* QElfParser: rewrite using elf.hThiago Macieira2021-10-061-25/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rewrite uses the actual structures supplied by the system's C library, so it should be easier to read. It removes hardcoded constants with little evident meaning in favor of sizeof() and the macros from that header. It also removes advancing the data pointer in favor of having absolute offsets. The resulting implementation is stricter than the original, checking more fields in the header. Because the QPluginLoader and QFactoryLoader users may make decisions based on availability of plugins before attempting to load them, it's better to be stricter here than to fail later when trying to dlopen() them. Debugging and testing are much improved. Instead of stored artifacts, I added a routine to modify a valid plugin to make it invalid, given the conditions we've found so far. If you turn debugging on for this category, you'll see things like: not-elf.fcqdMq.so : Not an ELF file (invalid signature) wrong-word-size.QrnSAx.so : ELF 32-bit LSB (GNU/Linux), version 1, shared library or PIC executable, x86-64 invalid-word-size.bOkXvp.so : Invalid ELF file (class 0), LSB (GNU/Linux) unknown-word-size.ogYKeF.so : Invalid ELF file (class 66), LSB (GNU/Linux) wrong-endian.owiElX.so : ELF 64-bit MSB (GNU/Linux), version 1, shared library or PIC executable, x86-64 invalid-endian.FRxClR.so : ELF 64-bit invalid endianness (0) (GNU/Linux) unknown-endian.FfvRrP.so : ELF 64-bit invalid endianness (65) (GNU/Linux) elf-version-0.gPTdpQ.so : ELF 64-bit LSB (GNU/Linux), file version 0 elf-version-2.jlIUUg.so : ELF 64-bit LSB (GNU/Linux), file version 2 executable.LlXiFp.so : ELF 64-bit LSB (GNU/Linux), version 1, executable, x86-64 relocatable.UsOYuy.so : ELF 64-bit LSB (GNU/Linux), version 1, relocatable, x86-64 core-file.hqvNRz.so : ELF 64-bit LSB (GNU/Linux), version 1, core dump, x86-64 invalid-type.CIJgfS.so : ELF 64-bit LSB (GNU/Linux), version 1, unknown type 259, x86-64 wrong-arch.UcNmgz.so : ELF 64-bit LSB (GNU/Linux), version 1, shared library or PIC executable, AArch64 file-version-0.lZYuda.so : ELF 64-bit LSB (GNU/Linux), version 0, shared library or PIC executable, x86-64 file-version-2.ucfdwL.so : ELF 64-bit LSB (GNU/Linux), version 2, shared library or PIC executable, x86-64 no-sections.rSjsHh.so : ELF 64-bit LSB (GNU/Linux), version 1, shared library or PIC executable, x86-64 no-sections.rSjsHh.so : contains 0 sections of 64 bytes at offset 0 ; section header string table (shstrtab) is entry 0 no-sections.rSjsHh.so : no section table present, not able to find Qt metadata qtmetadata-executable.vrxcIf.so : ELF 64-bit LSB (GNU/Linux), version 1, shared library or PIC executable, x86-64 qtmetadata-executable.vrxcIf.so : contains 42 sections of 64 bytes at offset 997256 ; section header string table (shstrtab) is entry 41 qtmetadata-executable.vrxcIf.so : shstrtab section is located at offset 996831 size 423 qtmetadata-executable.vrxcIf.so : section 0 name "" type NULL flags X offset 0x0 size 0x0 qtmetadata-executable.vrxcIf.so : section 1 name ".note.gnu.property" type NOTE flags AX offset 0x2a8 size 0x30 qtmetadata-executable.vrxcIf.so : section 2 name ".note.gnu.build-id" type NOTE flags AX offset 0x2d8 size 0x24 qtmetadata-executable.vrxcIf.so : section 3 name ".hash" type HASH flags AX offset 0x300 size 0x44c qtmetadata-executable.vrxcIf.so : section 4 name ".gnu.hash" type 0x6ffffff6 flags AX offset 0x750 size 0x3b8 qtmetadata-executable.vrxcIf.so : section 5 name ".dynsym" type DYNSYM flags AX offset 0xb08 size 0xd50 qtmetadata-executable.vrxcIf.so : section 6 name ".dynstr" type STRTAB flags AX offset 0x1858 size 0x15d8 qtmetadata-executable.vrxcIf.so : section 7 name ".gnu.version" type 0x6fffffff flags AX offset 0x2e30 size 0x11c qtmetadata-executable.vrxcIf.so : section 8 name ".gnu.version_r" type 0x6ffffffe flags AX offset 0x2f50 size 0xb0 qtmetadata-executable.vrxcIf.so : section 9 name ".rela.dyn" type RELA flags AX offset 0x3000 size 0x480 qtmetadata-executable.vrxcIf.so : section 10 name ".rela.plt" type RELA flags AX offset 0x3480 size 0x7e0 qtmetadata-executable.vrxcIf.so : section 11 name ".init" type PROGBITS flags AX offset 0x4000 size 0x1b qtmetadata-executable.vrxcIf.so : section 12 name ".plt" type PROGBITS flags AX offset 0x4020 size 0x550 qtmetadata-executable.vrxcIf.so : section 13 name ".plt.got" type PROGBITS flags AX offset 0x4570 size 0x8 qtmetadata-executable.vrxcIf.so : section 14 name ".text" type PROGBITS flags AX offset 0x4580 size 0x110e qtmetadata-executable.vrxcIf.so : section 15 name ".fini" type PROGBITS flags AX offset 0x5690 size 0xd qtmetadata-executable.vrxcIf.so : section 16 name ".rodata" type PROGBITS flags AX offset 0x6000 size 0x473 qtmetadata-executable.vrxcIf.so : section 17 name ".qtversion" type PROGBITS flags AX offset 0x6478 size 0x10 qtmetadata-executable.vrxcIf.so : section 18 name ".qtmetadata" type PROGBITS flags AX offset 0x64a0 size 0x19b qtmetadata-executable.vrxcIf.so : found .qtmetadata section qtmetadata-writable.stzwrk.so : ELF 64-bit LSB (GNU/Linux), version 1, shared library or PIC executable, x86-64 Change-Id: I42eb903a916645db9900fffd16a4437af9728eea Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Q{Elf,Mach}Parser: harmonize the arguments passedThiago Macieira2021-10-041-1/+1
| | | | | | | | | | | | | | Both functions took a QString for the input file name, but while the ELF parser had an optional QLibrary pointer (which was never null) where to store the error string, the Mach-O parser received a pointer to a QString. So make both of them take a single in/out QString pointer, which has the file name on input and is cheap for us because of COW. Drive-by fix the name of the static function in qmachparser.cpp from "ns" (which stood for "not suitable") to "notfound".

* Q{Elf,Mach}Parser: simplify the return codesThiago Macieira2021-09-241-3/+2
| | | | | | | | | | | | | | | | | 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").

This simplifies the code generation a lot because now all the read<T> calls become unconditional qFromUnaligned<T>, which is just a memcpy(), which for primitive types the compiler will simply emit a memory load into a register.

* QPluginLoader: limit the amount of memory used when scanning pluginsThiago Macieira2018-07-141-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* Use QT_CONFIG(library) instead of QT_NO_LIBRARYUlf Hermann2017-03-061-2/+2
| | | | | | | | | | | | | For the windows file system engine, we add an extra macro to use library loading if configured to do so, but avoid it on WinRT, as none of the symbols would be found. We also QT_REQUIRE_CONFIG(library) in the library headers and exclude the sources from the build if library loading is disabled. This, in turn, makes it necessary to clean up some header inclusions.
