+ Salt network cache hashes
+ https://bugs.webkit.org/show_bug.cgi?id=164924
+
+ Reviewed by Alex Christensen.
+
+ To enhance privacy make cache content unidentifiable from file names alone.
+ This is done by generating a unique persistent salt for each cache instance.
+ It is used when computing hashes used in file names.
+
+ The patch also replaces plain text partition directory names with salted hashes.
+
+ * NetworkProcess/cache/NetworkCache.cpp:
+ (WebKit::NetworkCache::Cache::makeCacheKey):
+ (WebKit::NetworkCache::makeCacheKey): Deleted.
+ * NetworkProcess/cache/NetworkCache.h:
+
+ Increment cache version.
+
+ * NetworkProcess/cache/NetworkCacheBlobStorage.cpp:
+ (WebKit::NetworkCache::BlobStorage::BlobStorage):
+ (WebKit::NetworkCache::BlobStorage::add):
+ (WebKit::NetworkCache::BlobStorage::get):
+
+ Use salt for blob content hash.
+
+ * NetworkProcess/cache/NetworkCacheBlobStorage.h:
+ * NetworkProcess/cache/NetworkCacheData.cpp:
+ (WebKit::NetworkCache::computeSHA1):
+
+ For simplicity all SHA1s are now salted.
+
+ (WebKit::NetworkCache::makeSalt):
+ (WebKit::NetworkCache::readOrMakeSalt):
+
+ Read salt if it exists, generate and persist it otherwise.
+
+ * NetworkProcess/cache/NetworkCacheData.h:
+ * NetworkProcess/cache/NetworkCacheKey.cpp:
+ (WebKit::NetworkCache::Key::Key):
+
+ Remove the "No partition" string and just empty.
+ That was only needed to have a directory name of some sort.
+
+ (WebKit::NetworkCache::Key::computeHash):
+
+ Use salt for key hash.
+
+ (WebKit::NetworkCache::Key::computePartitionHash):
+
+ Separate hash for partition.
+
+ * NetworkProcess/cache/NetworkCacheKey.h:
+ * NetworkProcess/cache/NetworkCacheSpeculativeLoadManager.cpp:
+ (WebKit::NetworkCache::makeSubresourcesKey):
+ (WebKit::NetworkCache::SpeculativeLoadManager::PendingFrameLoad::saveToDiskIfReady):
+ (WebKit::NetworkCache::SpeculativeLoadManager::retrieveSubresourcesEntry):
+ * NetworkProcess/cache/NetworkCacheStorage.cpp:
+ (WebKit::NetworkCache::makeSaltFilePath):
+ (WebKit::NetworkCache::Storage::open):
+
+ Cache can't be opened if we can't read or persist a salt.
+
+ (WebKit::NetworkCache::traverseRecordsFiles):
+ (WebKit::NetworkCache::Storage::Storage):
+ (WebKit::NetworkCache::Storage::synchronize):
+ (WebKit::NetworkCache::Storage::recordDirectoryPathForKey):
+
+ Use the partition hash in the directory name instead of a plain text name.
+
+ (WebKit::NetworkCache::decodeRecordHeader):
+ (WebKit::NetworkCache::Storage::readRecord):
+ (WebKit::NetworkCache::Storage::encodeRecord):
+ (WebKit::NetworkCache::Storage::traverse):
+ (WebKit::NetworkCache::Storage::clear):
+ * NetworkProcess/cache/NetworkCacheStorage.h:
+ (WebKit::NetworkCache::Storage::salt):
