4 * Overhaul notes;-
5 *-
6 * This code is now *mostly* thread-safe. It is now easier to understand in what-
7 * ways it is safe and in what ways it is not, which is an improvement. Firstly,-
8 * all per-class stacks and index-counters for ex_data are stored in the same-
9 * global LHASH table (keyed by class). This hash table uses locking for all-
10 * access with the exception of CRYPTO_cleanup_all_ex_data(), which must only be-
11 * called when no other threads can possibly race against it (even if it was-
12 * locked, the race would mean it's possible the hash table might have been-
13 * recreated after the cleanup). As classes can only be added to the hash table,-
14 * and within each class, the stack of methods can only be incremented, the-
15 * locking mechanics are simpler than they would otherwise be. For example, the-
16 * new/dup/free ex_data functions will lock the hash table, copy the method-
17 * pointers it needs from the relevant class, then unlock the hash table before-
18 * actually applying those method pointers to the task of the new/dup/free-
19 * operations. As they can't be removed from the method-stack, only-
20 * supplemented, there's no race conditions associated with using them outside-
21 * the lock. The get/set_ex_data functions are not locked because they do not-
22 * involve this global state at all - they operate directly with a previously-
23 * obtained per-class method index and a particular "ex_data" variable. These-
24 * variables are usually instantiated per-context (eg. each RSA structure has-
25 * one) so locking on read/write access to that variable can be locked locally-
26 * if required (eg. using the "RSA" lock to synchronise access to a-
27 * per-RSA-structure ex_data variable if required).-
