55 * This file manages the overall startup and shutdown of configd, as well
56 * as managing its door thread pool and per-thread datastructures.
57 *
58 * 1. Per-thread Datastructures
59 * -----------------------------
60 * Each configd thread has an associated thread_info_t which contains its
61 * current state. A pointer is kept to this in TSD, keyed by thread_info_key.
62 * The thread_info_ts for all threads in configd are kept on a single global
63 * list, thread_list. After creation, the state in the thread_info structure
64 * is only modified by the associated thread, so no locking is needed. A TSD
65 * destructor removes the thread_info from the global list and frees it at
66 * pthread_exit() time.
67 *
68 * Threads access their per-thread data using thread_self()
69 *
70 * The thread_list is protected by thread_lock, a leaf lock.
71 *
72 * 2. Door Thread Pool Management
73 * ------------------------------
74 * Whenever door_return(3door) returns from the kernel and there are no
75 * other configd threads waiting for requests, libdoor automatically
76 * invokes a function registered with door_server_create(), to request a new
77 * door server thread. The default function just creates a thread that calls
78 * door_return(3door). Unfortunately, since it can take a while for the new
79 * thread to *get* to door_return(3door), a stream of requests can cause a
80 * large number of threads to be created, even though they aren't all needed.
81 *
82 * In our callback, new_server_needed(), we limit ourself to two new threads
83 * at a time -- this logic is handled in reserve_new_thread(). This keeps
84 * us from creating an absurd number of threads in response to peaking load.
