Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next. This
includes one patch to update ovs and act_ct to use nf_ct_put() instead
of nf_conntrack_put().
1) Add netns_tracker to nfnetlink_log and masquerade, from Eric Dumazet.
2) Remove redundant rcu read-size lock in nf_tables packet path.
3) Replace BUG() by WARN_ON_ONCE() in nft_payload.
4) Consolidate rule verdict tracing.
5) Replace WARN_ON() by WARN_ON_ONCE() in nf_tables core.
6) Make counter support built-in in nf_tables.
7) Add new field to conntrack object to identify locally generated
traffic, from Florian Westphal.
8) Prevent NAT from shadowing well-known ports, from Florian Westphal.
9) Merge nf_flow_table_{ipv4,ipv6} into nf_flow_table_inet, also from
Florian.
10) Remove redundant pointer in nft_pipapo AVX2 support, from Colin Ian King.
11) Replace opencoded max() in conntrack, from Jiapeng Chong.
12) Update conntrack to use refcount_t API, from Florian Westphal.
13) Move ip_ct_attach indirection into the nf_ct_hook structure.
14) Constify several pointer object in the netfilter codebase,
from Florian Westphal.
15) Tree-wide replacement of nf_conntrack_put() by nf_ct_put(), also
from Florian.
16) Fix egress splat due to incorrect rcu notation, from Florian.
17) Move stateful fields of connlimit, last, quota, numgen and limit
out of the expression data area.
18) Build a blob to represent the ruleset in nf_tables, this is a
requirement of the new register tracking infrastructure.
19) Add NFT_REG32_NUM to define the maximum number of 32-bit registers.
20) Add register tracking infrastructure to skip redundant
store-to-register operations, this includes support for payload,
meta and bitwise expresssions.

MPTCP join self-tests are a bit fragile as they reply on
delays instead of events to catch-up with the expected
sockets states.
Replace the delay with state checking where possible and
reduce the number of sleeps in the most complex scenarios.
This will both reduce the tests run-time and will improve
stability.

Now that core kvm_util declarations have special home in
kvm_util_base.h, move ucall-related declarations out into a separate
header.

Between helper macros and interfaces that will be introduced in
subsequent patches, much of kvm_util.h would end up being declarations
specific to ucall. Ideally these could be separated out into a separate
header since they are not strictly required for writing guest tests and
are mostly self-contained interfaces other than a reliance on a few
core declarations like struct kvm_vm. This doesn't make a big
difference as far as how tests will be compiled/written since all these
interfaces will still be packaged up into a single/common libkvm.a used
by all tests, but it is still nice to be able to compartmentalize to
improve readabilty and reduce merge conflicts in the future for common
tasks like adding new interfaces to kvm_util.h.
Furthermore, some of the ucall declarations will be arch-specific,
requiring various #ifdef'ery in kvm_util.h. Ideally these declarations
could live in separate arch-specific headers, e.g.
include/<arch>/ucall.h, which would handle arch-specific declarations
as well as pulling in common ucall-related declarations shared by all
archs.
One simple way to do this would be to #include ucall.h at the bottom of
kvm_util.h, after declarations it relies upon like struct kvm_vm.
This is brittle however, and doesn't scale easily to other sets of
interfaces that may be added in the future.
Instead, move all declarations currently in kvm_util.h into
kvm_util_base.h, then have kvm_util.h #include it. With this change,
non-base declarations can be selectively moved/introduced into separate
headers, which can then be included in kvm_util.h so that individual
tests don't need to be touched. Subsequent patches will then move
ucall-related declarations into a separate header to meet the above
goals.

This adds basic support for delivering 2 level event channels to a guest.
Initially, it only supports delivery via the IRQ routing table, triggered
by an eventfd. In order to do so, it has a kvm_xen_set_evtchn_fast()
function which will use the pre-mapped shared_info page if it already
exists and is still valid, while the slow path through the irqfd_inject
workqueue will remap the shared_info page if necessary.
It sets the bits in the shared_info page but not the vcpu_info; that is
deferred to __kvm_xen_has_interrupt() which raises the vector to the
appropriate vCPU.
Add a 'verbose' mode to xen_shinfo_test while adding test cases for this.

TEST_ASSERT in SEV ioctl was allowing errors because it checked return
value was good OR the FW error code was OK. This TEST_ASSERT should
require both (aka. AND) values are OK. Removes the LAUNCH_START from the
mirror VM because this call correctly fails because mirror VMs cannot
call this command. Currently issues with the PSP driver functions mean
the firmware error is not always reset to SEV_RET_SUCCESS when a call is
successful. Mainly sev_platform_init() doesn't correctly set the fw
error if the platform has already been initialized.

