A mount's idmapping is immutable. The only thing modified after alloc_mnt_idmap() is the reference count and that is hidden behind mnt_idmap_get() and mnt_idmap_put(). Everything else only reads from it. That is the same model struct cred uses and the idmapping is sensitive enough to deserve it. The conversion goes bottom up through the vfs{g,u}id and fs{g,u}id helpers, the privilege checks, acl, xattr and quota and then every inode operation that takes an idmap, so ->permission(), ->getattr(), ->setattr(), ->create(), ->mkdir(), ->mknod(), ->symlink(), ->rename(), ->tmpfile(), ->get_acl(), ->set_acl() and ->fileattr_set() with their implementations in every filesystem, plus the LSM hooks. struct vfsmount, struct mount_kattr and struct kstatmount store a const pointer and nop_mnt_idmap and invalid_mnt_idmap live in rodata, so anything that tries to modify them faults instead of silently corrupting the initial idmapping" * tag 'vfs-7.4-rc1.idmap' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (27 commits) fs: make nop_mnt_idmap and invalid_mnt_idmap const fs: port mnt_idmap() and file_mnt_idmap() to const mnt_idmap fs: port vfs_*() helpers to const mnt_idmap fs: port ->setattr() to pass const mnt_idmap fs: port ->getattr() to pass const mnt_idmap fs: port ->create() to pass const mnt_idmap fs: port ->symlink() to pass const mnt_idmap fs: port ->mkdir() to pass const mnt_idmap fs: port ->rename() to pass const mnt_idmap fs: port ->mknod() to pass const mnt_idmap fs: port ->tmpfile() to pass const mnt_idmap fs: port ->get_acl() to pass const mnt_idmap fs: port ->set_acl() to pass const mnt_idmap fs: port ->fileattr_set() to pass const mnt_idmap fs: port xattr to const mnt_idmap fs: port ->permission() to pass const mnt_idmap fs: port acl to const mnt_idmap fs: port inode_init_owner() to const mnt_idmap fs: port inode_owner_or_capable() to const mnt_idmap fs: port privilege checking helpers to const mnt_idmap ...		2026-10-19 17:57:49 -10:00
