Harald Welte gerrit-no-reply at lists.osmocom.orgHarald Welte has uploaded this change for review. ( https://gerrit.osmocom.org/13564 Change subject: ggsn: Add TC_pdp4_act_deact_ipcp_pap_broken() ...................................................................... ggsn: Add TC_pdp4_act_deact_ipcp_pap_broken() This test case reproduces a real-world PCO capture including a broken PAP AuthenticationReq. It triggers some weird behavior in OsmoGGSN 1.3.0 where it would send duplicate IPCP repsonses and no PAP response.
