16 16 .Os
17 17 .Sh NAME
18 18 .Nm libproc
19 19 .Nd process control library
20 20 .Sh SYNOPSIS
21 21 .Lb libproc
22 22 .In libproc.h
23 23 .Sh DESCRIPTION
24 24 The
25 25 .Nm
26 26 library provides consumers a general series of interfaces to inspect
27 27 and control both live processes and core files. It is intended for
28 28 introspection tools such as debuggers by providing a high-level
29 29 interface to the /proc file system
30 30 .Pf ( Xr proc 4 ) .
31 31 .Pp
32 32 The
33 33 .Nm
34 34 library provides interfaces that focus on:
35 35 .Bl -bullet -offset indent
36 36 .It
37 37 Creating and attaching to live process, core files, and arbitrary ELF
38 38 objects.
39 39 .It
40 40 Interrogating the state of a process or core file.
41 41 .It
42 42 Manipulating the current state of a process or thread.
43 43 .It
44 44 Interrogating the state of threads of a process or core file.
45 45 .It
46 46 Running system calls in the context of another process.
47 47 .It
48 48 Various utilities for iterating process and core file file descriptors,
49 49 mappings, symbols, and more.
50 50 .It
51 51 Various utilities to support debugging tools.
52 52 .El
53 53 .Ss Live Processes
54 54 The
55 55 .Nm
56 56 library can be used to manipulate running processes and to create new
57 57 ones. To manipulate an existing process first
58 58 .Em grab
59 59 it with the
60 60 .Em Pgrab
61 61 function. A process is generally stopped as a side effect of grabbing
62 62 it. Callers must exercise caution, as if they do not use the library
63 63 correctly, or they terminate unexpectedly, a process may remain
64 64 stopped.
65 65 .Pp
66 66 Unprivileged users may only grab their own processes. Users with the
67 67 privilege
68 68 .Sy PRIV_PROC_OWNER
69 69 may manipulate processes that they do not own; however, additional
70 70 restrictions as described in
71 71 .Xr privileges 5
72 72 apply.
73 73 .Pp
74 74 In addition, the
75 75 .Fn Pcreate
76 76 and
77 77 .Fn Pxcreate
78 78 functions may be used to create processes which are always controlled by
79 79 the library.
80 80 .Ss Core Files
81 81 The
82 82 .Nm
83 83 library has the ability to open and interpret core files produced by
84 84 processes on the system. Process core dump generation is controlled by
85 85 the
86 86 .Xr coreadm 1M
87 87 command. In addition, the library has the ability to understand and
88 88 interpret core dumps generated by Linux kernel and can provide a subset
89 89 of its functionality on such core files, provided the original binary is
90 90 also present.
91 91 .Pp
92 92 Not all functions in the
93 93 .Nm
94 94 library are valid for core files. In general, none of the commands
95 95 which manipulate the current state of a process or thread or that try
96 96 to force system calls on a victim process will work. Furthermore
97 97 several of the information and iteration interfaces are limited based
98 98 on the data that is available in the core file. For example, if the
99 99 core file is of a process that omits the frame pointer, the ability to
100 100 iterate the stack will be limited.
101 101 .Pp
102 102 Use the
103 103 .Fn Pgrab_core
104 104 or
105 105 .Fn Pfgrab_core
106 106 function to open a core file. Use the
107 107 .Fn Pgrab_file
108 108 function to open an ELF object file.
109 109 This is useful for obtaining information stored in ELF headers and
110 110 sections.
111 111 .Ss Debug Information
112 112 Many of the operations in the library rely on debug information being
113 113 present in a process and its associated libraries. The library
114 114 leverages symbol table information, CTF data
115 115 .Pf ( Xr CTF 4 )
116 116 sections, and frame unwinding information based on the use of an ABI
117 117 defined frame pointer, eg.
118 118 .Sy %ebp
119 119 and
120 120 .Sy %rbp
121 121 on x86 systems.
122 122 .Pp
123 123 Some software providers strip programs of this information or build
124 124 their executables such that the information will not be present in a
125 125 core dump. To deal with this fact, the library is able to consume
126 126 information that is not present in the core file or the running
127 127 process. It can both consume it from the underlying executable and it
128 128 also supports finding it from related ELF objects that are linked to
129 129 it via the
130 130 .Sy .gnu_debuglink
131 131 and the
132 132 .Sy .note.gnu.build-id
133 133 ELF sections.
134 134 .Ss Iteration Interfaces
135 135 The
136 136 .Nm
137 137 library provides the ability to iterate over the following aspects of a
138 138 process or core file:
139 139 .Bl -bullet -offset indent
140 140 .It
141 141 Active threads
142 142 .It
143 143 Active and zombie threads
144 144 .It
145 145 All non-system processes
146 146 .It
147 147 All process mappings
148 148 .It
149 149 All objects in a process
150 150 .It
151 151 The environment
152 152 .It
153 153 The symbol table
154 154 .It
155 155 Stack frames
156 156 .It
157 157 File Descriptors
158 158 .El
159 159 .Ss System Call Injection
160 160 The
161 161 .Nm
162 162 library allows the caller to force system calls to be executed in the
163 163 context of the running process. This can be used both as a tool for
164 164 introspection, allowing one to get information outside its current
165 165 context as well as performing modifications to a process.
166 166 .Pp
167 167 These functions run in the context of the calling process. This is
168 168 often an easier way of getting non-exported information about a
169 169 process from the system. For example, the
170 170 .Xr pfiles 1
171 171 command uses this interface to get more detailed information about a
172 172 process's open file descriptors, which it would not have access to
173 173 otherwise.
174 174 .Sh INTERFACES
175 175 The shared object
176 176 .Sy libproc.so.1
177 177 provides the public interfaces defined below. See
178 178 .Xr Intro 3
179 179 for additional information on shared object interfaces. Functions are
180 180 organized into categories that describe their purpose. Individual
181 181 functions are documented in their own manual pages.

