A net device has a threaded sysctl that can be used to enable threaded
NAPI polling on all of the NAPI contexts under that device. Allow
enabling threaded NAPI polling at individual NAPI level using netlink.
Extend the netlink operation `napi-set` and allow setting the threaded
attribute of a NAPI. This will enable the threaded polling on a NAPI
context.
Add a test in `nl_netdev.py` that verifies various cases of threaded
NAPI being set at NAPI and at device level.

Added a test for variable PMTU in broadcast routes.
This test uses iputils' ping and attempts to send a ping between
two peers, which should result in a regular echo reply.
This test will fail when the receiving peer does not receive the echo
request due to a lack of packet fragmentation.

The iou-zcrx selftest currently runs the server on the remote host
and the client on the local host. This commit flips the endpoints
such that server runs on localhost and client on remote.
This change brings the iou-zcrx selftest in convention with other
selftests.
Drive-by fix for a missing import exception that happens when the
network interface has less than 2 combined channels.

The previous patch fixes a bug that prevented the creation of the
default IPv6 multicast route (ff00::/8) for some GRE devices. Now let's
extend the GRE IPv6 selftests to cover this case.
Also, rename check_ipv6_ll_addr() to check_ipv6_device_config() and
adapt comments and script output to take into account the fact that
we're not limited to link-local address generation.

In test_stream_transport_change_client(), the client sends CONTROL_CONTINUE
on each iteration, even when connect() is unsuccessful. This causes a flood
of control messages in the server that hangs around for more than 10
seconds after the test finishes, triggering several timeouts and causing
subsequent tests to fail. This was discovered in testing a newly proposed
test that failed in this way on the client side:
...
33 - SOCK_STREAM transport change null-ptr-deref...ok
34 - SOCK_STREAM ioctl(SIOCINQ) functionality...recv timed out
The CONTROL_CONTINUE message is used only to tell to the server to call
accept() to consume successful connections, so that subsequent connect()
will not fail for finding the queue full.
Send CONTROL_CONTINUE message only when the connect() has succeeded, or
found the queue full. Note that the second connect() can also succeed if
the first one was interrupted after sending the request.

Add IPv6 support to the netconsole basic functionality tests by:
- Introducing separate IPv4 and IPv6 address variables (SRCIP4/SRCIP6,
DSTIP4/DSTIP6) to replace the single SRCIP/DSTIP variables
- Adding select_ipv4_or_ipv6() function to choose protocol version
- Updating socat configuration to use UDP6-LISTEN for IPv6 tests
- Adding wait_for_port() wrapper to handle protocol-specific port waiting
- Expanding test matrix to run both basic and extended formats against
both IPv4 and IPv6 protocols
- Improving cleanup to kill any remaining socat processes
- Adding sleep delays for better IPv6 packet handling reliability
The test now validates netconsole functionality across both IP versions,
improving test coverage for dual-stack network environments.

This test suite validates the functionality of the devlink-rate API for
traffic class (TC) bandwidth allocation. It ensures that bandwidth can
be distributed between different traffic classes as configured, and
verifies that explicit TC-to-queue mapping is required for the
allocation to be effective.
The first test (test_no_tc_mapping_bandwidth) is marked as expected
failure on mlx5, since the hardware automatically enforces traffic
class separation by dynamically moving queues to the correct TC
scheduler, even without explicit TC-to-queue mapping configuration.
Test output on mlx5:

Zerocopy skbs are converted to regular copy skbs when data is queued
to a local socket. This happens in the existing test with a sender and
receiver communicating over a veth device.
Zerocopy skbs are sent without copying if egressing a device. Verify
that this behavior is maintained even in the common container setup
where data is forwarded over a veth to the physical device.
Update msg_zerocopy.sh to
1. Have a dummy network device to simulate a physical device.
2. Have forwarding enabled between veth and dummy.
3. Add a tx-only test that sends out dummy via the forwarding path.
4. Verify the exitcode of the sender, which signals zerocopy success.
As dummy drops all packets, this cannot be a TCP connection. Test
the new case with unconnected UDP only.
Update msg_zerocopy.c to
- Accept an argument whether send with zerocopy is expected.
- Return an exitcode whether behavior matched that expectation.

