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.

This patch fixes above issue in branch_stack__printf(). For example,

	# echo 'scale=2000; 4*a(1)' > cmd
	# perf record --call-graph lbr bc -l < cmd

Perf BPF filter test fails in environment where "clang" is not
installed.

Test failure logs:

<<>>
 42: BPF filter                    :
 42.1: Basic BPF filtering         : Skip
 42.2: BPF pinning                 : FAILED!
 42.3: BPF prologue generation     : FAILED!
<<>>

Enabling verbose option provided debug logs which says clang/llvm needs
to be installed. Snippet of verbose logs:

<<>>
 42.2: BPF pinning                  :
 --- start ---
test child forked, pid 61423
ERROR:	unable to find clang.
Hint:	Try to install latest clang/llvm to support BPF.
        Check your $PATH

<<logs_here>>

Failed to compile test case: 'Basic BPF llvm compile'
Unable to get BPF object, fix kbuild first
test child finished with -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:

<<>>
 42: BPF filter                    :
 42.1: Basic BPF filtering         : Skip
 42.2: BPF pinning                 : Skip
 42.3: BPF prologue generation     : Skip

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.

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.

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 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.

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.

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.

In kvm_hv_flush_tlb(), valid_bank_mask is declared as unsigned long,
but is used as u64, which is wrong for i386, and has been spotted by
LKP after applying "KVM: x86: hyper-v: replace bitmap_weight() with
hweight64()"

https://lore.kernel.org/lkml/20220510154750.212913-12-yury.norov@gmail.com/

But it's wrong even without that patch because now bitmap_weight()
dereferences a word after valid_bank_mask on i386.

Fix a goof in kvm_prepare_memory_region() where KVM fails to free the
new memslot's dirty bitmap during a CREATE action if
kvm_arch_prepare_memory_region() fails.  The logic is supposed to detect
if the bitmap was allocated and thus needs to be freed, versus if the
bitmap was inherited from the old memslot and thus needs to be kept.  If
there is no old memslot, then obviously the bitmap can't have been
inherited

The bug was exposed by commit 86931ff7 ("KVM: x86/mmu: Do not create
SPTEs for GFNs that exceed host.MAXPHYADDR"), which made it trivally easy
for syzkaller to trigger failure during kvm_arch_prepare_memory_region(),
but the bug can be hit other ways too, e.g. due to -ENOMEM when
allocating x86's memslot metadata.

Avi Kivity reported a problem where the __weak
btf__load_from_kernel_by_id() in tools/perf/util/bpf-event.c was being
used and it called btf__get_from_id() in tools/lib/bpf/btf.c that in
turn called back to btf__load_from_kernel_by_id(), resulting in an
endless loop.

Fix this by adding a feature test to check if
btf__load_from_kernel_by_id() is available when building perf with
LIBBPF_DYNAMIC=1, and if not then provide the fallback to the old
btf__get_from_id(), that doesn't call back to btf__load_from_kernel_by_id()
since at that time it didn't exist at all.

Tested on Fedora 35 where we have libbpf-devel 0.4.0 with LIBBPF_DYNAMIC
where we don't have btf__load_from_kernel_by_id() and thus its feature
test fail, not defining HAVE_LIBBPF_BTF__LOAD_FROM_KERNEL_BY_ID:

Add a test to demonstrate that when the guest programs an event select
it is matched correctly in the pmu event filter and not inadvertently
filtered.  This could happen on AMD if the high nybble[1] in the event
select gets truncated away only leaving the bottom byte[2] left for
matching.

This is a contrived example used for the convenience of demonstrating
this issue, however, this can be applied to event selects 0x28A (OC
Mode Switch) and 0x08A (L1 BTB Correction), where 0x08A could end up
being denied when the event select was only set up to deny 0x28A.

 "We had two big outstanding issues after v5.18-rc6:

   a) 32-bit kernels on 64-bit machines (e.g. on a C3700 which is able
      to run 32- and 64-bit kernels) failed early in userspace.

   b) 64-bit kernels on PA8800/PA8900 CPUs (e.g. in a C8000) showed
      random userspace segfaults. We assumed that those problems were
      caused by the tmpalias flushes.

  Dave did a lot of testing and reorganization of the current flush code
  and fixed the 32-bit cache flushing. For PA8800/PA8900 CPUs he
  switched the code to flush using the virtual address of user and
  kernel pages instead of using tmpalias flushes. The tmpalias flushes
  don't seem to work reliable on such CPUs.

  We tested the patches on a wide range machines (715/64, B160L, C3000,
  C3700, C8000, rp3440) and they have been in for-next without any
  conflicts.

  Summary:

   - Rewrite the cache flush code for PA8800/PA8900 CPUs to flush using
     the virtual address of user and kernel pages instead of using
     tmpalias flushes. Testing showed, that tmpalias flushes don't work
     reliably on PA8800/PA8900 CPUs

   - Fix flush code to allow 32-bit kernels to run on 64-bit capable
     machines, e.g. a 32-bit kernel on C3700 machines"

 "Including fixes from can, xfrm and netfilter subtrees.

  Notably this reverts a recent TCP/DCCP netns-related change to address
  a possible UaF.

  Current release - regressions:

   - tcp: revert "tcp/dccp: get rid of inet_twsk_purge()"

   - xfrm: set dst dev to blackhole_netdev instead of loopback_dev in
     ifdown

  Previous releases - regressions:

   - netfilter: flowtable: fix TCP flow teardown

   - can: revert "can: m_can: pci: use custom bit timings for Elkhart
     Lake"

   - xfrm: check encryption module availability consistency

   - eth: vmxnet3: fix possible use-after-free bugs in
     vmxnet3_rq_alloc_rx_buf()

   - eth: mlx5: initialize flow steering during driver probe

   - eth: ice: fix crash when writing timestamp on RX rings

  Previous releases - always broken:

   - mptcp: fix checksum byte order

   - eth: lan966x: fix assignment of the MAC address

   - eth: mlx5: remove HW-GRO from reported features

   - eth: ftgmac100: disable hardware checksum on AST2600"
