## littlefs for RT-Thread
|
||||||
|
|
||||||
|
A little fail-safe filesystem designed for microcontrollers.
|
||||||
|
|
||||||
|
```
|
||||||
|
| | | .---._____
|
||||||
|
.-----. | |
|
||||||
|
--|o |---| littlefs |
|
||||||
|
--| |---| |
|
||||||
|
'-----' '----------'
|
||||||
|
| | |
|
||||||
|
```
|
||||||
|
|
||||||
|
**Power-loss resilience** - littlefs is designed to handle random power
|
||||||
|
failures. All file operations have strong copy-on-write guarantees and if
|
||||||
|
power is lost the filesystem will fall back to the last known good state.
|
||||||
|
|
||||||
|
**Dynamic wear leveling** - littlefs is designed with flash in mind, and
|
||||||
|
provides wear leveling over dynamic blocks. Additionally, littlefs can
|
||||||
|
detect bad blocks and work around them.
|
||||||
|
|
||||||
|
**Bounded RAM/ROM** - littlefs is designed to work with a small amount of
|
||||||
|
memory. RAM usage is strictly bounded, which means RAM consumption does not
|
||||||
|
change as the filesystem grows. The filesystem contains no unbounded
|
||||||
|
recursion and dynamic memory is limited to configurable buffers that can be
|
||||||
|
provided statically.
|
||||||
|
|
||||||
|
## Example
|
||||||
|
|
||||||
|
Here's a simple example that updates a file named `boot_count` every time
|
||||||
|
main runs. The program can be interrupted at any time without losing track
|
||||||
|
of how many times it has been booted and without corrupting the filesystem:
|
||||||
|
|
||||||
|
``` c
|
||||||
|
#include "lfs.h"
|
||||||
|
|
||||||
|
// variables used by the filesystem
|
||||||
|
lfs_t lfs;
|
||||||
|
lfs_file_t file;
|
||||||
|
|
||||||
|
// configuration of the filesystem is provided by this struct
|
||||||
|
const struct lfs_config cfg = {
|
||||||
|
// block device operations
|
||||||
|
.read = user_provided_block_device_read,
|
||||||
|
.prog = user_provided_block_device_prog,
|
||||||
|
.erase = user_provided_block_device_erase,
|
||||||
|
.sync = user_provided_block_device_sync,
|
||||||
|
|
||||||
|
// block device configuration
|
||||||
|
.read_size = 16,
|
||||||
|
.prog_size = 16,
|
||||||
|
.block_size = 4096,
|
||||||
|
.block_count = 128,
|
||||||
|
.cache_size = 16,
|
||||||
|
.lookahead_size = 16,
|
||||||
|
.block_cycles = 500,
|
||||||
|
};
|
||||||
|
|
||||||
|
// entry point
|
||||||
|
int main(void) {
|
||||||
|
// mount the filesystem
|
||||||
|
int err = lfs_mount(&lfs, &cfg);
|
||||||
|
|
||||||
|
// reformat if we can't mount the filesystem
|
||||||
|
// this should only happen on the first boot
|
||||||
|
if (err) {
|
||||||
|
lfs_format(&lfs, &cfg);
|
||||||
|
lfs_mount(&lfs, &cfg);
|
||||||
|
}
|
||||||
|
|
||||||
|
// read current count
|
||||||
|
uint32_t boot_count = 0;
|
||||||
|
lfs_file_open(&lfs, &file, "boot_count", LFS_O_RDWR | LFS_O_CREAT);
|
||||||
|
lfs_file_read(&lfs, &file, &boot_count, sizeof(boot_count));
|
||||||
|
|
||||||
|
// update boot count
|
||||||
|
boot_count += 1;
|
||||||
|
lfs_file_rewind(&lfs, &file);
|
||||||
|
lfs_file_write(&lfs, &file, &boot_count, sizeof(boot_count));
|
||||||
|
|
||||||
|
// remember the storage is not updated until the file is closed successfully
|
||||||
|
lfs_file_close(&lfs, &file);
|
||||||
|
|
||||||
|
// release any resources we were using
|
||||||
|
lfs_unmount(&lfs);
|
||||||
|
|
||||||
|
// print the boot count
|
||||||
|
printf("boot_count: %d\n", boot_count);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
Detailed documentation (or at least as much detail as is currently available)
|
||||||
|
can be found in the comments in [lfs.h](lfs.h).
|
||||||
|
|
||||||
|
littlefs takes in a configuration structure that defines how the filesystem
|
||||||
|
operates. The configuration struct provides the filesystem with the block
|
||||||
|
device operations and dimensions, tweakable parameters that tradeoff memory
|
||||||
|
usage for performance, and optional static buffers if the user wants to avoid
|
||||||
|
dynamic memory.
