Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfs: remove xfs_attr_leaf_hasname<br /> <br /> The calling convention of xfs_attr_leaf_hasname() is problematic, because<br /> it returns a NULL buffer when xfs_attr3_leaf_read fails, a valid buffer<br /> when xfs_attr3_leaf_lookup_int returns -ENOATTR or -EEXIST, and a<br /> non-NULL buffer pointer for an already released buffer when<br /> xfs_attr3_leaf_lookup_int fails with other error values.<br /> <br /> Fix this by simply open coding xfs_attr_leaf_hasname in the callers, so<br /> that the buffer release code is done by each caller of<br /> xfs_attr3_leaf_read.
