Updates for interrupt core and drivers:
Core code:
- Make the managed interrupts more robust by shutting them down in the
core code when the assigned affinity mask does not contain online
CPUs.
- Make the irq simulator chip work on RT
- A small set of cpumask and power manageent cleanups
Drivers:
- A set of changes which mark GPIO interrupt chips immutable to prevent
the GPIO subsystem from modifying it under the hood. This provides
the necessary infrastructure and converts a set of GPIO and pinctrl
drivers over.
- A set of changes to make the pseudo-NMI handling for GICv3 more
robust: a missing barrier and consistent handling of the priority
mask.
- Another set of GICv3 improvements and fixes, but nothing outstanding
- The usual set of improvements and cleanups all over the place
- No new irqchip drivers and not even a new device tree binding!
100+ interrupt chips are truly enough.

Updates for CPU hotplug:
- Initialize the per CPU structures during early boot so that the state
is consistent from the very beginning.
- Make the virtualization hotplug state handling more robust and let the
core bringup CPUs which timed out in an earlier attempt again.
- Make the x86/XEN CPU state tracking consistent on a failed online
attempt, so a consecutive bringup does not fall over the inconsistent
state.

A single update for irqpoll:
- Ensure that a raised soft interrupt is handled after pulling the
blk_cpu_iopoll backlog from a unplugged CPU. This prevents that the CPU
which runs that code reaches idle with soft interrupts pending.

afs: Fix afs_getattr() to refetch file status if callback break occurred
If a callback break occurs (change notification), afs_getattr() needs to
issue an FS.FetchStatus RPC operation to update the status of the file
being examined by the stat-family of system calls.
Fix afs_getattr() to do this if AFS_VNODE_CB_PROMISED has been cleared
on a vnode by a callback break. Skip this if AT_STATX_DONT_SYNC is set.
This can be tested by appending to a file on one AFS client and then
using "stat -L" to examine its length on a machine running kafs. This
can also be watched through tracing on the kafs machine. The callback
break is seen:
kworker/1:1-46 [001] ..... 978.910812: afs_cb_call: c=0000005f YFSCB.CallBack
kworker/1:1-46 [001] ...1. 978.910829: afs_cb_break: 100058:23b4c:242d2c2 b=2 s=1 break-cb
kworker/1:1-46 [001] ..... 978.911062: afs_call_done: c=0000005f ret=0 ab=0 [0000000082994ead]
And then the stat command generated no traffic if unpatched, but with
this change a call to fetch the status can be observed:
stat-4471 [000] ..... 986.744122: afs_make_fs_call: c=000000ab 100058:023b4c:242d2c2 YFS.FetchStatus
stat-4471 [000] ..... 986.745578: afs_call_done: c=000000ab ret=0 ab=0 [0000000087fc8c84]

perf session: Fix Intel LBR callstack entries and nr print message
When generating callstack information from branch_stack(Intel LBR), the actual number of callstack entry should be bigger than the number of branch_stack, for example: branch_stack records: B() -> C() A() -> B() converted callstack records should be: C() B() A() though, the number of callstack equals to the number of branch stack plus 1.

---- end ----
BPF filter subtest 2: FAILED!
<<>>
Here subtests, "BPF pinning" and "BPF prologue generation" failed and
logs shows clang/llvm is needed. After installing clang, testcase
passes.
Reason on why subtest failure happens though logs has proper debug
information:
Main function __test__bpf calls test_llvm__fetch_bpf_obj by
passing 4th argument as true ( 4th arguments maps to parameter
"force" in test_llvm__fetch_bpf_obj ). But this will cause
test_llvm__fetch_bpf_obj to skip the check for clang/llvm.
Snippet of code part which checks for clang based on
parameter "force" in test_llvm__fetch_bpf_obj:
<<>>
if (!force && (!llvm_param.user_set_param &&
<<>>
Since force is set to "false", test won't get skipped and fails to
compile test case. The BPF code compilation needs clang, So pass the
fourth argument as "false" and also skip the test if reason for return
is "TEST_SKIP"
After the patch:

perf test session topology: Fix test to skip the test in guest environment
The session topology test fails in powerpc pSeries platform. Test logs: <<>> Session topology : FAILED! <<>> This testcases tests cpu topology by checking the core_id and socket_id stored in perf_env from perf session. The data from perf session is compared with the cpu topology information from "/sys/devices/system/cpu/cpuX/topology" like core_id, physical_package_id. In case of virtual environment, detail like physical_package_id is restricted to be exposed. Hence physical_package_id is set to -1. The testcase fails on such platforms since socket_id can't be fetched from topology info. Skip the testcase in powerpc if physical_package_id returns -1.

