[PATCH 5.15 02/45] arm64: kexec_file: use more system keyrings to verify kernel image signature

From: Coiby Xu <coxu@redhat.com>

[ Upstream commit 0d519cadf75184a24313568e7f489a7fc9b1be3b ]

Currently, when loading a kernel image via the kexec_file_load() system
call, arm64 can only use the .builtin_trusted_keys keyring to verify
a signature whereas x86 can use three more keyrings i.e.
.secondary_trusted_keys, .machine and .platform keyrings. For example,
one resulting problem is kexec'ing a kernel image  would be rejected
with the error "Lockdown: kexec: kexec of unsigned images is restricted;
see man kernel_lockdown.7".

This patch set enables arm64 to make use of the same keyrings as x86 to
verify the signature kexec'ed kernel image.

[PATCH 5.15 03/45] serial: atmel: remove redundant assignment in rs485_config

[Greg Kroah-Hartman]

From: Lino Sanfilippo <LinoSanfilippo@gmx.de>

[ Upstream commit 60efd0513916f195dd85bfbf21653f74f9ab019c ]

In uart_set_rs485_config() the serial core already assigns the passed
serial_rs485 struct to the uart port.

So remove the assignment from the drivers rs485_config() function to avoid
redundancy.

[PATCH 5.15 04/45] tty: serial: atmel: Preserve previous USART mode if RS485 disabled

[Greg Kroah-Hartman]

From: Sergiu Moga <sergiu.moga@microchip.com>

[ Upstream commit 692a8ebcfc24f4a5bea0eb2967e450f584193da6 ]

Whenever the atmel_rs485_config() driver method would be called,
the USART mode is reset to normal mode before even checking if
RS485 flag is set, thus resulting in losing the previous USART
mode in the case where the checking fails.

Some tools, such as `linux-serial-test`, lead to the driver calling
this method when doing the setup of the serial port: after setting the
port mode (Hardware Flow Control, Normal Mode, RS485 Mode, etc.),
`linux-serial-test` tries to enable/disable RS485 depending on
the commandline arguments that were passed.

Example of how this issue could reveal itself:
When doing a serial communication with Hardware Flow Control through
`linux-serial-test`, the tool would lead to the driver roughly doing
the following:
- set the corresponding bit to 1 (ATMEL_US_USMODE_HWHS bit in the
ATMEL_US_MR register) through the atmel_set_termios() to enable
Hardware Flow Control
- disable RS485 through the atmel_config_rs485() method
Thus, when the latter is called, the mode will be reset and the
previously set bit is unset, leaving USART in normal mode instead of
the expected Hardware Flow Control mode.

This fix ensures that this reset is only done if the checking for
RS485 succeeds and that the previous mode is preserved otherwise.

From: João H. Spies <jhlspies@gmail.com>

Switching between falling/rising edges for IRQ_TYPE_EDGE_BOTH on pins that
require debounce can cause the device to lose events due to a desync
between pin state and irq type.

This problem is resolved by switching between IRQ_TYPE_LEVEL_LOW and
IRQ_TYPE_LEVEL_HIGH instead.

[PATCH 5.15 13/45] drm/meson: Fix OSD1 RGB to YCbCr coefficient

From: Stuart Menefy <stuart.menefy@mathembedded.com>

[ Upstream commit 6463d3930ba5b6addcfc8f80a4543976a2fc7656 ]

VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
not 16-28.

Without this the output tends to have a pink hue, changing it results
in better color accuracy.

The vendor kernel doesn't use this register. However the code which
sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
different style of registers for configuring some of the other matrices,
which do use bits 16-28 for this coefficient, but those have names
ending in MATRIX_COEF22_30, and this is not one of those.

Today blk_queue_enter() and __bio_queue_enter() return -EBUSY for the
nowait code path. This is not correct: they should return -EAGAIN
instead.

This problem was detected by fio. The following command exposed the
above problem:

t/io_uring -p0 -d128 -b4096 -s32 -c32 -F1 -B0 -R0 -X1 -n24 -P1 -u1 -O0 /dev/ng0n1

[PATCH 5.15 16/45] of/device: Fix up of_dma_configure_id() stub

[Greg Kroah-Hartman]

From: Thierry Reding <treding@nvidia.com>

commit 40bfe7a86d84cf08ac6a8fe2f0c8bf7a43edd110 upstream.

Since the stub version of of_dma_configure_id() was added in commit
a081bd4af4ce ("of/device: Add input id to of_dma_configure()"), it has
not matched the signature of the full function, leading to build failure
reports when code using this function is built on !OF configurations.

