Subject: [PATCH bpf-next v2 0/7] bpf: remove bpf_load loader completely
Date: Thu, 19 Nov 2020 15:06:10 +0000 [thread overview]
Message-ID: <20201119150617.92010-1-danieltimlee@gmail.com> (raw)
Numerous refactoring that rewrites BPF programs written with bpf_load
to use the libbpf loader was finally completed, resulting in BPF
programs using bpf_load within the kernel being completely no longer
present.
This patchset refactors remaining bpf programs with libbpf and
completely removes bpf_load, an outdated bpf loader that is difficult
to keep up with the latest kernel BPF and causes confusion.
Changes in v2:
- drop 'move tracing helpers to trace_helper' patch
- add link pinning to prevent cleaning up on process exit
- add static at global variable and remove unused variable
- change to destroy link even after link__pin()
- fix return error code on exit
- merge commit with changing Makefile
