fvdl d5aece61d6 Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.
2003-06-29 22:28:00 +00:00
darrenr 960df3c8d1 Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

manu faba943220 Added IOHIDSystem properties (this is about keyboard mapping)
Also added a ssize arg to mach trap args so that trap handler are aware
of the sent packet size.
2003-06-03 06:48:47 +00:00
manu 2e73bb80fe More IOKit basics. Also introduced a mach_port flag to get a precise idea
of what port is sending a message to the kernel.

manu 357afc4e2f Some bits of the first iokit call 2003-02-04 22:47:41 +00:00
manu cb771e3c64 Make the beast build again (but it is still probably broken) 2003-01-24 21:37:01 +00:00
matt b03d17694a Do a preliminary switchover of the mach code to lwp's. It compiles now
but probably doesn't work.   That's for someone who understand this code
better.

manu 80d406d8fe 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.

manu 2c04ce0604 A better implementation of right carried by messages. We now correctly create
the right in the destination process.

This is a small step backward for functionnality: vi does not work anymore
because our right checks cause some spurious errors, but this will be fixed
later.

manu f3e11e72e9 Introduce port names, deallocate mach ressources at Darwin process exit 2002-12-31 15:47:37 +00:00
manu 6f978415df When the kernel transmits a message to a processs, remote and local port
are swapped. Also added some debug.
2002-12-31 13:09:38 +00:00
manu 1d1b901b90 bug fix: in debug functions, the port set right and the port set members
wer mixed up
2002-12-30 19:32:15 +00:00
manu d9f2a8dbcd - When mach_init saves the bootstrap port, make it the default bootstrap port
for any program we will launch later. This is a hack to avoid the need
of launching any Darwin binary as a child of mach_init
- More and more debug
2002-12-30 18:44:33 +00:00
manu 27427542f4 When the right is not a port set, set the port set head to the right
itself. That way when we want to wakeup a receiver, we just have to
wakeup the port set head, it will work either for port set and for non
port sets.
2002-12-30 12:41:52 +00:00
manu 874517b438 - When MACH_MSG_RCV_LARGE is set, we must return a message with just a header
and a body.
- If mach_init is not availabkle for boostrap requests, try to handle them
in the kernel (we don't really handle them, we just try to avoid hanging there)
- minor tweaks.
2002-12-27 19:57:47 +00:00
manu f464631d66 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).

manu 2894c4a53f Handle the kernel clock service by the kernel. 2002-12-26 13:45:17 +00:00
manu f4d5ba5dbd Queue and dequeue message replies from kernel servers. This is less efficient,
but it sticks closer to the actual Mach semantics: the reply is queued at the
end of the queue. Also add more debug messages on port operations.
2002-12-26 11:41:46 +00:00
manu dc403d4519 Bootstrap messages are not for the kernel, they are for mach_init. 2002-12-24 16:40:46 +00:00
manu b2a7ace594 Better error reporting in mach_msg_trap: this system call does not use the
standard error codes.
2002-12-24 15:54:26 +00:00
manu 360f1c3ebe Cosmetic changes, added a debug printf 2002-12-22 21:51:56 +00:00
manu 8958b6f9ba Handle receive operations on port sets 2002-12-21 23:50:47 +00:00
manu 3b71b464b2 First attempt on mach ports sets. Also maitian only one list of rights
per process, as segregating recv, send and send_once did not buy anything.
2002-12-19 22:23:06 +00:00
manu 5ba396cfb3 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.
2002-12-17 18:42:54 +00:00
manu b8a9df5e21 FIrst attempt at mach ports and rights, which are needed if we ever want
to implement messages between kernel and userland.
While we are there, cleanup some debug messages.
2002-12-15 00:40:24 +00:00
manu 6492e2171f Added support for dumping mach messages in ktrace/kdump. While we are
there, KNFify a few functions.
2002-12-09 21:29:20 +00:00
manu 0f239dc026 Check for alternate receive buffer for mach_msg_overwrite_trap
Check for target buffer length, and fail if it is too short
Move mach_msg_trap and mach_msg_overwrite_trap to their own file
Remove some useless debug messages now we have ktrace
Remove __P()
