commit 1cd4bc987abb2823836cbb8f887026011ccddc8a upstream.
Commit f58f45c1e5b9 ("vxlan: drop packets from invalid src-address")
has recently been added to vxlan mainly in the context of source
address snooping/learning so that when it is enabled, an entry in the
FDB is not being created for an invalid address for the corresponding
tunnel endpoint.
Before commit f58f45c1e5b9 vxlan was similarly behaving as geneve in
that it passed through whichever macs were set in the L2 header. It
turns out that this change in behavior breaks setups, for example,
Cilium with netkit in L3 mode for Pods as well as tunnel mode has been
passing before the change in f58f45c1e5b9 for both vxlan and geneve.
After mentioned change it is only passing for geneve as in case of
vxlan packets are dropped due to vxlan_set_mac() returning false as
source and destination macs are zero which for E/W traffic via tunnel
is totally fine.
Fix it by only opting into the is_valid_ether_addr() check in
vxlan_set_mac() when in fact source address snooping/learning is
actually enabled in vxlan. This is done by moving the check into
vxlan_snoop(). With this change, the Cilium connectivity test suite
passes again for both tunnel flavors.

One of our workloads (Postgres 14 + sysbench OLTP) regressed on newer
upstream kernel and on further investigation, it seems like the cause is
the always synchronous rstat flush in the count_shadow_nodes() added by
the commit f82e6bf9bb ("mm: memcg: use rstat for non-hierarchical
stats"). On further inspection it seems like we don't really need
accurate stats in this function as it was already approximating the amount
of appropriate shadow entries to keep for maintaining the refault
information. Since there is already 2 sec periodic rstat flush, we don't
need exact stats here. Let's ratelimit the rstat flush in this code path.

commit bd11dc4fb969ec148e50cd87f88a78246dbc4d0b upstream.
SO_KEEPALIVE support has been added a while ago, as part of a series
"adding SOL_SOCKET" support. To have a full control of this keep-alive
feature, it is important to also support TCP_KEEP* socket options at the
SOL_TCP level.
Supporting them on the setsockopt() part is easy, it is just a matter of
remembering each value in the MPTCP sock structure, and calling
tcp_sock_set_keep*() helpers on each subflow. If the value is not
modified (0), calling these helpers will not do anything. For the
getsockopt() part, the corresponding value from the MPTCP sock structure
or the default one is simply returned. All of this is very similar to
other TCP_* socket options supported by MPTCP.
It looks important for kernels supporting SO_KEEPALIVE, to also support
TCP_KEEP* options as well: some apps seem to (wrongly) consider that if
the former is supported, the latter ones will be supported as well. But
also, not having this simple and isolated change is preventing MPTCP
support in some apps, and libraries like GoLang [1]. This is why this
patch is seen as a fix.

commit ce4f78f1b53d3327fbd32764aa333bf05fb68818 upstream.
In the current riscv implementation, blocking syscalls like read() may
not correctly restart after being interrupted by ptrace. This problem
arises when the syscall restart process in arch_do_signal_or_restart()
is bypassed due to changes to the regs->cause register, such as an
ebreak instruction.
Steps to reproduce:
1. Interrupt the tracee process with PTRACE_SEIZE & PTRACE_INTERRUPT.
2. Backup original registers and instruction at new_pc.
3. Change pc to new_pc, and inject an instruction (like ebreak) to this
address.
4. Resume with PTRACE_CONT and wait for the process to stop again after
executing ebreak.
5. Restore original registers and instructions, and detach from the
tracee process.
6. Now the read() syscall in tracee will return -1 with errno set to
ERESTARTSYS.
Specifically, during an interrupt, the regs->cause changes from
EXC_SYSCALL to EXC_BREAKPOINT due to the injected ebreak, which is
inaccessible via ptrace so we cannot restore it. This alteration breaks
the syscall restart condition and ends the read() syscall with an
ERESTARTSYS error. According to include/linux/errno.h, it should never
be seen by user programs. X86 can avoid this issue as it checks the
syscall condition using a register (orig_ax) exposed to user space.
Arm64 handles syscall restart before calling get_signal, where it could
be paused and inspected by ptrace/debugger.
This patch adjusts the riscv implementation to arm64 style, which also
checks syscall using a kernel register (syscallno). It ensures the
syscall restart process is not bypassed when changes to the cause
register occur, providing more consistent behavior across various
architectures.

The referenced commit moved the setting of the Autoneg and pause bits
early in sfp_parse_support(). However, we check whether the modes are
empty before using the bitrate to set some modes. Setting these bits
so early causes that test to always be false, preventing this working,
and thus some modules that used to work no longer do.
Move them just before the call to the quirk.

