This patch updated the output info of chk_rm_nr. Renamed 'sf' to 'rmsf',
which means 'remove subflow'. Added the display of whether the inverted
namespaces has been used to check the mib counters.
The new output looks like this:
002 remove multiple subflows syn[ ok ] - synack[ ok ] - ack[ ok ]
rm [ ok ] - rmsf [ ok ]
003 remove single address syn[ ok ] - synack[ ok ] - ack[ ok ]
add[ ok ] - echo [ ok ]
rm [ ok ] - rmsf [ ok ] invert

This patch added five more arguments for chk_join_nr(). The default
values of them are all zero.
The first two, csum_ns1 and csum_ns1, are passed to chk_csum_nr(), to
check the mib counters of the checksum errors in ns1 and ns2. A '+'
can be added into this two arguments to represent that multiple
checksum errors are allowed when doing this check. For example,
chk_csum_nr "" +2 +2
indicates that two or more checksum errors are allowed in both ns1 and
ns2.
The remaining two, fail_nr and rst_nr, are passed to chk_fail_nr() and
chk_rst_nr() respectively, to check the sending and receiving mib
counters of MP_FAIL and MP_RST.
Also did some cleanups in chk_fail_nr(), renamed two local variables
and updated the output message.

This patch added the invert bytes check for the output data in
check_transfer().
Instead of the file mismatch error:

-rw------- 1 root root 45643832 Jan 16 15:04 /tmp/tmp.wnz1Yp4u7Z
Trailing bytes are:

This patch added the self test for MP_FASTCLOSE. Reused the argument
addr_nr_ns2 of do_transfer() to pass the extra arguments '-I 2' to
mptcp_connect commands. Then mptcp_connect disconnected the
connections to trigger the MP_FASTCLOSE sending and receiving. Used
chk_fclose_nr to check the MP_FASTCLOSE mibs and used chk_rst_nr to
check the MP_RST mibs. This test used the test_linkfail value to make
1024KB test files.
The output looks like this:
Created /tmp/tmp.XB8sfv1hJ0 (size 1024 KB) containing data sent by client
Created /tmp/tmp.RtTDbzqrXI (size 1024 KB) containing data sent by server

Instead of using a global variable mptcp_connect, this patch added

pull-request: bpf-next 2022-03-04
We've added 32 non-merge commits during the last 14 day(s) which contain
a total of 59 files changed, 1038 insertions(+), 473 deletions(-).
The main changes are:
1) Optimize BPF stackmap's build_id retrieval by caching last valid build_id,
as consecutive stack frames are likely to be in the same VMA and therefore
have the same build id, from Hao Luo.
2) Several improvements to arm64 BPF JIT, that is, support for JITing
the atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and lastly
atomic[64]_{xchg|cmpxchg}. Also fix the BTF line info dump for JITed
programs, from Hou Tao.
3) Optimize generic BPF map batch deletion by only enforcing synchronize_rcu()
barrier once upon return to user space, from Eric Dumazet.
4) For kernel build parse DWARF and generate BTF through pahole with enabled
multithreading, from Kui-Feng Lee.
5) BPF verifier usability improvements by making log info more concise and
replacing inv with scalar type name, from Mykola Lysenko.
6) Two follow-up fixes for BPF prog JIT pack allocator, from Song Liu.
7) Add a new Kconfig to allow for loading kernel modules with non-matching
BTF type info; their BTF info is then removed on load, from Connor O'Brien.
8) Remove reallocarray() usage from bpftool and switch to libbpf_reallocarray()
in order to fix compilation errors for older glibc, from Mauricio Vásquez.
9) Fix libbpf to error on conflicting name in BTF when type declaration
appears before the definition, from Xu Kuohai.
10) Fix issue in BPF preload for in-kernel light skeleton where loaded BPF
program fds prevent init process from setting up fd 0-2, from Yucong Sun.
11) Fix libbpf reuse of pinned perf RB map when max_entries is auto-determined
by libbpf, from Stijn Tintel.
12) Several cleanups for libbpf and a fix to enforce perf RB map #pages to be
non-zero, from Yuntao Wang.

"Including fixes from can, xfrm, wifi, bluetooth, and netfilter.
Lots of various size fixes, the length of the tag speaks for itself.
Most of the 5.17-relevant stuff comes from xfrm, wifi and bt trees

The test runs several test cases and is supposed to return an error in
case at least one of them failed.
Currently, the check of the return value of each test case is in the
wrong place, which can result in the wrong return value. For example:
# TESTS='tc_police' ./resource_scale.sh
TEST: 'tc_police' [default] 968 [FAIL]
tc police offload count failed
Error: mlxsw_spectrum: Failed to allocate policer index.
We have an error talking to the kernel
Command failed /tmp/tmp.i7Oc5HwmXY:969
TEST: 'tc_police' [default] overflow 969 [ OK ]
...
TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ]
$ echo $?
0
Fix this by moving the check to be done after each test case.

iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control

following output:

The current grep expression matches on both 'in_hw' and 'not_in_hw',

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"The bigger part of the change is a revert for x86 hosts. Here the
second patch was supposed to fix the first, but in reality it was just
as broken, so both have to go.
x86 host:
- Revert incorrect assumption that cr3 changes come with preempt
notifier callbacks (they don't when static branches are changed,
for example)
ARM host:
- Correctly synchronise PMR and co on PSCI CPU_SUSPEND
- Skip tests that depend on GICv3 when the HW isn't available"
* tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm:
KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3
Revert "KVM: VMX: Save HOST_CR3 in vmx_prepare_switch_to_guest()"
Revert "KVM: VMX: Save HOST_CR3 in vmx_set_host_fs_gs()"
KVM: arm64: Don't miss pending interrupts for suspended vCPU
The main thing that the selftest verifies is that KVM copies x2APIC's
ICR[63:32] to/from ICR2 when userspace accesses the vAPIC page via
KVM_{G,S}ET_LAPIC. KVM previously split x2APIC ICR to ICR+ICR2 at the
time of write (from the guest), and so KVM must preserve that behavior
for backwards compatibility between different versions of KVM.
It will also test other invariants, e.g. that KVM clears the BUSY
flag on ICR writes, that the reserved bits in ICR2 are dropped on writes
from the guest, etc...

The testcase uses event code 0x500fa ("instructions") to check the
CC56RUN bit setting in Monitor Mode Control Register 0(MMCR0). In ISA
v3.1 platform, this bit is expected to be set in MMCR0 when using
Performance Monitor Counter 5 and 6 (PMC5 and PMC6). Verify this is done
correctly by perf interface.
CC56RUN bit makes PMC5 and PMC6 count regardless of the run latch state.
This bit is set in power10 since PMC5 and PMC6 is used in power10 for
counting instructions and cycles. Hence added a check to skip this test
in other platforms

The testcase uses "instructions" event to verify two bits(PMAE and PMAO)
in Monitor Mode Control Register 0 (MMCR0). At the time of interrupt,
pmae bit ( which enables performance monitor exception ) is expected to

expected to be set in MMCR0. And testcases handles these checks.
