Subject: [PATCH,bpf-next v2 0/2] Fix broken samples due to symbol mismatch
Date: Thu, 5 Dec 2019 17:01:12 +0900 [thread overview]
Message-ID: <20191205080114.19766-1-danieltimlee@gmail.com> (raw)
Currently, there are broken samples due to symbol mismatch (missing or
unused symbols). For example, the function open() calls the syscall
'sys_openat' instead of 'sys_open'. And there are no exact symbols such
as 'sys_read' or 'sys_write' under kallsyms, instead the symbols have
prefixes. And these error leads to broke of samples.
This Patchset fixes the problem by changing the symbol match.
Changes in v2:
- remove redundant casting
Daniel T. Lee (2):
samples: bpf: replace symbol compare of trace_event
samples: bpf: fix syscall_tp due to unused syscall
