In the forwarding testcase, it opens a server and a client with the nc.
The server receives the correct message from NC, it prints OK.
The server prints FAIL if it receives the wrong message from the client.
But If the server can't receive any message, it will not close so

Add a simple test for the epoll busy poll ioctls, using the kernel
selftest harness.
This test ensures that the ioctls have the expected return codes and
that the kernel properly gets and sets epoll busy poll parameters.
The test can be expanded in the future to do real busy polling (provided

Hi, all,
With the latest 6.9-rc7 torvalds tree kernel, the "make kselftest"
always hangs in the following
./pidfd_setns_test.
Symptoms are that all ./pidfd_netne_test processes end up in pause()
syscalls, with
nothing to wake them up.
Please find the config attached. All the options from the

Now that we have updated userfaultfd_api to correctly return
EIVAL when a feature is requested but not available, let's fix
the uffd-stress test to only set the UFFD_FEATURE_WP_UNPOPULATED
feature when the config is set. In addition, still run the test if
the CONFIG_PTE_MARKER_UFFD_WP is not set,
Currently if we request a feature that is not set in the Kernel
config we fail silently and return the available features. However, the
documentation indicates we should return an EINVAL.
We need to fix this issue since we can end up with a Kernel warning
should a program request the feature

{inet,ipv6}_gro_receive functions perform flush checks (ttl, flags,
iph->id, ...) against all packets in a loop. These flush checks are used in
all merging UDP and TCP flows.
These checks need to be done only once and only against the found p skb,
since they only affect flush and not same_flow.
This patch converts references of skb->network_header to napi_gro_cb's
network_offset and inner_network_offset.

The cb fields network_offset and inner_network_offset are used instead of

These fields are then leveraged in the next commit to remove flush_id state

This binary covers multiple scenarios, based on arguments given,
for both IPv4 and IPv6:
- Accept UDP correct checksum
- Detect UDP invalid checksum
- Accept TCP correct checksum

Add several new test cases which assert corner cases on the eventfd
mechanism, for example, the supplied buffer is less than 8 bytes,
attempting to write a value that is too large, etc.

And then cleanup the verifier about the special cases about this kfunc.

This allows kfunc to request the prog_aux environment in their
implementation, to have access to the originated bpf_prog for example.

It looks like the generic implementation based on __s_async suffix works
well enough. So let's use it.
Note:
- currently we lose the return value range
- the second argument is not of type PTR_TO_MAP_KEY

There is no change of behavior: for each kfunc, we store the prog
sleepable state. But this allows to declare an async non sleepable
callback from a syscall, where everything is sleepable.

This patch adds a subtest named test_subflow to load and verify the newly
added mptcp subflow example in test_mptcp. Add a helper endpoint_init()

Move Nicolas's patch into bpf selftests directory. This example added a
test that was adding a different mark (SO_MARK) on each subflow, and
changing the TCP CC only on the first subflow.
This example shows how it is possible to:

It's necessary to delete netns during the MPTCP bpf tests interrupt,
otherwise the next tests run will fail due to unable to create netns.

In this series from Geliang, modifying MPTCP BPF selftests, we have:
- SIGINT support
- A new macro to reduce duplicated code
- A new MPTCP subflow BPF program setting socket options per subflow: it
looks better to have this old test program in the BPF selftests to
track regressions and to
Without this change the created netns instances are not cleared after
this script execution. To fix this problem the cleanup_all_ns function
