Description

Customer found that there is memory leak in wrlinux6 sshd and ntpd.
Customer use Wrlinux6 OVP RCPL 20 with their project.
They run valgrind on target to check moemory leak and see the following result:

I can see the same result in my side.
Though this issue is seen on a wrlinux6 OVP target, but I think it's common wrlinux6 packages, so I file this defect to LIN6 project.
Please check if the memory leak reported by valgrind need to be fixed in wrlinux6.

Steps to Reproduce

1. configure project with following options:
/opt/WRLX6/wrlinux-6/wrlinux/configure --enable-board=intel-x86-64 --enable-kernel=preempt-rt --enable-rootfs=ovp-kvm --enable-addons=wr-ovp --enable-sdkimage-staticlibs=yes --with-template=feature/kvm,feature/benchmark,feature/debug,feature/gdb,feature/kdump,feature/kexec,feature/kernel-debug,feature/kernel-tune,feature/build_libc,feature/dpdk-vswitch --enable-parallel-pkgbuilds=8 --enable-jobs=8 --enable-checkout-all-layers=yes --with-package=wrs-kvm-helper,qemu,libvirt,libvirt-libvirtd,libvirt-virsh,kernel-module-kvm,kernel-module-kvm-intel,kernel-module-kvm-amd,bridge-utils,inetutils,inetutils-rshd,inetutils-telnetd,inetutils-ftpd,ltp --enable-rm-oldimgs=yes --enable-internet-download=yes --enable-reconfig --with-rcpl-version=0020

2. make start-target
    
3. Run valgrind to check the memory leak with sshd and ntpd:
valgrind --tool=memcheck --leak-check=full /usr/sbin/ntpd
valgrind --tool=memcheck --leak-check=full /usr/sbin/sshd
