2015-05-20ipc: replace the IPC table with a radix treeJustus Winter
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. (ipc_entry_cache): New variable. (ipc_entry_lookup): Replace with a radix tree lookup. (ipc_entry_get): The free list handling is changed a little. Adopt accordingly.

(ipc_entry_grow_table): Remove declaration. * ipc/ipc_init.c (ipc_bootstrap): Adopt initialization. * ipc/ipc_kmsg.c (ipc_kmsg_copyout_header): Use `ipc_entry_alloc' instead of re-coding it. Adopt free list handling. (ipc_kmsg_copyout_object): Adopt free list handling, store the name. * ipc/ipc_object.c (ipc_object_copyout): Likewise. (ipc_object_copyout_multiname): Likewise. * ipc/ipc_space.c (ipc_space_create): Initialize radix tree and free list. Drop table and splay tree initialization. (ipc_space_destroy): Free ipc entries and radix tree, remove table and splay tree cleanup. * ipc/ipc_space.h (struct ipc_space): Add radix tree, free list, and size. Remove all fields related to the table and splay tree. * ddb/db_print.c (db_port_iterate): Adopt iteration.

2014-12-09Retire procedure `old_mach_port_get_receive_status'Justus Winter
Retire the compatibility RPC `old_mach_port_get_receive_status' that works like `mach_port_get_receive_status' but returns an `old_mach_port_status' object that lacks the `mps_seqno' field. Do not remove the type yet, so we do not break anyones build. The RPC stubs currently distributed with the glibc require it. * include/mach/mach_port.defs (old_mach_port_get_receive_status): Drop RPC. * include/mach/mach_types.defs (old_mach_port_status_t): Drop type. * include/mach/port.h (old_mach_port_status_t): Add note to remove this for the 1.6 release. * ipc/mach_port.c (old_mach_port_get_receive_status): Drop function.

2014-05-25include: fix the embedded type definitions in memory_object.defsJustus Winter
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.
2014-04-30include: do not guard the host_slab_info RPC with MACH_VM_DEBUGJustus Winter
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.
2014-04-10include: fix the definition of device_openJustus Winter
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.
2014-04-08include: make the device_t types translation functions mutableJustus Winter
Make the intran, outtran and destructor functions mutable using preprocessor macros. Make it possible to inject imports using the DEVICE_IMPORTS macro. This way, userspace servers can provide their own translation functions. * include/device/device_types.defs: Honor DEVICE_IMPORTS. (device_t): Make the translation mutable using preprocessor macros.
2014-04-05include: make the notify_port_t types translation functions mutableJustus Winter
Make the intran, outtran and destructor functions mutable using preprocessor macros. Make it possible to inject imports using the NOTIFY_IMPORTS macro. This way, userspace servers can provide their own translation functions. * include/mach/notify.defs: Honor NOTIFY_IMPORTS. (notify_port_t): Make the translation mutable using preprocessor macros.
2014-03-25include: make the memory_object_t types translation functions mutableJustus Winter
Make the intran, outtran and destructor functions mutable using preprocessor macros. Make it possible to inject imports using the MEMORY_OBJECT_IMPORTS macro. This way, userspace servers can provide their own translation functions. * include/mach/mach_types.defs (memory_object_t): Make the translation mutable using preprocessor macros. * include/mach/memory_object.defs: Likewise for the inlined type declarations. Honor MEMORY_OBJECT_IMPORTS. * include/mach/memory_object_default.defs: Likewise.
