* mach_debug_types: Add const_dev_name_tSamuel Thibault2022-01-161-0/+1
| | | | This will avoid forcing the caller to respect the definite string size.
* device_types: Add const_dev_name_tSamuel Thibault2022-01-161-0/+1
| | | | This will avoid forcing the caller to respect the definite string size.
* vm_region_get_proxy: rename to create_proxySergey Bugaev2021-11-071-1/+1
| | | | For coherency with memory_object_create_proxy.
* vm: vm_region_get_proxyJoan Lledó2021-11-071-0/+10
| | | | | | | | | To get a proxy to the region a given address belongs to, with protection and range limited to the region ones. * include/mach/mach4.defs: vm_region_get_proxy RPC declaration * vm/vm_map.c: vm_region_get_proxy implementation Message-Id: <20211106081333.10366-2-jlledom@mailfence.com>
* memory_object: Fix memory_object_t type in the kernelSamuel Thibault2021-11-071-2/+6
| | | | | | | | | | mach_port_t is for userland, kernel sees the translated ipc_port_t. * include/mach/memory_object.h [MACH_KERNEL]: Include ipc/ipc_types.h [MACH_KERNEL] (memory_object_t): Typedef to ipc_port_t instead of mach_port_t. (memory_object_array_t): Typedef to memory_object_t* instead of mach_port_t*.
* memory_object_create_proxy: Make len parameter vm_size_array_tSamuel Thibault2021-10-171-1/+2

* device_read: Add dealloc for dataSamuel Thibault2021-08-211-1/+1
| | | | | | | | | It would be very tricky for the server to manage deallocation for device_read, and does not seem useful anyway. device_reply.defs already has it. * include/device/device.defs (device_read): Add dealloc flag for the data array.
* memory_object_proxy: Explicit that creation wants a send rightSamuel Thibault2021-08-091-2/+2

| | | | | | | | | | | | | | | | | This allows privileged userland drivers to allocate buffers for e.g. DMA, and thus need them to be physically contiguous and get their physical address.

* ipc: replace the IPC table with a radix treeJustus Winter2015-05-203-48/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the port names are mapped to an IPC object (e.g. a port) using a table. This, however, requires large chunks of continuous memory, and leads to scalability problems as virtual kernel memory is a scarce resource. To avoid excessive overhead, non-contiguous port names are spilled into a splay tree. Replace the IPC table with a radix tree. As the radix tree is able to store non-contiguous names with reasonable overhead, we can drop the splay tree as well. * ipc/ipc_entry.c (ipc_entry_tree_collision): Remove function.

| | | | | | | | | | | | | | | In order to use MIG translation functions to lookup memory objects, preprocessor macros have been introduced into the definition of memory_object_t in 50cc5152. The procedure definitions contain inlined type definitions in order to change the type of the argument in question (i.e. to make it polymorphic). The inline definitions however lack the destructor function, leading to reference leaks when a reference is acquired in the intran function. * include/mach/memory_object.defs: Add the destructor functions to the inlined type definitions.

| | | | | | | | | | | | | | Previously, the definition of the host_slab_info RPC was guarded with MACH_VM_DEBUG, even though it is not at all concerned with the VM subsystem. Furthermore, there was no "skip" directive for host_slab_info. The function host_slab_info is guarded with MACH_DEBUG. The server for the RPCs in mach_debug.defs is only used if MACH_DEBUG is defined. There is no need to guard host_slab_info. * include/mach_debug/mach_debug.defs (host_slab_info): Unconditionally include the RPC.
* include: fix the definition of device_openJustus Winter2014-04-101-1/+10
| | | | | | | | | | | Previously, every userspace server implementing the device protocol filtered the device definitions to replace the device_t type with mach_port_send_t to make the device argument of device_open polymorphic. Rather than doing that, which makes it impossible to use translation functions, fix the definition of device_open. * include/device/device.defs (device_open): Redefine the device argument to make it polymorphic unless a outran function is specified.
