Subject: Suppress TSAN errors from libfstrm.so
X-Git-Tag: v9.17.13~29^2
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=c97c6fbfea2a58e95ef58c13b9aec07501496a9e;p=thirdparty%2Fbind9.git

Suppress TSAN errors from libfstrm.so

dnstap_test produces TSAN errors which originate in libfstrm.so. Unless
libfstrm is TSAN clean or a workaround is placed in libfstrm sources,
suppressing TSAN coming from libfstrm is necessary to test DNSTAP under
TSAN.
