2015-07-09Allow non-privileged tasks to wire 64KiB task memorySamuel Thibault
* doc/mach.texi (vm_wire): Document that the host port does not have to be privileged. * include/mach/mach_hosts.defs (vm_wire): Use mach_port_t instead of host_priv_t. * vm/vm_map.h (vm_map): Add user_wired field. * vm/vm_map.c (vm_map_setup): Initialize user_wired field to 0. (vm_map_pageable_common, vm_map_entry_delete, vm_map_copy_overwrite, vm_map_copyout_page_list, vm_map_copyin_page_list): When switching user_wired_count field of entry between 0 and non-0, accumulate the corresponding size into the user_wired field of map. * vm/vm_user.c (vm_wire): Turn host parameter into port parameter, and inline a version of convert_port_to_host_priv which records whether the host port is privileged or not. When it is not privileged, check whether the additional amount to user_wired will overcome 64KiB.
2014-11-10Fix documentation for vm_mapSamuel Thibault
doc/mach.texi (vm_map): Document that vm_map uses the address as a starting hint even when anywhere is TRUE.
2014-10-10doc: restore section `Inherited Ports'Justus Winter
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'.