|
||||||
|
|
||||||
|
The state of the littlefs is stored in the `lfs_t` type which is left up
|
||||||
|
to the user to allocate, allowing multiple filesystems to be in use
|
||||||
|
simultaneously. With the `lfs_t` and configuration struct, a user can
|
||||||
|
format a block device or mount the filesystem.
|
||||||
|
|
||||||
|
Once mounted, the littlefs provides a full set of POSIX-like file and
|
||||||
|
directory functions, with the deviation that the allocation of filesystem
|
||||||
|
structures must be provided by the user.
|
||||||
|
|
||||||
|
All POSIX operations, such as remove and rename, are atomic, even in event
|
||||||
|
of power-loss. Additionally, file updates are not actually committed to
|
||||||
|
the filesystem until sync or close is called on the file.
|
||||||
|
|
||||||
|
## Other notes
|
||||||
|
|
||||||
|
Littlefs is written in C, and specifically should compile with any compiler
|
||||||
|
that conforms to the `C99` standard.
|
||||||
|
|
||||||
|
All littlefs calls have the potential to return a negative error code. The
|
||||||
|
errors can be either one of those found in the `enum lfs_error` in
|
||||||
|
[lfs.h](lfs.h), or an error returned by the user's block device operations.
|
||||||
|
|
||||||
|
In the configuration struct, the `prog` and `erase` function provided by the
|
||||||
|
user may return a `LFS_ERR_CORRUPT` error if the implementation already can
|
||||||
|
detect corrupt blocks. However, the wear leveling does not depend on the return
|
||||||
|
code of these functions, instead all data is read back and checked for
|
||||||
|
integrity.
|
||||||
|
|
||||||
|
If your storage caches writes, make sure that the provided `sync` function
|
||||||
|
flushes all the data to memory and ensures that the next read fetches the data
|
||||||
|
from memory, otherwise data integrity can not be guaranteed. If the `write`
|
||||||
|
function does not perform caching, and therefore each `read` or `write` call
|
||||||
|
hits the memory, the `sync` function can simply return 0.
|
||||||
|
|
||||||
|
## Design
|
||||||
|
|
||||||
|
At a high level, littlefs is a block based filesystem that uses small logs to
|
||||||
|
store metadata and larger copy-on-write (COW) structures to store file data.
|
||||||
|
|
||||||
|
In littlefs, these ingredients form a sort of two-layered cake, with the small
|
||||||
|
logs (called metadata pairs) providing fast updates to metadata anywhere on
|
||||||
|
storage, while the COW structures store file data compactly and without any
|
||||||
|
wear amplification cost.
|
||||||
|
|
||||||
|
Both of these data structures are built out of blocks, which are fed by a
|
||||||
|
common block allocator. By limiting the number of erases allowed on a block
|
||||||
|
per allocation, the allocator provides dynamic wear leveling over the entire
|
||||||
|
filesystem.

|
||||||
|
[SPEC.md](SPEC.md).
|
||||||
|
|
||||||
|
- [DESIGN.md](DESIGN.md) - A fully detailed dive into how littlefs works.
|
||||||
|
I would suggest reading it as the tradeoffs at work are quite interesting.
|
||||||
|
|
||||||
|
- [SPEC.md](SPEC.md) - The on-disk specification of littlefs with all the
|
||||||
|
nitty-gritty details. May be useful for tooling development.
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
The littlefs comes with a test suite designed to run on a PC using the
|
||||||
|
[emulated block device](bd/lfs_testbd.h) found in the `bd` directory.
|
||||||
|
The tests assume a Linux environment and can be started with make:
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
make test
|
||||||
|
```
|
||||||
|
|
||||||
|
Tests are implemented in C in the .toml files found in the `tests` directory.
