Summary

nfsd: Fix cred ref leak in nfsd_nl_listener_set_doit().

Details

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

nfsd: Fix cred ref leak in nfsdnllistenersetdoit().

nfsdnllistenersetdoit() uses getcurrentcred() without put_cred().

As we can see from other callers, svcxprtcreatefromsa() does not require the extra refcount.

nfsdnllistenersetdoit() is always in the process context, sendmsg(), and current->cred does not go away.

Let's use currentcred() in nfsdnllistenerset_doit().
