With latest llvm16, I got the following compilation error:
|
|
||||||
/.../src/cc/bpf_module.cc: In member function ‘void ebpf::BPFModule::dump_ir(llvm::Module&)’:
|
|
||||||
/.../src/cc/bpf_module.cc:259:15: error: ‘PrintModulePass’ was not declared in this scope

MPM.addPass(PrintModulePass(errs()));
|
|
||||||
^~~~~~~~~~~~~~~
|
|
||||||
...
|
|
||||||
|
|
||||||
The error is due to the llvm patch https://reviews.llvm.org/D138081.
|
|
||||||
Fix the issue by adjust corresponding header file locaiton
|
|
||||||
as in the above llvm patch.

Subject: [PATCH 1/2] Fix a llvm signed division error for compactsnoop tool
|
|
||||||
|
|
||||||
Fix issue #4182.
|
|
||||||
llvm doesn't support signed division and an assertion error
|
|
||||||
will happen when the IR contains sdiv. The reason is
|
|
||||||
due to code
|
|
||||||
zone - zone_pgdat->node_zones
|
|
||||||
where zone and zone_pgdat->node_zones are pointers to
|
|
||||||
struct zone (with size 1664). So effectively the above
|
|
||||||
is equivalent to
|
|
||||||
((void *)zone - (void *)zone_pgdat->node_zones)/sizeof(struct zone)
|
|
||||||
which is converted to sdiv insn.
|
|
||||||
llvm11 seems okay and I didn't investigate why. But llvm14 and
|
|
||||||
latest llvm16 failed with compiler fatal error.
|
|
||||||
|
|
||||||
To fix the issue let us replace the above '(void *)' as
|
|
||||||
'(u64)' and then the udiv will be used for the division.

Subject: [PATCH 1/2] Fix bpf_pseudo_fd() type conversion error
|
|
||||||
|
|
||||||
With llvm15 and llvm16, the following command line
|
|
||||||
sudo ./trace.py 'smp_call_function_single "%K", arg1'
|
|
||||||
will cause error:
|
|
||||||

|
||||||

^~~~~~~~~~~~~~~~~~~~

|
||||||
1 error generated.
|
|
||||||
Failed to compile BPF module <text>
|
|
||||||
|
|
||||||
In helpers.h, we have
|
|
||||||
u64 bpf_pseudo_fd(u64, u64) asm("llvm.bpf.pseudo");
|
|
||||||
Apparently, <= llvm14 can tolerate u64 -> 'void *' conversion, but
|
|
||||||
llvm15 by default will cause an error.
|
|
||||||
|
|
||||||
Let us explicitly convert bpf_pseudo_fd to 'void *' to avoid
|
|
||||||
such errors.

Subject: [PATCH 2/2] Fix clang 15 int to pointer conversion errors
|
|
||||||
|
|
||||||
Since version 15, clang issues error for implicit conversion of
|
|

integer to pointer. Several tools are broken. This patch add explicit
|
|
||||||
pointer cast where needed.
|
|
||||||

Subject: [PATCH] Fix get_kprobe_functions
|
|
||||||
|
|
||||||
get_kprobe_functions will not only return a function that matches the
|
|
||||||
regular expression, but also any function that starts with a
|
|
||||||
substrings that matches it. This is obviously not the intended
|
|
||||||
behavior.
|
|
||||||
The issue is easily fixed by replacing re.match by re.fullmatch.

Subject: [PATCH] RHEL: libbpf version fixes
|
|
||||||
|
|
||||||
Revert "[bcc] stop using deprecated `bpf_load_program_attr`"
|
|
||||||
Revert "backport `struct bpf_create_map_attr`"
|
|
||||||
Revert "bcc: Replace deprecated libbpf API"
|
|
||||||
|
|
||||||
Revert "bcc: Replace deprecated libbpf APIs" since the libbpf version
|
|
||||||
provided in RHEL 8 doesn't provide the new APIs.
|
|
||||||
|
|
||||||
Remove BPF_MAP_TYPE_BLOOM_FILTER from bps since the libbpf version in
|
|
||||||
RHEL 8, doesn't provide bloom filter map.
|
|
||||||
|
|
||||||
Rename btf__load_vmlinux_btf into libbpf_find_kernel_btf. The function
|
|
||||||
has been renamed upstream for naming consistency, but RHEL 8 libbpf
|
|
||||||
still uses the old name.
|
|
||||||
|
|
||||||
Also use the older btf__get_nr_types() instead of btf__type_cnt() for
|
|
||||||
the same reason.
|
|
||||||
|
|
||||||
Add definition of struct bpf_core_relo.

|

Subject: [PATCH 3/3] libbpf: Allow kernel_struct_has_field to reach field in
|
|
||||||
unnamed struct or union
|
|
||||||
|
|
||||||
Some fields can belong to unnamed struct or union (e.g. rcu and
|
|
||||||
rcu_users fields of task_struct). In C, they are accessed as if their
|
|
||||||
belong directly to the parent of the unnamed struct or union but this
|
|
||||||
is not the case for BTF.
|
|
||||||
|
|
||||||
When looking for a field, kernel_struct_has_field should also look
|
|
||||||
reccursively into unnamed structs or unions. That allows code such as
|
|
||||||
the following to work as expected:
|
|
||||||
|
|
||||||
BPF.kernel_struct_has_field('task_struct', 'rcu')

Subject: [PATCH 2/2] tools/compactsnoop.py: Fix raw_tracepoint Invalid

||||||
argument error
|
|
||||||
|
|
||||||
kernel commit abd4349ff9b8("mm: compaction: cleanup the compaction trace
|
|
||||||
events") change the arguments of 'mm_compaction_begin' from (start_pfn,
|
|
||||||
migrate_pfn, free_pfn, end_pfn, sync) to (cc, start_pfn, end_pfn, sync),
|
|
||||||
and change the arguments of 'mm_compaction_end' from (start_pfn,
|
|
||||||
migrate_pfn, free_pfn, end_pfn, sync, ret) to (cc, start_pfn, end_pfn,
|
|
||||||
sync, ret).
|
|
||||||
|
|
||||||
Replacing RAW_TRACEPOINT_PROBE with TRACEPOINT_PROBE solves this problem
|
|
||||||
and guarantees compatibility.

Subject: [PATCH 2/3] tools/tcpstates: fix IPv6 journal
|
|
||||||
|
|
||||||
When logging ipv6 state change, journal_fields tries to pack
|
|
||||||
event.addr and event.daddr, which is not an integer in this, to
|
|
||||||
present a bytes-like object to socket.inet_ntop. This can be fixed by
|
|
||||||
having a similar type for [sd]addr for IPv4 and IPv6. Making both an
|
|
||||||
array of u32 solves the issue by presenting a bytes-like object
|
|
||||||
directly to inet_ntop, without the need for the struct packing stage.
|
|
||||||
|
|
||||||
Also now, the similar behavior, makes it easier to factor code for
|
|
||||||
IPv4 and IPv6.
|
|
||||||
|
|
||||||
It solves the following error:
|

||||||

Subject: [PATCH 1/3] tools/tcpstates: fix context ptr modified error
|
|
||||||
|
|
||||||
Introduce local variable tcp_new_state,
|
|
||||||
to avoid llvm optimization of args->newstate,
|
|
||||||
which will cause context ptr args modified.
|
|
||||||
spilt event.ports to lport and dport.
|
|
||||||
switch type of TCP state from unsigned int to int.