|
||||||
|
When developing a feature or fixing a bug, it is frequently useful to run a
|
||||||
|
single test case or suite of tests:
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
./scripts/test.py -l runners/test_runner # list available test suites
|
||||||
|
./scripts/test.py -L runners/test_runner test_dirs # list available test cases
|
||||||
|
./scripts/test.py runners/test_runner test_dirs # run a specific test suite
|
||||||
|
```
|
||||||
|
|
||||||
|
If an assert fails in a test, test.py will try to print information about the
|
||||||
|
failure:
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
tests/test_dirs.toml:1:failure: test_dirs_root:1g12gg2 (PROG_SIZE=16, ERASE_SIZE=512) failed
|
||||||
|
tests/test_dirs.toml:5:assert: assert failed with 0, expected eq 42
|
||||||
|
lfs_mount(&lfs, cfg) => 42;
|
||||||
|
```
|
||||||
|
|
||||||
|
This includes the test id, which can be passed to test.py to run only that
|
||||||
|
specific test permutation:
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
./scripts/test.py runners/test_runner test_dirs_root:1g12gg2 # run a specific test permutation
|
||||||
|
./scripts/test.py runners/test_runner test_dirs_root:1g12gg2 --gdb # drop into gdb on failure
|
||||||
|
```
|
||||||
|
|
||||||
|
Some other flags that may be useful:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./scripts/test.py runners/test_runner -b -j # run tests in parallel
|
||||||
|
./scripts/test.py runners/test_runner -v -O- # redirect stdout to stdout
|
||||||
|
./scripts/test.py runners/test_runner -ddisk # capture resulting disk image
|
||||||
|
```
|
||||||
|
|
||||||
|
See `-h/--help` for a full list of available flags:
|
||||||
|
|
||||||
|
``` bash
|
||||||
|
./scripts/test.py --help
|
||||||
|
```

|
- [SPIFFS] - Another excellent embedded filesystem for NOR flash. As a more
|
||||||
|
traditional logging filesystem with full static wear-leveling, SPIFFS will
|
||||||
|
likely outperform littlefs on small memories such as the internal flash on
|
||||||
|
microcontrollers.
|
||||||
|
|
||||||
|
- [Dhara] - An interesting NAND flash translation layer designed for small
|
||||||
|
MCUs. It offers static wear-leveling and power-resilience with only a fixed
|
||||||
|
_O(|address|)_ pointer structure stored on each block and in RAM.
|
||||||
|
|
||||||
|
- [ChaN's FatFs] - A lightweight reimplementation of the infamous FAT filesystem
|
||||||
|
for microcontroller-scale devices. Due to limitations of FAT it can't provide
|
||||||
|
power-loss resilience, but it does allow easy interop with PCs.

## littlefs technical specification
|
||||||
|
|
||||||
|
This is the technical specification of the little filesystem with on-disk
|
||||||
|
version lfs2.1. This document covers the technical details of how the littlefs
|
||||||
|
is stored on disk for introspection and tooling. This document assumes you are
|
||||||
|
familiar with the design of the littlefs, for more info on how littlefs works
|
||||||
|
check out [DESIGN.md](DESIGN.md).
|
||||||
|
|
||||||
|
```
|
||||||
|
| | | .---._____
|
||||||
|
.-----. | |
|
||||||
|
--|o |---| littlefs |
|
||||||
|
--| |---| |
|
||||||
|
'-----' '----------'
|
||||||
|
| | |
|
||||||
|
```
|
||||||
|
|
||||||
|
## Some quick notes
|
||||||
|
|
||||||
|
- littlefs is a block-based filesystem. The disk is divided into an array of
|
||||||
|
evenly sized blocks that are used as the logical unit of storage.
|
||||||
|
|
||||||
|
- Block pointers are stored in 32 bits, with the special value `0xffffffff`
|
||||||
|
representing a null block address.
|
||||||
|
|
||||||
|
- In addition to the logical block size (which usually matches the erase
|
||||||
|
block size), littlefs also uses a program block size and read block size.
|
||||||
|
These determine the alignment of block device operations, but don't need
|
||||||
|
to be consistent for portability.
|
||||||
|
|
||||||
|
- By default, all values in littlefs are stored in little-endian byte order.
|
||||||
|
|
||||||
|
## Directories / Metadata pairs
|
||||||
|
|
||||||
|
Metadata pairs form the backbone of littlefs and provide a system for
|
||||||
|
distributed atomic updates. Even the superblock is stored in a metadata pair.
|
||||||
|
|
||||||
|
As their name suggests, a metadata pair is stored in two blocks, with one block
|
||||||
|
providing a backup during erase cycles in case power is lost. These two blocks
|
||||||
|
are not necessarily sequential and may be anywhere on disk, so a "pointer" to a
|
||||||
|
metadata pair is stored as two block pointers.
|
||||||
|
|
||||||
|
On top of this, each metadata block behaves as an appendable log, containing a
|
||||||
|
variable number of commits. Commits can be appended to the metadata log in
|
||||||
|
order to update the metadata without requiring an erase cycles. Note that
|
||||||
|
successive commits may supersede the metadata in previous commits. Only the
|
||||||
|
most recent metadata should be considered valid.
|
||||||
|
|
||||||
|
The high-level layout of a metadata block is fairly simple:
|
||||||
|
|
||||||
|
```

|
||||||
|
```
|
||||||
|
|
||||||
|
Each metadata block contains a 32-bit revision count followed by a number of
|
||||||
|
commits. Each commit contains a variable number of metadata entries followed
|
||||||
|
by a 32-bit CRC.
