-*-org-*-
+* Version 0.8.0
+** Prototype libraries
+ - Each DSO can now ship an ltrace config file (called prototype
+ library) that ltrace will open when that DSO is loaded to process
+ image. See ltrace(1) for details.
+
+ - ltrace.conf is no longer part of installation tarball. Instead,
+ we now ship libc.so.conf, libm.so.conf, libacl.so.conf, and
+ syscalls.conf. Those are now istalled to /usr/share/ltrace by
+ default. /etc/ltrace.conf and $HOME/.ltrace.conf are still
+ loaded if present, and can contain arbitrary user configuration.
+
+ - The option -F was retrofitted to be a colon-separated list of
+ prototype libraries, and directories to look for prototype
+ libraries in. On Linux, ltrace looks into XDG_CONFIG_HOME,
+ XDG_CONFIG_DIRS, and /usr/share/ltrace as well.
+
+** Architectural support
+ - MIPS and MIPSel are now handled by the same backend.
+ - ARMv6 and ARMv7 are supported, including full fetch backend.
+ - Imagination Technologies Meta is now supported.
+ - On Linux, tracing of IFUNC symbols is supported. On i386 and
+ x86_64, IRELATIVE PLT slots are traced as well.
+
+** -w output now shows full library path
+ The output format is similar to glibc's backtrace_symbols, e.g.:
+ > /bin/ls(_init+0x19be) [0x40398e]
+ > /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xed) [0x7f50cbc3676d]
+ > /bin/ls(_init+0x25fd) [0x4045cd]
+
+* Version 0.7.3 [2013-09-15 Sun]
+** Bugfixes
+*** [MIPS] Fix build on mips big endian
+ This bug caused messages like:
+ | Making all in mips
+ | /bin/sh: line 17: cd: mips: No such file or directory
+*** [MIPS] Fix SIGSEGV on mips big endian
+ This bug caused runtime messages like:
+ | [0x4000000] --- SIGSEGV (Segmentation fault) ---
+ | [0xffffffff] +++ killed by SIGSEGV +++
+*** Fix build with CLANG on FREEBSD
+
* Version 0.7.2 [2012-12-07 Fri]

** Automatic prototype discovery:
*** Use debuginfo if available
Alternatively, use debuginfo to generate configure file.
-*** Demangled identifiers contain partial prototypes themselves
+*** Mangled identifiers contain partial prototypes themselves
+ They don't contain return type info, which can change the
+ parameter passing convention. We could use it and hope for the
+ best.
** 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
reenablement.
** Create different ltrace processes to trace different children
** Config file syntax
+*** mark some symbols as exported
+ For PLT hits, only exported prototypes would be considered. For
+ symtab entry point hits, all would be.
+
*** named arguments
This would be useful for replacing the arg1, emt2 etc.
Perhaps we should hook to something after all.
+*** system call error returns
+
+ This is closely related to above. Take the following syscall
+ prototype:
+
+ | long read(int,+string0,ulong);
+
+ string0 means the same as string(array(char, zero(retval))*). But
+ if read returns a negative value, that signifies errno. But zero
+ takes this at face value and is suspicious:
+
+ | read@SYS(3 <no return ...>
+ | error: maximum array length seems negative
+ | , "\n\003\224\003\n", 4096) = -11
+
+ Ideally we would do what strace does, e.g.:
+
+ | read@SYS(3, 0x12345678, 4096) = -EAGAIN
+
*** errno tracking
Some calls result in setting errno. Somehow mark those, and on
- failure, show errno.
+ failure, show errno. System calls return errno as a negative
+ value (see the previous point).
*** second conversions?
This definitely calls for some general scripting. The goal is to
according to architecture rules. Maybe this could be achieved by a
per-arch config file with typedefs such as:
- | typedef ulong = uint8_t |
+ | typedef ulong = uint8_t; |
+
+** Support for ARM/AARCH64 types
+ - ARM and AARCH64 both support half-precision floating point
+ - there are two different half-precision formats, IEEE 754-2008
+ and "alternative". Both have 10 bits of mantissa and 5 bits of
+ exponent, and differ only in how exponent==0x1F is handled. In
+ IEEE format, we get NaN's and infinities; in alternative
+ format, this encodes normalized value -1S × 2¹⁶ × (1.mant)
+ - The Floating-Point Control Register, FPCR, controls: — The
+ half-precision format where applicable, FPCR.AHP bit.
+ - AARCH64 supports fixed-point interpretation of {,double}words
+ - e.g. fixed(int, X) (int interpreted as a decimal number with X
+ binary digits of fraction).
+ - AARCH64 supports 128-bit quad words in SIMD
** Some more functions in vect might be made to take const*
Or even marked __attribute__((pure)).
+** pretty printer support
+ GDB supports python pretty printers. We migh want to hook this in
+ and use it to format certain types.
+
* BUGS
** After a clone(), syscalls may be seen as sysrets in s390 (see trace.c:syscall_p())

-# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
-# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
-# `$srcdir', `$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.
-#
-# Another solution, used here, is to always expand $ac_aux_dir to an
-# absolute PATH. The drawback is that using absolute paths prevent a

-# 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.

-\`configure' configures ltrace 0.7.2 to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking ...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
- --disable-dependency-tracking speeds up one-time build
- --enable-dependency-tracking do not reject slow dependency extractors
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
- --enable-debug enable debugging [default=no]
- --disable-werror disable use of -Werror
- --enable-valgrind run all tests under valgrind
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-pic try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
- --with-sysroot=DIR Search for dependent libraries within DIR
- (or the compiler's sysroot if not specified).
- --with-libelf Prefix of libelf headers/library
- --with-libunwind Use libunwind frame unwinding support
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to <ltrace-devel@lists.alioth.debian.org>.

.SH DESCRIPTION
.B ltrace
Its use is very similar to
.BR strace(1) .
+.B ltrace
+shows parameters of invoked functions and system calls. To determine
+what arguments each function has, it needs external declaration of
+function prototypes. Those are stored in files called \fIprototype
+libraries\fR--see ltrace.conf(5) for details on the syntax of these
+files. See the section \fBPROTOTYPE LIBRARY DISCOVERY\fR to learn how
+\fBltrace\fR finds prototype libraries.
+
.SH OPTIONS
-.TP
-.I \-a, \-\-align column
+.PP
+.IP "\-a, \-\-align \fIcolumn"
Align return values in a specific
.IR column
(default column is 5/8 of screen width).
-.TP
-.I \-A maxelts
+.IP "\-A \fImaxelts"
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
+.IP "\-b, \-\-no-signals"
Disable printing of signals recieved by the traced process.
-.TP
-.I \-c

