| | | | | | | | | | | | | | | | | | | | | | * hurd/intr-msg.c: Use INTR_MSG_TRAP macro from machine-dependent "intr-msg.h" for special syscall code, instead of i386-specific asm. * hurd/hurdsig.c: Use INTR_MSG_BACK_OUT macro from machine-dependent "intr-msg.h" before mutating thread state to skip RPC. * sysdeps/mach/hurd/i386/trampoline.c: If PC is inside _hurd_intr_rpc_mach_msg special syscall code, use real SP saved in %ecx. * Makeconfig (link-libc): New variable; use shared library if available. (+link): Use it. * sysdeps/mach/hurd/fork.c (_hurd_fork_locks): Variable removed. Instead, declare with `symbol_set_declare'. (fork): Use symbol_set_* macros for _hurd_fork_locks. Use SS->thread instead of __mach_thread_self (). Suspend all other threads during task_create and port copying.

(_hurdsig_rcv_interrupted_p): Function removed. * sysdeps/mach/hurd/alpha/trampoline.c: Likewise. * sysdeps/mach/hurd/hppa/trampoline.c: Likewise. * sysdeps/mach/hurd/mips/trampoline.c: Likewise. * hurd/intr-msg.c: New file. * hurd/hurd/signal.h (struct hurd_sigstate): New member `cancel'. (_hurdsig_rcv_interrupted_p): Declaration removed. (HURD_EINTR_RPC): Macro removed. (_hurd_longjmp_thread_state, _hurd_interrupted_rpc_timeout): Declare these. * hurd/intr-rpc.h: New file. * hurd/intr-rpc.defs: Just import intr-rpc.h. * hurd/hurdsig.c (_hurd_interrupted_rpc_timeout): New variable. (interrupted_reply_port_location): Take new flag arg; only catch faults if it's set. (abort_rpcs): Rename to _hurdsig_abort_rpcs; take same new flag arg. No longer use _hurdsig_rcv_interrupted_p; instead compare PC to &_hurd_intr_rpc_msg_in_trap. If before it, mutate state to simulate MACH_SEND_INTERRUPTED return; on it, interrupt the operation. All callers changed. * hurd/hurd.h (hurd_thread_cancel, hurd_check_cancel): Declare these. * hurd/Makefile (distribute): Remove intr-rpc.awk. (sig): Add thread-cancel. (transform-user-stub, transform-user-stub-output): Variables removed. * sysdeps/mach/hurd/dl-sysdep.c: Change all RPCs from `__hurd_intr_rpc_*' to `__*'. (_hurd_intr_rpc_mach_msg): New function. (_hurd_thread_sigstate): Function removed. * sysdeps/mach/hurd/ioctl.c: Use _hurd_intr_rpc_mach_msg function, instead of __mach_msg inside HURD_EINTR_RPC macro. * sysdeps/generic/morecore.c [__GNU_LIBRARY__]: Declare `__sbrk' to take ptrdiff_t arg. * sysdeps/mach/hurd/fork.c: Remove _hurd_longjmp_thread_state decl. * sysdeps/mach/hurd/kill.c (kill_pid): Don't make `inline'. * libc-symbols.h [GCC >= 2.7] (strong_alias, weak_symbol, weak_alias): Use `extern' storage class.

| | | | | | | | | | | | * hurd/hurdsig.c (_hurd_internal_post_signal): Don't loop to check pending signals if the thread is in a critical section. It will send us a msg when it finishes. * sysdeps/mach/hurd/pathconf.c: New file. * sysdeps/mach/hurd/fpathconf.c: New file. * sysdeps/mach/hurd/sigaction.c: Only notify the proc server for SIGCHLD when the SA_NOCLDSTOP bit actually changes.

| | | | | | | | | | | | | | | | | | | | | | * Makeconfig (+gccwarn): Add -Winline. * hurd/hurdsig.c (_hurd_internal_post_signal): If SS->context is set, avoid abort_rpcs, and use reply and intr ports saved in SS->context. * sysdeps/mach/hurd/i386/trampoline.c: Don't set SS->intr_port from SS->context. Don't clear SS->context. * sysdeps/mach/hurd/i386/sigreturn.c: Don't set SS->intr_port when setting SS->context. If msg_sig_post returns, re-lock and clear SS->context.
