  17 .Sh NAME
  18 .Nm libproc
  19 .Nd process control library
  20 .Sh SYNOPSIS
  21 .Lb libproc
  22 .In libproc.h
  23 .Sh DESCRIPTION
  24 The
  25 .Nm
  26 library provides consumers a general series of interfaces to inspect
  27 and control both live processes and core files.
  28 It is intended for introspection tools such as debuggers by providing a
  29 high-level interface to the /proc file system
  30 .Pf ( Xr proc 4 ) .
  31 .Pp
  32 The
  33 .Nm
  34 library provides interfaces that focus on:
  35 .Bl -bullet -offset indent
  36 .It
  37 Creating and attaching to live process, core files, and arbitrary ELF
  38 objects.
  39 .It
  40 Interrogating the state of a process or core file.
  41 .It
  42 Manipulating the current state of a process or thread.
  43 .It
  44 Interrogating the state of threads of a process or core file.
  45 .It
  46 Running system calls in the context of another process.
  47 .It
  48 Various utilities for iterating process and core file file descriptors,
  49 mappings, symbols, and more.
  50 .It
  51 Various utilities to support debugging tools.
  52 .El
  53 .Ss Live Processes
  54 The
  55 .Nm
  56 library can be used to manipulate running processes and to create new
  57 ones.
  58 To manipulate an existing process first
  59 .Em grab
  60 it with the
  61 .Fn Pgrab
  62 function.
  63 A process is generally stopped as a side effect of grabbing it.
  64 Callers must exercise caution, as if they do not use the library correctly, or
  65 they terminate unexpectedly, a process may remain stopped.
  66 .Pp
  67 Unprivileged users may only grab their own processes.
  68 Users with the privilege
  69 .Brq Sy PRIV_PROC_OWNER
  70 may manipulate processes that they do not own; however, additional
  71 restrictions as described in
  72 .Xr privileges 5
  73 apply.
  74 .Pp
  75 In addition, the
  76 .Fn Pcreate
  77 and
  78 .Fn Pxcreate
  79 functions may be used to create processes which are always controlled by
  80 the library.
  81 .Ss Core Files
  82 The
  83 .Nm
  84 library has the ability to open and interpret core files produced by
  85 processes on the system.
  86 Process core dump generation is controlled by the
  87 .Xr coreadm 1M
  88 command.
  89 In addition, the library has the ability to understand and interpret core dumps
  90 generated by Linux kernel and can provide a subset of its functionality on such
  91 core files, provided the original binary is also present.
  92 .Pp
  93 Not all functions in the
  94 .Nm
  95 library are valid for core files.
  96 In general, none of the commands which manipulate the current state of a process
  97 or thread or that try to force system calls on a victim process will work.
  98 Furthermore several of the information and iteration interfaces are limited
  99 based on the data that is available in the core file.
 100 For example, if the core file is of a process that omits the frame pointer, the
 101 ability to iterate the stack will be limited.
 102 .Pp
 103 Use the
 104 .Fn Pgrab_core
 105 or
 106 .Fn Pfgrab_core
 107 function to open a core file.
 108 Use the
 109 .Fn Pgrab_file
 110 function to open an ELF object file.
 111 This is useful for obtaining information stored in ELF headers and
 112 sections.
 113 .Ss Debug Information
 114 Many of the operations in the library rely on debug information being
 115 present in a process and its associated libraries.
 116 The library leverages symbol table information, CTF data
 117 .Pq Xr CTF 4
 118 sections, and frame unwinding information based on the use of an ABI
 119 defined frame pointer, e\&.g\&.
 120 .Sy %ebp
 121 and
 122 .Sy %rbp
 123 on x86 systems.
 124 .Pp
 125 Some software providers strip programs of this information or build
 126 their executables such that the information will not be present in a
 127 core dump.
 128 To deal with this fact, the library is able to consume information that is not
 129 present in the core file or the running process.
