Linus Torvalds	65965d9530	Merge tag 'erofs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs ... Pull 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.

Linus Torvalds	f30fabe78a	Merge tag 'fs.idmapped.v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux ... Pull fs idmapping updates from Christian Brauner: "This contains two minor updates: - An update to the idmapping documentation by Rodrigo making it easier to understand that we first introduce several use-cases that fail without idmapped mounts simply to explain how they can be handled with idmapped mounts. - When changing a mount's idmapping we now hold writers to make it more robust. This is similar to turning a mount ro with the difference that in contrast to turning a mount ro changing the idmapping can only ever be done once while a mount can transition between ro and rw as much as it wants. The vfs layer itself takes care to retrieve the idmapping of a mount once ensuring that the idmapping used for vfs permission checking is identical to the idmapping passed down to the filesystem. All filesystems with FS_ALLOW_IDMAP raised take the same precautions as the vfs in code-paths that are outside of direct control of the vfs such as ioctl()s. However, holding writers makes this more robust and predictable for both the kernel and userspace. This is a minor user-visible change. But it is extremely unlikely to matter. The caller must've created a detached mount via OPEN_TREE_CLONE and then handed that O_PATH fd to another process or thread which then must've gotten a writable fd for that mount and started creating files in there while the caller is still changing mount properties. While not impossible it will be an extremely rare corner-case and should in general be considered a bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC or MOUNT_ATTR_NODEV while allowing someone else to perform lookups or exec'ing in parallel by handing them a copy of the OPEN_TREE_CLONE fd or another fd beneath that mount. I've pinged all major users of idmapped mounts pointing out this change and none of them have active writers on a mount while still changing mount properties. It would've been strange if they did. The rest and majority of the work will be coming through the overlayfs tree this cycle. In addition to overlayfs this cycle should also see support for idmapped mounts on erofs as I've acked a patch to this effect a little while ago" * tag 'fs.idmapped.v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: hold writers when changing mount's idmapping docs: Add small intro to idmap examples	2022-05-24 18:19:06 -07:00

Bjorn Andersson	e98a860f65	leds: qcom-lpg: Require pattern to follow documentation ... The leds-trigger-pattern documentation describes how the brightness of the LED should transition linearly from one brightness value to the next, over the given delta_t. But the pattern engine in the Qualcomm LPG hardware only supports holding the brightness for each entry for the period. This subset of patterns can be represented in the leds-trigger-pattern by injecting zero-time transitions after each entry in the pattern, resulting in a pattern that pattern that can be rendered by the LPG. Rework LPG pattern interface to require these zero-time transitions, to make it comply with this subset of patterns and reject the patterns it can't render.

