| * | vfs: add NOFOLLOW flag to umount(2)Miklos Szeredi2010-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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).

| * | fs: improve remount,ro vs buffercache coherencyNick Piggin2010-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Invalidate sb->s_bdev on remount,ro. Fixes a problem reported by Jorge Boncompte who is seeing corruption trying to snapshot a minix filesystem image. Some filesystems modify their metadata via a path other than the bdev buffer cache (eg. they may use a private linear mapping for their metadata, or implement directories in pagecache, etc). Also, file data modifications usually go to the bdev via their own mappings. These updates are not coherent with buffercache IO (eg. via /dev/bdev) and never have been. However there could be a reasonable expectation that after a mount -oremount,ro operation then the buffercache should subsequently be coherent with previous filesystem modifications. So invalidate the bdev mappings on a remount,ro operation to provide a coherency point. The problem was exposed when we switched the old rd to brd because old rd didn't really function like a normal block device and updates to rd via mappings other than the buffercache would still end up going into its buffercache. But the same problem has always affected other "normal" block devices, including loop.

However, callers of the function pass only 1 as full_check, which means only whole log data blocks checking code is running all the time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nilfs_error() calls nilfs_detach_segment_constructor() if errors=remount-ro option is specified, and this may lead to a hang due to recursive locking of, for instance, nilfs->ns_segctor_sem and others. In this case, detaching segment constructor is not necessary because read-only flag is set to the filesystem and further writes are blocked. This fixes the potential hang issue by removing the nilfs_detach_segment_constructor() call from nilfs_error. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

That sounds a little bit confusing, and it may be quickly polluted espcially when growing the ocfs2_info_request ioctls afterwards(it will grow i bet). As a result, such OCFS2 IOCs do need to be placed somewhere other than ocfs2_fs.h, a separated ocfs2_ioctl.h will be added to store such ioctl structures and definitions which could also be used from userspace to invoke ioctls call.