 130 It can both consume it from the underlying executable and it also supports
 131 finding it from related ELF objects that are linked to it via the
 132 .Sy .gnu_debuglink
 133 and the
 134 .Sy .note.gnu.build-id
 135 ELF sections.
 136 .Ss Iteration Interfaces
 137 The
 138 .Nm
 139 library provides the ability to iterate over the following aspects of a
 140 process or core file:
 141 .Bl -bullet -offset indent
 142 .It
 143 Active threads
 144 .It
 145 Active and zombie threads
 146 .It
 147 All non-system processes
 148 .It
 149 All process mappings
 150 .It
 151 All objects in a process
 152 .It
 153 The environment
 154 .It
 155 The symbol table
 156 .It
 157 Stack frames
 158 .It
 159 File Descriptors
 160 .El
 161 .Ss System Call Injection
 162 The
 163 .Nm
 164 library allows the caller to force system calls to be executed in the
 165 context of the running process.
 166 This can be used both as a tool for introspection, allowing one to get
 167 information outside its current context as well as performing modifications to a
 168 process.
 169 .Pp
 170 These functions run in the context of the calling process.
 171 This is often an easier way of getting non-exported information about a
 172 process from the system.
 173 For example, the
 174 .Xr pfiles 1
 175 command uses this interface to get more detailed information about a
 176 process's open file descriptors, which it would not have access to
 177 otherwise.
 178 .Sh INTERFACES
 179 The shared object
 180 .Sy libproc.so.1
 181 provides the public interfaces defined below.
 182 See

 347 .Sh PROCESS STATES
 348 Every process handle that exists in
 349 .Nm
 350 has a state.
 351 In some cases, such as for core files, these states are static.
 352 In other cases, such as handles that correspond to a running process or a
 353 created process, these states are dynamic and change based on actions taken in
 354 the library.
 355 The state can be obtained with the
 356 .Xr Pstate 3PROC
 357 function.
 358 .Pp
 359 The various states are:
 360 .Bl -tag -width Dv -offset indent
 361 .It Dv PS_RUN
 362 An actively running process.
 363 This may be a process that was obtained by creating it with functions such as
 364 .Xr Pcreate 3PROC
 365 or by grabbing an existing process such as
 366 .Xr Pgrab 3PROC .
 367 .It Dv PS_STOP
 368 An active process that is no longer executing.
 369 A process may stop for many reasons such as an explicit stop request (through
 370 .Xr pstop 1
 371 for example) or if a tracing event is hit.
 372 .Pp
 373 The reason a process is stopped may be obtained through the thread's
 374 .Vt lwpstatus_t
 375 structure read directly from /proc or obtained through the
 376 .Xr Lstatus 3PROC
 377 function.
 378 .It Dv PS_LOST
 379 Control over the process has been lost.
 380 This may happen when the process executes a new image requiring a different set
 381 of privileges.
 382 To resume control call
 383 .Xr Preopen 3PROC .
 384 For more information on losing control of a process, see
 385 .Xr proc 4 .
 386 .It Dv PS_UNDEAD
 387 A zombie process.
 388 It has terminated, but it has not been cleaned up yet by its parent.
 389 For more on the conditions of becoming a zombie, see
 390 .Xr exec 2 .
 391 .It Dv PS_DEAD
 392 Processes in this state are always core files.
 393 See the earlier section
 394 .Sx Core Files
 395 for more information on working with core files.
 396 .It Dv PS_IDLE
 397 A process that has never been run.
 398 This is always the case for handles that refer to files as the files cannot be
 399 executed.
 400 Those process handles are obtained through calling
 401 .Xr Pgrab_file 3PROC .
 402 .El
 403 .Pp
 404 Many functions relating to tracing processes, for example
 405 .Xr Psignal 3PROC ,
 406 .Xr Psetsignal 3PROC ,
 407 .Xr Psetfault 3PROC ,
 408 .Xr Psysentry 3PROC ,
 409 and others, mention that they only act upon
 410 .Em Active Processes .
 411 This specifically refers to processes whose state are in
 412 .Dv PS_RUN
 413 and
 414 .Dv PS_STOP .
 415 Process handles in the other states have no notion of settable tracing
 416 flags, though core files
 417 .Pq type Dv PS_DEAD
 418 may have a read-only snapshot of their tracing settings available.
