+Quote from bug 1443 which explains what the patch does : 
+
+  We build some random program and link it with -lust.  When we run it,
+  it dies with a SIGSEGV before reaching main().
+  
+  Libust.so depends on liburcu-bp.so from the usermode-rcu package.
+  Although libust.so is not prelinked, liburcu-bp.so IS prelinked; this
+  is critical.
+  
+  Libust.so uses a TLS / __thread variable that is defined in liburcu-
+  bp.so.  There are special ARM-specific relocation types that allow two
+  shared libraries to share thread-specific data.  This is critical too.
+  
+  One more critical issue: although liburcu-bp.so is prelinked, we can't
+  load it at its prelinked address, because we also link against
+  librt.so, and librt.so uses that address.
+  
+  The dynamic linker is forced to relink liburcu-bp.so at a different
+  address.  In the course of relinking, it processes the special ARM
+  relocation record mentioned above.  The prelinker has already filled
+  in the information, which is a short offset into a table of thread-
+  specific data that is allocated per-thread for each library that uses
+  TLS.  Because the normal behavior of a relocation is to add the symbol
+  value to an addend stored at the address being relocated, we end up
+  adding the short offset to itself, doubling it.
+  
+  Now we have an awkward situation.  The libust.so library doesn't know
+  about the addend, so its TLS data for this element is correct.  The
+  liburcu-bp.so library has a different offset for the element.  When we
+  go to initialize the element for the first time in liburcu-bp.so, we
+  write the address of the result at the doubled (broken) offset.
+  Later, when we refer to the address from libust.so, we check the value
+  at the correct offset, but it's NULL, so we eat hot SIGSEGV.

+libm-err-tab.pl will parse all the files named "libm-test-ulps"
+in the given dir recursively. To avoid parsing the one in
+${S}/.pc/ (it does exist after eglibc adds aarch64 support,
+${S}/.pc/aarch64-0001-glibc-fsf-v1-eaf6f205.patch/ports/sysdeps/
+aarch64/libm-test-ulps), run libm-err-tab.pl with specific dirs
+in ${S}.

+Subject: [PATCH] CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
+
+The function wordexp() fails to properly handle the WRDE_NOCMD
+flag when processing arithmetic inputs in the form of "$((... ``))"
+where "..." can be anything valid. The backticks in the arithmetic
+epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+command substitution. This allows an attacker to attempt to pass
+dangerous commands via constructs of the above form, and bypass
+the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+in exec_comm(), the only place that can execute a shell. All other
+checks for WRDE_NOCMD are superfluous and removed.
+
+We expand the testsuite and add 3 new regression tests of roughly
+the same form but with a couple of nested levels.
+
+On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+testing. If any forks are detected during the execution of a wordexp()
+call with WRDE_NOCMD, the test is marked as failed. This is slightly
+heuristic since vfork might be used in the future, but it provides a
+higher level of assurance that no shells were executed as part of
+command substitution with WRDE_NOCMD in effect. In addition it doesn't
+require libpthread or libdl, instead we use the public implementation
+namespace function __register_atfork (already part of the public ABI
+for libpthread).
+
+Tested on x86_64 with no regressions.

++/* When OPTION_EGLIBC_NSSWITCH is disabled (see option-groups.def),
++   EGLIBC does not use the 'dlopen' and 'dlsym' functions to look for
++   database query functions in the individual name service libraries.
++   Instead, it uses a set of functions chosen at compile time, as
++   directed by the OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS file.  This
++   file is a sample of what you might use there.
++
++   This file is C source code; it should only contain invocations of
++   the following macros:
++
++   - DEFINE_ENT (DATABASE, SERVICE, X)
++
++     Declare the 'setXent', 'getXent_r', and 'endXent' functions that
++     query DATABASE using the service library 'libnss_SERVICE.so.2'.
++     DATABASE should be the full name of the database as it appears in
++     'nsswitch.conf', like 'passwd' or 'aliases'.
++
++     (The non-reentrant 'getXent' functions are implemented in terms
++     of the reentrant 'getXent_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   - DEFINE_GETBY (DATABASE, SERVICE, X, KEY)
++
++     Declare the 'getXbyKEY_r' functions that query DATABASE using
++     SERVICE.  DATABASE and SERVICE are as described above.
++
++     (The non-reentrant 'getXbyKEY' functions are implemented in terms
++     of the reentrant 'getXbyKEY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++     Use the special key 'name3' for the service library function that
++     implements the 'getaddrinfo' function.
++
++   - DEFINE_GET (DATABASE, SERVICE, QUERY)
++
++     Declare the 'getQUERY_r' functions that query DATABASE using
++     SERVICE.  This is used for functions like 'getpwnam'.
++
++     (The non-reentrant 'getQUERY' functions are implemented in terms
++     of the reentrant 'getQUERY_r' functions, so there is no need to
++     refer to them explicitly here.)
++
++   This sample file only includes functions that consult the files in
++   '/etc', and the Domain Name System (DNS).  */