341 342 .Sh PROCESS STATES
342 343 Every process handle that exists in
343 344 .Nm
344 345 has a state. In some cases, such as for core files, these states are
345 346 static. In other cases, such as handles that correspond to a
346 347 running process or a created process, these states are dynamic and
347 348 change based on actions taken in the library. The state can be obtained
348 349 with the
349 350 .Xr Pstate 3PROC
350 351 function.
351 352 .Pp
352 353 The various states are:
353 354 .Bl -tag -width Dv -offset indent
354 355 .It Dv PS_RUN
355 356 An actively running process. This may be a process that was obtained
356 357 by creating it with functions such as
357 358 .Xr Pcreate 3PROC
358 359 or by grabbing an existing process such as
359 360 .Xr Pgrab 3PROC .
360 361 .It Dv PS_STOP
361 362 An active process that is no longer executing. A process may stop for
362 363 many reasons such as an explicit stop request (through
363 364 .Xr pstop 1
364 365 for example) or if a tracing event is hit.
365 366 .Pp
366 367 The reason a process is stopped may be obtained through the thread's
367 368 .Sy lwpstatus_t
368 369 structure read directly from /proc or obtained through the
369 370 .Xr Lstatus 3PROC
370 371 function.
371 372 .It Dv PS_LOST
372 373 Control over the process has been lost. This may happen when the
373 374 process executes a new image requiring a different set of privileges.
374 375 To resume control call
375 376 .Xr Preopen 3PROC . For more information on losing control of a process,
376 377 see
377 378 .Xr proc 4 .
378 379 .It DV PS_UNDEAD
379 380 A zombie process. It has terminated, but it has not been cleaned up
380 381 yet by its parent. For more on the conditions of becoming a zombie,
381 382 see
382 383 .Xr exec 2 .
383 384 .It DV_PS_DEAD
384 385 Processes in this state are always core files. See the earlier section
385 386 .Sx Core Files
386 387 for more information on working with core files.
387 388 .It Dv PS_IDLE
388 389 A process that has never been run. This is always the case for handles
389 390 that refer to files as the files cannot be executed. Those process
390 391 handles are obtained through calling
391 392 .Xr Pgrab_file 3PROC .
392 393 .El
393 394 .Pp
394 395 Many functions relating to tracing processes, for example
395 396 .Xr Psignal 3PROC ,
396 397 .Xr Psetsignal 3PROC ,
397 398 .Xr Psetfault 3PROC ,
398 399 .Xr Psetentry 3PROC ,
399 400 and others, mention that they only act upon
400 401 .Em Active Processes .
401 402 This specifically refers to processes whose state are in
402 403 .Dv PS_RUN
403 404 and
404 405 .Dv PS_STOP .
405 406 Process handles in the other states have no notion of settable tracing
406 407 flags, though core files
407 408 .Pf ( type Dv PS_DEAD ) ,
408 409 =======
409 410 may have a read-only snapshot of their tracing settings available.
410 411 .Sh TYPES
411 412 The
412 413 .Nm
413 414 library uses many types that come from the /proc file system
414 415 .Pf ( Xr proc 4 )
415 416 and the ELF format
416 417 .Pf ( Xr elf 3ELF ) .
417 418 However, it also defines the following types:
418 419 .Pp

