-2009-07-25 Juan Cespedes <cespedes@debian.org>
-
- * New release 0.5.3
- * Created "libltrace.a" and a simple main program that calls it
- * Added support for callbacks to libltrace
- * Got rid of GNU's Autoconf stuff
- * Make it work again in sparc with new kernel headers
-
-2009-05-21 Juan Cespedes <cespedes@debian.org>
-
- * Release version 0.5.2
- * new fork() and clone() approach:
- + used PTRACE_O_TRACE{FORK,VFORK,CLONE} to trace newly created
- processes instead of figuring it out whether a given syscall
- would create another process or not
- That way, new processes are always traced from the very beginning
- * Use PTRACE_O_TRACEEXEC to check if a process has called exec()
-
-2009-05-07 Juan Cespedes <cespedes@debian.org>
-
- * clean-up of structs Process, Breakpoint, Function and Event
-
-2009-04-07 Juan Cespedes <cespedes@debian.org>
-
- * Improved documentation
- * Cleaning up of "struct options"
- * wait_for_something -> sysdeps/linux/events.c:next_event()
- * wait for new children to stop instead of assuming they have stopped
-
-2009-02-11 Juan Cespedes <cespedes@debian.org>
-
- * Fixed bug present since the first version (!) of ltrace,
- which caused many programs to segfault when a signal is received:
- + When a breakpoint is hit, and we need to continue with it, we:
- 1) remove the breakpoint
- 2) order a SINGLESTEP
- 3) when control comes back, set the breakpoint again
- 4) let the process continue
- + The problem came when a signal is received in the middle
- of all this (specifically, between 2) and 3)).
- If this is so, we treat the signal "in the usual way",
- it is, at the end we issue a "CONTINUE" instead of the
- needed SINGLESTEP.
-
-2008-12-10 Juan Cespedes <cespedes@debian.org>
-

-2007-08-31 Juan Cespedes <cespedes@debian.org>
-
- * General: Small fixes (indentation, typos, clean-up of code)
- * ltrace.c: Close output file on exit
- * ltrace.c: use getenv("HOME") instead of getpwuid(geteuid())->pw_dir
- * read_config_file.c, display_args.c: remove "ignore" argtype;
- that's what "void" is for
- * packaging/debian/: misc fixes, sync with version 0.5-2

- * testsuite/ltrace.minor/trace-clone.c: sleep(1) to avoid earlier
- termination of process
- * sysdeps/linux-gnu/trace.c: trace_pid(): reverted Petr's patch
- to wait for child to stop, as it stopped following clone()
- * process_event.c: Disable breakpoints before doing fork() (again!),
- to make children work as expected
-
-2007-05-10 Petr Machata <pmachata@redhat.com>
-
- * Based on work of Supriya Kannery <supriyak@in.ibm.com>

-2007-01-19 Petr Machata <pmachata@redhat.com>
-
- * sysdeps/linux-gnu/trace.c (trace_pid): wait for child to stop,
- as indicated by ptrace documentation.
- * proc.c (open_pid): start the traced child again, it will have
- been stopped after trace_pid. Fixes tracing with -p.
- * breakpoints.c: initialize proc->breakpoints always, don't wait
- untill it might be needed. This renders a check in insert_breakpoint
- superfluous. Fixes a sigsegvs experienced with -L.

-
- * sysdeps/linux-gnu/mipsel/* Added mipsel support

- reinsert breakpoints after the child has been started.
-
-

-To create a distribution (ltrace-<version>.tar.gz):
+Basic Installation
+==================
- ./mkdist
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
-To compile:
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
- ./configure
- make
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
-To build debian/control (to create Debian package):
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+* Version 0.7.2 [2012-12-07 Fri]
+** Bugfixes
+*** (Again) detect VDSO entry in r_debug linkmap with non-empty name
+ This bug caused messages like:
+ | Couldn't determine base address of linux-vdso32.so.1
+ | Couldn't load ELF object linux-vdso32.so.1: No such file or directory
+*** Fix building with libunwind 1.1
+*** Fix prototype lookup for -x symbols from shared libraries
+ Ltrace was unable to find prototypes of static symbols in shared
+ libraries. It changed the symbol name internally to the form
+ name@libfoo.so. Thus mangled, symbols were not found in config
+ files.
+
+* Version 0.7.1 [2012-11-29 Thu]
+** Bugfixes
+*** ltrace.conf.5 is now installed to man5 as it should be
+*** [PowerPC] A header file necessary for building is now shipped
+*** [MIPS] Work around duplicate symbol request bug
+ This fixes the ltrace abort:
+ | ./ltrace: proc.c: 755: breakpoint_for_symbol: Assertion `bp->libsym == ((void *)0)' failed.
+
+*** Detect VDSO entry in r_debug linkmap with non-empty name
+ This bug caused messages like:
+ | Couldn't determine base address of linux-vdso32.so.1
+ | Couldn't load ELF object linux-vdso32.so.1: No such file or directory
+
+*** Temporary files are wiped properly after the test suite has been run
+*** Parsing typedefs with common prefix now works as it should
+ More exactly, if there were typedefs X and XY (in this order), and
+ a reference was made to X, ltrace would match XY instead.
+
+** Cofiguration Files
+*** The following prototypes in ltrace.conf were added or updated
+ __ctype_get_mb_cur_max, __endmntent, __getmntent_r, __setmntent,
+ a64l, abort, abs, addmntent, getmntent_r, hasmntopt, inet_addr,
+ inet_aton, inet_lnaof, inet_makeaddr, inet_netof, inet_network,
+ inet_ntoa, kill, l64a, labs, memcpy, memmove, setlocale,
+ sigaction, sigaddset, sigandset, sigdelset, sigemptyset,
+ sigfillset, sigisemptyset, sigismember, signal, sigorset,
+ sigpending, sigprocmask, sigsuspend.