++
++Introduction
++
++Most GNU tools have a simple build procedure: you run their
++'configure' script, and then you run 'make'.  Unfortunately, the
++process of cross-compiling the GNU C library is quite a bit more
++involved:
++
++1) Build a cross-compiler, with certain facilities disabled.
++
++2) Configure the C library using the compiler you built in step 1).
++   Build a few of the C run-time object files, but not the rest of the
++   library.  Install the library's header files and the run-time
++   object files, and create a dummy libc.so.
++
++3) Build a second cross-compiler, using the header files and object
++   files you installed in step 2.
++
++4) Configure, build, and install a fresh C library, using the compiler
++   built in step 3.
++
++5) Build a third cross-compiler, based on the C library built in step 4.
++
++The reason for this complexity is that, although GCC and the GNU C
++library are distributed separately, they are not actually independent
++of each other: GCC requires the C library's headers and some object
++files to compile its own libraries, while the C library depends on
++GCC's libraries.  EGLIBC includes features and bug fixes to the stock
++GNU C library that simplify this process, but the fundamental
++interdependency stands.
++
++In this document, we explain how to cross-compile an EGLIBC/GCC pair
++from source.  Our intended audience is developers who are already
++familiar with the GNU toolchain and comfortable working with
++cross-development tools.  While we do present a worked example to
++accompany the explanation, for clarity's sake we do not cover many of
++the options available to cross-toolchain users.
++
++
++Preparation
++
++EGLIBC requires recent versions of the GNU binutils, GCC, and the
++Linux kernel.  The web page <http://www.eglibc.org/prerequisites>
++documents the current requirements, and lists patches needed for
++certain target architectures.  As of this writing, these build
++instructions have been tested with binutils 2.22.51, GCC 4.6.2,
++and Linux 3.1.
++
++First, let's set some variables, to simplify later commands.  We'll
++build EGLIBC and GCC for an ARM target, known to the Linux kernel
++as 'arm', and we'll do the build on an Intel x86_64 Linux box:
++
++    $ build=x86_64-pc-linux-gnu
++    $ host=$build
++    $ target=arm-none-linux-gnueabi
++    $ linux_arch=arm
++
++We're using the aforementioned versions of Binutils, GCC, and Linux:
++
++    $ binutilsv=binutils-2.22.51
++    $ gccv=gcc-4.6.2
++    $ linuxv=linux-3.1
++
++We're carrying out the entire process under '~/cross-build', which
++contains unpacked source trees for binutils, gcc, and linux kernel,
++along with EGLIBC svn trunk (which can be checked-out with
++'svn co http://www.eglibc.org/svn/trunk eglibc'):
++
++    $ top=$HOME/cross-build/$target
++    $ src=$HOME/cross-build/src
++    $ ls $src
++    binutils-2.22.51  eglibc  gcc-4.6.2  linux-3.1
++
++We're going to place our build directories in a subdirectory 'obj',
++we'll install the cross-development toolchain in 'tools', and we'll
++place our sysroot (containing files to be installed on the target
++system) in 'sysroot':
++
++    $ obj=$top/obj
++    $ tools=$top/tools
++    $ sysroot=$top/sysroot
++
++
++Binutils
++
++Configuring and building binutils for the target is straightforward:
++
++    $ mkdir -p $obj/binutils
++    $ cd $obj/binutils
++    $ $src/$binutilsv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot
++    $ make
++    $ make install
++
++
++The First GCC
++
++For our work, we need a cross-compiler targeting an ARM Linux
++system.  However, that configuration includes the shared library
++'libgcc_s.so', which is compiled against the EGLIBC headers (which we
++haven't installed yet) and linked against 'libc.so' (which we haven't
++built yet).
++
++Fortunately, there are configuration options for GCC which tell it not
++to build 'libgcc_s.so'.  The '--without-headers' option is supposed to
++take care of this, but its implementation is incomplete, so you must
++also configure with the '--with-newlib' option.  While '--with-newlib'
++appears to mean "Use the Newlib C library", its effect is to tell the
++GCC build machinery, "Don't assume there is a C library available."
++
++We also need to disable some of the libraries that would normally be
