The earlier bug fix misplaced the error-label when dealing with the
tpm2_create_primary() return value, which the original completely ignored.

Closes: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1087331

Signed-off-by: Jarkko Sakkinen <jarkko@kernel.org>
The initial HMAC session feature added TPM bus encryption and/or integrity
protection to various in-kernel TPM operations. This can cause performance
bottlenecks with IMA, as it heavily utilizes PCR extend operations.
In order to mitigate this performance issue, introduce a kernel
command-line parameter to the TPM driver for disabling the integrity
protection for PCR extend operations (i.e. TPM2_PCR_Extend).

The commit 4c39529663 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-cache
code.
The dm-cache code allocates a slab cache for each device. This commit
changes it to allocate just one slab cache in the module init function.
Signed-off-by: Mikulas Patocka <mpatocka@redhat.com>
Fixes: 4c39529663 ("slab: Warn on duplicate cache names when DEBUG_VM=y")
The commit 4c39529663 adds a warning about duplicate cache names if
CONFIG_DEBUG_VM is selected. These warnings are triggered by the dm-bufio
code. The dm-bufio code allocates a slab cache with each client. It is
not possible to preallocate the caches in the module init function
because the size of auxiliary per-buffer data is not known at this point.
So, this commit changes dm-bufio so that it appends a unique atomic value
to the cache name, to avoid the warnings.

This behaviour was discovered when testing xfstests generic/525 with the

Pull block fix from Jens Axboe:
"Single fix for an issue triggered with PROVE_RCU=y, with nvme using
the wrong iterators for an SRCU protected list"
* tag 'block-6.12-20241108' of git://git.kernel.dk/linux:
nvme/host: Fix RCU list traversal to use SRCU primitive
sched_ext dispatches tasks from the BPF scheduler from balance_scx() and
thus every pick_task_scx() call must be preceded by balance_scx(). While
this usually holds, due to a bug, there are cases where the fair class's
balance() returns true indicating that it has tasks to run on the CPU and
thus terminating balance() calls but fails to actually find the next task to
run when pick_task() is called. In such cases, pick_task_scx() can be called
without preceding balance_scx().
Detect this condition using SCX_RQ_BAL_PENDING flags. If detected, keep
running the previous task if possible and avoid stalling from entering idle
without balancing.

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205acd ("i2c: designware: fix __i2c_dw_disable() in
case master is holding SCL low"). Also check BIT(7)
MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when
IC_STAT_FOR_CLK_STRETCH is set.

Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.

arm64/sve: Discard stale CPU state when handling SVE traps
Hide KVM's pt_mode module param behind CONFIG_BROKEN, i.e. disable support
for virtualizing Intel PT via guest/host mode unless BROKEN=y. There are
myriad bugs in the implementation, some of which are fatal to the guest,
and others which put the stability and health of the host at risk.
For guest fatalities, the most glaring issue is that KVM fails to ensure
tracing is disabled, and *stays* disabled prior to VM-Enter, which is
necessary as hardware disallows loading (the guest's) RTIT_CTL if tracing
is enabled (enforced via a VMX consistency check). Per the SDM:
If the logical processor is operating with Intel PT enabled (if
IA32_RTIT_CTL.TraceEn = 1) at the time of VM entry, the "load
IA32_RTIT_CTL" VM-entry control must be 0.
On the host side, KVM doesn't validate the guest CPUID configuration
provided by userspace, and even worse, uses the guest configuration to
decide what MSRs to save/load at VM-Enter and VM-Exit. E.g. configuring
guest CPUID to enumerate more address ranges than are supported in hardware
will result in KVM trying to passthrough, save, and load non-existent MSRs,
which generates a variety of WARNs, ToPA ERRORs in the host, a potential
deadlock, etc.

Always set irr_pending (to true) when updating APICv status to fix a bug
where KVM fails to set irr_pending when userspace sets APIC state and
APICv is disabled, which ultimate results in KVM failing to inject the
pending interrupt(s) that userspace stuffed into the vIRR, until another
interrupt happens to be emulated by KVM.
Only the APICv-disabled case is flawed, as KVM forces apic->irr_pending to
be true if APICv is enabled, because not all vIRR updates will be visible
to KVM.
Hit the bug with a big hammer, even though strictly speaking KVM can scan
the vIRR and set/clear irr_pending as appropriate for this specific case.
The bug was introduced by commit 755c2bf878 ("KVM: x86: lapic: don't
touch irr_pending in kvm_apic_update_apicv when inhibiting it"), which as
the shortlog suggests, deleted code that updated irr_pending.
Before that commit, kvm_apic_update_apicv() did indeed scan the vIRR, with
with the crucial difference that kvm_apic_update_apicv() did the scan even
when APICv was being *disabled*, e.g. due to an AVIC inhibition.
struct kvm_lapic *apic = vcpu->arch.apic;
if (vcpu->arch.apicv_active) {
/* irr_pending is always true when apicv is activated. */
apic->irr_pending = true;
apic->isr_count = 1;
} else {
apic->irr_pending = (apic_search_irr(apic) != -1);
apic->isr_count = count_vectors(apic->regs + APIC_ISR);
}
And _that_ bug (clearing irr_pending) was introduced by commit b26a695a1d
("kvm: lapic: Introduce APICv update helper function"), prior to which KVM
unconditionally set irr_pending to true in kvm_apic_set_state(), i.e.
assumed that the new virtual APIC state could have a pending IRQ.
Furthermore, in addition to introducing this issue, commit 755c2bf878
also papered over the underlying bug: KVM doesn't ensure CPUs and devices
see APICv as disabled prior to searching the IRR. Waiting until KVM
emulates an EOI to update irr_pending "works", but only because KVM won't
emulate EOI until after refresh_apicv_exec_ctrl(), and there are plenty of
memory barriers in between. I.e. leaving irr_pending set is basically
hacking around bad ordering.
So, effectively revert to the pre-b26a695a1d78 behavior for state restore,
even though it's sub-optimal if no IRQs are pending, in order to provide a
minimal fix, but leave behind a FIXME to document the ugliness. With luck,
the ordering issue will be fixed and the mess will be cleaned up in the
not-too-distant future.

KVM x86 and selftests fixes for 6.12:
- Increase the timeout for the memslot performance selftest to avoid false
failures on arm64 and nested x86 platforms.
- Fix a goof in the guest_memfd selftest where a for-loop initialized a
bit mask to zero instead of BIT(0).
- Disable strict aliasing when building KVM selftests to prevent the
compiler from treating things like "u64 *" to "uint64_t *" cases as
undefined behavior, which can lead to nasty, hard to debug failures.
- Force -march=x86-64-v2 for KVM x86 selftests if and only if the uarch
is supported by the compiler.
- When emulating a guest TLB flush for a nested guest, flush vpid01, not
vpid02, if L2 is active but VPID is disabled in vmcs12, i.e. if L2 and
L1 are sharing VPID '0' (from L1's perspective).
- Fix a bug in the SNP initialization flow where KVM would return '0' to
userspace instead of -errno on failure.
A moderately large pile of small changes here, split fairly evenly
between fixes and ID additions/quirks and all of it driver specific.

ASoC: Fixes for v6.12
A moderately large pile of small changes here, split fairly evenly
between fixes and ID additions/quirks and all of it driver specific.
Here's a fix for a long-standing use-after-free in an io_edgeport debug
printk and some new modem device ids.
All have been in linux-next with no reported issues.
