Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
nfsd: fix nfsd4_deleg_getattr_conflict in presence of third party lease<br />
<br />
It is not safe to dereference fl->c.flc_owner without first confirming<br />
fl->fl_lmops is the expected manager. nfsd4_deleg_getattr_conflict()<br />
tests fl_lmops but largely ignores the result and assumes that flc_owner<br />
is an nfs4_delegation anyway. This is wrong.<br />
<br />
With this patch we restore the "!= &nfsd_lease_mng_ops" case to behave<br />
as it did before the change mentioned below. This is the same as the<br />
current code, but without any reference to a possible delegation.
