++*********************************************************************
++
++This package contains my ELF dynamic linkers (ld-linux.so.1), dynamic
++linker library (libdl.so.1) and utilities (ldconfig and ldd) for Linux.
++
++You need Linux kernel 2.0.0 or later with ELF support compiled in
++(i.e. not loaded as a module) to use this package.
++
++The dynamic linker is used to bootstrap programs and load shared
++libraries at startup. The dynamic linker library is used to
++dynamically load shared libraries after a program is running.
++Ldconfig is used to automatically update the symbolic links to shared
++libraries and build the cache file used by the dynamic linker. Ldd is
++used to list the shared libraries used by a program.
++
++Please see the included manual pages for further details.
++
++To install, simply run "sh instldso.sh" as root. Ready-to-go versions
++of all end-products are provided so nothing should need to be compiled
++or linked. If you are still using libc5 as your primary development
++library, you should use the "--devfiles" option when running
++instldso.sh to install the file needed to compile with libdl.
++
++ELF versions of gcc, binutils and libc are now required to compile
++everything, including the old, unsupported, a.out dynamic linker.
++Finally, an optimization level of O2 or higher must be used to compile
++ld-linux.so and libdl.so due the use of inline functions.
++
++Notable contributors to this package include Eric Youngdale, Peter
++MacDonald, Hongjiu Lu, Linus Torvalds, Lars Wirzenius, Mitch D'Souza,
++Rik Faith, Andreas Schwab and Adam Richter (not necessarily in that
++order).
++
++###################### IMPORTANT NOTICES #############################
++
++A.OUT SUPPORT:
++
++As of ld.so-1.9.0, the old, a.out dynamic loader is no longer
++officially supported. The code is still included and built, but I
++make no promises that it will work. I will accept patches for it,
++but they will not be tested by me.
++
++GLIBC (AKA LIBC6) SUPPORT:
++
++As of ld.so-1.9.0, the main focus of this package is to ease the
++transition to libc6. No significant, new features are expected to be
++added. If you need new features, switch to libc6.
++
++Except for libpthread.so, the sonames of the core libraries provided
++with libc6 have been chosen so they do not conflict with those
++provided by libc5 and ld.so. However, the current plan is not use
++new, nonconflicting sonames for other libraries such as ncurses and
++X11. This presents two problems. First, libraries using the same
++soname for both libc5 and libc6 can not be placed in the same
++directory. Second, the dynamic linkers need to make sure not to load
++a library for the wrong version of libc.
++
++The first problem is easy. Just move the old, libc5-based libraries
++to new directories (e.g. /lib/libc5-compat, /usr/lib/libc5-compat,
++etc.) and add those directories to /etc/ld.so.conf. Then install the
++new, libc6-based versions in the standard places.
++
++The second problem is more difficult. Ideally, the dynamic linkers
++would be changed to perform a complete dependency analysis on every
++library to be loaded to make sure the wrong versions aren't used.
++This approach doesn't seem worth the added complexity, especially
++since we now have symbol versioning for ELF libraries. Instead a
++simpler approach will be used, at least initially.
++
++Ldconfig has been modified to perform a (currently simple) dependency
++analysis on libraries and to store an indication in /etc/ld.so.cache
++of whether a library is for libc5, libc6 or an unknown libc. The
++dynamic linkers then only need to make a simple check at run-time to
++make sure they don't load the wrong version of a library.
++
++The dynamic linker for libc5 provided in this package, has already
++been modified to use the new information in /etc/ld.so.cache. For
++glibc versions 2.0.1 and earlier, the dynamic linker for libc6 needs
++the patch contained in glibc.patch. You should apply the patch and
++rebuild glibc before using the new ldconfig.
++
++As stated above, the dependency analysis currently done by ldconfig is
++rather simple. Basically, it looks for the sonames used by the
++various versions of libc, libm and libdl. For any approach using a
++dependency analysis such as this to work, it is very important that
++shared libraries be built with complete dependency information. This
++can be done by using the appropriate -l options when running 'gcc
++-shared'. For example, when building libfoo.so which depends on libc
++and libbar, you should add -lbar and -lc gcc command line.
++
++######################################################################
++

++ undefined symbol could cause a segfault.
++
++ Added a clarification for LD_PRELOAD to the ld.so manual
++ page and added a symlink for ld-linux.so (Bug#33123).
++
++ Don't install ldd for Debian except for the m68k arch
++ because glibc 2.1 now includes it (Bug#35458).
++
++Changes in version 1.9.10:
++
++ Changed ldconfig to issue a warning and not overwrite a
++ regular file with a symlink (Bug#30859).
++
++ Changed Debian packaging to conflict with and replace the
++ ldconfig package (Bug#29398).
++
++Changes in version 1.9.9:
++
++ Changed ld-linux.so and libdl.so to match glibc by not
++ allowing user preloads of system libraries into setu/gid
++ binaries unless the library itself is setuid.
++
++ Fixed problems in ld-linux.so on the sparc architecture
++ (Juan Cespedes).
++
++Changes in version 1.9.8:
++
++ Changed ldconfig to allow the expected type for all
++ libraries in a directory to be optionally specified
++ (Mark Phillips). See the ldconfig man page.