Note that this test may not fail in a kernel without the fix, but it may
hang on the client side if it triggers a kernel oops.
This works by creating a socket, trying to connect to a server, and then
executing a second connect operation on the same socket but to a
different CID (0). This triggers a transport change. If the connect
operation is interrupted by a signal, this could cause a null-ptr-deref.
Since this bug is non-deterministic, we need to try several times. It
is reasonable to assume that the bug will show up within the timeout
period.
If there is a G2H transport loaded in the system, the bug is not
triggered and this test will always pass. This is because
`vsock_assign_transport`, when using CID 0, like in this case, sets
vsk->transport to `transport_g2h` that is not NULL if a G2H transport is
available.

Test DSACK behavior with non contiguous ranges.
Without prior fix (tcp: fix tcp_ofo_queue() to avoid including
too much DUP SACK range) this would fail with:
tcp_dsack_mult.pkt:37: error handling packet: bad value outbound TCP option 5
script packet: 0.100682 . 1:1(0) ack 6001 <nop,nop,sack 1001:3001 7001:8001>
actual packet: 0.100679 . 1:1(0) ack 6001 win 1097 <nop,nop,sack 1001:6001 7001:8001>

Pull block fixes from Jens Axboe:
- Fixes for ublk:
- fix C++ narrowing warnings in the uapi header
- update/improve UBLK_F_SUPPORT_ZERO_COPY comment in uapi header
- fix for the ublk ->queue_rqs() implementation, limiting a batch
to just the specific task AND ring
- ublk_get_data() error handling fix
- sanity check more arguments in ublk_ctrl_add_dev()
- selftest addition
- NVMe pull request via Christoph:
- reset delayed remove_work after reconnect

- Fix for a warning introduced in bdev_count_inflight_rw() in this
merge window
* tag 'block-6.16-20250626' of git://git.kernel.dk/linux:
block: fix false warning in bdev_count_inflight_rw()
ublk: sanity check add_dev input for underflow
nvme: fix atomic write size validation
nvme: refactor the atomic write unit detection
nvme: reset delayed remove_work after reconnect
ublk: setup ublk_io correctly in case of ublk_get_data() failure
ublk: update UBLK_F_SUPPORT_ZERO_COPY comment in UAPI header
ublk: fix narrowing warnings in UAPI header
selftests: ublk: don't take same backing file for more than one ublk devices
ublk: build batch from IOs in same io_ring_ctx and io task
setup_wait() takes an optional argument and then is called from the top
level of the test script. That confuses shellcheck, which thinks that maybe
the intention is to pass $1 of the script to the function, which is never
the case. To avoid having to annotate every single new test with a SC
disable, split the function in two: one that takes a mandatory argument,
and one that takes no argument at all.
Convert the two existing users of that optional argument, both in Spectrum
resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh
to not pass a now-unused argument.

pull-request: bpf-next 2025-06-27
We've added 6 non-merge commits during the last 8 day(s) which contain
a total of 6 files changed, 120 insertions(+), 20 deletions(-).
The main changes are:
1) Fix RCU usage in task_cls_state() for BPF programs using helpers like
bpf_get_cgroup_classid_curr() outside of networking, from Charalampos
Mitrodimas.
2) Fix a sockmap race between map_update and a pending workqueue from
an earlier map_delete freeing the old psock where both pointed to the
same psock->sk, from Jiayuan Chen.
3) Fix a data corruption issue when using bpf_msg_pop_data() in kTLS which
failed to recalculate the ciphertext length, also from Jiayuan Chen.
4) Remove xdp_redirect_map{,_err} trace events since they are unused and
also hide XDP trace events under CONFIG_BPF_SYSCALL, from Steven Rostedt.
