KVM: arm64: nvhe: Ignore SVE hint in SMCCC function ID
When SVE is enabled, the host may set bit 16 in SMCCC function IDs, a
hint that indicates an unused SVE state. At the moment NVHE doesn't
account for this bit when inspecting the function ID, and rejects most
calls. Clear the hint bit before comparing function IDs.
About version compatibility: the host's PSCI driver initially probes the
firmware for a SMCCC version number. If the firmware implements a
protocol recent enough (1.3), subsequent SMCCC calls have the hint bit
set. Since the hint bit was reserved in earlier versions of the
protocol, clearing it is fine regardless of the version in use.
When a new hint is added to the protocol in the future, it will be added
to ARM_SMCCC_CALL_HINTS and NVHE will handle it straight away. This
patch only clears known hints and leaves reserved bits as is, because
future SMCCC versions could use reserved bits as modifiers for the
function ID, rather than hints.

tracing/synthetic: Fix order of struct trace_dynamic_info
To make handling BIG and LITTLE endian better the offset/len of dynamic
fields of the synthetic events was changed into a structure of:
struct trace_dynamic_info {
#ifdef CONFIG_CPU_BIG_ENDIAN
u16 offset;
u16 len;
#else
u16 len;
u16 offset;
#endif
};
to replace the manual changes of:
data_offset = offset & 0xffff;
data_offest = len << 16;
But if you look closely, the above is:
<len> << 16 | offset
Which in little endian would be in memory:
offset_lo offset_hi len_lo len_hi
and in big endian:
len_hi len_lo offset_hi offset_lo
Which if broken into a structure would be:
struct trace_dynamic_info {
#ifdef CONFIG_CPU_BIG_ENDIAN
u16 len;
u16 offset;
#else
u16 offset;
u16 len;
#endif
};
Which is the opposite of what was defined.
Fix this and just to be safe also add "__packed".

Add 'const' to the definition of the 'trip' argument of the .get_trend() thermal zone callback to indicate that the trip point passed to it should not be modified by it and adjust the callback functions implementing it, thermal_get_trend() in the ACPI thermal driver and __ti_thermal_get_trend(), accordingly.

wifi: cfg80211: fix cqm_config access race
Max Schulze reports crashes with brcmfmac. The reason seems
to be a race between userspace removing the CQM config and
the driver calling cfg80211_cqm_rssi_notify(), where if the
data is freed while cfg80211_cqm_rssi_notify() runs it will
crash since it assumes wdev->cqm_config is set. This can't
be fixed with a simple non-NULL check since there's nothing
we can do for locking easily, so use RCU instead to protect
the pointer, but that requires pulling the updates out into
an asynchronous worker so they can sleep and call back into
the driver.
Since we need to change the free anyway, also change it to
go back to the old settings if changing the settings fails.

wifi: cfg80211/mac80211: hold link BSSes when assoc fails for MLO connection
When connect to MLO AP with more than one link, and the assoc response of
AP is not success, then cfg80211_unhold_bss() is not called for all the
links' cfg80211_bss except the primary link which means the link used by
the latest successful association request. Thus the hold value of the
cfg80211_bss is not reset to 0 after the assoc fail, and then the
__cfg80211_unlink_bss() will not be called for the cfg80211_bss by
__cfg80211_bss_expire().
Then the AP always looks exist even the AP is shutdown or reconfigured
to another type, then it will lead error while connecting it again.
The detail info are as below.
When connect with muti-links AP, cfg80211_hold_bss() is called by
cfg80211_mlme_assoc() for each cfg80211_bss of all the links. When
assoc response from AP is not success(such as status_code==1), the
ieee80211_link_data of non-primary link(sdata->link[link_id]) is NULL
because ieee80211_assoc_success()->ieee80211_vif_update_links() is
not called for the links.
Then struct cfg80211_rx_assoc_resp resp in cfg80211_rx_assoc_resp() and
struct cfg80211_connect_resp_params cr in __cfg80211_connect_result()
will only have the data of the primary link, and finally function
cfg80211_connect_result_release_bsses() only call cfg80211_unhold_bss()
for the primary link. Then cfg80211_bss of the other links will never free
because its hold is always > 0 now.
Hence assign value for the bss and status from assoc_data since it is
valid for this case. Also assign value of addr from assoc_data when the
link is NULL because the addrs of assoc_data and link both represent the
local link addr and they are same value for success connection.

