* Fix host architecture detection for canadian cross buildsJoerg Bornemann2019-08-083-0/+16
| | | | | | | | | | | | | | | | | If the host architecture is different from -platform (canadian cross build with -external-hostbindir) then we cannot use QMAKE_HOST.os to deduce the executable extension for that platform, because this value comes from the qmake binary that was pointed to by -external-hostbindir. Move the target name deduction mechanism to the actual configure test .pro files to make sure the right scopes are available, and write the deduced target name to a text file. That text file is read by qtConfTest_architecture to get the right binary to analyze.

* x86: Disable AVX support on 64-bit MinGWThiago Macieira2019-02-061-0/+3
| | | | | | | | | | | | | | | | | GCC for 64-bit Windows has a bug that it fails to properly re-align the stack pointer for use with 256-bit memory addresses (AVX). Therefore, there's about a 50/50 chance that any function using AVX will have an improperly-aligned stack. In release mode, stack accesses should be rare, but in debug mode they happen frequently. Either way, this is a ticking time bomb, so we disable. Clang is not affected. 32-bit MinGW is not affected. 64-bit in other OSes with GCC are not affected.

| * OpenSSL: force the "1.0.0" soname when loading OpenSSL 1.0Giuseppe D'Angelo2018-10-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Linux distributions patch OpenSSL's soname, making builds on such distributions not deployable elsewhere. The problem is that the code loading OpenSSL symbols would attempt to use the soname of the build machine, and therefore not finding the OpenSSL libraries on the deploy system. The binary builds of Qt for Linux are affected by this problem, as they build under RHEL7.4 which changes to soname of OpenSSL to a non-standard string. This makes the binary builds not pick up OpenSSL 1.0 from the machine where the build gets installed on. Given that in the pre-1.1 versions only the 1.0 series is supported, bump the minimum requirement of Qt to that. The 1.0.x releases (up to 1.0.2, at the time of this writing) have kept binary compatibility, and advertise a soname of "1.0.0", which is used by most distributions. So, if loading of OpenSSL with the build-time soname fails, try to load them with the "1.0.0" hardcoded soname. [ChangeLog][QtNetwork][SSL] OpenSSL >= 1.0 is now required to build Qt with OpenSSL support.

* | qsimd: add support for new x86 CPU featuresThiago Macieira2018-05-051-1/+33
|/ | | | | | | | | | | | | | | | | | | | | | | | | This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI, AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These features were found in the "Intel® Architecture Instruction Set Extensions and Future Features" manual, revision 30. This commit also adds support for RDPID (already in the main manual) and the Control-flow Enforcement Technology, which appears in a separate Intel paper. This new support was done by adding a new generator script so we don't have to maintain two tables in sync, one in qsimd.cpp with the feature names, and the other in qsimd_p.h. Since we now need a lot more bits, it's no longer worth keeping the two halves of the qt_cpu_features variable mostly similar to the main two CPUID results. This commit goes back to keeping things in order, like we used to prior to commit 6a8251a89b6a61258498f4af1ba7b3d5b7f7096c (Qt 5.6) At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

* | QSslSocket: OpenSSL 1.1 backendRichard J. Moore2017-07-042-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch-set implements a new QSslSocket backend based on OpenSSL 1.1. 1. General. The code in this patch was organized to achieve these (somewhat contradicting) objectives: - keep the new code free of #if-ery, as far as possible; - make it easy to clean away dead code when we're eventually able to retire out-dated OpenSSL versions; - reduce the amount of code duplication. If changes in some file/component were insignificant (~5 one-liners per file), we still use pp-checks like: #if QT_CONFIG(opensslv11) ... #else ... #endif - the logic is simple and it's still easy to clean the code if we remove the legacy back-end. Where it saved #if-ery, we also introduced 'forward-compatible' macros implementing equivalents of 1.1 functions using older OpenSSL. In case some class contains a lot of version-specific ifdefs (particularly where nested #if-ery was complex) we choose to split code into: "pre11" h/cpp files, "shared" h/cpp files (they preserve their original names, e.g qsslsocket_openssl.cpp) and "11" h/cpp files. If in future we remove the legacy back-end, "pre11" should be removed; "shared" and "11" parts - merged. 2. Configuration. We introduced a new feature 'opensslv11' which complements the pre-existing 'openssl' and 'openssl-linked' features. The 'opensslv11' feature is enabled by a simple test which either compiles successfully or ends in a compilation error, depending on a value of the OPENSSL_VERSION_NUMBER constant. If the feature was enabled, we also append an additional compilation flag -DOPENSSL_API_COMPAT=0x10100000L to make sure our new code does not contain deprecated structures, function calls, macro-invocations from OpenSSL < 1.1.

* | QRandomGenerator: use getentropy on Linux & OpenBSDThiago Macieira2017-06-302-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The getentropy function, first found in OpenBSD, is present in glibc since version 2.25 and Bionic since Android 6.0 and NDK r11. It uses the Linux 3.17 getrandom system call. Unlike glibc's getrandom() wrapper, the glibc implementation of getentropy() function is not a POSIX thread cancellation point, so we prefer to use that even though we have to break the reading into 256-byte blocks. The big advantage is that these functions work even in the absence of a /dev/urandom device node, in addition to a few cycles shaved off by not having to open a file descriptor and close it at exit. What's more, the glibc implementation blocks until entropy is available on early boot, so we don't have to worry about a failure mode. The Bionic implementation will fall back by itself to /dev/urandom and, failing that, gathering entropy from elsewhere in the system in a way it cannot fail either. uClibc has a wrapper to getrandom(2) but no getentropy(3). MUSL has neither. Change-Id: Ia53158e207a94bf49489fffd14c8cee1b968a619 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* | Add support for OpenGL ES 3.2 in QOpenGLExtraFunctionsLaszlo Agocs2017-06-302-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow the usual pattern: Add a config test and automatic include of GLES3/gl32.h if there is a GLES 3.2 capable header+lib at build time. Then, regardless of this being enabled, expose all new 3.2 API functions in QOpenGLExtraFunctions and resolve them dynamically at run time. This way 3.2 functions will be available when deployed to a 3.2 capable system (or OpenGL 3/4.x with the functions in question available) regardless of what was present in the sysroot at build time.

* | QRandomGenerator: don't internally rely on QT_HAS_INCLUDEThiago Macieira2017-06-204-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC didn't support it until version 5 or 6, so add configure tests for both <random> and <sys/auxv.h>. Normally I'd say "upgrade", but this is too low-level and important a feature. There's a good chance that all our supported compilers have <random> anyway. As for <sys/auxv.h>, it's present on Glibc, Bionic and MUSL, but I don't see it in uClibc (AT_RANDOM is a Linux-specific feature).

| * Enable stack-protector-strong for QNX 7.0.0James McDonnell2017-06-132-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was originally enabled in the mkspecs for 64-bit QNX 7.0.0 but that broke when the qtConfig change was made. It looks like qtConfig shouldn't be used in the platform mkspecs. I suspect the stack-protector changes were left out of the 32-bit mkspecs so that 6.6.0 builds wouldn't be affected. Ignore the stack-protector/stack-protector-all possibility since it isn't possible to access it without a command line option. Specifying both options doesn't even make sense since stack-protector-all encompasses stack-protector. For now, leave out command line control of this feature.