 419 .Sh TYPES
 420 The
 421 .Nm
 422 library uses many types that come from the /proc file system
 423 .Pq Xr proc 4
 424 and the ELF format
 425 .Pq Xr elf 3ELF .
 426 However, it also defines the following types:
 427 .Pp
 428 .Vt struct ps_prochandle
 429 .Pp
 430 The
 431 .Vt struct ps_prochandle
 432 is an opaque handle to the library and the core element of control for a
 433 process.
 434 Consumers obtain pointers to a handle through the use of the
 435 .Fn Pcreate ,
 436 .Fn Pgrab ,
 437 and related functions.
 438 When a caller is done with a handle, then it should call one of the
 439 .Fn Pfree
 440 and
 441 .Fn Prelease
 442 functions to relinquish the handle, release associated resources, and
 443 potentially set the process to run again.
 444 .Pp
 445 .Vt struct ps_lwphandle
 446 .Pp
 447 The
 448 .Vt struct ps_lwphandle
 449 is analogous to the
 450 .Vt struct ps_prochandle ,
 451 but it represents the control of an individual thread, rather than a
 452 process.
 453 Consumers obtain pointers to a handle through the
 454 .Fn Lgrab
 455 function and relinquish it with the
 456 .Fn Lfree
 457 function.
 458 .Pp
 459 .Vt core_content_t
 460 .Pp
 461 The
 462 .Vt core_content_t
 463 is a value which describes the various content types of core files.
 464 These are used in functions such as
 465 .Xr Pcontent 3PROC
 466 and
 467 .Xr Pgcore 3PROC
 468 to describe and control the types of content that get included.
 469 Various content types may be included together through a bitwise-inclusive-OR.
 470 The default system core contents are controlled with the
 471 .Xr coreadm 1M
 472 tool.
 473 The following table lists the current set of core contents in the system, though
 474 the set may increase over time.
 475 The string after the macro is the human readable string that corresponds with
 476 the constant and is used by
 477 .Xr coreadm 1M ,
 478 .Xr proc_content2str 3PROC ,
 479 and
 480 .Xr proc_str2content 3PROC .
 481 .Bl -tag -offset indent -width indent
 482 .It Dv CC_CONTENT_STACK ("stack")
 483 The contents include the process stack.
 484 Note, this only covers the main thread's stack.
 485 The stack of other threads is covered by
 486 .Dv CC_CONTENT_ANON .
 487 .It Dv CC_CONTENT_HEAP ("heap")
 488 The contents include the process heap.
 489 .It Dv CC_CONTENT_SHFILE ("shfile")
 490 The contents include shared mappings that are backed by files (e.g.
 491 mapped through
 492 .Xr mmap 2
 493 with the
 494 .Dv MAP_SHARED
 495 flag).
 496 .It Dv CC_CONTENT_SHANNON ("shannon")
 497 The contents include shared mappings that are backed by anonymous memory
 498 (e.g. mapped through
 499 .Xr mmap 2
 500 with the
 501 .Dv MAP_SHARED
 502 and
 503 .Dv MAP_ANON
 504 flags).
 505 .It Dv CC_CONTENT_RODATA ("rodata")
 506 The contents include private read-only file mappings, such as shared
 507 library text.
 508 .It Dv CC_CONTENT_ANON ("anon")
 509 The contents include private anonymous mappings.
 510 This includes the stacks of threads which are not the main thread.
 511 .It Dv CC_CONTENT_SHM ("shm")
 512 The contents include system V shared memory.
 513 .It Dv CC_CONTENT_ISM ("ism")
 514 The contents include ISM (intimate shared memory) mappings.
 515 .It Dv CC_CONTENT_DISM ("dism")
 516 The contents include DISM (dynamic shared memory) mappings.
 517 .It Dv CC_CONTENT_CTF ("ctf")
 518 The contents include
 519 .Xr ctf 4
 520 (Compact C Type Format) information.
 521 Note, not all objects in the process may have CTF information available.
 522 .It Dv CC_CONTENT_SYMTAB ("symtab")
 523 The contents include the symbol table.
 524 Note, not all objects in the process may have a symbol table available.
 525 .It Dv CC_CONTENT_ALL ("all")
 526 This value indicates that all of the above content values are present.
 527 Note that additional values may be added in the future, in which case
 528 the value of the symbol will be updated to include them.
