* sysdeps/mach/hurd/fork.c: Skip NEWPROC just like NEWTASK when
copying send rights into child. When we hit our name for our proc
port, just copy NEWPROC directly instead of repeating proc_task2proc
to install the child's port.
2001-04-08 Roland McGrath <roland@frob.com>
* Makeconfig ($(common-objpfx)soversions.i): Grok entries with DEFAULT
in second column, to provide default values for third column.
* shlib-versions: Add comments about using DEFAULT in second column.
(s390x-.*-linux.*): Replace individual entries with a DEFAULT entry.
(cris-.*-linux.*): Likewise.
* hurd/hurdsig.c (_hurdsig_init): If __hurd_threadvar_stack_mask is
nonzero, use cthread_fork to create the signal thread.
* hurd/msgportdemux.c (_hurd_msgport_receive): Initialize
_hurd_msgport_thread here (to self).
* sysdeps/mach/hurd/fork.c (__fork): When __hurd_sigthread_stack_end
is zero, instead compute child signal thread's starting SP from parent
signal thread's current SP and the threadvar_stack variables.
* hurd/Versions (GLIBC_2.1.3): Add cthread_fork, cthread_detach.
These are now referenced weakly by _hurdsig_init.
* hurd/report-wait.c (_S_msg_report_wait): Fix typo:
&_hurd_itimer_thread not &_hurd_msgport_thread.
1999-10-01 Roland McGrath <roland@baalperazim.frob.com>

(install_ctty): Do the changing of the cttyid port cell here, inside
the critical section while we holding the dtable lock.
(_hurd_setcttyid, tiocsctty, tiocnotty): Use that instead of changing
the port cell and calling rectty_dtable.
(_hurd_locked_install_cttyid): New function, split out of install_ctty.
(install_ctty): Use it inside a critical section, with the lock held.
* sysdeps/mach/hurd/setsid.c (__setsid): Use
_hurd_locked_install_cttyid to effect the cttyid and dtable changes
after proc_setsid, having held the dtable lock throughout.
* hurd/dtable.c (ctty_new_pgrp): With the dtable lock held, check the
cttyid port for null and bail out early if so. The dtable lock
serializes us after any cttyid change and its associated dtable update.
* sysdeps/mach/hurd/fork.c (__fork): Make use of `insert_type' when
inserting a send right into the child instead of unconditionally
copying the send right.
* hurd/hurd-raise.c (_hurd_raise_signal): Pass sigcode in msg_sig_post

change meaninglessly.
* hurd/hurd/signal.h (struct hurd_sigstate): Replace critical section
flag with a spin lock.
(_hurd_critical_section_lock): Use spin_try_lock on that to see if we
get it. No need to take SS->lock at all.
(_hurd_critical_section_unlock): Unlock SS->critical_section_lock
instead of clearing the old flag member.
* hurd/hurdsig.c (_hurd_internal_post_signal): Use spin_lock_locked to
test the critical section state.

hurd_file_name_path_lookup.

__attribute__ ((__mode__ (__XX__))).
Wed Feb 7 03:24:05 1996 Torbjorn Granlund <tege@tmg.se>
* sysdeps/i386/i586/memcopy.h (WORD_COPY_FWD): Manually allocate
destination cache lines.
(WORD_COPY_BWD): Likewise.

another dir_lookup of "".
* 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.
* hurd/thread-cancel.c: New file.

(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.

-nostdlib.
* sysdeps/mach/hurd/fork.c: Subfunction `unlockss' removed. Lock
_hurd_siglock only around initial task creation in parent. Use
_hurd_critical_section_unlock at end. Handle dead name rights
properly, and deal with a send right dying while we try to copy
it. For the time being, use assert_perror for kernel and proc RPC
failures.
Fri Apr 21 01:10:15 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
