TTY/Serial driver fixes for 5.4-rc3
Here are some small tty and serial driver fixes for 5.4-rc3 that resolve a number of reported issues and regressions. None of these are huge, full details are in the shortlog. THere's also a MAINTAINERS update that I think you might have already taken in your tree already, but git should handle that merge easily. All have been in linux-next with no reported issues.

It is a generic interface designed to copy a struct from userspace. The helper will be especially useful for structs versioned by size of which we have quite a few. This allows for backwards compatibility, i.e. an extended struct can be passed to an older kernel, or a legacy struct can be passed to a newer kernel. For the first case (extended struct, older kernel) the new fields in an extended struct can be set to zero and the struct safely passed to an older kernel. The most obvious benefit is that this helper lets us get rid of duplicate code present in at least sched_setattr(), perf_event_open(), and clone3(). More importantly it will also help to ensure that users implementing versioning-by-size end up with the same core semantics. This point is especially crucial since we have at least one case where versioning-by-size is used but with slighly different semantics: sched_setattr(), perf_event_open(), and clone3() all do do similar checks to copy_struct_from_user() while rt_sigprocmask(2) always rejects differently-sized struct arguments. With this pull request we also switch over sched_setattr(), perf_event_open(), and clone3() to use the new helper" * tag 'copy-struct-from-user-v5.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: usercopy: Add parentheses around assignment in test_copy_struct_from_user perf_event_open: switch to copy_struct_from_user() sched_setattr: switch to copy_struct_from_user() clone3: switch to copy_struct_from_user() lib: introduce copy_struct_from_user() helper |

clone3: switch to copy_struct_from_user()
Switch clone3() syscall from it's own copying struct clone_args from userspace to the new dedicated copy_struct_from_user() helper. The change is very straightforward, and helps unify the syscall interface for struct-from-userspace syscalls. Additionally, explicitly define CLONE_ARGS_SIZE_VER0 to match the other users of the struct-extension pattern.

Highlights:
- add a new knfsd file cache, so that we don't have to open and close on each (NFSv2/v3) READ or WRITE. This can speed up read and write in some cases. It also replaces our readahead cache. - Prevent silent data loss on write errors, by treating write errors like server reboots for the purposes of write caching, thus forcing clients to resend their writes. - Tweak the code that allocates sessions to be more forgiving, so that NFSv4.1 mounts are less likely to hang when a server already has a lot of clients. - Eliminate an arbitrary limit on NFSv4 ACL sizes; they should now be limited only by the backend filesystem and the maximum RPC size. - Allow the server to enforce use of the correct kerberos credentials when a client reclaims state after a reboot.

mm: introduce MADV_PAGEOUT
When a process expects no accesses to a certain memory range for a long time, it could hint kernel that the pages can be reclaimed instantly but data should be preserved for future use. This could reduce workingset eviction so it ends up increasing performance. This patch introduces the new MADV_PAGEOUT hint to madvise(2) syscall. MADV_PAGEOUT can be used by a process to mark a memory range as not expected to be used for a long time so that kernel reclaims *any LRU* pages instantly. The hint can help kernel in deciding which pages to evict proactively. A note: It doesn't apply SWAP_CLUSTER_MAX LRU page isolation limit intentionally because it's automatically bounded by PMD size. If PMD size(e.g., 256) makes some trouble, we could fix it later by limit it to SWAP_CLUSTER_MAX[1]. - man-page material MADV_PAGEOUT (since Linux x.x) Do not expect access in the near future so pages in the specified regions could be reclaimed instantly regardless of memory pressure. Thus, access in the range after successful operation could cause major page fault but never lose the up-to-date contents unlike MADV_DONTNEED. Pages belonging to a shared mapping are only processed if a write access is allowed for the calling process. MADV_PAGEOUT cannot be applied to locked pages, Huge TLB pages, or VM_PFNMAP pages.