|
||||||
|
|
||||||
|
Note also that entries aren't necessarily word-aligned. This allows us to
|
||||||
|
store metadata more compactly, however we can only write to addresses that are
|
||||||
|
aligned to our program block size. This means each commit may have padding for
|
||||||
|
alignment.
|
||||||
|
|
||||||
|
Metadata block fields:
|
||||||
|
|
||||||
|
1. **Revision count (32-bits)** - Incremented every erase cycle. If both blocks
|
||||||
|
contain valid commits, only the block with the most recent revision count
|
||||||
|
should be used. Sequence comparison must be used to avoid issues with
|
||||||
|
integer overflow.
|
||||||
|
|
||||||
|
2. **CRC (32-bits)** - Detects corruption from power-loss or other write
|
||||||
|
issues. Uses a CRC-32 with a polynomial of `0x04c11db7` initialized
|
||||||
|
with `0xffffffff`.
|
||||||
|
|
||||||
|
Entries themselves are stored as a 32-bit tag followed by a variable length
|
||||||
|
blob of data. But exactly how these tags are stored is a little bit tricky.
|
||||||
|
|
||||||
|
Metadata blocks support both forward and backward iteration. In order to do
|
||||||
|
this without duplicating the space for each tag, neighboring entries have their
|
||||||
|
tags XORed together, starting with `0xffffffff`.
|
||||||
|
|
||||||
|

|

```
|
||||||
|
|
||||||
|
Two things to note before we get into the details around tag encoding:
|
||||||
|
|
||||||
|
1. Each tag contains a valid bit used to indicate if the tag and containing
|
||||||
|
commit is valid. After XORing, this bit should always be zero.
|
||||||
|
|
||||||
|
At the end of each commit, the valid bit of the previous tag is XORed
|
||||||
|
with the lowest bit in the type field of the CRC tag. This allows
|
||||||
|
the CRC tag to force the next commit to fail the valid bit test if it
|
||||||
|
has not yet been written to.
|
||||||
|
|
||||||
|
2. The valid bit alone is not enough info to know if the next commit has been
|
||||||
|
erased. We don't know the order bits will be programmed in a program block,
|
||||||
|
so it's possible that the next commit had an attempted program that left the
|
||||||
|
valid bit unchanged.
|
||||||
|
|
||||||
|
To ensure we only ever program erased bytes, each commit can contain an
|
||||||
|
optional forward-CRC (FCRC). An FCRC contains a checksum of some amount of
|
||||||
|
bytes in the next commit at the time it was erased.
|
||||||
|
|
||||||
|

||||||
|
| |
|
||||||
|
'-------------------'
|
||||||
|
```
|
||||||
|
|
||||||
|
If the FCRC is missing or the checksum does not match, we must assume a
|
||||||
|
commit was attempted but failed due to power-loss.
|
||||||
|
|
||||||
|
Note that end-of-block commits do not need an FCRC.
|
||||||
|
|
||||||
|
## Metadata tags
|
||||||
|
|
||||||
|
So in littlefs, 32-bit tags describe every type of metadata. And this means
|
||||||
|
_every_ type of metadata, including file entries, directory fields, and
|
||||||
|
global state. Even the CRCs used to mark the end of commits get their own tag.
|
||||||
|
|
||||||
|
Because of this, the tag format contains some densely packed information. Note
|
||||||
|
that there are multiple levels of types which break down into more info:
|
||||||
|
|
||||||
|
```
|
||||||
|
[---- 32 ----]
|
||||||
|
[1|-- 11 --|-- 10 --|-- 10 --]
|
||||||
|
^. ^ . ^ ^- length
|
||||||
|
|. | . '------------ id
|
||||||
|
|. '-----.------------------ type (type3)
|
||||||
|
'.-----------.------------------ valid bit
|
||||||
|
[-3-|-- 8 --]
|
||||||
|
^ ^- chunk
|
||||||
|
'------- type (type1)
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
Before we go further, there's one important thing to note. These tags are
|
||||||
|
**not** stored in little-endian. Tags stored in commits are actually stored
|
||||||
|
in big-endian (and is the only thing in littlefs stored in big-endian). This
|
||||||
|
little bit of craziness comes from the fact that the valid bit must be the
|
||||||
|
first bit in a commit, and when converted to little-endian, the valid bit finds
|
||||||
|
itself in byte 4. We could restructure the tag to store the valid bit lower,
|
||||||
|
but, because none of the fields are byte-aligned, this would be more
|
||||||
|
complicated than just storing the tag in big-endian.
|
||||||
|
|
||||||
|
Another thing to note is that both the tags `0x00000000` and `0xffffffff` are
|
||||||
|
invalid and can be used for null values.
