FEDORA-2015-4563ef63aa created by codonell 6 years ago for Fedora 23
stable

An invalid optimization in strcoll resulted in incorrect sorting for languages that contained digraphs. The invalid optimization has been removed and the correct sorting restored to languages with digraphs e.g. cs_CZ and da_DK. (#1276711)

A defect in the malloc implementation, present since glibc 2.15 (2012) or glibc 2.10 via --enable-experimental-malloc (2009), could result in the unnecessary serialization of memory allocation requests across threads. The defect is now corrected. Users should see a substantial increase in the concurrent throughput of allocation requests for applications which trigger this bug. Affected applications typically create create and destroy threads frequently (#1279673).

Buggy example:

$ printf '%s\n' aarch64 abc zed | LC_ALL=nb_NO.UTF-8 ltrace -e strcoll sort >/dev/null

Before:

sort->strcoll("aarch64", "abc")                                  = -1

After:

sort->strcoll("aarch64", "abc")                                  = 28
