this code attempts to use the value of errno from failure of socket or connect to infer availability of the requested address family (v4 or v6). however, in the case where connect failed, there is an intervening call to close between connect and the use of errno. close is not required to preserve errno on success, and in fact the __aio_close code, which is called whenever aio is linked and thus always called in dynamic-linked programs, unconditionally clobbers errno. as a result, getaddrinfo fails with EAI_SYSTEM and errno=ENOENT rather than correctly determining that the address family was unavailable. this fix is based on report/patch by Jussi Nieminen, but simplified slightly to avoid breaking the case where socket, not connect, failed. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
