selftests: net: add macvlan multicast test for shared source MAC
Add a selftest that verifies multicast delivery to a macvlan bridge port when the source MAC of the incoming frame matches the macvlan's own MAC address. This scenario occurs with protocols like VRRP where multiple hosts share the same virtual MAC address. Without the corresponding kernel change, macvlan bridge mode does not handle this case and the multicast frame is not delivered.

selftests: netconsole: print diagnostic on busywait timeout in netcons_basic
The script uses set -euo pipefail, so when busywait times out waiting
for the netconsole message to arrive, it returns 1 and the script exits
immediately without printing any error message. As reported by Jakub,
this makes failures hard to diagnose since the test reports exit=1 with
no explanation.
Handle the busywait failure explicitly so that a FAIL message is printed
before exiting. This is how it looks like now:
Running with target mode: basic (ipv6)
[ 167.452561] netconsole selftest: netcons_QdMay
FAIL: Timed out waiting (20000 ms) for netconsole message in /tmp/netcons_QdMay
The remaining silent failures under set -e can only happen during the
setup phase (netdevsim creation, interface configuration, configfs
writes). So, it is not expected to have any silent failure once the test
starts.
Note that this issue might be less frequent now, since commit

selftest: net: Add basic functionality tests for ipmr.
The new test exercise paths, where RTNL is needed, to
catch lockdep splat:
setsockopt
MRT_INIT / MRT_DONE
MRT_ADD_VIF / MRT_DEL_VIF
MRT_ADD_MFC / MRT_DEL_MFC / MRT_ADD_MFC_PROXY / MRT_DEL_MFC_PROXY
MRT_TABLE
MRT_FLUSH
rtnetlink
RTM_NEWROUTE

selftests: drv-net: iou-zcrx: allocate hugepages for large chunks test
The large chunks test needs 2MB hugepages for its mmap allocation, but the test system may not have any pre-allocated. Ensure at least 64 hugepages are available before running the test, and restore the original value on cleanup. While at it strip the stdout, it has a trailing new line. Before: ok 5 iou-zcrx.test_zcrx_large_chunks # SKIP Can't allocate huge pages Link: https://patch.msgid.link/20260227171305.2848240-4-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

selftests: drv-net: iou-zcrx: wait for memory provider cleanup
io_uring defers zcrx context teardown to the iou_exit workqueue.
# ps aux | grep iou
... 07:58 0:00 [kworker/u19:0-iou_exit]
... 07:58 0:00 [kworker/u18:2-iou_exit]
When the test's receiver process exits, bkg() returns but the memory
provider may still be attached to the rx queue. The subsequent defer()
that restores tcp-data-split then fails:
# Exception while handling defer / cleanup (callback 3 of 3)!
# Defer Exception| net.ynl.pyynl.lib.ynl.NlError:
Netlink error: can't disable tcp-data-split while device has
memory provider enabled: Invalid argument
not ok 1 iou-zcrx.test_zcrx.single
Add a helper that polls netdev queue-get until no rx queue reports
the io-uring memory provider attribute. Register it as a defer()
just before tcp-data-split is restored as a "barrier".

selftests/vsock: change tests to respect write-once child ns mode
The child_ns_mode sysctl parameter becomes write-once in a future patch in this series, which breaks existing tests. This patch updates the tests to respect this new policy. No additional tests are added. Add "global-parent" and "local-parent" namespaces as intermediaries to spawn namespaces in the given modes. This avoids the need to change "child_ns_mode" in the init_ns. nsenter must be used because ip netns unshares the mount namespace so nested "ip netns add" breaks exec calls from the init ns. Adds nsenter to the deps check.

