Subject: [PATCH 11/77] perf trace: Add a etcsnoop.c augmented syscalls eBPF utility
Date: Wed, 5 Sep 2018 19:03:34 -0300 [thread overview]
Message-ID: <20180905220440.20256-12-acme@kernel.org> (raw)
In-Reply-To: <20180905220440.20256-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
We need to put common stuff into a separate header in tools/perf/include/bpf/
for these augmented syscalls, but I couldn't resist adding a etcsnoop.c tool,
combining augmented syscalls + filtering, that in the future will be passed
from 'perf trace''s command line, to use in building the eBPF program to do
that specific filtering at the source, inside the kernel:
Running system wide: (hope there isn't any embarassing stuff here... ;-) )
# perf trace -e tools/perf/examples/bpf/etcsnoop.c
