+
+ Overflow, signedness and related fixes for images.
+
+ * dispextern.h (struct it.stack[0].u.image.image_id)
+ (struct_it.image_id, struct image.id, struct image_cache.size)
+ (struct image_cache.used, struct image_cache.ref_count):
+ * gtkutil.c (update_frame_tool_bar):
+ * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
+ (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
+ (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
+ * nsmenu.m (update_frame_tool_bar):
+ * xdisp.c (calc_pixel_width_or_height):
+ * xfns.c (image_cache_refcount):
+ Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
+ on typical 64-bit hosts.
+
+ * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
+ (x_bitmap_pixmap, x_create_x_image_and_pixmap):
+ Omit unnecessary casts to int.
+ (parse_image_spec): Check that integers fall into 'int' range
+ when the callers expect that.
+ (image_ascent): Redo ascent calculation to avoid int overflow.
+ (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
+ (lookup_image): Remove unnecessary tests.
+ (xbm_image_p): Locals are now of int, not EMACS_INT,
+ since parse_image_check makes sure they fit into int.
+ (png_load, gif_load, svg_load_image):
+ Prefer int to unsigned where either will do.
+ (tiff_handler): New function, combining the cores of the
+ old tiff_error_handler and tiff_warning_handler. This
+ function is rewritten to use vsnprintf and thereby avoid
+ stack buffer overflows. It uses only the features of vsnprintf
+ that are common to both POSIX and native Microsoft.
+ (tiff_error_handler, tiff_warning_handler): Use it.
+ (tiff_load, gif_load, imagemagick_load_image):
+ Don't assume :index value fits in 'int'.
+ (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
+ (imagemagick_load_image): Check that crop parameters fit into
+ the integer types that MagickCropImage accepts. Don't assume
+ Vimagemagick_render_type has a nonnegative value. Don't assume
+ size_t fits in 'long'.
+ (gs_load): Use printmax_t to print the widest integers possible.
+ Check for integer overflow when computing image height and width.

+
+ Integer signedness and overflow and related fixes. (Bug#9079)
+
+ * bidi.c: Integer size and overflow fixes.
+ (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
+ (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
+ (bidi_cache_find_level_change, bidi_cache_ensure_space)
+ (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
+ (bidi_find_other_level_edge):
+ Use ptrdiff_t instead of EMACS_INT where either will do.
+ This works better on 32-bit hosts configured --with-wide-int.
+ (bidi_cache_ensure_space): Check for size-calculation overflow.
+ Use % rather than repeated addition, for better worst-case speed.
+ Don't set bidi_cache_size until after xrealloc returns, because it
+ might not return.
+ (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
+
+ * alloc.c (__malloc_size_t): Remove.
+ All uses replaced by size_t. See Andreas Schwab's note
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
+
+ * image.c: Improve checking for integer overflow.
+ (check_image_size): Assume that f is nonnull, since
+ it is always nonnull in practice. This is one less thing to
+ worry about when checking for integer overflow later.
+ (x_check_image_size): New function, which checks for integer
+ overflow issues inside X.
+ (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
+ This removes the need for a memory_full check.
+ (xbm_image_p): Rewrite to avoid integer multiplication overflow.
+ (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
+ (xbm_read_bitmap_data): Change locals back to 'int', since
+ their values must fit in 'int'.
+ (xpm_load_image, png_load, tiff_load):
+ Invoke x_create_x_image_and_pixmap earlier,
+ to avoid much needless work if the image is too large.
+ (tiff_load): Treat overly large images as if
+ x_create_x_image_and_pixmap failed, not as malloc failures.
+ (gs_load): Use x_check_image_size.
+
+ * gtkutil.c: Omit integer casts.
+ (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
+ (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
+
+ * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
+
+ * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
+ Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
+ would wrongly return t on a 64-bit host.
+
+ * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
+ The plain *_OVERFLOW macros run afoul of GCC bug 49705
+ <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
+ and therefore cause GCC to emit a bogus diagnostic in some cases.
+
+ * image.c: Integer signedness and overflow and related fixes.
+ This is not an exhaustive set of fixes, but it's time to
+ record what I've got.
+ (lookup_pixel_color, check_image_size): Remove redundant decls.
+ (check_image_size): Don't assume that arbitrary EMACS_INT values
+ fit in 'int', or that arbitrary 'double' values fit in 'int'.
+ (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
+ (tiff_load, imagemagick_load_image):
+ Check for overflow in size calculations.
+ (x_create_x_image_and_pixmap): Remove unnecessary test for
+ xmalloc returning NULL; that can't happen.
+ (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
+ (xpm_color_bucket): Use better integer hashing function.
+ (xpm_cache_color): Don't possibly over-allocate memory.
+ (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
+ (gif_memory_source):
+ Use ptrdiff_t, not int or size_t, to record sizes.
+ (png_load): Don't assume values greater than 2**31 fit in 'int'.
+ (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
+ either works, as we prefer signed integers.
+ (tiff_read_from_memory, tiff_write_from_memory):
+ Return tsize_t, not size_t, since that's what the TIFF API wants.
+ (tiff_read_from_memory): Don't fail simply because the read would
+ go past EOF; instead, return a short read.
+ (tiff_load): Omit no-longer-needed casts.
+ (Fimagemagick_types): Don't assume size fits into 'int'.
+
+ Improve hashing quality when configured --with-wide-int.
+ * fns.c (hash_string): New function, taken from sxhash_string.
+ Do not discard information about ASCII character case; this
+ discarding is no longer needed.
+ (sxhash-string): Use it. Change sig to match it. Caller changed.
+ * lisp.h: Declare it.
+ * lread.c (hash_string): Remove, since we now use fns.c's version.
+ The fns.c version returns a wider integer if --with-wide-int is
+ specified, so this should help the quality of the hashing a bit.
+
+ * emacs.c: Integer overflow minor fix.
+ (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
+ Define only if GNU_LINUX.
+ (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
+
+ * dispnew.c: Integer signedness and overflow fixes.
+ Remove unnecessary forward decls, that were a maintenance hassle.
+ (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
+ All uses changed.
+ (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
+ (scrolling_window): Use ptrdiff_t, not int, for byte count.
+ (prepare_desired_row, line_draw_cost):
+ Use int, not unsigned, where either works.
+ (save_current_matrix, restore_current_matrix):
+ Use ptrdiff_t, not size_t, where either works.
+ (init_display): Check for overflow more accurately, and without
+ relying on undefined behavior.
+
+ * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
+ Remove, replacing with the new symbols in lisp.h. All uses changed.
+ * fileio.c (make_temp_name):
+ * filelock.c (lock_file_1, lock_file):
+ * xdisp.c (message_dolog):
+ Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
+ Use pMd etc. instead.
+ * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
+ replacing the pWIDE etc. symbols removed from editfns.c.
+
+ * keyboard.h (num_input_events): Now uintmax_t.
+ This is (very slightly) less likely to mess up due to wraparound.
+ All uses changed.
+
+ * buffer.c: Integer signedness fixes.
+ (alloc_buffer_text, enlarge_buffer_text):
+ Use ptrdiff_t rather than size_t when either will do, as we prefer
+ signed integers.
* alloc.c: Integer signedness and overflow fixes.
Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
(STDC_HEADERS): Remove obsolete defines.
* sysdep.c: Include limits.h unconditionally.
-2011-07-06 Paul Eggert <eggert@cs.ucla.edu>
-
Assume support for memcmp, memcpy, memmove, memset.
* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
* regex.c (memcmp, memcpy):
* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
(__malloc_safe_bcopy): Remove; no longer needed.
- * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
+ * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
well either way, and we prefer signed to unsigned.
+2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix minor problems found by static checking.
+ * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
+ (elsz): Now a signed constant, not a size_t var. We prefer signed
+ types to unsigned, to avoid integer comparison confusion. Without
+ this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
+ "cannot optimize loop, the loop counter may overflow", a symptom
+ of the confusion.
+ * indent.c (Fvertical_motion): Mark locals as initialized.
+ * xdisp.c (reseat_to_string): Fix pointer signedness issue.
+
+2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
+
+ * data.c (Fcdr, Fcar): Revert the last change, since it didn't
+ really clarify much.
+
+ * search.c (Fre_search_backward): Mention `case-fold-search' in
+ all the re_search_* functions (bug#8138).
+
+ * keyboard.c (Fopen_dribble_file): Document when the file is
+ closed (bug#8056).
+
+2011-07-14 Eli Zaretskii <eliz@gnu.org>
+
+ * bidi.c (bidi_dump_cached_states): Fix format of displaying
+ bidi_cache_idx.
+
+ Support bidi reordering of display and overlay strings.
+ * xdisp.c (compute_display_string_pos)
+ (compute_display_string_end): Accept additional argument STRING.
+ (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
+ (reseat_to_string): Initialize bidi_it->string.s and
+ bidi_it->string.schars.