++built along with GCC, and specify that only the compiler for the C
++language is needed.
++
++So, we create a build directory, configure, make, and install.
++
++    $ mkdir -p $obj/gcc1
++    $ cd $obj/gcc1
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --without-headers --with-newlib \
++    >     --disable-shared --disable-threads --disable-libssp \
++    >     --disable-libgomp --disable-libmudflap --disable-libquadmath \
++    >     --disable-decimal-float --disable-libffi \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++Linux Kernel Headers
++
++To configure EGLIBC, we also need Linux kernel headers in place.
++Fortunately, the Linux makefiles have a target that installs them for
++us.  Since the process does modify the source tree a bit, we make a
++copy first:
++
++    $ cp -r $src/$linuxv $obj/linux
++    $ cd $obj/linux
++
++Now we're ready to install the headers into the sysroot:
++
++    $ PATH=$tools/bin:$PATH \
++    > make headers_install \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    >      INSTALL_HDR_PATH=$sysroot/usr
++
++
++EGLIBC Headers and Preliminary Objects
++
++Using the cross-compiler we've just built, we can now configure EGLIBC
++well enough to install the headers and build the object files that the
++full cross-compiler will need:
++
++    $ mkdir -p $obj/eglibc-headers
++    $ cd $obj/eglibc-headers
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/eglibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++The option '--prefix=/usr' may look strange, but you should never
++configure EGLIBC with a prefix other than '/usr': in various places,
++EGLIBC's build system checks whether the prefix is '/usr', and does
++special handling only if that is the case.  Unless you use this
++prefix, you will get a sysroot that does not use the standard Linux
++directory layouts and cannot be used as a basis for the root
++filesystem on your target system compatibly with normal GLIBC
++installations.
++
++The '--with-headers' option tells EGLIBC where the Linux headers have
++been installed.
++
++The '--enable-add-ons=nptl,libidn,../ports' option tells EGLIBC to look
++for the listed glibc add-ons. Most notably the ports add-on (located
++just above the libc sources in the EGLIBC svn tree) is required to
++support ARM targets.
++
++We can now use the 'install-headers' makefile target to install the
++headers:
++
++    $ make install-headers install_root=$sysroot \
++    >                      install-bootstrap-headers=yes
++
++The 'install_root' variable indicates where the files should actually
++be installed; its value is treated as the parent of the '--prefix'
++directory we passed to the configure script, so the headers will go in
++'$sysroot/usr/include'.  The 'install-bootstrap-headers' variable
++requests special handling for certain tricky header files.
++
++Next, there are a few object files needed to link shared libraries,
++which we build and install by hand:
++
++    $ mkdir -p $sysroot/usr/lib
++    $ make csu/subdir_lib
++    $ cp csu/crt1.o csu/crti.o csu/crtn.o $sysroot/usr/lib
++
++Finally, 'libgcc_s.so' requires a 'libc.so' to link against.  However,
++since we will never actually execute its code, it doesn't matter what
++it contains.  So, treating '/dev/null' as a C source file, we produce
++a dummy 'libc.so' in one step:
++
++    $ $tools/bin/$target-gcc -nostdlib -nostartfiles -shared -x c /dev/null \
++    >                        -o $sysroot/usr/lib/libc.so
++
++
++The Second GCC
++
++With the EGLIBC headers and selected object files installed, we can
++now build a GCC that is capable of compiling EGLIBC.  We configure,
++build, and install the second GCC, again building only the C compiler,
++and avoiding libraries we won't use:
++
++    $ mkdir -p $obj/gcc2
++    $ cd $obj/gcc2
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --disable-libffi --disable-libquadmath \
++    >     --enable-languages=c
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++
++EGLIBC, Complete
++
++With the second compiler built and installed, we're now ready for the
++full EGLIBC build:
++
++    $ mkdir -p $obj/eglibc
++    $ cd $obj/eglibc
++    $ BUILD_CC=gcc \
++    > CC=$tools/bin/$target-gcc \
++    > CXX=$tools/bin/$target-g++ \
