cpu_number exists only on Intel and aarch64, so skip the test involing
it on other arches. An alternative would be to replace it with an
exported non-ifdefed primitive-typed percpu variable from the common
code, but there appears to be none.

The header is no longer needed since the event_pipe implementation
was updated to rely on libbpf's perf_buffer. This makes bpftool free of
dependencies to perf files, and we can update the Makefile accordingly.

One of bpftool's object files depends on zlib. To make sure we do not
attempt to build that object when the library is not available, commit
d66fa3c70e59 ("tools: bpftool: add feature check for zlib") introduced a
feature check to detect whether zlib is present.
This check comes as a rule for which the target ("zdep") is a
nonexistent file (phony target), which means that the Makefile always
attempts to rebuild it. It is mostly harmless. However, one side effect
is that, on running again once bpftool is already built, make considers
that "something" (the recipe for zdep) was executed, and does not print
the usual message "make: Nothing to be done for 'all'", which is a
user-friendly indicator that the build went fine.

In bpftool's Makefile, libbpf has a FORCE dependency, to make sure we
rebuild it in case its source files changed. Let's instead make the
rebuild depend on the source files directly, through a call to the
"$(wildcard ...)" function. This avoids descending into libbpf's
directory if there is nothing to update.
Do the same for the bootstrap libbpf version.
This results in a slightly faster operation and less verbose output when
running make a second time in bpftool's directory.
Before:

... libbfd: [ on ]
... disassembler-four-args: [ on ]

... libbfd: [ on ]

... zlib: [ on ]

Other ways to clean up the output could be to pass the "-s" option, or
to redirect the output to >/dev/null, when calling make recursively to
descend into libbpf's directory. However, this would suppress some
useful output if something goes wrong during the build. A better
alternative would be to pass "--no-print-directory" to the recursive
make, but that would still leave us with some noise for
"install_headers". Skipping the descent into libbpf's directory if no
source file has changed works best, and seems the most logical option
overall.

We recently updated bpftool's Makefile to make it install the headers
from libbpf, instead of pulling them directly from libbpf's directory.
There is also an additional header, internal to libbpf, that needs be
installed. The way that bpftool's Makefile installs that particular
header is currently correct, but would break if we were to modify
$(LIBBPF_INTERNAL_HDRS) to make it point to more than one header.
Use a static pattern rule instead, so that the Makefile can withstand
the addition of other headers to install.
The objective is simply to make the Makefile more robust. It should
_not_ be read as an invitation to import more internal headers from
libbpf into bpftool.

Although relying on some definitions from the netlink.h and if_link.h
headers copied into tools/include/uapi/linux/, libbpf does not need
those headers to stay entirely up-to-date with their original versions,
and the warnings emitted by the Makefile when it detects a difference
are usually just noise. Let's remove those warnings.

Going forward, future generation systems can have more hierarchy
within the node/package level but currently we don't have any data source
encoding field in perf, which can be used to represent this level of data.
Add a new field called 'mem_hops' in the perf_mem_data_src structure
which can be used to represent intra-node/package or inter-node/off-package
details. This field is of size 3 bits where PERF_MEM_HOPS_{NA, 0..6} value
can be used to present different hop levels data.
Also add corresponding macros to define mem_hop field values
and shift value.
Currently we define macro for HOPS_0 which corresponds
to data coming from another core but same node.
Add functionality to represent mem_hop field data in
perf_mem__lvl_scnprintf function with the help of added string
array called mem_hops.
For ex: Encodings for mem_hops fields with L2 cache:
L2 - local L2
L2 | REMOTE | HOPS_0 - remote core, same node L2
Since with the addition of HOPS field, now remote can be used to
denote cache access from the same node but different core, a check
is added in the c2c_decode_stats function to set mrem only when HOPS
is zero along with set remote field.

In RHEL's gating selftests we've encountered memory corruption in the
uffd event test even with upstream kernel:

testing uffd-wp with pagemap (pgsize=2097152): done
testing events (fork, remap, remove): ERROR: nr 32427 memory corruption 0 1 (errno=0, line=963)
ERROR: faulting process failed (errno=0, line=1117)
It can be easily reproduced when global thp enabled, which is the
default for RHEL.
It's also known as a side effect of commit 0db282ba2c12 ("selftest: use
mmap instead of posix_memalign to allocate memory", 2021-07-23), which
is imho right itself on using mmap() to make sure the addresses will be
untagged even on arm.
The problem is, for each test we allocate buffers using two
allocate_area() calls. We assumed these two buffers won't affect each
other, however they could, because mmap() could have found that the two
buffers are near each other and having the same VMA flags, so they got
merged into one VMA.
It won't be a big problem if thp is not enabled, but when thp is
agressively enabled it means when initializing the src buffer it could
accidentally setup part of the dest buffer too when there's a shared THP
that overlaps the two regions. Then some of the dest buffer won't be
able to be trapped by userfaultfd missing mode, then it'll cause memory
corruption as described.
To fix it, do release_pages() after initializing the src buffer.
Since the previous two release_pages() calls are after
uffd_test_ctx_clear() which will unmap all the buffers anyway (which is
stronger than release pages; as unmap() also tear town pgtables), drop
them as they shouldn't really be anything useful.
We can mark the Fixes tag upon 0db282ba2c12 as it's reported to only
happen there, however the real "Fixes" IMHO should be 8ba6e8640844, as
before that commit we'll always do explicit release_pages() before
registration of uffd, and 8ba6e8640844 changed that logic by adding
extra unmap/map and we didn't release the pages at the right place.
Meanwhile I don't have a solid glue anyway on whether posix_memalign()
could always avoid triggering this bug, hence it's safer to attach this
fix to commit 8ba6e8640844.

