Description

We are seeing rcp utility (Part of intetutils package) not copying sub directory files.

Earlier, rcp directory copy was not working fully. With the fix provided by LIN9-8513, only files in one of the directories was being successfully copied and files from other sub directories are still not copied.

Looks like patch from LIN9-8513 did not fix this issue completely.

Workaround

NA

Steps to Reproduce

WRL9 OVP host project - WRL9 RCPL0023

wrlinux-9/setup.sh --dl-layers --distros wrlinux-ovp --machines intel-x86-64 --kernel ovp --templates feature/kernel-ovp-kvm --layers wr-kernel wr-ovp

. ./environment-setup-x86_64-wrlinuxsdk-linux
. ./oe-init-build-env build

bitbake wrlinux-image-ovp-kvm

Deploy bzImage and rootfs to target and boot it.

-> Configure xinetd to use rcp. Refer - [http://git.wrs.com/cgi-bin/cgit.cgi/projects/wassp-repos/testcases/wrlinux/commit/wr-testing?id=af1ff029a0d20242521f699e5fb3a8b0047b7299]

-> You can observe that directory rccopy/fold1, rccopy/fold2, rccopy/fold3 are copied. But files under fold3 only is copied and files under fold1 & fold2 are not copied. This issue was not observed with box running inetutils 1.9.1 package in customer tests.
