LIBPROC(3LIB) Interface Libraries LIBPROC(3LIB)

libproc — process control library

Process Control Library (libproc, -lproc)
#include <libproc.h>

The libproc library provides consumers a general series of interfaces to inspect and control both live processes and core files. It is intended for introspection tools such as debuggers by providing a high-level interface to the /proc file system (proc(5)).

The libproc library provides interfaces that focus on:

The libproc library can be used to manipulate running processes and to create new ones. To manipulate an existing process first it with the () function. A process is generally stopped as a side effect of grabbing it. Callers must exercise caution, as if they do not use the library correctly, or they terminate unexpectedly, a process may remain stopped.

Unprivileged users may only grab their own processes. Users with the privilege {} may manipulate processes that they do not own; however, additional restrictions as described in privileges(7) apply.

In addition, the () and Pxcreate() functions may be used to create processes which are always controlled by the library.

The libproc library has the ability to open and interpret core files produced by processes on the system. Process core dump generation is controlled by the coreadm(8) command. In addition, the library has the ability to understand and interpret core dumps generated by Linux kernel and can provide a subset of its functionality on such core files, provided the original binary is also present.

Not all functions in the libproc library are valid for core files. In general, none of the commands which manipulate the current state of a process or thread or that try to force system calls on a victim process will work. Furthermore several of the information and iteration interfaces are limited based on the data that is available in the core file. For example, if the core file is of a process that omits the frame pointer, the ability to iterate the stack will be limited.

Use the () or Pfgrab_core() function to open a core file. Use the Pgrab_file() function to open an ELF object file. This is useful for obtaining information stored in ELF headers and sections.

Many of the operations in the library rely on debug information being present in a process and its associated libraries. The library leverages symbol table information, CTF data (ctf(5)) sections, and frame unwinding information based on the use of an ABI defined frame pointer, e.g. and on x86 systems.

The libproc library provides the ability to iterate over the following aspects of a process or core file:

  • Active threads
  • Active and zombie threads
  • All non-system processes
  • All process mappings
  • All objects in a process
  • The environment
  • The symbol table
  • Stack frames
  • File Descriptors

System Call Injection

The libproc library allows the caller to force system calls to be executed in the context of the running process. This can be used both as a tool for introspection, allowing one to get information outside its current context as well as performing modifications to a process.

These functions run in the context of the calling process. This is often an easier way of getting non-exported information about a process from the system. For example, the pfiles(1) command uses this interface to get more detailed information about a process's open file descriptors, which it would not have access to otherwise.

The shared object provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces. Functions are organized into categories that describe their purpose. Individual functions are documented in their own manual pages.

The following routines are related to creating library handles, grabbing cores, processes, and threads, and releasing those resources.

The following routines obtain information about a process and allow manipulation of the process itself.

The following routines obtain information about a thread and allow manipulation of the thread itself.

System Call Injection

The following routines are used to inject specific system calls and have them run in the context of a process.

These routines are used to iterate over the contents of a process.

The following routines are utilities that are useful to consumers of the library.

The following routines are specific to the x86, 32-bit and 64-bit, versions of the libproc library.

The following functions are specific to the SPARC, 32-bit and 64-bit, versions of the libproc library.

The following functions are specific to the 64-bit SPARC version of the libproc library.

Every process handle that exists in libproc has a state. In some cases, such as for core files, these states are static. In other cases, such as handles that correspond to a running process or a created process, these states are dynamic and change based on actions taken in the library. The state can be obtained with the Pstate(3PROC) function.

The various states are:

An actively running process. This may be a process that was obtained by creating it with functions such as Pcreate(3PROC) or by grabbing an existing process such as Pgrab(3PROC).
An active process that is no longer executing. A process may stop for many reasons such as an explicit stop request (through pstop(1) for example) or if a tracing event is hit.

The reason a process is stopped may be obtained through the thread's lwpstatus_t structure read directly from /proc or obtained through the Lstatus(3PROC) function.