 529 Comparisons with
 530 .Dv CC_CONTENT_ALL
 531 should validate all the expected bits are set by an expression such as
 532 .Li (c & CC_CONTENT_ALL) == CC_CONTENT_ALL .
 533 .It Dv CC_CONTENT_NONE ("none")
 534 This value indicates that there is no content present.
 535 .It Dv CC_CONTENT_DEFAULT ("default")
 536 The content includes the following set of default values:
 537 .Dv CC_CONTENT_STACK ,
 538 .Dv CC_CONTENT_HEAP ,
 539 .Dv CC_CONTENT_ISM ,
 540 .Dv CC_CONTENT_DISM ,
 541 .Dv CC_CONTENT_SHM ,
 542 .Dv CC_CONTENT_SHANON ,
 543 .Dv CC_CONTENT_TEXT ,
 544 .Dv CC_CONTENT_DATA ,
 545 .Dv CC_CONTENT_RODATA ,
 546 .Dv CC_CONTENT_ANON ,
 547 .Dv CC_CONTENT_CTF ,
 548 and
 549 .Dv CC_CONTENT_SYMTAB .
 550 Note that the default may change.
 551 Comparisons with CC_CONTENT_DEFAULT should validate that all of the expected
 552 bits are set with an expression such as
 553 .Li (c\ &\ CC_CONTENT_DEFAULT)\ ==\ CC_CONTENT_DEFAULT .
 554 .It Dv CC_CONTENT_INVALID
 555 This indicates that the contents are invalid.

 560 The
 561 .Vt prfdinfo_t
 562 structure is used with the
 563 .Fn Pfdinfo_iter
 564 function which describes information about a file descriptor.
 565 The structure is defined as follows:
 566 .Bd -literal
 567 typedef struct prfdinfo {
 568         int             pr_fd;
 569         mode_t          pr_mode;

 582 } prfdinfo_t;
 583 .Ed
 584 .Pp
 585 The structure has similar information to that found in the
 586 .Sy stat
 587 structure that's used as part of the stat family of system calls,
 588 defined in
 589 .Xr stat 2 .
 590 The member
 591 .Sy pr_fd
 592 contains the number of the file descriptor of the file.
 593 The members
 594 .Fa pr_mode ,
 595 .Fa pr_uid ,
 596 .Fa pr_gid ,
 597 .Fa pr_ino ,
 598 and
 599 .Fa pr_size
 600 are the same as the members
 601 .Fa st_mode ,
 602 .Fa st_uid ,
 603 .Fa st_gid ,
 604 .Fa st_ino ,
 605 and
 606 .Fa st_size
 607 in the
 608 .Fa stat
 609 structure.
 610 .Pp
 611 The
 612 .Fa pr_major
 613 and
 614 .Fa pr_minor
 615 members contain the major and minor numbers of the device containing the
 616 directory for this file.
 617 This is similar to the
 618 .Fa st_dev
 619 member of the
 620 .Vt stat
 621 structure, except that it is broken out into its major and minor components.
 622 The
 623 .Fa pr_rmajor
 624 and
 625 .Fa pr_rminor
 626 members are similar in spirit to
 627 .Fa pr_major
 628 and
 629 .Fa pr_minor ;
 630 however, they are equivalent to the
 631 .Fa st_rdev
 632 member of the
 633 .Vt stat
 634 structure and thus have meaning for special character and block files.
 635 .Pp
 636 The
 637 .Fa pr_offset
 638 member contains the current seek offset of the file descriptor.
 639 The
 640 .Fa pr_fileflags
 641 and
 642 .Fa pr_fdflags
 643 members contain the flags that would have been returned by a call to
 644 .Xr fcntl 2
 645 with the arguments
 646 .Dv F_GETXFL
 647 and
 648 .Dv F_GETFD
 649 respectively.