mm: introduce MADV_COLD
Patch series "Introduce MADV_COLD and MADV_PAGEOUT", v7. - Background The Android terminology used for forking a new process and starting an app from scratch is a cold start, while resuming an existing app is a hot start. While we continually try to improve the performance of cold starts, hot starts will always be significantly less power hungry as well as faster so we are trying to make hot start more likely than cold start. To increase hot start, Android userspace manages the order that apps should be killed in a process called ActivityManagerService. ActivityManagerService tracks every Android app or service that the user could be interacting with at any time and translates that into a ranked list for lmkd(low memory killer daemon). They are likely to be killed by lmkd if the system has to reclaim memory. In that sense they are similar to entries in any other cache. Those apps are kept alive for opportunistic performance improvements but those performance improvements will vary based on the memory requirements of individual workloads. - Problem Naturally, cached apps were dominant consumers of memory on the system. However, they were not significant consumers of swap even though they are good candidate for swap. Under investigation, swapping out only begins once the low zone watermark is hit and kswapd wakes up, but the overall allocation rate in the system might trip lmkd thresholds and cause a cached process to be killed(we measured performance swapping out vs. zapping the memory by killing a process. Unsurprisingly, zapping is 10x times faster even though we use zram which is much faster than real storage) so kill from lmkd will often satisfy the high zone watermark, resulting in very few pages actually being moved to swap. - Approach The approach we chose was to use a new interface to allow userspace to proactively reclaim entire processes by leveraging platform information. This allowed us to bypass the inaccuracy of the kernel’s LRUs for pages that are known to be cold from userspace and to avoid races with lmkd by reclaiming apps as soon as they entered the cached state. Additionally, it could provide many chances for platform to use much information to optimize memory efficiency. To achieve the goal, the patchset introduce two new options for madvise. One is MADV_COLD which will deactivate activated pages and the other is MADV_PAGEOUT which will reclaim private pages instantly. These new options complement MADV_DONTNEED and MADV_FREE by adding non-destructive ways to gain some free memory space. MADV_PAGEOUT is similar to MADV_DONTNEED in a way that it hints the kernel that memory region is not currently needed and should be reclaimed immediately; MADV_COLD is similar to MADV_FREE in a way that it hints the kernel that memory region is not currently needed and should be reclaimed when memory pressure rises. This patch (of 5): When a process expects no accesses to a certain memory range, it could give a hint to kernel that the pages can be reclaimed when memory pressure happens but data should be preserved for future use. This could reduce workingset eviction so it ends up increasing performance. This patch introduces the new MADV_COLD hint to madvise(2) syscall. MADV_COLD can be used by a process to mark a memory range as not expected to be used in the near future. The hint can help kernel in deciding which pages to evict early during memory pressure. It works for every LRU pages like MADV_[DONTNEED|FREE]. IOW, It moves active file page -> inactive file LRU active anon page -> inacdtive anon LRU Unlike MADV_FREE, it doesn't move active anonymous pages to inactive file LRU's head because MADV_COLD is a little bit different symantic. MADV_FREE means it's okay to discard when the memory pressure because the content of the page is *garbage* so freeing such pages is almost zero overhead since we don't need to swap out and access afterward causes just minor fault. Thus, it would make sense to put those freeable pages in inactive file LRU to compete other used-once pages. It makes sense for implmentaion point of view, too because it's not swapbacked memory any longer until it would be re-dirtied. Even, it could give a bonus to make them be reclaimed on swapless system. However, MADV_COLD doesn't mean garbage so reclaiming them requires swap-out/in in the end so it's bigger cost. Since we have designed VM LRU aging based on cost-model, anonymous cold pages would be better to position inactive anon's LRU list, not file LRU. Furthermore, it would help to avoid unnecessary scanning if system doesn't have a swap device. Let's start simpler way without adding complexity at this moment. However, keep in mind, too that it's a caveat that workloads with a lot of pages cache are likely to ignore MADV_COLD on anonymous memory because we rarely age anonymous LRU lists. * man-page material MADV_COLD (since Linux x.x) Pages in the specified regions will be treated as less-recently-accessed compared to pages in the system with similar access frequencies. In contrast to MADV_FREE, the contents of the region are preserved regardless of subsequent writes to pages. MADV_COLD cannot be applied to locked pages, Huge TLB pages, or VM_PFNMAP pages.

