commit 9168ea02b898d3dde98b51e4bd3fb082bd438dab upstream.
The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's
1, wait_rm_addr/sf will never break, and will loop ten times, then
'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long,
which can sometimes make the tests fail.
A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain
the current value, and then pass into wait_rm_addr/sf.

This patch fixes them by changing 'speed' to 5 to run the tests much more
slowly.

In the PMTU test, when all previous tests are skipped and the new test
passes, the exit code is set to 0. However, the current check mistakenly
treats this as an assignment, causing the check to pass every time.
Consequently, regardless of how many tests have failed, if the latest test
passes, the PMTU test will report a pass.

It is all too easy to get confused about @dev usage in the CXL driver
stack. Before adding a new cxl_pci_probe() setup operation that has a
devm lifetime dependent on @cxlds->dev binding, but also references
@cxlmd->dev, and prints messages, rework the devm_cxl_add_memdev() and
cxl_memdev_setup_fw_upload() function signatures to make this
distinction explicit. I.e. pass in the devm context as an @host argument
rather than infer it from other objects.
This is in preparation for adding a devm_cxl_sanitize_setup_notifier().
Note the whitespace fixup near the change of the devm_cxl_add_memdev()
signature. That uncaught typo originated in the patch that added
cxl_memdev_security_init().

I checked with the original author, the mmap_FIXED test case wasn't
properly tested and fails. Currently, it maps two consecutive (non
overlapping) pages and expects the second mapping to be denied by MDWE but
these two pages have nothing to do with each other so MDWE is actually out
of the picture here.
What the test actually intended to do was to remap a virtual address using
MAP_FIXED. However, this operation unmaps the existing mapping and
creates a new one so the va is backed by a new page and MDWE is again out
of the picture, all remappings should succeed.
This patch keeps the test case to make it clear that this situation is
expected to work: MDWE shouldn't block a MAP_FIXED replacement.

The linked list failure test 'pop_front_off' and 'pop_back_off'
currently rely on matching exact instruction and register values. The
purpose of the test is to ensure the offset is correctly incremented for
the returned pointers from list pop helpers, which can then be used with
container_of to obtain the real object. Hence, somehow obtaining the
information that the offset is 48 will work for us. Make the test more
robust by relying on verifier error string of bpf_spin_lock and remove
dependence on fragile instruction index or register number, which can be
affected by different clang versions used to build the selftests.

Assume that caller's 'to' offset really represents an upper boundary for
the pattern search, so patterns extending past this offset are to be
rejected.
The old behaviour also was kind of inconsistent when it comes to
fragmentation (or otherwise non-linear skbs): If the pattern started in
between 'to' and 'from' offsets but extended to the next fragment, it
was not found if 'to' offset was still within the current fragment.
Test the new behaviour in a kselftest using iptables' string match.

Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as fairly
clear-cut user reported regressions. The mlx5 DMA bug was causing strife
for 390x folks. The fixes themselves are not particularly scary, tho.
No open investigations / outstanding reports at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations,
make devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve,
previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset",
needs more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting,
it was denied to plug a constant source of bugs but turns out
.NET depends on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560",
it's causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains
a single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding
(bless Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers
- mptcp: avoid sending RST when closing the initial subflow

Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, netfilter, WiFi.
Feels like an up-tick in regression fixes, mostly for older releases.
The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
fairly clear-cut user reported regressions. The mlx5 DMA bug was
causing strife for 390x folks. The fixes themselves are not
particularly scary, tho. No open investigations / outstanding reports
at the time of writing.
Current release - regressions:
- eth: mlx5: perform DMA operations in the right locations, make
devices usable on s390x, again
- sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
curve, previous fix of rejecting invalid config broke some scripts
- rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock
- revert "ethtool: Fix mod state of verbose no_mask bitset", needs
more work
Current release - new code bugs:
- tcp: fix listen() warning with v4-mapped-v6 address
Previous releases - regressions:
- tcp: allow tcp_disconnect() again when threads are waiting, it was
denied to plug a constant source of bugs but turns out .NET depends
on it
- eth: mlx5: fix double-free if buffer refill fails under OOM
- revert "net: wwan: iosm: enable runtime pm support for 7560", it's
causing regressions and the WWAN team at Intel disappeared
- tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
single skb, fix single-stream perf regression on some devices
Previous releases - always broken:
- Bluetooth:
- fix issues in legacy BR/EDR PIN code pairing
- correctly bounds check and pad HCI_MON_NEW_INDEX name
- netfilter:
- more fixes / follow ups for the large "commit protocol" rework,
which went in as a fix to 6.5
- fix null-derefs on netlink attrs which user may not pass in
- tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
Debian for keeping HZ=250 alive)
- net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
letting frankenstein UDP super-frames from getting into the stack
- net: fix interface altnames when ifc moves to a new namespace
- eth: qed: fix the size of the RX buffers
- mptcp: avoid sending RST when closing the initial subflow"

The commit mentioned below was more tolerant with the number of RST seen
during a test because in some uncontrollable situations, multiple RST
can be generated.
But it was not taking into account the case where no RST are expected:
this validation was then no longer reporting issues for the 0 RST case
because it is not possible to have less than 0 RST in the counter. This
patch fixes the issue by adding a specific condition.

Kernels that don't have support for openvswitch drop reasons also

completely. It previously wasn't possible to build a test case
for this without polluting the datapath, so we introduce a mechanism
to clear all the flows from a datapath allowing us to test for
explicit drop actions, and then clear the flows to build the
original test case.

