Simplify copyin/copyout/copyinstr/copyoutstr. Fix bug
where the user virtual address was not updated so that
if the user's buffer crossed a segment boundary, the
wrong data could be copied. Localize USER_SR to the
ILP32 version of setusr/unsetusr.
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).
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.
If NULL is given, then the regular systam call table for the process is used.
- In case of ailure in the child, kill the child and wakeup the parent
- Do call child_return
- The src and dst args were mixed up when copying regs 0-31 to the trapframe
This makes pthread_create(3) fully working (test program works).
mach_port_move_member, mach_port_set_attributes, mach_task_set_special_port,
(none do anything)
Added mach_thread_create_running, which creates a new Mach thread. It
provides the register context of the new thread. We use it in a child
function provided to fork1(). The child function is machine dependent and
is not yet implemented for i386.
The new thread crashes quickly, but at least it starts.
two ways:
- the child gets its pid as retval[0] (userland stub will turn it into a 0),
retval[1] is 1 and it is 0 in the parent.
- in the child, the fork syscall is successful, hence we must skip the next
instruction.
compat/common, so that they can be shared by several emulations, and use
them for Darwin.
This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN
