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_free_name): New function. (ipc_entry_alloc): Adopt accordingly. (ipc_entry_alloc_name): Likewise. (ipc_entry_dealloc): Likewise. (ipc_entry_grow_table): Remove function. * ipc/ipc_entry.h (struct ipc_entry): Update comment, add field for name and free list, remove unused fields. (ipc_entry_cache, ie_alloc, ie_free): New declarations. (struct ipc_tree_entry): Remove. Also remove any related declarations. (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. (db_lookup_port): Adopt lookup. * include/mach_debug/ipc_info.h: Remove unused parts of the debug interface. * include/mach_debug/mach_debug.defs: Likewise. * include/mach_debug/mach_debug_types.defs: Likewise. * ipc/mach_debug.c: Likewise. * ipc/ipc_right.c (ipc_right_reverse): Adopt lookup, store name.

2015-05-20ipc: replace reverse hash table with a radix treeJustus Winter
Currently, there is a hash table mapping (space, object) tuples to `ipc_entry' objects. This hash table is intertwined with the IPC tables. There is one hash table per IPC space, but it is only for the entries in the IPC table. This hash table is called `local' in the source. All IPC entries being spilled into the splay tree are instead mapped by a global hash table. Replace the local (i.e. per IPC space) reverse hash table with a radix tree. * ipc/ipc_entry.c (ipc_entry_grow_table): Adjust accordingly. * ipc/ipc_entry.h (struct ipc_entry): Adjust comment. * ipc/ipc_hash.c: Adjust comment explaining the local lookup table. (IPC_LOCAL_HASH_INVARIANT): New macro. (ipc_hash_local_lookup): Use the new `ipc_reverse_lookup' function. (ipc_hash_local_insert): Use the new `ipc_reverse_insert' function. (ipc_hash_local_delete): Use the new `ipc_reverse_remove' function. * ipc/ipc_space.c (ipc_space_create): Initialize radix tree. (ipc_space_destroy): Free radix tree. * ipc/ipc_space.h (struct ipc_space): Add radix tree. (ipc_reverse_insert): New function. (ipc_reverse_remove): Likewise. (ipc_reverse_remove_all): Likewise. (ipc_reverse_lookup): Likewise. * ipc/ipc_right.c (ipc_right_clean): Update comment.
2015-05-20ipc: undo manual inlining of `ipc_entry_X' functionsJustus Winter
Today we can rely on the compiler to inline functions. Undoing this manual optimization is a first step to replace the IPC tables. * ipc/mach_msg.c (mach_msg_trap): Undo the manual inlining of `ipc_entry_lookup', `ipc_entry_dealloc', and `ipc_entry_get'. * ipc/ipc_kmsg.c (ipc_kmsg_copyin_header, ipc_kmsg_copyout_header): Likewise. * kern/exception.c (exception_raise): Likewise. * kern/ipc_mig.c (fast_send_right_lookup): Likewise.
2015-05-19kern: import `macros.h' from x15Justus Winter
Import the macro definitions from the x15 kernel project, and replace all similar definitions littered all over the place with it. Importing this file will make importing code from the x15 kernel easier. We are already using the red-black tree implementation and the slab allocator from it, and we will import even more code in the near future. * kern/list.h: Do not define `structof', include `macros.h' instead. * kern/rbtree.h: Likewise. * kern/slab.c: Do not define `ARRAY_SIZE', include `macros.h' instead. * i386/grub/misc.h: Likewise. * i386/i386/xen.h: Do not define `barrier', include `macros.h' instead. * kern/macro_help.h: Delete file. Replaced by `macros.h'. * kern/macros.h: New file. * Makefrag.am (libkernel_a_SOURCES): Add new file, remove old file. * device/dev_master.h: Adopt accordingly. * device/io_req.h: Likewise. * device/net_io.h: Likewise. * i386/intel/read_fault.c: Likewise. * ipc/ipc_kmsg.h: Likewise. * ipc/ipc_mqueue.h: Likewise. * ipc/ipc_object.h: Likewise. * ipc/ipc_port.h: Likewise. * ipc/ipc_space.h: Likewise. * ipc/ipc_splay.c: Likewise. * ipc/ipc_splay.h: Likewise. * kern/assert.h: Likewise. * kern/ast.h: Likewise. * kern/pc_sample.h: Likewise. * kern/refcount.h: Likewise. * kern/sched.h: Likewise. * kern/sched_prim.c: Likewise. * kern/timer.c: Likewise. * kern/timer.h: Likewise. * vm/vm_fault.c: Likewise. * vm/vm_map.h: Likewise. * vm/vm_object.h: Likewise. * vm/vm_page.h: Likewise.

2014-12-16ipc: tune size of cached kernel message buffersJustus Winter
The previous limit was 256 bytes. That seems a little crummy by todays standards, and we are frequently sending bigger packets (e.g. every RPC containing a string_t on Hurd). Use the page size for IKM_SAVED_KMSG_SIZE to make sure the page is pinned to a single processor. * ipc/ipc_kmsg.h (IKM_SAVED_KMSG_SIZE): Define to `PAGE_SIZE'.
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.

2014-10-01ipc: provide the protected payload in ipc_kmsg_copyout_headerJustus Winter

2014-10-01ipc: add protected payloadJustus Winter
Add a field ip_protected_payload and a flag ip_has_protected_payload to struct ipc_port. Clear the protected payload when a receive port is moved from one ipc space to another. This is done to retain the old behavior of mach_msg, so that a port name is sent in the msgh_local_port field. If the new owner of that receive right wishes to use the protected payload mechanism, it has to be explicitly set again. * ipc/ipc_port.h (struct ipc_port): Add field ip_protected_payload. (ipc_port_set_protected_payload): Add function declaration. (ipc_port_clear_protected_payload): Likewise. (ipc_port_flag_protected_payload): Add accessor for the protected payload flag.

(ipc_port_print): Print protected_payload. (ipc_port_set_protected_payload): New function. (ipc_port_clear_protected_payload): Likewise. (ipc_port_destroy): Clear the payload when moving a receive port. * ipc/ipc_right.c (ipc_right_copyin): Likewise.