+ NULL (avoids a crash in bidi_paragraph_init). Initialize
+ itb.string.lstring.
+ (init_iterator): Call bidi_init_it only of a valid
+ buffer position was specified. Initialize paragraph_embedding to
+ L2R.
+ (reseat_to_string): Initialize the bidi iterator.
+ (display_string): If we need to ignore text properties of
+ LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The

+ calculation of the object to scan. Fixes an error when using
+ arrow keys.
+ (next_element_from_buffer): Don't abort when IT_CHARPOS is before
+ base_level_stop; instead, set base_level_stop to BEGV. Fixes
+ crashes in vertical-motion.
+ (next_element_from_buffer): Improve commentary for when
+ the iterator is before prev_stop.
+ (init_iterator): Initialize bidi_p from the default value of
+ bidi-display-reordering, not from buffer-local value. Use the
+ buffer-local value only if initializing for buffer iteration.
+ (handle_invisible_prop): Support invisible properties on strings
+ that are being bidi-reordered.
+ (set_iterator_to_next): Support bidi reordering of C strings and
+ Lisp strings.
+ (next_element_from_string): Support bidi reordering of Lisp
+ strings.
+ (handle_stop_backwards): Support Lisp strings as well.
+ (display_string): Support display of R2L glyph rows. Use
+ IT_STRING_CHARPOS when displaying from a Lisp string.
+ (init_iterator): Don't initialize it->bidi_p for strings
+ here.
+ (reseat_to_string): Initialize it->bidi_p for strings here.

+ next_element_from_c_string.
+ (tool_bar_lines_needed, redisplay_tool_bar)
+ (display_menu_bar): Force left-to-right direction. Add a FIXME
+ comment for making that be controlled by a user option.
+ (push_it, pop_it): Save and restore the state of the

+ (handle_single_display_spec, next_overlay_string)
+ (get_overlay_strings_1, push_display_prop): Set up the bidi
+ iterator for displaying display or overlay strings.
+ (forward_to_next_line_start): Don't use the shortcut if
+ bidi-iterating.
+ (back_to_previous_visible_line_start): If handle_display_prop
+ pushed the iterator stack, restore the internal state of the bidi
+ iterator by calling bidi_pop_it same number of times.
+ (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
+ and we are bidi-iterating, don't decrement the iterator position;
+ instead, set the first_elt flag in the bidi iterator, to produce
+ the same effect.
+ (reseat_1): Remove redundant setting of string_from_display_prop_p.
+ (push_display_prop): xassert that we are iterating a buffer.

+ property. Fix a typo in popping stretch info. Add an assertion
+ for verifying that the iterator position is in sync with the bidi
+ iterator.
+ (handle_single_display_spec, get_overlay_strings_1)
+ (push_display_prop): Fix initialization of paragraph direction for
+ string when that of the parent object is not yet determined.
+ (reseat_1): Call bidi_init_it to resync the bidi

+
+2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
+ The old code sometimes used this field without initializing it.
+
+ * alloc.c (gc_sweep): Don't read past end of array.
+ In theory, the old code could also have corrupted Emacs internals,
+ though it'd be very unlikely.