|
||||||
|
|
||||||
|
Metadata tag fields:
|
||||||
|
|
||||||
|
1. **Valid bit (1-bit)** - Indicates if the tag is valid.
|
||||||
|
|
||||||
|
2. **Type3 (11-bits)** - Type of the tag. This field is broken down further
|
||||||
|
into a 3-bit abstract type and an 8-bit chunk field. Note that the value
|
||||||
|
`0x000` is invalid and not assigned a type.
|
||||||
|
|
||||||
|
1. **Type1 (3-bits)** - Abstract type of the tag. Groups the tags into
|
||||||
|
8 categories that facilitate bitmasked lookups.
|
||||||
|
|
||||||
|
2. **Chunk (8-bits)** - Chunk field used for various purposes by the different
|
||||||
|
abstract types. type1+chunk+id form a unique identifier for each tag in the
|
||||||
|
metadata block.
|
||||||
|
|
||||||
|
3. **Id (10-bits)** - File id associated with the tag. Each file in a metadata
|
||||||
|
block gets a unique id which is used to associate tags with that file. The
|
||||||
|
special value `0x3ff` is used for any tags that are not associated with a
|
||||||
|
file, such as directory and global metadata.
|
||||||
|
|
||||||
|
4. **Length (10-bits)** - Length of the data in bytes. The special value
|
||||||
|
`0x3ff` indicates that this tag has been deleted.
|
||||||
|
|
||||||
|
## Metadata types
|
||||||
|
|
||||||
|
What follows is an exhaustive list of metadata in littlefs.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x401` LFS_TYPE_CREATE
|
||||||
|
|
||||||
|
Creates a new file with this id. Note that files in a metadata block
|
||||||
|
don't necessarily need a create tag. All a create does is move over any
|
||||||
|
files using this id. In this sense a create is similar to insertion into
|
||||||
|
an imaginary array of files.
|
||||||
|
|
||||||
|
The create and delete tags allow littlefs to keep files in a directory
|
||||||
|
ordered alphabetically by filename.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x4ff` LFS_TYPE_DELETE
|
||||||
|
|
||||||
|
Deletes the file with this id. An inverse to create, this tag moves over
|
||||||
|
any files neighboring this id similar to a deletion from an imaginary
|
||||||
|
array of files.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x0xx` LFS_TYPE_NAME
|
||||||
|
|
||||||
|
Associates the id with a file name and file type.
|
||||||
|
|
||||||
|
The data contains the file name stored as an ASCII string (may be expanded to
|
||||||
|
UTF8 in the future).
|
||||||
|
|
||||||
|
The chunk field in this tag indicates an 8-bit file type which can be one of
|
||||||
|
the following.
|
||||||
|
|
||||||
|
Currently, the name tag must precede any other tags associated with the id and
|
||||||
|
can not be reassigned without deleting the file.

||||||

#### `0x001` LFS_TYPE_REG
|
||||||
|
|
||||||
|
Initializes the id + name as a regular file.
|
||||||
|
|
||||||
|
How each file is stored depends on its struct tag, which is described below.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x002` LFS_TYPE_DIR
|
||||||
|
|
||||||
|
Initializes the id + name as a directory.
|
||||||
|
|
||||||
|
Directories in littlefs are stored on disk as a linked-list of metadata pairs,
|
||||||
|
each pair containing any number of files in alphabetical order. A pointer to
|
||||||
|
the directory is stored in the struct tag, which is described below.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x0ff` LFS_TYPE_SUPERBLOCK
|
||||||
|
|
||||||
|
Initializes the id as a superblock entry.
|
||||||
|
|
||||||
|
The superblock entry is a special entry used to store format-time configuration
|
||||||
|
and identify the filesystem.
|
||||||
|
|
||||||
|
The name is a bit of a misnomer. While the superblock entry serves the same
|
||||||
|
purpose as a superblock found in other filesystems, in littlefs the superblock
|
||||||
|
does not get a dedicated block. Instead, the superblock entry is duplicated
|
||||||
|
across a linked-list of metadata pairs rooted on the blocks 0 and 1. The last
|
||||||
|
metadata pair doubles as the root directory of the filesystem.

||||||

superblock pairs root directory
|
||||||
|
```
|
||||||
|
|
||||||
|
The filesystem starts with only the root directory. The superblock metadata
|
||||||
|
pairs grow every time the root pair is compacted in order to prolong the
|
||||||
|
life of the device exponentially.
|
||||||
|
|
||||||
|
The contents of the superblock entry are stored in a name tag with the
|
||||||
|
superblock type and an inline-struct tag. The name tag contains the magic
|
||||||
|
string "littlefs", while the inline-struct tag contains version and
|
||||||
|
configuration information.

