Description
This testcase is failing starting from Dec 12:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bts-test/2242/
https://jenkins.osmocom.org/jenkins/view/TTCN3-centos/job/TTCN3-centos-bts-test/1314/
"BTS_Tests.ttcn:7242 : Timeout waiting for EST IND"
BTS_Tests.ttcn:9375 BTS_Tests control part
BTS_Tests.ttcn:7267 TC_rll_est_ind testcase
The -latest release is not affected:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-bts-test-latest/
https://jenkins.osmocom.org/jenkins/view/TTCN3-centos/job/TTCN3-centos-bts-test-latest/
The testcase consists of several sub-cases:
7253 testcase TC_rll_est_ind() runs on test_CT {
7254 var RllTestCases tcs := {
7255 /* SAPI0 establishment (contention resolution) */
7256 valueof(t_EITC(0, ts_RslLinkID_DCCH(0), '01020304'O, true)),
7257 /* normal SAPI0 establishment */
7258 valueof(t_EITC(0, ts_RslLinkID_DCCH(0), ''O, true)), // <----- this one is failing
7259 /* SAPI 3 doesn't support contention resolution */
7260 valueof(t_EITC(3, ts_RslLinkID_DCCH(3), '01020304'O, false)),
7261 valueof(t_EITC(3, ts_RslLinkID_SACCH(3), '01020304'O, false)),
7262 /* normal SAPI3 establishment on main DCCH */
7263 valueof(t_EITC(3, ts_RslLinkID_DCCH(3), ''O, true)),
7264 /* normal SAPI3 establishment on SACCH */
7265 valueof(t_EITC(3, ts_RslLinkID_SACCH(3), ''O, true))
7266 };
7267 f_rll_testmatrix(tcs, refers(f_TC_rll_est_ind));
7268 }
I am seeing this error in the logging:
20231214142417312 DRSL ERROR (bts=0,trx=0,ts=1,ss=0) RLL EST IND without contention resolution. (rsl.c:3843)
so assuming it's related to a recently merged patch:
