Subject: [PATCH v2 bpf-next 0/3] libbpf: BTF typed dump cleanups
Date: Fri, 16 Jul 2021 23:46:54 +0100 [thread overview]
Message-ID: <1626475617-25984-1-git-send-email-alan.maguire@oracle.com> (raw)
Fix issues with libbpf BTF typed dump code. Patch 1 addresses handling
of unaligned data. Patch 2 fixes issues Andrii noticed when compiling
on ppc64le. Patch 3 simplifies typed dump by getting rid of allocation
of dump data structure which tracks dump state etc.
Changes since v1:
- Andrii suggested using a function instead of a macro for checking
alignment of data, and pointed out that we need to consider dump
ptr size versus native pointer size (patch 1)
Alan Maguire (3):
libbpf: clarify/fix unaligned data issues for btf typed dump
libbpf: fix compilation errors on ppc64le for btf dump typed data
libbpf: btf typed dump does not need to allocate dump data
