Typically, +for every open(), stat() etc., the dentry corresponding to the +pathname will be looked up by walking the tree starting with the first +component of the pathname and using that dentry along with the next +component to look up the next level and so on. Since it is a frequent +operation for workloads like multiuser environments and web servers, +it is important to optimize this path. + +Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in +every component during path look-up. Since 2.5.10 onwards, fast-walk +algorithm changed this by holding the dcache_lock at the beginning and +walking as many cached path component dentries as possible. This +significantly decreases the number of acquisition of +dcache_lock. However it also increases the lock hold time +significantly and affects performance in large SMP machines. Since +2.5.62 kernel, dcache has been using a new locking model that uses RCU +to make dcache look-up lock-free. + +The current dcache locking model is not very different from the +existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock +protected the hash chain, d_child, d_alias, d_lru lists as well as +d_inode and several other things like mount look-up. RCU-based changes +affect only the way the hash chain is protected. For everything else +the dcache_lock must be taken for both traversing as well as +updating. The hash chain updates too take the dcache_lock. The +significant change is the way d_lookup traverses the hash chain, it +doesn't acquire the dcache_lock for this and rely on RCU to ensure +that the dentry has not been *freed*. + + +Dcache locking details +====================== + +For many multi-user workloads, open() and stat() on files are very +frequently occurring operations. Both involve walking of path names to +find the dentry corresponding to the concerned file. In 2.4 kernel, +dcache_lock was held during look-up of each path component. Contention +and cache-line bouncing of this global lock caused significant +scalability problems. With the introduction of RCU in Linux kernel, +this was worked around by making the look-up of path components during +path walking lock-free. + + +Safe lock-free look-up of dcache hash table +=========================================== + +Dcache is a complex data structure with the hash table entries also +linked together in other lists. In 2.4 kernel, dcache_lock protected +all the lists. We applied RCU only on hash chain walking. The rest of +the lists are still protected by dcache_lock. Some of the important +changes are : + +1. The deletion from hash chain is done using hlist_del_rcu() macro + which doesn't initialize next pointer of the deleted dentry and + this allows us to walk safely lock-free while a deletion is + happening. + +2. Insertion of a dentry into the hash table is done using + hlist_add_head_rcu() which take care of ordering the writes - the + writes to the dentry must be visible before the dentry is + inserted. This works in conjunction with hlist_for_each_rcu() while + walking the hash chain. The only requirement is that all + initialization to the dentry must be done before + hlist_add_head_rcu() since we don't have dcache_lock protection + while traversing the hash chain. This isn't different from the + existing code. + +3. The dentry looked up without holding dcache_lock by cannot be + returned for walking if it is unhashed. It then may have a NULL + d_inode or other bogosity since RCU doesn't protect the other + fields in the dentry. We therefore use a flag DCACHE_UNHASHED to + indicate unhashed dentries and use this in conjunction with a + per-dentry lock (d_lock). Once looked up without the dcache_lock, + we acquire the per-dentry lock (d_lock) and check if the dentry is + unhashed. If so, the look-up is failed. If not, the reference count + of the dentry is increased and the dentry is returned. + +4. Once a dentry is looked up, it must be ensured during the path walk + for that component it doesn't go away. In pre-2.5.10 code, this was + done holding a reference to the dentry. dcache_rcu does the same. + In some sense, dcache_rcu path walking looks like the pre-2.5.10 + version. + +5. All dentry hash chain updates must take the dcache_lock as well as + the per-dentry lock in that order. dput() does this to ensure that + a dentry that has just been looked up in another CPU doesn't get + deleted before dget() can be done on it. + +6. There are several ways to do reference counting of RCU protected + objects. One such example is in ipv4 route cache where deferred + freeing (using call_rcu()) is done as soon as the reference count + goes to zero. This cannot be done in the case of dentries because + tearing down of dentries require blocking (dentry_iput()) which + isn't supported from RCU callbacks. Instead, tearing down of + dentries happen synchronously in dput(), but actual freeing happens + later when RCU grace period is over. This allows safe lock-free + walking of the hash chains, but a matched dentry may have been + partially torn down. The checking of DCACHE_UNHASHED flag with + d_lock held detects such dentries and prevents them from being + returned from look-up. + + +Maintaining POSIX rename semantics +================================== + +Since look-up of dentries is lock-free, it can race against a +concurrent rename operation. For example, during rename of file A to +B, look-up of either A or B must succeed. So, if look-up of B happens +after A has been removed from the hash chain but not added to the new +hash chain, it may fail. Also, a comparison while the name is being +written concurrently by a rename may result in false positive matches +violating rename semantics. Issues related to race with rename are +handled as described below : + +1. Look-up can be done in two ways - d_lookup() which is safe from + simultaneous renames and __d_lookup() which is not. If + __d_lookup() fails, it must be followed up by a d_lookup() to + correctly determine whether a dentry is in the hash table or + not. d_lookup() protects look-ups using a sequence lock + (rename_lock). + +2. The name associated with a dentry (d_name) may be changed if a + rename is allowed to happen simultaneously. To avoid memcmp() in + __d_lookup() go out of bounds due to a rename and false positive + comparison, the name comparison is done while holding the + per-dentry lock. This prevents concurrent renames during this + operation. + +3. Hash table walking during look-up may move to a different bucket as + the current dentry is moved to a different bucket due to rename. + But we use hlists in dcache hash table and they are + null-terminated. So, even if a dentry moves to a different bucket, + hash chain walk will terminate. [with a list_head list, it may not + since termination is when the list_head in the original bucket is + reached]. Since we redo the d_parent check and compare name while + holding d_lock, lock-free look-up will not race against d_move(). + +4. There can be a theoretical race when a dentry keeps coming back to + original bucket due to double moves. Due to this look-up may + consider that it has never moved and can end up in a infinite loop. + But this is not any worse that theoretical livelocks we already + have in the kernel. + + +Important guidelines for filesystem developers related to dcache_rcu +==================================================================== + +1. Existing dcache interfaces (pre-2.5.62) exported to filesystem + don't change. Only dcache internal implementation changes. However + filesystems *must not* delete from the dentry hash chains directly + using the list macros like allowed earlier. They must use dcache + APIs like d_drop() or __d_drop() depending on the situation. + +2. d_flags is now protected by a per-dentry lock (d_lock).

Pages of data read from +backing store (usually the block device the filesystem is mounted on) are kept +around in case it's needed again, but marked as clean (freeable) in case the +Virtual Memory system needs the memory for something else. Similarly, data +written to files is marked clean as soon as it has been written to backing +store, but kept around for caching purposes until the VM reallocates the +memory. A similar mechanism (the dentry cache) greatly speeds up access to +directories. + +With ramfs, there is no backing store. Files written into ramfs allocate +dentries and page cache as usual, but there's nowhere to write them to. +This means the pages are never marked clean, so they can't be freed by the +VM when it's looking to recycle memory. + +The amount of code required to implement ramfs is tiny, because all the +work is done by the existing Linux caching infrastructure. Basically, +you're mounting the disk cache as a filesystem. Because of this, ramfs is not +an optional component removable via menuconfig, since there would be negligible +space savings. + +ramfs and ramdisk: +------------------ + +The older "ram disk" mechanism created a synthetic block device out of +an area of ram and used it as backing store for a filesystem. This block +device was of fixed size, so the filesystem mounted on it was of fixed +size. Using a ram disk also required unnecessarily copying memory from the +fake block device into the page cache (and copying changes back out), as well +as creating and destroying dentries. Plus it needed a filesystem driver +(such as ext2) to format and interpret this data. + +Compared to ramfs, this wastes memory (and memory bus bandwidth), creates +unnecessary work for the CPU, and pollutes the CPU caches. (There are tricks +to avoid this copying by playing with the page tables, but they're unpleasantly +complicated and turn out to be about as expensive as the copying anyway.) +More to the point, all the work ramfs is doing has to happen _anyway_, +since all file access goes through the page and dentry caches. The ram +disk is simply unnecessary, ramfs is internally much simpler. + +Another reason ramdisks are semi-obsolete is that the introduction of +loopback devices offered a more flexible and convenient way to create +synthetic block devices, now from files instead of from chunks of memory. +See losetup (8) for details. + +ramfs and tmpfs: +---------------- + +One downside of ramfs is you can keep writing data into it until you fill +up all memory, and the VM can't free it because the VM thinks that files +should get written to backing store (rather