Subject: fs/squashfs: zero out unused fields in fs_dirent
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=53ba2c21c2df142b37bb2f0d6850d79dcfd8976f;p=u-boot.git

fs/squashfs: zero out unused fields in fs_dirent

When reading directories the UEFI sub-system must supply file attributes
and timestamps. These fields will have to be added to struct fs_dirent.
SquashFS should not fill these fields with random data. Ensure that they
are zeroed out.
