This is a security-focused general purpose memory allocator providing the
malloc API along with various extensions. It provides substantial hardening
against heap corruption vulnerabilities. The security-focused design also leads
to much less metadata overhead and memory waste from fragmentation than a more
traditional allocator design. It aims to provide decent overall performance
with a focus on long-term performance and memory usage rather than allocator
allocator micro-benchmarks. It has relatively fine-grained locking and will
offer good scalability once arenas are implemented.
This project currently aims to support Android, musl and glibc. It may support
other non-Linux operating systems in the future. For Android and musl, there
will be custom integration and other hardening features. The glibc support will

choices are not configurable and the allocator remains very security-focused
even with all the optional features disabled.
