* | Remove Gnulib explicit_bzero modulePaul Eggert2022-12-182-39/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | It’s no longer needed, as it is now merely a thin layer around C23-style memset_explicit and we might as well just call the C23 standard function; that’s more forward-looking. * admin/merge-gnulib (GNULIB_MODULES): Remove explicit_bzero, and add memset_explicit. * lib/explicit_bzero.c, m4/explicit_bzero.m4: Remove these files, which were copied from Gnulib. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * src/gnutls.c (gnutls_symmetric_aead): Use memset_explicit instead of explicit_bzero.

* Port better to C23 bool+true+false keywordsPaul Eggert2022-09-281-1/+3
| | | | | | | | | | | | | | | | | | | | C23 is adding the C++ keywords bool, true, and false; prefer them to <stdbool.h> if they are available. * admin/merge-gnulib (GNULIB_MODULES): Add stdbool, which emulates C23 on pre-C23 platforms. (AVOIDED_MODULES): Remove stdbool; Gnulib has renamed this module to stdbool-c99 and nobody uses it so it does not need to be avoided. * m4/c-bool.m4: New file, from Gnulib stdbool module. * lib-src/seccomp-filter.c, src/conf_post.h, src/dynlib.h: * src/emacs-module.c, src/nsterm.m, src/systhread.h: * test/src/emacs-module-resources/mod-test.c: Use the C23 style and use bool without including <stdbool.h>. The Gnulib stdbool module causes config.h to include stdbool.h on pre-C23 platforms. * src/emacs-module.h.in: Don’t include <stdbool.h> if C23 or later, or if it has already been included.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent changes to src/verbose.mk.in, it’s more important to be consistent about putting AM_V_GEN and similar macros at the start of a rule’s recipe, since ‘make’ now outputs the diagnostic before it executes the recipe rather than the shell outputting it. Most of the uses were already this way, but there were a few outliers. Problem reported by Pip Cet. * Makefile.in (${srcdir}/info/dir): * admin/unidata/Makefile.in (${unidir}/charprop.el, ${unifiles}) (${unidir}/emoji-labels.el): * lib/Makefile.in (libgnu.a, libegnu.a): * lisp/Makefile.in (TAGS): * src/Makefile.in (lisp.mk, Emacs): * test/Makefile.in (%.log, $(test_module)): Put AM_V_GEN and similar macros first.

* Fix md5 issue in recent Gnulib mergePaul Eggert2021-10-052-1/+152
| | | | | | | | | | | | When configured --with-native-compilation, Emacs needs md5_stream. Problem reported by Andy Moreton (Bug#50985#23). * admin/merge-gnulib (GNULIB_MODULES): Add crypto/md5, needed for --with-native-compilation. (AVOIDED_MODULES): Avoid crypto/af_alg, since Emacs doesn’t need to bother with kernel-supported cryptography algorithms. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate by running admin/merge-gnulib. * lib/md5-stream.c: New file, copied from Gnulib.
* Unbreak the build after Gnulib updateEli Zaretskii2021-10-051-1/+1
| | | | | | | * lib/gnulib.mk.in (GNULIBHEADERS_OVERRIDE_WINT_T): Rename from GNULIB_OVERRIDES_WINT_T. * configure.ac (GNULIBHEADERS_OVERRIDE_WINT_T): Define. (Bug#50985)
* Update from GnulibPaul Eggert2021-10-04174-2725/+3476
| | | | | | | | | | | | | | | | | | Make the following changes by hand, and run 'admin/merge-gnulib'. * .gitignore: Add lib/malloc/*.gl.h. * admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h directly from Gnulib, without worrying about Gnulib modules, as these files are special cases. (AVOIDED_MODULES): Remove malloc-posix. * lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4: * m4/year2038.m4: New files, copied from Gnulib. * lib/malloca.c, lib/malloca.h: * m4/close-stream.m4, m4/glibc21.m4, m4/malloca.m4: Remove. These are either no longer present in Gnulib, or are no longer needed by modules that Emacs uses. * oldXMenu/AddPane.c, oldXmenu/Addsel.c: Include XmenuInt.h first; needed for new Gnulib. * src/xmenu.c: Call emacs_abort, not abort.
* Redo emacsclient socket symlink-attack checkingPaul Eggert2021-07-232-0/+521
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * admin/merge-gnulib (GNULIB_MODULES): Add file-has-acl. * lib/file-has-acl.c: New file, copied from Gnulib. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib-src/emacsclient.c: Include acl.h, for file_has_acl. (O_PATH): Default to O_SEARCH, which is good enough here. (union local_sockaddr): New type. (socket_status): Remove, replacing with ... (connect_socket): New function. All callers changed. This function checks for ownership and permissions issues with the parent directory of the socket file, instead of checking the owner of the socket (which does not help security). (socknamesize): Move to file scope. (local_sockname): New arg S. No need to pass socknamesize. UID arg is now uid_t. All callers changed. Get file descriptor of parent directory of socket, to foil some symlink attacks. Do not follow symlinks to that directory. (set_local_socket): Create the socket here instead of on each attempt to connect it. Fall back from XDG_RUNTIME_DIR to /tmp only if the former fails due to ENOENT. Adjust permission-failure diagnostic to match changed behavior. This addresses Bug#33847, which complained about emacsclient in a safer XDG environment not connecting to an Emacs server running in a less-safe enviroment outside XDG. The patch fixes a longstanding issue with emacsclient permission checking. It’s ineffective to look at the permission of the socket file itself; on some platforms, these permissions are ignored anyway. What matters are the permissions on the parent directory of the socket file, as these are what make symlink attacks possible. Change the permissions check accordingly, and also refuse to follow symlinks to that parent directory. These changes make it OK for emacsclient to fall back from XDG_RUNTIME_DIR to the traditionally less-safe /tmp/emacsNNNN directories, since /tmp is universally sticky nowadays.

* Fix the unexec build on GNU/LinuxEli Zaretskii2021-05-191-1/+3
| | | | | | | | | | | | | The unexec build on GNU/Linux must use HYBRID_MALLOC (gmalloc.c) and sheap.c. This was inadvertently disabled because a configure-time test for 'sbrk' was moved as side effect of an unrelated change. * configure.ac: Test for 'sbrk' before using the result in the decision about SYSTEM_MALLOC and HYBRID_MALLOC. (HYBRID_MALLOC): Prevent Gnulib from redirecting 'free' to its replacement 'rpl_free'. * lib/Makefile.in (not_emacs_OBJECTS): Add mallooc/%.o and free.o.

(clean): Also remove */*.o and $(DEPDIR)/*/*.d, to clean out malloc/*.o and deps/malloc/*.d. Just remove *.d files in dependencies so that rm does not complain about not being able to remove deps/malloc. (extraclean): Also remove malloc, if it is empty.
