    musl is a

    libc implementation.[4]

    Overview

    musl was designed from scratch to allow efficient

    race conditions, internal failures on resource exhaustion, and various other bad worst-case behaviors present in existing implementations.[4] The dynamic runtime is a single file with stable ABI
    allowing race-free updates and the static linking support allows an application to be deployed as a single portable binary without significant size overhead.

    It claims compatibility with the

    BSD, and glibc functions.[5] There is partial ABI compatibility with the part of glibc required by Linux Standard Base.[6]

    Version 1.2.0 has support for (no longer current)

    dlmalloc-like allocator that suffered from fundamental design problems."[2]

    Use

    Some

    seL4 microkernel[16] ships with musl. For binaries that have been linked against glibc, gcompat[17]
    can be used to execute them on musl-based distros.
