- Update to glibc 2.27
* Optimized x86-64 asin, atan2, exp, expf, log, pow, atan, sin, cosf,
sinf, sincosf and tan with FMA
* Optimized x86-64 trunc and truncf for processors with SSE4.1
* Optimized generic expf, exp2f, logf, log2f, powf, sinf, cosf and
sincosf
* In order to support faster and safer process termination the malloc API
family of functions will no longer print a failure address and stack
backtrace after detecting heap corruption
* The abort function terminates the process immediately, without flushing
stdio streams
* On platforms where long double has the IEEE binary128 format (aarch64,
alpha, mips64, riscv, s390 and sparc), the math library now implements
_Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015
These are the same interfaces added in version 2.26 for some platforms where
this format is supported but is not the format of long double
* On platforms with support for _Float64x (aarch64, alpha, i386, ia64,
mips64, powerpc64le, riscv, s390, sparc and x86_64), the math library now
implements interfaces for that type, as defined by ISO/IEC TS
18661-3:2015
* The math library now implements interfaces for the _Float32, _Float64 and
_Float32x types, as defined by ISO/IEC TS 18661-3:2015
* glibc now implements the memfd_create and mlock2 functions on Linux
* Support for memory protection keys was added
* The copy_file_range function was added
* The ldconfig utility now processes `include' directives using the C/POSIX
collation ordering
* Support for two grammatical forms of month names has been added
* Support for the RISC-V ISA running on Linux has been added
* Statically compiled applications attempting to load locales compiled for the

This fixes the problem of getent ahosts localhost returning 127.0.0.1
|
|
_twice_ on systems that have no ipv6 interfaces up (hence are regarded
|
|
as ipv4 only by the lookup code), but still have localhost entries for
|
|
::1 and 127.0.0.1 in /etc/hosts (like most current systems).
|
|
|
|
Remapping ::1 to 127.0.0.1 is bogus when /etc/hosts is correct.
