Subject: [PATCH v4 bpf-next 0/2] Add array support to btf_struct_access
Date: Thu, 7 Nov 2019 10:09:01 -0800 [thread overview]
Message-ID: <20191107180901.4097452-1-kafai@fb.com> (raw)
This series adds array support to btf_struct_access().
Please see individual patch for details.
v4:
- Avoid removing a useful comment from btf_struct_access()
- Add comments to clarify the "mtrue_end" naming and
how it may not always correspond to mtype/msize/moff.
v3:
- Fixed an interpreter issue that missed accounting
for insn->off
v2:
- Fix a divide-by-zero when there is empty array in
a struct (e.g. "__u8 __cloned_offset[0];" in skbuff)
- Add 'static' to a global var in prog_tests/kfree_skb.c
