| Summary | 0001586: FS transmits garbage? Syscall param socketcall.sendto(msg) points to uninitialised byte(s) | ||||
| Description | Start hostlist peer (with fs under valgrind with content), start second peer. On P2P core connect I get: Jul 22 13:57:55 transport-8925 WARNING Received `PING' message not destined for me! ==8923== Syscall param socketcall.sendto(msg) points to uninitialised byte(s) ==8923== at 0x5FF15B5: send (in /lib/libc-2.7.so) ==8923== by 0x587FC2C: GNUNET_NETWORK_socket_send (network.c:536) ==8923== by 0x586F2DF: transmit_ready (connection.c:1516) ==8923== by 0x58868F1: run_ready (scheduler.c:604) ==8923== by 0x5886CB5: GNUNET_SCHEDULER_run (scheduler.c:731) ==8923== by 0x588D648: GNUNET_SERVICE_run (service.c:1568) ==8923== by 0x408CC0: main (gnunet-service-fs.c:3808) ==8923== Address 0x75d86c8 is 16 bytes inside a block of size 32,864 alloc'd ==8923== at 0x4C22741: realloc (vg_replace_malloc.c:429) ==8923== by 0x5869839: GNUNET_xrealloc_ (common_allocation.c:131) ==8923== by 0x586F49E: GNUNET_CONNECTION_notify_transmit_ready (connection.c:1595) ==8923== by 0x5869295: GNUNET_CLIENT_notify_transmit_ready (client.c:880) ==8923== by 0x56577B7: trigger_next_request (core_api.c:366) ==8923== by 0x5658BB2: GNUNET_CORE_notify_transmit_ready (core_api.c:946) ==8923== by 0x4038F6: consider_migration (gnunet-service-fs.c:895) ==8923== by 0x4042B4: peer_connect_handler (gnunet-service-fs.c:1215) ==8923== by 0x565793A: main_notify_handler (core_api.c:424) ==8923== by 0x58689E3: receive_task (client.c:543) ==8923== by 0x58868F1: run_ready (scheduler.c:604) ==8923== by 0x5886CB5: GNUNET_SCHEDULER_run (scheduler.c:731) Jul 22 13:57:56 core-8924 ERROR Assertion failed at gnunet-service-core.c:3661. | ||||
| Additional Information | I suspect the cause is this specific call from fs to transmit data in "consider_migration", which somehow (not obvious from code why) fails to initialize some data in the buffer and then the core service complains about it. Still need to look at the exact core assertion failure, maybe that'll help explain things. | ||||

Fixed at least one of those. Was a 'reserved' field not being set to 0. We should add checks on the receiving end for these... |