 650 .Pp
 651 .Vt prsyminfo_t
 652 .Pp
 653 The
 654 .Vt prsyminfo_t
 655 structure is used with the various symbol look up functions
 656 .Fn Pxlookup_by_name ,
 657 .Fn Pxlookup_by_addr ,
 658 and
 659 .Fn Pxlookup_by_addr_resolved
 660 which describes additional information about a symbol.
 661 The structure is defined as follows:
 662 .Bd -literal
 663 typedef struct prsyminfo {
 664         const char      *prs_object;            /* object name */
 665         const char      *prs_name;              /* symbol name */
 666         Lmid_t          prs_lmid;               /* link map id */
 667         uint_t          prs_id;                 /* symbol id */
 668         uint_t          prs_table;              /* symbol table id */
 669 } prsyminfo_t;
 670 .Ed
 671 .Pp
 672 The member
 673 .Fa prs_object
 674 points to a string that contains the name of the object file, if known,
 675 that the symbol comes from.
 676 The member
 677 .Fa prs_name
 678 points to the name of the symbol, if known.
 679 This may be unknown due to a stripped binary that contains no symbol table.
 680 The member
 681 .Fa prs_lmid
 682 indicates the link map identifier that the symbol was found on.
 683 For more information on link map identifiers refer to the
 684 .%B Linker and Libraries Guide
 685 and
 686 .Xr dlopen 3C .
 687 .Pp
 688 The members
 689 .Fa prs_id
 690 and
 691 .Fa prs_table
 692 can be used to determine both the symbol table that the entry came from
 693 and which entry in the table it corresponds to.
 694 If the value of
 695 .Fa prs_table
 696 is
 697 .Dv PR_SYMTAB
 698 then it came from the ELF standard symbol table.
 699 However, if it is instead
 700 .Dv PR_DYNSYM ,
 701 then that indicates that it comes from the process's dynamic section.

 948 .Sh PROGRAMMING NOTES
 949 When working with live processes, whether from the
 950 .Xr Pgrab 3PROC
 951 or
 952 .Xr Pcreate 3PROC
 953 family of functions, there are some additional considerations.
 954 Importantly, if a process calls any of the
 955 .Xr exec 2
 956 suite of functions, much of the state information that is obtained,
 957 particularly that about mappings in the process will be invalid.
 958 Callers must ensure that they call
 959 .Xr Preset_maps 3PROC
 960 when they hold a process handle across an exec.
 961 In addition, users of the library should familiarize themselves with the
 962 .Sy PROGRAMMING NOTES
 963 section of the
 964 .Xr proc 4
 965 manual page, which discusses issues of privileges and security.
 966 .Sh DEBUGGING
 967 The library provides a means for obtaining additional debugging
 968 information.
 969 The output itself is not part of the
 970 .Nm
 971 library's stable interface.
 972 Setting the environment variable
 973 .Ev LIBPROC_DEBUG
 974 to some value will print information to standard error.
 975 For example,
 976 .Ev LIBPROC_DEBUG Ns = Ns Em please .
 977 .Sh LOCKING
 978 Most functions operate on a handle to a process in the form of a
 979 .Vt "struct ps_prochandle *" .
 980 Unless otherwise indicated, the library does not provide any
 981 synchronization for different routines that are operating on the
 982 .Sy same
 983 .Nm
 984 library handle.
 985 It is up to the caller to ensure that only a single thread is using a handle at
 986 any given time.
 987 Multiple threads may call
 988 .Nm
 989 library routines at the same time as long as each thread is using a
 990 different handle.
 991 .Pp
 992 Each individual function notes its
 993 .Sy MT-Level
 994 section.
 995 The MT-Level of a routine that matches the above description will refer to this
 996 manual page.
 997 If it does not, then it refers to the standard attributes in
 998 .Xr attributes 5 .
 999 .Sh INTERFACE STABILITY
1000 .Sy Uncommitted
1001 .Pp
1002 While the library is considered an uncommitted interface, and is still
1003 evolving, changes that break compatibility have been uncommon and this
1004 trend is expected to continue.
1005 It is documented to allow consumers, whether part of illumos or outside of it,
1006 to understand the libarary and make use of it with the understanding that
1007 changes may occur which break both source and binary compatibility.
