Larger errors (when within the documented accuracy goals) indicate testsuite limitations rather than glibc bugs.``` Sourceware Commits 2016-03-24 01:33:55 UTC ```This is an automated email from the git hooks/post-receive script.

Bug 19848 reports cases where powl on x86 / x86_64 has error accumulation, for small integer exponents, larger than permitted by glibc's accuracy goals, at least in some rounding modes. This patch further restricts the exponent range for which the small-integer-exponent logic is used to limit the possible error accumulation. Tested for x86_64 and x86 and ulps updated accordingly.

The GNU C Library is used as *the* C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2008. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.24 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html NEWS for version 2.24 ===================== * The minimum Linux kernel version that this version of the GNU C Library can be used with is 3.2, except on i[4567]86 and x86_64, where Linux kernel version 2.6.32 or later suffices (on architectures that already required kernel versions more recent than 3.2, those requirements remain unchanged). Linux 3.2 or later kernel headers are required on all architectures. * The pap_AN locale has been deleted. This has been deprecated for a long time. It has been replaced by pap_AW & pap_CW, both of which have long been included in previous releases. * The readdir_r and readdir64_r functions have been deprecated. It is recommended to use readdir and readdir64 instead. * The type “union wait” has been removed. It was deprecated in the early 1990s and never part of POSIX. Application code should use the int type instead of “union wait”. * A new NSS action is added to facilitate large distributed system administration. The action, MERGE, allows remote user stores like LDAP to be merged into local user stores like /etc/groups in order to provide easy to use, updated, and managed sets of merged credentials. The new action can be used by configuring it in /etc/nsswitch.conf: group: files [SUCCESS=merge] nis Implemented by Stephen Gallagher (Red Hat). * The deprecated __malloc_initialize_hook variable has been removed from the API. * The long unused localedef --old-style option has been removed. It hasn't done anything in over 16 years. Scripts using this option can safely drop it. * nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added to libm. They are defined by TS 18661 and IEEE754-2008. The nextup functions return the next representable value in the direction of positive infinity and the nextdown functions return the next representable value in the direction of negative infinity. These are currently enabled as GNU extensions. Security related changes: * An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It could result in a stack overflow when getnetbyname was called with an overly long name. (CVE-2016-3075) * Previously, getaddrinfo copied large amounts of address data to the stack, even after the fix for CVE-2013-4458 has been applied, potentially resulting in a stack overflow. getaddrinfo now uses a heap allocation instead. Reported by Michael Petlan. (CVE-2016-3706) * The glob function suffered from a stack-based buffer overflow when it was called with the GLOB_ALTDIRFUNC flag and encountered a long file name. Reported by Alexander Cherepanov. (CVE-2016-1234) * The Sun RPC UDP client could exhaust all available stack space when flooded with crafted ICMP and UDP messages. Reported by Aldy Hernandez' alloca plugin for GCC. (CVE-2016-4429) * The IPv6 name server management code in libresolv could result in a memory leak for each thread which is created, performs a failing naming lookup, and exits. Over time, this could result in a denial of service due to memory exhaustion. Reported by Matthias Schiffer.
