mm: add a field to store names for private anonymous memory
In many userspace applications, and especially in VM based applications like Android uses heavily, there are multiple different allocators in use. At a minimum there is libc malloc and the stack, and in many cases there are libc malloc, the stack, direct syscalls to mmap anonymous memory, and multiple VM heaps (one for small objects, one for big objects, etc.). Each of these layers usually has its own tools to inspect its usage; malloc by compiling a debug version, the VM through heap inspection tools, and for direct syscalls there is usually no way to track them. On Android we heavily use a set of tools that use an extended version of the logic covered in Documentation/vm/pagemap.txt to walk all pages mapped in userspace and slice their usage by process, shared (COW) vs. unique mappings, backing, etc. This can account for real physical memory usage even in cases like fork without exec (which Android uses heavily to share as many private COW pages as possible between processes), Kernel SamePage Merging, and clean zero pages. It produces a measurement of the pages that only exist in that process (USS, for unique), and a measurement of the physical memory usage of that process with the cost of shared pages being evenly split between processes that share them (PSS). If all anonymous memory is indistinguishable then figuring out the real physical memory usage (PSS) of each heap requires either a pagemap walking tool that can understand the heap debugging of every layer, or for every layer's heap debugging tools to implement the pagemap walking logic, in which case it is hard to get a consistent view of memory across the whole system. Tracking the information in userspace leads to all sorts of problems. It either needs to be stored inside the process, which means every process has to have an API to export its current heap information upon request, or it has to be stored externally in a filesystem that somebody needs to clean up on crashes. It needs to be readable while the process is still running, so it has to have some sort of synchronization with every layer of userspace. Efficiently tracking the ranges requires reimplementing something like the kernel vma trees, and linking to it from every layer of userspace. It requires more memory, more syscalls, more runtime cost, and more complexity to separately track regions that the kernel is already tracking. This patch adds a field to /proc/pid/maps and /proc/pid/smaps to show a userspace-provided name for anonymous vmas. The names of named anonymous vmas are shown in /proc/pid/maps and /proc/pid/smaps as [anon:<name>]. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name) Setting the name to NULL clears it. The name length limit is 80 bytes including NUL-terminator and is checked to contain only printable ascii characters (including space), except '[',']','\','$' and '`'. Ascii strings are being used to have a descriptive identifiers for vmas, which can be understood by the users reading /proc/pid/maps or /proc/pid/smaps. Names can be standardized for a given system and they can include some variable parts such as the name of the allocator or a library, tid of the thread using it, etc. The name is stored in a pointer in the shared union in vm_area_struct that points to a null terminated string. Anonymous vmas with the same name (equivalent strings) and are otherwise mergeable will be merged. The name pointers are not shared between vmas even if they contain the same name. The name pointer is stored in a union with fields that are only used on file-backed mappings, so it does not increase memory usage. CONFIG_ANON_VMA_NAME kernel configuration is introduced to enable this feature. It keeps the feature disabled by default to prevent any additional memory overhead and to avoid confusing procfs parsers on systems which are not ready to support named anonymous vmas. The patch is based on the original patch developed by Colin Cross, more specifically on its latest version [1] posted upstream by Sumit Semwal. It used a userspace pointer to store vma names. In that design, name pointers could be shared between vmas. However during the last upstreaming attempt, Kees Cook raised concerns [2] about this approach and suggested to copy the name into kernel memory space, perform validity checks [3] and store as a string referenced from vm_area_struct. One big concern is about fork() performance which would need to strdup anonymous vma names. Dave Hansen suggested experimenting with worst-case scenario of forking a process with 64k vmas having longest possible names [4]. I ran this experiment on an ARM64 Android device and recorded a worst-case regression of almost 40% when forking such a process. This regression is addressed in the followup patch which replaces the pointer to a name with a refcounted structure that allows sharing the name pointer between vmas of the same name. Instead of duplicating the string during fork() or when splitting a vma it increments the refcount.

