b344a48cbe selftests: drv: net: fix test failure on ipv6 sys
The `get_interface_info` call has ip version hard-coded which leads to
failures on an IPV6 system. The NetDrvEnv class already gathers
information about remote interface, so instead of fixing the local
implementation switch to using cfg.remote_ifname.

Before:
./drivers/net/ping.py
Traceback (most recent call last):

  File "/new_tests/./drivers/net/ping.py", line 128, in get_interface_info
    raise KsftFailEx('Can not get remote interface')

b6a6006b0e selftests: Add IPv6 link-local address generation tests for GRE devices.
GRE devices have their special code for IPv6 link-local address
generation that has been the source of several regressions in the past.

Add selftest to check that all gre, ip6gre, gretap and ip6gretap get an
IPv6 link-link local address in accordance with the
net.ipv6.conf.<dev>.addr_gen_mode sysctl.

Note: This patch was originally applied as commit 6f50175cca ("selftests:
  Add IPv6 link-local address generation tests for GRE devices.").
  However, it was then reverted by commit 355d940f4d ("Revert "selftests:
  Add IPv6 link-local address generation tests for GRE devices."")
  because the commit it depended on was going to be reverted. Now that
  the situation is resolved, we can add this selftest again (no changes
  since original patch, appart from context update in
  tools/testing/selftests/net/Makefile).

c7ac7452df selftests: mptcp: add helpers to get subflow_info
This patch adds 'get_subflow_info' in 'mptcp_diag', which can check whether
a TCP connection is an MPTCP subflow based on the "INET_ULP_INFO_MPTCP"
with tcp_diag method.

The helper 'print_subflow_info' in 'mptcp_diag' can print the subflow_filed
of an MPTCP subflow for further checking the 'subflow_info' through
inet_diag method.

The example of the whole output should be:

  $ ./mptcp_diag -s "127.0.0.1:10000 127.0.0.1:38984"
  127.0.0.1:10000 -> 127.0.0.1:38984
  It's a mptcp subflow, the subflow info:
   flags:Mec token:0000(id:0)/4278e77e(id:0) seq:9288466187236176036 \
   sfseq:1 ssnoff:2317083055 maplen:215

caa6811cca selftests: mptcp: refactor NLMSG handling with 'proto'
This patch introduces the '__u32 proto' variable to the 'send_query' and
'recv_nlmsg' functions for further extending function.

In the 'send_query' function, the inclusion of this variable makes the
structure clearer and more readable.

In the 'recv_nlmsg' function, the '__u32 proto' variable ensures that
the 'diag_info' field remains unmodified when processing IPPROTO_TCP data,
thereby preventing unintended transformation into 'mptcp_info' format.

While at it, increment iovlen directly when an item is added to simplify
this portion of the code and improve its readaility.

6d0eb15c65 selftests: mptcp: info: hide 'grep: write error' warnings
mptcp_lib_get_info_value() will only print the first entry that match
the filter because of the ';q' at the end. As a consequence, the 'sed'
command could finish before the previous 'grep' one and print a 'write
error' warning because it is trying to write data to the closed pipe.

Such warnings are not interesting, they can be hidden by muting stderr
here for grep.

While at it, clearly indicate that mptcp_lib_get_info_value() will only
print the first matched entry to avoid confusions later on.

e371b9d336 selftests: ublk: kublk: fix include path
Building kublk currently fails (with a "could not find linux/ublk_cmd.h"
error message) if kernel headers are not installed in a system-global
location (i.e. somewhere in the compiler's default include search path).
This failure is unnecessary, as make kselftest installs kernel headers
in the build tree - kublk's build just isn't looking for them properly.
There is an include path in kublk's CFLAGS which is probably intended to
find the kernel headers installed in the build tree; fix it so that it
can actually find them.

This introduces some macro redefinition issues between glibc-provided
headers and kernel headers; fix those by eliminating one include in
kublk.

3d6ee575d0 selftests: ublk: kublk: build with -Werror iff WERROR!=0
Compiler warnings can catch bugs at compile time; thus, heeding them is
usually a good idea. Turn warnings into errors by default for the kublk
build so that anyone making changes is forced to heed them. Compiler
warnings can also sometimes produce annoying false positives, so provide
a flag WERROR that the developer can use as follows to have the build
and selftests run go through even if there are warnings:

The main changes are:

1) Avoid skipping or repeating a sk when using a UDP bpf_iter,
   from Jordan Rife.

