Daniel Leung 116998c677 tests: kernel: print FAILED when wrong faults caught For some kernel tests, faults and exceptions are expected. They are caught and the test would continue if the reasons for faults are as expected. However, when the unexpected reasons are encountered, the code simply prints a message and calls k_fatal_halt(). When running under twister, these messages are not the expected failed messages so twister will spin till timeout although the execution has already been halted. This adds another printk() before halt to signal twister that the test has failed and bails early. Signed-off-by: Daniel Leung <daniel.leung@intel.com>		2023-02-21 18:06:44 -05:00

Title: Stack Protection Support

Description:

This test verifies that stack canaries operate as expected.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