[PATCH 5.15 17/45] cifs: revalidate mapping when doing direct writes

[Greg Kroah-Hartman]

From: Ronnie Sahlberg <lsahlber@redhat.com>

commit 7500a99281dfed2d4a84771c933bcb9e17af279b upstream.

Kernel bugzilla: 216301

When doing direct writes we need to also invalidate the mapping in case
we have a cached copy of the affected page(s) in memory or else
subsequent reads of the data might return the old/stale content
before we wrote an update to the server.

[PATCH 5.15 19/45] cifs: always initialize struct msghdr smb_msg completely

From: Stefan Metzmacher <metze@samba.org>

commit bedc8f76b3539ac4f952114b316bcc2251e808ce upstream.

So far we were just lucky because the uninitialized members
of struct msghdr are not used by default on a SOCK_STREAM tcp
socket.

But as new things like msg_ubuf and sg_from_iter where added
recently, we should play on the safe side and avoid potention
problems in future.

[PATCH 5.15 20/45] parisc: Allow CONFIG_64BIT with ARCH=parisc

[Greg Kroah-Hartman]

From: Helge Deller <deller@gmx.de>

commit 805ce8614958c925877ba6b6dc26cdf9f8800474 upstream.

The previous patch triggered a build failure for the debian kernel,
which has CONFIG_64BIT enabled, uses the CROSS_COMPILER environment
variable and uses ARCH=parisc to configure the kernel for 64-bit
support.

This patch weakens the previous patch while keeping the recommended way
to configure the kernel with:
    ARCH=parisc     -> build 32-bit kernel
    ARCH=parisc64   -> build 64-bit kernel
while adding the possibility for debian to configure a 64-bit kernel
even if ARCH=parisc is set (PA8X00 CPU has to be selected and
CONFIG_64BIT needs to be enabled).

The downside of this patch is, that we now have a small window open
again where people may get it wrong: if they enable CONFIG_64BIT and try
to compile with a 32-bit compiler.

[PATCH 5.15 22/45] drm/amdgpu: Dont enable LTR if not supported

[Greg Kroah-Hartman]

From: Lijo Lazar <lijo.lazar@amd.com>

commit 6c20490663553cd7e07d8de8af482012329ab9d6 upstream.

As per PCIE Base Spec r4.0 Section 6.18
'Software must not enable LTR in an Endpoint unless the Root Complex
and all intermediate Switches indicate support for LTR.'

This fixes the Unsupported Request error reported through AER during
ASPM enablement.

Link: https://bugzilla.kernel.org/show_bug.cgi?id=216455

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.

[PATCH 5.15 23/45] drm/amdgpu: move nbio ih_doorbell_range() into ih code for vega

[Greg Kroah-Hartman]

From: Alex Deucher <alexander.deucher@amd.com>

commit dc1d85cb790f2091eea074cee24a704b2d6c4a06 upstream.

This mirrors what we do for other asics and this way we are
sure the ih doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  In this case IH is initialized before GFX,
so there should be no issue.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.

[PATCH 5.15 24/45] drm/amdgpu: move nbio sdma_doorbell_range() into sdma code for vega

[Greg Kroah-Hartman]

From: Alex Deucher <alexander.deucher@amd.com>

commit e3163bc8ffdfdb405e10530b140135b2ee487f89 upstream.

This mirrors what we do for other asics and this way we are
sure the sdma doorbell range is properly initialized.

There is a comment about the way doorbells on gfx9 work that
requires that they are initialized for other IPs before GFX
is initialized.  However, the statement says that it applies to
multimedia as well, but the VCN code currently initializes
doorbells after GFX and there are no known issues there.  In my
testing at least I don't see any problems on SDMA.

This is a prerequisite for fixing the Unsupported Request error
reported through AER during driver load.

Link: https://bugzilla.kernel.org/show_bug.cgi?id=216373

The error was unnoticed before and got visible because of the commit
referenced below. This doesn't fix anything in the commit below, rather
fixes the issue in amdgpu exposed by the commit. The reference is only
to associate this commit with below one so that both go together.

Fixes: 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")

[PATCH 5.15 25/45] binder: remove inaccurate mmap_assert_locked()

[Greg Kroah-Hartman]

From: Carlos Llamas <cmllamas@google.com>

Acquiring the mmap_lock during exit_mmap() was only added recently in
v5.17 by commit 64591e8605d6 ("mm: protect free_pgtables with mmap_lock
write lock in exit_mmap"). Soon after, asserts for holding this lock
were added to the binder_alloc_set_vma() callback by the following two
fix commits in mainline: commit b0cab80ecd54 ("android: binder: fix
lockdep check on clearing vma") and commit a43cfc87caaf ("android:
binder: stop saving a pointer to the VMA").

