Linux 5.3 changelog.
This changelog is still not complete. Meanwhile, you can read about Linux 5.3 here:
Or, instead, take a look at the individual pull requests:
1. Virtualization
Add virtio-iommu driver. The virtio IOMMU is a para-virtualized device, allowing to send IOMMU requests such as map/unmap over virtio transport without emulating page tables. This implementation handles ATTACH, DETACH, MAP and UNMAP requests commit
virtio-pmem: Add virtio pmem driver that provides access to virtio-pmem devices, storage devices that are mapped into the physical address space - similar to NVDIMMs - with a virtio-based flushing interface commit
- virtio_net: enable napi_tx by default. NAPI tx mode improves TCP behavior by enabling TCP small queues (TSQ).
TSQ reduces queuing ("bufferbloat") and burstiness commit
vhost: accelerate metadata access. Test shows about 24% improvement on TX PPS commit, commit, commit, commit, commit, commit
vhost_net: disable zerocopy by default commit
veth: introduces bulk XDP_TX in veth. Improves XDP_TX performance by approximately 9% commit
vfio: mdev: Send uevents around parent device registration commit
vmw_balloon: Compaction and shrinker support commit, commit, commit, commit
xen: remove tmem driver commit
2. Cryptography

Make keys and keyrings more namespace aware commit, commit, commit, commit, commit, commit, commit, commit, [https://git.kernel.org/linus/a58946c158a040068e7c94dc1d58bbd273258068|commit]]
Change the permissions model used by keys and keyrings to be based on an ACL commit, commit
Add a keyctl to atomically move a link to a key from one keyring to another commit
Add a keyctl function that requests a set of capability bits to find out what features are supported commit
drbg: add FIPS 140-2 CTRNG for noise source commit
jitter: update implementation to upstream 2.1.2 commit
xxhash: Implement xxhash support. xxhash is a non-cryptographic hash algorithm. Extremely fast, working at speeds close to RAM limits commit
3. Security
Add support for measuring the boot command line during kexec commit, commit, commit
IMA: support for per policy rule template formats commit
TPM: Add support for TCG2 event logs on EFI systems commit, commit, commit, commit
4. Networking
IPv4: Allow 0.0.0.0/8 as a valid address range, allowing for 16m new IPv4 addresses. This is part of an effort to increase the number of available unicast IPv4 addresses commit
User API and initial implementation for nexthop objects, designed to improve the scalability of routes commit, commit, commit, commit, commit, commit,
Enable nexthop objects with IPv4 and IPv6 routes. This is the last part of a long term optimization work, thanks to it a full internet fib (743,799 routes based on a pull in January 2019) can be pushed to the kernel in 4.3 seconds commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Support multipath hashing on inner IP pkts for GRE tunnel commit
IPv4: enable route flushing in network namespaces commit
IPv6: Extend flowlabel_reflect sysctl bitmask to allow conditional reflection of incoming flowlabels in echo replies commit
TCP: add TFO backup key commit, commit, commit, commit, commit, commit
TCP: add optional per socket transmit delay. Adding delays to TCP flows is crucial for studying behavior of TCP stacks commit
Fix listing (IPv4, IPv6) and flushing (IPv6) of cached route exceptions by allowing userspace to clearly request cached routes with the RTM_F_CLONED flag used as a filter (in conjuction with strict checking) and by retrieving and dumping cached routes if requested commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Unix Sockets: Adds the ability for netlink to report a socket's UID along with the commit
Bluetooth: Add support for LE ping feature commit
NFS client: Allow NFS client to set up multiple TCP connections to the server using a new 'nconnect=X' mount option. Queue length is used to balance load commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
batman-adv: Add routable multicast optimizations commit, commit, commit, commit, commit
Netdevice HW MPLS features are not passed from device driver's netdevice to upper netdevice, specifically VLAN and bonding netdevice which are created by the kernel when needed. This prevents enablement and usage of HW offloads. This release inherit the MPLS features from lower netdevices to allow the HW offloads commit, commit
bonding: add an option to specify a delay between peer notifications commit
devlink: To improve visibility of representor netdevice, its association with PF or VF, physical port, two new devlink port flavours are added as PCI PF and PCI VF ports commit, commit, commit, commit, commit
Decoupling PHYLINK from struct net_device commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
dsa: adds support for enabling or disabling the flooding of unknown multicast traffic on the CPU ports commit
- Netfilter
Add support for hardware offloads commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Add native connection tracking support for the bridge. Before this patchset, only chance for people to do stateful filtering is to use the br_netfilter emulation layer, this is a step forward to deprecate it commit, commit, commit, commit, commit, commit, commit, commit, commit
Add SYNPROXY module support in nf_tables. It preserves the behaviour of the SYNPROXY target of iptables but structured in a different way to propose improvements in the future commit
Support to match IPv4 options in nf_tables commit
Support to restore expiration time in set element commit
nft_ct: allow to add, list and delete expectations via nft objref infrastructure and assigning these expectations via nft rule. This allows manual port triggering when no helper is defined to manage a specific protocol commit

Support for bridge pvid matching commit
xt_owner: Add supplementary groups option commit
ipoib: show VF broadcast address commit and correcly show a VF hardware address commit
- ipvs
- mac80211

- RDMA
- Provides dynamic statistics infrastructure using a netlink interface to configure and retrieve those counters. It allows to users monitor various objects by binding
to them counters commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
Delete the ib_ucm module commit
Add support for reporting link state for IP-over-Infiniband net devices commit

Implements the iWARP RDMA transport over the Linux TCP/IP network stack. It enables a system with a standard Ethernet adapter to interoperate with a iWARP adapter or with another system running the SIW driver commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
- Packet scheduler
Introduce tc connection tracking. capabilities in tc sw datapath. It does so via a new tc action, called act_ct, and new tc flower classifier matching on conntrack state, mark and label commit, commit, commit
Introduce act_ctinfo, a new tc filter action module. It is designed to restore DSCPs stored in conntrack marks into the ipv4/v6 diffserv field. The feature is intended for use and has been found useful for restoring ingress classifications based on egress classifications across links that bleach or otherwise change DSCP, typically home ISP Internet links. Restoring DSCP on ingress on the WAN link allows qdiscs such as CAKE to shape inbound packets according to policies that are easier to indicate on egress commit
Introduces a new traffic control action module that allows the manipulation of the MPLS headers of packets. The code impliments functionality including push, pop, and modify commit, commit, commit, commit, commit
