Di Nitto <fdinitto(a)redhat.com> Date: 2019-03-24 (Sun, 24 Mar 2019) Changed paths: M libknet/transport_sctp.c M libknet/transport_udp.c Log Message: ----------- [transports] fix usage after free of transport info memory spotted while implementing functional testing for rekey. when configuring multiple hosts (3+) with 1 link sharing the same listener, but NOT enabling the link, if the user attempts to shutdown knet_h, the first call to knet_link_clear_config will not recognize that the listener is still in use by another link and will release all resources. At the time of invoking clear_config on the second link, transport_clear_config will access already freed memory, or alternatively, a call to link_enable would cause a crash because the listener does no longer exist.
