Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Update copies of kernel headers, which resulted in support for the
   new 'mseal' syscall, SUBVOL statx return mask bit, RISC-V and PPC
   prctls, fcntl's DUPFD_QUERY, POSTED_MSI_NOTIFICATION IRQ vector,
   'map_shadow_stack' syscall for x86-32.

 - Revert perf.data record memory allocation optimization that ended up
   causing a regression, work is being done to re-introduce it in the
   next merge window.

 - Fix handling of minimal vmlinux.h file used with BPF's CO-RE when
   interrupting the build.

Without this, the 'i' variable declared before could be overridden by
accident, e.g.

  for i in "${@}"; do
      __ksft_status_merge "${i}"  ## 'i' has been modified
      foo "${i}"                  ## using 'i' with an unexpected value
  done

After a quick look, it looks like 'i' is currently not used after having
been modified in __ksft_status_merge(), but still, better be safe than
sorry. I saw this while modifying the same file, not because I suspected
an issue somewhere.

If there is an error to create the first netns with 'setup_ns()',
'cleanup_ns()' will be called with an empty string as first parameter.

The consequences is that 'cleanup_ns()' will try to delete an invalid
netns, and wait 20 seconds if the netns list is empty.

Instead of just checking if the name is not empty, convert the string
separated by spaces to an array. Manipulating the array is cleaner, and
calling 'cleanup_ns()' with an empty array will be a no-op.

If errexit is enabled ('set -e'), loopy_wait -- or busywait and others
using it -- will stop after the first failure.

Note that if the returned status of loopy_wait is checked, and even if
errexit is enabled, Bash will not stop at the first error.

pull-request: bpf 2024-06-05

We've added 8 non-merge commits during the last 6 day(s) which contain
a total of 9 files changed, 34 insertions(+), 35 deletions(-).

The main changes are:

1) Fix a potential use-after-free in bpf_link_free when the link uses
   dealloc_deferred to free the link object but later still tests for
   presence of link->ops->dealloc, from Cong Wang.

2) Fix BPF test infra to set the run context for rawtp test_run callback
   where syzbot reported a crash, from Jiri Olsa.

3) Fix bpf_session_cookie BTF_ID in the special_kfunc_set list to exclude
   it for the case of !CONFIG_FPROBE, also from Jiri Olsa.

4) Fix a Coverity static analysis report to not close() a link_fd of -1
   in the multi-uprobe feature detector, from Andrii Nakryiko.

5) Revert support for redirect to any xsk socket bound to the same umem
   as it can result in corrupted ring state which can lead to a crash when
   flushing rings. A different approach will be pursued for bpf-next to
   address it safely, from Magnus Karlsson.

6) Fix inet_csk_accept prototype in test_sk_storage_tracing.c which caused
   BPF CI failure after the last tree fast forwarding, from Andrii Nakryiko.

7) Fix a coccicheck warning in BPF devmap that iterator variable cannot
   be NULL, from Thorsten Blum.

Let's test that we can have shared zeropages in our process as long as
storage keys are not getting used, that shared zeropages are properly
unshared (replaced by anonymous pages) once storage keys are enabled,
and that no new shared zeropages are populated after storage keys
were enabled.

We require the new pagemap interface to detect the shared zeropage.

On an old kernel (zeropages always disabled):
	# ./s390x/shared_zeropage_test
	TAP version 13
	1..3
	not ok 1 Shared zeropages should be enabled
	ok 2 Shared zeropage should be gone
	ok 3 Shared zeropages should be disabled
	# Totals: pass:2 fail:1 xfail:0 xpass:0 skip:0 error:0

On a fixed kernel:
	# ./s390x/shared_zeropage_test
	TAP version 13
	1..3
	ok 1 Shared zeropages should be enabled
	ok 2 Shared zeropage should be gone
	ok 3 Shared zeropages should be disabled
	# Totals: pass:3 fail:0 xfail:0 xpass:0 skip:0 error:0

Testing of UFFDIO_ZEROPAGE can be added later.

Ingo reported that he was seeing these when hitting Control+C during a
perf tools build:

  Makefile.perf:1149: *** Missing bpftool input for generating vmlinux.h. Stop.

The failure happens when you don't have vmlinux.h or vmlinux with BTF.

ifeq ($(VMLINUX_H),)
  ifeq ($(VMLINUX_BTF),)
    $(error Missing bpftool input for generating vmlinux.h)
  endif
endif

VMLINUX_BTF can be empty if you didn't build a kernel or it doesn't have
a BTF section and the current kernel also has no BTF.  This is totally
ok.

But VMLINUX_H should be set to the minimal version in the source tree
(unless you overwrite it manually) when you don't pass GEN_VMLINUX_H=1
(which requires VMLINUX_BTF should not be empty).  The problem is that
it's defined in Makefile.config which is not included for `make clean`.
