From 97602d973457a5248ada6ca9e5c29c1a5811240d Mon Sep 17 00:00:00 2001 From: Holger Hans Peter Freyther Date: Sun, 11 Nov 2012 14:21:26 +0100 Subject: fr: Begin with a GRE/FrameRelay test due the recent regression The framerelay code is seldomly used and the socket clean ups introduced a regression. Create a testcase that will work as a user not having the right capabilities to create raw sockets. We have to make sure that this test is working even when not ran as root. The easiest way to do this is to provide our own socket implementation. This is done with dlopen/dlsym to convert the raw socket request to an UDP one. --- .gitignore | 1 + tests/Makefile.am | 9 +++++-- tests/fr/fr_test.c | 76 ++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/fr/fr_test.err | 0 tests/fr/fr_test.ok | 1 + tests/testsuite.at | 8 ++++++ 6 files changed, 93 insertions(+), 2 deletions(-) create mode 100644 tests/fr/fr_test.c create mode 100644 tests/fr/fr_test.err create mode 100644 tests/fr/fr_test.ok diff --git a/.gitignore b/.gitignore index ac19b238..24ca6778 100644 --- a/.gitignore +++ b/.gitignore @@ -68,6 +68,7 @@ tests/gsm0808/gsm0808_test tests/gb/bssgp_fc_test tests/gsm0408/gsm0408_test tests/logging/logging_test +tests/fr/fr_test utils/osmo-arfcn utils/osmo-auc-gen diff --git a/tests/Makefile.am b/tests/Makefile.am index b60f6758..be0b5f4c 100644 --- a/tests/Makefile.am +++ b/tests/Makefile.am @@ -4,7 +4,7 @@ check_PROGRAMS = timer/timer_test sms/sms_test ussd/ussd_test \ smscb/smscb_test bits/bitrev_test a5/a5_test \ conv/conv_test auth/milenage_test lapd/lapd_test \ gsm0808/gsm0808_test gsm0408/gsm0408_test \ - gb/bssgp_fc_test logging/logging_test + gb/bssgp_fc_test logging/logging_test fr/fr_test if ENABLE_MSGFILE check_PROGRAMS += msgfile/msgfile_test endif @@ -51,6 +51,10 @@ gb_bssgp_fc_test_LDADD = $(top_builddir)/src/libosmocore.la $(top_builddir)/src/ logging_logging_test_SOURCES = logging/logging_test.c logging_logging_test_LDADD = $(top_builddir)/src/libosmocore.la +fr_fr_test_SOURCES = fr/fr_test.c +fr_fr_test_LDADD = $(top_builddir)/src/libosmocore.la $(top_builddir)/src/gb/libosmogb.la + + # The `:;' works around a Bash 3.2 bug when the output is not writeable. $(srcdir)/package.m4: $(top_srcdir)/configure.ac :;{ \ @@ -77,7 +81,8 @@ EXTRA_DIST = testsuite.at $(srcdir)/package.m4 $(TESTSUITE) \ gsm0808/gsm0808_test.ok gb/bssgp_fc_tests.err \ gb/bssgp_fc_tests.ok gb/bssgp_fc_tests.sh \ msgfile/msgfile_test.ok msgfile/msgconfig.cfg \ - logging/logging_test.ok logging/logging_test.err + logging/logging_test.ok logging/logging_test.err \ + fr/fr_test.ok DISTCLEANFILES = atconfig diff --git a/tests/fr/fr_test.c b/tests/fr/fr_test.c new file mode 100644 index 00000000..c09ce7b4 --- /dev/null +++ b/tests/fr/fr_test.c @@ -0,0 +1,76 @@ +/* + * (C) 2012 by Holger Hans Peter Freyther + * All Rights Reserved + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU Affero General Public License as published by + * the Free Software Foundation; either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
