CONFIG_KASAN_GENERIC: Generic mode

General informations

The Linux kernel configuration item CONFIG_KASAN_GENERIC:

Help text

Enables generic KASAN mode. Supported in both GCC and Clang. With GCC it requires version 4.9.2 or later for basic support and version 5.0 or later for detection of out-of-bounds accesses for stack and global variables and for inline instrumentation mode (KASAN_INLINE). With Clang it requires version 3.7.0 or later and it doesn't support detection of out-of-bounds accesses for global variables yet. This mode consumes about 1/8th of available memory at kernel start and introduces an overhead of ~x1.5 for the rest of the allocations. The performance slowdown is ~x3. For better error detection enable STACKTRACE. Currently KASAN_GENERIC doesn't work with DEBUG_SLAB (the resulting kernel does not boot).
