265141b Fix Bug#22814
Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.
(alloc_unexec_pre, alloc_unexec_post) [HYBRID_MALLOC]:
Set and clear bss_sbrk_did_unexec, on all platforms not just Cygwin.
* src/lisp.h (alloc_unexec_pre, alloc_unexec_post) [!DOUG_LEA_MALLOC]:
Declare unconditionally.
* src/unexcw.c, src/unexelf.c (bss_sbrk_did_unexec): Remove decl.
(unexec): Don’t set or clear bss_sbrk_did_unexec;
the caller now does this.
(Bug#22086)
This ports the recent unexelf.c changes to Fedora x86-64
when configured with GCC’s -fsanitize=undefined option.
* src/unexelf.c (unexec): Align new_data2_size to a multiple
of ElfW (Shdr)’s alignment, so that NEW_SECTION_H returns a
pointer aligned appropriately for its type.
Reuse the .bss section instead, making it SHT_PROGBITS. This way we
don't need to mess with symbol st_shndx, or section sh_link and
sh_info.
This does lead to eu-elflint complaints about symbols defined in .bss
with a needed version, because normally it is undefined symbols that
have needed versions; Defined symbols have version definitions.
The exception is symbols defined by the linker in .dynbss for
variables copied from a shared library in order to avoid text
relocations, with copy relocs to copy their initial values from the
shared library. These symbols are both defined and have needed
versions, and eu-elflink only expects to see them in SHT_NOBITS
sections. Of course there is no real problem with having such symbols
in SHT_PROGBITS sections. glibc ld.so handles them fine.
* unexelf.c: Delete outdated comments.
(PATCH_INDEX): Delete.
(find_section): Delete.
(unexec): Don't add a new section. Instead reuse the last bss
section, extending it to cover dumped data. Make bss sections
SHT_PROGBITS. Remove all patching of sh_link, sh_info and
st_shndx. Rename bss sections.
This rewrites bss handling in the ELF unexec code. Finding bss
sections by name results in complicated code that
- does not account for all names of possible bss sections,
- assumes specific ordering of bss sections,
- can wrongly choose a SHT_NOBITS section not in the bss segment,
- incorrectly calculates bss size (no accounting for alignment gaps),
- assumes .data and .bss are in the same segment.
All of these problems and more are solved by finding the bss segment
in PT_LOAD headers, ie. the address range included in p_memsz but not
p_filesz of the last PT_LOAD header, then matching SHT_NOBITS sections
in that address range.
* unexelf.c: Delete old ppc comment.
(OLD_PROGRAM_H): Define.
(round_up): Delete.
(unexec): Don't search for bss style sections by name. Instead,
use the last PT_LOAD header address range covered by p_memsz
but not p_filesz and match any SHT_NOBITS section in that
address range. Simplify initialisation of section header vars.
Don't assume that section headers are above bss segment. Move
copying of bss area out of section loop. Align .data2 section
to 1, since it now covers the entire bss area. For SHT_NOBITS
sections in the bss segment, leave sh_addr and sh_addralign
unchanged, but correct sh_offset. Clear memory corresponding
to SHT_NOBITS .plt section. Delete comment and hacks for
sections partly overlapping bss range now that the full range
is properly calculated. Delete now dead .sbss code.
(Bug#20614)
This code assumed that there was only one bss section. Rather than
checking for a particular index, check the section type. Also, handle
the possibility that the section was SHT_NOBITS originally and is
unchanged, in which case no clearing is needed (and sh_offset isn't
necessarily valid, which can lead to a wild memset).
* unexelf.c (unexec): Properly handle _OBJC_ symbols in bss sections.
No st_shndx value larger than SHN_LORESERVE should be changed.
* unexelf.c (unexec): Don't adjust any st_shndx larger than
SHN_LORESERVE. Error on SHN_XINDEX.
* unexelf.c (unexec): Merge Alpha and MIPS COFF debug handling.
Don't find .mdebug section index, find the section in the loop.
Allow for unlikely possibility that .mdebug is located at sh_offset
before bss segment, by calculating move from difference in
sh_offset rather than just assuming new_data2_size. Simplify
cbLineOffset handling.
Separate out some of the more mechanical changes so following patches
are smaller.
* unexelf.c (unexec): Rearrange initialisation of program
header vars. Use pointer vars in loops rather than indexing
section header array via macros. Simplify _OBJC_ sym code
and reloc handling code.
First a small fix. The code incorrectly uses "NEW_SECTION_H (n)" when
it should have been using "NEW_SECTION_H (nn)" to find the name of the
section currently being processed. Of course, before the bss
sections, n and nn have the same value, so this doesn't matter except
in the case of .sbss. For .sbss this probably meant .bss (most likely
the next section) was copied from memory. A later patch removes the
bogus .sbss handling anyway.
* unexelf.c (unexec): Use correct index to look up names.