ata: libata: disallow dev-initiated LPM transitions to unsupported states
In AHCI 1.3.1, the register description for CAP.SSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Slumber state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Slumber requests."
In AHCI 1.3.1, the register description for CAP.PSC:
"When cleared to ‘0’, software must not allow the HBA to initiate
transitions to the Partial state via agressive link power management nor
the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port
must be programmed to disallow device initiated Partial requests."
Ensure that we always set the corresponding bits in PxSCTL.IPM, such that
a device is not allowed to initiate transitions to power states which are
unsupported by the HBA.
DevSleep is always initiated by the HBA, however, for completeness, set the
corresponding bit in PxSCTL.IPM such that agressive link power management
cannot transition to DevSleep if DevSleep is not supported.
sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp.
However, only libahci has the ability to read the CAP/CAP2 register to see
if these features are supported. Therefore, in order to not introduce any
regressions on ata_piix or libata-pmp, create flags that indicate that the
respective feature is NOT supported. This way, the behavior for ata_piix
and libata-pmp should remain unchanged.
This change is based on a patch originally submitted by Runa Guo-oc.

- remove redundant of_match_ptr()
- stop warning for invalid alarms when the alarm is disabled
Drivers:
- isl12022: allow setting the trip level for battery level detection
- pcf2127: add support for PCF2131 and multiple timestamps
- stm32: time precision improvement, many fixes
- twl: NVRAM support

ARM:
* Clean up vCPU targets, always returning generic v8 as the preferred target
* Trap forwarding infrastructure for nested virtualization (used for traps
that are taken from an L2 guest and are needed by the L1 hypervisor)
* FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
when collapsing a table PTE to a block PTE. This avoids that the guest
refills the TLBs again for addresses that aren't covered by the table PTE.
* Fix vPMU issues related to handling of PMUver.
* Don't unnecessary align non-stack allocations in the EL2 VA space
* Drop HCR_VIRT_EXCP_MASK, which was never used...
* Don't use smp_processor_id() in kvm_arch_vcpu_load(),
but the cpu parameter instead
* Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
* Remove prototypes without implementations
RISC-V:
* Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
* Added ONE_REG interface for SATP mode
* Added ONE_REG interface to enable/disable multiple ISA extensions
* Improved error codes returned by ONE_REG interfaces
* Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
* Added get-reg-list selftest for KVM RISC-V
s390:
* PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
Allows a PV guest to use crypto cards. Card access is governed by
the firmware and once a crypto queue is "bound" to a PV VM every
other entity (PV or not) looses access until it is not bound
anymore. Enablement is done via flags when creating the PV VM.
* Guest debug fixes (Ilya)
x86:
* Clean up KVM's handling of Intel architectural events
* Intel bugfixes
* Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
registers and generate/handle #DBs
* Clean up LBR virtualization code
* Fix a bug where KVM fails to set the target pCPU during an IRTE update
* Fix fatal bugs in SEV-ES intrahost migration
* Fix a bug where the recent (architecturally correct) change to reinject
#BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
* Retry APIC map recalculation if a vCPU is added/enabled
* Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
"emergency disabling" behavior to KVM actually being loaded, and move all of
the logic within KVM
* Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
ratio MSR cannot diverge from the default when TSC scaling is disabled
up related code
* Add a framework to allow "caching" feature flags so that KVM can check if
the guest can use a feature without needing to search guest CPUID
* Rip out the ancient MMU_DEBUG crud and replace the useful bits with
CONFIG_KVM_PROVE_MMU
* Fix KVM's handling of !visible guest roots to avoid premature triple fault
injection
* Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
that is needed by external users (currently only KVMGT), and fix a variety
of issues in the process
This last item had a silly one-character bug in the topic branch that
was sent to me. Because it caused pretty bad selftest failures in
some configurations, I decided to squash in the fix. So, while the
exact commit ids haven't been in linux-next, the code has (from the
kvm-x86 tree).
Generic:
* Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
action specific data without needing to constantly update the main handlers.
* Drop unused function declarations
Selftests:
* Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
* Add support for printf() in guest code and covert all guest asserts to use
printf-based reporting
* Clean up the PMU event filter test and add new testcases
* Include x86 selftests in the KVM x86 MAINTAINERS entry