Linus Torvalds	ac2ab99072	Merge tag 'random-5.19-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random ... Pull random number generator updates from Jason Donenfeld: "These updates continue to refine the work began in 5.17 and 5.18 of modernizing the RNG's crypto and streamlining and documenting its code. New for 5.19, the updates aim to improve entropy collection methods and make some initial decisions regarding the "premature next" problem and our threat model. The cloc utility now reports that random.c is 931 lines of code and 466 lines of comments, not that basic metrics like that mean all that much, but at the very least it tells you that this is very much a manageable driver now. Here's a summary of the various updates: - The random_get_entropy() function now always returns something at least minimally useful. This is the primary entropy source in most collectors, which in the best case expands to something like RDTSC, but prior to this change, in the worst case it would just return 0, contributing nothing. For 5.19, additional architectures are wired up, and architectures that are entirely missing a cycle counter now have a generic fallback path, which uses the highest resolution clock available from the timekeeping subsystem. Some of those clocks can actually be quite good, despite the CPU not having a cycle counter of its own, and going off-core for a stamp is generally thought to increase jitter, something positive from the perspective of entropy gathering. Done very early on in the development cycle, this has been sitting in next getting some testing for a while now and has relevant acks from the archs, so it should be pretty well tested and fine, but is nonetheless the thing I'll be keeping my eye on most closely. - Of particular note with the random_get_entropy() improvements is MIPS, which, on CPUs that lack the c0 count register, will now combine the high-speed but short-cycle c0 random register with the lower-speed but long-cycle generic fallback path. - With random_get_entropy() now always returning something useful, the interrupt handler now collects entropy in a consistent construction. - Rather than comparing two samples of random_get_entropy() for the jitter dance, the algorithm now tests many samples, and uses the amount of differing ones to determine whether or not jitter entropy is usable and how laborious it must be. The problem with comparing only two samples was that if the cycle counter was extremely slow, but just so happened to be on the cusp of a change, the slowness wouldn't be detected. Taking many samples fixes that to some degree. This, combined with the other improvements to random_get_entropy(), should make future unification of /dev/random and /dev/urandom maybe more possible. At the very least, were we to attempt it again today (we're not), it wouldn't break any of Guenter's test rigs that broke when we tried it with 5.18. So, not today, but perhaps down the road, that's something we can revisit. - We attempt to reseed the RNG immediately upon waking up from system suspend or hibernation, making use of the various timestamps about suspend time and such available, as well as the usual inputs such as RDRAND when available. - Batched randomness now falls back to ordinary randomness before the RNG is initialized. This provides more consistent guarantees to the types of random numbers being returned by the various accessors. - The "pre-init injection" code is now gone for good. I suspect you in particular will be happy to read that, as I recall you expressing your distaste for it a few months ago. Instead, to avoid a "premature first" issue, while still allowing for maximal amount of entropy availability during system boot, the first 128 bits of estimated entropy are used immediately as it arrives, with the next 128 bits being buffered. And, as before, after the RNG has been fully initialized, it winds up reseeding anyway a few seconds later in most cases. This resulted in a pretty big simplification of the initialization code and let us remove various ad-hoc mechanisms like the ugly crng_pre_init_inject(). - The RNG no longer pretends to handle the "premature next" security model, something that various academics and other RNG designs have tried to care about in the past. After an interesting mailing list thread, these issues are thought to be a) mainly academic and not practical at all, and b) actively harming the real security of the RNG by delaying new entropy additions after a potential compromise, making a potentially bad situation even worse. As well, in the first place, our RNG never even properly handled the premature next issue, so removing an incomplete solution to a fake problem was particularly nice. This allowed for numerous other simplifications in the code, which is a lot cleaner as a consequence. If you didn't see it before, https://lore.kernel.org/lkml/YmlMGx6+uigkGiZ0@zx2c4.com/ may be a thread worth skimming through. - While the interrupt handler received a separate code path years ago that avoids locks by using per-cpu data structures and a faster mixing algorithm, in order to reduce interrupt latency, input and disk events that are triggered in hardirq handlers were still hitting locks and more expensive algorithms. Those are now redirected to use the faster per-cpu data structures. - Rather than having the fake-crypto almost-siphash-based random32 implementation be used right and left, and in many places where cryptographically secure randomness is desirable, the batched entropy code is now fast enough to replace that. - As usual, numerous code quality and documentation cleanups. For example, the initialization state machine now uses enum symbolic constants instead of just hard coding numbers everywhere. - Since the RNG initializes once, and then is always initialized thereafter, a pretty heavy amount of code used during that initialization is never used again. It is now completely cordoned off using static branches and it winds up in the .text.unlikely section so that it doesn't reduce cache compactness after the RNG is ready. - A variety of functions meant for waiting on the RNG to be initialized were only used by vsprintf, and in not a particularly optimal way. Replacing that usage with a more ordinary setup made it possible to remove those functions. - A cleanup of how we warn userspace about the use of uninitialized /dev/urandom and uninitialized get_random_bytes() usage. Interestingly, with the change you merged for 5.18 that attempts to use jitter (but does not block if it can't), the majority of users should never see those warnings for /dev/urandom at all now, and the one for in-kernel usage is mainly a debug thing. - The file_operations struct for /dev/[u]random now implements .read_iter and .write_iter instead of .read and .write, allowing it to also implement .splice_read and .splice_write, which makes splice(2) work again after it was broken here (and in many other places in the tree) during the set_fs() removal. This was a bit of a last minute arrival from Jens that hasn't had as much time to bake, so I'll be keeping my eye on this as well, but it seems fairly ordinary. Unfortunately, read_iter() is around 3% slower than read() in my tests, which I'm not thrilled about. But Jens and Al, spurred by this observation, seem to be making progress in removing the bottlenecks on the iter paths in the VFS layer in general, which should remove the performance gap for all drivers. - Assorted other bug fixes, cleanups, and optimizations. - A small SipHash cleanup" * tag 'random-5.19-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: (49 commits) random: check for signals after page of pool writes random: wire up fops->splice_{read,write}_iter() random: convert to using fops->write_iter() random: convert to using fops->read_iter() random: unify batched entropy implementations random: move randomize_page() into mm where it belongs random: remove mostly unused async readiness notifier random: remove get_random_bytes_arch() and add rng_has_arch_random() random: move initialization functions out of hot pages random: make consistent use of buf and len random: use proper return types on get_random_{int,long}_wait() random: remove extern from functions in header random: use static branch for crng_ready() random: credit architectural init the exact amount random: handle latent entropy and command line from random_init() random: use proper jiffies comparison macro random: remove ratelimiting for in-kernel unseeded randomness random: move initialization out of reseeding hot path random: avoid initializing twice in credit race random: use symbolic constants for crng_init states ...	2022-05-24 11:58:10 -07:00

Design-wise, it differs from AMD's solution considerably: it uses a software module which runs in a special CPU mode called (Secure Arbitration Mode) SEAM.