Don't cross a mountpoint that explicitly specifies a backup volume
(target is <vol>.backup) when starting from a backup volume.
It it not uncommon to mount a volume's backup directly in the volume
itself. This can cause tools that are not paying attention to get
into a loop mounting the volume onto itself as they attempt to
traverse the tree, leading to a variety of problems.
This doesn't prevent the general case of loops in a sequence of
mountpoints, but addresses a common special case in the same way
as other afs clients.

commit 67380251e8bbd3302c64fea07f95c31971b91c22 upstream.
Requesting a retune before switching to the RPMB partition has been
observed to cause CRC errors on the RPMB reads (-EILSEQ).
Since RPMB reads can not be retried, the clients would be directly
affected by the errors.
This commit disables the retune request prior to switching to the RPMB
partition: mmc_retune_pause() no longer triggers a retune before the
pause period begins.
This was verified with the sdhci-of-arasan driver (ZynqMP) configured
for HS200 using two separate eMMC cards (DG4064 and 064GB2). In both
cases, the error was easy to reproduce triggering every few tenths of
reads.
With this commit, systems that were utilizing OP-TEE to access RPMB
variables will experience an enhanced performance. Specifically, when
OP-TEE is configured to employ RPMB as a secure storage solution, it not
only writes the data but also the secure filesystem within the
partition. As a result, retrieving any variable involves multiple RPMB
reads, typically around five.
For context, on ZynqMP, each retune request consumed approximately
8ms. Consequently, reading any RPMB variable used to take at the very
minimum 40ms.
After droping the need to retune before switching to the RPMB partition,
this is no longer the case.

When both hwmon and hwmon drvdata (on which hwmon depends) are device
managed resources, the expectation, on device unbind, is that hwmon will be
released before drvdata. However, in i915 there are two separate code
paths, which both release either drvdata or hwmon and either can be
released before the other. These code paths (for device unbind) are as
follows (see also the bug referenced below):
Call Trace:

unbind_store+0x9c/0xb0
This means that in i915, if use devm, we cannot gurantee that hwmon will
always be released before drvdata. Which means that we have a uaf if hwmon
sysfs is accessed when drvdata has been released but hwmon hasn't.
The only way out of this seems to be do get rid of devm_ and release/free
everything explicitly during device unbind.

Their stacks overlap with their pt_regs, so both may get corrupted.
Similar issue has been fixed for the primary hart, see c7cdd96eca
("riscv: prevent stack corruption by reserving task_pt_regs(p) early").
However that fix was not propagated to the secondary harts. The problem
has been noticed in some CPU hotplug tests with V enabled. The function
smp_callin stored several registers on stack, corrupting top of pt_regs
structure including status field. As a result, kernel attempted to save
or restore inexistent V context.

commit a6c11c0a5235fb144a65e0cb2ffd360ddc1f6c32 upstream.
The absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness of
interrupt affinity reconfiguration via procfs. Instead, the change is
deferred until the next instance of the interrupt being triggered on the
original CPU.
When the interrupt next triggers on the original CPU, the new affinity is
enforced within __irq_move_irq(). A vector is allocated from the new CPU,
but the old vector on the original CPU remains and is not immediately
reclaimed. Instead, apicd->move_in_progress is flagged, and the reclaiming
process is delayed until the next trigger of the interrupt on the new CPU.
Upon the subsequent triggering of the interrupt on the new CPU,
irq_complete_move() adds a task to the old CPU's vector_cleanup list if it
remains online. Subsequently, the timer on the old CPU iterates over its
vector_cleanup list, reclaiming old vectors.
However, a rare scenario arises if the old CPU is outgoing before the
interrupt triggers again on the new CPU.
In that case irq_force_complete_move() is not invoked on the outgoing CPU
to reclaim the old apicd->prev_vector because the interrupt isn't currently
affine to the outgoing CPU, and irq_needs_fixup() returns false. Even
though __vector_schedule_cleanup() is later called on the new CPU, it
doesn't reclaim apicd->prev_vector; instead, it simply resets both
apicd->move_in_progress and apicd->prev_vector to 0.
As a result, the vector remains unreclaimed in vector_matrix, leading to a
CPU vector leak.
To address this issue, move the invocation of irq_force_complete_move()
before the irq_needs_fixup() call to reclaim apicd->prev_vector, if the
interrupt is currently or used to be affine to the outgoing CPU.
Additionally, reclaim the vector in __vector_schedule_cleanup() as well,
following a warning message, although theoretically it should never see
apicd->move_in_progress with apicd->prev_cpu pointing to an offline CPU.

