Pull kvm updates from Paolo Bonzini:
"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
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"

enetc_psi_create() returns an ERR_PTR() or a valid station interface
pointer, but checking for the non-NULL quality of the return code blurs
that difference away. So if enetc_psi_create() fails, we call
enetc_psi_destroy() when we shouldn't. This will likely result in
crashes, since enetc_psi_create() cleans up everything after itself when
it returns an ERR_PTR().

Pull more s390 updates from Heiko Carstens:
- A couple of virtual vs physical address confusion fixes
- Rework locking in dcssblk driver to address a lockdep warning
- Remove support for "noexec" kernel command line option since there is
no use case where it would make sense
- Simplify kernel mapping setup and get rid of quite a bit of code
- Add architecture specific __set_memory_yy() functions which allow us
to modify kernel mappings. Unlike the set_memory_xx() variants they
take void pointer start and end parameters, which allows using them
without the usual casts, and also to use them on areas larger than
8TB.
Note that the set_memory_xx() family comes with an int num_pages
parameter which overflows with 8TB. This could be addressed by
changing the num_pages parameter to unsigned long, however requires
to change all architectures, since the module code expects an int
parameter (see module_set_memory()).
This was indeed an issue since for debug_pagealloc() we call
set_memory_4k() on the whole identity mapping. Therefore address this
for now with the __set_memory_yy() variant, and address common code
later

Commit 254986e324ad ("drm/radeon: Use the drm suballocation manager implementation.")
made the fence wait in amdgpu_sa_bo_new() interruptible but there is no
code to handle an interrupt. This caused the kernel to randomly explode
in high-VRAM-pressure situations so make it uninterruptible again.

We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.
However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.
This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE
at the hclge layer,

Currently, the driver knocks the ring doorbell before updating
the ring->last_to_use in tx flow. if the hardware transmiting
packet and napi poll scheduling are fast enough, it may get
the old ring->last_to_use in drivers' napi poll.
In this case, the driver will think the tx is not completed, and
return directly without clear the flag __QUEUE_STATE_STACK_XOFF,
which may cause tx timeout.

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.

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.

For DRM legacy gamma, AMD display manager applies implicit sRGB degamma
using a pre-defined sRGB transfer function. It works fine for DCN2
family where degamma ROM and custom curves go to the same color block.
But, on DCN3+, degamma is split into two blocks: degamma ROM for
pre-defined TFs and `gamma correction` for user/custom curves and
degamma ROM settings doesn't apply to cursor plane. To get DRM legacy
gamma working as expected, enable cursor degamma ROM for implict sRGB
degamma on HW with this configuration.

Since, calling dcn20_adjust_freesync_v_startup() on DCN3.1+ ASICs
can cause the display to flicker and underflow to occur, we shouldn't
call it for them. So, ensure that the DCN version is less than
DCN_VERSION_3_1 before calling dcn20_adjust_freesync_v_startup().

System runs at minimum performance, once powercap RAPL package domain
enabled flag is changed from 1 to 0 to 1.
Setting RAPL package domain enabled flag to 0, results in setting of
power limit 4 (PL4) MSR 0x601 to 0. This implies disabling PL4 limit.
The PL4 limit controls the peak power. So setting 0, results in some
undesirable performance, which depends on hardware implementation.
Even worse, when the enabled flag is set to 1 again. This will set PL4
MSR value to 0x01, which means reduce peak power to 0.125W. This will
force system to run at the lowest possible performance on every PL4
supported system.
Setting enabled flag should only affect the "enable" bit, not other
bits. Here it is changing power limit.
This is caused by a change which assumes that there is an enable bit in
the PL4 MSR like other power limits. Although PL4 enable/disable bit is
present with TPMI RAPL interface, it is not present with the MSR
interface.
There is a rapl_primitive_info defined for non existent PL4 enable bit
and then it is used with the commit 9050a9cd5e4c ("powercap: intel_rapl:
Cleanup Power Limits support") to enable PL4. This is wrong, hence remove
this rapl primitive for PL4. Also in the function
rapl_detect_powerlimit(), PL_ENABLE is used to check for the presence of
power limits. Replace PL_ENABLE with PL_LIMIT, as PL_LIMIT must be
present. Without this change, PL4 controls will not be available in the
sysfs once rapl primitive for PL4 is removed.

bvec_set_page has the following signature:
static inline void bvec_set_page(struct bio_vec *bv, struct page *page,
unsigned int len, unsigned int offset)
However, the usage in DRBD swaps the len and offset parameters. This
leads to a bvec with length=0 instead of the intended length=4096, which
causes sock_sendmsg to return -EIO.
This leaves DRBD unable to transmit any pages and thus completely
broken.
Swapping the parameters fixes the regression.

