Message-Id: <cover.1429868795.git.agruenba@redhat.com> Date: Fri, 24 Apr 2015 13:03:57 +0200 From: Andreas Gruenbacher <andreas.gruenbacher@...il.com> To: linux-kernel@...r.kernel.org, linux-fsdevel@...r.kernel.org, linux-nfs@...r.kernel.org, linux-api@...r.kernel.org, samba-technical@...ts.samba.org, linux-security-module@...r.kernel.org Subject: [RFC v3 00/45] Richacls Hello, here's another update of the richacl patch queue. The changes since the last posting (https://lwn.net/Articles/638242/) include: * The nfs client now allocates pages for received acls on demand like the server does. It no longer caches the acl size between calls. * All possible acls consisting of only owner@, group@, and everyone@ entries which are equivalent to the file mode permission bits are now recognized. This is needed because by the NFSv4 specification, the nfs server must translate the file mode permission bits into an acl if it supports acls at all. * Support for the dacl attribute over NFSv4.1 for Automatic Inheritance, and also for the write_retention and write_retention_hold permissions. * The richacl_compute_max_masks() documentation has been improved. * Various minor bug fixes. The git version is available here: git://git.kernel.org/pub/scm/linux/kernel/git/agruen/linux-richacl.git \ richacl-2015-04-24 The richacl command-line has been split into getrichacl and setrichacl, in line with getfacl and setfacl. Watch out for that when updating the user-space. Things still to be done, or which I'm not entirely happy with: * The nfs server performs some access checking on its own before calling into the vfs which is rersponsible for the actual access checking (see where it calls inode_permission()). With the additional MAY_ flags introduced in this patch queue, it gets it wrong in some cases; I have yet to figure out how to deal with this. * We may still need to add back support for the "system.nfs4_acl" attribute on nfs mounts for backwards compatibility; it's not clear to me if anyone is actually using that. * It would be nice if the MAY_DELETE_SELF flag could override the sticky directory check as it did in the previous version of this patch queue. I couldn't come up with a clean way of achieving that, though. * The base_acl code is still rather ugly.