++
++ Fixed a bug in ldconfig when the -l option was used on a
++ filename without a '/' in it.
++
++ Updated the man pages (Bug#6404, Bug#9721, Bug#10652,
++ Bug#13494 and Bug#14127). They could still use some work.
++
++ No longer install the info page since it's way out of date.
++
++ Fixed minor Debian packaging problems (Bug#13160,
++ Bug#15577 and Bug#19345).
++
++Changes in version 1.9.6:

++
++ Changed ld-linux.so to be compilable with gcc 2.8.0 (Sven
++ Verdoolaege)

++ correctly when run on shared libraries.
++
++ Fixed a problem in the previous version where some
++ Makefiles were not architecture independent.
++
++Changes in version 1.9.4:
++
++ Fixed a bug in ld.so introduced in the previous version
++ which broke preloads.
++
++ Turned a.out support back on by default, at least for the
++ time being. There are no promises to keep it.
++
++Changes in version 1.9.3:
++
++ Fixed buffer overflow bugs in ld-linux.so and ld.so.
++
++ Changed the README file a little to clarify a couple of
++ things.
++
++ Changed ldconfig to chroot to the specified directory when
++ the new -r option is used (Bob Tinsley).
++
++Changes in version 1.9.2:
++
++ Removed /usr/local/lib from the default /etc/ld.so.conf
++ for Debian (Bug#8181).
++
++ Changed ldconfig to be 64-bit clean (H.J. Lu).
++
++Changes in version 1.9.1:
++
++ Changed ldconfig to try to determine which libc a

++
++ Fixed a bug in ldconfig where an older library using
++ the glibc naming convention would be used instead of
++ a newer library.
++
++ Changed to ld-linux.so and libdl.so to not require the

++ available, when run on a shared library.
++
++ Changed ld-linux.so to print the load addresses of
++ libraries, ala glibc, when run by ldd.
++
++ Changed ld-linux.so to allow the libraries listed in
++ LD_PRELOAD to be separated by white space in addition to
++ colons.
++

++ LD_PRELOAD for setu/gid programs as long as they can be
++ loaded securely.
++
++ Changed ldconfig to update the symlinks for the dynamic
++ linkers.
++
++ Changed ldconfig to try to determine if an ELF library is

++ cache. The mechanism used is rather simplistic and may
++ need to be enhanced.
++
++ Changed ldconfig to print the type of ELF library when
++ printing the cache.

++ instead of a regular file.
++
++ Fixed a Debian packaging problem for the sparc
++ architecture.

++ Minor documentation updates to reflect recent changes.
++
++ Changed ld.so and ld-linux.so to perform more complete
++ validation on ld.so.cache before using it.

++ Changed ldconfig to accept libraries with inconsistent
++ sonames since glibc is going to use them. A warning is
++ still printed in debug mode.
++
++ Changed the install script to not strip _dl_debug_state
++ from ld-linux.so since gdb needs it.
++
++ More sparc fixes (Derrick Brashear).
++
++ Changed ldconfig to not issue a warning when a linker
++ script disguised as a shared library is found.
++
++ Fixed a bug in ld-linux.so where some registers were
++ not preserved on the first call to a function causing
++ problems for non-C-like languages (Tim Renouf).
++
++ Fixed a bug in ld-linux.so where global variables were
++ not always mapped correctly across dynamically loaded
++ libraries (Mikihiko Nakao).
++
++ Converted to new Debian source packaging format (Shaya
++ Potter).
++
++Changes in version 1.8.6/7:
++
++ Never released as some unofficial patches used these
++ version numbers.
++

++ Changed ld-linux.so back to not keep ld.so.cache mapped
++ at all times.
++
++ Changed Debian packaging to compress man pages, strip all
++ binaries (Bug#5125) and include a shlibs file.
++
++Changes in version 1.8.3:
++
++ Changed ld-linux.so to process LD_PRELOAD before
++ /etc/ld.so.preload.

++ Deutschmann).
++
++ Minor sparc and installation changes (Elliot Lee).
++
++ Added multiple architecture support for Debian (Leland
++ Lucius).
++
++ Changed libdl to better support RTLD_NEXT (Eric
++ Youngdale). Note: the exact meaning of ETLD_NEXT is
++ still not clear in all cases.
++
++ Removed some libc dependencies from libdl. Still need
++ to remove malloc and free.
++
++Changes in version 1.8.1:
++
++ Changed ld.so to be compiled as ELF. This also means
++ that ELF support is now required. A.out support is
++ still optional.
++
++ Changed ld-linux.so and libdl.so to use the rpath in the
++ executable instead of in the invoking shared library.
++
++ More m68k fixes (Andreas Schwab).

++ Changed ldcnnfig to ignore libraries ending in '~'.
++
++ Changed ldconfig to allow alternative conf and cache
++ files to be specified on the command-line.

++ handle pointer.
++
++Changes in version 1.8.0:
++
++ Changed ld-linux.so to be more liberal when checking to

