* * composite.c: Integer overflow fixes.Paul Eggert2011-07-282-9/+28
| | | | (get_composition_id): Check for overflow in glyph length calculations.
* * coding.c: Integer and memory overflow fixes.Paul Eggert2011-07-282-5/+13
| | | | | | (produce_chars): Redo buffer-overflow calculations to avoid unnecessary integer overflow. Check for size overflow. (encode_coding_object): Don't update size until xmalloc succeeds.
* * character.c (Fstring): Check for size-calculation overflow.Paul Eggert2011-07-282-0/+4
|
* * ccl.c: Integer and memory overflow fixes.Paul Eggert2011-07-282-9/+31
| | | | | | (Fccl_execute_on_string): Check for memory overflow. Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do. Redo buffer-overflow calculations to avoid integer overflow.
* * callproc.c (child_setup): Don't assume strlen fits in int.Paul Eggert2011-07-282-1/+5
|
* * buffer.c: Memory overflow fixes.Paul Eggert2011-07-282-12/+14
| | | | | | (overlays_at, overlays_in, record_overlay_string, overlay_strings): Don't update size of array until after memory allocation succeeds, because xmalloc/xrealloc may not return.
* * bidi.c: Integer overflow fix.Paul Eggert2011-07-282-11/+26
| | | | | | (bidi_shelve_header_size): New constant. (bidi_cache_ensure_space, bidi_shelve_cache): Use it. (bidi_cache_ensure_space): Avoid integer overflow when allocating.

| | | | | | | | | | | | * character.c (lisp_string_width): * composite.c (composition_table_size, n_compositions) (get_composition_id, composition_gstring_from_id): * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id): * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): * window.c (Frecenter): Use ptrdiff_t, not int, for composition IDs. * composite.c (get_composition_id): Check for integer overflow. * composite.h: Adjust prototypes to match the above changes.

| | * Port to OpenBSD.Paul Eggert2011-07-194-16/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html and the surrounding thread. * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar rather than fgets, and retry after EINTR. Otherwise, 'emacs --batch -f byte-compile-file' fails on OpenBSD if an inactivity timer goes off. * s/openbsd.h (BROKEN_SIGIO): Define. * unexelf.c (unexec) [__OpenBSD__]: Don't update the .mdebug section of the Alpha COFF symbol table.

| * | * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.Paul Eggert2011-07-182-4/+17
| | | | | | | | | | | | | | | This fixes some race conditions on the permissions of any newly created file.
| * | * alloc.c (valid_pointer_p): Use pipe, not open.Paul Eggert2011-07-182-5/+8
| | | | | | | | | | | | This fixes some permissions issues when debugging.

| * | * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)Paul Eggert2011-07-182-4/+21
| | | | | | | | | | | | | | | | | | If fchown fails to set both uid and gid, try to set just gid, as that is sometimes allowed. Adjust the file's mode to eliminate setuid or setgid bits that are inappropriate if fchown fails.
| * | CC Mode: Fontify declarators properly when, e.g., a jit-lock chunk beginsAlan Mackenzie2011-07-184-4/+69

* | | * charset.c (Fdefine_charset_internal): Check for integer overflow.Paul Eggert2011-07-182-3/+21

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * character.c (Fchar_width, c_string_width, lisp_string_width): * character.h (CHAR_WIDTH): * indent.c (MULTIBYTE_BYTES_WIDTH): Use sanitize_char_width to avoid undefined and/or bad behavior with outlandish widths. * character.h (sanitize_tab_width): Renamed from sanitize_width, now that we have two such functions. All uses changed. (sanitize_char_width): New inline function.
* | | Don't assume that tab-width fits in int.Paul Eggert2011-07-184-20/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | * character.h (sanitize_width): New inline function. (SANE_TAB_WIDTH): New macro. (ASCII_CHAR_WIDTH): Use it. * indent.c (sane_tab_width): Remove. All uses replaced by SANE_TAB_WIDTH (current_buffer). * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
* | | * fileio.c: Integer overflow issues with file modes.Paul Eggert2011-07-182-3/+6
| | | | | | | | | | | | (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

| | | | | | | | | | | | | | | | | | | | | (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed. (x_send_scroll_bar_event): Likewise. Check that the size does not exceed limits imposed by XClientMessageEvent, as well as the usual ptrdiff_t and size_t limits.
* | | * keyboard.c: Overflow, signedness and related fixes.Paul Eggert2011-07-162-10/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (make_lispy_movement): Use same integer type in forward decl that is used in the definition. (read_key_sequence, keyremap_step): Change bufsize argument back to int, undoing my 2011-03-30 change. We prefer signed types, and int is wide enough here. (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string length, not size_t. Use ptrdiff_t for index, not int. (keyremap_step, read_key_sequence): Redo bufsize check to avoid possibility of integer overflow.

| | * * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)Paul Eggert2011-07-162-1/+11
| | | | | | | | | | | | | | | | | | | | | This works around a problem with the previous change to Fcopy_file. Recent glibc declares fchown with __attribute__((warn_unused_result)), and without this change, GCC might complain about discarding fchown's return value.
