squashfs: add the mount parameter theads=<single|multi|percpu>
Patch series 'squashfs: Add the mount parameter "threads="'.
Currently, Squashfs supports multiple decompressor parallel modes. However, this mode can be configured only during kernel building and does not support flexible selection during runtime.
In the current patch set, the mount parameter "threads=" is added to allow users to select the parallel decompressor mode and configure the number of decompressors when mounting a file system.
"threads=<single|multi|percpu|1|2|3|...>" The upper limit is num_online_cpus() * 2.
This patch (of 2):
Squashfs supports three decompression concurrency modes: Single-thread mode: concurrent reads are blocked and the memory overhead is small. Multi-thread mode/percpu mode: reduces concurrent read blocking but increases memory overhead.
The corresponding schema must be fixed at compile time. During mounting, the concurrent decompression mode cannot be adjusted based on file read blocking.
The mount parameter theads=<single|multi|percpu> is added to select the concurrent decompression mode of a single SquashFS file system image.

squashfs: migrate from ll_rw_block usage to BIO
ll_rw_block() function has been deprecated in favor of BIO which appears to come with large performance improvements.
This patch decreases boot time by close to 40% when using squashfs for the root file-system. This is observed at least in the context of starting an Android VM on Chrome OS using crosvm. The patch was tested on 4.19 as well as master.
This patch is largely based on Adrien Schildknecht's patch that was originally sent as https://lkml.org/lkml/2017/9/22/814 though with some significant changes and simplifications while also taking Phillip Lougher's feedback into account, around preserving support for FILE_CACHE in particular.

Squashfs: Compute expected length from inode size rather than block length
Previously in squashfs_readpage() when copying data into the page cache, it used the length of the datablock read from the filesystem (after decompression). However, if the filesystem has been corrupted this data block may be short, which will leave pages unfilled.
The fix for this is to compute the expected number of bytes to copy from the inode size, and use this to detect if the block is short.

squashfs metadata 2: electric boogaloo
Anatoly continues to find issues with fuzzed squashfs images.
This time, corrupt, missing, or undersized data for the page filling wasn't checked for, because the squashfs_{copy,read}_cache() functions did the squashfs_copy_data() call without checking the resulting data size.
Which could result in the page cache pages being incompletely filled in, and no error indication to the user space reading garbage data.
So make a helper function for the "fill in pages" case, because the exact same incomplete sequence existed in two places.
[ I should have made a squashfs branch for these things, but I didn't intend to start doing them in the first place.
My historical connection through cramfs is why I got into looking at these issues at all, and every time I (continue to) think it's a one-off.
Because _this_ time is always the last time. Right? - Linus ]

Squashfs: Restructure squashfs_readpage()
Restructure squashfs_readpage() splitting it into separate functions for datablocks, fragments and sparse blocks.
Move the memcpying (from squashfs cache entry) implementation of squashfs_readpage_block into file_cache.c
This allows different implementations to be supported.

Squashfs: Generalise paging handling in the decompressors
Further generalise the decompressors by adding a page handler abstraction. This adds helpers to allow the decompressors to access and process the output buffers in an implementation independant manner.
This allows different types of output buffer to be passed to the decompressors, with the implementation specific aspects handled at decompression time, but without the knowledge being held in the decompressor wrapper code.
This will allow the decompressors to handle Squashfs cache buffers, and page cache pages.
This patch adds the abstraction and an implementation for the caches.

Squashfs: Refactor decompressor interface and code
The decompressor interface and code was written from the point of view of single-threaded operation. In doing so it mixed a lot of single-threaded implementation specific aspects into the decompressor code and elsewhere which makes it difficult to seamlessly support multiple different decompressor implementations.
This patch does the following:
1. It removes compressor_options parsing from the decompressor init() function. This allows the decompressor init() function to be dynamically called to instantiate multiple decompressors, without the compressor options needing to be read and parsed each time.
2. It moves threading and all sleeping operations out of the decompressors. In doing so, it makes the decompressors non-blocking wrappers which only deal with interfacing with the decompressor implementation.
3. It splits decompressor.[ch] into decompressor generic functions in decompressor.[ch], and moves the single threaded decompressor implementation into decompressor_single.c.
The result of this patch is Squashfs should now be able to support multiple decompressors by adding new decompressor_xxx.c files with specialised implementations of the functions in decompressor_single.c

Squashfs: extend decompressor framework to handle compression options
Extend decompressor framework to handle compression options stored in the filesystem. These options can be used by the relevant decompressor at initialisation time to over-ride defaults.
The presence of compression options in the filesystem is indicated by the COMP_OPT filesystem flag. If present the data is read from the filesystem and passed to the decompressor init function. The decompressor init function signature has been extended to take this data.
Also update the init function signature in the glib, lzo and xz decompressor wrappers.