buffer: Make bh_offset() work for compound pages
If the buffer pointed to by the buffer_head is part of a compound page,
bh_offset() assumes that b_page is the precise page that contains
the data. A recent change to jbd2 inadvertently violated that assumption.
By using page_size(), we support both b_page being set to the head page
(as page_size() will return the size of the entire folio) and the precise
page (as it will return PAGE_SIZE for a tail page).

drm/drm_exec: Work around a WW mutex lockdep oddity
If *any* object of a certain WW mutex class is locked, lockdep will
consider *all* mutexes of that class as locked. Also the lock allocation
tracking code will apparently register only the address of the first
mutex of a given class locked in a sequence.
This has the odd consequence that if that first mutex is unlocked while
other mutexes of the same class remain locked and then its memory then
freed, the lock alloc tracking code will incorrectly assume that memory
is freed with a held lock in there.
For now, work around that for drm_exec by releasing the first grabbed
object lock last.
v2:
- Fix a typo (Danilo Krummrich)
- Reword the commit message a bit.
- Add a Fixes: tag

net: phy: Provide Module 4 KSZ9477 errata (DS80000754C)
The KSZ9477 errata points out (in 'Module 4') the link up/down problems
when EEE (Energy Efficient Ethernet) is enabled in the device to which
the KSZ9477 tries to auto negotiate.
The suggested workaround is to clear advertisement of EEE for PHYs in
this chip driver.
To avoid regressions with other switch ICs the new MICREL_NO_EEE flag
has been introduced.
Moreover, the in-register disablement of MMD_DEVICE_ID_EEE_ADV.MMD_EEE_ADV
MMD register is removed, as this code is both; now executed too late
(after previous rework of the PHY and DSA for KSZ switches) and not
required as setting all members of eee_broken_modes bit field prevents
the KSZ9477 from advertising EEE.

kasan: Add __HAVE_ARCH_SHADOW_MAP to support arch specific mapping
MIPS, LoongArch and some other architectures have many holes between different segments and the valid address space (256T available) is insufficient to map all these segments to kasan shadow memory with the common formula provided by kasan core. So we need architecture specific mapping formulas to ensure different segments are mapped individually, and only limited space lengths of those specific segments are mapped to shadow. Therefore, when the incoming address is converted to a shadow, we need to add a condition to determine whether it is valid.

raid6: Add LoongArch SIMD recovery implementation
Similar to the syndrome calculation, the recovery algorithms also work on 64 bytes at a time to align with the L1 cache line size of current and future LoongArch cores (that we care about). Which means unrolled-by-4 LSX and unrolled-by-2 LASX code. The assembly is originally based on the x86 SSSE3/AVX2 ports, but register allocation has been redone to take advantage of LSX/LASX's 32 vector registers, and instruction sequence has been optimized to suit (e.g. LoongArch can perform per-byte srl and andi on vectors, but x86 cannot). Performance numbers measured by instrumenting the raid6test code, on a 3A5000 system clocked at 2.5GHz: > lasx 2data: 354.987 MiB/s > lasx datap: 350.430 MiB/s > lsx 2data: 340.026 MiB/s > lsx datap: 337.318 MiB/s > intx1 2data: 164.280 MiB/s > intx1 datap: 187.966 MiB/s Because recovery algorithms are chosen solely based on priority and availability, lasx is marked as priority 2 and lsx priority 1. At least for the current generation of LoongArch micro-architectures, LASX should always be faster than LSX whenever supported, and have similar power consumption characteristics (because the only known LASX-capable uarch, the LA464, always compute the full 256-bit result for vector ops).