than swap space), but ramfs hasn't +got any backing store. Because of this, only root (or a trusted user) should +be allowed write access to a ramfs mount. + +A ramfs derivative called tmpfs was created to add size limits, and the ability +to write the data to swap space. Normal users can be allowed write access to +tmpfs mounts. See Documentation/filesystems/tmpfs.txt for more information. + +What is rootfs? +--------------- + +Rootfs is a special instance of ramfs, which is always present in 2.6 systems. +(It's used internally as the starting and stopping point for searches of the +kernel's doubly-linked list of mount points.) + +Most systems just mount another filesystem over it and ignore it. The +amount of space an empty instance of ramfs takes up is tiny. + +What is initramfs? +------------------ + +All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is +extracted into rootfs when the kernel boots up. After extracting, the kernel +checks to see if rootfs contains a file "init", and if so it executes it as PID +1. If found, this init process is responsible for bringing the system the +rest of the way up, including locating and mounting the real root device (if +any). If rootfs does not contain an init program after the embedded cpio +archive is extracted into it, the kernel will fall through to the older code +to locate and mount a root partition, then exec some variant of /sbin/init +out of that. + +All this differs from the old initrd in several ways: + + - The old initrd was a separate file, while the initramfs archive is linked + into the linux kernel image. (The directory linux-*/usr is devoted to + generating this archive during the build.) + + - The old initrd file was a gzipped filesystem image (in some file format, + such as ext2, that had to be built into the kernel), while the new + initramfs archive is a gzipped cpio archive (like tar only simpler, + see cpio(1) and Documentation/early-userspace/buffer-format.txt). + + - The program run by the old initrd (which was called /initrd, not /init) did + some setup and then returned to the kernel, while the init program from + initramfs is not expected to return to the kernel. (If /init needs to hand + off control it can overmount / with a new root device and exec another init + program. See the switch_root utility, below.) + + - When switching another root device, initrd would pivot_root and then + umount the ramdisk. But initramfs is rootfs: you can neither pivot_root + rootfs, nor unmount it. Instead delete everything out of rootfs to + free up the space (find -xdev / -exec rm '{}' ';'), overmount rootfs + with the new root (cd /newmount; mount --move . /; chroot .), attach + stdin/stdout/stderr to the new /dev/console, and exec the new init. + + Since this is a remarkably persnickity process (and involves deleting + commands before you can run them), the klibc package introduced a helper + program (utils/run_init.c) to do all this for you. Most other packages + (such as busybox) have named this command "switch_root". + +Populating initramfs: +--------------------- + +The 2.6 kernel build process always creates a gzipped cpio format initramfs +archive and links it into the resulting kernel binary. By default, this +archive is empty (consuming 134 bytes on x86). The config option +CONFIG_INITRAMFS_SOURCE (for some reason buried under devices->block devices +in menuconfig, and living in usr/Kconfig) can be used to specify a source for +the initramfs archive, which will automatically be incorporated into the +resulting binary. This option can point to an existing gzipped cpio archive, a +directory containing files to be archived, or a text file specification such +as the following example: + + dir /dev 755 0 0 + nod /dev/console 644 0 0 c 5 1 + nod /dev/loop0 644 0 0 b 7 0 + dir /bin 755 1000 1000 + slink /bin/sh busybox 777 0 0 + file /bin/busybox initramfs/busybox 755 0 0 + dir /proc 755 0 0 + dir /sys 755 0 0 + dir /mnt 755 0 0 + file /init initramfs/init.sh 755 0 0 + +One advantage of the text file is that root access is not required to +set permissions or create device nodes in the new archive. (Note that those +two example "file" entries expect to find files named "init.sh" and "busybox" in +a directory called "initramfs", under the linux-2.6.* directory. See +Documentation/early-userspace/README for more details.) + +If you don't already understand what shared libraries, devices, and paths +you need to get a minimal root filesystem up and running, here are some +references: +http://www.tldp.org/HOWTO/Bootdisk-HOWTO/ +http://www.tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html +http://www.linuxfromscratch.org/lfs/view/stable/ + +The "klibc" package (http://www.kernel.org/pub/linux/libs/klibc) is +designed to be a tiny C library to statically link early userspace +code against, along with some related utilities. It is BSD licensed. + +I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net) +myself. These are LGPL and GPL, respectively. + +In theory you could use glibc, but that's not well suited for small embedded +uses like this. (A "hello world" program statically linked against glibc is +over 400k. With uClibc it's 7k. Also note that