Rich Felker 39838619bb syslog: use C locale for timestamp generation 
depending on contents of the LC_TIME locale, log messages could be
malformatted (especially if the ABMON strings contain non-alphabetic
characters) or the subsequent code could invoke undefined behavior,
via passing a timebuf[] with unspecified contents to snprintf, if
the translated ABMON string did not fit in the 16-byte timebuf.

this does not appear to be a security-relevant bug, as locale loading
functionality is intentionally not available to set*id programs -- the
MUSL_LOCPATH environment variable is ignored when libc.secure is true,
and custom locales are not loadable without it.

    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
the project website:
