25 26 27 28
	* lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
	Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
	hosts with pre-C99 libraries, because pD is wrongly defined to "t".

29
	Improve buffer-overflow checking (Bug#8873).
30 31 32 33 34 35 36 37 38
	* fileio.c (Finsert_file_contents):
	* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
	Remove the old (too-loose) buffer overflow checks.
	They weren't needed, since make_gap checks for buffer overflow.
	* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
	The old code merely checked for Emacs fixnum overflow, and relied
	on undefined (wraparound) behavior.  The new code avoids undefined
	behavior, and also checks for ptrdiff_t and/or size_t overflow.

39
	* editfns.c (Finsert_char): Don't dump core with very negative counts.
40 41
	Tune.  Don't use wider integers than needed.  Don't use alloca.
	Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.

43 44
	* insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

45 46 47 48 49 50
	* insdel.c, lisp.h (buffer_overflow): New function.
	(insert_from_buffer_1, replace_range, replace_range_2):
	* insdel.c (make_gap_larger):
	* editfns.c (Finsert_char):
	* fileio.c (Finsert_file_contents): Use it, to normalize wording.

51 52
	* buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

57 58 59
	* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
	(GET_CCL_RANGE, IN_INT_RANGE): Use it.

60 61 62 63 64
	* fileio.c: Don't assume EMACS_INT fits in off_t.
	(emacs_lseek): New static function.
	(Finsert_file_contents, Fwrite_region): Use it.
	Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

65 66
	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

67 68 69 70 71 72 73 74 75
	* fns.c: Don't overflow int when computing a list length.
	* fns.c (QUIT_COUNT_HEURISTIC): New constant.
	(Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
	truncation on 64-bit hosts.  Check for QUIT every
	QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
	faster and is responsive enough.
	(Flength): Report an error instead of overflowing an integer.
	(Fsafe_length): Return a float if the value is not representable
	as a fixnum.  This shouldn't happen except in contrived situations.
76
	(Fnthcdr, Fsort): Don't assume list length fits in int.
77
	(Fcopy_sequence): Don't assume vector length fits in int.
78

79 80 81 82 83 84 85
	* alloc.c: Check that resized vectors' lengths fit in fixnums.
	(header_size, word_size): New constants.
	(allocate_vectorlike): Don't check size overflow here.
	(allocate_vector): Check it here instead, since this is the only
	caller of allocate_vectorlike that could cause overflow.
	Check that the new vector's length is representable as a fixnum.

86 87 88 89 90 91
	* fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
	The previous code was bogus.  For example, next_almost_prime (32)
	returned 39, which is undesirable as it is a multiple of 3; and
	next_almost_prime (24) returned 25, which is a multiple of 5 so
	why was the code bothering to check for multiples of 7?

92 93
	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

94 95
	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

96 97 98 99
	Variadic C functions now count arguments with ptrdiff_t.
	This partly undoes my 2011-03-30 change, which replaced int with size_t.
	Back then I didn't know that the Emacs coding style prefers signed int.
	Also, in the meantime I found a few more instances where arguments
100 101
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.
102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118
	* lisp.h (struct Lisp_Subr.function.aMANY)
	(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
	Arg counts are now ptrdiff_t, not size_t.
	All variadic functions and their callers changed accordingly.
	(struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
	* bytecode.c (exec_byte_code): Check maxdepth for overflow,
	to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
	* callint.c (Fcall_interactively): Check arg count for overflow,
	to avoid potential buffer overrun.  Use signed char, not 'int',
	for 'varies' array, so that we needn't bother to check its size
	calculation for overflow.
	* editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
	* eval.c (apply_lambda):
	* fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
	(struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
	(mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

119 120
	* callint.c (Fcall_interactively): Don't use index var as event count.

121 122 123
	* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
	* mem-limits.h (SIZE): Remove; no longer used.

124
	* xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

	Remove unnecessary casts.
	* xterm.c (x_term_init):
	* xfns.c (x_set_border_pixel):
	* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
	These aren't needed now that we assume ANSI C.

132 133 134 135
	* sound.c (Fplay_sound_internal): Remove cast to unsigned long.
	It's more likely to cause problems (due to unsigned overflow)
	than to cure them.

136 137
	* dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

138 139
	* unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

140 141
	* xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

142 143
	* keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

144 145
	* lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

146 147
	* lread.c (Fload): Don't compare a possibly-garbage time_t value.

	* xdisp.c (get_next_display_element, next_element_from_display_vector):
	Don't assume EMACS_INT fits in int.
153

154 155 156
	* character.h (CHAR_VALID_P): Remove unused parameter.
	* fontset.c, lisp.h, xdisp.c: All uses changed.