nvme: allow 64-bit results in passthru commands
It is not possible to get 64-bit results from the passthru commands, what prevents from getting for the Capabilities (CAP) property value. As a result, it is not possible to implement IOL's NVMe Conformance test 4.3 Case 1 for Fabrics targets [1] (page 123). This issue has been already discussed [2], but without a solution. This patch solves the problem by adding new ioctls with a new passthru structure, including 64-bit results. The older ioctls stay unchanged.

Add new KVM capability KVM_CAP_ HYPERV_DIRECT_TLBFLUSH for user space to enable Hyper-V direct tlb function and this function is default to be disabled in KVM.

fs-verity for 5.4
Please consider pulling fs-verity for 5.4. fs-verity is a filesystem feature that provides Merkle tree based hashing (similar to dm-verity) for individual readonly files, mainly for the purpose of efficient authenticity verification. This pull request includes: (a) The fs/verity/ support layer and documentation. (b) fs-verity support for ext4 and f2fs. Compared to the original fs-verity patchset from last year, the UAPI to enable fs-verity on a file has been greatly simplified. Lots of other things were cleaned up too. fs-verity is planned to be used by two different projects on Android; most of the userspace code is in place already. Another userspace tool ("fsverity-utils"), and xfstests, are also available. e2fsprogs and f2fs-tools already have fs-verity support. Other people have shown interest in using fs-verity too. I've tested this on ext4 and f2fs with xfstests, both the existing tests and the new fs-verity tests. This has also been in linux-next since July 30 with no reported issues except a couple minor ones I found myself and folded in fixes for. Ted and I will be co-maintaining fs-verity. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCXX8ZUBQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOK2YOAQCbnBAKWDxXS3alLARRwjQLjmEtQIGl gsek+WurFIg/zAEAlpSzHwu13LvYzTqv3rhO2yhSlvhnDu4GQEJPXPm0wgM= =ID0n -----END PGP SIGNATURE----- Merge tag 'fsverity-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fs-verity support from Eric Biggers: "fs-verity is a filesystem feature that provides Merkle tree based hashing (similar to dm-verity) for individual readonly files, mainly for the purpose of efficient authenticity verification.

fscrypt update for 5.4
This is a large update to fs/crypto/ which includes: - Add ioctls that add/remove encryption keys to/from a filesystem-level keyring. These fix user-reported issues where e.g. an encrypted home directory can break NetworkManager, sshd, Docker, etc. because they don't get access to the needed keyring. These ioctls also provide a way to lock encrypted directories that doesn't use the vm.drop_caches sysctl, so is faster, more reliable, and doesn't always need root. - Add a new encryption policy version ("v2") which switches to a more standard, secure, and flexible key derivation function, and starts verifying that the correct key was supplied before using it. The key derivation improvement is needed for its own sake as well as for ongoing feature work for which the current way is too inflexible. Work is in progress to update both Android and the 'fscrypt' userspace tool to use both these features. (Working patches are available and just need to be reviewed+merged.) Chrome OS will likely use them too. This has also been tested on ext4, f2fs, and ubifs with xfstests -- both the existing encryption tests, and the new tests for this. This has also been in linux-next since Aug 16 with no reported issues.

