linux-stable.git/tools/testing/selftests/livepatch/functions.sh, branch linux-5.2.y Linux kernel stable tree livepatch/selftests: use "$@" to preserve argument list 2019-02-12T09:58:47+00:00 Joe Lawrence joe.lawrence@redhat.com 2019-02-08T20:57:37+00:00 fbb76d579dff4a2e332566dcd1d5979ac92bc34b The livepatch selftest functions.sh library uses "$*" and an intermediate variable to extract and then pass arguments from function to function call. The effect of this combination is that the argument list is flattened into a single argument. Sometimes this is benign, but in cases like __load_mod(), the modprobe invocation will interpret all the module parameters as a single parameter. Drop the intermediate variable and use the "$@" special parameter as described in the bash manual.

Add a few livepatch modules and simple target modules that the included
regression suite can run tests against:

  - basic livepatching (multiple patches, atomic replace)
  - pre/post (un)patch callbacks
  - shadow variable API
