* For sparc64 and amd64, define *SIZ32 VM constants.
* Add a new function pointer to struct emul, pointing at a function
that will return the default VM map address. The default function
is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS
macro. This gives emulations control over the default map address,
and allows things to be mapped at the right address (in 32bit range)
for COMPAT_NETBSD32.
* Add code to adjust the data and stack limits when a COMPAT_NETBSD32
or COMPAT_SVR4_32 binary is executed.
* Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr
instead (emulations might have set it differently)
* Since this changes struct emul, bump kernel version to 3.99.2
Tested on amd64, compile-tested on sparc64.
a proclist and call the specified function for each of them.
primarily to fix a procfs locking problem, but i think that it's useful for
others as well.
while i'm here, introduce PROCLIST_FOREACH macro, which is similar to
LIST_FOREACH but skips marker entries which are used by proclist_foreach_call.
raised the exception, don't release the lock, this causes a crash (the lock
shall be released by the process that took it). Wakeup the thread instead,
it will release the lock itself.
remote process. This new implementation also passes all the test programs
I've written so far.
- When exceptions come from traps, no UNIX signal should evet be sent.
- Add a lock to ensure a debugger handles only one exception at a time
- Use a structure to hold flavor and behavior in exception ports, instead
of stuffing the two argument into an int.
- Implement new Mach services: thread_suspend, thread_resume and thread_abort
- Implement Darwin's ptrace PT_ATTACHEXC and PT_THUPDATE commands
- Handle NULL second argument correctly in sigprocmask.
- One mistake in the last commit (darwin_tracesig prototype)
exec case, as the emulation already has the ability to intercept that
with the e_proc_exec hook. It is the responsability of the emulation to
take appropriaye action about lwp_emuldata in e_proc_exec.
Patch reviewed by Christos.
Add some methods to IOFramebuffer (DARWIN_IOFBSETBOUNDS,
DARWIN_IOFBSETCURSORVISIBLE) and to IOHIDSystem (DARWIN_IOHIDPOSTEVENT),
all are unimplemented empty shells.
receiver namespace.
While we are there, refactor mach_msg_overwrite by splitting it into
several smaller functions. It had grown too big to be easily maintainable.
