TPM2 test cases failed to load share libraries in checkbox-snappy + checkbox18 environment

[Robert Liu]

The TPM test cases worked with checkbox-snappy before (couple days ago).
After upgraded to the new checkbox-snappy + checkbox18, the TPM2 test cases failed.
The error showed libtcti-socket.so.0 is not found.

The output log:
tpm2_takeownership: error while loading shared libraries: libtcti-socket.so.0: cannot open shared object file: No such file or directory

[1;33m\[0mtpm2_takeownership -c on line 47 failed: 127
tpm2_listpersistent: error while loading shared libraries: libtcti-socket.so.0: cannot open shared object file: No such file or directory

[1;31mtest_tpm2_takeownership.sh ... FAILED[0m

Weird that all tpm2 libs are not in /lib/x86_64-linux-gnu/:

/snap/checkbox18/current/lib$ ls
./ libsapi.so.0@ libtcti-socket.a python3.6/
../ libsapi.so.0.0.0* libtcti-socket.so@ systemd/
fwts/ libtcti-device.a libtcti-socket.so.0@ udev/
hdparm/ libtcti-device.so@ libtcti-socket.so.0.0.0* x86_64-linux-gnu/
libsapi.a libtcti-device.so.0@ modprobe.d/
libsapi.so@ libtcti-device.so.0.0.0* pkgconfig/

The reason why we start to fail the tests since the move to checkbox18+checkbox-snappy is that we don't include /lib in wrapper_common LD_LIBRARY_PATH additional paths:

https://git.launchpad.net/checkbox-snappy/tree/launchers/wrapper_common#n55

  append_dir LD_LIBRARY_PATH $RUNTIME/lib/$ARCH
  append_dir LD_LIBRARY_PATH $RUNTIME/usr/lib/$ARCH
  append_dir LD_LIBRARY_PATH $RUNTIME/lib/fwts

So that's a fix for checkbox-snappy only (in wrapper common) and probably just for the 18 track though it would be good to port the same fix to series16 even if so far nothing is in /lib:

/snap/checkbox/current/lib$ ls
./ ../ fwts/ hdparm/ modprobe.d/ python3.5/ systemd/ udev/ x86_64-linux-gnu/

@Robert you can try checkbox-snappy from edge to verify the fix works (in revision 1947):

snap install checkbox-snappy --devmode --channel=18/edge

@Sylvain,

Thanks for the prompt reply.

I've tried the revision on the edge channel and the TPM2 test cases work properly now.
