(struct mipsel_regs): Reduce number of gregs to 32, but introduce separate fields for special registers. * exec/trace.c (use_seccomp_p): New variable; defile to false if !HAVE_SECCOMP. (remove_tracee): Cease providing for non-reentrant configurations. Release executable data if present. (handle_clone_prepare): Likewise. Resume process with PTRACE_CONT if seccomp-based interception is enabled. (handle_clone, check_signal): Resume processes as above. (handle_exec): Divide into two functions, with only rewriting the system call and generating instructions for the loader remaining in the first, and copying such instructions into the loader's stack removed into a new function, `finish_exec'. (finish_exec): New function. (handle_readlinkat, handle_openat): Abolish non-REENTRANT configurations. (process_system_call): Divide exec system calls into two phases, disambiguated by the value of tracee->waiting_for_syscall. Typo fixes. Accommodate syscall-exit-stops where the signal was initially intercepted by `seccomp_system_call'. (interesting_syscalls): New array. (ARRAYELTS): New macro. (seccomp_system_call, establish_seccomp_filter): New function. (tracing_execve) [HAVE_SECCOMP]: Establish a seccomp filter if this is to be enabled. (after_fork): Provide PTRACE_O_TRACESECCOMP. Resume process with PTRACE_CONT if seccomp-based interception is enabled. (exec_waitpid): Resume process with PTRACE_CONT if seccomp-based interception is enabled. Dispatch stops identifying as PTRACE_EVENT_SECCOMP to `seccomp_system_call'. (exec_init): Establish whether it is possible to enable seccomp.

* Fix autogen.sh’s spurious ‘git diff’ outputPaul Eggert2024-01-203-4222/+0
| | | | | | | | | | | | | | | | Problem reported by Gerd Möllmann (Bug#68464). * .gitignore: Ignore files in exec that are now copied from build-aux. * admin/merge-gnulib (avoided_flags): Instead of clearing autom4te.cache here ... * autogen.sh (do_git): ... clear it here. Use config.guess, config.sub and install-sh from the Emacs repository, as they are more likely to be up to date. This avoids unnecessary differences among different builders, and avoids unnecessary ‘git diff’ output after autogen.sh. Also, copy these files from build-aux to exec since there should be no difference between the two copies. * exec/config.guess, exec/config.sub, exec/install-sh: Remove from repository, as autogen.sh now copies them from build-aux.

* Avoid stpncpyPaul Eggert2023-08-122-74/+7
| | | | | | | | | | | | | It’s not worth the porting hassle, and as the glibc manual says, “this function is generally a poor choice for processing strings”. * admin/merge-gnulib (GNULIB_MODULES): Remove stpncpy. * exec/configure.ac: Do not check for stpncpy. * exec/exec.c (rpl_stpncpy, stpncpy): Remove this replacement. (exec_0): Properly clear buffer1. Use memcpy instead of stpncpy to add the trailing name. This code is clearly still suboptimal but efficiency is not that important here and I tried to minimize the change. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
