Description

Found in relation to WIND00401487

When I did with defect WIND00401487:
"[Feature Testing][networking]: the case gdb.sh in CUT will failed if your terminal window is not big enough",
gdb will display:

warning: Could not load shared library symbols for linux-vdso32.so.1.
Do you need "set solib-search-path" or "set sysroot"?

This is a minor known bug. The patch gdb-glibc-vdso-workaround.patch can fix it.
But I can not make sure whether we should fix it or not. So I write this mail.



gdb-glibc-vdso-workaround.patch

Steps to Reproduce

Following steps are taken from WIND00401487:

Steps To Reproduce: 1 configure a project
/buildarea/product/LX22_12SP_501/wrlinux-5/wrlinux/configure --enable-board=intel-xeon-core --enable-kernel=cgl --enable-rootfs=glibc_cgl --enable-parallel-pkgbuilds=16 --enable-jobs=8 --with-layer=wr-features,examples/hello-world,/wr-testing/cgl,/wr-testing/ltp,/wr-testing/networking --with-template=feature/lsbtesting,feature/hello-world,feature/cut --with-sstate-dir=/sstate-intel-xeon-core
2. make fs
3. start the target with the kernel and rootfs
4. make your terminal window small enough, such as 1/3 full screen.
5. on target:
	cd /opt/cut
	./cgl_test.sh -e gdb.sh