157 158
	* editfns.c (Ftranslate_region_internal): Omit redundant test.

159 160 161 162 163 164
	* fns.c (concat): Minor tuning based on overflow analysis.
	This doesn't fix any bugs.  Use int to hold character, instead
	of constantly refetching from Emacs object.  Use XFASTINT, not
	XINT, for value known to be a character.  Don't bother comparing
	a single byte to 0400, as it's always less.

165
	* floatfns.c (Fexpt):
166 167
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

168 169 170
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

171 172
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

173 174 175 176 177
	* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
	Without this fix, on a 64-bit host (aset S 0 4294967386) would
	incorrectly succeed when S was a string, because 4294967386 was
	truncated before it was used.

178 179 180 181
	* chartab.c (Fchar_table_range): Use CHARACTERP to check range.
	Otherwise, an out-of-range integer could cause undefined behavior
	on a 64-bit host.

182 183 184 185 186 187
	* composite.c: Use int, not EMACS_INT, for characters.
	(fill_gstring_body, composition_compute_stop_pos): Use int, not
	EMACS_INT, for values that are known to be in character range.
	This doesn't fix any bugs but is the usual style inside Emacs and
	may generate better code on 32-bit machines.

188 189 190 191 192 193 194 195
	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.
	* charset.c (Fencode_char): Check that character arg is actually
	a character.  Pass an int to ENCODE_CHAR.
	* charset.h (ENCODE_CHAR): Verify that the character argument is no
	wider than 'int', as a compile-time check to prevent future regressions
	in this area.

196
	* character.c (char_string): Remove unnecessary casts.
197 198 199 200 201 202 203 204 205 206

	Make sure a 64-bit char is never passed to CHAR_STRING.
	Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
	by silently ignoring the top 32 bits, allowing some values
	that were far too large to be valid characters.
	* character.h: Include <verify.h>.
	(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
	arguments are no wider than unsigned, as a compile-time check
	to prevent future regressions in this area.
	* data.c (Faset):

208 209 210 211 212 213 214 215 216
	(Fsubst_char_in_region):
	* fns.c (concat):
	* xdisp.c (decode_mode_spec_coding):
	Adjust to CHAR_STRING's new requirement.
	* editfns.c (Finsert_char, Fsubst_char_in_region):
	* fns.c (concat): Check that character args are actually
	characters.  Without this test, these functions did the wrong
	thing with wildly out-of-range values on 64-bit hosts.

217 218 219 220 221
	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
	These casts should not be needed on 32-bit hosts, either.
	* keyboard.c (read_char):
	* lread.c (Fload): Remove casts to unsigned.

222 223 224 225
	* lisp.h (UNSIGNED_CMP): New macro.
	This fixes comparison bugs on 64-bit hosts.
	(ASCII_CHAR_P): Use it.

226
	* character.h (ASCII_BYTE_P, CHAR_VALID_P)

	(SINGLE_BYTE_CHAR_P, CHAR_STRING):
	* composite.h (COMPOSITION_ENCODE_RULE_VALID):
	* dispextern.h (FACE_FROM_ID):
	* keyboard.c (read_char): Use UNSIGNED_CMP.

232 233 234
	* xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
	not to EMACS_INT, to avoid GCC warning.

235 236
	* xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

237 238 239
	* buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
	The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
	isn't needed on 32-bit machines.

247 248
	* window.c (window_body_lines): Now static.

249 250
	* image.c (gif_load): Rename local to avoid shadowing.

251 252 253 254 255 256 257 258
	* lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
	(struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
	* alloc.c (make_save_value): Integer argument is now of type
	ptrdiff_t, not int.
	(mark_object): Use ptrdiff_t, not int.
	* lisp.h (pD): New macro.
	* print.c (print_object): Use it.

262 263
	(total_free_floats, total_floats, total_free_intervals)
	(total_intervals, total_strings, total_free_strings):
264 265 266 267
	Now EMACS_INT, not int.  All uses changed.
	(Fgarbage_collect): Compute overall total using a double, so that
	integer overflow is less likely to be a problem.  Check for overflow
	when converting back to an integer.
268 269 270 271
	(n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
	(n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
	These were 'int' variables that could overflow on 64-bit hosts;
	they were never used, so remove them instead of repairing them.
272
	(nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
273 274 275
	(inhibit_garbage_collection): Set gc_cons_threshold to max value.
	Previously, this ceilinged at INT_MAX, but that doesn't work on
	64-bit machines.
276
	(allocate_pseudovector): Don't use EMACS_INT when int would do.
277

278
	* alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
279
	(allocate_vectorlike): Check for ptrdiff_t overflow.
280 281 282
	(mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
	when a (possibly-narrower) signed value would do just as well.
	We prefer using signed arithmetic, to avoid comparison confusion.
283

284 285 286 287 288 289 290 291 292 293
	* alloc.c: Catch some string size overflows that we were missing.
	(XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
	for convenience in STRING_BYTES_MAX.
	(STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
	The definition here is exact; the one in lisp.h was approximate.
	(allocate_string_data): Check for string overflow.  This catches
	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min
	(PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
	and ptrdiff_t and EMACS_INT are both 64 bits.
294

295 296 297 298
	* character.c, coding.c, doprnt.c, editfns.c, eval.c:
	All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
	* lisp.h (STRING_BYTES_BOUND): Renamed from STRING_BYTES_MAX.

