Change 'data' argument to fo_ioctl and fo_fcntl from 'caddr_t' to 'void *'.

Match IOHIDSystem and IOFramebuffer request in the IOKit and handle them in

Darwin specific files. The handler does nothing yet.
This needs some improvement. Darwin attaches an IOHIDSystem device to
each human-interface device in the tree: mouse, keyboard, and a few others.
For now we only emulate one IOHIDSystem device.

- WindowServer wants io_master_port? Give it a port!
...
- introduce mach_port_destroy (badly emulated for now)
- on fork/exec, don't set l_private, as the process might be not mature
enough to survive a proc_representative_lwp call (-> kernel panic)
Once we give WindowServer the io_master_port, it sends a message to it:

FIxed the way rights are recycled: the refcount makes only sense for
...
send, send once, and dead names, not for port sets and receive rights.
This make vi and telnet able to work again.
Also removed the all process right list and its lock, which got useless. The
all process lock is replaced by a per process lock, located in struct
mach_emuldata.
Also one bug fix: we did not correctly called Mach hooks for struct emuldata
initialization and release for Darwin processes.

Several things:
...
1) rights should be shared by the threads within a process. While it would
be easier to handle this with the struct proc/struct lwp split, we attempt to
do this now by sharing the right lists. Because each right holds a reference
to struct proc, this might cause some problems later.
2) in pthread_exit, really exit the thread. Also reintialize the righ tlist to
make sure we will not destroy the parent's right list
3) rights can hold multiple permissions on a port (ie: send and receive). Fix th
is.
4) first attempt on right carried by messages. We still have to do rights carrie
d in the message body (complex messages).

2002-12-24 12:29:06 +00:00
41bfbd28fe
On Darwin, mach_init is the system bootstrap process. It is responsible
...
for forking the traditional UNIX init(8) and it does the Mach port naming
service. We need mach_init for the naming service, but unfortunately, it
will only act as such if its PID is 1. We introduce a sysctl
(emul.darwin.init_pid) to fool a given process into thinking its PID is 1.
That way we can get mach_init into behaving as the name server.
Typical use:
/sbin/sysctl -w emul.darwin.init_pid=$$ ; exec /emul/darwin/sbin/mach_init

Added support for exchange of Mach messages between processes.
...
This does not buy us new functionnality for now, because we still have to
discover how mach_init (which acts as a name server, enabling processes to
discover each other's ports) is able to receive messages from other processes
(this is a bootstrap problem, and the bootstrap port might be the place to
search).
While we are there:
- removed a lot of debug which is now available using ktrace.
- reworked message handling to avoid mutliple copyin/copyout of the
same data. ktrace of Mach message now uses the in-kernel copy of the
message instead of copying it from userland.
- packed mach trap handlers arguments into a structure to avoid modifying
everything next time we have to add an argument.

We now have the exact stack initial stack layout of Darwin:
...
macho_hdr, argc, *argv, NULL, *envp, NULL, progname, NULL,
*progname, **argv, **envp
Where progname is a pointer to the program name as given in the first
argument to execve(), and macho_hdr a pointer to the Mach-O header at
the beginning of the executable file.

Better immitate Darwin startup stack layout: there is a slot for the program
...
name after envp, and the 0x1000 at the beginning is a pointer to the binary
mach header (we don't emulate this correctly yet).

in mach_sys_map_fd, if the mapping failed because of the requested place
...
is already used, we want to remap to another place. The vmcmd must be
completely rebuild, else things does not work as expected, as the vmcmd has
been modified by the first mapping attempt.