++    > AR=$tools/bin/$target-ar \
++    > RANLIB=$tools/bin/$target-ranlib \
++    > $src/eglibc/libc/configure \
++    >     --prefix=/usr \
++    >     --with-headers=$sysroot/usr/include \
++    >     --with-kconfig=$obj/linux/scripts/kconfig \
++    >     --build=$build \
++    >     --host=$target \
++    >     --disable-profile --without-gd --without-cvs \
++    >     --enable-add-ons=nptl,libidn,../ports
++
++Note the additional '--with-kconfig' option. This tells EGLIBC where to
++find the host config tools used by the kernel 'make config' and 'make
++menuconfig'.  These tools can be re-used by EGLIBC for its own 'make
++*config' support, which will create 'option-groups.config' for you.
++But first make sure those tools have been built by running some
++dummy 'make *config' calls in the kernel directory:
++
++    $ cd $obj/linux
++    $ PATH=$tools/bin:$PATH make config \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++    $ PATH=$tools/bin:$PATH make menuconfig \
++    >      ARCH=$linux_arch CROSS_COMPILE=$target- \
++
++Now we can configure and build the full EGLIBC:
++
++    $ cd $obj/eglibc
++    $ PATH=$tools/bin:$PATH make defconfig
++    $ PATH=$tools/bin:$PATH make menuconfig
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install install_root=$sysroot
++
++At this point, we have a complete EGLIBC installation in '$sysroot',
++with header files, library files, and most of the C runtime startup
++files in place.
++
++
++The Third GCC
++
++Finally, we recompile GCC against this full installation, enabling
++whatever languages and libraries we would like to use:
++
++    $ mkdir -p $obj/gcc3
++    $ cd $obj/gcc3
++    $ $src/$gccv/configure \
++    >     --target=$target \
++    >     --prefix=$tools \
++    >     --with-sysroot=$sysroot \
++    >     --enable-__cxa_atexit \
++    >     --disable-libssp --disable-libgomp --disable-libmudflap \
++    >     --enable-languages=c,c++
++    $ PATH=$tools/bin:$PATH make
++    $ PATH=$tools/bin:$PATH make install
++
++The '--enable-__cxa_atexit' option tells GCC what sort of C++
++destructor support to expect from the C library; it's required with
++EGLIBC.
++
++And since GCC's installation process isn't designed to help construct
++sysroot trees, we must manually copy certain libraries into place in
++the sysroot.
++
++    $ cp -d $tools/$target/lib/libgcc_s.so* $sysroot/lib
++    $ cp -d $tools/$target/lib/libstdc++.so* $sysroot/usr/lib
++
++
++Trying Things Out
++
++At this point, '$tools' contains a cross toolchain ready to use
++the EGLIBC installation in '$sysroot':
++
++    $ cat > hello.c <<EOF
++    > #include <stdio.h>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   puts ("Hello, world!");
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-gcc -Wall hello.c -o hello
++    $ cat > c++-hello.cc <<EOF
++    > #include <iostream>
++    > int
++    > main (int argc, char **argv)
++    > {
++    >   std::cout << "Hello, C++ world!" << std::endl;
++    >   return 0;
++    > }
++    > EOF
++    $ $tools/bin/$target-g++ -Wall c++-hello.cc -o c++-hello
++
++
++We can use 'readelf' to verify that these are indeed executables for
++our target, using our dynamic linker:
++
++    $ $tools/bin/$target-readelf -hl hello
++    ELF Header:
++    ...
++      Type:                              EXEC (Executable file)
++      Machine:                           ARM
++
++    ...
++    Program Headers:
++      Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
++      PHDR           0x000034 0x10000034 0x10000034 0x00100 0x00100 R E 0x4
++      INTERP         0x000134 0x00008134 0x00008134 0x00013 0x00013 R   0x1
++          [Requesting program interpreter: /lib/ld-linux.so.3]
++      LOAD           0x000000 0x00008000 0x00008000 0x0042c 0x0042c R E 0x8000
++    ...
++
++Looking at the dynamic section of the installed 'libgcc_s.so', we see
++that the 'NEEDED' entry for the C library does include the '.6'
++suffix, indicating that was linked against our fully build EGLIBC, and
++not our dummy 'libc.so':
++
++    $ $tools/bin/$target-readelf -d $sysroot/lib/libgcc_s.so.1
++    Dynamic section at offset 0x1083c contains 24 entries:
++      Tag        Type                         Name/Value
++     0x00000001 (NEEDED)                     Shared library: [libc.so.6]