+
+*** Duplicate typedefs are now guarded against
+*** It's now possible to define recursive structures
+ Please read ltrace.conf(5) man page, chapter "recursive
+ structures", to learn about this new feature.
+
+*** New lens "bitvec" is available
+ This allows displaying various data types as bit vectors. Please
+ read ltrace.conf(5) to learn more.
+
+*** Octal lens renamed to "oct"
+ For reasons of consistency with "hex". "octal" is still valid and
+ will be for forseeable future.
+
+*** The hex lens can now format floating point arguments
+
+* Version 0.7.0 [2012-11-09 Fri]
+** Tracing
+*** Full support for tracing multi-threaded processes
+
+ Ltrace now understands thread groups, and it stops all threads
+ before manipulating breakpoints. The downside is that performance
+ of multi-threaded processes is rather bad, because handling any
+ event implies stopping the whole job. The upside is that
+ individual threads don't get random SIGILL's and SIGSEGV's and
+ events are not missed.
+
+*** Support for tracing inter-library calls
+
+ -e and -x were extended to allow library selectors. See the man
+ page for details.
+
+*** Better support for parameter passing ("fetch backend")
+
+ This version brings more complete support for parameter passing,
+ including passing structures in registers, passing double on i386,
+ and other edge cases that were not handled correctly before. The
+ following architectures now have implementation of fetch backend:
+ i386, x86_64, ppc, ppc64, ia64, s390, s390x, m68k.
+
+*** Awareness of deny_ptrace SELinux boolean
+
+ The deny_ptrace boolean denies all processes from being able to
+ use ptrace to manipulate other processes. Ltrace now understands
+ that this boolean exists, and recommends turning it off, if it is
+ on and ltrace fails to attach to a process.
+
+*** Limited support for tracing returns from tail call functions
+*** -e, -x and -l selectors now allow using globs and regular expressions
+
+ See the man page for details of the selector syntax. This changes
+ the way -x and -l behave with respect to tracing libraries opened
+ by dlopen:
+
+ - In 0.6.0, only those -x symbols that were unmatched in main
+ binary were used to search through symbol table of libraries
+ opened with dlopen. In 0.7.0, -x and -e are applied uniformly
+ to each mapped binary: the main binary, dependent DSO's, and any
+ dlopened libraries.
+
+ - In 0.6.0, -l argument was a filename to open and inspect. In
+ 0.7.0, -l is a glob expression matched against each mapped
+ binary.
+
+*** -g command line option dropped
+
+ This option was introduced in 0.6.0 with the meaning identical to
+ -L, which should be used instead.
+
+*** Test suite can now be run under valgrind
+
+ Use --enable-valgrind to turn this on.
+
+*** [ppc] Support both BSS and secure PLTs for 32-bit processes
+*** [mips] Implement software singlestepping
+*** [mips] Add support for CPIC main programs
+*** Support tracing PIE binaries
+
+** Configuration Files
+
+*** New abstraction: parameter pack
+
+ Parameter packs describe zero or more of actual arguments, whose
+ type can be determined in runtime. The only parameter pack
+ currently implemented is "format" for decoding printf-style format
+ strings.
+
+ In future, it should be relatively straightforward to add more
+ parameter packs for functions like execl, and others.
+
+*** New expression: zero
+
+ When used in array length expressions, it means "this array ends
+ at the first element with zero value". C strings are essentially
+ array(char, zero)*.
+
+*** Lenses: change the way that underlying type is rendered
+
+ Lenses are used similarly to parametrized types, e.g.:
+ | void func(lens(int)); |
+
+**** octal
+
+ "octal", which used to be a separate type, is now lens, which can
+ be used to render any underlying type in base 8. Plain "octal"
+ is still valid and means the same thing as "octal(int)".
+
+**** hex, hide, bool
+
+ Similarly, "hex" lens was introduced to format as base 16.
+ "hide" was introduced to conceal given argument. "bool" lens was
+ added to format objects as either true, or false.
+
+**** enum
+
+ "enum" became lens as well. Because enum already uses
+ parentheses to denote the list of enumeration values, the
+ underlying type is selected by square brackets:
+
+ | void func(enum[short](RED,GREEN,BLUE)); |
+
+**** string
+
+ "string" was also turned to lens. The argument can be either a
+ char*, or pointer to array of char, or array of char. The latter
+ is useful in cases like the following:
+
+ | void func_struct_2(struct(string(array(char, 6)))); |
+
+*** Misspelling of "int" as "itn" temporarily accepted, but deprecated
+
+ Pre-0.7 ltrace shipped a buggy version of ltrace.conf that
+ contained the following prototype:
+
+ | itn acl_valid(addr); |
+
+ To support extant versions of ltrace.conf, that use is now
+ considered valid, and "itn" is a synonym of "int". It is however
+ deprecated, and will produce a warning in future.
+
+*** Using void as top-level function argument now deprecated
+
+ Functions that take no arguments shouldn't pretend to take one
+ parameter of void type. For example the following:
+
+ | int fork(void); |
+
+ ... should be declared like this:
+
+ | int fork(); |
+
+ To support extant versions of ltrace.conf, that use is now
+ considered valid. It is however deprecated, and will produce a
+ warning in future.