299 300
	* character.c (string_escape_byte8): Fix nbytes/nchars typo.

	and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
	flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
	formatting out-of-range floating point numbers with int
	formats. (Bug#8668)

1173 1174
	* lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

	* data.c: Avoid integer truncation in expressions involving floats.
	* data.c: Include <intprops.h>.
	(arith_driver): When there's an integer overflow in an expression
	involving floating point, convert the integers to floating point
	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
	Do not rely on undefined behavior after integer overflow.

1184 1185
	merge count_size_as_multibyte, parse_str_to_multibyte
	* character.c, character.h (count_size_as_multibyte):

1187 1188 1189 1190 1191 1192
	Check for integer overflow.
	* insdel.c, lisp.h (count_size_as_multibyte): Remove,
	since it's now a duplicate of the other.  This is more of

1374 1375
	Fix some integer overflow issues, such as string length overflow.

1376 1377
	* insdel.c (count_size_as_multibyte): Check for string overflow.

1378 1379 1380 1381 1382 1383 1384 1385 1386
	* character.c (lisp_string_width): Check for string overflow.
	Use EMACS_INT, not int, for string indexes and lengths; in
	particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
	the resulting string length overflows an EMACS_INT; instead,
	report a string overflow if no precision given.  When checking for
	precision exhaustion, use a check that cannot possibly have
	integer overflow.  (Bug#8675)
	* character.h (lisp_string_width): Adjust to new signature.

1387 1388 1389 1390 1391 1392
	* alloc.c (string_overflow): New function.
	(Fmake_string): Use it.  This doesn't change behavior, but saves
	a few bytes and will simplify future changes.
	* character.c (string_escape_byte8): Likewise.
	* lisp.h (string_overflow): New decl.

1393 1394 1395
	Fixups, following up to the user-interface timestamp change.
	* nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
	for UI timestamps, instead of unsigned long.
1396 1397
	* msdos.c (mouse_get_pos): Likewise.
	* w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
1398 1399 1400
	* w32gui.h (Time): Define by including "systime.h" rather than by
	declaring it ourselves.  (Bug#8664)

1401 1402 1403
	* dispextern.h (struct image): Don't assume time_t <= unsigned long.
	* image.c (clear_image_cache): Likewise.

1404 1405
	* term.c (term_mouse_position): Don't assume time_t wraparound.

1406 1407
	Be more systematic about user-interface timestamps.
	Before, the code sometimes used 'Time', sometimes 'unsigned long',
1408 1409
	and sometimes 'EMACS_UINT', to represent these timestamps.
	This change causes it to use 'Time' uniformly, as that's what X uses.
1410 1411 1412 1413 1414 1415 1416 1417 1418 1419 1420 1421 1422 1423 1424 1425 1426 1427 1428
	This makes the code easier to follow, and makes it easier to catch
	integer overflow bugs such as Bug#8664.
	* frame.c (Fmouse_position, Fmouse_pixel_position):
	Use Time, not unsigned long, for user-interface timestamps.
	* keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
	(button_down_time, make_lispy_position, make_lispy_movement): Likewise.
	* keyboard.h (last_event_timestamp): Likewise.
	* menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.

	* term.c (term_mouse_position): Likewise.
	* termhooks.h (struct input_event.timestamp): Likewise.
	(struct terminal.mouse_position_hook): Likewise.
	* xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
	* xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
	* systime.h (Time): New decl.  Pull it in from <X11/X.h> if
	HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
	what it was before.
	* menu.h, termhooks.h: Include "systime.h", for Time.

1429 1430 1431 1432 1433 1434 1435
	* keyboard.c (make_lispy_event): Fix problem in integer overflow.
	Don't assume that the difference between two unsigned long values
	can fit into an integer.  At this point, we know button_down_time
	<= event->timestamp, so the difference must be nonnegative, so
	there's no need to cast the result if double-click-time is
	nonnegative, as it should be; check that it's nonnegative, just in
	case.  This bug is triggered when events are more than 2**31 ms