++
++ Various m68k fixes (Andreas Schwab).
++
++ Changed ld.so to only use LD_AOUT_LIBRARY_PATH and
++ LD_AOUT_PRELOAD and ld-linux.so to only use
++ LD_LIBRARY_PATH and LD_PRELOAD. LD_ELF_LIBRARY_PATH
++ and LD_ELF_PRELOAD are no longer supported.
++
++ Changed ld-linux.so to allow debugging of shared and
++ dynamically loaded libraries (H.J. Lu, Andreas Schwab).
++
++ Changed ld-linux.so to preload ELF shared libraries
++ listed in /etc/ld.so.preload. This allows secure
++ preloads, even for setuid/setgid programs.
++
++ Changed ld-linux.so to keep ld.so.cache mapped at all
++ times.
++
++ Changed ldconfig to allow #-style comments in ld.so.conf.
++
++ Removed various compiler warnings (Richard Sladkey and
++ David Engel).
++
++ Changed ldd to work on ELF shared libraries. This may
++ need a little more work.
++
++Changes in version 1.7.14:
++
++ Changed ldconfig to recognize ELF shared libraries
++ generated by post-2.6 versions of ld (Andreas Schwab).
++
++ Changed ldconfig to not remove stale links that do not
++ have a version number since they may be needed by ld.
++
++Changes in version 1.7.13:
++
++ Fixed a problem in ld-linux.so where a program linked
++ with a shared library that was not used could result in
++ a segmentation fault (H.J. Lu).
++
++Changes in version 1.7.12:
++
++ Fixed a problem in libdl.so where the wrong library
++ could be marked as global when RTLD_GLOBAL was used
++ (Lars Heete).
++
++ Installed dlfcn.h with libdl.so instead of requiring
++ it to be supplied with libc.
++
++ Removed support for libldso.a since it was nearly
++ impossible to use anyway.
++
++ Changed ldd to detect when the program being checked
++ exited abnormally.
++
++Changes in version 1.7.11:
++
++ Changed ld.so and ld-linux.so to delete all variations
++ of LD_PRELOAD and LD_LIBRARY_PATH for set[ug]id programs,
++ This makes it harder for broken set[ug]id programs to be
++ compromised.
++
++ Fixed a problem in libdl.so where dlsym would not accept
++ the handle returned from dlopen(0, *).
++
++Changes in version 1.7.10:
++
++ Changed ld-linux.so and libdl.so to support RTLD_GLOBAL
++ (Eric Youngdale).
++
++Changes in version 1.7.9:
++
++ Fixed a problem in ld-linux.so in detecting when the
++ new user/group information is provided by the kernel.
++
++ Fixed a problem in ld-linux.so where a buffer could be
++ overflowed if a large number of libraries were loaded
++ (Thomas Moore).
++
++Changes in version 1.7.8:
++
++ Changed the Makefiles and install scripts to support
++ a.out- and ELF-only configurations.
++
++ Changed ld-linux.so to use the user/group information
++ provided by linux 1.3.23+ instead of making syscalls
++ to get it.
++
++ Changed libdl.so to support RTLD_NEXT (Glenn Fowler).
++
++ Changed libdl.so to only execute the fini sections
++ instead of completely closing libraries at exit (Glenn
++ Fowler).
++
++ Changed ld.so and ld-linux.so to print the required
++ cache version when a mismatch is detected.
++
++ Changed ld-linux.so to not require on /dev/zero (Ralph
++ Loader).
++
++ Minor m68k cleanups (Andreas Schwab).
++
++Changes in version 1.7.7:
++
++ Fixed problems compiling with recent 1.3.x kernels.
++
++ Changed ld-linux.so to not use MAP_DENYWRITE until the
++ permission issue regarding it is resolved.
++
++Changes in version 1.7.6:
++
++ Fixed a bug in ld-linux.so dealing with a zero-length
++ LD_{ELF_}PRELOAD.
++
++ Changed ld.so and ld-linux.so to truncate all variations
++ of LD_PRELOAD and LD_LIBRARY_PATH for set[ug]id programs.
++
++Changes in version 1.7.5:
++
++ Changed ldconfig to recognize libraries without any
++ version number (eg. libXYZ.so).
++
++ Changed ldconfig to not generate a corrupt cache when
++ the disk is full or other write errors occur.
++
++ Changed ld-linux.so to map files with MAP_DENYWRITE to
++ keep them from being changed while the file is in use
++ (Rick Sladkey).
++
++ Changed libdl to not overwrite the scope pointer of a
++ library if it was already loaded (H.J. Lu).
++
++ Changed ld-linux.so so gdb can be used on constructors
++ (Eric Youngdale).
++
++ Changed ldconfig to ignore ELF libraries where the soname
++ does not match the file name on the assumption that it is
++ a used at compile-time (eg. libcurses.so -> libncruses.so).
++
++Changes in version 1.7.4:
++
++ Changed ld-linux.so and libdl to use the appropriate
++ rpaths when searching for shared libraries (Eric
++ Youngdale).
++
++ Changed ld-linux.so to search rpath before using the
++ cache. This more closely conforms to the IBCS standard.
++
++Changes in version 1.7.3:
++
++ Changed ld-linux.so to only print a library name the
++ first time it is loaded when run from ldd.
++
++ Fixed a bug in ldconfig where an invalid cache could be
++ generated if a directory was specified multiple times in
++ ld.so.conf.
++
++ Changed ld-linux.so so it will return the address of a
++ weak symbol when called from dlsym in libdl (Eric
++ Youngdale.
++
++Changes in version 1.7.2:
++
++ Changed libdl.so again to fix the undefined foobar
++ problem.
++
++Changes in version 1.7.1:
++
++ Changed libdl so it will compile at optimization level
++ O3 or higher.
++
++ Changed ldconfig to always create the cache file with
++ mode 644.
++
++ Changed ldconfig to not ingore valid symlinks.
++
++ Changed ldconfig to use the library name as the soname
++ for ELF libraries that do not have an soname entry.
++
++ Changed ld-linux.so to print the actual, requested library
++ name at the time it is loaded instead of trying to figure
++ it out after the fact.
++
++Changes in version 1.7.0:
++
++ Changed ldconfig to read the actual soname from the image
++ for ELF libraries and make it available to ld-linux.so.
++ The soname for DLL libraries is still determined by
++ truncating the minor numbers from the image file name.
++
++ Changed ldconfig to no longer support the undocumented
++ sort options.
++
++ Changed ld.so to require a valid cache to find libraries
++ in directories specified in ld.so.conf. /usr/lib and /lib
++ are still searched as a last resort. Ld-linux.so already
++ operated this way.
++
++ Fixed a bug in libldso.a where the arguments to
++ shared_loader were not parsed correctly (Wolfram Gloger).
++
++ Added support for RELA-style relocations under Linux/68k
++ (Andreas Schwab).
++
++ Changed ld-linux.so to only map the cache once for all
++ libraries instead of individually for each library.
++
++ Changed ld-linux.so continue searching the cache instead of
++ giving up when failing to load the first entry found.
++
++ Changed ld-linux.so to produce output similar to ld.so when
++ run from ldd or when errors occur.
++
++Changes in version 1.6.7:
++
++ Changed the install scripts to make sure that ld.so and
++ ld-linux.so are always usable.
++
++ Added support for Linux/Sparc (Eric Youngdale).
++
++ Added support for Linux/68k (Andreas Schwab).
++
++ Fixed various bugs in ld-linux.so dealing with closing
++ files, unmapping memory, dereferencing NULL pointers and
++ printing library names (David Engel, Eric Youngdale and
++ Andreas Schwab).
++
++ Replaced the manual page for libdl with a freely
++ distributable one (Adam Richter).
++
++ Fixed a bug in ld-linux.so where LD_LIBRARY_PATH and
++ LD_PRELOAD were not cleared for setuid/setgid programs.
++
++ Fixed a bug in libdl where dlsym would not return the
++ correct address of a symbol if it was redefined in another
++ library (Oleg Kibirev).
++
++ Changed ld-linux.so to use the following order to search
++ for libraries: LD_{ELF_}LIBRARY_PATH, ld.so.cache, rpath,
++ /usr/lib and /lib.
++
++ Changed ld-linux.so to not needlessly allocate memory when
++ using ld.so.cache.
++
++Changes in version 1.6.6:
++
++ Changed ldconfig to not warn about removing stale links
++ unless the -v option is specified.
++
++ Added manual pages for libdl (from FreeBSD/Sun)
++
++ Fixed a bug in ld.so dealing with preloading of objects
++ generated by recent versions of ld (Mitch D'Souza).
++
++ Fixed bugs in ldd where some errors were either not
++ detected or not printed.
++
++ Fixed a bug in ld-linux.so where the trailing nul in a
++ library name was not being copied (Owen Taylor).
++
++Changes in version 1.6.5:
++
++ Changed ldconfig to remove stale symbolic links.
++
++ Added debug hooks in ld-linux.so and libdl.so to be used
++ by a future version of gdb (Eric Youngdale).
++
++Changes in version 1.6.4:
++
++ Change ld-linux.so to print on stdout instead of stderr
++ when run from ldd.
++
++ Added support for Debian GNU/Linux packaging.
++
++Changes in version 1.6.3:
++
++ Fixed a bug in libdl when closing a library (H.J. Lu).
++
++Changes in version 1.6.2:
++
++ Changed the error message printed by ldd when a file is
++ not a.out or ELF. It used to only list a.out formats.
++
++ Changed ldconfig to no longer cache and set up links for
++ ld-linux.so.
++
++ Changed ld-linux.so and libdl to not conflict with upcoming
++ changes in kernel header files.
++
++ Changed ld-linux.so to not print preloaded libraries.
++
++Changes in version 1.6.1:
++
++ Updated the installation script.
++
++ Changed ld.so and ld-linux.so to look for LD_AOUT_PRELOAD
++ and LD_ELF_PRELOAD, respectively, before LD_PRELOAD.
++
++ Changed ld.so and ld-linux.so to use LD_AOUT_LIBRARY_PATH
++ and LD_ELF_LIBRARY_PATH, respectively, instead of
++ AOUT_LD_LIBRARY_PATH and ELF_LD_LIBRARY_PATH.
++
++Changes in version 1.6.0:
++
++ Changed ldconfig to process libraries which do not have
++ a minor version or patch level number.
++
++ Incorporated ld-linux.so and libdl.so.
++
++ Changed ld.so and ld-linux.so to not miss entries in the
++ cache when the fully qualified library is requested.
++
++ Changed ldconfig to use stdout instead of stderr when
++ printing the cache.
++
++Changes in version 1.5.3:
++
++ LD_PRELOAD enhancements (Tristan Gigold).
++
++ LD_PRELOAD patch for linux-68k (Andreas Schwab).
++
++Changes in version 1.5.2:
++
++ More ELF changes (Mitch D'Souza).
++
++ Changed ldconfig to also update the link for ld-linux.so.
++
++Changes in version 1.5.1:
++
++ More ELF and LD_PRELOAD changes (Mitch D'Souza).
++
++Changes in version 1.5.0:
++
++ Chnaged all executables to QMAGIC (Mitch D'Souza and Rick
++ Sladkey).
++
++ Added preliminary support for ELF to ldd and ldconfig (Eric
++ Youndale and H.J. Lu).
++
++ Added support for LD_PRELOAD to ld.so (Mitch D'Souza).
++
++ Removed the "advertising" clause from the copyright notices
++ in all source files.
++
++Changes in version 1.4.4:
++
++ Changed ldconfig to support QMAGIC libraries.
++
++ Fixed a bug in ld.so where some of the error messages had
++ transposed arguments.
++
++Changes in version 1.4.3:
++
++ Fixed an obscure bug in ld.so where an index was not being
++ incremented when a library was not found using the cache.
++
++Changes in version 1.4.2:
++
++ Changed ldconfig to issue a warning and continue instead
++ of an error and exiting when a link can't be updated.
++ This is useful when some libraries are imported on read-
++ only file systems, such as an NFS mounted /usr.
++
++ Changed ld.so to be more robust in searching for libraries.
++ A library is not considered found unless it can actually be
++ loaded. If a library is not found using the cache, the
++ standard directories are searched as in pre-cache versions.
++
++Changes in version 1.4.1:
++
++ Fixed minor Makefile problems.
++
++ Added support for linux-68k.
++
++ Fixed a bug in ld.so where libraries with absolute paths
++ were not handled correctly.
++
++ Changed ld.so to ignore the directory in the names of
++ shared libraries by default. This allows older libraries
++ with absolute paths, such as the XView libraries, to take
++ advantage of the cache support.
++
++ Added a minimal usage message to ldconfig.
++
++Changes in version 1.4:
++
++ Fixed bug in ld.so where minor version numbers were not
++ reported correctly when a minor version incompatibility
++ was found.
++
++ Fixed bug in ldconfig where libraries with subversion
++ numbers greater than 9 were not compared correctly.
++
++ Added Mitch D'Souza's support for suppressing warning
++ messages from ld.so about minor version incompatibilities.
++
++ Added Mitch D'Souza's support for using a cache to speed
++ up searching for libraries in the standard directories.
++
++ Added Mitch D'Souza's support for a debugging version of
++ ld.so. Link with -lldso if you think you are experiencing
++ dynamic linker problems.
++
++Changes in version 1.3:
++
++ Added support for libraries using absolute pathnames. If I
++ had known that the XView libraries used them, I would have
++ added this earlier.
++
++ Fixed a bug handling old libraries using a pathname beginning
++ with '/' or '/lib/'.
++
++Changes in version 1.2a:
++
++ Fixed a minor bug in ldd which caused all files, specifically
++ scripts, to be recognized as binaries. Thanks to Olaf Flebbe
++ for reporting it.