Drop KVM's propagation of GuestPhysBits (CPUID leaf 80000008, EAX[23:16])
to HostPhysBits (same leaf, EAX[7:0]) when advertising the address widths
to userspace via KVM_GET_SUPPORTED_CPUID.
Per AMD, GuestPhysBits is intended for software use, and physical CPUs do
not set that field. I.e. GuestPhysBits will be non-zero if and only if
KVM is running as a nested hypervisor, and in that case, GuestPhysBits is
NOT guaranteed to capture the CPU's effective MAXPHYADDR when running with
TDP enabled.
E.g. KVM will soon use GuestPhysBits to communicate the CPU's maximum
*addressable* guest physical address, which would result in KVM under-
reporting PhysBits when running as an L1 on a CPU with MAXPHYADDR=52,
but without 5-level paging.

commit 199f968f1484a14024d0d467211ffc2faf193eb4 upstream.
Arul, Mateusz, Imcarneiro91, and Aman reported a regression caused by
07eab0901e ("efi/x86: Remove EfiMemoryMappedIO from E820 map"). On the
Lenovo Legion 9i laptop, that commit removes the ECAM area from E820, which
means the early E820 validation fails, which means we don't enable ECAM in
the "early MCFG" path.
The static MCFG table describes ECAM without depending on the ACPI
interpreter. Many Legion 9i ACPI methods rely on that, so they fail when
PCI config access isn't available, resulting in the embedded controller,
PS/2, audio, trackpad, and battery devices not being detected. The _OSC
method also fails, so Linux can't take control of the PCIe hotplug, PME,
and AER features:

Per PCI Firmware r3.3, sec 4.1.2, ECAM space must be reserved by a PNP0C02
resource, but there's no requirement to mention it in E820, so we shouldn't
look at E820 to validate the ECAM space described by MCFG.
In 2006, 946f2ee5c7 ("[PATCH] i386/x86-64: Check that MCFG points to an
e820 reserved area") added a sanity check of E820 to work around buggy MCFG
tables, but that over-aggressive validation causes failures like this one.
Keep the E820 validation check for machines older than 2016, an arbitrary
ten years after 946f2ee5c7, so machines that depend on it don't break.
Skip the early E820 check for 2016 and newer BIOSes since there's no
requirement to describe ECAM in E820.

commit 15aa8fb852f995dd234a57f12dfb989044968bb6 upstream.
The legacy decompressor has elaborate logic to ensure that the
randomized physical placement of the decompressed kernel image does not
conflict with any memory reservations, including ones specified on the
command line using mem=, memmap=, efi_fake_mem= or hugepages=, which are
taken into account by the kernel proper at a later stage.
When booting in EFI mode, it is the firmware's job to ensure that the
chosen range does not conflict with any memory reservations that it
knows about, and this is trivially achieved by using the firmware's
memory allocation APIs.
That leaves reservations specified on the command line, though, which
the firmware knows nothing about, as these regions have no other special
significance to the platform. Since commit
a1b87d54f4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot")
these reservations are not taken into account when randomizing the
physical placement, which may result in conflicts where the memory
cannot be reserved by the kernel proper because its own executable image
resides there.
To avoid having to duplicate or reuse the existing complicated logic,
disable physical KASLR entirely when such overrides are specified. These
are mostly diagnostic tools or niche features, and physical KASLR (as
opposed to virtual KASLR, which is much more important as it affects the
memory addresses observed by code executing in the kernel) is something
we can live without.

Currently ALSA timer doesn't have the lower limit of the start tick
time, and it allows a very small size, e.g. 1 tick with 1ns resolution
for hrtimer. Such a situation may lead to an unexpected RCU stall,
where the callback repeatedly queuing the expire update, as reported
by fuzzer.
This patch introduces a sanity check of the timer start tick time, so
that the system returns an error when a too small start size is set.
As of this patch, the lower limit is hard-coded to 100us, which is
small enough but can still work somehow.

device tree. This happens with qemu when run without the '-name'
option. The message also lacks a newline. Remove it.

We fixed the incorrect UMP type for system messages in the recent
commit, but it missed one place in system_ev_to_ump_midi1().
Fix it now.

[ Upstream commit 2dc8b1e7177d4f49f492ce648440caf2de0c3616 ]
The driver overrides the NUMA node id of the device regardless of
whether it knows its correct value (often setting it to -1 even though
the node id is advertised in 'struct device'). This can lead to
suboptimal configurations.
This patch fixes this behavior and makes the shared memory allocation
functions use the NUMA node id advertised by the underlying device.