selftests: hw-net: tso: set a TCP window clamp to avoid spurious drops
The TSO test wants to make sure that there isn't a lot of retransmits, because that could indicate that device has a buggy TSO implementation. On debug kernels, however, we're likely to see significant packet loss because we simply overwhelm the receiver. In a QEMU loop with virtio devices we see ~10% false positive rate with occasional run hitting the threshold of 25% packet loss. Since we're only sending 4MB of data, set a TCP_WINDOW_CLAMP to 200k. This seems to make virtio happy while having little impact since we're primarily interested in testing the sender, and the test doesn't currently enable BIG TCP. Running socat over virtio loop for 2 sec on a debug kernel shows: TcpOutSegs 27327 0.0 TcpRetransSegs 83 0.0 TcpOutSegs 30012 0.0 TcpRetransSegs 80 0.0 TcpOutSegs 28767 0.0 TcpRetransSegs 77 0.0 But with the clamp the 3 attempts show no retransmit: TcpOutSegs 31537 0.0 TcpRetransSegs 0 0.0 TcpOutSegs 30323 0.0 TcpRetransSegs 0 0.0 TcpOutSegs 28700 0.0 TcpRetransSegs 0 0.0 Since we expect no receiver-related drops now we can significantly increase test's sensitivity to drops. All the testing we do in NIPA uses cubic. Link: https://patch.msgid.link/20260223204030.4142884-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

# Exception| lib.py.utils.CmdInitFailure: Did not receive ready message
# Exception| CMD: false
# Exception| EXIT: 1
We need to factor out _process_terminate() otherwise the exit

selftests: net: py: avoid masking exceptions in bkg() failures
bkg() failures are currently quite hard to debug and spot.
Often we have code along the lines of:
with bkg("./cmd_rx_something -p PORT"):

When wait_port_listen() fails we don't get to see the exit status
of bkg(). Even tho very often it's a failure in the bkg() command
that's actually to blame. Try not to interfere with the bkg()
command error checking.

with bkg("false", exit_wait=True):
time.sleep(0.01) # let the 'false' cmd run
raise Exception("bla")

selftests: tc_actions: don't dump 2MB of \0 to stdout
Since we started running selftests in NIPA we have been seeing
tc_actions.sh generate a soft lockup warning on ~20% of the runs.
On the pre-netdev foundation setup it was actually a missed irq
splat from the console. Now it's either that or a lockup.
I initially suspected a socket locking issue since the test
is exercising local loopback with act_mirred.
After hours of staring at this I noticed in strace that ncat
when -o $file is specified _both_ saves the output to the file
and still prints it to stdout. Because the file being sent
is constructed with:
dd conv=sparse status=none if=/dev/zero bs=1M count=2 of=$mirred
^^^^^^^^^
the data printed is all \0. Most terminals don't display nul
characters (and neither does vng output capture save them).
But QEMU's serial console still has to poke them thru which
is very slow and causes the lockup (if the file is >600kB).
Replace the '-o $file' with '> $file'. This speeds the test up
from 2m20s to 18s on debug kernels, and prevents the warnings.

selftests: forwarding: fix pedit tests failure with br_netfilter enabled
The tests use the tc pedit action to modify the IPv4 source address
("pedit ex munge ip src set"), but the IP header checksum is not
recalculated after the modification. As a result, the modified packet
fails sanity checks in br_netfilter after bridging and is dropped,
which causes the test to fail.
Fix this by ensuring net.bridge.bridge-nf-call-iptables is set to 0
during the test execution. This prevents the bridge from passing
L2 traffic to netfilter, bypassing the checksum validation that
causes the test failure.

selftests: forwarding: vxlan_bridge_1d_ipv6: fix test failure with br_netfilter enabled
The test generates VXLAN traffic using mausezahn, where the encapsulated
inner IPv6 packet has an incorrect payload length set in the IPv6 header.
After VXLAN decapsulation, such packets do not pass sanity checks in
br_netfilter and are dropped, which causes the test to fail.
Fix this by setting the correct IPv6 payload length for the encapsulated
packet generated by mausezahn, so that the packet is accepted
by br_netfilter.

selftests: drv-net: add HDS payload sweep test for devmem TCP
Add check_rx_hds test that verifies header/data split works across payload sizes. The test sweeps payload sizes from 1 byte to 8KB, if any data propagates up to userspace as SCM_DEVMEM_LINEAR, then the test fails. This shows that regardless of payload size, ncdevmem's configuration of hds-thresh to 0 is respected. Add -L (--fail-on-linear) flag to ncdevmem that causes the receiver to fail if any SCM_DEVMEM_LINEAR cmsg is received. Use socat option for fixed block sizing and tcp nodelay to disable nagle's algo to avoid buffering.

