Subject: [PATCH 26/39] makeguids: initialize memory
|
|
|
5e6fc3 |
|
|
|
5e6fc3 |
so that we do not write uninitialized memory into guids.bin and names.bin
|
|
|
5e6fc3 |
which made the resulting libefivar.so.1.36 unreproducible.
|
|
|
5e6fc3 |
See https://reproducible-builds.org/ for why this matters.
