This causes the crash. * * PROBLEM SUMMARY: * Crash in ncs_unreserve_tg_number when doing define_ls * (inadvertently from xsnaadmin) on an on-demand non-SATF link * (SDLC/QLLC/Channel) which has been disabled and has received * a failed incoming connection. There is a less fatal symptom * that may be seen that the define_ls fails with an error about * duplicate TG numbers. * * PROBLEM CONCLUSION: * On-demand links have pre-defined TG numbers. non_SATF incoming * links need to use temporary links during the start up process. * There is a bug where we fail to switch the TG details between * the temporary link and the real link when the first XID3 is * received. The code has been change to correct this. * * Also included in this updated module are fixes for the following APARs: * iy46595 sna_v5router (requires sna_mux to be complete) * iy47993 sna_v5router * iy49236 sna_v5router (requires liblua.o to be complete) * iy50234 sna_v5router * iy51222 sna_v5router * iy51514 sna_v5router * *+----------------------------------------------------------------------------+ * * INSTALLATION INSTRUCTIONS: * __________________________ * * iy51514.tar.Z ("this fix" in the steps below) is a compressed tar archive * file containing the updated modules and this readme. * * * To install this fix: * _____________________________ * * ** Downloading the file: * * 1) Be SURE to download this fix in BINARY format. * * 2) Check the output of sum against the updated module after * uncompressing and untarring this fix.
