Merge branch 'bpf: Fixes for kprobe multi on kernel modules'
Jiri Olsa says:
====================
hi,
Martynas reported kprobe _multi link does not resolve symbols
from kernel modules, which attach by address works.
In addition while fixing that I realized we do not take module
reference if the module has kprobe_multi link on top of it and
can be removed.
There's mo crash related to this, it will silently disappear from
ftrace tables, while kprobe_multi link stays up with no data.
This patchset has fixes for both issues.
v3 changes:
- reorder fields in struct bpf_kprobe_multi_link [Andrii]
- added ack [Andrii]
v2 changes:
- added acks (Song)
- added comment to kallsyms_callback (Song)
- change module_callback realloc logic (Andrii)
- get rid of macros in tests (Andrii)
thanks,
jirka