+
+*** Using void to hide one argument is now obsolete
+
+ Ltrace needs to know the exact underlying type to decide what the
+ calling convention is. The use of void to mean "hide this
+ argument", such as the following example, is therefore obsolete:
+
+ | void func(void, array(int, arg1)); |
+
+ Instead, rewrite the prototype depending on the exact underlying
+ type:
+
+ | void func(hide(int), array(int, arg1)); |
+ | void func(hide(long), array(int, arg1)); |
+
+ To support extant versions of ltrace.conf, this use is still
+ accepted, and "void" is taken to mean "hide(int)". It is however
+ obsolete, produces a warning, and will be removed in future.
+
+** Documentation
+
+*** New manual page ltrace.conf(5)
+*** README, INSTALL brought up to date
+*** New file CREDITS with a list of contributors
+
+** Bugfixes
+
+*** Fix detaching from a process
+
+ Earlier, a process that ltrace detached from would sometimes die
+ of SIGSEGV, SIGTRAP, or SIGILL. These were caused by ltrace
+ detaching from the process just after that process hit a
+ breakpoint. Program counter would thus be left pointing
+ mid-instruction, or signals would be left pending.
+
+*** Argument to -n is now checked for validity
+*** Fix tracing across exec in a stripped binary
+*** [x86] ORIG_RAX/ORIG_EAX may not contain original syscall number
+
+ In cases where the system call shouldn't be restarted, these are
+ set to -1. In that case assume that the return is from the
+ topmost syscall. This gets rid of some "unexpected breakpoint"
+ messages on x86_64 and i386.
+
+*** [ppc] Fix races in tracing -e events in 64-bit processes
+
+ On ppc, the contents of PLT table change after the first call.
+ Ltrace used to handle this by reinserting the (now overwritten)
+ breakpoint after the function returns. This introduced a window
+ where calls to the same function from the same binary (either a
+ recursive calls, or calls from another thread) weren't traced.
+ This is fixed as of 0.7.0.
+
+ As a side effect, events requested via -e now only hit when a PLT
+ call is made, which is consistent with other architectures.
+
+*** [ppc] Allow stepping over lwarx instruction
+
+** Known bugs
+
+*** [arm] Tracing is not supported at all on ARM
+
+ ltrace might work on older kernels, but no attempt was made to
+ fully support it. Newer kernels don't support PTRACE_SINGLESTEP,
+ which ltrace depends on. Before singlestepping is implemented in
+ software, ARM is considered unsupported.
+
+* Version 0.6.0 [2011-01-06 Thu]
+
+** General Features
+
+*** Use autotools for building
+*** New option -b: disables output of signals received by the tracee
+*** New option -w: print stack trace of events
+
+ Pass --with-libunwind to configure to enable the feature. This
+ requires libunwind.
+
+*** Support tracing of symbols from libraries opened with dlopen
+
+ These symbols are selected by -x.
+
+** Architecture-specific Changes
+
+*** Various fixes for MIPS and PowerPC
+*** Support for ARM Thumb mode
+*** Implement fetching of 5th and further function arguments on s390
+*** Support fork/exec syscalls on 31-bit s390
+*** Support for float and double arguments on x86_64
+*** Fixes for return arguments (after '+') in nested calls on x86_64

+-*-org-*-
+* TODO
+** Automatic prototype discovery:
+*** Use debuginfo if available
+ Alternatively, use debuginfo to generate configure file.
+*** Demangled identifiers contain partial prototypes themselves
+** Automatically update list of syscalls?
+** Update /etc/ltrace.conf
+ In particular, we could use a config directory, where packages
+ would install their ltrace config scripts. The config file could
+ be named after SONAME, and automatically read when corresponding
+ library is mapped.
+** More operating systems (solaris?)
+** Get rid of EVENT_ARCH_SYSCALL and EVENT_ARCH_SYSRET
+** Implement displaced tracing
+ A technique used in GDB (and in uprobes, I believe), whereby the
+ instruction under breakpoint is moved somewhere else, and followed
+ by a jump back to original place. When the breakpoint hits, the IP
+ is moved to the displaced instruction, and the process is
+ continued. We avoid all the fuss with singlestepping and
+ reenablement.
+** Create different ltrace processes to trace different children
+** Config file syntax
+*** named arguments
+ This would be useful for replacing the arg1, emt2 etc.
+
+*** parameter pack improvements
+ The above format tweaks require that packs that expand to no types
+ at all be supported. If this works, then it should be relatively
+ painless to implement conditionals:
+
+ | void ptrace(REQ=enum(PTRACE_TRACEME=0,...),
+ | if[REQ==0](pack(),pack(pid_t, void*, void *)))
+
+ This is of course dangerously close to a programming language, and
+ I think ltrace should be careful to stay as simple as possible.
+ (We can hook into Lua, or TinyScheme, or some such if we want more
+ general scripting capabilities. Implementing something ad-hoc is
+ undesirable.) But the above can be nicely expressed by pattern
+ matching:
+
+ | void ptrace(REQ=enum[int](...)):
+ | [REQ==0] => ()
+ | [REQ==1 or REQ==2] => (pid_t, void*)
+ | [true] => (pid_t, void*, void*);
+
+ Or:
+
+ | int open(string, FLAGS=flags[int](O_RDONLY=00,...,O_CREAT=0100,...)):
+ | [(FLAGS & 0100) != 0] => (flags[int](S_IRWXU,...))
+
+ This would still require pretty complete expression evaluation.
+ _Including_ pointer dereferences and such. And e.g. in accept, we
+ need subtraction:
+
+ | int accept(int, +struct(short, +array(hex(char), X-2))*, (X=uint)*);
+
+ Perhaps we should hook to something after all.
+
+*** errno tracking
+ Some calls result in setting errno. Somehow mark those, and on
+ failure, show errno.