ARM: - Add support for FEAT_IDST, allowing ID registers that are not implemented to be reported as a normal trap rather than as an UNDEF exception. - Add sanitisation of the VTCR_EL2 register, fixing a number of UXN/PXN/XN bugs in the process. - Full handling of RESx bits, instead of only RES0, and resulting in SCTLR_EL2 being added to the list of sanitised registers. - More pKVM fixes for features that are not supposed to be exposed to guests. - Make sure that MTE being disabled on the pKVM host doesn't give it the ability to attack the hypervisor. - Allow pKVM's host stage-2 mappings to use the Force Write Back version of the memory attributes by using the "pass-through' encoding. - Fix trapping of ICC_DIR_EL1 on GICv5 hosts emulating GICv3 for the guest. - Preliminary work for guest GICv5 support. - A bunch of debugfs fixes, removing pointless custom iterators stored in guest data structures. - A small set of FPSIMD cleanups. - Selftest fixes addressing the incorrect alignment of page allocation. - Other assorted low-impact fixes and spelling fixes. RISC-V: - Fixes for issues discoverd by KVM API fuzzing in kvm_riscv_aia_imsic_has_attr(), kvm_riscv_aia_imsic_rw_attr(), and kvm_riscv_vcpu_aia_imsic_update() - Allow Zalasr, Zilsd and Zclsd extensions for Guest/VM - Transparent huge page support for hypervisor page tables - Adjust the number of available guest irq files based on MMIO register sizes found in the device tree or the ACPI tables - Add RISC-V specific paging modes to KVM selftests - Detect paging mode at runtime for selftests s390: - Performance improvement for vSIE (aka nested virtualization) - Completely new memory management. s390 was a special snowflake that enlisted help from the architecture's page table management to build hypervisor page tables, in particular enabling sharing the last level of page tables. This however was a lot of code (~3K lines) in order to support KVM, and also blocked several features. The biggest advantages is that the page size of userspace is completely independent of the page size used by the guest: userspace can mix normal pages, THPs and hugetlbfs as it sees fit, and in fact transparent hugepages were not possible before. It's also now possible to have nested guests and guests with huge pages running on the same host. - Maintainership change for s390 vfio-pci - Small quality of life improvement for protected guests x86: - Add support for giving the guest full ownership of PMU hardware (contexted switched around the fastpath run loop) and allowing direct access to data MSRs and PMCs (restricted by the vPMU model). KVM still intercepts access to control registers, e.g. to enforce event filtering and to prevent the guest from profiling sensitive host state. This is more accurate, since it has no risk of contention and thus dropped events, and also has significantly less overhead. For more information, see the commit message for merge commit |

selftests/sched_ext: Fix rt_stall flaky failure
The rt_stall test measures the runtime ratio between an EXT and an RT
task pinned to the same CPU, verifying that the deadline server prevents
RT tasks from starving SCHED_EXT tasks. It expects the EXT task to get
at least 4% of CPU time.
The test is flaky because sched_stress_test() calls sleep(RUN_TIME)
immediately after fork(), without waiting for the RT child to complete
its setup (set_affinity + set_sched). If the RT child experiences
scheduling latency before completing setup, that delay eats into the
measurement window: the RT child runs for less than RUN_TIME seconds,
and the EXT task's measured ratio drops below the 4% threshold.
For example, in the failing CI run [1]:
EXT=0.140s RT=4.750s total=4.890s (expected ~5.0s)
ratio=2.86% < 4% → FAIL
The 110ms gap (5.0 - 4.89) corresponds to the RT child's setup time
being counted inside the measurement window, during which fewer
deadline server ticks fire for the EXT task.
Fix by using pipes to synchronize: each child signals the parent after
completing its setup, and the parent waits for both signals before
starting sleep(RUN_TIME). This ensures the measurement window only
counts time when both tasks are fully configured and competing.

selftests: mlxsw: tc_restrictions: Fix test failure with new iproute2
As explained in [1], iproute2 started rejecting tc-police burst sizes
that result in an overflow. This can happen when the burst size is high
enough and the rate is low enough.
A couple of test cases specify such configurations, resulting in
iproute2 errors and test failure.
Fix by reducing the burst size so that the test will pass with both new
and old iproute2 versions.