glibc dlopens libnss to do +name lookups, even when otherwise statically linked.) + +Future directions: +------------------ + +Today (2.6.14), initramfs is always compiled in, but not always used. The +kernel falls back to legacy boot code that is reached only if initramfs does +not contain an /init program. The fallback is legacy code, there to ensure a +smooth transition and allowing early boot functionality to gradually move to +"early userspace" (I.E. initramfs). + +The move to early userspace is necessary because finding and mounting the real +root device is complex. Root partitions can span multiple devices (raid or +separate journal). They can be out on the network (requiring dhcp, setting a +specific mac address, logging into a server, etc). They can live on removable +media, with dynamically allocated major/minor numbers and persistent naming +issues requiring a full udev implementation to sort out. They can be +compressed, encrypted, copy-on-write, loopback mounted, strangely partitioned, +and so on. + +This kind of complexity (which inevitably includes policy) is rightly handled +in userspace. Both klibc and busybox/uClibc are working on simple initramfs +packages to drop into a kernel build, and when standard solutions are ready +and widely deployed, the kernel's legacy early boot code will become obsolete +and a candidate for the feature removal schedule. + +But that's a while off yet. diff --git a/Documentation/filesystems/vfs.txt b/Documentation/filesystems/vfs.txt index f042c12e0ed2..ee4c0a8b8db7 100644 --- a/Documentation/filesystems/vfs.txt +++ b/Documentation/filesystems/vfs.txt @@ -3,7 +3,7 @@ Original author: Richard Gooch - Last updated on August 25, 2005 + Last updated on October 28, 2005 Copyright (C) 1999 Richard Gooch Copyright (C) 2005 Pekka Enberg @@ -11,62 +11,61 @@ This file is released under the GPLv2. -What is it? -=========== +Introduction +============ -The Virtual File System (otherwise known as the Virtual Filesystem -Switch) is the software layer in the kernel that provides the -filesystem interface to userspace programs.

This allows safe lock-free - walking of the hash chains, but a matched dentry may have - been partially torn down. The checking of DCACHE_UNHASHED - flag with d_lock held detects such dentries and prevents - them from being returned from look-up. - - -Maintaining POSIX rename semantics -================================== - -Since look-up of dentries is lock-free, it can race against -a concurrent rename operation. For example, during rename -of file A to B, look-up of either A or B must succeed. -So, if look-up of B happens after A has been removed from the -hash chain but not added to the new hash chain, it may fail. -Also, a comparison while the name is being written concurrently -by a rename may result in false positive matches violating -rename semantics. Issues related to race with rename are -handled as described below : - -1. Look-up can be done in two ways - d_lookup() which is safe - from simultaneous renames and __d_lookup() which is not. - If __d_lookup() fails, it must be followed up by a d_lookup() - to correctly determine whether a dentry is in the hash table - or not. d_lookup() protects look-ups using a sequence - lock (rename_lock). - -2. The name associated with a dentry (d_name) may be changed if - a rename is allowed to happen simultaneously. To avoid memcmp() - in __d_lookup() go out of bounds due to a rename and false - positive comparison, the name comparison is done while holding the - per-dentry lock. This prevents concurrent renames during this - operation. - -3. Hash table walking during look-up may move to a different bucket as - the current dentry is moved to a different bucket due to rename. - But we use hlists in dcache hash table and they are null-terminated. - So, even if a dentry moves to a different bucket, hash chain - walk will terminate. [with a list_head list, it may not since - termination is when the list_head in the original bucket is reached]. - Since we redo the d_parent check and compare name while holding - d_lock, lock-free look-up will not race against d_move(). - -4. There can be a theoretical race when a dentry keeps coming back - to original bucket due to double moves. Due to this look-up may - consider that it has never moved and can end up in a infinite loop. - But this is not any worse that theoretical livelocks we already - have in the kernel. - - -Important guidelines for filesystem developers related to dcache_rcu -==================================================================== - -1. Existing dcache interfaces (pre-2.5.62) exported to filesystem - don't change. Only dcache internal implementation changes. However - filesystems *must not* delete from the dentry hash chains directly - using the list macros like allowed earlier. They must use dcache - APIs like d_drop() or __d_drop() depending on the situation. - -2. d_flags is now protected by a per-dentry lock (d_lock). All - access to d_flags must be protected by it. - -3. For a hashed dentry, checking of d_count needs to be protected - by d_lock. - - -Papers and other documentation on dcache locking -================================================ - -1.