++    ...
++
++
++And on the target machine, we can run our programs:
++
++    $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \
++    > ./hello
++    Hello, world!
++    $ $sysroot/lib/ld.so.1 --library-path $sysroot/lib:$sysroot/usr/lib \

++
++Introduction
++
++Developers writing software for embedded systems often use a desktop
++or other similarly capable computer for development, but need to run
++tests on the embedded system, or perhaps on a simulator.  When
++configured for cross-compilation, the stock GNU C library simply
++disables running tests altogether: the command 'make tests' builds
++test programs, but does not run them.  EGLIBC, however, provides
++facilities for compiling tests and generating data files on the build
++system, but running the test programs themselves on a remote system or
++simulator.
++
++
++Test environment requirements
++
++The test environment must meet certain conditions for EGLIBC's
++cross-testing facilities to work:
++
++- Shared filesystems.  The 'build' system, on which you configure and
++  compile EGLIBC, and the 'host' system, on which you intend to run
++  EGLIBC, must share a filesystem containing the EGLIBC build and
++  source trees.  Files must appear at the same paths on both systems.
++
++- Remote-shell like invocation.  There must be a way to run a program
++  on the host system from the build system, passing it properly quoted
++  command-line arguments, setting environment variables, and
++  inheriting the caller's standard input and output.
++
++
++Usage
++
++To use EGLIBC's cross-testing support, provide values for the
++following Make variables when you invoke 'make':
++
++- cross-test-wrapper
++
++  This should be the name of the cross-testing wrapper command, along
++  with any arguments.
++
++- cross-localedef
++
++  This should be the name of a cross-capable localedef program, like
++  that included in the EGLIBC 'localedef' module, along with any
++  arguments needed.
++
++These are each explained in detail below.
++
++
++The Cross-Testing Wrapper
++
++To run test programs reliably, the stock GNU C library takes care to
++ensure that test programs use the newly compiled dynamic linker and
++shared libraries, and never the host system's installed libraries.  To
++accomplish this, it runs the tests by explicitly invoking the dynamic
++linker from the build tree, passing it a list of build tree
++directories to search for shared libraries, followed by the name of
++the executable to run and its arguments.
++
++For example, where one might normally run a test program like this:
++
++    $ ./tst-foo arg1 arg2
++
++the GNU C library might run that program like this:
++
++    $ $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++(where $objdir is the path to the top of the build tree, and the
++trailing backslash indicates a continuation of the command).  In other
++words, each test program invocation is 'wrapped up' inside an explicit
++invocation of the dynamic linker, which must itself execute the test
++program, having loaded shared libraries from the appropriate
++directories.
++
++To support cross-testing, EGLIBC allows the developer to optionally
++set the 'cross-test-wrapper' Make variable to another wrapper command,
++to which it passes the entire dynamic linker invocation shown above as
++arguments.  For example, if the developer supplies a wrapper of
++'my-wrapper hostname', then EGLIBC would run the test above as
++follows:
++
++    $ my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++The 'my-wrapper' command is responsible for executing the command
++given on the host system.
++
++Since tests are run in varying directories, the wrapper should either
++be in your command search path, or 'cross-test-wrapper' should give an
++absolute path for the wrapper.
++
++The wrapper must meet several requirements:
++
++- It must preserve the current directory.  As explained above, the
++  build directory tree must be visible on both the build and host
++  systems, at the same path.  The test wrapper must ensure that the
++  current directory it inherits is also inherited by the dynamic
++  linker (and thus the test program itself).
++
++- It must preserve environment variables' values.  Many EGLIBC tests
++  set environment variables for test runs; in native testing, it
++  invokes programs like this:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  With the cross-testing wrapper, that invocation becomes:
++
++    $ GCONV_PATH=$objdir/iconvdata \
++      my-wrapper hostname \
++      $objdir/elf/ld-linux.so.3 --library-path $objdir \
++      ./tst-foo arg1 arg2
++
++  Here, 'my-wrapper' must ensure that the value it sees for
++  'GCONV_PATH' will be seen by the dynamic linker, and thus 'tst-foo'
++  itself.  (The wrapper supplied with GLIBC simply preserves the
++  values of *all* enviroment variables, with a fixed set of
++  exceptions.)
++
++  If your wrapper is a shell script, take care to correctly propagate
++  environment variables whose values contain spaces and shell
++  metacharacters.
++
++- It must pass the command's arguments, unmodified.  The arguments
++  seen by the test program should be exactly those seen by the wrapper
++  (after whatever arguments are given to the wrapper itself).  The
++  EGLIBC test framework performs all needed shell word splitting and
++  expansion (wildcard expansion, parameter substitution, and so on)
++  before invoking the wrapper; further expansion may break the tests.

