Pau Espin Pedrol gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/9993 to look at the new patch set (#2). Change subject: sgsn: Don't attempt to delete GTP pdp ctx if GGSN was restarted ...................................................................... sgsn: Don't attempt to delete GTP pdp ctx if GGSN was restarted Scenario and behaviour before this commit: - Received Echo Reply from GGSN has incremented RestartCounter - func sgsn_ggsn_ctx_drop_all_pdp() is called to dettach all pdp ctx from GGSN and request the MS to deact all related ctx. - DEACT ACCEPT is received from MS, and then it tries to send DEL PDP CTX to GGSN, expecting to receive a Confirmation and only then freeing the pdp ctx. The problem is that since the initial cause of triggering was a GGSN restart, the GGSN doesn't know anything about that pdp ctx anymore, so it's not useful sending it. We can instead dettach the GGSN and libgtp ref at drop_all_pdp() time and then when we receive DEACT ACCEPT from MS we can free the pdp ctx directly.