Note that assigning an attribute to a virtual memory area might prevent it from being merged with adjacent virtual memory areas due to the difference in that attribute's value. Currently, arg2 must be one of: PR_SET_VMA_ANON_NAME Set a name for anonymous virtual memory areas. arg5 should be a pointer to a null-terminated string containing the name. The name length including null byte cannot exceed 80 bytes. If arg5 is NULL, the name of the appropriate anonymous virtual memory areas will be reset. The name can contain only printable ascii characters (including space), except '[',']','\','$' and '`'.

sound updates for 5.17-rc1
It's a relatively calm development cycle, but still lots of updates in the driver side like Intel SOF. Below are some highlights: * ALSA / ASoC core: - A new kselftest for ALSA control API - PCM NO_REWINDS support - Potential race fixes around control removals - Unify x86 SG-buffer memory allocation code - Cleanups and race fixes for ASoC DPCM locking * ASoC: - Refinements and cleanups around the delay() APIs - Wider use of dev_err_probe(). - Continuing cleanups and improvements to the SOF code - Support for pin switches in simple-card derived cards - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20 S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments TLV320ADC3xxx * HD-audio / USB-audio: - Fix deadlock at HD-audio codec unbinding - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device * Misc: - Fix virmidi drain behavior Note that the merge of CS35L41 codec support is still half-baked, and at least one ACPI change is missing.

Most of the changes are under the hood, but there are some minor user visible improvements and several performance improvements too. Features: - make send work with concurrent block group relocation. We're not allowed to prevent send failing or silently producing some bad stream but with more fine grained locking and checks it's possible. The send vs deduplication exclusion could reuse the same logic in the future. - new exclusive operation 'balance paused' to allow adding a device to filesystem with paused balance - new sysfs file for fsid stored in the per-device directory to help distinguish devices when seeding is enabled, the fsid may differ from the one reported by the filesystem Performance improvements: - less metadata needed for directory logging, directory deletion is 20-40% faster - in zoned mode, cache zone information during mount to speed up repeated queries (about 50% speedup) - free space tree entries get indexed and searched by size (latency -30%, search run time -30%) - less contention in tree node locking when inserting a key and no splits are needed (files/sec in fsmark improves by 1-20%) Fixes: - fix ENOSPC failure when attempting direct IO write into NOCOW range - fix deadlock between quota enable and other quota operations - global reserve minimum calculations fixed to account for free space tree - in zoned mode, fix condition for chunk allocation that may not find the right zone for reuse and could lead to early ENOSPC Core: - global reserve stealing got simplified and cleaned up in evict - remove async transaction commit based on manual transaction refs, reuse existing kthread and mechanisms to let it commit transaction before timeout - preparatory work for extent tree v2, add wrappers for global tree roots, truncation path cleanups - remove readahead framework, it's a bit overengineered and used only for scrub, and yet it does not cover all its needs, there is another readahead built in the b-tree search that is now used, performance drop on HDD is about 5% which is acceptable and scrub is often throttled anyway, on SSDs there's no reported drop but slight improvement - self tests report extent tree state when error occurs - replace assert with debugging information when an uncommitted transaction is found at unmount time Other: - error handling improvements - other cleanups and refactoring" * tag 'for-5.17-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (115 commits) btrfs: output more debug messages for uncommitted transaction btrfs: respect the max size in the header when activating swap file btrfs: fix argument list that the kdoc format and script verified btrfs: remove unnecessary parameter type from compression_decompress_bio btrfs: selftests: dump extent io tree if extent-io-tree test failed btrfs: scrub: cleanup the argument list of scrub_stripe() btrfs: scrub: cleanup the argument list of scrub_chunk() btrfs: remove reada infrastructure btrfs: scrub: use btrfs_path::reada for extent tree readahead btrfs: scrub: remove the unnecessary path parameter for scrub_raid56_parity() btrfs: refactor unlock_up btrfs: skip transaction commit after failure to create subvolume btrfs: zoned: fix chunk allocation condition for zoned allocator btrfs: add extent allocator hook to decide to allocate chunk or not btrfs: zoned: unset dedicated block group on allocation failure btrfs: zoned: drop redundant check for REQ_OP_ZONE_APPEND and btrfs_is_zoned btrfs: zoned: sink zone check into btrfs_repair_one_zone btrfs: zoned: simplify btrfs_check_meta_write_pointer btrfs: zoned: encapsulate inode locking for zoned relocation btrfs: sysfs: add devinfo/fsid to retrieve actual fsid from the device ... |

drm/amdkfd: make SPDX License expression more sound
Commit b5f57384805a ("drm/amdkfd: Add sysfs bitfields and enums to uAPI") adds include/uapi/linux/kfd_sysfs.h with the "GPL-2.0 OR MIT WITH Linux-syscall-note" SPDX-License expression. The command ./scripts/spdxcheck.py warns: include/uapi/linux/kfd_sysfs.h: 1:48 Exception not valid for license MIT: Linux-syscall-note For a uapi header, the file under GPLv2 License must be combined with the Linux-syscall-note, but combining the MIT License with the Linux-syscall-note makes no sense, as the note provides an exception for GPL-licensed code, not for permissively licensed code. So, reorganize the SPDX expression to only combine the note with the GPL License condition. This makes spdxcheck happy again.