Paolo Abeni reports that on some systems the pyroute2 version isn't
new enough to run the test suite. Ensure that we support a minimum
version of 0.6 for all cases (which does include the existing ones).
The 0.6.1 version was released in May of 2021, so should be
propagated to most installations at this point.
The alternative that Paolo proposed was to only skip when the
add-flow is being run. This would be okay for most cases, except
if a future test case is added that needs to do flow dump without
an associated add (just guessing). In that case, it could also be
broken and we would need additional skip logic anyway. Just draw
a line in the sand now.

- Play nice with %llx when formatting guest printf and assert statements.
- Clean up stale test metadata.
- Zero-initialize structures in memslot perf test to workaround a suspected
"may be used uninitialized" false positives from GCC.
The tests rely on the IPv{4,6} FIB trace points being triggered once for
each forwarded packet. If receive processing is deferred to the
ksoftirqd task these invocations will not be counted and the tests will
fail. Fix by specifying the '-a' flag to avoid perf from filtering on
the mausezahn task.

Extend x86's state to forcefully load *all* host-supported xfeatures by
modifying xstate_bv in the saved state. Stuffing xstate_bv ensures that
the selftest is verifying KVM's full ABI regardless of whether or not the

state, e.g. see the disaster that is/was MPX.

Expand x86's state test to load XSAVE state into a "dummy" vCPU prior to
KVM_SET_CPUID2, and again with an empty guest CPUID model. Except for
off-by-default features, i.e. AMX, KVM's ABI for KVM_SET_XSAVE is that
userspace is allowed to load xfeatures so long as they are supported by
the host. This is a regression test for a combination of KVM bugs where
the state saved by KVM_GET_XSAVE{2} could not be loaded via KVM_SET_XSAVE
if the saved xstate_bv would load guest-unsupported xfeatures.

Martin reported that on his local dev machine the test_tc_chain_mixed() fails as
"test_tc_chain_mixed:FAIL:seen_tc5 unexpected seen_tc5: actual 1 != expected 0"
and others occasionally, too.
However, when running in a more isolated setup (qemu in particular), it works fine
for him. The reason is that there is a small race-window where seen_tc* could turn
into true for various test cases when there is background traffic, e.g. after the
asserts they often get reset. In such case when subsequent detach takes place,
unrelated background traffic could have already flipped the bool to true beforehand.
Add a small helper tc_skel_reset_all_seen() to reset all bools before we do the ping
test. At this point, everything is set up as expected and therefore no race can occur.
All tc_{opts,links} tests continue to pass after this change.

Simplify __assert_mprog_count() to remove the -ENOENT corner case as the
bpf_prog_query() now returns 0 when no bpf_mprog is attached. This also
allows to convert a few test cases from using raw __assert_mprog_count()
over to plain assert_mprog_count() helper.

Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

Zero-initialize the entire test_result structure used by memslot_perf_test
instead of zeroing only the fields used to guard the pr_info() calls.
gcc 13.2.0 is a bit overzealous and incorrectly thinks that rbestslottime's
slot_runtime may be used uninitialized.
In file included from memslot_perf_test.c:25:
memslot_perf_test.c: In function ‘main’:
include/test_util.h:31:22: error: ‘rbestslottime.slot_runtime.tv_nsec’ may be used uninitialized [-Werror=maybe-uninitialized]

memslot_perf_test.c:1092:28: note: ‘rbestslottime.slot_runtime.tv_sec’ was declared here
1092 | struct test_result rbestslottime;
| ^~~~~~~~~~~~~
That can't actually happen, at least not without the "result" structure in
test_loop() also being used uninitialized, which gcc doesn't complain
about, as writes to rbestslottime are all-or-nothing, i.e. slottimens can't
be non-zero without slot_runtime being written.
if (!data->mem_size &&
(!rbestslottime->slottimens ||
result.slottimens < rbestslottime->slottimens))
*rbestslottime = result;
Zero-initialize the structures to make gcc happy even though this is
likely a compiler bug. The cost to do so is negligible, both in terms of
code and runtime overhead. The only downside is that the compiler won't
warn about legitimate usage of "uninitialized" data, e.g. the test could
end up consuming zeros instead of useful data. However, given that the
test is quite mature and unlikely to see substantial changes, the odds of
introducing such bugs are relatively low, whereas being able to compile
KVM selftests with -Werror detects issues on a regular basis.

netfilter patches for net
First patch resolves a regression with vlan header matching, this was
broken since 6.5 release. From myself.
Second patch fixes an ancient problem with sctp connection tracking in
case INIT_ACK packets are delayed. This comes with a selftest, both
patches from Xin Long.
Patch 4 extends the existing nftables audit selftest, from
Phil Sutter.
Patch 5, also from Phil, avoids a situation where nftables
would emit an audit record twice. This was broken since 5.13 days.
Patch 6, from myself, avoids spurious insertion failure if we encounter an
overlapping but expired range during element insertion with the
'nft_set_rbtree' backend. This problem exists since 6.2.

Treat %ll* formats the same as %l* formats when processing printfs from
the guest so that using e.g. %llx instead of %lx generates the expected
output. Ideally, unexpected formats would generate compile-time warnings
or errors, but it's not at all obvious how to actually accomplish that.
Alternatively, guest_vsnprintf() could assert on an unexpected format,
but since the vast majority of printfs are for failed guest asserts,
getting *something* printed is better than nothing.