+
+*** second conversions?
+ This definitely calls for some general scripting. The goal is to
+ have seconds in adjtimex calls show as e.g. 10s, 1m15s or some
+ such.
+
+*** format should take arguments like string does
+ Format should take value argument describing the value that should
+ be analyzed. The following overwriting rules would then apply:
+
+ | format | format(array(char, zero)*) |
+ | format(LENS) | X=LENS, format[X] |
+
+ The latter expanded form would be canonical.
+
+ This depends on named arguments and parameter pack improvements
+ (we need to be able to construct parameter packs that expand to
+ nothing).
+
+*** More fine-tuned control of right arguments
+ Combination of named arguments and some extensions could take care
+ of that:
+
+ | void func(X=hide(int*), long*, +pack(X)); |
+
+ This would show long* as input argument (i.e. the function could
+ mangle it), and later show the pre-fetched X. The "pack" syntax is
+ utterly undeveloped as of now. The general idea is to produce
+ arguments that expand to some mix of types and values. But maybe
+ all we need is something like
+
+ | void func(out int*, long*); |
+
+ ltrace would know that out/inout/in arguments are given in the
+ right order, but left pass should display in and inout arguments
+ only, and right pass then out and inout. + would be
+ backward-compatible syntactic sugar, expanded like so:
+
+ | void func(int*, int*, +long*, long*); |
+ | void func(in int*, in int*, out long*, out long*); |
+
+ But sometimes we may want to see a different type on the way in and
+ on the way out. E.g. in asprintf, what's interesting on the way in
+ is the address, but on the way out we want to see buffer contents.
+ Does something like the following make sense?
+
+ | void func(X=void*, long*, out string(X)); |
+
+** Support for functions that never return
+ This would be useful for __cxa_throw, presumably also for longjmp
+ (do we handle that at all?) and perhaps a handful of others.
+
+** Support flag fields
+ enum-like syntax, except disjunction of several values is assumed.
+** Support long long
+ We currently can't define time_t on 32bit machines. That mean we
+ can't describe a range of time-related functions.
+
+** Support signed char, unsigned char, char
+ Also, don't format it as characted by default, string lens can do
+ it. Perhaps introduce byte and ubyte and leave 'char' as alias of
+ one of those with string lens applied by default.
+
+** Support fixed-width types
+ Really we should keep everything as {u,}int{8,16,32,64} internally,
+ and have long, short and others be translated to one of those
+ according to architecture rules. Maybe this could be achieved by a
+ per-arch config file with typedefs such as:
+
+ | typedef ulong = uint8_t |
+
+** Some more functions in vect might be made to take const*
+ Or even marked __attribute__((pure)).
+
+* BUGS
+** After a clone(), syscalls may be seen as sysrets in s390 (see trace.c:syscall_p())

+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+*** The result is that libtool may fail to recognize shared libraries

+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

-; Typedefs
-;
-; To make it easier to specify argument lists, you can use 'typedef'
-; directives to avoid repeating complex parameter descriptors:
-;
-; typedef color = enum(RED=1,BLUE=2,GREEN=3)
-; void draw_line(color,int,int,int,int)
-; void draw_square(color,int,int,int,int)
-;
-; Enumerations
-;
-; The syntax is a parenthesized list of key=value assignments, like so:
-; enum (F_DUPFD=0,F_GETFD=1,F_SETFD=2)
-; an example usage might look like
-; int fcntl(int,enum (F_DUPFD=0,F_GETFD=1,F_SETFD=2))
-;
-; Arrays
-;
-; NOTE: Uses of array(...) alone are very rare. You almost always
-; want array(...)*. The exceptions are when you have a fixed-size
-; array.
-;
-; Structs
-;
-; NOTE: Uses of struct(...) alone are very rare. You almost always
-; want struct(...)* (a pointer to a struct) anyway. Most compilers
-; pass structs as pointers anyway, and those that don't are not yet
-; supported. The one time when you want to use a non-pointer
-; struct(...) type are when you have an array of structs, or a struct
-; containing another struct.
-;
-; For example, if you have
-; struct s1 {
-; int y_size;
-; int * y;
-; int z[3];
-; struct { char c; } a;
-; struct { char c; } * b;
-; }
-; and a function
-; void f(struct s1*)
-; then the corresponding ltrace spec is
-; void f(struct(int,array(int,elt0),array(int,3),struct(char),struct(char)*)*)
-; which, formatted similarly to the C declaration, looks like
-; void f(struct(
-; int,
-; array(int,elt0),
-; array(int,3),
-; struct(char),
-; struct(char)*
-; )*
-; )
-

.SH DESCRIPTION
.B ltrace
.SH OPTIONS
.TP
.I \-a, \-\-align column
-Align return values in a specific column (default column is 5/8 of screen width).
+Align return values in a specific
+.IR column
+(default column is 5/8 of screen width).
.TP
.I \-A maxelts
-Maximum number of array elements to print before suppressing the rest with an ellipsis ("...")
+Maximum number of array elements to print before suppressing the rest
+with an ellipsis ("..."). This also limits number of recursive
+structure expansions.
+.TP
+.I \-b, \-\-no-signals
+Disable printing of signals recieved by the traced process.
.TP
.I \-c
Count time and calls for each library call and report a summary on program exit.
DEBUG_FUNCTION. Shows every entry to internal functions
.RE
.TP
-.I \-e expr
-A qualifying expression which modifies which events to trace.
-The format of the expression is:
-.br
-[!]value1[,value2]...
