New patches +addressing important issues have been submitted but these have not been +reviewed nor have they been committed to the master branch. Also, +backporting even those patches which have been committed to master is +now impractical as too many intermediate layers of patches conflict. +For all intents and purposes, upstream uClibc is dead. + +Fortunately, a fork called uClibc-ng [2] was begun by Waldemar Brodkorb +in February 2015 and is actively being maintained. Accordingly, +Gentoo's Hardened uClibc project will be migrating to uClibc-ng as its +libc provider. Currently stage3 tarballs based on sys-libs/uclibc-ng +are available for all supported arches at [3] and these will become the +default after October 5, 2016. Older stage3s based on sys-libs/uclibc +will be removed. + +Unfortunately, migrating a production system from uclibc to uclibc-ng +is not straightforward owing to the central role played by libc. A +migration guide is provided at [4]. This has been tested on live +systems with success, but the user is cautioned to plan a backup and +recovery plan should something go wrong. + +Refs. +[1] https://git.uclibc.org/uClibc/log/ +[2] http://uclibc-ng.org/ +[3] http://distfiles.gentoo.org/experimental/ +[4] https://wiki.gentoo.org/wiki/Project:Hardened_uClibc#Migration_to_uClibc-ng |