+.IP \-c
+Count time and calls for each library call and report a summary on
+program exit.
+.IP "\-C, \-\-demangle"
Decode (demangle) low-level symbol names into user-level names.
Besides removing any initial underscore prefix used by the system,
this makes C++ function names readable.
-.TP
-.I \-D, \-\-debug level
-Show debugging output of
-.B ltrace
-itself.
-.I level
-must be a sum of some of the following numbers:
-.RS
-.TP
-.B 01
-DEBUG_GENERAL. Shows helpful progress information
-.TP
-.B 010
-DEBUG_EVENT. Shows every event received by a traced program
-.TP
-.B 020
-DEBUG_PROCESS. Shows every action
-.B ltrace
-carries upon a traced process
-.TP
-.B 040
-DEBUG_FUNCTION. Shows every entry to internal functions
-.RE
-.TP
-.I \-e filter
+.IP "\-D, \-\-debug \fRmask\fI"
+Show debugging output of \fBltrace\fR itself. \fImask\fR is a number
+with internal meaning that's not really well defined at all.
+\fImask\fR of 77 shows all debug messages, which is what you usually
+need.
+.IP "\-e \fIfilter"
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
+.IP \-f
Trace child processes as they are created by
currently traced processes as a result of the fork(2)
or clone(2) system calls.
The new process is attached immediately.
-.TP
-.I \-F
-Load an alternate config file. Normally, /etc/ltrace.conf and
-~/.ltrace.conf will be read (the latter only if it exists).
-Use this option to load the given file or files instead of
-those two default files.
-.TP
-.I \-h, \-\-help
+.IP "\-F \fIpathlist"
+Contains a colon-separated list of paths. If a path refers to a
+directory, that directory is considered when prototype libraries are
+searched (see the section \fBPROTOTYPE LIBRARY DISCOVERY\fR). If it refers to
+a file, that file is imported implicitly to all loaded prototype
+libraries.
+.IP "\-h, \-\-help"
Show a summary of the options to ltrace and exit.
-.TP
-.I \-i
+.IP \-i
Print the instruction pointer at the time of the library call.
-.TP
-.I \-l, \-\-library library_pattern
+.IP "\-l, \-\-library \fIlibrary_pattern"
Display only calls to functions implemented by libraries that match
.I library_pattern.
Multiple library patters can be specified with several instances of
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
+.IP \-L
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
-.I nr
-number of spaces for each new nested call. Using this option makes
-the program flow visualization easy to follow.
-.TP
-.I \-o, \-\-output filename
-Write the trace output to the file
-.I filename
-rather than to stderr.
-.TP
-.I \-p pid
-Attach to the process with the process ID
-.I pid
-and begin tracing.
-.TP
-.I \-r
-Print a relative timestamp with each line of the trace.
-This records the time difference between the beginning of
-successive lines.
-.TP
-.I \-s strsize
+.IP "\-n, \-\-indent \fInr"
+Indent trace output by \fInr\fR spaces for each level of call
+nesting. Using this option makes the program flow visualization easy
+to follow. This indents uselessly also functions that never return,
+such as service functions for throwing exceptions in the C++ runtime.
+.IP "\-o, \-\-output \fIfilename"
+Write the trace output to the file \fIfilename\fR rather than to
+stderr.
+.IP "\-p \fIpid"
+Attach to the process with the process ID \fIpid\fR and begin tracing.
+This option can be used together with passing a command to execute.
+It is possible to attach to several processes by passing more than one
+option \-p.
+.IP \-r
+Print a relative timestamp with each line of the trace. This records
+the time difference between the beginning of successive lines.
+.IP "\-s \fIstrsize"
Specify the maximum string size to print (the default is 32).
-.TP
-.I \-S
+.IP \-S
Display system calls as well as library calls
-.TP
-.I \-t
+.IP \-t
Prefix each line of the trace with the time of day.
-.TP
-.I \-tt
+.IP \-tt
If given twice, the time printed will include the microseconds.
-.TP
-.I \-ttt
+.IP \-ttt
If given thrice, the time printed will include the microseconds and
the leading portion will be printed as the number of seconds since the
epoch.
-.TP
-.I \-T
+.IP \-T
Show the time spent inside each call. This records the time difference
between the beginning and the end of each call.
-.TP
-.I \-u username
+.IP "\-u \fIusername"
Run command with the userid, groupid and supplementary groups of
.IR username .
This option is only useful when running as root and enables the
correct execution of setuid and/or setgid binaries.
-.TP
-.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 filter
+.IP "\-w, --where \fInr"
+Show backtrace of \fInr\fR stack frames for each traced function. This
+option enabled only if libunwind support was enabled at compile time.
+.IP "\-x \fIfilter"
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
+.IP "\-V, \-\-version"
Show the version number of ltrace and exit.
.SH FILTER EXPRESSIONS
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.
+there was another rule \fB@\fR in front of it, which has the effect of
+tracing complement of given rule.
The above rules are used to construct the set of traced symbols. Each
candidate symbol is passed through the chain of above rules.
becomes \fIunmarked\fR again. If, after applying all rules, the
symbol is \fImarked\fR, it will be traced.
+.SH PROTOTYPE LIBRARY DISCOVERY
+
+When a library is mapped into the address space of a traced process,
+ltrace needs to know what the prototypes are of functions that this
+library implements. For purposes of ltrace, prototype really is a bit
+more than just type signature: it's also formatting of individual
+parameters and of return value. These prototypes are stored in files
+called prototype libraries.
+
+After a library is mapped, ltrace finds out what its SONAME is. It
+then looks for a file named SONAME.conf--e.g. protolib for libc.so.6
+would be in a file called libc.so.6.conf. When such file is found
+(more about where ltrace looks for these files is below), ltrace reads
+all prototypes stored therein. When a symbol table entry point (such
+as those traced by -x) is hit, the prototype is looked up in a
+prototype library corresponding to the library where the hit occured.
+When a library call (such as those traced by -e and -l) is hit, the
+prototype is looked up in all prototype libraries loaded for given
+process. That is necessary, because a library call is traced in a PLT
+table of a caller library, but the prototype is described at callee
+library.
+
+If a library has no SONAME, basename of library file is considered
+instead. For the main program binary, basename is considered as well
+(e.g. protolib for /bin/echo would be called echo.conf). If a name
+corresponding to soname (e.g. libc.so.6.conf) is not found, and the
+module under consideration is a shared library, ltrace also tries
+partial matches. Ltrace snips one period after another, retrying the
+search, until either a protolib is found, or X.so is all that's left.
+Thus libc.so.conf would be considered, but libc.conf not.
+
+When looking for a prototype library, ltrace potentially looks into
+several directories. On Linux, those are $XDG_CONFIG_HOME/ltrace,
+$HOME/.ltrace, \fIX\fR/ltrace for each \fIX\fR in $XDG_CONFIG_DIRS and
+/usr/share/ltrace. If the environment variable XDG_CONFIG_HOME is not
+defined, ltrace looks into $HOME/.config/ltrace instead.
+
+There's also a mechanism for loading legacy config files. If
+$HOME/.ltrace.conf exists it is imported to every loaded prototype
+library. Similarly for /etc/ltrace.conf. If both exist, both are
+imported, and $HOME/.ltrace.conf is consulted before /etc/ltrace.conf.
+
+If -F contains any directories, those are searched in precedence to
+the above system directories, in the same order in which they are
+mentioned in -F. Any files passed in -F are imported similarly to
+above legacy config files, before them.
+
+See ltrace.conf(5) for details on the syntax of ltrace prototype
+library files.

