Subject: [PATCH] libselinux/audit2why.so: Filter out non-python related symbols
Date: Tue, 15 Jan 2019 14:36:29 +0100	[thread overview]
Message-ID: <20190115133629.21263-1-plautrba@redhat.com> (raw)
In-Reply-To: <353f9889-d43c-9a14-4605-5ba1eac22284@tycho.nsa.gov>

audit2why.so used to export libsepol.a symbols. We only need Python related
symbols:

- initaudit2why for python 2
- PyInit_audit2why for python3