2) Fixed a crash when a bpf qdisc is set in
   the net.core.default_qdisc, from Amery Hung.

3) A few other fixes in the bpf qdisc, from Amery Hung.
   - Always call qdisc_watchdog_init() in the .init prologue such that
     the .reset/.destroy epilogue can always call qdisc_watchdog_cancel()
     without issue.
   - bpf_qdisc_init_prologue() was incorrectly returning an error
     when the bpf qdisc is set as the default_qdisc and the mq is creating
     the default_qdisc. It is now fixed.

Test the basic functionality for the NUMA and MPOL flags:
- FUTEX2_NUMA should take the NUMA node which is after the uaddr
  and use it.
- Only update the node if FUTEX_NO_NODE was set by the user
- FUTEX2_MPOL should use the memory based on the policy. I attempted to
  set the node with mbind() and then use this with MPOL but this fails
  and futex falls back to the default node for the current CPU.

- The first thread initializes the private hash.
- More than four threads will increase the size of the private hash if
  the system has more than 16 CPUs online.
- Once the user sets the size of private hash, auto scaling is disabled.
- The user is only allowed to use numbers to the power of two.
- The user may request the global or make the hash immutable.
- Once the global hash has been set or the hash has been made immutable,
  further changes are not allowed.
- Futex operations should work the whole time. It must be possible to
  hold a lock, such a PI initialised mutex, during the resize operation.

c58dcc1dbe selftests/bpf: Add tests for bucket resume logic in UDP socket iterators
Introduce a set of tests that exercise various bucket resume scenarios:

* remove_seen resumes iteration after removing a socket from the bucket
  that we've already processed. Before, with the offset-based approach,
  this test would have skipped an unseen socket after resuming
  iteration. With the cookie-based approach, we now see all sockets
  exactly once.
* remove_unseen exercises the condition where the next socket that we
  would have seen is removed from the bucket before we resume iteration.
  This tests the scenario where we need to scan past the first cookie in
  our remembered cookies list to find the socket from which to resume
  iteration.
* remove_all exercises the condition where all sockets we remembered
  were removed from the bucket to make sure iteration terminates and
  returns no more results.
* add_some exercises the condition where a few, but not enough to
  trigger a realloc, sockets are added to the head of the current bucket
  between reads. Before, with the offset-based approach, this test would
  have repeated sockets we've already seen. With the cookie-based
  approach, we now see all sockets exactly once.
* force_realloc exercises the condition that we need to realloc the
  batch on a subsequent read, since more sockets than can be held in the
  current batch array were added to the current bucket. This exercies
  the logic inside bpf_iter_udp_realloc_batch that copies cookies into
  the new batch to make sure nothing is skipped or repeated.

f263336a41 selftests/bpf: Add btf dedup test covering module BTF dedup
Recently issues were observed with module BTF deduplication failures
[1].  Add a dedup selftest that ensures that core kernel types are
referenced from split BTF as base BTF types.  To do this use bpf_testmod
functions which utilize core kernel types, specifically

ssize_t
bpf_testmod_test_write(struct file *file, struct kobject *kobj,
                       struct bin_attribute *bin_attr,
                       char *buf, loff_t off, size_t len);

__bpf_kfunc struct sock *bpf_kfunc_call_test3(struct sock *sk);

__bpf_kfunc void bpf_kfunc_call_test_pass_ctx(struct __sk_buff *skb);

For each of these ensure that the types they reference -
struct file, struct kobject, struct bin_attr etc - are in base BTF.
Note that because bpf_testmod.ko is built with distilled base BTF
the associated reference types - i.e. the PTR that points at a
"struct file" - will be in split BTF.  As a result the test resolves
typedef and pointer references and verifies the pointed-at or
typedef'ed type is in base BTF.  Because we use BTF from
/sys/kernel/btf/bpf_testmod relocation has occurred for the
referenced types and they will be base - not distilled base - types.

For large-scale dedup issues, we see such types appear in split BTF and
as a result this test fails.  Hence it is proposed as a test which will
fail when large-scale dedup issues have occurred.