|
|

|
Superblock fields:
|
||||||
|
|
||||||
|
1. **Magic string (8-bytes)** - Magic string indicating the presence of
|
||||||
|
littlefs on the device. Must be the string "littlefs".
|
||||||
|
|
||||||
|
2. **Version (32-bits)** - The version of littlefs at format time. The version
|
||||||
|
is encoded in a 32-bit value with the upper 16-bits containing the major
|
||||||
|
version, and the lower 16-bits containing the minor version.
|
||||||
|
|
||||||
|
This specification describes version 2.0 (`0x00020000`).
|
||||||
|
|
||||||
|
3. **Block size (32-bits)** - Size of the logical block size used by the
|
||||||
|
filesystem in bytes.
|
||||||
|
|
||||||
|
4. **Block count (32-bits)** - Number of blocks in the filesystem.
|
||||||
|
|
||||||
|
5. **Name max (32-bits)** - Maximum size of file names in bytes.
|
||||||
|
|
||||||
|
6. **File max (32-bits)** - Maximum size of files in bytes.
|
||||||
|
|
||||||
|
7. **Attr max (32-bits)** - Maximum size of file attributes in bytes.
|
||||||
|
|
||||||
|
The superblock must always be the first entry (id 0) in the metadata pair, and
|
||||||
|
the name tag must always be the first tag in the metadata pair. This makes it
|
||||||
|
so that the magic string "littlefs" will always reside at offset=8 in a valid
|
||||||
|
littlefs superblock.

#### `0x2xx` LFS_TYPE_STRUCT
|
||||||
|
|
||||||
|
Associates the id with an on-disk data structure.
|
||||||
|
|
||||||
|
The exact layout of the data depends on the data structure type stored in the
|
||||||
|
chunk field and can be one of the following.
|
||||||
|
|
||||||
|
Any type of struct supersedes all other structs associated with the id. For
|
||||||
|
example, appending a ctz-struct replaces an inline-struct on the same file.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x200` LFS_TYPE_DIRSTRUCT
|
||||||
|
|
||||||
|
Gives the id a directory data structure.
|
||||||
|
|
||||||
|
Directories in littlefs are stored on disk as a linked-list of metadata pairs,
|
||||||
|
each pair containing any number of files in alphabetical order.
|
||||||
|
|
||||||
|
```
|
||||||

|
```
|
||||||
|
|
||||||
|
The dir-struct tag contains only the pointer to the first metadata-pair in the
|
||||||
|
directory. The directory size is not known without traversing the directory.
|
||||||
|
|
||||||
|
The pointer to the next metadata-pair in the directory is stored in a tail tag,
|
||||||
|
which is described below.

|
#### `0x201` LFS_TYPE_INLINESTRUCT
|
||||||
|
|
||||||
|
Gives the id an inline data structure.
|
||||||
|
|
||||||
|
Inline structs store small files that can fit in the metadata pair. In this
|
||||||
|
case, the file data is stored directly in the tag's data area.

|
---
|
||||||
|
#### `0x202` LFS_TYPE_CTZSTRUCT
|
||||||
|
|
||||||
|
Gives the id a CTZ skip-list data structure.
|
||||||
|
|
||||||
|
CTZ skip-lists store files that can not fit in the metadata pair. These files
|
||||||
|
are stored in a skip-list in reverse, with a pointer to the head of the
|
||||||
|
skip-list. Note that the head of the skip-list and the file size is enough
|
||||||
|
information to read the file.
|
||||||
|
|
||||||
|
How exactly CTZ skip-lists work is a bit complicated. A full explanation can be
|
||||||
|
found in the [DESIGN.md](DESIGN.md#ctz-skip-lists).
|
||||||
|
|
||||||
|
A quick summary: For every _n_‍th block where _n_ is divisible by
|
||||||
|
2‍_ˣ_, that block contains a pointer to block _n_-2‍_ˣ_.
|
||||||
|
These pointers are stored in increasing order of _x_ in each block of the file
|
||||||
|
before the actual data.
|
||||||
|
|
||||||
|
```
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
Note that the maximum number of pointers in a block is bounded by the maximum
|
||||||
|
file size divided by the block size. With 32 bits for file size, this results
|
||||||
|
in a minimum block size of 104 bytes.

#### `0x3xx` LFS_TYPE_USERATTR
|
||||||
|
|
||||||
|
Attaches a user attribute to an id.
|
||||||
|
|
||||||
|
littlefs has a concept of "user attributes". These are small user-provided
|
||||||
|
attributes that can be used to store things like timestamps, hashes,
|
||||||
|
permissions, etc.
|
||||||
|
|
||||||
|
Each user attribute is uniquely identified by an 8-bit type which is stored in
|
||||||
|
the chunk field, and the user attribute itself can be found in the tag's data.
|
||||||
|
|
||||||
|
There are currently no standard user attributes and a portable littlefs
|
||||||
|
implementation should work with any user attributes missing.

