* | Make ELF constructors/destructors workNigel Croxon2023-05-161-4/+4
|/ | | | | | | | | | | Since commit [4f8b339facb471192e021fffd5db545a0fbddbc3] Simple EFI tools like for example t.c from the apps directory crash. The reason seems to be a wrong null-pointer check in the ctors()/dtors() functions in lib/entry.c. sourceforge.net/u/davemueller Signed-off-by: Nigel Croxon <ncroxon@redhat.com>

* | | make: Fix shell exit status handlingRichard Hughes2023-04-042-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Right now whenever we have shell commands with loops, errors in the middle are accidentally ignored, and make continues to process commands. This adds 'set -e' to all of those, so they'll propagate back up. Signed-off-by: Peter Jones <pjones@redhat.com>

* | Make ELF constructors and destructors workPeter Jones2023-03-2821-55/+380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes setup and teardown functions defined with __attribute__((__constructor__) and __attribute__((__destructor__)) work in normal circumstances in EFI binaries. A couple of notes: - it implements both the old-style .ctors/.dtors methods and the newer style .init_array/.fini_array ELF constructor and destructor arrays, processed in the order: .init_array[] .ctors[] efi_main() .dtors[] .fini_array[] - Destructors will only be called if efi_main() exits using "return"; any call to Exit() will still longjmp() past them. - InitializeLib() has already been called before constructors run, so they don't need to call it (and neither does anything else.) For compatibility, it has been altered so calling it more than once is safe. - No attempt is made to handle any constructor or destructor with a prototype other than "void func(void);", but note that InitializeLib has been called, so LibImageHandle, ST, BS, and RT are set. - The init_array/ctor/dtor/fini_array lists aren't the using the GNU "CONSTRUCTOR" output section command, so they don't start with a size. - The lists are individually sorted during the link stage via SORT_BY_NAME() in the linker script. - The default (empty) init_array/ctor/dtor/fini_array lists are padded out to 8-byte alignment with ".p2align 3, 0", and each list always has at least one ".long 0" at the end of it (even if it's completely empty). As a result, they can have NULLs that need to be skipped. The sections they're in are mergeable, so the NULLs don't have to be exclusively at the end. - The ia64 and mips64el arches have not been tested. Signed-off-by: Peter Jones <pjones@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Coverity added a new kind of check, and it noticed some minor errors with some types in two of the apps here, both of the same form: 1. gnu-efi-3.0.6/apps/lfbgrid.c:91: overflow_before_widen: Potentially overflowing expression "info->VerticalResolution * info->PixelsPerScanLine" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "UINTN" (64 bits, unsigned). 1. gnu-efi-3.0.6/apps/bltgrid.c:67: overflow_before_widen: Potentially overflowing expression "info->VerticalResolution * info->HorizontalResolution" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic, and then used in a context that expects an expression of type "UINTN" (64 bits, unsigned).
