Brown <neilb@suse.de> ++ ++Overlay Filesystem ++================== ++ ++This document describes a prototype for a new approach to providing ++overlay-filesystem functionality in Linux (sometimes referred to as ++union-filesystems). An overlay-filesystem tries to present a ++filesystem which is the result over overlaying one filesystem on top ++of the other. ++ ++The result will inevitably fail to look exactly like a normal ++filesystem for various technical reasons. The expectation is that ++many use cases will be able to ignore these differences. ++ ++This approach is 'hybrid' because the objects that appear in the ++filesystem do not all appear to belong to that filesystem. In many ++cases an object accessed in the union will be indistinguishable ++from accessing the corresponding object from the original filesystem. ++This is most obvious from the 'st_dev' field returned by stat(2). ++ ++While directories will report an st_dev from the overlay-filesystem, ++all non-directory objects will report an st_dev from the lower or ++upper filesystem that is providing the object. Similarly st_ino will ++only be unique when combined with st_dev, and both of these can change ++over the lifetime of a non-directory object. Many applications and ++tools ignore these values and will not be affected. ++ ++Upper and Lower ++--------------- ++ ++An overlay filesystem combines two filesystems - an 'upper' filesystem ++and a 'lower' filesystem. When a name exists in both filesystems, the ++object in the 'upper' filesystem is visible while the object in the ++'lower' filesystem is either hidden or, in the case of directories, ++merged with the 'upper' object. ++ ++It would be more correct to refer to an upper and lower 'directory ++tree' rather than 'filesystem' as it is quite possible for both ++directory trees to be in the same filesystem and there is no ++requirement that the root of a filesystem be given for either upper or ++lower. ++ ++The lower filesystem can be any filesystem supported by Linux and does ++not need to be writable. The lower filesystem can even be another ++overlayfs. The upper filesystem will normally be writable and if it ++is it must support the creation of trusted.* extended attributes, and ++must provide valid d_type in readdir responses, at least for symbolic ++links - so NFS is not suitable. ++ ++A read-only overlay of two read-only filesystems may use any ++filesystem type. ++ ++Directories ++----------- ++ ++Overlaying mainly involves directories. If a given name appears in both ++upper and lower filesystems and refers to a non-directory in either, ++then the lower object is hidden - the name refers only to the upper ++object. ++ ++Where both upper and lower objects are directories, a merged directory ++is formed. ++ ++At mount time, the two directories given as mount options are combined ++into a merged directory: ++ ++ mount -t overlayfs overlayfs -olowerdir=/lower,upperdir=/upper /overlay ++ ++Then whenever a lookup is requested in such a merged directory, the ++lookup is performed in each actual directory and the combined result ++is cached in the dentry belonging to the overlay filesystem. If both ++actual lookups find directories, both are stored and a merged ++directory is created, otherwise only one is stored: the upper if it ++exists, else the lower. ++ ++Only the lists of names from directories are merged. Other content ++such as metadata and extended attributes are reported for the upper ++directory only. These attributes of the lower directory are hidden. ++ ++whiteouts and opaque directories ++-------------------------------- ++ ++In order to support rm and rmdir without changing the lower ++filesystem, an overlay filesystem needs to record in the upper filesystem ++that files have been removed. This is done using whiteouts and opaque ++directories (non-directories are always opaque). ++ ++The overlay filesystem uses extended attributes with a ++"trusted.overlay." prefix to record these details. ++ ++A whiteout is created as a symbolic link with target ++"(overlay-whiteout)" and with xattr "trusted.overlay.whiteout" set to "y". ++When a whiteout is found in the upper level of a merged directory, any ++matching name in the lower level is ignored, and the whiteout itself ++is also hidden. ++ ++A directory is made opaque by setting the xattr "trusted.overlay.opaque" ++to "y". Where the upper filesystem contains an opaque directory, any ++directory in the lower filesystem with the same name is ignored. ++ ++readdir ++------- ++ ++When a 'readdir' request is made on a merged directory, the upper and ++lower directories are each read and the name lists merged in the ++obvious way (upper is read first, then lower - entries that already ++exist are not re-added). This merged name list is cached in the ++'struct file' and so remains as long as the file is kept open. If the ++directory is opened and read by two processes at the same time, they ++will each have separate caches. A seekdir to the start of the ++directory (offset 0) followed by a readdir will cause the cache to be ++discarded and rebuilt. ++ ++This means that changes to the merged directory do not appear while a ++directory is being read. This is unlikely to be noticed by many ++programs. ++ ++seek offsets are assigned sequentially when the directories are read. ++Thus if ++ - read part of a directory ++ - remember an offset, and close the directory ++ - re-open the directory some time later ++ - seek to the remembered offset ++ ++there may be little correlation between the old and new locations in ++the list of filenames, particularly if anything has changed in the ++directory. ++ ++Readdir on directories that are not merged is simply handled by the ++underlying directory (upper or lower). ++ ++ ++Non-directories ++--------------- ++ ++Objects that are not directories (files, symlinks, device-special ++files etc.) are presented either from the upper or lower filesystem as ++appropriate. When a file in the lower filesystem is accessed in a way ++the requires write-access, such as opening for write access, changing ++some metadata etc., the file is first copied from the lower filesystem ++to the upper filesystem (copy_up). Note that creating a hard-link ++also requires copy_up, though of course creation of a symlink does ++not. ++ ++The copy_up may turn out to be unnecessary, for example if the file is ++opened for read-write but the data is not modified. ++ ++The copy_up process first makes sure that the containing directory ++exists in the upper filesystem - creating it and any parents as ++necessary. It then creates the object with the same metadata (owner, ++mode, mtime, symlink-target etc.) and then if the object is a file, the ++data is copied from the lower to the upper filesystem. Finally any ++extended attributes are copied up. ++ ++Once the copy_up is complete, the overlay filesystem simply ++provides direct access to the newly created file in the upper ++filesystem - future operations on the file are barely noticed by the ++overlay filesystem (though an operation on the name of the file such as ++rename or unlink will of course be noticed and handled). ++ ++ ++Non-standard behavior ++--------------------- ++ ++The copy_up operation essentially creates a new, identical file and ++moves it over to the old name. The new file may be on a different ++filesystem, so both st_dev and st_ino of the file may change. ++ ++Any open files referring to this inode will access the old data and ++metadata. Similarly any file locks obtained before copy_up will not ++apply to the copied up file. ++ ++On a file opened with O_RDONLY fchmod(2), fchown(2), futimesat(2) and ++fsetxattr(2) will fail with EROFS. ++ ++If a file with multiple hard links is copied up, then this will ++"break" the link. Changes will not be propagated to other names ++referring to the same inode. ++ ++Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory ++object in overlayfs will not contain valid absolute paths, only ++relative paths leading up to the filesystem's root. This will be ++fixed in the future. ++ ++Some operations are not atomic, for example a crash during copy_up or ++rename will leave the filesystem in an inconsistent state. This will ++be addressed in the future. ++ ++Changes to underlying filesystems ++--------------------------------- ++ ++Offline changes, when the overlay is not mounted, are allowed to either ++the upper or the lower trees. ++ ++Changes to the underlying filesystems while part of a mounted overlay ++filesystem are not allowed. If the underlying filesystem is changed, ++the behavior of the overlay is undefined, though it will not result in ++a crash or deadlock. +--- a/Documentation/filesystems/vfs.txt ++++ b/Documentation/filesystems/vfs.txt +@@ -363,6 +363,7 @@ struct inode_operations { + int (*atomic_open)(struct inode *, struct dentry *, + struct file *, unsigned open_flag, + umode_t create_mode, int *opened); ++ int (*dentry_open)(struct dentry *, struct file *, const struct cred *); + }; + + Again, all methods are called without any locks being held, unless +@@ -692,6 +693,12 @@ struct address_space_operations { + but instead uses bmap to find out where the blocks in the file + are and uses those addresses directly. + ++ dentry_open: this is an alternative to f_op->open(), the difference is that ++ this method may open a file not necessarily originating from the same ++ filesystem as the one i_op->open() was called on.