++The 'cross-test-ssh.sh' script
++
++If you want to use 'ssh' (or something sufficiently similar) to run
++test programs on your host system, EGLIBC includes a shell script,
++'scripts/cross-test-ssh.sh', which you can use as your wrapper
++command.  This script takes care of setting the test command's current
++directory, propagating environment variable values, and carrying
++command-line arguments, all across an 'ssh' connection.  You may even
++supply an alternative to 'ssh' on the command line, if needed.
++
++For more details, pass 'cross-test-ssh.sh' the '--help' option.
++
++
++The Cross-Compiling Locale Definition Command
++
++Some EGLIBC tests rely on locales generated especially for the test
++process.  In a native configuration, these tests simply run the
++'localedef' command built by the normal EGLIBC build process,
++'locale/localedef', to process and install their locales.  However, in
++a cross-compiling configuration, this 'localedef' is built for the
++host system, not the build system, and since it requires quite a bit
++of memory to run (we have seen it fail on systems with 64MiB of
++memory), it may not be practical to run it on the host system.
++
++If set, EGLIBC uses the 'cross-localedef' Make variable as the command
++to run on the build system to process and install locales.  The
++localedef program built from the EGLIBC 'localedef' module is
++suitable.
++
++The value of 'cross-localedef' may also include command-line arguments
++to be passed to the program; if you are using EGLIBC's 'localedef',
++you may include endianness and 'uint32_t' alignment arguments here.
++
++
++Example
++
++In developing EGLIBC's cross-testing facility, we invoked 'make' with
++the following script:
++
++    #!/bin/sh
++
++    srcdir=...
++    test_hostname=...
++    localedefdir=...
++    cross_gxx=...-g++
++
++    wrapper="$srcdir/scripts/cross-test-ssh.sh $test_hostname"
++    localedef="$localedefdir/localedef --little-endian --uint32-align=4"
++
++    make cross-test-wrapper="$wrapper" \
++         cross-localedef="$localedef" \
++         CXX="$cross_gxx" \
++         "$@"
++
++
++Other Cross-Testing Concerns
++
++Here are notes on some other issues which you may encounter in running
++the EGLIBC tests in a cross-compiling environment:
++
++- Some tests require a C++ cross-compiler; you should set the 'CXX'
++  Make variable to the name of an appropriate cross-compiler.
++
++- Some tests require access to libstdc++.so.6 and libgcc_s.so.1; we
++  simply place copies of these libraries in the top EGLIBC build
++  directory.

