Mon, 17 Aug 2026 22:38:36 +0200

Merge tag 'vfs-7.3-rc1.ovl' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfsPull overlayfs updates from Christian Brauner: "This lets the merged overlayfs mount itself be idmapped through mount_setattr(MOUNT_ATTR_IDMAP), in addition to the already supported idmapped lower and upper layers. The same overlay tree can then be exposed under a different ownership view. Overlayfs already normalizes every underlying id through the relevant layer idmap when ovl_copyattr() copies attributes into the overlay inode. So the overlay inode's i_uid and i_gid are overlay-final ids. The overlay mount idmap composes on top of that and is applied at the overlay-inode boundary only while the underlying layers keep being accessed with the mounter's credentials through their own (possibly idmapped) mounts. So this only changes how the caller sees the overlay inode and never widens the mounter's access to the layers. The second, mounter-credential check in ovl_permission() against the real inode stays on the layer idmap. Most paths need no change because the VFS applies the mount idmap to the overlay inode before overlayfs runs or after it returns at the syscall boundary. Overlayfs only has to change where it bypasses the generic path.

68f0e94b5850289c103278497457652b18c7355f - Merge patch series "ovl: support idmapped overlay mounts"

Thu, 25 Jun 2026 12:40:26 +0200

Merge patch series "ovl: support idmapped overlay mounts"Christian Brauner says:ovl: support idmapped overlay mountsI've been asked about this feature multiple times and had actuallyimplemented it right when I did the initial idmapped layer support.So here's a new version of this series.This series lets the merged overlayfs mount itself be idmapped viamount_setattr(MOUNT_ATTR_IDMAP), in addition to the already supportedidmapped lower and upper layers. It allows the same overlay tree tobe exposed under a different ownership view, e.g. a container seeingthe merged tree as 0:0 regardless of the on-disk or per-layer ids.Overlayfs already normalizes every underlying id through the relevantlayer idmap when it copies attributes into the overlay inode(ovl_copyattr()), so the overlay inode's i_{u,g}id are "overlay-final"ids. The overlay mount idmap O composes on top of that pivot: caller view <--O--> overlay-final id <--layer idmap--> on-diskO is applied at the overlay-inode boundary only - permission, getattr,setattr, the ACL owner checks and inode_init_owner() - while theunderlying layers keep being accessed with the mounter's credentialsthrough their own, possibly idmapped, mounts. The mount idmap thusonly changes how the caller sees the overlay inode and never widensthe mounter's access to the layers: the second, mounter-credentialcheck in ovl_permission() against the real inode stays on the layeridmap.Most paths need no change because the VFS applies O to the overlayinode before overlayfs runs (sticky/rename/unlink/create gating) orafter it returns at the syscall boundary (the POSIX ACL get/settranslation). Overlayfs only acts where it bypasses the generic path:getattr (it stats the real path), the setattr forward to the upper(the requested id is rebased from O into overlay-final space beforebeing handed down), inode_init_owner() on create/tmpfile, and its ownowner checks in ovl_set_acl().FS_ALLOW_IDMAP is set last, once every operation honors O, so there isno bisection point where the mount is idmappable but an operationstill ignores the idmapping.Note that fstests will be broken by this temporarily as they rely on theability to create whiteouts for unprivileged device node creation. Thatcan be adjusted.* patches from https://patch.msgid.link/20260615-work-idmapped-overlayfs-v1-0-7381632aa402@kernel.org: ovl: document security.capability idmapping on the xattr forward paths selftests/filesystems/overlayfs: test idmapped overlay mounts selftests/filesystems/overlayfs: fix set_layers_via_fds link error docs: document idmapped overlay mounts ovl: allow idmapping overlay mounts ovl: handle idmapped mounts in ovl_set_acl() ovl: handle idmapped mounts in ovl_getattr() ovl: handle idmapped mounts in ovl_setattr() ovl: handle idmapped mounts in ovl_permission() ovl: handle idmapped mounts in ovl_create_object() and ovl_tmpfile()Link: https://patch.msgid.link/20260615-work-idmapped-overlayfs-v1-0-7381632aa402@kernel.orgSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/overlayfs/Makefile

Mon, 15 Jun 2026 15:19:58 +0200

selftests/filesystems/overlayfs: test idmapped overlay mountsAdd a selftest for idmapping the merged overlay mount itself. Itapplies an idmapping to a freshly created (still detached) overlaymount with mount_setattr(MOUNT_ATTR_IDMAP) and checks that: - getattr reports ownership mapped through the mount idmap; - a file created through the idmapped mount is stored on the upper layer with the corresponding overlay-final id; - chown through the idmapped mount round-trips; - an nfs_export overlay can be idmapped and decodable file handles round-trip through it with correctly mapped ownership.The layers live on a private tmpfs and are owned by the host id so thatthey map to id 0 through the test idmapping, allowing the root callerto operate on them.Link: https://patch.msgid.link/20260615-work-idmapped-overlayfs-v1-9-7381632aa402@kernel.orgReviewed-by: Amir Goldstein Signed-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/overlayfs/Makefile

Merge patch series "filesystems selftests cleanups and fanotify test"Amir Goldstein says:This adds a test for fanotify mount ns notifications inside userns [1].While working on the test I ended up making lots of cleanups to reducebuild dependency on make headers_install.These patches got rid of the dependency for my kvm setup for theaffected filesystems tests.Building with TOOLS_INCLUDES dir was recommended by John Hubbard [2].NOTE #1: these patches are based on a merge of vfs-6.16.mount(changes wrappers.h) into v6.15-rc5 (changes mount-notify_test.c),so if this cleanup is acceptable, we should probably setup a selftestsbranch for 6.16, so that it can be used to test the fanotify patches.NOTE #2: some of the defines in wrappers.h are left for overlayfs andmount_setattr tests, which were not converted to use TOOLS_INCLUDES.I did not want to mess with those tests.* patches from https://lore.kernel.org/20250509133240.529330-1-amir73il@gmail.com: selftests/fs/mount-notify: add a test variant running inside userns selftests/filesystems: create setup_userns() helper selftests/filesystems: create get_unique_mnt_id() helper selftests/fs/mount-notify: build with tools include dir selftests/mount_settattr: remove duplicate syscall definitions selftests/pidfd: move syscall definitions into wrappers.h selftests/fs/statmount: build with tools include dir selftests/filesystems: move wrapper.h out of overlayfs subdirLink: https://lore.kernel.org/20250509133240.529330-1-amir73il@gmail.comSigned-off-by: Christian Brauner List of files: /linux/tools/testing/selftests/filesystems/overlayfs/Makefile
