Bruce Fields" To: Trond Myklebust , Anna Schumaker Cc: linux-nfs@vger.kernel.org, Andreas Gruenbacher Subject: NFSv4.2 mode_umask support Date: Wed, 23 Nov 2016 15:41:38 -0500 Message-Id: <1479933700-5743-1-git-send-email-bfields@redhat.com> Sender: linux-nfs-owner@vger.kernel.org List-ID: Resending--can we get any opinions on these? The following patches allow the umask to be ignored in the presence of inheritable NFSv4 ACLs. Otherwise inheritable ACLs can be rendered mostly useless whenever the umask masks out group bits. This solves a problem we've seen complaints about for some time, both upstream and from RHEL users. The new protocol has been discussed in the IETF working group and is documented at: https://tools.ietf.org/html/draft-ietf-nfsv4-umask-02 It's unlikely that we'll discover problems requiring an incompatible change, so I think we should consider this for 4.10. --b.