-Ltrace is a debugging program which runs a specified command until the
-command exits. While the command is executing, ltrace intercepts and
-records both the dynamic library calls called by the executed process
-and the signals received by the executed process. Ltrace can also
-intercept and print system calls executed by the process.
-
-You should install ltrace if you need a sysadmin tool for tracking the
-execution of processes.

+ * The calls are done directly from stubs, and the .plt entry
+ * (actually .iplt entry, these live in a special section) is resolved
+ * in advance before the binary starts. Because there's no PLT entry,
+ * we put the PLT breakpoints directly to the IFUNC resolver code, and
+ * then would like them to behave like ordinary PLT slots, including
+ * catching the point where these get resolved to unresolve them. So
+ * for the first call (which is the actual resolver call), we pretend
+ * that this breakpoint is artificial and has no associated symbol,
+ * and turn it on fully only after the first hit. Ideally we would
+ * trace that first call as well, but then the stepper, which tries to
+ * catch the point where the slot is resolved, would hit the return
+ * breakpoint and that's not currently handled well.
+ *
+ * On PPC32 with secure PLT, the address of IFUNC symbols in main
+ * binary actually isn't of the resolver, but of a PLT slot. We
+ * therefore have to locate the corresponding PLT relocation (which is
+ * of type R_PPC_IRELATIVE) and request that it be traced. The addend
+ * of that relocation is an address of resolver, and we request
+ * tracing of the xyz.IFUNC symbol there.
+ *
* 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
