In the Linux kernel, the following vulnerability has been resolved:

xfs: remove xfs_attr_leaf_hasname

The calling convention of xfs_attr_leaf_hasname() is problematic, because

it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer

when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a

non-NULL buffer pointer for an already released buffer when

xfs_attr3_leaf_lookup_int fails with other error values.

Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so

that the buffer release code is done by each caller of

xfs_attr3_leaf_read. (NVD)
