lkdtm: Convert to refcount_t testing

2017-02-10T08:04:20+00:00

Since we'll be using refcount_t instead of atomic_t for refcounting,
change the LKDTM tests to reflect the new interface and test conditions.

lkdtm: Add tests for struct list corruption

2016-10-31T20:01:58+00:00

When building under CONFIG_DEBUG_LIST, list addition and removal will be
sanity-checked. This validates that the check is working as expected by
setting up classic corruption attacks against list manipulations, available
with the new lkdtm tests CORRUPT_LIST_ADD and CORRUPT_LIST_DEL.

lkdtm: silence warnings about function declarations

2016-07-15T23:14:45+00:00

When building under W=1, the lack of lkdtm.h in lkdtm_usercopy.c and
lkdtm_rodata.c was discovered. This fixes the issue and consolidates
the common header and the pr_fmt macro for simplicity and regularity
across each test source file.

lkdtm: split remaining logic bug tests to separate file

2016-07-07T18:09:22+00:00

This splits all the remaining tests from lkdtm_core.c into the new
lkdtm_bugs.c file to help separate things better for readability.

This splits the *_AFTER_FREE and related tests into the new lkdtm_heap.c
file to help separate things better for readability.

2016-07-07T18:09:21+00:00

This splits the EXEC_*, WRITE_* and related tests into the new lkdtm_perms.c
file to help separate things better for readability.

lkdtm: split usercopy tests to separate file

2016-07-07T18:09:20+00:00

lkdtm: add function for testing .rodata section

2016-06-10T22:57:50+00:00

This adds a function that lives in the .rodata section. The section
flags are corrected using objcopy since there is no way with gcc to
declare section flags in an architecture-agnostic way.
