1. Prominent features
1.1. Faster wine with Syscall User Dispatch
This release adds a clean an efficient mechanism to redirect syscalls to support the non-Linux syscalls of WINE by catching them at syscall entry and redirecting them to the user space emulation. This can be utilized for other purposes as well and has been designed carefully to avoid overhead for the regular fastpath.

1.2. Unprivileged Overlayfs mounts
Overlayfs, merged in Linux 3.18, allows a directory tree (usually read-only) to be overlaid onto another, read-only directory tree, where all the modifications are done.
Use of Overlayfs was limited to privileged users. After auditing the code to make sure that all operations on underlying layers are performed with the privileges of the mounting task, this release finally allows non-privileged users to make use of Overlayfs.
1.3. Support for Intel SGX
Intel SGX is new hardware functionality that can be used by applications to populate protected regions of user code and data called enclaves. Once activated, the new hardware protects enclave code and data from outside access and modification. Enclaves provide a place to store secrets and process data with those secrets (eg, DRM software). SGX implementations have existed on desktop processors for several years. The upcoming 3rd Generation Intel Xeon Scalable Platform, code-named “Ice Lake” will also support SGX.

1.4. Support of new AMD, Intel graphics harware
As part of their policy of providing good Linux support for their hardware, both AMD and Intel have added support for new hardware: AMD has added support for a few new variants (Vangogh, Green Sardine, Dimgrey Cavefish), and Intel has provided better support for DG1.
1.5. Faster performance and better data recover in Btrfs
This release adds a few changes that should improve Btrfs performance in many different areas. First, Btrfs replaced the locking primitive used in the core b-tree implementation. A homegrown locking scheme had been used, but now it uses the standard Linux read-write semaphores; this results in much better performance for highly concurrent workloads. There are also a few changes that significantly improve the throughput/latency of dbench-like workloads.
Aditionally, this release implements new data recovery mount options for people with corrupted file systems. rescue=ignoredatacsums, which ignores faileddata checksums, rescue=ignorebadroots, which attempts to continue mounting the file system in read-only mode even if there are corrupted tree roots, and for convenience a new rescue=all option has been added, which enables 'ignorebadroots', 'ignoredatacsums' and 'nologreplay' at the same time.
1.6. NFS re-exporting support
This release makes NFS re-exporting (exporting a NFS mount via NFS) a first-class feature. This would enable the Linux in-kernel NFS server to be used as an intermediate cache for a remotely-located primary NFS server, for example, even with other NFS server implementations, like a NetApp filer, as the primary. The main interest is in allowing NFSv4.2 (particularly with pnfs) to be reexported via NFSv3.
1.7. Add epoll_pwait2(2) syscall for higher resolution waits
Add epoll_pwait2(2), an epoll_wait(2) variant with nsec resolution that replaces int timeout with struct timespec. It is equivalent otherwise. Use cases such as datacenter networking operate on timescales well below milliseconds. Shorter timeouts bounds their tail latency.
Recommended LWN article: epoll_pwait2(), close_range(), and encoded I/O
1.8. Faster memory leak debugging in ARM
The Linux kernel contains KASAN, a dynamic memory error detector that provides a fast and comprehensive solution for finding use-after-free and out-of-bounds bugs. A more performant and less memory hungry version, software tag-based KASAN, was added in Linux 5.0 for ARM 64 CPUs.
This release implements hardware tag-based KASAN for ARM 64. It relies on arm64 Memory Tagging Extension introduced in ARMv8.5 to perform memory and pointer tagging (instead of shadow memory and compiler instrumentation). While it doesn't removes all the overhead of KASAN, it is significantly faster and memory thrifty than the existing versions, which makes the discovery of memory errors easier.

2. Core (various)
inotify: Increase default inotify.max_user_watches limit to 1048576 commit
locking/rwsem: Rework reader optimistic spinning commit, commit, commit, commit
reboot: allow to specify reboot mode via sysfs commit
(FEATURED) Syscall User Dispatch, a mechanism to quickly disable/enable syscall handling for a specific process and redirect to userspace via SIGSYS commit, commit, commit, commit, commit, commit, commit
proc: Similar to speculation store bypass, show information about the indirect branch speculation mode of a task in /proc/$pid/status commit
Add epoll_pwait2(2) syscall that enables nanosecond timeouts for epoll. Analogous to pselect and ppoll, introduce an epoll_wait syscall variant that takes a struct timespec instead of int timeout commit, commit, commit, commit
- Task scheduler
- Signals
Replace the inefficient signal delivery mode of task work and results in an impressive performance improvement for io_uring commit, commit, commit, commit
Architectures that support address tagging, such as arm64, may want to expose fault address tag bits to the signal handler to help diagnose memory errors. However, these bits have not been previously set, and their presence may confuse unaware user applications. Therefore, introduce a SA_EXPOSE_TAGBITS flag bit in sa_flags that a signal handler may use to explicitly request that the bits are set commit, commit
Define a sa_flags bit which will never be supported in the uapi. The purpose of this flag bit is to allow userspace to distinguish an old kernel that does not clear unknown sa_flags bits from a kernel that supports every flag bit commit, commit, commit, commit
seccomp: Add bitmap cache of constant allow filter results commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- userfaultfd
Add user-mode only option to unprivileged_userfaultfd sysctl knob. When the knob is set to 0, it allows unprivileged users to call userfaultfd, like when it is set to 1, but with the restriction that page faults from only user-mode can be handled. In this mode, an unprivileged user (without SYS_CAP_PTRACE capability) must pass UFFD_USER_MODE_ONLY to userfaultd or the API will fail with EPERM. Recommended LWN article. commit, commit
- io_uring
Allow non-fixed files with SQPOLL commit
Allow SQPOLL with CAP_SYS_NICE privileges commit
Add support for IORING_OP_RENAMEAT commit, commit and IORING_OP_UNLINKAT commit
Add timeout update. Timeout update is a IORING_OP_TIMEOUT_REMOVE request with timeout_flags containing a new IORING_TIMEOUT_UPDATE flag commit, commit
Add timeout support for io_uring_enter(). The big win here is that it allows setups that split SQ and CQ handling into separate threads to avoid locking commit
Add support for shutdown(2), useful for sockets commit
close_range(2): add flag CLOSE_RANGE_CLOEXEC. It sets the close-on-exec bit for the file descriptors instead of close()-ing them commit
fscrypt: Allow deleting files with unsupported encryption policy commit, commit, commit, commit, commit, commit, commit, commit, commit
iommu: Add support to change default domain of commit, commit, commit, commit * Add auxiliary bus support commit