-.br
-where the values are the functions to trace. Using an exclamation
-mark negates the set of values. For example
-.I \-e printf
-means to trace only the printf library call. By contrast,
-.I \-e !printf
-means to trace every library call except printf.
-.IP
-Note that some shells use the exclamation point for history
-expansion; even inside quoted arguments. If so, you must escape
-the exclamation point with a backslash.
+.I \-e filter
+A qualifying expression which modifies which library calls to trace.
+The format of the filter expression is described in the section
+\fBFILTER EXPRESSIONS\fR. If more than one \-e option appears on the
+command line, the library calls that match any of them are traced. If
+no \-e is given, \fB@MAIN\fR is assumed as a default.
.TP
.I \-f
Trace child processes as they are created by
.I \-i
Print the instruction pointer at the time of the library call.
.TP
-.I \-l, \-\-library filename
-Display only the symbols included in the library
-.I filename.
-Up to 30 library names can be specified with several instances
-of this option.
+.I \-l, \-\-library library_pattern
+Display only calls to functions implemented by libraries that match
+.I library_pattern.
+Multiple library patters can be specified with several instances of
+this option. Syntax of library_pattern is described in section
+\fBFILTER EXPRESSIONS\fR.
+
+Note that while this option selects calls that might be directed to
+the selected libraries, there's no actual guarantee that the call
+won't be directed elsewhere due to e.g. LD_PRELOAD or simply
+dependency ordering. If you want to make sure that symbols in given
+library are actually called, use \fB-x @\fIlibrary_pattern\fR instead.
.TP
.I \-L
-DON'T display library calls (use it with the
-.I \-S
-option).
+When no -e option is given, don't assume the default action of
+\fB@MAIN\fR.
.TP
.I \-n, \-\-indent nr
Indent trace output by
This option is only useful when running as root and enables the
correct execution of setuid and/or setgid binaries.
.TP
-.I \-X extern
-Some architectures need to know where to set a breakpoint that will be hit
-after the dynamic linker has run. If this flag is used, then the breakpoint
-is set at
-.IR extern ,
-which must be an external function. By default, '_start' is used.
-NOTE: this flag is only available on the architectures that need it.
+.I \-w, --where NR
+Show backtrace of NR stack frames for each traced function. This option enabled
+only if libunwind support was enabled at compile time.
.TP
-.I \-x extern
-Trace the external function
-.IR extern .
-This option may be repeated.
+.I \-x filter
+A qualifying expression which modifies which symbol table entry points
+to trace. The format of the filter expression is described in the
+section \fBFILTER EXPRESSIONS\fR. If more than one \-x option appears
+on the command line, the symbols that match any of them are traced.
+No entry points are traced if no \-x is given.
.TP
.I \-V, \-\-version
Show the version number of ltrace and exit.
+.SH FILTER EXPRESSIONS
+
+Filter expression is a chain of glob- or regexp-based rules that are
+used to pick symbols for tracing from libraries that the process uses.
+Most of it is intuitive, so as an example, the following would trace
+calls to malloc and free, except those done by libc:
+
+-e malloc+free-@libc.so*
+
+This reads: trace malloc and free, but don't trace anything that comes
+from libc. Semi-formally, the syntax of the above example looks
+approximately like this:
+
+{[+-][\fIsymbol_pattern\fR][@\fIlibrary_pattern\fR]}
+
+\fISymbol_pattern\fR is used to match symbol names,
+\fIlibrary_pattern\fR to match library SONAMEs. Both are implicitly
+globs, but can be regular expressions as well (see below). The glob
+syntax supports meta-characters \fB*\fR and \fB?\fR and character
+classes, similarly to what basic bash globs support. \fB^\fR and
+\fB$\fR are recognized to mean, respectively, start and end of given
+name.
+
+Both \fIsymbol_pattern\fR and \fIlibrary_pattern\fR have to match the
+whole name. If you want to match only part of the name, surround it
+with one or two *'s as appropriate. The exception is if the pattern
+is not mentioned at all, in which case it's as if the corresponding
+pattern were \fB*\fR. (So \fBmalloc\fR is really \fBmalloc@*\fR and
+\fB@libc.*\fR is really \fB*@libc.*\fR.)
+
+In libraries that don't have an explicit SONAME, basename is taken for
+SONAME. That holds for main binary as well: \fB/bin/echo\fR has an
+implicit SONAME of \fBecho\fR. In addition to that, special library
+pattern \fBMAIN\fR always matches symbols in the main binary and never
+a library with actual SONAME \fBMAIN\fR (use e.g. \fB^MAIN\fR or
+\fB[M]AIN\fR for that).
+
+If the symbol or library pattern is surrounded in slashes (/like
+this/), then it is considered a regular expression instead. As a
+shorthand, instead of writing \fB/x/@/y/\fR, you can write
+\fB/x@y/\fR.
+
+If the library pattern starts with a slash, it is not a SONAME
+expression, but a path expression, and is matched against the library
+path name.
+
+The first rule may lack a sign, in which case \fB+\fR is assumed. If,
+on the other hand, the first rule has a \fB-\fR sign, it is as if
+there was another rule \fB@*\fR in front of it.
+
+The above rules are used to construct the set of traced symbols. Each
+candidate symbol is passed through the chain of above rules.
+Initially, the symbol is \fIunmarked\fR. If it matches a \fB+\fR
+rule, it becomes \fImarked\fR, if it matches a \fB-\fR rule, it
+becomes \fIunmarked\fR again. If, after applying all rules, the
+symbol is \fImarked\fR, it will be traced.
+

+.TH ltrace.conf "5" "October 2012" "" "ltrace configuration file"
+.SH "NAME"
+.LP
+\fBltrace.conf\fR \- Configuration file for \fBltrace(1)\fR.