#### `0x6xx` LFS_TYPE_TAIL
|
||||||
|
|
||||||
|
Provides the tail pointer for the metadata pair itself.
|
||||||
|
|
||||||
|
The metadata pair's tail pointer is used in littlefs for a linked-list
|
||||||
|
containing all metadata pairs. The chunk field contains the type of the tail,
|
||||||
|
which indicates if the following metadata pair is a part of the directory
|
||||||
|
(hard-tail) or only used to traverse the filesystem (soft-tail).
|
||||||
|
|
||||||
|
```
|
||||||
|
.--------.
|
||||||
|
.| dir A |-.
|
||||||
|
||softtail| |
|
||||||
|
.--------| |-'
|
||||||
|

|
||||||
|

|

|
|'--------' |'--------' |'--------'
|
||||||
|
'--------' '--------' '--------'
|
||||||
|
```
|
||||||
|
|
||||||
|
Currently any type supersedes any other preceding tails in the metadata pair,
|
||||||
|
but this may change if additional metadata pair state is added.
|
||||||
|
|
||||||
|
A note about the metadata pair linked-list: Normally, this linked-list contains
|
||||||
|
every metadata pair in the filesystem. However, there are some operations that
|
||||||
|
can cause this linked-list to become out of sync if a power-loss were to occur.
|
||||||
|
When this happens, littlefs sets the "sync" flag in the global state. How
|
||||||
|
exactly this flag is stored is described below.
|
||||||
|
|
||||||
|
When the sync flag is set:
|
||||||
|
|
||||||
|
1. The linked-list may contain an orphaned directory that has been removed in
|
||||||
|
the filesystem.
|
||||||
|
2. The linked-list may contain a metadata pair with a bad block that has been
|
||||||
|
replaced in the filesystem.
|
||||||
|
|
||||||
|
If the sync flag is set, the threaded linked-list must be checked for these
|
||||||
|
errors before it can be used reliably. Note that the threaded linked-list can
|
||||||
|
be ignored if littlefs is mounted read-only.
|
||||||
|
|
||||||

#### `0x600` LFS_TYPE_SOFTTAIL
|
||||||
|
|
||||||
|
Provides a tail pointer that points to the next metadata pair in the
|
||||||
|
filesystem.
|
||||||
|
|
||||||
|
In this case, the next metadata pair is not a part of our current directory
|
||||||
|
and should only be followed when traversing the entire filesystem.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x601` LFS_TYPE_HARDTAIL
|
||||||
|
|
||||||
|
Provides a tail pointer that points to the next metadata pair in the
|
||||||
|
directory.
|
||||||
|
|
||||||
|
In this case, the next metadata pair belongs to the current directory. Note
|
||||||
|
that because directories in littlefs are sorted alphabetically, the next
|
||||||
|
metadata pair should only contain filenames greater than any filename in the
|
||||||
|
current pair.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x7xx` LFS_TYPE_GSTATE
|
||||||
|
|
||||||
|
Provides delta bits for global state entries.
|
||||||
|
|
||||||
|
littlefs has a concept of "global state". This is a small set of state that
|
||||||
|
can be updated by a commit to _any_ metadata pair in the filesystem.
|
||||||
|
|
||||||
|
The way this works is that the global state is stored as a set of deltas
|
||||||
|
distributed across the filesystem such that the global state can be found by
|
||||||
|
the xor-sum of these deltas.
|
||||||
|
|
||||||
|
```
|
||||||
|
.--------. .--------. .--------. .--------. .--------.
|
||||||
|
.| |->| gdelta |->| |->| gdelta |->| gdelta |
|
||||||
|
|| | || 0x23 | || | || 0xff | || 0xce |
|
||||||
|
|| | || | || | || | || |
|
||||||
|
|'--------' |'--------' |'--------' |'--------' |'--------'
|
||||||
|
'--------' '----|---' '--------' '----|---' '----|---'
|
||||||
|
v v v
|
||||||
|
0x00 --> xor ------------------> xor ------> xor --> gstate = 0x12
|
||||||
|
```
|
||||||
|
|
||||||
|
Note that storing globals this way is very expensive in terms of storage usage,
|
||||||
|
so any global state should be kept very small.
|
||||||
|
|
||||||
|
The size and format of each piece of global state depends on the type, which
|
||||||
|
is stored in the chunk field. Currently, the only global state is move state,
|
||||||
|
which is outlined below.
