* Q{Elf,Mach}Parser: simplify the return codesThiago Macieira2021-09-241-35/+21
| | | | | | | | | | | | | | | | | The multi-state return code was a legacy of how Arvid wrote the ELF parser code back in the day, the fact that it scanned for two different types of plugins in Qt 4 and that the metadata could exist in different places. None of that matters nowadays: who cares if the file is a corrupt binary, not a valid binary, does not have the right architecture, or has no suitable section? It's not a plugin, period. The Qt 4 plugin mechanism was removed for Qt 5.0 in commit 7443895857fdaee132c8efc643e471f02b3d0fa4 ("Remove support for Qt 4 style plugins").

* QPlugin: make the macros match the scanning code for ELF systemsThiago Macieira2021-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | For ELF platforms with a GCC-compatible compiler, the QElfParser has been ignoring the .rodata section ever since Qt 5.0 commit 7443895857fdaee132c8efc643e471f02b3d0fa4 ("Remove support for Qt 4 style plugins"). That change removed handling of return value QElfParser::NoQtSection from the ELF parser, which meant that the plugins without a .qtmetadata section were never considered plugins. In other words, for those systems, the __attribute__ macro is mandatory. For systems with a GCC-incompatible compiler, there were only two in Qt 5.x's lifetime: Oracle/Sun Solaris with SunCC and IBM AIX with IBM xlC compiler. Neither compiler supports C++17 according to [1], so they can't be in use in Qt 6. IBM xlC now comes with a Clang-based front-end for users who need Qt 6 and the OpenIndiana distribution of Open Source Solaris has been using GCC since 2012. So make the macros mandatory from now on.

* QLibrary: use QStringTokenizer in isLibrary()Marc Mutz2021-08-211-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the whole function for readability _and_ performance: - Extract Method isValidSuffix() as a lambda - Extract Method isNumeric() as a lambda - Use a C array of QLatin1String instead of a QStringList to hold the statically-sized list of candidate suffixes. This has the nice side-effect that the compiler will now throw an error in case the #ifdef'ery yields zero candidates (C arrays cannot have no elements), e.g. when porting to a new platform. - Last, not least, replace the parsing with a loop that makes clear what's going on and which is forward-iteration-only-compatible, so we can use QStringTokenizer directly, without toContainer() to get a random-access sequence. Need to use the C++20 version of all_of(), since QStringTokenizer uses sentinels instead of end-iterators. Even though we use higher-level constructs now, the code is still more efficient than the index-twisting we had before.

We had reasoed that deadlocks would only occur if the object creation in instance() recursed into its own instance(), which was already a bug. But we had forgotten that dlopen()/ LoadLibrary() executes initialization code from the module being loaded, which could cause a recursion back into the same QPluginLoader or QLibrary object. This recursion is benign because the module *is* loaded and dlopen()/LoadLibrary() returns the same handle. [ChangeLog][QtCore][QLibrary and QPluginLoader] Fixed a deadlock that would happen if the plugin or library being loaded has load-time initialization code (C++ global variables) that recursed back into the same QLibrary or QPluginLoader object. PS: QLibraryPrivate::loadPlugin() updates pluginState outside a mutex lock, so pluginState should be made an atomic variable. Once that is done, we'll only need locking the mutex to update errorString (no locking before loading).

Because I had to change that, I took the opportunity to fix the QFactoryLoader code that calls loadPlugin(). Note that QLibraryPrivate::loadPlugin() returns non-nullptr now if the instance is known, which means the last return in QPluginLoader::load() will convert to true, not false, if the instance got cached between the earlier check and the call to loadPlugin().

* Plugins: store the metadata in CBOR instead of binary JSONThiago Macieira2018-09-011-18/+26
| | | | | | | | | | | | | | | In preparation for Qt 6 deprecating the binary JSON format. Also reduces the size of the metadata a little: for the xcb platform plugin, it went down from 264 bytes to 138; for the jpeg image plugin, it went from 320 to 135. I've had to change the signature so older versions of Qt won't try to parse the CBOR data as Binary JSON. Unfortunately, before QJsonDocument could get a chance to reject it, qJsonFromRawLibraryMetaData() needed to allocate memory and that causes crashes with Qt < 5.11.2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Eight bytes into the Binary JSON header there's a 32-bit little-endian size, which qJsonFromRawLibraryMetaData uses to determine the size of the stored metadata. That value is passed as a size to QByteArray, which means certain values could cause crashes due to being too big or via sign-extension in 64-bit.

| * QPluginLoader: limit the amount of memory used when scanning pluginsThiago Macieira2018-07-141-26/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using actual memory allocation, limit to 64 MB, not the full file size. On most systems, the memory map technique will work, so this won't even be tried. In any case, we don't need the fix for the OOM situation that was applied in commit e211ab76d766878b4dbe88901b9a7a4a70ce7332. As for the memory mapping technique, this commit limits the allocation to reasonable values given the virtual memory addressing space. Half a gigabyte is probably acceptable on 32-bit systems, where there should be a contiguous space for the OS to allocate the file in. This commit also fixes an overflow when converting from qint64 of the file size to ulong (32-bit on 32-bit platforms and on Windows). For 64-bit systems, we currently limit to 1 TB.

| * Handle OOM condition in the validation of plugin metadataAndre de la Rocha2018-01-191-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A large plugin dll (e.g., one with many MB of debug info) could cause a 32-bit application to crash when the entire dll file could not fit within the address space of the process. The code for validating a plugin library and retrieving metadata from it first tried to map the entire file in memory, which failed for large files, returning NULL. In this case, the code tried then to read the entire file via QFile::readAll(), which deep below caused a bad_alloc exception in malloc, resulting in the termination of the application. This change handles the case where the library could not be mapped into memory, in spite of memory mapping being supported, by reporting the error and returning false, making the plugin unavailable. [ChangeLog][QtCore][QPluginLoader] Fixed a bug that would cause the Qt plugin scanning system to allocate too much memory and possibly crash the process.