Control over the process has been lost. This may happen when the process executes a new image requiring a different set of privileges. To resume control call Preopen(3PROC). For more information on losing control of a process, see proc(5).
A zombie process. It has terminated, but it has not been cleaned up yet by its parent. For more on the conditions of becoming a zombie, see exec(2).
Processes in this state are always core files. See the earlier section Core Files for more information on working with core files.
A process that has never been run. This is always the case for handles that refer to files as the files cannot be executed. Those process handles are obtained through calling Pgrab_file(3PROC).

Many functions relating to tracing processes, for example Psignal(3PROC), Psetsignal(3PROC), Psetfault(3PROC), Psysentry(3PROC), and others, mention that they only act upon . This specifically refers to processes whose state are in PS_RUN and PS_STOP. Process handles in the other states have no notion of settable tracing flags, though core files (type PS_DEAD) may have a read-only snapshot of their tracing settings available.

The libproc library uses many types that come from the /proc file system (proc(5)) and the ELF format (elf(3ELF)). However, it also defines the following types:

struct ps_prochandle

The struct ps_prochandle is an opaque handle to the library and the core element of control for a process. Consumers obtain pointers to a handle through the use of the (), Pgrab(), and related functions. When a caller is done with a handle, then it should call one of the Pfree() and Prelease() functions to relinquish the handle, release associated resources, and potentially set the process to run again.

struct ps_lwphandle

The struct ps_lwphandle is analogous to the struct ps_prochandle, but it represents the control of an individual thread, rather than a process. Consumers obtain pointers to a handle through the () function and relinquish it with the Lfree() function.

core_content_t

The core_content_t is a value which describes the various content types of core files. These are used in functions such as Pcontent(3PROC) and Pgcore(3PROC) to describe and control the types of content that get included. Various content types may be included together through a bitwise-inclusive-OR. The default system core contents are controlled with the coreadm(8) tool. The following table lists the current set of core contents in the system, though the set may increase over time. The string after the macro is the human readable string that corresponds with the constant and is used by coreadm(8), proc_content2str(3PROC), and proc_str2content(3PROC).

The contents include the process stack. Note, this only covers the main thread's stack. The stack of other threads is covered by CC_CONTENT_ANON.
The contents include the process heap.
The contents include shared mappings that are backed by files (e.g. mapped through mmap(2) with the MAP_SHARED flag).
The contents include shared mappings that are backed by anonymous memory (e.g. mapped through mmap(2) with the MAP_SHARED and MAP_ANON flags).
The contents include private read-only file mappings, such as shared library text.
The contents include private anonymous mappings. This includes the stacks of threads which are not the main thread.
The contents include system V shared memory.
The contents include ISM (intimate shared memory) mappings.
The contents include DISM (dynamic shared memory) mappings.
The contents include ctf(5) (Compact C Type Format) information. Note, not all objects in the process may have CTF information available.
The contents include the symbol table. Note, not all objects in the process may have a symbol table available.
This value indicates that all of the above content values are present. Note that additional values may be added in the future, in which case the value of the symbol will be updated to include them. Comparisons with CC_CONTENT_ALL should validate all the expected bits are set by an expression such as (c & CC_CONTENT_ALL) == CC_CONTENT_ALL.
This value indicates that there is no content present.
The content includes the following set of default values: CC_CONTENT_STACK, CC_CONTENT_HEAP, CC_CONTENT_ISM, CC_CONTENT_DISM, CC_CONTENT_SHM, CC_CONTENT_SHANON, CC_CONTENT_TEXT, CC_CONTENT_DATA, CC_CONTENT_RODATA, CC_CONTENT_ANON, CC_CONTENT_CTF, and CC_CONTENT_SYMTAB. Note that the default may change. Comparisons with CC_CONTENT_DEFAULT should validate that all of the expected bits are set with an expression such as (c & CC_CONTENT_DEFAULT) == CC_CONTENT_DEFAULT.
This indicates that the contents are invalid.

