f18fa2abf8 selftests: mptcp: join: check re-re-adding ID 0 signal
This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.

This test extends "delete and re-add" to validate the previous commit:
when the endpoint linked to the initial subflow (ID 0) is re-added

1c2326fcae selftests: mptcp: join: check re-adding init endp with != id
The initial subflow has a special local ID: 0. It is specific per
connection.

When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.

This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.

Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

5f94b08c00 selftests: mptcp: join: check removing ID 0 endpoint
Removing the endpoint linked to the initial subflow should trigger a
RM_ADDR for the right ID, and the removal of the subflow. That's what is
now being verified in the "delete and re-add" test.

Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

e93681afcb selftests: mptcp: join: cannot rm sf if closed
Thanks to the previous commit, the MPTCP subflows are now closed on both
directions even when only the MPTCP path-manager of one peer asks for
their closure.

In the two tests modified here -- "userspace pm add & remove address"
and "userspace pm create destroy subflow" -- one peer is controlled by
the userspace PM, and the other one by the in-kernel PM. When the
userspace PM sends a RM_ADDR notification, the in-kernel PM will
automatically react by closing all subflows using this address. Now,
thanks to the previous commit, the subflows are properly closed on both
directions, the userspace PM can then no longer closes the same
subflows if they are already closed. Before, it was OK to do that,
because the subflows were still half-opened, still OK to send a RM_ADDR.

In other words, thanks to the previous commit closing the subflows, an
error will be returned to the userspace if it tries to close a subflow
that has already been closed. So no need to run this command, which mean
that the linked counters will then not be incremented.

These tests are then no longer sending both a RM_ADDR, then closing the
linked subflow just after. The test with the userspace PM on the server
side is now removing one subflow linked to one address, then sending
a RM_ADDR for another address. The test with the userspace PM on the
client side is now only removing the subflow that was previously
created.

052f395164 selftests/livepatch: wait for atomic replace to occur
On some machines with a large number of CPUs there is a sizable delay
between an atomic replace occurring and when sysfs updates accordingly.
This fix uses 'loop_until' to wait for the atomic replace to unload all
previous livepatches.

996dc53ac2 iommufd: Do not allow creating areas without READ or WRITE
This results in passing 0 or just IOMMU_CACHE to iommu_map(). Most of
the page table formats don't like this:

  amdv1 - -EINVAL
  armv7s - returns 0, doesn't update mapped
  arm-lpae - returns 0 doesn't update mapped
  dart - returns 0, doesn't update mapped
  VT-D - returns -EINVAL

Unfortunately the three formats that return 0 cause serious problems:

 - Returning ret = but not uppdating mapped from domain->map_pages()
   causes an infinite loop in __iommu_map()

 - Not writing ioptes means that VFIO/iommufd have no way to recover them
   and we will have memory leaks and worse during unmap

Since almost nothing can support this, and it is a useless thing to do,
block it early in iommufd.

This case was not covered, and the wrong ID was set before the previous
commit.

The rest is not modified, it is just that it will increase the code
coverage.

The right address ID can be verified by looking at the packet traces. We
could automate that using Netfilter with some cBPF code for example, but
that's always a bit cryptic. Packetdrill seems better fitted for that.

e29b82ef27 selftests: net: bridge_vlan_aware: test that other TPIDs are seen as untagged
The bridge VLAN implementation w.r.t. VLAN protocol is described in
merge commit 1a0b20b257 ("Merge branch 'bridge-next'"). We are only
sensitive to those VLAN tags whose TPID is equal to the bridge's
vlan_protocol. Thus, an 802.1ad VLAN should be treated as 802.1Q-untagged.

Add 3 tests which validate that:
- 802.1ad-tagged traffic is learned into the PVID of an 802.1Q-aware
  bridge
- Double-tagged traffic is forwarded when just the PVID of the port is
  present in the VLAN group of the ports
- Double-tagged traffic is not forwarded when the PVID of the port is
  absent from the VLAN group of the ports

The test passes with both veth and ocelot.

