Component INIT_ON_ALLOC_DEFAULT_ON

Component Type: kbuild config

Description: Enable heap memory zeroing on allocation by default

More info: This has the effect of setting "init_on_alloc=1" on the kernel command line. This can be disabled with "init_on_alloc=0". When "init_on_alloc" is enabled, all page allocator and slab allocator memory will be zeroed when allocated, eliminating many kinds of "uninitialized heap memory" flaws, especially heap content exposures. The performance impact varies by workload, but most cases see <1% impact. Some synthetic workloads have measured as high as 7%.
