In the function grub_cryptodisk_endecrypt(), a for loop is incrementing the
variable i by (1U << log_sector_size). The variable i is of type grub_size_t
which is a 64-bit unsigned integer on x86_64 architecture. On the other hand, 1U
is a 32-bit unsigned integer. By performing a left shift on a 32-
The abiltiy to build with clang was broken in the last release after the
upgrade of gnulib.
There were two main issues:
- The use of __builtin_trap in the abort() macro.
This builtin doesn't exist for clang builds
After some discussion between Daniel and Vladimir, it was requested that I
The recent gnulib updates require an implemention of abort(), but the
current macro provided by changeset:
cd37d3d3916c gnulib: Drop no-abort.patch
to config.h.in does not work with the clang compiler since it doesn't
provide a __builtin_trap implementation, so this element of the
changeset need
Building the current code with clang and the latest gnulib fails due to
the use of a variable-length-array (vla) warning, which turns in to an
error due to the presence of the -Werror during the build.
The gnulib team stated that their code should not be built with -Werror.
At present, the only w

Hi Alec,
This looks good, thanks for fixing it.
