"Currently overlayfs uses the mounter's credentials for its

This patches allows a caller to instruct overlayfs to use its

namespace hierarchy as the user namespace the overlayfs instance will
be mounted in. This provides a consistent and simple security model.

With this it is possible to e.g., mount an overlayfs instance where
the mounter must have CAP_SYS_ADMIN but the credentials used for

Merge tag 'vfs-6.13.ovl' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull overlayfs updates from Christian Brauner:
"Make overlayfs support specifying layers through file descriptors.

Currently overlayfs only allows specifying layers through path names.
This is inconvenient for users that want to assemble an overlayfs
mount purely based on file descriptors:

This enables user to specify both:

fsconfig(fd_overlay, FSCONFIG_SET_FD, "upperdir+", NULL, fd_upper);
fsconfig(fd_overlay, FSCONFIG_SET_FD, "workdir+", NULL, fd_work);
fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower1);
fsconfig(fd_overlay, FSCONFIG_SET_FD, "lowerdir+", NULL, fd_lower2);

in addition to:

fsconfig(fd_overlay, FSCONFIG_SET_STRING, "upperdir+", "/upper", 0);
fsconfig(fd_overlay, FSCONFIG_SET_STRING, "workdir+", "/work", 0);
fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower1", 0);
fsconfig(fd_overlay, FSCONFIG_SET_STRING, "lowerdir+", "/lower2", 0);

features and some older properties"

Christian Brauner <brauner@kernel.org> says:

Currently overlayfs only allows specifying layers through path names.
This is inconvenient for users such as systemd that want to assemble an
overlayfs mount purely based on file descriptors.

When porting overlayfs to the new mount api I already mentioned this.
This enables user to specify both:

fsconfig(fd_overlay, FSCONFIG_SET_FD, "upperdir+", NULL, fd_upper);
fsconfig(fd_overlay, FSCONFIG_SET_FD, "workdir+", NULL, fd_work);

The selftest contain an example for this.