Patch set [1] introduced BTF_KIND_TAG to allow tagging
declarations for struct/union, struct/union field, var, func
and func arguments and these tags will be encoded into
dwarf. They are also encoded to btf by llvm for the bpf target.
After BTF_KIND_TAG is introduced, we intended to use it
for kernel __user attributes. But kernel __user is actually
a type attribute. Upstream and internal discussion showed
it is not a good idea to mix declaration attribute and
type attribute. So we proposed to introduce btf_type_tag
as a type attribute and existing btf_tag renamed to
btf_decl_tag ([2]).
This patch renamed BTF_KIND_TAG to BTF_KIND_DECL_TAG and some
other declarations with *_tag to *_decl_tag to make it clear
the tag is for declaration. In the future, BTF_KIND_TYPE_TAG
might be introduced per [3].

The current default does not allowing additional subflows, mostly
as a safety restriction to avoid uncontrolled resource consumption
on busy servers.
Still the system admin and/or the application have to opt-in to
MPTCP explicitly. After that, they need to change (increase) the
default maximum number of additional subflows.
Let set that to reasonable default, and make end-users life easier.
Additionally we need to update some self-tests accordingly.

In `test_no_sockets` we don't expect any sockets, indeed
check_no_sockets() prints an error and exits if `sockets` list is
not empty, so free_sock_stat() call is unnecessary since it would
only be called when the `sockets` list is empty.
This was discovered by a strange warning printed by gcc v11.2.1:
In file included from ../../include/linux/list.h:7,
from vsock_diag_test.c:18:
vsock_diag_test.c: In function ‘test_no_sockets’:

It seems related to some compiler optimization and assumption
about the empty `sockets` list, since this warning is printed
only with -02 or -O3. Also removing `exit(1)` from
check_no_sockets() makes the warning disappear since in that
case free_sock_stat() can be reached also when the list is
not empty.

Test that applications binding listening sockets to VRFs without
specifying TCP_MD5SIG_FLAG_IFINDEX will work as expected. This would
be broken if __tcp_md5_do_lookup always made a strict comparison on
l3index. See this email:
https://lore.kernel.org/netdev/209548b5-27d2-2059-f2e9-2148f5a0291b@gmail.com/
Applications using tcp_l3mdev_accept=1 and a single global socket (not
bound to any interface) also should have a way to specify keys that are
only for the default VRF, this is done by --force-bind-key-ifindex
without otherwise binding to a device.

Do this by converting to getopt_long because nettest has too many

The `cpu` argument of perf_evsel__read() must specify the cpu index.
perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index)
and is thus not appropriate for use with perf_evsel__read().
So, if there is an offline CPU, the cpu number specified in the argument
may point out of range because the cpu number and the cpu index are
different.
Fix test_stat_cpu().

Print offset of PERF_RECORD_COMPRESSED record instead of zero for
decompressed records in raw trace dump (-D option of perf-report):
0x17cf08 [0x28]: event: 9
instead of:
0 [0x28]: event: 9
The fix is not critical, because currently file_pos for compressed
events is used in perf_session__process_event only to show offsets
in the raw dump.

Add do_mark_test(), which is to do_ecn_test() like do_drop_test() is to
do_red_test(): meant to test that actions on the RED mark qevent block are
offloaded, and executed on ECN-marked packets.
The test splits install_qdisc() into its constituents, install_root_qdisc()
and install_qdisc_tcX(). This is in order to test that when mirroring is
enabled on one TC, the other TC does not mirror.

Add a test case that demonstrates port shadowing via UDP.
ns2 sends packet to ns1, from source port used by a udp service on the
router, ns0. Then, ns1 sends packet to ns0:service, but that ends up getting
forwarded to ns2.
Also add three test cases that demonstrate mitigations:
1. disable use of $port as source from 'unstrusted' origin
2. make the service untracked. This prevents masquerade entries
from having any effects.
3. add forced PAT via 'random' mode to translate the "wrong" sport
into an acceptable range.

The verifier tests added in commit c48e51c8b07a ("bpf: selftests: Add
selftests for module kfunc support") fail on s390, since the JIT does
not support calling kernel functions. This is most likely an issue for
all the other non-Intel arches, as well as on Intel with
!CONFIG_DEBUG_INFO_BTF or !CONFIG_BPF_JIT.
Trying to check for messages from all the possible add_kfunc_call()
failure cases in test_verifier looks pointless, so do a much simpler
thing instead: just like it's already done in do_prog_test_run(), skip
the tests that fail to load with ENOTSUPP.
