This kunit update for Linux 5.11-rc3 consists one fix to force the use
of the 'tty' console for UML. Given that kunit tool requires the console
output, explicitly stating the dependency makes sense than relying on
it being the default.

It's not conventional C to put non-inline functions in header
files. Create a source file for the functions instead. Also
reduce the amount of globals and rename the functions to
something less generic.

Adds new 2 new tests to the PTMU script: pmtu_ipv4/6_route_change.
These tests explicitly test for a recently discovered problem in the
IPv6 routing framework where PMTU exceptions were not properly released
when replacing a route via "ip route change ...".
After creating PMTU exceptions, the route from the device A to R1 will be
replaced with a new route, then device A will be deleted. If the PMTU
exceptions were properly cleaned up by the kernel, this device deletion
will succeed. Otherwise, the unregistration of the device will stall, and
messages such as the following will be logged in dmesg:
unregister_netdevice: waiting for veth_A-R1 to become free. Usage count = 4

For older glibc ~2.17, #include'ing both linux/if.h and net/if.h
fails due to complaints about redefinition of interface flags:
CC net.o
In file included from net.c:13:0:
/usr/include/linux/if.h:71:2: error: redeclaration of enumerator ‘IFF_UP’
IFF_UP = 1<<0, /* sysfs */
^
/usr/include/net/if.h:44:5: note: previous definition of ‘IFF_UP’ was here
IFF_UP = 0x1, /* Interface is up. */
The issue was fixed in kernel headers in [1], but since compilation
of net.c picks up system headers the problem can recur.
Dropping #include <linux/if.h> resolves the issue and it is
not needed for compilation anyhow.

The kernel image can contain multiple types (structs/unions)
with the same name. This causes distinct type hierarchies in
BTF data and makes resolve_btfids fail with error like:
BTFIDS vmlinux
FAILED unresolved symbol udp6_sock
as reported by Qais Yousef [1].
This change adds warning when multiple types of the same name
are detected:
BTFIDS vmlinux
WARN: multiple IDs found for 'file': 526, 113351 - using 526
WARN: multiple IDs found for 'sk_buff': 2744, 113958 - using 2744
We keep the lower ID for the given type instance and let the
build continue.
Also changing the 'nr' variable name to 'nr_types' to avoid confusion.

The udpgro.sh will always return 0 (unless the bpf selftest was not

Therefore the kselftest framework will report this case is OK.

kunit_tool relies on the UML console outputting printk() output to the
tty in order to get results. Since the default console driver could
change, pass 'console=tty' to the kernel.
This is triggered by a change[1] to use ttynull as a fallback console
driver which -- by chance or by design -- seems to have changed the
default console output on UML, breaking kunit_tool. While this may be
fixed, we should be less fragile to such changes in the default.

Commit d8cbe8bfa7 ("tools/testing/selftests/vm: fix build error") tried
to include a ARCH check for powerpc, however ARCH is not defined in the
Makefile before including lib.mk. This makes test building to skip on
both x86 and powerpc.
Fix the arch check by replacing it using machine type as it is already
defined and used in the test.

When CONFIG_BPF_LSM is not configured, running bpf selftesting will show
BPF_F_BPRM_SECUREEXEC undefined error for bprm_opts.c.
The problem is that bprm_opts.c includes vmliunx.h. The vmlinux.h is
generated by "bpftool btf dump file ./vmlinux format c". On the other
hand, BPF_F_BPRM_SECUREEXEC is defined in include/uapi/linux/bpf.h
and used only in bpf_lsm.c. When CONFIG_BPF_LSM is not set, bpf_lsm
will not be compiled, so vmlinux.h will not include definition of
BPF_F_BPRM_SECUREEXEC.
Ideally, we want to compile bpf selftest regardless of the configuration
setting, so change the include file from vmlinux.h to bpf.h.

====================
pull-request: bpf 2020-12-28
The following pull-request contains BPF updates for your *net* tree.
There is a small merge conflict between bpf tree commit 69ca310f34
("bpf: Save correct stopping point in file seq iteration") and net tree
commit 66ed594409 ("bpf/task_iter: In task_file_seq_get_next use
task_lookup_next_fd_rcu"). The get_files_struct() does not exist anymore
in net, so take the hunk in HEAD and add the `info->tid = curr_tid` to
the error path:
[...]
curr_task = task_seq_get_next(ns, &curr_tid, true);
if (!curr_task) {
info->task = NULL;
info->tid = curr_tid;
return NULL;
}
/* set info->task and info->tid */
[...]
We've added 10 non-merge commits during the last 9 day(s) which contain
a total of 11 files changed, 75 insertions(+), 20 deletions(-).
The main changes are:
1) Various AF_XDP fixes such as fill/completion ring leak on failed bind and
fixing a race in skb mode's backpressure mechanism, from Magnus Karlsson.
2) Fix latency spikes on lockdep enabled kernels by adding a rescheduling
point to BPF hashtab initialization, from Eric Dumazet.
3) Fix a splat in task iterator by saving the correct stopping point in the
seq file iteration, from Jonathan Lemon.
4) Fix BPF maps selftest by adding retries in case hashtab returns EBUSY
errors on update/deletes, from Andrii Nakryiko.
5) Fix BPF selftest error reporting to something more user friendly if the
vmlinux BTF cannot be found, from Kamal Mostafa.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The argv_split() function must be paired with argv_free(), else we must
keep a reference to the argv array received or do the freeing ourselves,
in synthesize_sdt_probe_command() we were simply leaking that argv[]
array.

A separate field isn't strictly required. The core field could be
re-used for thread IDs as a single field was used previously.
But separating them will avoid confusion and catch potential errors
where core IDs are read as thread IDs and vice versa.
Also remove the placeholder id field which is now no longer used.

Add socket as a separate member so that it doesn't have to be packed
into the int value.
When the socket ID was larger than 8 bits the output appeared corrupted
or incomplete.
For example, here on ThunderX2 'perf stat' reports a socket of -1 and an
invalid die number:
./perf stat -a --per-die
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255 128 687.99 msec cpu-clock # 57.240 CPUs utilized
...
S36-D0 128 842.34 msec cpu-clock # 70.081 CPUs utilized
...
And with --per-core there is an entry with an invalid core ID:
./perf stat record -a --per-core
The socket id number is too big.
Performance counter stats for 'system wide':
S-1-D255-C65535 128 671.04 msec cpu-clock # 54.112 CPUs utilized
...
S36-D0-C0 4 28.27 msec cpu-clock # 2.279 CPUs utilized
...
This fixes the "Session topology" self test on ThunderX2.
After this fix the output contains the correct socket and die IDs and no
longer prints a warning about the size of the socket ID:
./perf stat --per-die -a
Performance counter stats for 'system wide':
S36-D0 128 169,869.39 msec cpu-clock # 127.501 CPUs utilized

Use the existing allocator for perf_cpu_map to avoid use of raw malloc.
This could cause an issue in later commits where the size of
perf_cpu_map is changed.

prefixed ones to catch this new AMD64_VM_PAGE_FLUSH MSR.
