
rather than the failure on packet path. The current code fails like this:

    HINT: Fails since address on vrf device is out of device scope
    COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
    ping: Warning: source address might be selected on device other than: eth1
    PING 172.16.3.1 (172.16.3.1) from 172.16.3.1 eth1: 56(84) bytes of data.

    --- 172.16.3.1 ping statistics ---
    1 packets transmitted, 0 received, 100% packet loss, time 0ms

where the test now directly fails:

    HINT: Fails since address on vrf device is out of device scope
    COMMAND: ip netns exec ns-A ping -c1 -w1 -I eth1 172.16.3.1
    ping: connect: No route to host

e28819c79a igb: Do not bring the device up after non-fatal error
[ Upstream commit 330a699ecbfc9c26ec92c6310686da1230b4e7eb ]

Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

537a6560b4 gpio: aspeed: Add the flush write to ensure the write complete.
[ Upstream commit 1bb5a99e1f3fd27accb804aa0443a789161f843c ]

Performing a dummy read ensures that the register write operation is fully
completed, mitigating any potential bus delays that could otherwise impact
the frequency of bitbang usage. E.g., if the JTAG application uses GPIO to
control the JTAG pins (TCK, TMS, TDI, TDO, and TRST), and the application
sets the TCK clock to 1 MHz, the GPIO's high/low transitions will rely on
a delay function to ensure the clock frequency does not exceed 1 MHz.
However, this can lead to rapid toggling of the GPIO because the write
operation is POSTed and does not wait for a bus acknowledgment.

All modern chips support and need the 10_100 bit set for supporting jumbo
frames on 10/100 ports, so instead of enabling it only for 583XX enable
it for everything except bcm63xx, where the bit is writeable, but does
nothing.

Tested on BCM53115, where jumbo frames were dropped at 10/100 speeds
without the bit set.

732af45018 net: dsa: b53: allow lower MTUs on BCM5325/5365
[ Upstream commit e4b294f88a32438baf31762441f3dd1c996778be ]

While BCM5325/5365 do not support jumbo frames, they do support slightly
oversized frames, so do not error out if requesting a supported MTU for
them.

b85cee905d net: dsa: b53: fix max MTU for BCM5325/BCM5365
[ Upstream commit ca8c1f71c10193c270f772d70d34b15ad765d6a8 ]

BCM5325/BCM5365 do not support jumbo frames, so we should not report a
jumbo frame mtu for them. But they do support so called "oversized"
frames up to 1536 bytes long by default, so report an appropriate MTU.

dd0861a3a4 net: dsa: b53: fix max MTU for 1g switches
[ Upstream commit 680a8217dc00dc7e7da57888b3c053289b60eb2b ]

JMS_MAX_SIZE is the ethernet frame length, not the MTU, which is payload
without ethernet headers.

According to the datasheets maximum supported frame length for most
gigabyte swithes is 9720 bytes, so convert that to the expected MTU when
using VLAN tagged frames.

cc2e77dddf net: dsa: b53: fix jumbo frame mtu check
[ Upstream commit 42fb3acf6826c6764ba79feb6e15229b43fd2f9f ]

JMS_MIN_SIZE is the full ethernet frame length, while mtu is just the
data payload size. Comparing these two meant that mtus between 1500 and
1518 did not trigger enabling jumbo frames.

So instead compare the set mtu ETH_DATA_LEN, which is equal to
JMS_MIN_SIZE - ETH_HLEN - ETH_FCS_LEN;

Also do a check that the requested mtu is actually greater than the
minimum length, else we do not need to enable jumbo frames.

In practice this only introduced a very small range of mtus that did not
work properly. Newer chips allow 2000 byte large frames by default, and
older chips allow 1536 bytes long, which is equivalent to an mtu of
1514. So effectivly only mtus of 1515~1517 were broken.

If phy_read_mmd() fails, the error code stored in 'bmsr' should be returned
instead of 'val' which is likely to be 0.
