This specification is part of a family of specifications under the general title "Linux Standard Base". Developers of applications or implementations interested in using the LSB trademark should see the Free Standards Group Certification Policy for details. _________________________________________________________ Introduction The LSB defines a binary interface for application programs that are compiled and packaged for LSB-conforming implementations on many different hardware architectures. Since a binary specification shall include information specific to the computer processor architecture for which it is intended, it is not possible for a single document to specify the interface for all possible LSB-conforming implementations. Therefore, the LSB is a family of specifications, rather than a single one. This document should be used in conjunction with the documents it references. This document enumerates the system components it includes, but descriptions of those components may be included entirely or partly in this document, partly in other documents, or entirely in other reference documents. For example, the section that describes system service routines includes a list of the system routines supported in this interface, formal declarations of the data structures they use that are visible to applications, and a pointer to the underlying referenced specification for information about the syntax and semantics of each call. Only those routines not described in standards referenced by this document, or extensions to those standards, are described in the detail. Information referenced in this way is as much a part of this document as is the information explicitly included here. The specification carries a version number of either the form x.y or x.y.z. This version number carries the following meaning: * The first number (x) is the major version number. All versions with the same major version number should share binary compatibility. Any addition or deletion of a new library results in a new version number. Interfaces marked as deprecated may be removed from the specification at a major version change. * The second number (y) is the minor version number. Individual interfaces may be added if all certified implementations already had that (previously undocumented) interface. Interfaces may be marked as deprecated at a minor version change. Other minor changes may be permitted at the discretion of the LSB workgroup. * The third number (z), if present, is the editorial level. Only editorial changes should be included in such versions. Since this specification is a descriptive Application Binary Interface, and not a source level API specification, it is not possible to make a guarantee of 100% backward compatibility between major releases. However, it is the intent that those parts of the binary interface that are visible in the source level API will remain backward compatible from version to version, except where a feature marked as "Deprecated" in one release may be removed from a future release. Implementors are strongly encouraged to make use of symbol versioning to permit simultaneous support of applications conforming to different releases of this specification. I.

Documentation Conventions _________________________________________________________ Chapter 1. Scope 1.1. General The Linux Standard Base (LSB) defines a system interface for compiled applications and a minimal environment for support of installation scripts. Its purpose is to enable a uniform industry standard environment for high-volume applications conforming to the LSB. These specifications are composed of two basic parts: A common specification ("LSB-generic" or "generic LSB") describing those parts of the interface that remain constant across all implementations of the LSB, and an architecture-specific supplement ("LSB-arch" or "archLSB") describing the parts of the interface that vary by processor architecture. Together, the LSB-generic and the architecture-specific supplement for a single hardware architecture provide a complete interface specification for compiled application programs on systems that share a common hardware architecture. The LSB-generic document shall be used in conjunction with an architecture-specific supplement. Whenever a section of the LSB-generic specification shall be supplemented by architecture-specific information, the LSB-generic document includes a reference to the architecture supplement. Architecture supplements may also contain additional information that is not referenced in the LSB-generic document. The LSB contains both a set of Application Program Interfaces (APIs) and Application Binary Interfaces (ABIs). APIs may appear in the source code of portable applications, while the compiled binary of that application may use the larger set of ABIs. A conforming implementation shall provide all of the ABIs listed here. The compilation system may replace (e.g. by macro definition) certain APIs with calls to one or more of the underlying binary interfaces, and may insert calls to binary interfaces as needed. The LSB is primarily a binary interface definition. Not all of the source level APIs available to applications may be contained in this specification. _________________________________________________________ 1.2. Module Specific Scope This is the IA32 architecture specific Core module of the Linux Standards Base (LSB). This module supplements the generic LSB Core module with those interfaces that differ between architectures. Interfaces described in this module are mandatory except where explicitly listed otherwise. Core interfaces may be supplemented by other modules; all modules are built upon the core. _________________________________________________________ Chapter 2. References 2.1.

