For quite some time the security model of overlayfs has been that operations on underlying layers shall be performed with the privileges of the mounting task. This way an unprvileged user cannot gain privileges by the act of mounting an overlayfs instance. A full audit of all function calls made by the overlayfs code has been performed to see whether they conform to this model, and this branch contains some fixes in this regard. - Support running on copied filesystem images by optionally disabling UUID verification. - Bug fixes as well as documentation updates. * tag 'ovl-update-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/vfs: ovl: unprivieged mounts ovl: do not get metacopy for userxattr ovl: do not fail because of O_NOATIME ovl: do not fail when setting origin xattr ovl: user xattr ovl: simplify file splice ovl: make ioctl() safe ovl: check privs before decoding file handle vfs: verify source area in vfs_dedupe_file_range_one() vfs: move cap_convert_nscap() call into vfs_setxattr() ovl: fix incorrect extent info in metacopy case ovl: expand warning in ovl_d_real() ovl: document lower modification caveats ovl: warn about orphan metacopy ovl: doc clarification ovl: introduce new "uuid=off" option for inodes index feature ovl: propagate ovl_fs to ovl_decode_real_fh and ovl_encode_real_fh		2020-12-17 11:42:48 -08:00