420 421 .Pp
421 422 The
422 423 .Sy struct ps_prochandle
423 424 is an opaque handle to the library and the core element of control for a
424 425 process. Consumers obtain pointers to a handle through the use of the
425 426 .Fn Pcreate ,
426 427 .Fn Pgrab ,
427 428 and related functions. When a caller is done with a handle, then it
428 429 should call one of the
429 430 .Fn Pfree
430 431 and
431 432 .Fn Prelease
432 433 functions to relinquish the handle, release associated resources, and
433 434 potentially set the process to run again.

437 438 The
438 439 .Sy struct ps_lwphandle
439 440 is analogous to the
440 441 .Sy struct ps_prochandle ,
441 442 but it represents the control of an individual thread, rather than a
442 443 process. Consumers obtain pointers to a handle through the
443 444 .Fn Lgrab
444 445 function and relinquish it with the
445 446 .Fn Lfree
446 447 function.

449 450 .Pp
450 451 The
451 452 .Sy core_content_t
452 453 is a value which describes the various content types of core files.
453 454 These are used in functions such as
454 455 .Xr Pcontent 3PROC
455 456 and
456 457 .Xr Pgcore 3PROC
457 458 to describe and control the types of content that get included. Various
458 459 content types may be included together through a bitwise-inclusive-OR.
459 460 The default system core contents are controlled with the
460 461 .Xr coreadm 1M
461 462 tool. The following table lists the current set of core contents in the
462 463 system, though the set may increase over time. The string after the
463 464 macro is the human readable string that corresponds with the constant
464 465 and is used by
465 466 .Xr coreadm 1M ,
466 467 .Xr proc_content2str 3PROC ,

549 550 structure is used with the
550 551 .Fn Pfdinfo_iter
551 552 function which describes information about a file descriptor. The

575 576 defined in
576 577 .Xr stat 2 .
577 578 The member
578 579 .Sy pr_fd

599 600 and
600 601 .Sy pr_minor
601 602 members contain the major and minor numbers of the device containing the

603 604 .Sy st_dev
604 605 member of the
605 606 .Sy stat
606 607 structure, except that it is broken out into its major and minor components.
607 608 The
608 609 .Sy pr_rmajor
609 610 and
610 611 .Sy pr_rminor
611 612 members are similar in spirit to
612 613 .Sy pr_major
613 614 and
614 615 .Sy pr_minor ;
615 616 however, they are equivalent to the
616 617 .Sy st_rdev
617 618 member of the
618 619 .Sy stat
619 620 structure and thus have meaning for special character and block files.
620 621 .Pp
621 622 The
622 623 .Sy pr_offset
623 624 member contains the current seek offset of the file descriptor. The
624 625 .Sy pr_fileflags
625 626 and
626 627 .Sy pr_fdflags
627 628 members contain the flags that would have been returned by a call to

641 642 .Fn Pxlookup_by_addr ,
642 643 and
643 644 .Fn Pxlookup_by_addr_resolved
644 645 which describes additional information about a symbol.
645 646 The structure is defined as follows:
646 647 .Bd -literal

655 656 .Pp
656 657 The member
657 658 .Sy prs_object
658 659 points to a string that contains the name of the object file, if known,
659 660 that the symbol comes from. The member
660 661 .Sy prs_name
661 662 points to the name of the symbol, if known. This may be unknown due to a
662 663 stripped binary that contains no symbol table. The member
663 664 .Sy prs_lmid
664 665 indicates the link map identifier that the symbol was found on. For more
665 666 information on link map identifiers refer to the
666 667 .Em Linker and Libraries Guide
667 668 and
668 669 .Xr dlopen 3C .

