Currently if a declaration appears in the BTF before the definition, the
definition is dumped as a conflicting name, eg:

    $ bpftool btf dump file vmlinux format raw | grep "'unix_sock'"
    [81287] FWD 'unix_sock' fwd_kind=struct
    [89336] STRUCT 'unix_sock' size=1024 vlen=14

    $ bpftool btf dump file vmlinux format c | grep "struct unix_sock"
    struct unix_sock;
    struct unix_sock___2 {	<--- conflict, the "___2" is unexpected
		    struct unix_sock___2 *unix_sk;

This causes a compilation error if the dump output is used as a header
file.

Fix it by skipping declaration when counting duplicated type names.

When opened a symlink, link name is from 'inode->i_link', but it may be
reset to a new value when revalidate the dentry. If some processes get the
link name on the race scenario, then UAF will happen on link name.

Fix this by implementing 'get_link' interface to duplicate the link name.

With latest upstream llvm18, the following test cases failed:

  #13/3    bpf_cookie/multi_kprobe_attach_api:FAIL

  #356/17  test_global_funcs/global_func17:FAIL
  #356     test_global_funcs:FAIL

Further analysis shows llvm upstream patch [1] is responsible
for the above failures. For example, for function bpf_fentry_test7()
in net/bpf/test_run.c, without [1], the asm code is:
  0000000000000400 <bpf_fentry_test7>:
     400: f3 0f 1e fa                   endbr64

     40c: c3                            retq
     40d: 0f 1f 00                      nopl    (%rax)
and with [1], the asm code is:
  0000000000005d20 <bpf_fentry_test7.specialized.1>:
    5d20: e8 00 00 00 00                callq   0x5d25 <bpf_fentry_test7.specialized.1+0x5>
    5d25: c3                            retq
and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7>
and this caused test failures for #13/#77 etc. except #356.

For test case #356/17, with [1] (progs/test_global_func17.c)),
the main prog looks like:
  0000000000000000 <global_func17>:
       0:       b4 00 00 00 2a 00 00 00 w0 = 0x2a
       1:       95 00 00 00 00 00 00 00 exit
which passed verification while the test itself expects a verification
failure.

Let us add 'barrier_var' style asm code in both places to prevent
function specialization which caused selftests failure.

Erhard reported that the 6.7-rc1 kernel panics on boot if being
built with clang-16. The problem was not reproducible with gcc.

[    6.027000] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

Actually the problem is caused by uninitialized local variable in
current_obj_cgroup().  If the root memory cgroup is set as an active
memory cgroup for a charging scope (as in the trace, where systemd tries
to create the first non-root cgroup, so the parent cgroup is the root
cgroup), the "for" loop is skipped and uninitialized objcg is returned,
causing a panic down the accounting stack.

The fix is trivial: initialize the objcg variable to NULL unconditionally
before the "for" loop.

Add 3 test cases for skb dynptr used in tp_btf:
- test_dynptr_skb_tp_btf: use skb dynptr in tp_btf and make sure it is
  read-only.
- skb_invalid_ctx_fentry/skb_invalid_ctx_fexit: bpf_dynptr_from_skb
  should fail in fentry/fexit.

In test_dynptr_skb_tp_btf, to trigger the tracepoint in kfree_skb,
test_pkt_access is used for its test_run, as in kfree_skb.c. Because the
test process is different from others, a new setup type is defined,
i.e., SETUP_SKB_PROG_TP.

The result is like:
$ ./test_progs -t 'dynptr/test_dynptr_skb_tp_btf'
  #77/14   dynptr/test_dynptr_skb_tp_btf:OK
  #77      dynptr:OK
  #120     kfunc_dynptr_param:OK
  Summary: 2/1 PASSED, 0 SKIPPED, 0 FAILED

Add 3 test cases for skb dynptr used in tp_btf:
- test_dynptr_skb_tp_btf: use skb dynptr in tp_btf and make sure it is
  read-only.
- skb_invalid_ctx_fentry/skb_invalid_ctx_fexit: bpf_dynptr_from_skb
  should fail in fentry/fexit.

In test_dynptr_skb_tp_btf, to trigger the tracepoint in kfree_skb,
test_pkt_access is used for its test_run, as in kfree_skb.c. Because the
test process is different from others, a new setup type is defined,
i.e., SETUP_SKB_PROG_TP.

The result is like:
$ ./test_progs -t 'dynptr/test_dynptr_skb_tp_btf'
  #77/14   dynptr/test_dynptr_skb_tp_btf:OK
  #77      dynptr:OK
  #120     kfunc_dynptr_param:OK
  Summary: 2/1 PASSED, 0 SKIPPED, 0 FAILED

Add the following ./test_progs tests:

  * atomics/load_acquire
  * atomics/store_release
  * arena_atomics/load_acquire
  * arena_atomics/store_release

They depend on the pre-defined __BPF_FEATURE_LOAD_ACQ_STORE_REL feature
macro, which implies -mcpu>=v4.

  $ ALLOWLIST=atomics/load_acquire,atomics/store_release,
  $ ALLOWLIST+=arena_atomics/load_acquire,arena_atomics/store_release

</TASK>

The fuzz image has a truncate log inode whose tl_count is bigger than
ocfs2_truncate_recs_per_inode() so it triggers the BUG in
ocfs2_truncate_log_append().

As what the check in ocfs2_truncate_log_append() does, just do same check
into ocfs2_get_truncate_log_info when truncate log inode is reading in so
we can bail out earlier.