And mark some part + of its namespace as slave + + mount --make-rslave /myprivatetree + + Hence forth any mounts within the /myprivatetree done by the + process will not show up in any other namespace. However mounts + done in the parent namespace under /myprivatetree still shows + up in the process's namespace. + + + Apart from the above semantics this feature provides the + building blocks to solve the following problems: + + C) Per-user namespace + + The above semantics allows a way to share mounts across + namespaces. But namespaces are associated with processes. If + namespaces are made first class objects with user API to + associate/disassociate a namespace with userid, then each user + could have his/her own namespace and tailor it to his/her + requirements. Offcourse its needs support from PAM. + + D) Versioned files + + If the entire mount tree is visible at multiple locations, then + a underlying versioning file system can return different + version of the file depending on the path used to access that + file. + + An example is: + + mount --make-shared / + mount --rbind / /view/v1 + mount --rbind / /view/v2 + mount --rbind / /view/v3 + mount --rbind / /view/v4 + + and if /usr has a versioning filesystem mounted, than that + mount appears at /view/v1/usr, /view/v2/usr, /view/v3/usr and + /view/v4/usr too + + A user can request v3 version of the file /usr/fs/namespace.c + by accessing /view/v3/usr/fs/namespace.c . The underlying + versioning filesystem can then decipher that v3 version of the + filesystem is being requested and return the corresponding + inode. + +5) Detailed semantics: +------------------- + The section below explains the detailed semantics of + bind, rbind, move, mount, umount and clone-namespace operations. + + Note: the word 'vfsmount' and the noun 'mount' have been used + to mean the same thing, throughout this document. + +5a) Mount states + + A given mount can be in one of the following states + 1) shared + 2) slave + 3) shared and slave + 4) private + 5) unbindable + + A 'propagation event' is defined as event generated on a vfsmount + that leads to mount or unmount actions in other vfsmounts. + + A 'peer group' is defined as a group of vfsmounts that propagate + events to each other. + + (1) Shared mounts + + A 'shared mount' is defined as a vfsmount that belongs to a + 'peer group'. + + For example: + mount --make-shared /mnt + mount --bin /mnt /tmp + + The mount at /mnt and that at /tmp are both shared and belong + to the same peer group. Anything mounted or unmounted under + /mnt or /tmp reflect in all the other mounts of its peer + group. + + + (2) Slave mounts + + A 'slave mount' is defined as a vfsmount that receives + propagation events and does not forward propagation events. + + A slave mount as the name implies has a master mount from which + mount/unmount events are received. Events do not propagate from + the slave mount to the master. Only a shared mount can be made + a slave by executing the following command + + mount --make-slave mount + + A shared mount that is made as a slave is no more shared unless + modified to become shared. + + (3) Shared and Slave + + A vfsmount can be both shared as well as slave. This state + indicates that the mount is a slave of some vfsmount, and + has its own peer group too. This vfsmount receives propagation + events from its master vfsmount, and also forwards propagation + events to its 'peer group' and to its slave vfsmounts. + + Strictly speaking, the vfsmount is shared having its own + peer group, and this peer-group is a slave of some other + peer group. + + Only a slave vfsmount can be made as 'shared and slave' by + either executing the following command + mount --make-shared mount + or by moving the slave vfsmount under a shared vfsmount. + + (4) Private mount + + A 'private mount' is defined as vfsmount that does not + receive or forward any propagation events. + + (5) Unbindable mount + + A 'unbindable mount' is defined as vfsmount that does not + receive or forward any propagation events and cannot + be bind mounted. + + + State diagram: + The state diagram below explains the state transition of a mount, + in response to various commands. + ------------------------------------------------------------------------ + | |make-shared | make-slave | make-private |make-unbindab| + --------------|------------|--------------|--------------|-------------| + |shared |shared |*slave/private| private | unbindable | + | | | | | | + |-------------|------------|--------------|--------------|-------------| + |slave |shared | **slave | private | unbindable | + | |and slave | | | | + |-------------|------------|--------------|--------------|-------------| + |shared |shared | slave | private | unbindable | + |and slave |and slave | | | | + |-------------|------------|--------------|--------------|-------------| + |private |shared | **private | private | unbindable | + |-------------|------------|--------------|--------------|-------------| + |unbindable |shared |**unbindable | private | unbindable | + ------------------------------------------------------------------------ + + * if the shared mount is the only mount in its peer group, making it + slave, makes it private automatically.