virtio-fs: add virtiofs filesystem
Add a basic file system module for virtio-fs. This does not yet contain shared data support between host and guest or metadata coherency speedups. However it is already significantly faster than virtio-9p. Design Overview =============== With the goal of designing something with better performance and local file system semantics, a bunch of ideas were proposed. - Use fuse protocol (instead of 9p) for communication between guest and host. Guest kernel will be fuse client and a fuse server will run on host to serve the requests. - For data access inside guest, mmap portion of file in QEMU address space and guest accesses this memory using dax. That way guest page cache is bypassed and there is only one copy of data (on host). This will also enable mmap(MAP_SHARED) between guests. - For metadata coherency, there is a shared memory region which contains version number associated with metadata and any guest changing metadata updates version number and other guests refresh metadata on next access. This is yet to be implemented. How virtio-fs differs from existing approaches ============================================== The unique idea behind virtio-fs is to take advantage of the co-location of the virtual machine and hypervisor to avoid communication (vmexits). DAX allows file contents to be accessed without communication with the hypervisor. The shared memory region for metadata avoids communication in the common case where metadata is unchanged. By replacing expensive communication with cheaper shared memory accesses, we expect to achieve better performance than approaches based on network file system protocols. In addition, this also makes it easier to achieve local file system semantics (coherency). These techniques are not applicable to network file system protocols since the communications channel is bypassed by taking advantage of shared memory on a local machine. This is why we decided to build virtio-fs rather than focus on 9P or NFS. Caching Modes ============= Like virtio-9p, different caching modes are supported which determine the coherency level as well. The “cache=FOO” and “writeback” options control the level of coherence between the guest and host filesystems. - cache=none metadata, data and pathname lookup are not cached in guest. They are always fetched from host and any changes are immediately pushed to host. - cache=always metadata, data and pathname lookup are cached in guest and never expire. - cache=auto metadata and pathname lookup cache expires after a configured amount of time (default is 1 second). Data is cached while the file is open (close to open consistency). - writeback/no_writeback These options control the writeback strategy. If writeback is disabled, then normal writes will immediately be synchronized with the host fs. If writeback is enabled, then writes may be cached in the guest until the file is closed or an fsync(2) performed. This option has no effect on mmap-ed writes or writes going through the DAX mechanism.

Here is the big char/misc driver pull request for 5.4-rc1. As has been happening in previous releases, more and more individual driver subsystem trees are ending up in here. Now if that is good or bad I can't tell, but hopefully it makes your life easier as it's more of an aggregation of trees together to one merge point for you. Anyway, lots of stuff in here: - habanalabs driver updates - thunderbolt driver updates - misc driver updates - coresight and intel_th hwtracing driver updates - fpga driver updates - extcon driver updates - some dma driver updates - char driver updates - android binder driver updates - nvmem driver updates - phy driver updates - parport driver fixes - pcmcia driver fix - uio driver updates - w1 driver updates - configfs fixes - other assorted driver updates All of these have been in linux-next for a long time with no reported issues.

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1. Lots of churn here, with a few driver/filesystems moving out of staging finally: - erofs moved out of staging - greybus core code moved out of staging Along with that, a new filesytem has been added: - extfat to provide support for those devices requiring that filesystem (i.e. transfer devices to/from windows systems or printers.) Other than that, there a number of new IIO drivers, and lots and lots and lots of staging driver cleanups and minor fixes as people continue to dig into those for easy changes. All of these have been in linux-next for a while with no reported issues.

TTY/Serial driver changes for 5.4-rc1
Even in this age, people are still making new serial port silicon, why... Anyway, here's the TTY and Serial driver update for 5.4-rc1. Lots of changes in here for a number of embedded serial port devices that are being worked on because people really like to see those console logs... Other than that, nothing major here, no core tty changes that anyone should care about. All of these have been in linux-next for a while with no reported issues.

USB changes for 5.4-rc1
Here is the big set of USB patches for 5.4-rc1. Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things. The usual gadget and xhci and usb serial driver updates, along with a bunch of sysfs file cleanups due to the driver core changes to support that. Nothing really major, just constant forward progress. All of these have been in linux-next for a while with no reported issues.
