| * Add support for Mercury (https://mercurylang.org) in 'etags'Fabrice Nicol2021-06-061-4/+486
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tag declarations starting lines with ':-'. By default, all declarations are tagged. Optionally, first predicate or functions in clauses can be tagged as in Prolog support using '--declarations'. (Bug#47408). * lib-src/etags.c (test_objc_is_mercury, Mercury_functions) (mercury_skip_comment, mercury_decl, mercury_pr): Implement Mercury support. As Mercury and Objective-C have the same file extension .m, a heuristic test tries to detect the language. * doc/man/etags.1: Document the change. Add Mercury-specific behavior for '--declarations'. This option tags first predicates or functions in clauses in addition to declarations.

| * Ensure that argument to 'verify' is a constant expression.Philipp Stephani2021-04-221-1/+2
| | | | | | | | | | | | | | Casting NULL is not a constant expression (Bug#47951). * lib-src/seccomp-filter.c (main): Turn check for null pointer representation into a runtime assertion.
| * Seccomp filter: deal with arch_prctl(ARCH_CET_STATUS, ...).Philipp Stephani2021-04-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dynamic loader of GNU libc 2.28 uses this system call to initialize CPU information, see https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/x86/cpu-features.c;hb=glibc-2.28#l28. Simulating an older kernel by returning EINVAL should be the most harmless rule here. The ARCH_CET_STATUS symbol isn't yet exposed by the kernel headers; see the FIXME at the top of https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/x86/include/asm/prctl.h;hb=glibc-2.28. * lib-src/seccomp-filter.c (ARCH_CET_STATUS): Define if not already present. Inline the value because there doesn't seem to be a header file exporting this constant yet. (main): Make ARCH_CET_STATUS subfunction of arch_prctl return EINVAL.
| * Fix Seccomp filter on CentOS 8.3 (Bug#47828).Philipp Stephani2021-04-181-3/+3

| * Generate Seccomp filters only if we have the necessary constants.Philipp Stephani2021-04-121-0/+3
| | | | | | | | | | | | | | | | | | | | If we're missing SECCOMP_SET_MODE_FILTER, the seccomp-filter build fails. Reuse the existing HAVE_SECCOMP configuration variable, which checks for these macros. * configure.ac (HAVE_SECCOMP): Substitute in Makefile.in. * lib-src/Makefile.in (HAVE_SECCOMP): New variable. (SECCOMP_FILTER): Define only if HAVE_SECCOMP.
| * Add a variant of the Seccomp filter file that allows 'execve'.Philipp Stephani2021-04-112-7/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is useful when starting Emacs with a Seccomp filter enabled, e.g. using 'bwrap'. * lib-src/seccomp-filter.c (main): Generate new Seccomp files. * lib-src/Makefile.in (all) (seccomp-filter.bpf seccomp-filter.pfc seccomp-filter-exec.bpf seccomp-filter-exec.pfc): Generate new Seccomp files. * .gitignore: Ignore new Seccomp files. * test/src/emacs-tests.el (emacs-tests/bwrap/allows-stdout): New unit test.

| | | | | | | | | | | | | | | | Only Linux 4.14 and later contain the required support for SECCOMP_RET_KILL_PROCESS. * lib-src/Makefile.in (SECCOMP_FILTER): Define only if we run at least Linux 4.14.
| * Seccomp filter: allow reading the current time (Bug#47708).Philipp Stephani2021-04-111-0/+7
| | | | | | | | * lib-src/seccomp-filter.c (main): Allow reading the current time.
| * Use pkg-config to check for libseccomp.Philipp Stephani2021-04-111-3/+6
| | | | | | | | | | | | | | | | | | | | We need at list version 2.4.0 of libseccomp for seccomp-filter.c to build cleanly. * configure.ac: Use pkg-config to check for libseccomp. * lib-src/Makefile.in (HAVE_LIBSECCOMP, LIBSECCOMP_LIBS) (LIBSECCOMP_CFLAGS): New variables. (SECCOMP_FILTER, seccomp-filter$(EXEEXT)): Use them.
| * Remove SCMP_FLTATR_CTL_LOG attribute from Seccomp filter.Philipp Stephani2021-04-111-1/+0
| | | | | | | | | | | | | | Whether or not we log failing syscalls isn't security-critical, and we shouldn't care. * lib-src/seccomp-filter.c (main): Remove log attribute.
| * Only attempt to generate seccomp filter files on x86-64 systems.Philipp Stephani2021-04-111-2/+9
| | | | | | | | | | | | | | | | The seccomp filters are always architecture-specific, and seccomp-filter.c right now only supports x86-64. * lib-src/Makefile.in (SECCOMP_FILTER): New variable. (DONT_INSTALL, all, seccomp-filter$(EXEEXT)): Use it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The binary uses the 'seccomp' helper library. The library isn't needed to load the generated Secure Computing filter. * configure.ac: Check for 'seccomp' header and library. * lib-src/seccomp-filter.c: New helper binary to generate a generic Secure Computing filter for GNU/Linux. * lib-src/Makefile.in (DONT_INSTALL): Add 'seccomp-filter' helper binary if possible. (all): Add Secure Computing filter file if possible. (seccomp-filter$(EXEEXT)): Compile helper binary. (seccomp-filter.bpf seccomp-filter.pfc): Generate filter files. * test/src/emacs-tests.el (emacs-tests/seccomp/allows-stdout) (emacs-tests/seccomp/forbids-subprocess): New unit tests. * test/Makefile.in (src/emacs-tests.log): Add dependency on the helper binary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac: Instead of AC_CHECK_HEADER, use AC_COMPILE_IFELSE with X11/Intrinsic.h when checking for X11/extensions/Xrender.h. This suppresses a bogus "report a bug to bug-gnu-emacs" diagnostic from 'configure' in Solaris 10. (SETUP_SLAVE_PTY): Adjust to recent renaming of forkin to std_in in callproc.c. Needed on Solaris and Unixware. * lib-src/Makefile.in (LIB_GETRANDOM, LIBS_ETAGS): New vars, needed because on Solaris 10 the Gnulib tempname module now needs the -lrt library for clock_gettime. Throw in the LIB_GETRANDOM stuff too while we’re at it; from getrandom.m4 it seems to be needed for MingW. (LIBS_MOVE, etags_libs): Use them. * src/callproc.c [SETUP_SLAVE_PTY]: Include sys/stream.h and sys/stropts.h, for SETUP_SLAVE_PTY’s definiens. * src/process.c [NEED_BSDTTY]: Don’t include bsdtty.h; hasn’t been needed in years. [USG5_4]: Don’t include sys/stream.h or sys/stropts.h; these directives havbe been moved to callproc.c because the only use of SETUP_SLAVE_PTY is there now.

No need for realloc (and the old code leaked memory anyway on failure); just use free+malloc.
