2015-01-29Initialize nscd stats data [BZ #17892]Siddhesh Poyarekar
The padding bytes in the statsdata struct are not initialized, due to which valgrind throws a warning: ==11384== Memcheck, a memory error detector ==11384== Copyright (C) 2002-2012, and GNU GPL'd, by Julian Seward et al. ==11384== Using Valgrind-3.8.1 and LibVEX; rerun with -h for copyright info ==11384== Command: nscd -d ==11384== Fri 25 Apr 2014 10:34:53 AM CEST - 11384: handle_request: request received (Version = 2) from PID 11396 Fri 25 Apr 2014 10:34:53 AM CEST - 11384: GETSTAT ==11384== Thread 6: ==11384== Syscall param socketcall.sendto(msg) points to uninitialised byte(s) ==11384== at 0x4E4ACDC: send (in /lib64/libpthread-2.12.so) ==11384== by 0x11AF6B: send_stats (in /usr/sbin/nscd) ==11384== by 0x112F75: nscd_run_worker (in /usr/sbin/nscd) ==11384== by 0x4E439D0: start_thread (in /lib64/libpthread-2.12.so) ==11384== by 0x599AB6C: clone (in /lib64/libc-2.12.so) ==11384== Address 0x15708395 is on thread 6's stack Fix the warning by initializing the structure.