prfdinfo_t

The prfdinfo_t structure is used with the (), proc_fdwalk(), proc_fdinfowalk() and proc_get_fdinfo() functions and describes information about a file descriptor. The structure is defined as follows:

typedef struct prfdinfo {
    int		pr_fd;		/* file descriptor number */
    mode_t	pr_mode;	/* (see st_mode in stat(2)) */
    ino64_t	pr_ino;		/* inode number */
    off64_t	pr_size;	/* file size */
    off64_t	pr_offset;	/* current offset */
    uid_t	pr_uid;		/* owner's user id */
    gid_t	pr_gid;		/* owner's group id */
    major_t	pr_major;	/* major number of device */
    minor_t	pr_minor;	/* minor number of device */
    major_t	pr_rmajor;	/* major number (if special file) */
    minor_t	pr_rminor;	/* minor number (if special file) */
    int		pr_fileflags;	/* (see F_GETXFL in fcntl(2)) */
    int		pr_fdflags;	/* (see F_GETFD in fcntl(2)) */
    short	pr_locktype;	/* (see F_GETLK in fcntl(2)) */
    pid_t	pr_lockpid;	/* process holding file lock */
    int		pr_locksysid;	/* sysid of locking process */
    pid_t	pr_peerpid;	/* peer process (socket, door) */
    int		pr_filler[25];	/* reserved for future use */
    char	pr_peername[PRFNSZ];	/* peer process name */
#if    __STDC_VERSION__ >= 199901L
    uint8_t	pr_misc[];	/* self describing structures */
else
    uint8_t	pr_misc[1];	/* self describing structures */
#endif
} prfdinfo_t;

The structure has similar information to that found in the structure that's used as part of the stat family of system calls, defined in stat(2). The member contains the number of the file descriptor of the file. The members pr_mode, pr_uid, pr_gid, pr_ino, and pr_size are the same as the members st_mode, st_uid, st_gid, st_ino, and st_size in the stat structure.

The pr_major and pr_minor members contain the major and minor numbers of the device containing the directory for this file. This is similar to the st_dev member of the stat structure, except that it is broken out into its major and minor components. The pr_rmajor and pr_rminor members are similar in spirit to pr_major and pr_minor; however, they are equivalent to the st_rdev member of the stat structure and thus have meaning for special character and block files.

The pr_offset member contains the current seek offset of the file descriptor. The pr_fileflags and pr_fdflags members contain the flags that would have been returned by a call to fcntl(2) with the arguments F_GETXFL and F_GETFD respectively.

The pr_locktype, pr_lockpid, and pr_locksysid contain the information that would have been returned by a call to fcntl(2) with an argument of F_GETLK.

The pr_peerpid and pr_peername members contain the process ID and name of any peer endpoint of a connection-oriented socket or stream fd. This information is the same as that which would be returned by a call to getpeerucred(3C)

The pr_misc member contains miscellaneous additional data relating to the file descriptor. The format of these data is described in proc(5).

prsyminfo_t

The prsyminfo_t structure is used with the various symbol look up functions (), Pxlookup_by_addr(), and Pxlookup_by_addr_resolved() which describes additional information about a symbol. The structure is defined as follows:

typedef struct prsyminfo {
        const char      *prs_object;            /* object name */
        const char      *prs_name;              /* symbol name */
        Lmid_t          prs_lmid;               /* link map id */
        uint_t          prs_id;                 /* symbol id */
        uint_t          prs_table;              /* symbol table id */
} prsyminfo_t;

The member prs_object points to a string that contains the name of the object file, if known, that the symbol comes from. The member prs_name points to the name of the symbol, if known. This may be unknown due to a stripped binary that contains no symbol table. The member prs_lmid indicates the link map identifier that the symbol was found on. For more information on link map identifiers refer to the Linker and Libraries Guide and dlopen(3C).

