[PATCH 5/5] lkdtm: Add tests for struct list corruption

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.

[PATCH 1/5] list: Split list_add() debug checking into separate function

Right now, __list_add() code is repeated either in list.h or in list_debug.c, but only the debug checks are the different part. This extracts the checking into a separate function and consolidates __list_add(). Additionally this __list_add_debug() will stop list manipulations if a corruption is

[PATCH 4/5] bug: Provide toggle for BUG on data corruption

The kernel checks for several cases of data structure corruption under either normal runtime, or under various CONFIG_DEBUG_* settings. When corruption is detected, some systems may want to BUG() immediately instead of letting the corruption continue. Many of these manipulation primitives can be
