As per the recent discussion, this patch implements a requirement for Linux 3.2 or later for x86 and x86_64. This is only the initial change to increase the configured minimum; it's expected that followup patches would deal with associated removal of conditionals that are no longer needed. If we remove the start-up test on the kernel version, of course the NEWS and README text should then be revised (to reflect that this version is just one such that glibc does not intend to include compatibility code for any older kernel version, rather than older kernels necessarily failing to work or glibc necessarily having compatibility code for newer interfaces). The followups would be able to assume presence of getcpu (x86_64), recvmmsg (not always through its own syscall, sometimes only through socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags from statfs, prlimit64. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/i386/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/i386/configure: Regenerated. * sysdeps/unix/sysv/linux/x86_64/64/configure.ac (arch_minimum_kernel): Remove. * sysdeps/unix/sysv/linux/x86_64/64/configure: Regenerated. * README: Update statement about Linux kernel requirements.

This directory contains the sources of the GNU C Library.
|
|
See the file "version.h" for what release version you have.
|
|
|
|
The GNU C Library is the standard system C library for all GNU systems,
|
|
and is an important part of what makes up a GNU system. It provides the
|
|
system API for all programs written in C and C-compatible languages such
|
|
as C++ and Objective C; the runtime facilities of other programming
|
|
languages use the C library to access the underlying operating system.
|
|
|
|
In GNU/Linux systems, the C library works with the Linux kernel to
|
|
implement the operating system behavior seen by user applications.
|
|
In GNU/Hurd systems, it works with a microkernel and Hurd servers.
|
|
|
|
The GNU C Library implements much of the POSIX.1 functionality in the
|
|
GNU/Hurd system, using configurations i[4567]86-*-gnu. The current
|
|
GNU/Hurd support requires out-of-tree patches that will eventually be
|
|
incorporated into an official GNU C Library release.
|
|
|
|
When working with Linux kernels, this version of the GNU C Library
|
|
requires Linux kernel version 3.2 or later.
|
|
|
|
Also note that the shared version of the libgcc_s library must be
|
|
installed for the pthread library to work correctly.
|
|
|
|
The GNU C Library supports these configurations for using Linux kernels:

See the file INSTALL to find out how to configure, build, and install
|
|
the GNU C Library. You might also consider reading the WWW pages for

the C library at http://www.gnu.org/software/libc/.
|
|
|
|
The GNU C Library is (almost) completely documented by the Texinfo manual
|
|
found in the `manual/' subdirectory. The manual is still being updated
|
|
and contains some known errors and omissions; we regret that we do not
|
|
have the resources to work on the manual as much as we would like. For
|
|
corrections to the manual, please file a bug in the `manual' component,
|
|
following the bug-reporting instructions below. Please be sure to check
|
|
the manual in the current development sources to see if your problem has
|
|
already been corrected.
|
|
|
|
Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
|
|
information. We are now using the Bugzilla system to track all bug reports.
|
|
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software. See the file COPYING.LIB for copying
|
|
conditions, and LICENSES for notices about a few contributions that require
|

these additional notices to be distributed. License copyright years may be
|

listed using range notation, e.g., 1996-2015, indicating that every year in