670 671 The members
671 672 .Sy prs_id
672 673 and
673 674 .Sy prs_table
674 675 can be used to determine both the symbol table that the entry came from
675 676 and which entry in the table it corresponds to. If the value of
676 677 .Sy prs_table
677 678 is
678 679 .Dv PR_SYMTAB
679 680 then it came from the ELF standard symbol table. However, if it is instead
680 681 .Dv PR_DYNSYM ,
681 682 then that indicates that it comes from the process's dynamic section.

896 897 is a function pointer type that is used with the
897 898 .Fn Pfdinfo_iter
898 899 function. It is defined as
899 900 .Sy typedef
900 901 .Ft int
901 902 .Fo proc_fdinfo_f
902 903 .Fa "void *"
903 904 .Fa "prfdinfo_t *"
904 905 .Fc .
905 906 The first argument is a pointer to an argument that the user specifies.
906 907 The second argument contains information about an open file descriptor.
907 908 The members of the
908 909 .Sy prfdinfo_t
909 910 are defined earlier in this section. For additional information on using
910 911 this type, see
911 912 .Xr Pfdinfo_iter 3PROC .
912 913 .Sh PROGRAMMING NOTES
913 914 When working with live processes, whether from the
914 915 .Xr Pgrab
915 916 or
916 917 .Xr Pcreate
917 918 family of functions, there are some additional considerations.
918 919 Importantly, if a process calls any of the
919 920 .Xr exec 2
920 921 suite of functions, much of the state information that is obtained,
921 922 particularly that about mappings in the process will be invalid. Callers
922 923 must ensure that they call
923 924 .Xr Preset_maps 3PROC
924 925 when they hold a process handle across an exec. In addition, users of
925 926 the library should familiarize themselves with the
926 927 .Sy PROGRAMMING NOTES
927 928 section of the
928 929 .Xr proc 4
929 930 manual page, which discusses issues of privileges and security.
930 931 .Sh DEBUGGING
931 932 The library provides a means for obtaining additional debugging
932 933 information. The output itself is not part of the
933 934 .Nm
934 935 library's stable interface. Setting the environment variable
935 936 .Ev LIBPROC_DEBUG
936 937 to some value will print information to standard error. For example,
937 938 .Ev LIBPROC_DEUBG Ns = Ns Em please .
938 939 .Sh LOCKING
939 940 Most functions operate on a handle to a process in the form of a
940 941 .Vt "struct ps_prochandle *" .
941 942 Unless otherwise indicated, the library does not provide any
942 943 synchronization for different routines that are operating on the
943 944 .Sy same
944 945 .Nm
945 946 library handle. It is up to the caller to ensure that only a single
946 947 thread is using a handle at any given time. Multiple threads may call
947 948 .Nm
948 949 library routines at the same time as long as each thread is using a
949 950 different handle.
950 951 .Pp
951 952 Each individual function notes its
952 953 .Sy MT-Level
953 954 section. The MT-Level of a routine that matches the above description
954 955 will refer to this manual page. If it does not, then it refers to the
955 956 standard attributes in
956 957 .Xr attributes 5 .
957 958 .Sh INTERFACE STABILITY
958 959 .Sy Uncommitted
959 960 .Pp
960 961 While the library is considered an uncommitted interface, and is still
961 962 evolving, changes that break compatibility have been uncommon and this
962 963 trend is expected to continue. It is documented to allow consumers,
963 964 whether part of illumos or outside of it, to understand the libarary and
964 965 make use of it with the understanding that changes may occur which break
965 966 both source and binary compatibility.