The table + below is a quick reference. + --------------------------------------------------------------------------- + | MOVE MOUNT OPERATION | + |************************************************************************** + | source(A)->| shared | private | slave | unbindable | + | dest(B) | | | | | + | | | | | | | + | v | | | | | + |************************************************************************** + | shared | shared | shared |shared and slave| invalid | + | | | | | | + |non-shared| shared | private | slave | unbindable | + *************************************************************************** + NOTE: moving a mount residing under a shared mount is invalid. + + Details follow: + + 1. 'A' is a shared mount and 'B' is a shared mount. The mount 'A' is + mounted on mount 'B' at dentry 'b'. Also new mounts 'A1', 'A2'...'An' + are created and mounted at dentry 'b' on all mounts that receive + propagation from mount 'B'. A new propagation tree is created in the + exact same configuration as that of 'B'. This new propagation tree + contains all the new mounts 'A1', 'A2'... 'An'. And this new + propagation tree is appended to the already existing propagation tree + of 'A'. + + 2. 'A' is a private mount and 'B' is a shared mount. The mount 'A' is + mounted on mount 'B' at dentry 'b'. Also new mount 'A1', 'A2'... 'An' + are created and mounted at dentry 'b' on all mounts that receive + propagation from mount 'B'. The mount 'A' becomes a shared mount and a + propagation tree is created which is identical to that of + 'B'. This new propagation tree contains all the new mounts 'A1', + 'A2'... 'An'. + + 3. 'A' is a slave mount of mount 'Z' and 'B' is a shared mount. The + mount 'A' is mounted on mount 'B' at dentry 'b'. Also new mounts 'A1', + 'A2'... 'An' are created and mounted at dentry 'b' on all mounts that + receive propagation from mount 'B'. A new propagation tree is created + in the exact same configuration as that of 'B'. This new propagation + tree contains all the new mounts 'A1', 'A2'... 'An'. And this new + propagation tree is appended to the already existing propagation tree of + 'A'. Mount 'A' continues to be the slave mount of 'Z' but it also + becomes 'shared'. + + 4. 'A' is a unbindable mount and 'B' is a shared mount. The operation + is invalid. Because mounting anything on the shared mount 'B' can + create new mounts that get mounted on the mounts that receive + propagation from 'B'. And since the mount 'A' is unbindable, cloning + it to mount at other mountpoints is not possible. + + 5. 'A' is a private mount and 'B' is a non-shared(private or slave or + unbindable) mount. The mount 'A' is mounted on mount 'B' at dentry 'b'. + + 6. 'A' is a shared mount and 'B' is a non-shared mount. The mount 'A' + is mounted on mount 'B' at dentry 'b'. Mount 'A' continues to be a + shared mount. + + 7. 'A' is a slave mount of mount 'Z' and 'B' is a non-shared mount. + The mount 'A' is mounted on mount 'B' at dentry 'b'. Mount 'A' + continues to be a slave mount of mount 'Z'. + + 8. 'A' is a unbindable mount and 'B' is a non-shared mount. The mount + 'A' is mounted on mount 'B' at dentry 'b'. Mount 'A' continues to be a + unbindable mount. + +5e) Mount semantics + + Consider the following command + + mount device B/b + + 'B' is the destination mount and 'b' is the dentry in the destination + mount. + + The above operation is the same as bind operation with the exception + that the source mount is always a private mount. + + +5f) Unmount semantics + + Consider the following command + + umount A + + where 'A' is a mount mounted on mount 'B' at dentry 'b'. + + If mount 'B' is shared, then all most-recently-mounted mounts at dentry + 'b' on mounts that receive propagation from mount 'B' and does not have + sub-mounts within them are unmounted. + + Example: Lets