Requirements 3.1. Relevant Libraries The libraries listed in Table 3-1 shall be available on IA32 Linux Standard Base systems, with the specified runtime names. These names override or supplement the names specified in the generic LSB specification. The specified program interpreter, referred to as proginterp in this table, shall be used to load the shared libraries specified by DT_NEEDED entries at run time. Table 3-1. Standard Library Names Library Runtime Name libm libm.so.6 libdl libdl.so.2 libcrypt libcrypt.so.1 libz libz.so.1 libncurses libncurses.so.5 libutil libutil.so.1 libc libc.so.6 libpthread libpthread.so.0 proginterp /lib/ld-lsb.so.3 libgcc_s libgcc_s.so.1 These libraries will be in an implementation-defined directory which the dynamic linker shall search by default. _________________________________________________________ 3.2. LSB Implementation Conformance A conforming implementation is necessarily architecture specific, and must provide the interfaces specified by both the generic LSB Core specification and its relevant architecture specific supplement. Rationale: An implementation must provide at least the interfaces specified in these specifications. It may also provide additional interfaces. A conforming implementation shall satisfy the following requirements: * A processor architecture represents a family of related processors which may not have identical feature sets. The architecture specific supplement to this specification for a given target processor architecture describes a minimum acceptable processor. The implementation shall provide all features of this processor, whether in hardware or through emulation transparent to the application. * The implementation shall be capable of executing compiled applications having the format and using the system interfaces described in this document. * The implementation shall provide libraries containing the interfaces specified by this document, and shall provide a dynamic linking mechanism that allows these interfaces to be attached to applications at runtime. All the interfaces shall behave as specified in this document. * The map of virtual memory provided by the implementation shall conform to the requirements of this document. * The implementation's low-level behavior with respect to function call linkage, system traps, signals, and other such activities shall conform to the formats described in this document. * The implementation shall provide all of the mandatory interfaces in their entirety. * The implementation may provide one or more of the optional interfaces. Each optional interface that is provided shall be provided in its entirety. The product documentation shall state which optional interfaces are provided. * The implementation shall provide all files and utilities specified as part of this document in the format defined here and in other referenced documents. All commands and utilities shall behave as required by this document. The implementation shall also provide all mandatory components of an application's runtime environment that are included or referenced in this document. * The implementation, when provided with standard data formats and values at a named interface, shall provide the behavior defined for those values and data formats at that interface. However, a conforming implementation may consist of components which are separately packaged and/or sold. For example, a vendor of a conforming implementation might sell the hardware, operating system, and windowing system as separately packaged items. * The implementation may provide additional interfaces with different names. It may also provide additional behavior corresponding to data values outside the standard ranges, for standard named interfaces. _________________________________________________________ 3.3. LSB Application Conformance A conforming application is necessarily architecture specific, and must conform to both the generic LSB Core specification and its relevant architecture specific supplement. A conforming application shall satisfy the following requirements: * Its executable files shall be either shell scripts or object files in the format defined for the Object File Format system interface. * Its object files shall participate in dynamic linking as defined in the Program Loading and Linking System interface. * It shall employ only the instructions, traps, and other low-level facilities defined in the Low-Level System interface as being for use by applications. * If it requires any optional interface defined in this document in order to be installed or to execute successfully, the requirement for that optional interface shall be stated in the application's documentation. * It shall not use any interface or data format that is not required to be provided by a conforming implementation, unless: + If such an interface or data format is supplied by another application through direct invocation of that application during execution, that application shall be in turn an LSB conforming application. + The use of that interface or data format, as well as its source, shall be identified in the documentation of the application. * It shall not use any values for a named interface that are reserved for vendor extensions. A strictly conforming application shall not require or use any interface, facility, or implementation-defined extension that is not defined in this document in order to be installed or to execute successfully. _________________________________________________________ Chapter 4. Definitions For the purposes of this document, the following definitions, as specified in the ISO/IEC Directives, Part 2, 2001, 4th Edition, apply: can be able to; there is a possibility of; it is possible to cannot be unable to; there is no possibilty of; it is not possible to may is permitted; is allowed; is permissible need not it is not required that; no...is required shall is to; is required to; it is required that; has to; only...is permitted; it is necessary shall not is not allowed [permitted] [acceptable] [permissible]; is required to be not; is required that...be not; is not to be should it is recommended that; ought to should not it is not recommended that; ought not to _________________________________________________________ Chapter 5. Terminology For the purposes of this document, the following terms apply: archLSB The architectural part of the LSB Specification which describes the specific parts of the interface that are platform specific. The archLSB is complementary to the gLSB. Binary Standard The total set of interfaces that are available to be used in the compiled binary code of a conforming application. gLSB The common part of the LSB Specification that describes those parts of the interface that remain constant across all hardware implementations of the LSB. implementation-defined Describes a value or behavior that is not defined by this document but is selected by an implementor. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence of the value or behavior. An application that relies on such a value or behavior cannot be assured to be portable across conforming implementations. The implementor shall document such a value or behavior so that it can be used correctly by an application. Shell Script A file that is read by an interpreter (e.g., awk). The first line of the shell script includes a reference to its interpreter binary. Source Standard The set of interfaces that are available to be used in the source code of a conforming application. undefined Describes the nature of a value or behavior not defined by this document which results from use of an invalid program construct or invalid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations. unspecified Describes the nature of a value or behavior not specified by this document which results from use of a valid program construct or valid data input. The value or behavior may vary among implementations that conform to this document. An application should not rely on the existence or validity of the value or behavior. An application that relies on any particular value or behavior cannot be assured to be portable across conforming implementations. Other terms and definitions used in this document shall have the same meaning as defined in Chapter 3 of the Base Definitions volume of ISO POSIX (2003). _________________________________________________________ Chapter 6. Documentation Conventions Throughout this document, the following typographic conventions are used: function() the name of a function command the name of a command or utility CONSTANT a constant value parameter a parameter variable a variable Throughout this specification, several tables of interfaces are presented. Each entry in these tables has the following format: name the name of the interface (symver) An optional symbol version identifier, if required. [refno] A reference number indexing the table of referenced specifications that follows this table. For example, forkpty(GLIBC_2.0) [SUSv3] refers to the interface named forkpty() with symbol version GLIBC_2.0 that is defined in the SUSv3 reference. Note: Symbol versions are defined in the architecture specific supplements only. II. Executable and Linking Format (ELF) Table of Contents 7. Introduction 8. Low Level System Information 8.1.

Introduction Executable and Linking Format (ELF) defines the object format for compiled applications. This specification supplements the information found in System V ABI Update and System V ABI, IA32 Supplement, and is intended to document additions made since the publication of that document. _________________________________________________________ Chapter 8. Low Level System Information 8.1. Machine Interface 8.1.1. Processor Architecture The IA32 Architecture is specified by the following documents * Intel® Architecture Software Developer's Manual Volume 1 * Intel® Architecture Software Developer's Manual Volume 2 * Intel® Architecture Software Developer's Manual Volume 3 Only the features of the Intel486 processor instruction set may be assumed to be present. An application should determine if any additional instruction set features are available before using those additional features. If a feature is not present, then a conforming application shall not use it. Conforming applications may use only instructions which do not require elevated privileges. Conforming applications shall not invoke the implementations underlying system call interface directly. The interfaces in the implementation base libraries shall be used instead. Rationale: Implementation-supplied base libraries may use the system call interface but applications must not assume any particular operating system or kernel version is present. Applications conforming to this specification shall provide feedback to the user if a feature that is required for correct execution of the application is not present. Applications conforming to this specification should attempt to execute in a diminished capacity if a required instruction set feature is not present. This specification does not provide any performance guarantees of a conforming system. A system conforming to this specification may be implemented in either hardware or software. _________________________________________________________ 8.1.2. Data Representation LSB-conforming applications shall use the data representation as defined in Chapter 3 of the System V ABI, IA32 Supplement. _________________________________________________________ 8.1.2.1. Byte Ordering LSB-conforming systems and applications shall use the bit and byte ordering rules specified in Section 1.3.1 of the Intel® Architecture Software Developer's Manual Volume 1. _________________________________________________________ 8.1.2.2. Fundamental Types In addition to the fundamental types specified in Chapter 3 of the System V ABI, IA32 Supplement, a 64 bit data type is defined here. Table 8-1.

Data Definitions for libc This section defines global identifiers and their values that are associated with interfaces contained in libc. These definitions are organized into groups that correspond to system headers. This convention is used as a convenience for the reader, and does not imply the existence of these headers, or their content. Where an interface is defined as requiring a particular system header file all of the data definitions for that system header file presented here shall be in effect. This section gives data definitions to promote binary application portability, not to repeat source interface definitions available elsewhere. System providers and application developers should use this ABI to supplement - not to replace - source interface definition specifications. This specification uses the ISO C (1999) C Language as the reference programming language, and data definitions are specified in ISO C format. The C language is used here as a convenient notation. Using a C language description of these data objects does not preclude their use by other programming languages. _________________________________________________________ 11.3.1. arpa/inet.h extern uint32_t htonl(uint32_t);