These two fix commits were picked for stable trees including v5.15 were
unfortunately the mmap_lock is not held during exit_mmap() yet and this
unmet dependency leads to the following BUG report:

not needed here as the mm->mm_users has dropped to zero at this point.

[PATCH 5.15 26/45] video: fbdev: i740fb: Error out if pixclock equals zero

[Greg Kroah-Hartman]

From: Zheyu Ma <zheyuma97@gmail.com>

commit 15cf0b82271b1823fb02ab8c377badba614d95d5 upstream.

The userspace program could pass any values to the driver through
ioctl() interface. If the driver doesn't check the value of 'pixclock',
it may cause divide error.

Fix this by checking whether 'pixclock' is zero in the function
i740fb_check_var().

The following log reveals it:

[PATCH 5.15 29/45] regulator: pfuze100: Fix the global-out-of-bounds access in pfuze100_regulator_probe()

[Greg Kroah-Hartman]

From: Xiaolei Wang <xiaolei.wang@windriver.com>

[ Upstream commit 78e1e867f44e6bdc72c0e6a2609a3407642fb30b ]

The pfuze_chip::regulator_descs is an array of size
PFUZE100_MAX_REGULATOR, the pfuze_chip::pfuze_regulators
is the pointer to the real regulators of a specific device.
The number of real regulator is supposed to be less than
the PFUZE100_MAX_REGULATOR, so we should use the size of
'regulator_num * sizeof(struct pfuze_regulator)' in memcpy().
This fixes the out of bounds access bug reported by KASAN.

[PATCH 5.15 30/45] scsi: lpfc: Return DID_TRANSPORT_DISRUPTED instead of DID_REQUEUE

[Greg Kroah-Hartman]

From: Hannes Reinecke <hare@suse.de>

[ Upstream commit c0a50cd389c3ed54831e240023dd12bafa56b3a6 ]

When the driver hits an internal error condition returning DID_REQUEUE the
I/O will be retried on the same ITL nexus.  This will inhibit multipathing,
resulting in endless retries even if the error could have been resolved by
using a different ITL nexus.  Return DID_TRANSPORT_DISRUPTED to allow for
multipath to engage and route I/O to another ITL nexus.

[PATCH 5.15 31/45] rxrpc: Fix local destruction being repeated

[Greg Kroah-Hartman]

From: David Howells <dhowells@redhat.com>

[ Upstream commit d3d863036d688313f8d566b87acd7d99daf82749 ]

If the local processor work item for the rxrpc local endpoint gets requeued
by an event (such as an incoming packet) between it getting scheduled for
destruction and the UDP socket being closed, the rxrpc_local_destroyer()
function can get run twice.  The second time it can hang because it can end
up waiting for cleanup events that will never happen.

[PATCH 5.15 33/45] wifi: mac80211_hwsim: check length for virtio packets

[Greg Kroah-Hartman]

From: Soenke Huster <soenke.huster@eknoes.de>

[ Upstream commit 8c0427842aaef161a38ac83b7e8d8fe050b4be04 ]

An invalid packet with a length shorter than the specified length in the
netlink header can lead to use-after-frees and slab-out-of-bounds in the
processing of the netlink attributes, such as the following:

  BUG: KASAN: slab-out-of-bounds in __nla_validate_parse+0x1258/0x2010

Discarding packets with an invalid length solves this.
Therefore, skb->len must be set at reception.

[PATCH 5.15 37/45] afs: Return -EAGAIN, not -EREMOTEIO, when a file already locked

From: David Howells <dhowells@redhat.com>

[ Upstream commit 0066f1b0e27556381402db3ff31f85d2a2265858 ]

When trying to get a file lock on an AFS file, the server may return
UAEAGAIN to indicate that the lock is already held.  This is currently
translated by the default path to -EREMOTEIO.

Translate it instead to -EAGAIN so that we know we can retry it.

[PATCH 5.15 39/45] drm/panfrost: devfreq: set opp to the recommended one to configure regulator

[Greg Kroah-Hartman]

From: Clément Péron <peron.clem@gmail.com>

[ Upstream commit d76034a427a2660b080bc155e4fd8f6393eefb48 ]

Enabling panfrost GPU OPP with dynamic regulator will make OPP
responsible to enable and configure it.

Unfortunately OPP configure and enable the regulator when an OPP
is asked to be set, which is not the case during
panfrost_devfreq_init().