say 'B1', 'B2', 'B3' are shared mounts that propagate to + each other. + + lets say 'A1', 'A2', 'A3' are first mounted at dentry 'b' on mount + 'B1', 'B2' and 'B3' respectively. + + lets say 'C1', 'C2', 'C3' are next mounted at the same dentry 'b' on + mount 'B1', 'B2' and 'B3' respectively. + + if 'C1' is unmounted, all the mounts that are most-recently-mounted on + 'B1' and on the mounts that 'B1' propagates-to are unmounted. + + 'B1' propagates to 'B2' and 'B3'. And the most recently mounted mount + on 'B2' at dentry 'b' is 'C2', and that of mount 'B3' is 'C3'. + + So all 'C1', 'C2' and 'C3' should be unmounted. + + If any of 'C2' or 'C3' has some child mounts, then that mount is not + unmounted, but all other mounts are unmounted. However if 'C1' is told + to be unmounted and 'C1' has some sub-mounts, the umount operation is + failed entirely. + +5g) Clone Namespace + + A cloned namespace contains all the mounts as that of the parent + namespace. + + Lets say 'A' and 'B' are the corresponding mounts in the parent and the + child namespace. + + If 'A' is shared, then 'B' is also shared and 'A' and 'B' propagate to + each other. + + If 'A' is a slave mount of 'Z', then 'B' is also the slave mount of + 'Z'. + + If 'A' is a private mount, then 'B' is a private mount too. + + If 'A' is unbindable mount, then 'B' is a unbindable mount too. + + +6) Quiz + + A.

Why is bind mount needed? How is it different from symbolic links? + symbolic links can get stale if the destination mount gets + unmounted or moved. Bind mounts continue to exist even if the + other mount is unmounted or moved. + + Q2. Why can't the shared subtree be implemented using exportfs? + + exportfs is a heavyweight way of accomplishing part of what + shared subtree can do. I cannot imagine a way to implement the + semantics of slave mount using exportfs? + + Q3 Why is unbindable mount needed? + + Lets say we want to replicate the mount tree at multiple + locations within the same subtree. + + if one rbind mounts a tree within the same subtree 'n' times + the number of mounts created is an exponential function of 'n'. + Having unbindable mount can help prune the unneeded bind + mounts.

And this tree has way more + mounts than what we really needed in the first place. + + One could use a series of umount at each step to prune + out the unneeded mounts. But there is a better solution. + Unclonable mounts come in handy here. + + step 1: + lets say the root tree has just two directories with + one vfsmount. + root + / \ + tmp usr + + How do we set up the same tree at multiple locations under + /root/tmp + + step2: + mount --bind /root/tmp /root/tmp + + mount --make-rshared /root + mount --make-unbindable /root/tmp + + mkdir -p /tmp/m1 + + mount --rbind /root /tmp/m1 + + the new tree now looks like this: + + root + / \ + tmp usr + / + m1 + / \ + tmp usr + + step3: + mkdir -p /tmp/m2 + mount --rbind /root /tmp/m2 + + the new tree now looks like this: + + root + / \ + tmp usr + / \ + m1 m2 + / \ / \ + tmp usr tmp usr + + step4: + + mkdir -p /tmp/m3 + mount --rbind /root /tmp/m3 + + the new tree now looks like this: + + root + / \ + tmp usr + / \ \ + m1 m2 m3 + / \ / \ / \ + tmp usr tmp usr tmp usr + +8) Implementation + +8A) Datastructure + + 4 new fields are introduced to struct vfsmount + ->mnt_share + ->mnt_slave_list + ->mnt_slave + ->mnt_master + + ->mnt_share links togather all the mount to/from which this vfsmount + send/receives propagation events. + + ->mnt_slave_list links all the mounts to which this vfsmount propagates + to. + + ->mnt_slave links togather all the slaves that its master vfsmount + propagates to. + + ->mnt_master points to the master vfsmount from which this vfsmount + receives propagation. + + ->mnt_flags takes two more flags to indicate the propagation status of + the vfsmount.