The blamed commit left this delta behind:
struct sja1105_cbs_entry {
- u64 port;
- u64 prio;
+ u64 port; /* Not used for SJA1110 */
+ u64 prio; /* Not used for SJA1110 */
u64 credit_hi;
u64 credit_lo;
u64 send_slope;
u64 idle_slope;
};
but did not actually implement tc-cbs offload fully for the new switch.
The offload is accepted, but it doesn't work.
The difference compared to earlier switch generations is that now, the
table of CBS shapers is sparse, because there are many more shapers, so
the mapping between a {port, prio} and a table index is static, rather
than requiring us to store the port and prio into the sja1105_cbs_entry.
So, the problem is that the code programs the CBS shaper parameters at a
dynamic table index which is incorrect.
All that needs to be done for SJA1110 CBS shapers to work is to bypass
the logic which allocates shapers in a dense manner, as for SJA1105, and
use the fixed mapping instead.

we start seeing the following error message:
Error: Specified device failed to setup cbs hardware offload.
This comes from the fact that ndo_setup_tc(TC_SETUP_QDISC_CBS) presents
the same API for the qdisc create and replace cases, and the sja1105
driver fails to distinguish between the 2. Thus, it always thinks that
it must allocate the same shaper for a {port, queue} pair, when it may
instead have to replace an existing one.

More careful measurement of the tc-cbs bandwidth shows that the stream
bandwidth (effectively idleslope) increases, there is a larger and
larger discrepancy between the rate limit obtained by the software
Qdisc, and the rate limit obtained by its offloaded counterpart.
The discrepancy becomes so large, that e.g. at an idleslope of 40000
(40Mbps), the offloaded cbs does not actually rate limit anything, and
traffic will pass at line rate through a 100 Mbps port.
The reason for the discrepancy is that the hardware documentation I've
been following is incorrect. UM11040.pdf (for SJA1105P/Q/R/S) states
about IDLE_SLOPE that it is "the rate (in unit of bytes/sec) at which
the credit counter is increased".
Cross-checking with UM10944.pdf (for SJA1105E/T) and UM11107.pdf
(for SJA1110), the wording is different: "This field specifies the
value, in bytes per second times link speed, by which the credit counter
is increased".
So there's an extra scaling for link speed that the driver is currently
not accounting for, and apparently (empirically), that link speed is
expressed in Kbps.
I've pondered whether to pollute the sja1105_mac_link_up()
implementation with CBS shaper reprogramming, but I don't think it is
worth it. IMO, the UAPI exposed by tc-cbs requires user space to
recalculate the sendslope anyway, since the formula for that depends on
port_transmit_rate (see man tc-cbs), which is not an invariant from tc's
perspective.
So we use the offload->sendslope and offload->idleslope to deduce the
original port_transmit_rate from the CBS formula, and use that value to
scale the offload->sendslope and offload->idleslope to values that the
hardware understands.

ACL flow table is required in switchdev mode when metadata is enabled,
driver creates such table when loading each vport. However, not every
vport is loaded in switchdev mode. Such as ECPF if it's the eswitch manager.
In this case, ACL flow table is still needed.
To make it modularized, create ACL flow table for eswitch manager as
default and skip such operations when loading manager vport.
Also, there is no need to load the eswitch manager vport in switchdev mode.
This means there is no need to load it on regular connect-x HCAs where
the PF is the eswitch manager. This will avoid creating duplicate ACL
flow table for host PF vport.

In the cited commit, the mirred devices are recorded and checked while
parsing the actions. In order to avoid system crash, the duplicate
action in a single rule is not allowed.
But the rule is actually break down into several FTEs in different
tables, for either mirroring, or the specified types of actions which
use post action infrastructure.
It will reject certain action list by mistake, for example:
actions:enp8s0f0_1,set(ipv4(ttl=63)),enp8s0f0_0,enp8s0f0_1.
Here the rule is split to two FTEs because of pedit action.
To fix this issue, when parsing the rule actions, reset if_count to
clear the mirred devices array if the rule is split to multiple
FTEs, and then the duplicate checking is restarted.

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

When the alarm is not enabled, it may never have been set and so we can't
expect it to be valid. This will prevent the apparition of boot messages
like this one:
rtc rtc0: invalid alarm value: 2023-7-8 45:85:85

I3C masters are expected to support hot-join. This means at initialization
time we might not yet discover any device and this should not be treated
as a fatal error.
During the DAA procedure which happens at probe time, if no device has
joined, all CCC will be NACKed (from a bus perspective). This leads to an
early return with an error code which fails the probe of the master.
Let's avoid this by just telling the core through an I3C_ERROR_M2
return command code that no device was discovered, which is a valid
situation. This way the master will no longer bail out and fail to probe
for a wrong reason.