|
||||||
|
|
||||||
|
---
|
||||||
|
#### `0x7ff` LFS_TYPE_MOVESTATE
|
||||||
|
|
||||||
|
Provides delta bits for the global move state.
|
||||||
|
|
||||||
|
The move state in littlefs is used to store info about operations that could
|
||||||
|
cause to filesystem to go out of sync if the power is lost. The operations
|
||||||
|
where this could occur is moves of files between metadata pairs and any
|
||||||
|
operation that changes metadata pairs on the threaded linked-list.
|
||||||
|
|
||||||
|
In the case of moves, the move state contains a tag + metadata pair describing
|
||||||
|
the source of the ongoing move. If this tag is non-zero, that means that power
|
||||||
|
was lost during a move, and the file exists in two different locations. If this
|
||||||
|
happens, the source of the move should be considered deleted, and the move

operations to the filesystem.
|
||||||
|
|

|
In the case of operations to the threaded linked-list, a single "sync" bit is
|
||||||
|
used to indicate that a modification is ongoing. If this sync flag is set, the
|
||||||
|
threaded linked-list will need to be checked for errors before it can be used
|
||||||
|
reliably. The exact cases to check for are described above in the tail tag.

|
is in-sync. If set, the threaded linked-list should be checked for errors.
|
||||||
|
|
||||||
|
2. **Move type (11-bits)** - Type of move being performed. Must be either
|
||||||
|
`0x000`, indicating no move, or `0x4ff` indicating the source file should
|
||||||
|
be deleted.
|
||||||
|
|
||||||
|
3. **Move id (10-bits)** - The file id being moved.
|
||||||
|
|
||||||
|
4. **Metadata pair (8-bytes)** - Pointer to the metadata-pair containing
|
||||||
|
the move.

#### `0x5xx` LFS_TYPE_CRC
|
||||||
|
|
||||||
|
Last but not least, the CRC tag marks the end of a commit and provides a
|
||||||
|
checksum for any commits to the metadata block.
|
||||||
|
|
||||||
|
The first 32-bits of the data contain a CRC-32 with a polynomial of
|
||||||
|
`0x04c11db7` initialized with `0xffffffff`. This CRC provides a checksum for
|
||||||
|
all metadata since the previous CRC tag, including the CRC tag itself. For
|
||||||
|
the first commit, this includes the revision count for the metadata block.
|
||||||
|
|
||||||
|
However, the size of the data is not limited to 32-bits. The data field may
|
||||||
|
larger to pad the commit to the next program-aligned boundary.
|
||||||
|
|
||||||
|
In addition, the CRC tag's chunk field contains a set of flags which can
|
||||||
|
change the behaviour of commits. Currently the only flag in use is the lowest
|
||||||
|
bit, which determines the expected state of the valid bit for any following
|
||||||
|
tags. This is used to guarantee that unwritten storage in a metadata block
|
||||||
|
will be detected as invalid.

||||||

CRC fields:

|

any tags in the next commit.
|
||||||
|
|
||||||
|
2. **CRC (32-bits)** - CRC-32 with a polynomial of `0x04c11db7` initialized
|
||||||
|
with `0xffffffff`.
|
||||||
|
|
||||||
|
3. **Padding** - Padding to the next program-aligned boundary. No guarantees
|
||||||
|
are made about the contents.

#### `0x5ff` LFS_TYPE_FCRC
|
||||||
|
|
||||||
|
Added in lfs2.1, the optional FCRC tag contains a checksum of some amount of
|
||||||
|
bytes in the next commit at the time it was erased. This allows us to ensure
|
||||||
|
that we only ever program erased bytes, even if a previous commit failed due
|
||||||
|
to power-loss.
|
||||||
|
|
||||||
|
When programming a commit, the FCRC size must be at least as large as the
|
||||||
|
program block size. However, the program block is not saved on disk, and can
|
||||||
|
change between mounts, so the FCRC size on disk may be different than the
|
||||||
|
current program block size.
|
||||||
|
|
||||||
|
If the FCRC is missing or the checksum does not match, we must assume a
|
||||||
|
commit was attempted but failed due to power-loss.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
FCRC fields:
|
||||||
|
|
||||||
|
1. **FCRC size (32-bits)** - Number of bytes after this commit's CRC tag's
|
||||||
|
padding to include in the FCRC.
|
||||||
|
|
||||||
|
2. **FCRC (32-bits)** - CRC of the bytes after this commit's CRC tag's padding
|
||||||
|
when erased. Like the CRC tag, this uses a CRC-32 with a polynomial of
|
||||||
|
`0x04c11db7` initialized with `0xffffffff`.