raid6: Add LoongArch SIMD syndrome calculation
The algorithms work on 64 bytes at a time, which is the L1 cache line size of all current and future LoongArch cores (that we care about), as confirmed by Huacai. The code is based on the generic int.uc algorithm, unrolled 4 times for LSX and 2 times for LASX. Further unrolling does not meaningfully improve the performance according to experiments.

net: team: do not use dynamic lockdep key
team interface has used a dynamic lockdep key to avoid false-positive
lockdep deadlock detection. Virtual interfaces such as team usually
have their own lock for protecting private data.
These interfaces can be nested.
team0
|
team1
Each interface's lock is actually different(team0->lock and team1->lock).
So,
mutex_lock(&team0->lock);
mutex_lock(&team1->lock);
mutex_unlock(&team1->lock);
mutex_unlock(&team0->lock);
The above case is absolutely safe. But lockdep warns about deadlock.
Because the lockdep understands these two locks are same. This is a
false-positive lockdep warning.
So, in order to avoid this problem, the team interfaces started to use
dynamic lockdep key. The false-positive problem was fixed, but it
introduced a new problem.
When the new team virtual interface is created, it registers a dynamic
lockdep key(creates dynamic lockdep key) and uses it. But there is the
limitation of the number of lockdep keys.
So, If so many team interfaces are created, it consumes all lockdep keys.
Then, the lockdep stops to work and warns about it.
In order to fix this problem, team interfaces use the subclass instead
of the dynamic key. So, when a new team interface is created, it doesn't
register(create) a new lockdep, but uses existed subclass key instead.
It is already used by the bonding interface for a similar case.
As the bonding interface does, the subclass variable is the same as
the 'dev->nested_level'. This variable indicates the depth in the stacked
interface graph.
The 'dev->nested_level' is protected by RTNL and RCU.
So, 'mutex_lock_nested()' for 'team->lock' requires RTNL or RCU.
In the current code, 'team->lock' is usually acquired under RTNL, there is
no problem with using 'dev->nested_level'.
The 'team_nl_team_get()' and The 'lb_stats_refresh()' functions acquire
'team->lock' without RTNL.
But these don't iterate their own ports nested so they don't need nested
lock.
Reproducer:
for i in {0..1000}
do
ip link add team$i type team
ip link add dummy$i master team$i type dummy
ip link set dummy$i up
ip link set team$i up
done
Splat looks like:
BUG: MAX_LOCKDEP_ENTRIES too low!
turning off the locking correctness validator.

xarray: Document necessary flag in alloc functions
Adds a new line to the docstrings of functions wrapping __xa_alloc() and __xa_alloc_cyclic(), informing about the necessity of flag XA_FLAGS_ALLOC being set previously. The documentation so far says that functions wrapping __xa_alloc() and __xa_alloc_cyclic() are supposed to return either -ENOMEM or -EBUSY in case of an error. If the xarray has been initialized without the flag XA_FLAGS_ALLOC, however, they fail with a different, undocumented error code. As hinted at in Documentation/core-api/xarray.rst, wrappers around these functions should only be invoked when the flag has been set. The functions' documentation should reflect that as well.

scsi: qla2xxx: Correct endianness for rqstlen and rsplen
rqstlen and rsplen were changed to __le32 to fix sparse warnings:
drivers/scsi/qla2xxx/qla_nvme.c:402:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:402:30: expected restricted __le32 [usertype] cmd_len
drivers/scsi/qla2xxx/qla_nvme.c:402:30: got unsigned short [usertype] rsplen
drivers/scsi/qla2xxx/qla_nvme.c:507:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:507:30: expected restricted __le32 [usertype] cmd_len
drivers/scsi/qla2xxx/qla_nvme.c:507:30: got unsigned int [usertype] rqstlen
drivers/scsi/qla2xxx/qla_nvme.c:508:30: warning: incorrect type in assignment (different base types)
drivers/scsi/qla2xxx/qla_nvme.c:508:30: expected restricted __le32 [usertype] rsp_len
drivers/scsi/qla2xxx/qla_nvme.c:508:30: got unsigned int [usertype] rsplen
Correct the endianness in qla2xxx driver thus avoiding changes in
nvme-fc-driver.h.
