Wed, 25 May 2022 03:42:04 +0200

Merge tag 'erofs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofsPull erofs (and fscache) updates from Gao Xiang: "After working on it on the mailing list for more than half a year, we finally form 'erofs over fscache' feature into shape. Hopefully it could bring more possibility to the communities. The story mainly started from a new project what we called "RAFS v6" [1] for Nydus image service almost a year ago, which enhances EROFS to be a new form of one bootstrap (which includes metadata representing the whole fs tree) + several data-deduplicated content addressable blobs (actually treated as multiple devices). Each blob can represent one container image layer but not quite exactly since all new data can be fully existed in the previous blobs so no need to introduce another new blob. It is actually not a new idea (at least on my side it's much like a simpilied casync [2] for now) and has many benefits over per-file blobs or some other exist ways since typically each RAFS v6 image only has dozens of device blobs instead of thousands of per-file blobs. It's easy to be signed with user keys as a golden image, transfered untouchedly with minimal overhead over the network, kept in some type of storage conveniently, and run with (optional) runtime verification but without involving too many irrelevant features crossing the system beyond EROFS itself. At least it's our final goal and we're keeping working on it. There was also a good summary of this approach from the casync author [3]. Regardless further optimizations, this work is almost done in the previous Linux release cycles. In this round, we'd like to introduce on-demand load for EROFS with the fscache/cachefiles infrastructure, considering the following advantages: - Introduce new file-based backend to EROFS. Although each image only contains dozens of blobs but in densely-deployed runC host for example, there could still be massive blobs on a machine, which is messy if each blob is treated as a device. In contrast, fscache and cachefiles are really great interfaces for us to make them work. - Introduce on-demand load to fscache and EROFS. Previously, fscache is mainly used to caching network-likewise filesystems, now it can support on-demand downloading for local fses too with the exact localfs on-disk format. It has many advantages which we're been described in the latest patchset cover letter [4]. In addition to that, most importantly, the cached data is still stored in the original local fs on-disk format so that it's still the one signed with private keys but only could be partially available. Users can fully trust it during running. Later, users can also back up cachefiles easily to another machine. - More reliable on-demand approach in principle. After data is all available locally, user daemon can be no longer online in some use cases, which helps daemon crash recovery (filesystems can still in service) and hot-upgrade (user daemon can be upgraded more frequently due to new features or protocols introduced.) - Other format can also be converted to EROFS filesystem format over the internet on the fly with the new on-demand load feature and mounted. That is entirely possible with on-demand load feature as long as such archive format metadata can be fetched in advance like stargz. In addition, although currently our target user is Nydus image service [5], but laterly, it can be used for other use cases like on-demand system booting, etc. As for the fscache on-demand load feature itself, strictly it can be used for other local fses too. Laterly we could promote most code to the iomap infrastructure and also enhance it in the read-write way if other local fses are interested. Thanks David Howells for taking so much time and patience on this these months, many thanks with great respect here again! Thanks Jeffle for working on this feature and Xin Yin from Bytedance for asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and Yan Song for testing, much appeciated. We're also exploring more possibly over fscache cache management over FSDAX for secure containers and working on more improvements and useful features for fscache, cachefiles, and on-demand load. In addition to "erofs over fscache", NFS export and idmapped mount are also completed in this cycle for container use cases as well. Summary: - Add erofs on-demand load support over fscache - Support NFS export for erofs - Support idmapped mounts for erofs - Don't prompt for risk any more when using big pcluster - Fix buffer copy overflow of ztailpacking feature - Several minor cleanups"[1] https://lore.kernel.org/r/20210730194625.93856-1-hsiangkao@linux.alibaba.com[2] https://github.com/systemd/casync[3] http://0pointer.net/blog/casync-a-tool-for-distributing-file-system-images.html[4] https://lore.kernel.org/r/20220509074028.74954-1-jefflexu@linux.alibaba.com[5] https://github.com/dragonflyoss/image-service* tag 'erofs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs: (29 commits) erofs: scan devices from device table erofs: change to use asynchronous io for fscache readpage/readahead erofs: add 'fsid' mount option erofs: implement fscache-based data readahead erofs: implement fscache-based data read for inline layout erofs: implement fscache-based data read for non-inline layout erofs: implement fscache-based metadata read erofs: register fscache context for extra data blobs erofs: register fscache context for primary data blob erofs: add erofs_fscache_read_folios() helper erofs: add anonymous inode caching metadata for data blobs erofs: add fscache context helper functions erofs: register fscache volume erofs: add fscache mode check helper erofs: make erofs_map_blocks() generally available cachefiles: document on-demand read mode cachefiles: add tracepoints for on-demand read mode cachefiles: enable on-demand read mode cachefiles: implement on-demand read cachefiles: notify the user daemon when withdrawing cookie ...

Mon, 25 Apr 2022 14:21:24 +0200

cachefiles: notify the user daemon when looking up cookieFscache/CacheFiles used to serve as a local cache for a remotenetworking fs. A new on-demand read mode will be introduced forCacheFiles, which can boost the scenario where on-demand read semanticsare needed, e.g. container image distribution.The essential difference between these two modes is seen when a cachemiss occurs: In the original mode, the netfs will fetch the data fromthe remote server and then write it to the cache file; in on-demandread mode, fetching the data and writing it into the cache is delegatedto a user daemon.As the first step, notify the user daemon when looking up cookie. Inthis case, an anonymous fd is sent to the user daemon, through which theuser daemon can write the fetched data to the cache file. Since the userdaemon may move the anonymous fd around, e.g. through dup(), an objectID uniquely identifying the cache file is also attached.Also add one advisory flag (FSCACHE_ADV_WANT_CACHE_SIZE) suggesting thatthe cache file size shall be retrieved at runtime. This helps thescenario where one cache file contains multiple netfs files, e.g. forthe purpose of deduplication. In this case, netfs itself has no idea thesize of the cache file, whilst the user daemon should give the hint onit.Signed-off-by: Jeffle Xu Link: https://lore.kernel.org/r/20220509074028.74954-3-jefflexu@linux.alibaba.comAcked-by: David Howells Signed-off-by: Gao Xiang List of files: /linux/fs/cachefiles/Makefile
