rehashing the negative placeholder opens a race with d_lookup(); we unhash it almost immediately (by d_move()), but the race window is there. Since d_move() doesn't rely on target being hashed, we don't need that d_rehash() at all. Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

Add a new UMOUNT_NOFOLLOW flag to umount(2). This is needed to prevent symlink attacks in unprivileged unmounts (fuse, samba, ncpfs). Additionally, return -EINVAL if an unknown flag is used (and specify an explicitly unused flag: UMOUNT_UNUSED). This makes it possible for the caller to determine if a flag is supported or not.

It hadn't been needed since we'd sanitized the logics in mark_mounts_for_expiry() (which, in turn, used to be a rudiment of bad old times when namespace_sem was per-ns). Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

(mnt,mnt_mountpoint) pair is conceptually wrong; if you want to use it for generating pathname and for nothing else *and* if you know that vfsmount tree is unchanging, you can get away with that, but the right solution for that is (mnt,mnt_root). Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>

The handling of mount flags in set_mnt_shared() got a little tangled up during previous cleanups, with the following problems: * MNT_PNODE_MASK is defined as a literal constant when it should be a bitwise xor of other MNT_* flags * set_mnt_shared() clears and then sets MNT_SHARED (part of MNT_PNODE_MASK) * MNT_PNODE_MASK could use a comment in mount.h * MNT_PNODE_MASK is a terrible name, change to MNT_SHARED_MASK This patch fixes these problems.

No one is calling this anymore as everyone has switched to invalidate_mapping_pages long time ago. Also update a few references to it in comments. nfs has two more, but I can't easily figure what they are actually referring to, so I left them as-is.

First of all, get_source() never results in CL_PROPAGATION alone. We either get CL_MAKE_SHARED (for the continuation of peer group) or CL_SLAVE (slave that is not shared) or both (beginning of peer group among slaves). Massage the code to make that explicit, kill CL_PROPAGATION test in clone_mnt() (nothing sets CL_MAKE_SHARED without CL_PROPAGATION and in clone_mnt() we are checking CL_PROPAGATION after we'd found that there's no CL_SLAVE, so the check for CL_MAKE_SHARED would do just as well). Fix comments, while we are at it... Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