2379795042 selftests: net: local_termination: add PTP frames to the mix
A breakage in the felix DSA driver shows we do not have enough test
coverage. More generally, it is sufficiently special that it is likely
drivers will treat it differently.

This is not meant to be a full PTP test, it just makes sure that PTP
packets sent to the different addresses corresponding to their profiles
are received correctly. The local_termination selftest seemed like the
most appropriate place for this addition.

PTP RX/TX in some cases makes no sense (over a bridge) and this is why
$skip_ptp exists. And in others - PTP over a bridge port - the IP stack
needs convincing through the available bridge netfilter hooks to leave
the PTP packets alone and not stolen by the bridge rx_handler. It is
safe to assume that users have that figured out already. This is a
driver level test, and by using tcpdump, all that extra setup is out of
scope here.

send_non_ip() was an unfinished idea; written but never used.
Replace it with a more generic send_raw(), and send 3 PTP packet types
times 3 transports.

9aa3749ca4 selftests: net: local_termination: don't use xfail_on_veth()
xfail_on_veth() for this test is an incorrect approximation which gives
false positives and false negatives.

When local_termination fails with "reception succeeded, but should have failed",
it is because the DUT ($h2) accepts packets even when not configured as
promiscuous. This is not something specific to veth; even the bridge
behaves that way, but this is not captured by the xfail_on_veth test.

The IFF_UNICAST_FLT flag is not explicitly exported to user space, but
it can somewhat be determined from the interface's behavior. We have to
create a macvlan upper with a different MAC address. This forces a
dev_uc_add() call in the kernel. When the unicast filtering list is
not empty, but the device doesn't support IFF_UNICAST_FLT,
__dev_set_rx_mode() force-enables promiscuity on the interface, to
ensure correct behavior (that the requested address is received).

We can monitor the change in the promiscuity flag and infer from it
whether the device supports unicast filtering.

There is no equivalent thing for allmulti, unfortunately. We never know
what's hiding behind a device which has allmulti=off. Whether it will
actually perform RX multicast filtering of unknown traffic is a strong
"maybe". The bridge driver, for example, completely ignores the flag.
We'll have to keep the xfail behavior, but instead of XFAIL on just
veth, always XFAIL.

5fea8bb009 selftests: net: local_termination: introduce new tests which capture VLAN behavior
Add more coverage to the local termination selftest as follows:
- 8021q upper of $h2
- 8021q upper of $h2, where $h2 is a port of a VLAN-unaware bridge
- 8021q upper of $h2, where $h2 is a port of a VLAN-aware bridge
- 8021q upper of VLAN-unaware br0, which is the upper of $h2
- 8021q upper of VLAN-aware br0, which is the upper of $h2

Especially the cases with traffic sent through the VLAN upper of a
VLAN-aware bridge port will be immediately relevant when we will start
transmitting PTP packets as an additional kind of traffic.

5b8e74182e selftests: net: local_termination: add one more test for VLAN-aware bridges
The current bridge() test is for packet reception on a VLAN-unaware
bridge. Some things are different enough with VLAN-aware bridges that
it's worth renaming this test into vlan_unaware_bridge(), and add a new
vlan_aware_bridge() test.

The two will share the same implementation: bridge() becomes a common
function, which receives $vlan_filtering as an argument. Rename it to
test_bridge() at the same time, because just bridge() pollutes the
global namespace and we cannot invoke the binary with the same name from
the iproute2 package currently.

(or bridge port), but under differing vlan_filtering conditions.
Since we currently print $h2 (the DUT) in the log_test() output, it
becomes necessary to make a further distinction between tests, to not
give the user the impression that the exact same thing is run twice.

4261fa3518 selftests: net: local_termination: parameterize sending interface
In future changes we will want to subject the DUT, $h2, to additional
VLAN-tagged traffic. For that, we need to run the tests using $h1.100 as
a sending interface, rather than the currently hardcoded $h1.

Add a parameter to run_test() and modify its 2 callers to explicitly
pass $h1, as was implicit before.