+The default lib search path order is:
+
+  1) LD_LIBRARY_PATH
+  2) RPATH from the binary
+  3) ld.so.cache
+  4) default search paths embedded in the linker
+
+For nativesdk binaries which are being used alongside binaries on a host system, we 
+need the search paths to firstly search the shipped nativesdk libs but then also
+cover the host system. For example we want the host system's libGL and this may be
+in a non-standard location like /usr/lib/mesa. The only place the location is know 
+about is in the ld.so.cache of the host system.
+
+Since nativesdk has a simple structure and doesn't need to use a cache itself, we 
+repurpose the cache for use as a last resort in finding host system binaries. This 
+means we need to switch the order of 3 and 4 above to make this work effectively.

++#           Multi-line help explaining the option group's meaning in

++#
++# defines an option group whose variable is GROUP_NAME, with
++# meaningful values 'y' (enabled) and 'n' (disabled).  The
++# documentation is formatted to be consumed by some sort of
++# interactive configuration interface, but EGLIBC doesn't have such an
++# interface yet.
++#
++# An option may have a 'depends on' line, indicating which other options
++# must also be enabled if this option is.  At present, EGLIBC doesn't
++# check that these dependencies are satisfied.
++#
++# Option group variables get their default values from the file
++# 'option-groups.defaults', in the top directory of the EGLIBC source
++# tree.  By default, all EGLIBC option groups are enabled --- their
++# variables are set to 'y'.
++#
++# After including 'option-groups.defaults', the EGLIBC make machinery
++# includes the file 'option-groups.config' from the top of the build
++# tree, if it is present.  Developers can place assignments to option
++# group variables in that file to override the defaults.  For example,
++# to disable an option group, place a line of the form:
++#
++#    OPTION_GROUP_NAME = n
++#
++# in 'option-groups.config' at the top of your build tree.  To
++# explicitly enable an option group, you may also write:
++#
++#    OPTION_GROUP_NAME = y
++#
++# although this simply reestablishes the value already set by
++# 'option-groups.defaults'.

++
++          The EGLIBC source tree includes a sample configuration file
++          named 'nss/fixed-nsswitch.conf'; for simple configurations,
++          you will probably want to delete references to databases not
++          needed on your system.
++
++config EGLIBC_NSSWITCH_FIXED_FUNCTIONS
++   string "Nsswitch fixed functions filename"
++   depends on !EGLIBC_NSSWITCH
++   default ""
++   help
++          The EGLIBC build process uses this file to decide which
++          functions to make available from which service libraries.
++          The file 'nss/fixed-nsswitch.functions' serves as a sample
++          configuration file for this setting, and explains its syntax
++          and meaning in more detail.
++
++          This should be an absolute file name.  The EGLIBC build
++          process may use it from several different working
++          directories.  It may include references to Makefile
++          variables like 'common-objpfx' (the top of the build tree,
++          with a trailing slash), or '..' (the top of the source tree,
++          with a trailing slash).
++
++          Be sure to mention each function in each service you wish to
++          use.  If you do not mention a service's function here, the
++          EGLIBC database access functions will not find it, even if
++          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
++          file.
++
++          In this arrangement, EGLIBC will not use the 'dlopen' and
++          'dlsym' functions to find database access functions.  Instead,
++          libc hard-codes references to the service libraries' database
++          access functions.  You must explicitly link your program
++          against the name service libraries (those whose names start
++          with 'libnss_', in the sysroot's '/lib' directory) whose
++          functions you intend to use.  This arrangement helps
++          system-wide static analysis tools decide which functions a
++          system actually uses.
++
++          Note that some nsswitch service libraries require other option
++          groups to be enabled; for example, the EGLIBC_INET
++          option group must be enabled to use the 'libnss_dns.so.2'
++          service library, which uses the Domain Name System network
++          protocol to answer queries.
++
++config EGLIBC_RCMD

++          freopen64
++
++        These functions all take an OPENTYPE parameter which may
++        contain a string of the form ",ccs=CHARSET", indicating that
++        the underlying file uses the character set named CHARSET.
++        This produces a wide-oriented stream, which is only useful
++        when the functions included in this option group are present.
++        If the user attempts to open a file specifying a character set
++        in the OPENTYPE parameter, and EGLIBC was built with this
++        option group disabled, the function returns NULL, and sets
++        errno to EINVAL.

