Ahmed Arif 45303a2782 [PEFIXUP] Recalculate checksums for kernel-mode images (#8969) 
lld can leave the PE checksum field zero for reproducible output. This is acceptable for user-mode images, but Windows rejects kernel-mode images without a valid checksum.

Keep preserving linker-produced zero checksums for other images, but force checksum recalculation when pefixup is operating on a kernel-mode image.

This was found while validating Clang-built amd64 kmtest drivers against Windows 7: the same driver source built with GCC loaded, while the Clang/lld-built .sys failed with ERROR_BAD_EXE_FORMAT / 0xC1. Recalculating the PE checksum made the Clang-built driver load and the tests run correctly.

Hermès Bélusca-Maïto 9e0a3cdf6c [PEFIXUP] Add support for overriding the attributes of specific PE sections. (#3598) 
Use a syntax identical to the one from the EDITBIN tool:
--section:name[=newname][,[[!]{CDEIKOMPRSUW}][A{1248PTSX}]]

Hermès Bélusca-Maïto eb29a33169 [PEFIXUP] Section names are case-sensitive, so we can just use strncmp() instead of the non-standard strncasecmp() for names comparisons. (#3598) 2021-05-05 19:15:02 +02:00
Hermès Bélusca-Maïto ea26767353 [PEFIXUP] Avoid multi-level nesting of code with the error handling done at the very end. Use size_t variables for file sizes. (#3598) 2021-05-05 19:15:01 +02:00
Hermès Bélusca-Maïto 88b933330d [PEFIXUP] Only recalculate the PE checksum if the image is not from a reproducible build (original checksum == 0). (#3598) 2021-05-05 19:15:01 +02:00
Hermès Bélusca-Maïto 7ad33940c2 [PEFIXUP] Use vfprintf() with the va_args list. (#3598) 2021-05-05 19:14:57 +02:00
Jérôme Gardou e55123a6a2 [CMAKE] Add the kernel module type

Jérôme Gardou 5489efcb1a [SDK:TOOLS] Add --driver option to pefixup 
For now, this adds IMAGE_SCN_MEM_DISCARDABLE to the INIT section, and IMAGE_SCN_MEM_NOT_PAGED to sections which are not named PAGE or .reloc

Mark Jansen 0b948581fc [SDK][HOST-TOOLS] Add load_config workaround for gcc builds 
Since binutils can not add this, we re-introduce pefixup.
It searches for the exported symbol '_load_config_used',
and uses that to fill out the LOAD_CONFIG directory in the PE header