7c5e8d212d selftests: memfd_secret: don't build memfd_secret test on unsupported arches
[1] mentions that memfd_secret is only supported on arm64, riscv, x86 and
x86_64 for now.  It doesn't support other architectures.  I found the
build error on arm and decided to send the fix as it was creating noise on
KernelCI:

memfd_secret.c: In function 'memfd_secret':
memfd_secret.c:42:24: error: '__NR_memfd_secret' undeclared (first use in this function);
did you mean 'memfd_secret'?
   42 |         return syscall(__NR_memfd_secret, flags);
      |                        ^~~~~~~~~~~~~~~~~
      |                        memfd_secret

Hence I'm adding condition that memfd_secret should only be compiled on
supported architectures.

Also check in run_vmtests script if memfd_secret binary is present before
executing it.

af3b7d09a9 selftests/mm: compaction_test: fix off by one in check_compaction()
The "initial_nr_hugepages" variable is unsigned long so it takes up to 20
characters to print, plus 1 more character for the NUL terminator. 
Unfortunately, this buffer is not quite large enough for the terminator to
fit.  Also use snprintf() for a belt and suspenders approach.

====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Ignores ifindex for types other than mcast/linklocal in ipv6 frag
   reasm, from Tom Hughes.

2) Initialize extack for begin/end netlink message marker in batch,
   from Donald Hunter.

3) Initialize extack for flowtable offload support, also from Donald.

4) Dropped packets with cloned unconfirmed conntracks in nfqueue,
   later it should be possible to explore lookup after reinject but
   Florian prefers this approach at this stage. From Florian Westphal.

5) Add selftest for cloned unconfirmed conntracks in nfqueue for
   previous update.

6) Audit after filling netlink header successfully in object dump,
   from Phil Sutter.

7-8) Fix concurrent dump and reset which could result in underflow
     counter / quota objects.

7965a7f32a selftests: net: lib: kill PIDs before del netns
When deleting netns, it is possible to still have some tasks running,
e.g. background tasks like tcpdump running in the background, not
stopped because the test has been interrupted.

Before deleting the netns, it is then safer to kill all attached PIDs,
if any. That should reduce some noises after the end of some tests, and
help with the debugging of some issues. That's why this modification is
seen as a "fix".

662c3e2db0 selftests/bpf: Add a test to verify previous stacksafe() fix
A selftest is added such that without the previous patch,
a crash can happen. With the previous patch, the test can
run successfully. The new test is written in a way which
mimics original crash case:
  main_prog
    static_prog_1
      static_prog_2
where static_prog_1 has different paths to static_prog_2
and some path has stack allocated and some other path
does not. A stacksafe() checking in static_prog_2()
triggered the crash.

1d2c46c1bc selftests/net: Add coverage for UDP GSO with IPv6 extension headers
After enabling UDP GSO for devices not offering checksum offload, we have
hit a regression where a bad offload warning can be triggered when sending
a datagram with IPv6 extension headers.

Extend the UDP GSO IPv6 tests to cover this scenario.

4bbe600293 perf daemon: Fix the build on 32-bit architectures
Noticed with:

   1     6.22 debian:experimental-x-mipsel  : FAIL gcc version 13.2.0 (Debian 13.2.0-25)
    builtin-daemon.c: In function 'cmd_session_list':

Use inttypes.h's PRIu64 to deal with that.

2c402bd2e8 cxl/test: Skip cxl_setup_parent_dport() for emulated dports
The cxl_test unit test environment on qemu always hits below call trace

cxl_test module models a CXL topology for testing, it creates some
emulated dports with platform devices in the CXL topology, so the
dport_dev of an emulated dport points to a platform device rather than a
pci device or a pci host bridge in the case. Currently,
cxl_setup_parent_dport() is used to set up RAS and AER capability on the
dport connected to the CXL memory device, but cxl_test does not support
RAS or AER functionality yet, so the fix is implementing a
__wrap_cxl_setup_parent_dport() to filter out all emulated dports,
guarantees only real dports can be handled by cxl_setup_parent_dport().