(FEATURED) Performance improvements for dbench alike workloads commit, commit, commit, commit, commit, commit
(FEATURED) Introduce rescue mount option rescue=ignoredatacsums, which ignores data checksums failures (these can actually happen when an application modifies a buffer in-flight when doing an O_DIRECT write) commit
(FEATURED) Introduce rescue mount option rescue=ignorebadroots. It attempts to make read-only mount possible when failing to read corrupted tree roots commit
(FEATURED) Introduce mount option rescue=all, which enables 'ignorebadroots' + 'ignoredatacsums' + 'nologreplay' at the same time commit

Show rescue=usebackuproot in /proc/mounts commit
Free space cache (v1) is loaded asynchronously commit, commit
Remove inode number cache feature commit
- CIFS
Add SYSTEM_SECURITY access flag and use with smb2 when opening files for getting/setting SACLs. Add "system.cifs_ntsd_full" extended attribute to allow user-space access to the functionality. Avoid multiple server calls when setting owner, DACL, and SACL. Add support for getting and setting SACLs commit, commit

- FUSE
- NFS
(FEATURED) Allow NFS filesystems to be reexported. The main interest is in allowing NFSv4.2 (particularly with pnfs) to be reexported via NFSv3 commit, commit, commit, commit, commit, commit
Readdir enhancements: Add support for 1MB readdir RPC calls on-the-wire, modify caching code to ensure that we cache the entire contents of that 1MB call. For filesystems that use ordered readdir cookie schemes (e.g. XFS), it optimises searching for cookies in the client's page cache. Finally, improve scalability when dealing with very large directories by turning off caching when those directories are changing commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Implement support for multiple RPC/RDMA chunks per RPC transaction commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit * NOTIFY
- CEPH
- OVERLAYFS
(FEATURED) Unprivileged mounts commit
Introduce new uuid=off option for inodes index feature. It can be used to replace UUID of the underlying filesystem in file handles with null, and effectively disable UUID checks. This can be useful in case the underlying disk is copied and the UUID of this copy is changed. This is only applicable if all lower/upper/work directories are on the same filesystem, otherwise it will fallback to normal behaviour commit
Add the -o userxattr mount option forces overlayfs to use the "user.overlay." xattr namespace instead of "trusted.overlay.". This is useful for unprivileged mounting of overlayfs commit
- XFS

bpftool: Add {i,d}tlb_misses support for bpftool profile commit
libbpf: add support for generating and deduplicating split BTF. This is an enhancement to the BTF, which allows to designate one BTF as the "base BTF" (e.g., vmlinux BTF), and one or more other BTFs as "split BTF" (e.g., kernel module BTF), which are building upon and extending base BTF with extra types and strings commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- perf
pmu-events: Support event aliasing for system PMUs commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
mem/c2c: Support AUX trace commit, commit, commit, commit, commit, commit, commit, commit, commit
stat: Add --quiet option commit
stat: Support regex pattern in --for-each-cgroup commit
7. Networking
Introduce preferred busy-polling: The existing busy-polling mode, enabled by the SO_BUSY_POLL socket option or the system-wide /proc/sys/net/core/busy_read knob, is opportunistic, when the busy-polling budget is exceeded, the NAPI will be scheduled onto the regular softirq handling. Some applications prefer that most NAPI processing would be done by busy-polling; this release implements such functionality with a new socket option, SO_PREFER_BUSY_POLL commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
IPv6: Add support for the SRv6 End.DT4 and End.DT6 (VRF mode) behavior. The SRv6 End.DT4 behavior is used to implement multi-tenant IPv4 L3 VPNs. It decapsulates the received packets and performs IPv4 routing lookup in the routing table of the tenant. The SRv6 End.DT4 Linux implementation leverages a VRF device in order to force the routing lookup into the associated routing table. The SRv6 End.DT4 behavior is defined in the SRv6 Network Programming commit, commit, commit, commit, commit, commit, commit, commit

packet protocol: make packet_fanout.arr size configurable up to 64K commit
ppp: add PPPIOCBRIDGECHAN and PPPIOCUNBRIDGECHAN ioctls. This new ioctl pair allows two ppp channels to be bridged together: frames arriving in one channel are transmitted in the other channel and vice versa. The practical use for this is primarily to support the L2TP Access Concentrator use-case. The end-user session is presented as a ppp channel (typically PPPoE, although it could be e.g. PPPoA, or even PPP over a serial link) and is switched into a PPPoL2TP session for transmission to the LNS. At the LNS the PPP session is terminated in the ISP's network commit
