| | | | | | | | | | | | | | * admin/admin.el (set-version): Update AC_INIT expansion in exec/configure.ac. * exec/configure.ac: Update version to 30.0.90.
* | Optimize process execution on AndroidPo Lu2024-07-011-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * exec/configure.ac (REENTRANT): Remove option for reentrancy. (PROGRAM_COUNTER, HAVE_SECCOMP): Define register providing the program counter and enable seccomp if its headers are available. * exec/exec.c (write_load_command): Avoid defining unused variable. (exec_0): Remove code specific to REENTRANT configurations. * exec/exec.h (struct exec_tracee) <exec_data, data_size>: New fields for loader instructions and their size. * exec/exec1.c (main): Call exec_init before forking. * exec/mipsel-user.h (ELF_NGREG): Delete definition. (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.
* | Disable preprocessing of assembler files with m4 on non-MIPS systemsPo Lu2024-06-271-1/+4
|/ | | | | | | | | | | | | * exec/Makefile.in (is_mips): New substitution. (.s.o): Avoid calling m4 unless it be set. * exec/configure.ac: Substitute is_mips, and don't generate config-mips.m4 otherwise. * exec/loader-x86.s: * exec/loader-x86_64.s: Use assembler rather than m4-defined comment syntax.

* Intercept calls to `openat' under AndroidPo Lu2024-01-271-1/+12
| | | | | | | | | | | | * exec/configure.ac (OPEN_SYSCALL, OPENAT_SYSCALL): Define new macros. * exec/exec.h (struct exec_tracee): New field `sp'. * exec/trace.c (handle_openat): New function. (process_system_call): If handle_openat executes successfully, save the unmodified stack pointer within the tracee structure to be restored once the system call completes.

* Avoid stpncpyPaul Eggert2023-08-121-2/+2
| | | | | | | | | | | | | 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.
* Update Android portPo Lu2023-05-031-0/+4
| | | | | | | | * exec/config.h.in: Autoheader. * exec/configure.ac: Check for siginfo_t.si_syscall. * exec/trace.c (exec_waitpid): If SIGSYS is received, and caused by seccomp, drop it should the call number be the invalid system call used by Emacs.
* Update Android portPo Lu2023-05-031-1/+12
| | | | | | | | | * exec/config.h.in: Autoheader. * exec/configure.ac: Use system extensions. (HAVE_PROCESS_VM): Define if process_vm_readv and process_vm_writev are available. * exec/trace.c (read_memory, user_copy): Implement in terms of process_vm if possible.
* Update Android portPo Lu2023-05-021-0/+51
| | | | | | | | | | | | | | * exec/config.h.in (__bool_true_false_are_defined): * exec/configure.ac (REENTRANT): New definition. (READLINKAT_SYSCALL, READLINK_SYSCALL): New defines. Set on all hosts. * exec/exec.c (MIN, MAX): Remove redundant declarations. Move to config.h. (exec_0): Copy name of executable into NAME when !REENTRANT. * exec/exec.h (struct exec_tracee): New struct `exec_file'. * exec/trace.c (remove_tracee, handle_exec, handle_readlinkat) (process_system_call, after_fork): Handle readlinkat system calls.
* Port Android port to older Android systemsPo Lu2023-05-021-0/+1
| | | | | | | | | * exec/config.h.in: Autoheader. * exec/configure.ac: Check for declarations of stpcpy and stpncpy. * exec/exec.c (stpcpy, stpncpy): Use replacements if declarations are not present; this happens when a new Android NDK is building for an old version of Android.
* Update Android portPo Lu2023-05-011-1/+1
| | | | | | | | * exec/config.h.in: Update config.h.in. * exec/configure.ac: Check for stpcpy and stpncpy. * exec/exec.c (rpl_stpcpy, rpl_stpncpy): Define replacements when they are not present on the system. (process_program_header): Fill comment.

Check if as supports daddi on mips64. * exec/exec.c (check_interpreter): Fix char signedness bug. * exec/loader-mips64el.s (__start): Use DADDI2 and DADDI3 for two- and 3-operand daddi. * exec/mipsel-user.h: Don't include sgidefs.h. * java/INSTALL: Document that m4 is now required. * src/android.c (android_rewrite_spawn_argv): Add missing NULL.
