| H A D | xattr.c | 290ab230 Thu Dec 01 13:51:58 CST 2016 Eric Biggers <ebiggers@google.com> ext4: don't read out of bounds when checking for in-inode xattrs
With i_extra_isize equal to or close to the available space, it was
possible for us to read past the end of the inode when trying to detect
or validate in-inode xattrs. Fix this by checking for the needed extra
space first.
This patch shouldn't have any noticeable effect on
non-corrupted/non-malicious filesystems.