+
+.SH DESCRIPTION
+
+This manual page describes \fBltrace.conf\fR, a file that describes
+prototypes of functions in binaries for \fBltrace(1)\fR to use.
+Ltrace needs this information to display function call arguments.
+
+Each line of a configuration file describes at most a single item.
+Lines composed entirely of white space are ignored, as are lines
+starting with semicolon character (comment lines). Described items
+can be either function prototypes, or definitions of type aliases.
+
+.SH PROTOTYPES
+
+A prototype describes return type and parameter types of a single
+function. The syntax is as follows:
+
+.RS
+\fILENS\fR \fINAME\fR \fB(\fR[\fILENS\fR{,\fILENS\fR}]\fB);\fR
+.RE
+
+\fINAME\fR is the (mangled) name of a symbol. In the elementary case,
+\fILENS\fR is simply a type. Both lenses and types are described
+below. For example, a simple function prototype might look like this:
+
+.RS
+.B int\fR kill\fB(int,int);
+.RE
+
+Despite the apparent similarity with C, \fBltrace.conf\fR is really
+its own language that's only somewhat inspired by C.
+
+.SH TYPES
+
+Ltrace understands a range of primitive types. Those are interpreted
+according to C convention native on a given architecture.
+E.g. \fBulong\fR is interpreted as 4-byte unsigned integer on 32-bit
+GNU/Linux machine, but 8-byte unsigned integer on 64-bit GNU/Linux
+machine.
+
+.TP
+.B void
+Denotes that a function does not return anything. Can be also used to
+construct a generic pointer, i.e. pointer-sized number formatted in
+hexadecimal format.
+.TP
+.B char
+8-bit quantity rendered as a character
+.TP
+.B ushort,short
+Denotes unsigned or signed short integer.
+.TP
+.B uint,int
+Denotes unsigned or signed integer.
+.TP
+.B ulong,long
+Denotes unsigned or signed long integer.
+.TP
+.B float
+Denotes floating point number with single precision.
+.TP
+.B double
+Denotes floating point number with double precision.
+.PP
+
+Besides primitive types, the following composed types are possible:
+
+.TP
+.B struct(\fR[\fILENS\fR{,\fILENS\fR}]\fB)\fR
+Describes a structure with given types as fields,
+e.g. \fBstruct(int,int,float)\fR.
+
+Alignment is computed as customary on the architecture. Custom
+alignment (e.g. packed structs) and bit-fields are not supported.
+It's also not possible to differentiate between structs and non-POD
+C++ classes, for arches where it makes a difference.
+
+.TP
+.B array(\fR\fILENS\fR\fB,\fIEXPR\fR\fB)
+Describes array of length \fIEXPR\fR, which is composed of types
+described by \fILENS\fR, e.g. \fBarray(int, \fR6\fB)\fR.
+
+Note that in C, arrays in role of function argument decay into
+pointers. Ltrace currently handles this automatically, but for full
+formal correctness, any such arguments should be described as pointers
+to arrays.
+
+.TP
+.I LENS\fR\fB*
+Describes a pointer to a given type, e.g. \fBchar*\fR or \fBint***\fR.
+Note that the former example actually describes a pointer to a
+character, not a string. See below for \fBstring\fR lens, which is
+applicable to these cases.
+
+.SH LENSES
+
+Lenses change the way that types are described. In the simplest case,
+a lens is directly a type. Otherwise a type is decorated by the lens.
+Ltrace understands the following lenses:
+
+.TP
+.B oct(\fITYPE\fB)
+The argument, which should be an integer type, is formatted in base-8.
+
+.TP
+.B hex(\fITYPE\fB)
+The argument, which should be an integer or floating point type, is
+formatted in base-16. Floating point arguments are converted to
+double and then displayed using the \fB%a\fR fprintf modifier.
+
+.TP
+.B hide(\fITYPE\fB)
+The argument is not shown in argument list.
+
+.TP
+.B bool(\fITYPE\fB)
+Arguments with zero value are shown as "false", others are shown as
+"true".
+
+.TP
+.B bitvec(\fITYPE\fB)
+Underlying argument is interpreted as a bit vector and a summary of
+bits set in the vector is displayed. For example if bits 3,4,5 and 7
+of the bit vector are set, ltrace shows <3-5,7>. Empty bit vector is
+displayed as <>. If there are more bits set than unset, inverse is
+shown instead: e.g. ~<0> when a number 0xfffffffe is displayed. Full
+set is thus displayed ~<>.
+
+If the underlying type is integral, then bits are shown in their
+natural big-endian order, with LSB being bit 0.
+E.g. \fBbitvec(ushort)\fR with value 0x0102 would be displayed as
+<1,8>, irrespective of underlying byte order.
+
+For other data types (notably structures and arrays), the underlying
+data is interpreted byte after byte. Bit 0 of first byte has number
+0, bit 0 of second byte number 8, and so on. Thus
+\fBbitvec(struct(int))\fR is endian sensitive, and will show bytes
+comprising the integer in their memory order. Pointers are first
+dereferenced, thus \fBbitvec(array(char, \fR32\fB)*)\fR is actually a
+pointer to 256-bit bit vector.
+
+.PP
+.B string(\fITYPE\fB)
+.br
+.B string[\fIEXPR\fB]
+.br
+.B string
+.RS
+The first form of the argument is canonical, the latter two are
+syntactic sugar. In the canonical form, the function argument is
+formatted as string. The \fITYPE\fR shall be either a \fBchar*\fR, or
+\fBarray(char,\fIEXPR\fB)\fR, or \fBarray(char,\fIEXPR\fB)*\fR. If an
+array is given, the length will typically be a \fBzero\fR expression
+(but doesn't have to be). Using argument that is plain array
+(i.e. not a pointer to array) makes sense e.g. in C structs, in cases
+like \fBstruct(string(array(char, \fR6\fB)))\fR, which describes the C
+type \fBstruct {char \fRs\fB[\fR6\fB];}\fR.