* unexaix.c, unexcoff.c, unexelf.c, unexmacosx.c:
Don't include <sys/stat.h> when no longer needed.
(unexec): Create file with correct mode in the first place,
rather than overwriting the mode later and fiddling with the
global umask in the mean time. Avoid bogus usage like
'umask (777)', which should have been 'umask (0777)'.
(mark_x): Remove. All callers removed.
* configure.ac (PTY_TTY_NAME_SPRINTF): Use emacs_close, not close.
* src/callproc.c (Fcall_process_region):
* src/dired.c (open_directory):
* src/emacs.c (main, Fdaemon_initialized):
* src/image.c (x_find_image_file):
* src/inotify.c (Finotify_rm_watch):
* src/lread.c (Flocate_file_internal):
* src/process.c (Fnetwork_interface_list, Fnetwork_interface_info):
* src/term.c (term_mouse_moveto, init_tty):
* src/termcap.c (tgetent):
* src/unexaix.c, src/unexcoff.c (report_error, report_error_1, adjust_lnnoptrs)
* src/unexaix.c, src/unexcoff.c, src/unexcw.c, src/unexelf.c (unexec):
* src/unexhp9k800.c, src/unexmacosx.c (unexec):
* src/callproc.c (Fcall_process_region):
Use emacs_close, not close.
* src/sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
New macro and function, which emulates the POSIX_CLOSE_RESTART macro
and posix_close function on current platforms (which all lack them).
(emacs_close): Use it. This should fix the races on GNU/Linux and
on AIX and on future platforms that support POSIX_CLOSE_RESTART,
and it should avoid closing random victim file descriptors on
other platforms.
(entry_address, find_section, unexec): Use ptrdiff_t, not int,
when dealing with ElfW (Half) values, since they can exceed 2**31
on 64-bit OpenBSD hosts. Problem reported privately by Han Boetes.
(entry_address): Omit unused NUM arg. All uses changed.
Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
Verify that ElfW (Half) fits in int.
(fatal): Use same signature as lisp.h.
(UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
configure and build with -DUNEXELF_DEBUG without worrying about
other modules that use DEBUG.
(DEBUG_LOG) [UNEXELF_DEBUG]: New macro. All debug code that prints
possibly-wide integers now uses it instead of plain fprintf.
(entry_address): New function, which avoids problems with 32-bit
overflow on 64-bit hosts.
(OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
(round_up): Don't assume the remainder fits in int.
(find_section): Use bool for boolean. Simplify debug code.
(unexec): Don't assume file sizes fit in int or size_t.
Omit unnecessary trailing newline in 'fatal' format.
Use strerror rather than outputting decimal error number.
Remove unused code when emacs is not defined;
this file relies on Emacs now.
Don't assume e_phnum and e_shnum are positive.
* frame.c (Fmouse_position, Fmouse_pixel_position):
* xdisp.c (produce_stretch_glyph):
Declare local vars only when they're needed.
This is clearer and avoids a warning on OpenBSD about unused vars.
* frame.h (FRAME_WINDOW_P): Always evaluate its argument.
This is safer, and avoids OpenBSD warnings about unused vars.
* keyboard.c (record_menu_key): Remove unnecessary decl.
(poll_timer): Define only if POLL_FOR_INPUT is defined.
* unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
as our definition clashes with OpenBSD's.
* xfaces.c (load_face_colors, check_lface_attrs)
(get_lface_attributes_no_remap, get_lface_attributes)
(lface_fully_specified_p, x_supports_face_attributes_p)
(tty_supports_face_attributes_p, face_fontset, realize_face)
(realize_x_face, realize_tty_face):
Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
merely Lisp_Object *. This is more informative and avoids
a warning on OpenBSD about accessing beyond an object's size.
* unexelf.c (unexec) [NS_IMPL_GNUSTEP]: Take account of the case
that where the value of an _OBJC_* symbol points to is in the .bss
section (Bug#10240).
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.
The third one is never used, and the last two are always passed as zero.
* src/emacs.c (unexec): Add declaration.
(Fdump_emacs): Only pass the first two arguments to unexec.
Simplify #ifdef.
* src/unexw32.c (unexec):
* src/unexsol.c (unexec):
* src/unexhp9k800.c (unexec):
* src/unexcw.c (unexec): Remove the last 3 arguments, unused.
* src/unexelf.c (unexec): Remove the last 3 arguments, unused.
(find_section): Use const.
* src/unexmacosx.c (unexec): Remove the last 3 arguments, unused.
(unexec_error): Declare it NO_RETURN.
* src/unexcoff.c (make_hdr): Assume bss_start is always zero, remove
it as an argument, remove data_start and entry_address arguments, unused.
(unexec): Remove bss_start, data_start and
entry_address arguments.
* src/unexaix.c (make_hdr): Assume bss_start is always zero, remove
it as an argument, remove data_start and entry_address arguments, unused.
(unexec): Remove bss_start, data_start and
entry_address arguments.