++ working. */
++
++/*
++ * The main trick with this program is that initially, we ourselves are
++ * not dynamicly linked. This means that we cannot access any global
++ * variables or call any functions. No globals initially, since the
++ * Global Offset Table (GOT) is initialized by the linker assuming a
++ * virtual address of 0, and no function calls initially since the
++ * Procedure Linkage Table (PLT) is not yet initialized.
++ *
++ * There are additional initial restrictions - we cannot use large
++ * switch statements, since the compiler generates tables of addresses
++ * and jumps through them. We can use inline functions, because these
++ * do not transfer control to a new address, but they must be static so
++ * that they are not exported from the modules. We cannot use normal
++ * syscall stubs, because these all reference the errno global variable
++ * which is not yet initialized. We can use all of the local stack
++ * variables that we want.
++ *
++ * Life is further complicated by the fact that initially we do not
++ * want to do a complete dynamic linking. We want to allow the user to
++ * supply new functions to override symbols (i.e. weak symbols and/or
++ * LD_PRELOAD). So initially, we only perform relocations for
++ * variables that start with "_dl_" since ANSI specifies that the user
++ * is not supposed to redefine any of these variables.
++ *
++ * Fortunately, the linker itself leaves a few clues lying around, and
++ * when the kernel starts the image, there are a few further clues.
++ * First of all, there is Auxiliary Vector Table information sitting on
++ * which is provided to us by the kernel, and which includes
++ * information about the load address that the program interpreter was
++ * loaded at, the number of sections, the address the application was
++ * loaded at and so forth. Here this information is stored in the
++ * array auxvt. For details see linux/fs/binfmt_elf.c where it calls
++ * NEW_AUX_ENT() a bunch of time....
++ *
++ * Next, we need to find the GOT. On most arches there is a register
++ * pointing to the GOT, but just in case (and for new ports) I've added
++ * some (slow) C code to locate the GOT for you.
++ *
++ * This code was originally written for SVr4, and there the kernel
++ * would load all text pages R/O, so they needed to call mprotect a
++ * zillion times to mark all text pages as writable so dynamic linking
++ * would succeed. Then when they were done, they would change the
++ * protections for all the pages back again. Well, under Linux
++ * everything is loaded writable (since Linux does copy on write
++ * anyways) so all the mprotect stuff has been disabled.
++ *
++ * Initially, we do not have access to _dl_malloc since we can't yet
++ * make function calls, so we mmap one page to use as scratch space.
++ * Later on, when we can call _dl_malloc we reuse this this memory.
++ * This is also beneficial, since we do not want to use the same memory
++ * pool as malloc anyway - esp if the user redefines malloc to do
++ * something funky.
++ *
++ * Our first task is to perform a minimal linking so that we can call
++ * other portions of the dynamic linker. Once we have done this, we
++ * then build the list of modules that the application requires, using
++ * LD_LIBRARY_PATH if this is not a suid program (/usr/lib otherwise).
++ * Once this is done, we can do the dynamic linking as required, and we
++ * must omit the things we did to get the dynamic linker up and running
++ * in the first place. After we have done this, we just have a few
++ * housekeeping chores and we can transfer control to the user's
++ * application.

