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 `' 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. - debian/rules debian/control DEB_AUTO_UPDATE_DEBIAN_CONTROL:=yes diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..6e46949 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,157 @@ +# This file is part of ltrace. +# Copyright (C) 2012 Petr Machata, Red Hat Inc. +# Copyright (C) 2010 Marc Kleine-Budde, Pengutronix +# Copyright (C) 2010 Zachary T Welch, CodeSourcery +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of the +# License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, but +# WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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.

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.

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.

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.

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.

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, ... } } } }) = +.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( +.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. + +.TP +.B void\fR func_charp_string\fB(char\fR str\fB[]); +.B void\fR func_charp_string\fB(string); + +.PP +.B enum\fR e_foo \fB{\fRRED\fB, \fRGREEN\fB, \fRBLUE\fB}; +.br +.B void\fR func_enum\fB(enum\fR e_foo bar\fB);\fR +.RS +.B void\fR func_enum\fB(enum(\fRRED\fB,\fRGREEN\fB,\fRBLUE\fB));\fR +.RS +- or - +.RE +.B typedef\fR e_foo \fB= enum(\fRRED\fB,\fRGREEN\fB,\fRBLUE\fB);\fR +.br +.B void\fR func_enum\fB(\fRe_foo\fB);\fR +.RE + +.TP +.B void\fR func_arrayi\fB(int\fR arr\fB[],\fR int len\fB); +.B void\fR func_arrayi\fB(array(int,arg2)*,int); + +.PP +.B struct\fR S1 \fB{float\fR f\fB; char\fR a\fB; char \fRb\fB;}; +.br +.B struct\fR S2 \fB{char\fR str\fB[\fR6\fB]; float\fR f\fB;}; +.br +.B struct\fR S1 func_struct\fB(int \fRa\fB, struct \fRS2\fB, double \fRd\fB); +.RS +.B struct(float,char,char)\fR func_struct_2\fB(int, struct(string(array(char, \fR6\fB)),float), double); +.RE + +.SH AUTHOR +Petr Machata diff --git a/ltrace.h b/ltrace.h index 5e43ba5..ee7e27b 100644 --- a/ltrace.h +++ b/ltrace.h @@ -1,3 +1,26 @@ +/* + * This file is part of ltrace. + * Copyright (C) 2009 Juan Cespedes + * + * This program is free software; you can redistribute it and/or + * modify it under the terms of the GNU General Public License as + * published by the Free Software Foundation; either version 2 of the + * License, or (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

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. + * (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.