KVM/arm64 updates for Linux 5.16
- Simplification of the 'vcpu first run' by integrating it into
KVM's 'pid change' flow
- Refactoring of the FP and SVE state tracking, also leading to
a simpler state and less shared data between EL1 and EL2 in
the nVHE case
- Tidy up the header file usage for the nvhe hyp object
- New HYP unsharing mechanism, finally allowing pages to be
unmapped from the Stage-1 EL2 page-tables
- Various pKVM cleanups around refcounting and sharing
- A couple of vgic fixes for bugs that would trigger once
the vcpu xarray rework is merged, but not sooner
- Add minimal support for ARMv8.7's PMU extension
- Rework kvm_pgtable initialisation ahead of the NV work
- New selftest for IRQ injection
- Teach selftests about the lack of default IPA space and
page sizes
- Expand sysreg selftest to deal with Pointer Authentication
- The usual bunch of cleanups and doc update

Include into the path manager status a bitmap tracking the list
of local endpoints still available - not yet used - for the
relevant mptcp socket.
Keep such map updated at endpoint creation/deletion time, so
that we can easily skip already used endpoint at local address
selection time.
The endpoint used by the initial subflow is lazyly accounted at
subflow creation time: the usage bitmap is be up2date before
endpoint selection and we avoid such unneeded task in some relevant
scenarios - e.g. busy servers accepting incoming subflows but
not creating any additional ones nor annuncing additional addresses.
Overall this allows for fair local endpoints usage in case of
subflow failure.
As a side effect, this patch also enforces that each endpoint
is used at most once for each mptcp connection.

PT_REGS*() macro on some architectures force-cast struct pt_regs to
other types (user_pt_regs, etc) and might drop volatile modifiers, if any.
Volatile isn't really required as pt_regs value isn't supposed to change
during the BPF program run, so this is correct behavior.
But progs/loop3.c relies on that volatile modifier to ensure that loop
is preserved. Fix loop3.c by declaring i and sum variables as volatile
instead. It preserves the loop and makes the test pass on all
architectures (including s390x which is currently broken).

The tc_redirect umounts /sys in the new namespace, which can be
mounted as shared and cause global umount. The lazy umount also
takes down mounted trees under /sys like debugfs, which won't be
available after sysfs mounts again and could cause fails in other
tests.
# cat /proc/self/mountinfo | grep debugfs
34 23 0:7 / /sys/kernel/debug rw,nosuid,nodev,noexec,relatime shared:14 - debugfs debugfs rw
# cat /proc/self/mountinfo | grep sysfs
23 86 0:22 / /sys rw,nosuid,nodev,noexec,relatime shared:2 - sysfs sysfs rw
# mount | grep debugfs
debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime)
# ./test_progs -t tc_redirect
#164 tc_redirect:OK
Summary: 1/4 PASSED, 0 SKIPPED, 0 FAILED
# mount | grep debugfs
# cat /proc/self/mountinfo | grep debugfs
# cat /proc/self/mountinfo | grep sysfs
25 86 0:22 / /sys rw,relatime shared:2 - sysfs sysfs rw
Making the sysfs private under the new namespace so the umount won't
trigger the global sysfs umount.

The get-reg-list test ignores the Pointer Authentication features,
which is a shame now that we have relatively common HW with this feature.
Define two new configurations (with and without PMU) that exercise the

Currently, userfaultfd selftest for hugetlb as run from run_vmtests.sh
or any environment where there are 'just enough' hugetlb pages will
always fail with:
testing events (fork, remap, remove):
ERROR: UFFDIO_COPY error: -12 (errno=12, line=616)
The ENOMEM error code implies there are not enough hugetlb pages.
However, there are free hugetlb pages but they are all reserved. There
is a basic problem with the way the test allocates hugetlb pages which
has existed since the test was originally written.
Due to the way 'cleanup' was done between different phases of the test,
this issue was masked until recently. The issue was uncovered by commit
8ba6e8640844 ("userfaultfd/selftests: reinitialize test context in each
test").
For the hugetlb test, src and dst areas are allocated as PRIVATE
mappings of a hugetlb file. This means that at mmap time, pages are
reserved for the src and dst areas. At the start of event testing (and
other tests) the src area is populated which results in allocation of
huge pages to fill the area and consumption of reserves associated with
the area. Then, a child is forked to fault in the dst area. Note that
the dst area was allocated in the parent and hence the parent owns the
reserves associated with the mapping. The child has normal access to
the dst area, but can not use the reserves created/owned by the parent.
Thus, if there are no other huge pages available allocation of a page
for the dst by the child will fail.
Fix by not creating reserves for the dst area. In this way the child
can use free (non-reserved) pages.
Also, MAP_PRIVATE of a file only makes sense if you are interested in
the contents of the file before making a COW copy. The test does not do
this. So, just use MAP_ANONYMOUS | MAP_HUGETLB to create an anonymous
hugetlb mapping. There is no need to create a hugetlb file in the
non-shared case.