++Almost all of the code present in these source files was taken
++from GLIBC. In the descriptions below, all files mentioned are
++with respect to the top level GLIBC source directory accept for
++code taken from the Linux kernel.
++
++boot1_arch.h
++------------
++Contains code to fix up the stack pointer so that the dynamic
++linker can find argc, argv and Auxillary Vector Table (AVT).
++The code is taken from the function 'RTLD_START' in the file
++'sysdeps/mips/dl-machine.h'.
++
++elfinterp.c
++-----------
++Contains the runtime resolver code taken from the function
++'__dl_runtime_resolve' in 'sysdeps/mips/dl-machine.h'. Also
++contains the function to perform relocations for objects
++other than the linker itself. The code was taken from the
++function 'elf_machine_rel' in 'sysdeps/mips/dl-machine.h'.
++
++ld_syscalls.h
++-------------
++Used to contain all the macro functions for the system calls
++as well as the list of system calls supported. We now include
++<sys/syscall.h> but with the __set_errno macro defined empty
++so we can use the same file for the linker as well as userspace.
++Original code was taken from the Linux kernel source 2.4.17 and
++can be found in the file 'include/asm-mips/unistd.h'.
++
++ld_sysdep.h
++-----------
++Contains bootstrap code for the dynamic linker, magic numbers
++for detecting MIPS target types and some macros. The macro
++function 'PERFORM_BOOTSTRAP_GOT' is used to relocate the dynamic
++linker's GOT so that function calls can be made. The code is
++taken from the function 'ELF_MACHINE_BEFORE_RTLD_RELOC' in the
++file 'sysdeps/mips/dl-machine.h'. The other macro function
++'PERFORM_BOOTSTRAP_RELOC' is used to do the relocations for
++the dynamic loader. The code is taken from the function
++'elf_machine_rel' in the file 'sysdeps/mips/dl-machine.h'. The
++final macro function is 'INIT_GOT' which initializes the GOT
++for the application being dynamically linked and loaded. The
++code is taken from the functions 'elf_machine_runtime_setup'
++and 'elf_machine_got_rel' in 'sysdeps/mips/dl-machine.h'.
++
++resolve.S
++---------
++Contains the low-level assembly code for the dynamic runtime
++resolver. The code is taken from the assembly code function
++'_dl_runtime_resolve' in the file 'sysdeps/mips/dl-machine.h'.
++The code looks a bit different since we only need to pass the
++symbol index and the old GP register.

++dlclose, dlerror, dlopen, dlsym \- Programming interface to dynamic linking loader.
++.SH SYNOPSIS
++.B #include <dlfcn.h>
++.sp
++.BI "void *dlopen (const char *" "filename" ", int " flag ");
++.br
++.BI "const char *dlerror(void);"
++.br
++.BI "void *dlsym(void *"handle ", char *"symbol ");"
++.br

++.sp
++Special symbols:
++.BR "_init" ", " "_fini" ". "
++.SH DESCRIPTION
++.B dlopen
++loads a dynamic library from the file named by the null terminated
++string
++.I filename
++and returns an opaque "handle" for the dynamic library.
++If
++.I filename
++is not an absolute path (i.e., it does not begin with a "/"), then the
++file is searched for in the following locations:
++.RS
++.PP
++A colon-separated list of directories in the user's
++\fBLD_LIBRARY\fP path environment variable.
++.PP
++The list of libraries specified in \fI/etc/ld.so.cache\fP.
++.PP
++\fI/usr/lib\fP, followed by \fI/lib\fP.
++.RE
++.PP
++If
++.I filename
++is a NULL pointer, then the returned handle is for the main program.
++.PP
++External references in the library are resolved using the libraries
++in that library's dependency list and any other libraries previously
++opened with the
++.B RTLD_GLOBAL
++flag.
++If the executable was linked
++with the flag "-rdynamic", then the global symbols in the executable
++will also be used to resolve references in a dynamically loaded
++library.
++.PP
++.I flag
++must be either
++.BR RTLD_LAZY ,
++meaning resolve undefined symbols as code from the dynamic library is
++executed, or
++.BR RTLD_NOW ,
++meaning resolve all undefined symbols before
++.B dlopen
++returns, and fail if this cannot be done.
++Optionally,
++.B RTLD_GLOBAL
++may be or'ed with
++.IR flag,
++in which case the external symbols defined in the library will be
++made available to subsequently loaded libraries.
++.PP
++If the library exports a routine named
++.BR _init ,
++then that code is executed before dlopen returns.
++If the same library is loaded twice with
++.BR dlopen() ,
++the same file handle is returned. The dl library maintains link
++counts for dynamic file handles, so a dynamic library is not
++deallocated until
++.B dlclose
++has been called on it as many times as
++.B dlopen
++has succeeded on it.
++.PP
++If
++.B dlopen
++fails for any reason, it returns NULL.
++A human readable string describing the most recent error that occurred
++from any of the dl routines (dlopen, dlsym or dlclose) can be
++extracted with
++.BR dlerror() .
++.B dlerror
++returns NULL if no errors have occurred since initialization or since
++it was last called. (Calling
++.B dlerror()
++twice consecutively, will always result in the second call returning
++NULL.)
++
++.B dlsym
++takes a "handle" of a dynamic library returned by dlopen and the null
++terminated symbol name, returning the address where that symbol is
++loaded. If the symbol is not found,
++.B dlsym
++returns NULL; however, the correct way to test for an error from
++.B dlsym
++is to save the result of
++.B dlerror
++into a variable, and then check if saved value is not NULL.
++This is because the value of the symbol could actually be NULL.
++It is also necessary to save the results of
++.B dlerror
++into a variable because if
++.B dlerror
++is called again, it will return NULL.
++.PP
++.B dladdr
++returns information about the shared library containing the memory
++location specified by
++.IR address .
++.B dladdr
++returns zero on success and non-zero on error.
++.PP
++.B dlclose
++decrements the reference count on the dynamic library handle
++.IR handle .
++If the reference count drops to zero and no other loaded libraries use
++symbols in it, then the dynamic library is unloaded. If the dynamic
++library exports a routine named
++.BR _fini ,
++then that routine is called just before the library is unloaded.
++.SH EXAMPLES
++.B Load the math library, and print the cosine of 2.0:
++.RS
++.nf
++.if t .ft CW
++#include <dlfcn.h>
++
++int main(int argc, char **argv) {
++ void *handle = dlopen ("/lib/libm.so", RTLD_LAZY);
++ double (*cosine)(double) = dlsym(handle, "cos");
++ printf ("%f\\n", (*cosine)(2.0));
++ dlclose(handle);
++}
++.if t .ft P
++.fi
++.PP
++If this program were in a file named "foo.c", you would build the program
++with the following command:
++.RS
++.LP
++gcc -rdynamic -o foo foo.c -ldl
++.RE
++.RE
++.LP
++.B Do the same thing, but check for errors at every step:
++.RS
++.nf
++.if t .ft CW
++#include <stdio.h>
++#include <dlfcn.h>
++
++int main(int argc, char **argv) {
++ void *handle;
++ double (*cosine)(double);
++ char *error;
++
++ handle = dlopen ("/lib/libm.so", RTLD_LAZY);
++ if (!handle) {
++ fputs (dlerror(), stderr);
++ exit(1);
++ }
++
++ cosine = dlsym(handle, "cos");
++ if ((error = dlerror()) != NULL) {
++ fputs(error, stderr);
++ exit(1);
++ }
++
++ printf ("%f\\n", (*cosine)(2.0));
++ dlclose(handle);
++}
++.if t .ft P
++.fi

++@unnumbered Introduction
++
++The @code{ld.so} suite contains special files and utilities needed for linux
++to handle @dfn{dynamic libraries}.
++
++Ordinary static libraries (@file{lib*.a} files) are included into executables
++that use their functions. A file that only uses static libraries needs less
++intelligence to load, but takes up more space. If many executables use the
++same library, there can be much wastage of storage space, since multiple
++copies of the library functions are scattered across the executables.
++However, static libraries are easier to make.
++
++Dynamic libraries (@file{lib*.so*} files) are not copied into executables ---
++the executable is written in such a way that it will automatically load the
++libraries. In linux, the executable will first load the special library
++@code{ld.so} or @code{ld-linux.so}, which contains the intelligence
++to load further dynamic libraries. Since multiple files end up getting
++executable data from the same file, dynamic libraries are also known as
++shared libraries.
++
++Linux executables come in two flavors, @sc{elf} and a.out.
++
++a.out is the original executable format used by Linux. It has somewhat less
++overhead than @sc{elf}. However creating shared libraries for a.out is
++@emph{very} involved, and each a.out shared library must be explicitly
++registered.
++
++@sc{elf} is a more recent format, which supports a much simpler method of
++creating libraries. @sc{elf} libraries may also be linked manually
++(@pxref{libdl}).
++
++Since many library authors prefer @sc{elf} and no longer release shared a.out
++libraries, a.out is moribund on Linux. This version of the @code{ld.so} can
++be compiled to support only @sc{elf}, or to support both formats. (The last
++release of ld.so to support a.out alone was 1.8.0.)
++
++@node ld.so
++@chapter @code{ld.so}: Dynamic linker core
++
++@code{ld.so} works behind the scenes to handle dynamic libraries in Linux.
++Users will almost never have to deal with it directly, but in special cases
++one can send instructions to it through environment variables. Also, if
++something is wrong with your libraries (usually an incorrect version) ld.so
++will give error messages.
++
++Actually @code{ld.so} is the a.out linker. The new @sc{elf} executables are
++handled by a related program @code{ld-linux.so}.

++@section Configuration Files
++
++@table @file
++@item /etc/ld.so.cache
++A file created by @code{ldconfig} and used to speed linking. It's structure
++is private to the suite.
++
++@item /etc/ld.so.conf
++A simple list of directories to scan for libraries, in addition to
++@file{/usr/lib} and @file{/lib}, which are hardwired. It may contain
++comments started with a @samp{#}.
++
++@item /etc/ld.so.preload
++A list of libraries to preload. This allows preloading libraries for
++setuid/setgid executables securely. It may contain comments.
++@end table
++
++@node environment
++@section Environment Variables
++
++@table @code
++@item LD_AOUT_LIBRARY_PATH
++@itemx LD_LIBRARY_PATH
++These variables supply a library path for finding dynamic libraries, in the
++standard colon seperated format. These variables are ignored when executing
++setuid/setgid programs, because otherwise they would be a security hazard.
++@code{ld.so} will use @code{LD_AOUT_LIBRARY_PATH} and @code{ld-linux.so} will
++use @code{LD_LIBRARY_PATH}.
++
++@item LD_AOUT_PRELOAD
++@itemx LD_PRELOAD
++These variables allow an extra library not specified in the executable to be
++loaded. Generally this is only useful if you want to override a function.
++These are also ignored when running setuid/setgid executables. @code{ld.so}
++will use @code{LD_AOUT_PRELOAD} and @code{ld-linux.so} will use
++@code{LD_PRELOAD}.
++
++@item LD_NOWARN
++If non-empty, errors about incompatible minor revisions are suppressed.
++
++@item LD_KEEPDIR
++If non-empty, allow executables to specify absolute library names. This
++option is deprecated.
++@c FIXME:
++@c The following are things I noticed in the ld-linux.so source.
++@c I don't really understand 'em. Could someone help me?
++@c
++@c @item LD_BIND_NOW
++@c This option is used by the @code{ld-linux.so} only. I don't know
++@c what it does. (I suspect, looking at the code, that it specifies
++@c "RTLD_NOW" rather than "RTLD_LAZY" mode for the shared libraries.)
++@c
++@c @item LD_TRACE_LOADED_OBJECTS
++@c @itemx LD_WARN
++@c These seem to have something to do with the communication between the
++@c @code{ld-linux.so} and @code{ldd}. I don't know more.
++@end table
++
++@node errors
++@section Errors
++
++@table @samp
++@item Can't find library @var{library}
++The executable required a dynamically linked library that ld.so cannot find.
++Your symbolic links may be not set right, or you may have not installed a
++library needed by the program.
++
++@item Can't load library @var{library}
++The library is corrupt.
++
++@item Incompatible library @var{library}
++@itemx Require major version @var{x} and found @var{y}
++Your version of the library is incompatible with the executable. Recompiling
++the executable, or upgrading the library will fix the problem.
++
++@item using incompatible library @var{library}
++@itemx Desire minor version >= @var{x} and found @var{y}.
++Your version of the library is older than that expected by the executable,
++but not so old that the library interface has radically changed, so the
++linker will attempt to run anyway. There is a chance that it will work, but
++you should upgrade the library or recompile the software. The environment
++variable @code{LD_NOWARN} can be used to supress this message.
++
++@item too many directories in library path
++The linker only supports up to 32 library directories. You have too many.
++
++@item dynamic linker error in @var{blah}
++The linker is having trouble handling a binary - it is probably corrupt.
++
++@item can't map cache file @var{cache-file}
++@itemx cache file @var{cache-file} @var{blah}
++The linker cache file (generally @file{/etc/ld.so.cache}) is corrupt or
++non-existent. These errors can be ignored, and can be prevented by
++regenerating the cache file with @code{ldconfig}.
++@end table
++
++@node ldd
++@chapter @code{ldd}: Dependency scanner
++
++@code{ldd} is a utility that prints out the dynamic libraries that an
++executable is linked to.
++
++Actually @code{ldd} works by signalling ld.so to print the dependencies.
++For a.out executables this is done by starting the executable with
++@code{argc} equal to 0. The linker detects this and prints the dependencies.
++(This can cause problems with @emph{very} old binaries, which would run as
++normal only with an inappropriate @code{argc}.)
++
++For @sc{elf} executables, special environment variables are used to tell the
++linker to print the dependencies.
++
++@code{ldd} has a few options:
++
++@table @samp
++@item -v
++Print the version number of @code{ldd} itself
++
++@item -V
++Print the version number of the dynamic linker
++
++@item -d
++Report missing functions. This is only supported for @sc{elf} executables.
++
++@item -r
++Report missing objects. This is also only available for @sc{elf}
++executables.
++@end table
++
++@node ldconfig
++@chapter @code{ldconfig}: Setup program
++
++This utility is used by the system administrator to automatically set up
++symbolic links needed by the libraries, and also to set up the cache file.
++
++@code{ldconfig} is run after new dynamic libraries are installed, and if the
++cache file or links are damaged. It is also run when upgrading the
++@code{ld.so} suite itself.
++
++The @file{/lib} and @file{/usr/lib} directories, and any listed in the file
++@file{/etc/ld.so.conf} are scanned by default unless @samp{-n} is used.
++Additional directories may be specified on the command line.
++
++It has the following options:
++
++@table @samp
++@item -D
++Enter debug mode. Implies @samp{-N} and @samp{-X}.
++
++@item -v
++Verbose. Print out links created and directories scanned.
++
++@item -n
++Check directories specified on the commandline @emph{only}.
++
++@item -N
++Do not regenerate the cache.
++
++@item -X
++Do not rebuild symbolic links.
++
++@item -l
++Set up symbolic links for only libraries presented on the command line.
++
++@item -p
++Print out the library pathnames in the cache file (@file{/etc/ld.so.cache})
++@end table
++
++@node libdl
++@chapter User dynamic linking library
++
++The @code{ld.so} package includes a small library of functions
++(@code{libdl}) to allow manual dynamic linking. Normally programs are linked
++so that dynamic functions and objects are automagically available. These
++functions allow one to manually load and access a symbol from a library.
++They are only available for @sc{elf} executables.

++* functions:: How to use the functions
++* example:: A sample program
++@end menu
++
++@node using libdl
++@section Overview
++
++To access this library, add the flag @samp{-ldl} to your compile command when
++linking the executable. You also must include the header file
++@code{dlfcn.h}. You may also need the flag @samp{-rdynamic}, which enables
++resolving references in the loaded libraries against your executable.
++
++Generally, you will first use @code{dlopen} to open a library. Then you use
++@code{dlsym} one or more times to access symbols. Finally you use
++@code{dlclose} to close the library.
++
++These facilities are most useful for language interpreters that provide
++access to external libraries. Without @code{libdl}, it would be neccessary
++to link the interpreter executable with any and all external libraries
++needed by the programs it runs. With @code{libdl}, the interpreter only
++needs to be linked with the libraries it uses itself, and can dynamically
++load in additional ones if programs need it.
++
++@node functions
++@section Functions
++
++@deftypefun void *dlopen ( const char @var{filename}, int @var{flags} )
++
++This function opens the dynamic library specified by @var{filename}
++and returns an abstract handle, which can be used in subsequent calls to
++@code{dlsym}. The function will respect the @code{LD_ELF_LIBRARY_PATH} and
++@code{LD_LIBRARY_PATH} environment variables.
++
++@end deftypefun
++
++The following flags can be used with @code{dlopen}:
++
++@deftypevr Macro int RTLD_LAZY
++Resolve symbols in the library as they are needed.
++@end deftypevr
++
++@deftypevr Macro int RTLD_NOW
++Resolve all symbols in the library before returning, and fail if not all can
++be resolved. This is mutually exclusive with @code{RTLD_LAZY}.
++@end deftypevr
++
++@deftypevr Macro int RTLD_GLOBAL
++Make symbols in this library available for resolving symbols in other
++libraries loaded with @code{dlopen}.
++@end deftypevr
++
++@deftypefun int dlclose ( void *@var{handle} )
++
++This function releases a library handle.
++
++Note that if a library opened twice, the handle will be the same. However,
++a reference count is used, so you should still close the library as many
++times as you open it.
++
++@end deftypefun
++
++@deftypefun void *dlsym (void *@var{handle},char *@var{symbol-name})
++
++This function looks up the name @var{symbol-name} in the library and returns
++it in the void pointer.
++
++If there is an error, a null pointer will be returned. However, it is
++possible for a valid name in the library to have a null value, so
++@code{dlerror} should be used to check if there was an error.
++
++@end deftypefun
++
++@deftypefun {libdl function} {const char} *dlerror( void )
++
++This function is used to read the error state. It returns a human-readable
++string describing the last error, or null, meaning no error.
++
++The function resets the error value each time it is called, so the result
++should be copied into a variable. If the function is called more than once
++after an error, the second and subsequent calls will return null.
++
++@end deftypefun
++
++@node example
++@section Example program
++
++Here is an example program that prints the cosine of two by manually linking
++to the math library:
++
++@example
++@c The following was snarfed verbatim from the dlopen.3 man file.
++#include <stdio.h>
++#include <dlfcn.h>
++
++int main(int argc, char **argv) @{
++ void *handle;
++ double (*cosine)(double);
++ char *error;
++
++ handle = dlopen ("/lib/libm.so", RTLD_LAZY);
++ if (!handle) @{
++ fputs (dlerror(), stderr);
++ exit(1);
++ @}
++
++ cosine = dlsym(handle, "cos");
++ if ((error = dlerror()) != NULL) @{
++ fputs(error, stderr);
++ exit(1);
++ @}
++
++ printf ("%f\\n", (*cosine)(2.0));
++ dlclose(handle);
++@}
++@end example

++.SH DESCRIPTION
++.B ldconfig
++creates the necessary links and cache (for use by the run-time linker,
++.IR ld.so )
++to the most recent shared libraries found in the directories specified
++on the command line, in the file
++.IR /etc/ld.so.conf ,
++and in the trusted directories
++.RI ( /usr/lib
++and
++.IR /lib ).
++.B ldconfig
++checks the header and file names of the libraries it encounters when
++determining which versions should have their links updated.
++.B ldconfig
++ignores symbolic links when scanning for libraries.
++.PP
++.B ldconfig
++will attempt to deduce the type of ELF libs (ie. libc5 or libc6/glibc)
++based on what C libs if any the library was linked against, therefore when
++making dynamic libraries, it is wise to explicitly link against libc (use -lc).
++.PP
++Some existing libs do not contain enough information to allow the deduction of
++their type, therefore the
++.IR /etc/ld.so.conf
++file format allows the specification of an expected type. This is
++.B only
++used for those ELF libs which we can not work out. The format
++is like this "dirname=TYPE", where type can be libc4, libc5 or libc6.
++(This syntax also works on the command line). Spaces are
++.B not
++allowed. Also see the
++.B -p
++option.
++.PP
++Directory names containing an
++.B = are no longer legal
++unless they also have an expected type specifier.
++.PP
++.B ldconfig
++should normally be run by the super-user as it may require write

++.B ldd
++does not work very well on libc.so.5 itself.
++.PP
++.B ldd
++does not work on a.out shared libraries.
++.PP
++.B ldd
++does not work with some extremely old a.out programs which were
++built before
++.B ldd
++support was added to the compiler releases.
++If you use
++.B ldd
++on one of these programs, the program will attempt to run with argc = 0 and
++the results will be unpredictable.
