| Summary | 0002932: mesh api sends uninitialized memory | ||||
| Description | Destroying a tunnel sometimes sends uninitialized memory over a socket. Valgrind detects this (see Additional Information), and attaching via VGDB gives the following: (gdb) print ntohs (*((uint16_t *) buf + 1)) $1 = 274 Looking at gnunet_protocols.h finds the culprit: #define GNUNET_MESSAGE_TYPE_MESH_LOCAL_TUNNEL_DESTROY 274 | ||||