+
+Because simple C-like strings are pretty common, there are two
+shorthand forms. The first shorthand form (with brackets) means the
+same as \fBstring(array(char, \fIEXPR\fB)*)\fR. Plain \fBstring\fR
+without an argument is then taken to mean the same as
+\fBstring[zero]\fR.
+
+Note that \fBchar*\fR by itself describes a pointer to a char. Ltrace
+will dereference the pointer, and read and display the single
+character that it points to.
+.RE
+
+.B enum(\fINAME\fR[\fB=\fIVALUE\fR]{,\fINAME\fR[\fB=\fIVALUE\fR]}\fB)
+.br
+.B enum[\fITYPE\fB]\fB(\fINAME\fR[\fB=\fIVALUE\fR]{,\fINAME\fR[\fB=\fIVALUE\fR]}\fB)
+.RS
+This describes an enumeration lens. If an argument has any of the
+given values, it is instead shown as the corresponding \fINAME\fR. If
+a \fIVALUE\fR is omitted, the next consecutive value following after
+the previous \fIVALUE\fR is taken instead. If the first \fIVALUE\fR
+is omitted, it's \fB0\fR by default.
+
+\fITYPE\fR, if given, is the underlying type. It is thus possible to
+create enums over shorts or longs\(emarguments that are themselves
+plain, non-enum types in C, but whose values can be meaningfully
+described as enumerations. If omitted, \fITYPE\fR is taken to be
+\fBint\fR.
+.RE
+
+.SH TYPE ALIASES
+
+A line in config file can, instead of describing a prototype, create a
+type alias. Instead of writing the same enum or struct on many places
+(and possibly updating when it changes), one can introduce a name for
+such type, and later just use that name:
+
+.RS
+\fBtypedef \fINAME\fB = \fILENS\fB;\fR
+.RE
+
+.SH RECURSIVE STRUCTURES
+
+Ltrace allows you to express recursive structures. Such structures
+are expanded to the depth described by the parameter -A. To declare a
+recursive type, you first have to introduce the type to ltrace by
+using forward declaration. Then you can use the type in other type
+definitions in the usual way:
+
+.RS
+.B typedef \fINAME\fB = struct;
+.br
+.B typedef \fINAME\fB = struct(\fINAME\fR can be used here\fB)
+.RE
+
+For example, consider the following singy-linked structure and a
+function that takes such list as an argument:
+
+.RS
+.B typedef\fR int_list \fB= struct;
+.br
+.B typedef\fR int_list \fB= struct(int,\fR int_list\fB*);
+.br
+.B void\fR ll\fB(\fRint_list\fB*);
+.RE
+
+Such declarations might lead to an output like the following:
+
+.RS
+ll({ 9, { 8, { 7, { 6, ... } } } }) = <void>
+.RE
+
+Ltrace detects recursion and will not expand already-expanded
+structures. Thus a doubly-linked list would look like the following:
+
+.RS
+.B typedef\fR int_list \fB= struct;
+.br
+.B typedef\fR int_list \fB= struct(int,\fR int_list\fB*,\fR int_list\fB*);
+.RE
+
+With output e.g. like:
+
+.RS
+ll({ 9, { 8, { 7, { 6, ..., ... }, recurse^ }, recurse^ }, nil })
+.RE
+
+The "recurse^" tokens mean that given pointer points to a structure
+that was expanded in the previous layer. Simple "recurse" would mean
+that it points back to this object. E.g. "recurse^^^" means it points
+to a structure three layers up. For doubly-linked list, the pointer
+to the previous element is of course the one that has been just
+expanded in the previous round, and therefore all of them are either
+recurse^, or nil. If the next and previous pointers are swapped, the
+output adjusts correspondingly:
+
+.RS
+ll({ 9, nil, { 8, recurse^, { 7, recurse^, { 6, ..., ... } } } })
+.RE
+
+
+.SH EXPRESSIONS
+
+Ltrace has support for some elementary expressions. Each expression
+can be either of the following:
+
+.TP
+.I NUM
+An integer number.
+
+.TP
+.B arg\fINUM
+Value of \fINUM\fR-th argument. The expression has the same value as
+the corresponding argument. \fBarg1\fR refers to the first argument,
+\fBarg0\fR to the return value of the given function.
+
+.TP
+.B retval
+Return value of function, same as \fBarg0\fR.
+
+.TP
+.B elt\fINUM
+Value of \fINUM\fR-th element of the surrounding structure type. E.g.
+\fBstruct(ulong,array(int,elt1))\fR describes a structure whose first
+element is a length, and second element an array of ints of that
+length.
+
+.PP
+.B zero
+.br
+.B zero(\fIEXPR\fB)
+.RS
+Describes array which extends until the first element, whose each byte
+is 0. If an expression is given, that is the maximum length of the
+array. If NUL terminator is not found earlier, that's where the array
+ends.
+.RE
+
+.SH PARAMETER PACKS
+
+Sometimes the actual function prototype varies slightly depending on
+the exact parameters given. For example, the number and types of
+printf parameters are not known in advance, but ltrace might be able
+to determine them in runtime. This feature has wider applicability,
+but currently the only parameter pack that ltrace supports is
+printf-style format string itself:
+
+.TP
+.B format
+When \fBformat\fR is seen in the parameter list, the underlying string
+argument is parsed, and GNU-style format specifiers are used to
+determine what the following actual arguments are. E.g. if the format
+string is "%s %d\\n", it's as if the \fBformat\fR was replaced by
+\fBstring, string, int\fR.
