| Summary | 0001685: uninitialized message fields somewhere in chat code | ||||
| Description | When running $ valgrind --trace-children=yes .libs/lt-test_chat_private_p2p against SVN 15431, I get a warning about uninitialized bytes being passed to 'send'. This typically happens if some members of some message struct (often unused ones) are not initialized by the code prior to transmission. | ||||
| Additional Information | ==8882== Syscall param socketcall.send(msg) points to uninitialised byte(s) ==8882== at 0x4169F61: send (socket.S:64) ==8882== by 0x4046051: transmit_ready (connection.c:1561) ==8882== by 0x405E50F: run_ready (scheduler.c:643) ==8882== by 0x405EAF0: GNUNET_SCHEDULER_run (scheduler.c:790) ==8882== by 0x405AF18: GNUNET_PROGRAM_run (program.c:227) ==8882== by 0x8049ED3: main (test_chat_private.c:675) ==8882== Address 0x4588de4 is 12 bytes inside a block of size 342 alloc'd ==8882== at 0x402695A: realloc (vg_replace_malloc.c:525) ==8882== by 0x403FA8D: GNUNET_xrealloc_ (common_allocation.c:167) ==8882== by 0x4045EFD: transmit_ready (connection.c:1546) ==8882== by 0x405E50F: run_ready (scheduler.c:643) ==8882== by 0x405EAF0: GNUNET_SCHEDULER_run (scheduler.c:790) ==8882== by 0x405AF18: GNUNET_PROGRAM_run (program.c:227) ==8882== by 0x8049ED3: main (test_chat_private.c:675) | ||||