The ++ * "next" pointer of the last BRANCH in a choice points to the ++ * thing following the whole choice. This is also where the ++ * final "next" pointer of each individual branch points; each ++ * branch starts with the operand node of a BRANCH node. ++ * ++ * BACK Normal "next" pointers all implicitly point forward; BACK ++ * exists to make loop structures possible. ++ * ++ * STAR,PLUS '?', and complex '*' and '+', are implemented as circular ++ * BRANCH structures using BACK.

This is most useful only for embedded machines ++with MMC/SD devices statically connected to the platform GPIO bus. ++ ++The data structures are declared in <linux/mmc/gpiommc.h>. ++ ++To register a new device, define an instance of struct gpiommc_platform_data. ++This structure holds any information about how the device is hooked up to the ++GPIO pins and what hardware modes the device supports. See the docbook-style ++documentation in the header file for more information on the struct fields. ++ ++Then allocate a new instance of a platform device by doing: ++ ++ pdev = platform_device_alloc(GPIOMMC_PLATDEV_NAME, gpiommc_next_id()); ++ ++This will allocate the platform device data structures and hook it up to the ++gpiommc driver. ++Then add the gpiommc_platform_data to the platform device. ++ ++ err = platform_device_add_data(pdev, pdata, sizeof(struct gpiommc_platform_data)); ++ ++You may free the local instance of struct gpiommc_platform_data now.

The gpiommc probe routine will be invoked now and you should see a kernel ++log message for the added device. ++ ++ ++Registering devices via configfs ++================================ ++ ++MMC/SD cards connected via GPIO often are a pretty dynamic thing, as for example ++selfmade hacks for soldering an MMC/SD card to standard GPIO pins on embedded ++hardware are a common situation. ++So we provide a dynamic interface to conveniently handle adding and removing ++devices from userspace, without the need to recompile the kernel. ++ ++The "gpiommc" subdirectory at the configfs mountpoint is used for handling ++the dynamic configuration. ++ ++To create a new device, it must first be allocated with mkdir. ++The following command will allocate a device named "my_mmc": ++ mkdir /config/gpiommc/my_mmc ++ ++There are several configuration files available in the new ++/config/gpiommc/my_mmc/ directory: ++ ++gpio_data_in = The SPI data-IN GPIO pin number. ++gpio_data_out = The SPI data-OUT GPIO pin number. ++gpio_clock = The SPI Clock GPIO pin number. ++gpio_chipselect = The SPI Chipselect GPIO pin number. ++gpio_chipselect_activelow = Boolean. If 0, Chipselect is active-HIGH. ++ If 1, Chipselect is active-LOW. ++spi_mode = The SPI data mode. Can be 0-3. ++spi_delay = Enable all delays in the lowlevel bitbanging. ++max_bus_speed = The maximum SPI bus speed. In Hertz. ++ ++register = Not a configuration parameter. ++ Used to register the configured card ++ with the kernel. ++ ++The device must first get configured and then registered by writing "1" to ++the "register" file. ++The configuration parameters "gpio_data_in", "gpio_data_out", "gpio_clock" ++and "gpio_chipselect" are essential and _must_ be configured before writing ++"1" to the "register" file. The registration will fail, otherwise. ++ ++The default values for the other parameters are: ++gpio_chipselect_activelow = 1 (CS active-LOW) ++spi_mode = 0 (SPI_MODE_0) ++spi_delay = 1 (enabled) ++max_bus_speed = 5000000 (5 Mhz) ++ ++Configuration values can not be changed after registration.
