musl - an implementation of the standard library for Linux-based systems
d8f35e29d0
the aio operations that lead to calling __aio_get_queue with the possibility to expand the fd map are not AS-safe, but if they are interrupted by a signal handler, the signal handler may call close, which is required to be AS-safe. due to __aio_get_queue taking the write lock without blocking signals, such a call to close from a signal handler could deadlock. change __aio_get_queue to block signals if it needs to obtain a write lock, and restore when finished. |

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
