-/* Note: ssl_FreeSID() in sslnonce.c gets used for both client and server
- * cache sids!
- *
- * About record locking among different server processes:
- *
- * All processes that are part of the same conceptual server (serving on
- * the same address and port) MUST share a common SSL session cache.
- * This code makes the content of the shared cache accessible to all
- * processes on the same "server". This code works on Unix and Win32 only.
- *
- * We use NSPR anonymous shared memory and move data to & from shared memory.
- * We must do explicit locking of the records for all reads and writes.
- * The set of Cache entries are divided up into "sets" of 128 entries.
- * Each set is protected by a lock. There may be one or more sets protected
- * by each lock. That is, locks to sets are 1:N.
- * There is one lock for the entire cert cache.
- * There is one lock for the set of wrapped sym wrap keys.
- *
- * The anonymous shared memory is laid out as if it were declared like this:
- *
- * struct {
- * cacheDescriptor desc;
- * sidCacheLock sidCacheLocks[ numSIDCacheLocks];
- * sidCacheLock keyCacheLock;
- * sidCacheLock certCacheLock;
- * sidCacheSet sidCacheSets[ numSIDCacheSets ];
- * sidCacheEntry sidCacheData[ numSIDCacheEntries];
- * certCacheEntry certCacheData[numCertCacheEntries];
- * SSLWrappedSymWrappingKey keyCacheData[kt_kea_size][SSL_NUM_WRAP_MECHS];
- * PRUint8 keyNameSuffix[SESS_TICKET_KEY_VAR_NAME_LEN]
- * encKeyCacheEntry ticketEncKey; // Wrapped in non-bypass mode
- * encKeyCacheEntry ticketMacKey; // Wrapped in non-bypass mode
- * PRBool ticketKeysValid;
- * sidCacheLock srvNameCacheLock;
- * srvNameCacheEntry srvNameData[ numSrvNameCacheEntries ];
- * } cacheMemCacheData;