+
+.SH RETURN ARGUMENTS
+
+C functions often use one or more arguments for returning values back
+to the caller. The caller provides a pointer to storage, which the
+called function initializes. Ltrace has some support for this idiom.
+
+When a traced binary hits a function call, ltrace first fetches all
+arguments. It then displays \fIleft\fR portion of the argument list.
+Only when the function returns does ltrace display \fIright\fR portion
+as well. Typically, left portion takes up all the arguments, and
+right portion only contains return value. But ltrace allows you to
+configure where exactly to put the dividing line by means of a \fB+\fR
+operator placed in front of an argument:
+
+.RS
+.B int\fR asprintf\fB(+string*, format);
+.RE
+
+Here, the first argument to asprintf is denoted as return argument,
+which means that displaying the whole argument list is delayed until
+the function returns:
+
+.RS
+a.out->asprintf( <unfinished ...>
+.br
+libc.so.6->malloc(100) = 0x245b010
+.br
+[... more calls here ...]
+.br
+<... asprintf resumed> "X=1", "X=%d", 1) = 5
+.RE
+
+It is currently not possible to have an "inout" argument that passes
+information in both directions.
+
+.SH EXAMPLES
+
+In the following, the first is the C prototype, and following that is
+ltrace configuration line.
+

+.B void\fR func_charp_string\fB(char\fR str\fB[]);
+.B void\fR func_charp_string\fB(string);

+/* There are two PLT types on 32-bit PPC: old-style, BSS PLT, and
+ * new-style "secure" PLT. We can tell one from the other by the
+ * flags on the .plt section. If it's +X (executable), it's BSS PLT,
+ * otherwise it's secure.
+ *
+ * BSS PLT works the same way as most architectures: the .plt section
+ * contains trampolines and we put breakpoints to those. If not
+ * prelinked, .plt contains zeroes, and dynamic linker fills in the
+ * initial set of trampolines, which means that we need to delay
+ * enabling breakpoints until after binary entry point is hit.
+ * Additionally, after first call, dynamic linker updates .plt with
+ * branch to resolved address. That means that on first hit, we must
+ * do something similar to the PPC64 gambit described below.
+ *
+ * With secure PLT, the .plt section doesn't contain instructions but
+ * addresses. The real PLT table is stored in .text. Addresses of
+ * those PLT entries can be computed, and apart from the fact that
+ * they are in .text, they are ordinary PLT entries.
+ *
+ * 64-bit PPC is more involved. Program linker creates for each
+ * library call a _stub_ symbol named xxxxxxxx.plt_call.<callee>
+ * (where xxxxxxxx is a hexadecimal number). That stub does the call
+ * dispatch: it loads an address of a function to call from the
+ * section .plt, and branches. PLT entries themselves are essentially
+ * a curried call to the resolver. When the symbol is resolved, the
+ * resolver updates the value stored in .plt, and the next time
+ * around, the stub calls the library function directly. So we make
+ * at most one trip (none if the binary is prelinked) through each PLT
+ * entry, and correspondingly that is useless as a breakpoint site.
+ *
+ * Note the three confusing terms: stubs (that play the role of PLT
+ * entries), PLT entries, .plt section.
+ *
+ * We first check symbol tables and see if we happen to have stub
+ * symbols available. If yes we just put breakpoints to those, and
+ * treat them as usual breakpoints. The only tricky part is realizing
+ * that there can be more than one breakpoint per symbol.
+ *
+ * The case that we don't have the stub symbols available is harder.
+ * The following scheme uses two kinds of PLT breakpoints: unresolved
+ * and resolved (to some address). When the process starts (or when
+ * we attach), we distribute unresolved PLT breakpoints to the PLT
+ * entries (not stubs). Then we look in .plt, and for each entry
+ * whose value is different than the corresponding PLT entry address,
+ * we assume it was already resolved, and convert the breakpoint to
+ * resolved. We also rewrite the resolved value in .plt back to the
+ * PLT address.
+ *
+ * When a PLT entry hits a resolved breakpoint (which happens because
+ * we rewrite .plt with the original unresolved addresses), we move
+ * the instruction pointer to the corresponding address and continue
+ * the process as if nothing happened.
+ *
+ * When unresolved PLT entry is called for the first time, we need to
+ * catch the new value that the resolver will write to a .plt slot.
+ * We also need to prevent another thread from racing through and
+ * taking the branch without ltrace noticing. So when unresolved PLT
+ * entry hits, we have to stop all threads. We then single-step
+ * through the resolver, until the .plt slot changes. When it does,
+ * we treat it the same way as above: convert the PLT breakpoint to
+ * resolved, and rewrite the .plt value back to PLT address. We then
+ * start all threads again.
+ *
+ * As an optimization, we remember the address where the address was
+ * resolved, and put a breakpoint there. The next time around (when
+ * the next PLT entry is to be resolved), instead of single-stepping
+ * through half the dynamic linker, we just let the thread run and hit
+ * this breakpoint. When it hits, we know the PLT entry was resolved.
+ *
+ * XXX TODO If we have hardware watch point, we might put a read watch
+ * on .plt slot, and discover the offenders this way. I don't know
+ * the details, but I assume at most a handful (like, one or two, if
+ * available at all) addresses may be watched at a time, and thus this
+ * would be used as an amendment of the above rather than full-on
+ * solution to PLT tracing on PPC.
