Firstly, EROFS LZMA algorithm support, specifically called MicroLZMA, is available as an option for embedded devices, LiveCDs and/or as the secondary auxiliary compression algorithm besides the primary algorithm in one file. In order to better support the LZMA fixed-sized output compression, especially for 4KiB pcluster size (which has lowest memory pressure thus useful for memory-sensitive scenarios), Lasse introduced a new LZMA header/container format called MicroLZMA to minimize the original LZMA1 header (for example, we don't need to waste 4-byte dictionary size and another 8-byte uncompressed size, which can be calculated by fs directly, for each pcluster) and enable EROFS fixed-sized output compression. Note that MicroLZMA can also be later used by other things in addition to EROFS too where wasting minimal amount of space for headers is important and it can be only compiled by enabling XZ_DEC_MICROLZMA. MicroLZMA has been supported by the latest upstream XZ embedded [1] & XZ utils [2], apply the latest related XZ embedded upstream patches by the XZ author Lasse here. Secondly, multiple device is also supported in this cycle, which is designed for multi-layer container images. By working together with inter-layer data deduplication and compression, we can achieve the next high-performance container image solution. Our team will announce the new Nydus container image service [3] implementation with new RAFS v6 (EROFS-compatible) format in Open Source Summit 2021 China [4] soon. Besides, the secondary compression head support and readmore decompression strategy are also included in this cycle. There are also some minor bugfixes and cleanups, as always. Summary: - support multiple devices for multi-layer container images; - support the secondary compression head; - support readmore decompression strategy; - support new LZMA algorithm (specifically called MicroLZMA); - some bugfixes & cleanups" * tag 'erofs-for-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: erofs: don't trigger WARN() when decompression fails erofs: get rid of ->lru usage erofs: lzma compression support erofs: rename some generic methods in decompressor lib/xz, lib/decompress_unxz.c: Fix spelling in comments lib/xz: Add MicroLZMA decoder lib/xz: Move s->lzma.len = 0 initialization to lzma_reset() lib/xz: Validate the value before assigning it to an enum variable lib/xz: Avoid overlapping memcpy() with invalid input with in-place decompression erofs: introduce readmore decompression strategy erofs: introduce the secondary compression head erofs: get compression algorithms directly on mapping erofs: add multiple device support erofs: decouple basic mount options from fs_context erofs: remove the fast path of per-CPU buffer decompression |