gro: add ability to control gro max packet size
Eric Dumazet suggested to allow users to modify max GRO packet size. We have seen GRO being disabled by users of appliances (such as wifi access points) because of claimed bufferbloat issues, or some work arounds in sch_cake, to split GRO/GSO packets. Instead of disabling GRO completely, one can chose to limit the maximum packet size of GRO packets, depending on their latency constraints. This patch adds a per device gro_max_size attribute that can be changed with ip link command. ip link set dev eth0 gro_max_size 16000 Suggested-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Coco Li <lixiaoyan@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

can: netlink: report the CAN controller mode supported flags
Currently, the CAN netlink interface provides no easy ways to check the capabilities of a given controller. The only method from the command line is to try each CAN_CTRLMODE_* individually to check whether the netlink interface returns an -EOPNOTSUPP error or not (alternatively, one may find it easier to directly check the source code of the driver instead...) This patch introduces a method for the user to check both the supported and the static capabilities. The proposed method introduces a new IFLA nest: IFLA_CAN_CTRLMODE_EXT which extends the current IFLA_CAN_CTRLMODE. This is done to guaranty a full forward and backward compatibility between the kernel and the user land applications. The IFLA_CAN_CTRLMODE_EXT nest contains one single entry: IFLA_CAN_CTRLMODE_SUPPORTED. Because this entry is only used in one direction: kernel to userland, no new struct nla_policy are introduced.

nl80211: clarify comment for mesh PLINK_BLOCKED state
When a mesh link is in blocked state, it is very useful to still allow auth requests from the peer to re-establish it. When a remote node is power cycled, the peer state can easily end up in blocked state if multiple auth attempts are performed. Since this can lead to several minutes of downtime, we should accept auth attempts of the peer after it has come back.

btrfs: remove no longer needed logic for replaying directory deletes
Now that we log only dir index keys when logging a directory, we no longer need to deal with dir item keys in the log replay code for replaying directory deletes. This is also true for the case when we replay a log tree created by a kernel that still logs dir items. So remove the remaining code of the replay of directory deletes algorithm that deals with dir item keys.

habanalabs: change wait_for_interrupt implementation
Currently the cq counters are allocated in userspace memory, and mapped by the driver to the device address space. A new requirement that is part of new future API related to this one, requires that cq counters will be allocated in kernel memory. We leverage the existing cb_create API with KERNEL_MAPPED flag set to allocate this memory. That way we gain two things: 1. The memory cannot be freed while in use since it's protected by refcount in driver. 2. No need to wake up the user thread upon each interrupt from CQ, because the kernel has direct access to the counter. Therefore, it can make comparison with the target value in the interrupt handler and wake up the user thread only if the counter reaches the target value. This is instead of waking the thread up to copy counter value from user then go sleep again if target value wasn't reached.

Retrieve information about last CS timeout. 3. Retrieve information about last razwi error. This information doesn't contain user data, so no danger of data leakage between users.

xfrm: rate limit SA mapping change message to user space
Kernel generates mapping change message, XFRM_MSG_MAPPING, when a source port chage is detected on a input state with UDP encapsulation set. Kernel generates a message for each IPsec packet with new source port. For a high speed flow per packet mapping change message can be excessive, and can overload the user space listener. Introduce rate limiting for XFRM_MSG_MAPPING message to the user space. The rate limiting is configurable via netlink, when adding a new SA or updating it. Use the new attribute XFRMA_MTIMER_THRESH in seconds. v1->v2 change: update xfrm_sa_len() v2->v3 changes: use u32 insted unsigned long to reduce size of struct xfrm_state fix xfrm_ompat size Reported-by: kernel test robot <lkp@intel.com> accept XFRM_MSG_MAPPING only when XFRMA_ENCAP is present Co-developed-by: Thomas Egerer <thomas.egerer@secunet.com> Signed-off-by: Thomas Egerer <thomas.egerer@secunet.com> Signed-off-by: Antony Antony <antony.antony@secunet.com> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> |