The members prs_id and prs_table can be used to determine both the symbol table that the entry came from and which entry in the table it corresponds to. If the value of prs_table is PR_SYMTAB then it came from the ELF standard symbol table. However, if it is instead PR_DYNSYM, then that indicates that it comes from the process's dynamic section.

proc_lwp_f

The proc_lwp_f is a function pointer type that is used with the () function. It is defined as typedef int (void *, const lwpstatus_t *);. The first argument is a pointer to an argument that the user specifies, while the second has the thread's status information and is defined in proc(5).

The first argument is a pointer to an argument that the user specifies. The second argument is a pointer to the struct ps_prochandle that the callback was passed to. The third argument is the address of the environment variable in the process. The fourth argument is the environment variable. Values in the environment follow the convention of the form . For more information on environment variables see exec(2) and environ(7). For additional information on using this type, see Penv_iter(3PROC).

proc_sym_f

The proc_sym_f is a function pointer type that is used with the (), Psymbol_iter_by_addr(), Psymbol_iter_by_name(), and Psymbol_iter_by_lmid() functions. It is defined as typedef int (void *, const GElf_Sym *, const char *);. The first argument is a pointer to an argument that the user supplies. The second argument is a pointer to the ELF symbol information in a 32-bit and 64-bit neutral form. See elf(3ELF) and gelf(3ELF) for more information on it.

The first three arguments are identical to those of proc_sym_f. The final argument contains additional information about the symbol itself. The members of the prsyminfo_t are defined earlier in this section. For additional information on using this type, see Pxsymbol_iter(3PROC).

proc_stack_f

The proc_stack_f is a function pointer type that is used with the () function. It is defined as typedef int (void *, prgregset_t, uint_t, const long *);. The first argument is a pointer to an argument that the user specifies. The second argument's contents are platform specific. The registers that contain stack information, usually the stack pointer and frame pointer, will be filled in to point to an entry. The prgregset_t is defined in proc(5).

The third argument contains the number of arguments to the current stack frame and the fourth argument contains an array of addresses that correspond to the arguments to that stack function. The value of the third argument dictates the number of entries in the fourth argument. For additional information on using this type, see Pstack_iter(3PROC).

proc_fdinfo_f

The proc_fdinfo_f is a function pointer type that is used with the () function. It is defined as typedef int (void *, prfdinfo_t *);. The first argument is a pointer to an argument that the user specifies. The second argument contains information about an open file descriptor. The members of the prfdinfo_t are defined earlier in this section. For additional information on using this type, see Pfdinfo_iter(3PROC).

When working with live processes, whether from the Pgrab(3PROC) or Pcreate(3PROC) family of functions, there are some additional considerations. Importantly, if a process calls any of the exec(2) suite of functions, much of the state information that is obtained, particularly that about mappings in the process will be invalid. Callers must ensure that they call Preset_maps(3PROC) when they hold a process handle across an exec. In addition, users of the library should familiarize themselves with the section of the proc(5) manual page, which discusses issues of privileges and security.

The library provides a means for obtaining additional debugging information. The output itself is not part of the libproc library's stable interface. Setting the environment variable LIBPROC_DEBUG to some value will print information to standard error. For example, LIBPROC_DEBUG=.

Most functions operate on a handle to a process in the form of a struct ps_prochandle *. Unless otherwise indicated, the library does not provide any synchronization for different routines that are operating on the libproc library handle. It is up to the caller to ensure that only a single thread is using a handle at any given time. Multiple threads may call libproc library routines at the same time as long as each thread is using a different handle.

Each individual function notes its section. The MT-Level of a routine that matches the above description will refer to this manual page. If it does not, then it refers to the standard attributes in attributes(7).

While the library is considered an uncommitted interface, and is still evolving, changes that break compatibility have been uncommon and this trend is expected to continue. It is documented to allow consumers, whether part of illumos or outside of it, to understand the library and make use of it with the understanding that changes may occur which break both source and binary compatibility.