perf test: Avoid shell test description infinite loop
for_each_shell_test() is already strict in expecting tests to be files and executable. It is sometimes possible when it iterates over all files that it finds one that is executable and lacks a newline character. When this happens the loop never terminates as it doesn't check for EOF. Add the EOF check to make this loop at least bounded by the file size. If the description is returned as NULL then also skip the test.

perf regs x86: Fix arch__intr_reg_mask() for the hybrid platform
The X86 specific arch__intr_reg_mask() is to check whether the kernel
and hardware can collect XMM registers. But it doesn't work on some
hybrid platform.
Without the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15
The config of the test event doesn't contain the PMU information. The
kernel may fail to initialize it on the correct hybrid PMU and return
the wrong non-supported information.
Add the PMU information into the config for the hybrid platform. The
same register set is supported among different hybrid PMUs. Checking
the first available one is good enough.
With the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15 XMM0 XMM1 XMM2 XMM3 XMM4 XMM5 XMM6 XMM7 XMM8 XMM9

perf test: Fix "all PMU test" to skip hv_24x7/hv_gpci tests on powerpc
"perf all PMU test" picks the input events from "perf list --raw-dump
pmu" list and runs "perf stat -e" for each of the event in the list. In
case of powerpc, the PowerVM environment supports events from hv_24x7
and hv_gpci PMU which is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/
The value for "?" needs to be filled in depending on system and
respective event. CPM_ADJUNCT_INST needs have core value and domain
value. hv_gpci event needs partition_id. Similarly, there are other
events for hv_24x7 and hv_gpci having "?" in event format. Hence skip
these events on powerpc platform since values like partition_id, domain
is specific to system and event.

io_uring: cleanup handling of the two task_work lists
Rather than pass in a bool for whether or not this work item needs to go into the priority list or not, provide separate helpers for it. For most use cases, this also then gets rid of the branch for non-priority task work. While at it, rename the prior_task_list to prio_task_list. Prior is a confusing name for it, as it would seem to indicate that this is the previous task_work list. prio makes it clear that this is a priority task_work list.

i2c: ismt: Provide a DMA buffer for Interrupt Cause Logging
Before sending a MSI the hardware writes information pertinent to the
interrupt cause to a memory location pointed by SMTICL register. This
memory holds three double words where the least significant bit tells
whether the interrupt cause of master/target/error is valid. The driver
does not use this but we need to set it up because otherwise it will
perform DMA write to the default address (0) and this will cause an
IOMMU fault such as below:
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0
[fault reason 05] PTE Write access is not set
To prevent this from happening, provide a proper DMA buffer for this
that then gets mapped by the IOMMU accordingly.

* Don't issue a hypercall to set the id-mapped vectors when
protected mode is enabled (fix for pKVM in combination with
CPUs affected by Spectre-v3a)
x86: Five oneliners, of which the most interesting two are:
* a NULL pointer dereference on INVPCID executed with
paging disabled, but only if KVM is using shadow paging
* an incorrect bsearch comparison function which could truncate
the result and apply PMU event filtering incorrectly. This one
comes with a selftests update too.

perf: Fix sys_perf_event_open() race against self
Norbert reported that it's possible to race sys_perf_event_open() such
that the looser ends up in another context from the group leader,
triggering many WARNs.
The move_group case checks for races against itself, but the
!move_group case doesn't, seemingly relying on the previous
group_leader->ctx == ctx check. However, that check is racy due to not
holding any locks at that time.
Therefore, re-check the result after acquiring locks and bailing
if they no longer match.
Additionally, clarify the not_move_group case from the
move_group-vs-move_group race.

KVM: x86/mmu: fix NULL pointer dereference on guest INVPCID
With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference. Fix it trivially by checking for mmu->invlpg before every call. There are other possibilities: - check for CR0.PG, because KVM (like all Intel processors after P5) flushes guest TLB on CR0.PG changes so that INVPCID/INVLPG are a nop with paging disabled - check for EFER.LMA, because KVM syncs and flushes when switching MMU contexts outside of 64-bit mode All of these are tricky, go for the simple solution. This is CVE-2022-1789. Reported-by: Yongkang Jia <kangel@zju.edu.cn> Cc: stable@vger.kernel.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |
