+*********************************************************************
+
+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.
+
+######################################################################
+
+Changes in version 1.9.11:
+
+ Fixed a bug in ld-linux.so where a reference to an
+ 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)
+
+Changes in version 1.9.5:
+

+ 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
+ library is for even if it doesn't have an soname.
+
+ 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.
+
+ Changed ld-linux.so to load the libraries listed in
+ 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

+ 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:
+

+Changes in version 1.8.3:
+
+ Changed ld-linux.so to process LD_PRELOAD before

+ skipping a library because the soname doesn't match.
+
+ More sparc fixes (Miguel de Icaza).

+ 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).

+
+ 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

+
+ 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.

+
+/*
+ * 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.

+.SH NAME
+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
+.BI "int dladdr(void *"address ", Dl_info *"dlip ");"
+.br
+.BI "int dlclose (void *"handle ");
+.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

+.SH NAME
+ld.so/ld-linux.so \- dynamic linker/loader
+.SH DESCRIPTION
+.B ld.so
+loads the shared libraries needed by a program, prepares the program
+to run, and then runs it.
+Unless explicitly specified via the
+.B \-static
+option to
+.B ld
+during compilation, all Linux programs are incomplete and require
+further linking at run time.
+.PP
+The necessary shared libraries needed by the program are searched for
+in the following order
+.IP o
+Using the environment variable
+.B LD_LIBRARY_PATH
+.RB ( LD_AOUT_LIBRARY_PATH
+for a.out programs).
+Except if the executable is a setuid/setgid binary, in which case it
+is ignored.
+.IP o
+From the cache file
+.BR /etc/ld.so.cache
+which contains a compiled list of candidate libraries previously found
+in the augmented library path.
+.IP o
+In the default path
+.BR /usr/lib ,
+and then
+.BR /lib .
+.SH ENVIRONMENT
+.TP
+.B LD_LIBRARY_PATH
+A colon-separated list of directories in which to search for
+ELF libraries at execution-time.
+Similar to the
+.B PATH
+environment variable.
+.TP
+.B LD_PRELOAD
+A whitespace-separated list of additional, user-specified, ELF shared
+libraries to be loaded before all others.

+@node intro
+@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}.

+@end menu
+
+@node files
+@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);
+@}

+.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
