Previously, the section `Inherited Ports' was commented out. This was
done, as the functionality was unused by the Hurd. The functions
`mach_ports_register' and `mach_ports_lookup' were never removed, and
are exposed to user space.
This patch brings the documentation back and adds a remark at the top,
that the section documents the original intentions for this interface.
I chose bringing back the documentation over removing the
functionality because I like to make use of it as a method for service
discovery that is deliberately orthogonal to the way the service
lookup is usually done in the Hurd. This can be used to implement
robust low-level debugging facilities.
* doc/mach.texi: Restore section `Inherited Ports'.
|
|
* ipc/ipc_kmsg.c (ipc_kmsg_copyout_header): If a protected payload is
set for the destination port, provide it in msgh_protected_payload.
* ipc/mach_msg.c (mach_msg_trap): Likewise in the fast paths.
* doc/mach.texi (Message Receive): Document message semantics with
protected payloads.
|
|
* include/mach/message.h: Define MACH_MSG_TYPE_PROTECTED_PAYLOAD.
(MACH_MSG_TYPE_LAST): Adjust accordingly.
* doc/mach.texi (Message Format): Document
MACH_MSG_TYPE_PROTECTED_PAYLOAD.
|
|
* include/mach/message.h (mach_msg_header_t): Add
msgh_protected_payload as a union with msgh_local_port.
* doc/mach.texi (Message Format): Document msgh_protected_payload.
|
|
* include/mach/mach_port.defs: Add mach_port_{set,clear}_protected_payload.
* ipc/mach_port.c: Implement mach_port_{set,clear}_protected_payload.
* doc/mach.texi (Receive Rights): Document
mach_port_{set,clear}_protected_payload.
|
|
* doc/mach.texi (Kernel Debugger Commands): Explain the floating point
flag.
|
|
The number of priorities has been changed from 32 to 50 in
6a234201081156e6d5742e7eeabb68418b518fad.
* doc/mach.texi: Update accordingly.
|
|
* doc/mach.texi (Task Information): Document the new task_set_name
procedure.
|
|
The referenced Invariant sections does not exist, and the front and back
covers do not hold much information.
|
|
* doc/mach.texi: Replace @itemx with @item for --enable-tulip and
--enable-epic100.
|
|
* doc/mach.texi: Add dwatch documentation.