This leave the regulator unconfigured and if no GPU load is
triggered, no OPP is asked to be set which make the regulator framework
switching it off during regulator_late_cleanup() without
noticing and therefore make the board hang as any access to GPU
memory space make bus locks up.

Call dev_pm_opp_set_opp() with the recommend OPP in
panfrost_devfreq_init() to enable the regulator, this will properly
configure and enable the regulator and will avoid any switch off
by regulator_late_cleanup().

From: Youling Tang <tangyouling@loongson.cn>

[ Upstream commit c17a2538704f926ee4d167ba625e09b1040d8439 ]

When System.map was generated, the kernel used mksysmap to filter the
kernel symbols, we need to filter "L0" symbols in LoongArch architecture.

$ cat System.map | grep L0
9000000000221540 t L0

The L0 symbol exists in System.map, but not in .tmp_System.map. When
"cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms
data" error message in link-vmlinux.sh script.

[PATCH 5.15 41/45] video: fbdev: pxa3xx-gcu: Fix integer overflow in pxa3xx_gcu_write

[Greg Kroah-Hartman]

From: Hyunwoo Kim <imv4bel@gmail.com>

[ Upstream commit a09d2d00af53b43c6f11e6ab3cb58443c2cac8a7 ]

In pxa3xx_gcu_write, a count parameter of type size_t is passed to words of
type int.  Then, copy_from_user() may cause a heap overflow because it is used
as the third argument of copy_from_user().

[PATCH 5.15 42/45] net: Find dst with sks xfrm policy not ctl_sk

[Greg Kroah-Hartman]

From: sewookseo <sewookseo@google.com>

commit e22aa14866684f77b4f6b6cae98539e520ddb731 upstream.

If we set XFRM security policy by calling setsockopt with option
IPV6_XFRM_POLICY, the policy will be stored in 'sock_policy' in 'sock'
struct. However tcp_v6_send_response doesn't look up dst_entry with the
actual socket but looks up with tcp control socket. This may cause a
problem that a RST packet is sent without ESP encryption & peer's TCP
socket can't receive it.
This patch will make the function look up dest_entry with actual socket,
if the socket has XFRM policy(sock_policy), so that the TCP response
packet via this function can be encrypted, & aligned on the encrypted
TCP socket.

Tested: We encountered this problem when a TCP socket which is encrypted
in ESP transport mode encryption, receives challenge ACK at SYN_SENT
state. After receiving challenge ACK, TCP needs to send RST to
establish the socket at next SYN try. But the RST was not encrypted &
peer TCP socket still remains on ESTABLISHED state.
So we verified this with test step as below.
[Test step]
1. Making a TCP state mismatch between client(IDLE) & server(ESTABLISHED).
2. Client tries a new connection on the same TCP ports(src & dst).
3. Server will return challenge ACK instead of SYN,ACK.
4. Client will send RST to server to clear the SOCKET.
5. Client will retransmit SYN to server on the same TCP ports.
[Expected result]
The TCP connection should be established.

[PATCH 5.15 43/45] KVM: SEV: add cache flush to solve SEV cache incoherency issues

[Greg Kroah-Hartman]

From: Mingwei Zhang <mizhang@google.com>

commit 683412ccf61294d727ead4a73d97397396e69a6b upstream.

Flush the CPU caches when memory is reclaimed from an SEV guest (where
reclaim also includes it being unmapped from KVM's memslots).  Due to lack
of coherency for SEV encrypted memory, failure to flush results in silent
data corruption if userspace is malicious/broken and doesn't ensure SEV
guest memory is properly pinned and unpinned.

Cache coherency is not enforced across the VM boundary in SEV (AMD APM
vol.2 Section 15.34.7). Confidential cachelines, generated by confidential
VM guests have to be explicitly flushed on the host side. If a memory page
containing dirty confidential cachelines was released by VM and reallocated
to another user, the cachelines may corrupt the new user at a later time.

KVM takes a shortcut by assuming all confidential memory remain pinned
until the end of VM lifetime. Therefore, KVM does not flush cache at
mmu_notifier invalidation events. Because of this incorrect assumption and
the lack of cache flushing, malicous userspace can crash the host kernel:
creating a malicious VM and continuously allocates/releases unpinned
confidential memory pages when the VM is running.

Add cache flush operations to mmu_notifier operations to ensure that any
physical memory leaving the guest VM get flushed. In particular, hook
mmu_notifier_invalidate_range_start and mmu_notifier_release events and
flush cache accordingly. The hook after releasing the mmu lock to avoid
contention with other vCPUs.
