The current test scripts contain duplicated root permission checks in
multiple locations. This patch consolidates these checks into _common.sh

Patch series "selftests/damon/sysfs.py: test all parameters".
sysfs.py tests if DAMON sysfs interface is passing the user-requested
parameters to DAMON as expected. But only the default (minimum)
parameters are being tested. This is partially because _damon_sysfs.py,
which is the library for making the parameter requests, is not supporting
the entire parameters. The internal DAMON status dump script
(drgn_dump_damon_status.py) is also not dumping entire parameters. Extend
the test coverage by updating parameters input and status dumping scripts
to support all parameters, and writing additional tests using those.
This increased test coverage actually found one real bug
(https://lore.kernel.org/20250719181932.72944-1-sj@kernel.org).
First seven patches (1-7) extend _damon_sysfs.py for all parameters setup.
The eight patch (8) fixes _damon_sysfs.py to use correct max nr_acceses
and age values for their type. Following three patches (9-11) extend
drgn_dump_damon_status.py to dump full DAMON parameters. Following nine
patches (12-20) refactor sysfs.py for general testing code reuse, and
extend it for full parameters check. Finally, two patches (21 and 22) add
test cases in sysfs.py for full parameters testing.
This patch (of 22):
_damon_sysfs.py contains code for test-purpose DAMON sysfs interface
control. Add support of DAMOS watermarks setup for more tests.

Commit 4ece01897627 ("selftests/damon: add python and drgn-based DAMON
sysfs test") in mm-stable tree introduced sysfs.py that runs drgn for
dumping DAMON status. When the DAMON status dumping fails for reasons
including drgn uninstalled environment, the test fails without stopping
DAMON. Following DAMON selftests that assumes DAMON is not running when
they executed therefore fail. Catch dumping failures and stop DAMON for
that case.

The esp4_offload module, loaded during IPsec offload tests, should
be reset to its default settings after testing.
Otherwise, leaving it enabled could unintentionally affect subsequence

PASS: ipsec_offload

With arm64 64K page size, the following 4 subtests failed:
#97/25 dynptr/test_probe_read_user_dynptr:FAIL
#97/26 dynptr/test_probe_read_kernel_dynptr:FAIL
#97/27 dynptr/test_probe_read_user_str_dynptr:FAIL
#97/28 dynptr/test_probe_read_kernel_str_dynptr:FAIL
These failures are due to function bpf_dynptr_check_off_len() in
include/linux/bpf.h where there is a test
if (len > size || offset > size - len)
return -E2BIG;
With 64K page size, the 'offset' is greater than 'size - len',
which caused the test failure.
For 64KB page size, this patch increased the xdp buffer size from 5000 to
90000. The above 4 test failures are fixed as 'size' value is increased.
But it introduced two new failures:
#97/4 dynptr/test_dynptr_copy_xdp:FAIL
#97/12 dynptr/test_dynptr_memset_xdp_chunks:FAIL
These two failures will be addressed in subsequent patches.

Currently, UDP exchange is prone to failure when cmd attempt to send data
while socat in bkg is not ready. Since, the behavior is probabilistic, this
can result in flakiness for XDP tests. While testing
test_xdp_native_tx_mb() on netdevsim, a failure rate of around 1% in 500
500 iterations was observed.
Use wait_port_listen() to ensure that the bkg socat is started and ready to
receive before cmd start sending. With proposed changes, a re-run of the
same test passed 100% of time.

It is currently impossible to enable ipv6 forwarding on a per-interface
basis like in ipv4. To enable forwarding on an ipv6 interface we need to
enable it on all interfaces and disable it on the other interfaces using
a netfilter rule. This is especially cumbersome if you have lots of
interfaces and only want to enable forwarding on a few. According to the
sysctl docs [0] the `net.ipv6.conf.all.forwarding` enables forwarding
for all interfaces, while the interface-specific
`net.ipv6.conf.<interface>.forwarding` configures the interface
Host/Router configuration.
Introduce a new sysctl flag `force_forwarding`, which can be set on every
interface. The ip6_forwarding function will then check if the global
forwarding flag OR the force_forwarding flag is active and forward the
packet.
To preserve backwards-compatibility reset the flag (on all interfaces)
to 0 if the net.ipv6.conf.all.forwarding flag is set to 0.
Add a short selftest that checks if a packet gets forwarded with and
without `force_forwarding`.

Extend the `check_for_dependencies()` function in `lib_netcons.sh` to check
whether IPv6 is enabled by verifying the existence of
`/proc/net/if_inet6`. Having IPv6 is a now a dependency of netconsole
tests. If the file does not exist, the script will skip the test with an
appropriate message suggesting to verify if `CONFIG_IPV6` is enabled.
This prevents the test to misbehave if IPv6 is not configured.

Although setup_ns() set net.ipv4.conf.default.rp_filter=0,
loading certain module such as ipip will automatically create a tunl0 interface
in all netns including new created ones. In the script, this is before than
default.rp_filter=0 applied, as a result tunl0.rp_filter remains set to 1
which causes the test report FAIL when ipip module is preloaded.
Before fix:

Some specified options rely on NETFILTER_XTABLES_LEGACY to be enabled.
IP_NF_TARGET_TTL for instance depends on IP_NF_MANGLE which in turn
depends on IP_NF_IPTABLES_LEGACY -> NETFILTER_XTABLES_LEGACY.
Enable relevant iptables config options explicitly, this is needed
to avoid breakage when symbols related to iptables-legacy
will depend on NETFILTER_LEGACY resp. IP_TABLES_LEGACY.
This also means that the classic tables (Kernel modules) will
not be enabled by default, so enable them too.

Check that moving a range of VMAs where we are offset into the first and
last VMAs works correctly.
This results in the VMAs being split at these points at which we are offset
into VMAs.
We explicitly test both the ordinary MREMAP_FIXED multi VMA move case and
the MREMAP_DONTUNMAP multi VMA move case.

We support MREMAP_MAYMOVE | MREMAP_FIXED | MREMAP_DONTUNMAP for moving
multiple VMAs via mremap(), so assert that the tests pass with both
MREMAP_DONTUNMAP set and not set.
Additionally, add success = false settings when mremap() fails. This is
something that cannot realistically happen, so in no way impacted test
outcome, but it is incorrect to indicate a test pass when something has
failed.

Patch series "tools/testing: expand mremap testing".
Expand our mremap() testing to further assert that behaviour is as
expected.
There is a poorly documented mremap() feature whereby it is possible to
mremap() multiple VMAs (even with gaps) when shrinking, as long as the
resultant shrunk range spans only a single VMA.
So we start by asserting this behaviour functions correctly both with an
in-place shrink and a shrink/move.
Next, we further test the newly introduced ability to mremap() multiple
VMAs when performing a MAP_FIXED move (that is without the size being
changed), firstly by asserting that MREMAP_DONTUNMAP has no bearing on
this behaviour.
Finally, we explicitly test that such moves, when splitting source VMAs,
function correctly.
This patch (of 3):
There is an apparently little-known feature of mremap() whereby, in stark
contrast to other modes (other than the recently introduced capacity to
move multiple VMAs), the input source range span multiple VMAs with gaps
between.
This is, when shrinking a VMA, whether moving it or not, and the shrink
would reduce the range to a single VMA - this is permitted, as the shrink
is actioned by an unmap.
This patch adds tests to assert that this behaves as expected.
