- Update to 3.0.11 (via patches generated from git) - Plus newer upstream fixes (also via patches generated from git) - Fix shell exit failures in make - Fix .reloc section generation - Fix CHAR8 definition - Fix "make DESTDIR=..." - Change the installed .a/.o layout - Provide makefiles for consumers to use. - Make the -devel noarch since it's just headers. - Add a bunch of compatibility symlinks for our older packages. These will go away once we've migrated everything using them in fedora to use the newer make system... Signed-off-by: Peter Jones <pjones@redhat.com>

Subject: [PATCH 23/45] Fix a minor coverity complaint in some apps
|
|
|
|
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).
|
|
|
|
This resolves both issues.