++              The EGLIBC Component Configuration System
++                  Jim Blandy <jimb@codesourcery.com>
++
++Introduction
++
++The GNU C library (GLIBC) provides a broad range of functionality,
++ranging from internationalization support to transcendental
++mathematical functions.  Its website boasts that "nearly all known and
++useful functions from any other C library are available."  This
++exhaustive approach has been one of GLIBC's strengths on desktop and
++server systems, but it has also given GLIBC a large footprint, both in
++memory and on disk, making it a challenge to use in embedded systems
++with limited resources.
++
++The Embedded GNU C library (EGLIBC) is a variant of the GNU C library
++designed to work well on embedded systems.  In particular, EGLIBC's
++component configuration system allows embedded developers to build
++customized versions of the library that include only the features
++their application uses, reducing its space requirements.
++
++EGLIBC's component configuration system categorizes the library's
++functions into "option groups", and allows you to include or exclude
++option groups individually.  Some option groups depend on others;
++EGLIBC tracks these relationships, and ensures that the selected
++configuration yields a functioning library.
++
++
++Consistent and Predictable Behavior
++
++A flexible configuration system is a mixed blessing: if the options
++offered are poorly designed, it can be hard to see which choices will
++have the desired effects, and choices with obscure consequences can
++make debugging difficult.  EGLIBC's configuration follows some general
++principles to reduce these risks:
++
++- EGLIBC has a single default configuration for each target
++  architecture.
++
++- In the default configuration, all option groups are enabled, and
++  EGLIBC is upwardly API- and ABI-compatible with GLIBC.
++
++- As much as possible, configurations only affect what functions are
++  present, not how they behave.  If the system works with an option
++  group disabled, it will still work with it enabled.
++
++- As much as possible, configurations only select option groups ---
++  they do not describe characteristics of the target architecture.
++
++These rules mean that you have a simple debugging strategy available
++if you suspect that your EGLIBC configuration might be the source of a
++problem: fall back to the default configuration, re-test, and then
++disable option groups one by one, until the problem reappears.
++
++
++The Option Groups
++
++To see the current full list of implemented option groups, refer to the
++file 'option-groups.def' at the top of the source tree, or run
++'make menuconfig' from the top-level build directory.
++
++The POSIX.1-2001 specification includes a suggested partition of all
++the functions in the POSIX C API into option groups: math functions
++like 'sin' and 'cos'; networking functions like 'socket' and
++'connect'; and so on.  EGLIBC could use this partitioning as the basis
++for future option groups.
++
++
++Implementation
++
++The EGLIBC component configuration system resembles the approach used
++by the Linux kernel to select device drivers, network protocols, and
++other features.  A file named 'option-groups.config' in the top-level
++build directory contains assignments to Make variables, each of which
++enables or disables a particular option group.  If the variable's
++value is set to 'y', then the option group is enabled; if it set to
++anything else, the option group is omitted.  The file
++'option-groups.defaults', at the top of the source tree, establishes
++default values for all variables; all option groups are enabled by
++default.
++
++For example, the following 'option-groups.config' would omit locale
++data, but include mathematical functions, and everything else:
++
++   OPTION_EGLIBC_LOCALES = n
++   OPTION_EGLIBC_LIBM = y
++
++Like the Linux kernel, EGLIBC supports a similar set of '*config' make
++targets to make it easier to create 'option-groups.config', with all
++dependencies between option groups automatically satisfied.  Run
++'make help' to see the list of supported make config targets.  For
++example, 'make menuconfig' will update the current config utilising a
++menu based program.
++
++The option group names and their type (boolean, int, hex, string), help
++description, and dependencies with other option groups, are described by
++'option-groups.def' at the top of the source tree, analogous to the
++'Kconfig' files in the Linux kernel.
++
++In general, each option group variable controls whether a given set of
++object files in EGLIBC is compiled and included in the final
++libraries, or omitted from the build.
++
++Each subdirectory's Makefile categorizes its routines, libraries, and
++executables by option group.  For example, EGLIBC's 'math/Makefile'
++places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows:
++
++   extra-libs-$(OPTION_EGLIBC_LIBM) := libm
++
++Finally, common code in 'Makerules' cites the value of the variable
++'extra-libs-y', selecting only those libraries that belong to enabled
++option groups to be built.
++
++
++Current Status and Future Directions
++
++The EGLIBC component configuration system described here is still
++under development.
++
++We have used the system to subset some portions of EGLIBC's

+Upstream-Status: Inappropriate [SDK specific]

+This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings
+and lengths as well as ld.so.cache path in the dynamic loader to specific
+sections in memory. The sections that contain paths have been allocated a 4096
+byte section, which is the maximum path length in linux. This will allow the

+Upstream-Status: Inappropriate [SDK specific]
+
+eglibc-nativesdk: Fix buffer overrun with a relocated SDK
+
+When ld-linux-*.so.2 is relocated to a path that is longer than the
+original fixed location, the dynamic loader will crash in open_path
+because it implicitly assumes that max_dirnamelen is a fixed size that
+never changes.
+
+The allocated buffer will not be large enough to contain the directory
+path string which is larger than the fixed location provided at build
+time.
