3. File systems

• XFS

  • Online fsck support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Switch to use a b+tree to implement the in-core extent list. This reduces the need for a large contiguous allocation that the current indirection array requires, and thus avoids stalls during workloads using giant extent lists (heavily fragmented files), especially on systems that are long running commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• sysctl: make able to disable NUMA stats for improved performance by writting 0 to /proc/sys/vm/numa_stat commit

• Implement synchronous page faults for DAX mappings to make flushing of DAX mappings possible from userspace (through a new mmap(2) flag, MAP_SYNC), so that they can be flushed on finer than page granularity and also avoid the overhead of a syscall commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Switches page table accounting to single counter from three - this removes VmPMD and VmPUD in /proc/self/status commit

• Complete deferred page initialization commit, commit, commit, commit, commit, commit, commit, commit

6. Tracing and perf

• ftrace: Allow module init functions to be traced commit, commit, commit, commit, commit

• tracing: add support for preempt and interrupt enabled/disable events commit, commit

• perf stat: Add generic support for standalone metrics specified in JSON files. A metric is a formula that uses multiple events to compute a higher level result (e.g. IPC) commit

• perf stat: Setting up groups can be complicated due to the complicated scheduling restrictions of different PMUs. Add a concept of a 'weak group': try to set up a group, but if it's not schedulable fallback to not using a group commit

• perf list: Print metric groups with perf list metricgroups commit

• perf record: user registers can currently only collected implicitely with call graph recording. To allow to see them separately, and filter them, add a new --user-regs option to record that is similar to --intr-regs, but acts on user regs. Also teach perf script to print user regs commit, commit

• perf sched timehist: Add --pid and --tid options to show only events for specific pid/tids commit

• tools/kvm_stat: Add Python 3 support to kvm_stat commit

• XEN: grant table interface v2 support commit, commit, commit, commit, commit

• virtio-net: support XDP_REDIRECT commit, commit, commit

8. Cryptography

9. Security

• Add eBPF LSM hooks (see bpf section in networking)
• EVM

  • Extend the /sys/kernel/security/evm interface to allow userspace to signal an RSA key has been loaded. Also allow userspace to block loading of a symmetric key in order to avoid a compromised system from being able to load an additional key type later commit

  • Allow auditd to set pid to 0 to end auditing commit

  • Record fanotify access control decisions commit

• Smack: Base support for overlayfs commit

10. Networking

• TCP

  • Maintain the TCP retransmit queue using an rbtree, with 1GB windows at 100Gb this really has become necessary commit

  • Improve the CPU consumption of the RACK TCP loss recovery algorithm, in particular for high-speed networks commit, commit, commit

  • Remove the forward-acknowledgment (FACK) packet-based loss and reordering detection. FACK has been disabled by default and the successor RACK subsumed FACK and can handle reordering better commit, commit

  • Higher throughput under reordering with adaptive RACK reordering wnd commit

  • New socket option TCP_FASTOPEN_KEY to allow different keys per listener commit

  • Configure TFO without cookie per socket and/or per route. Linux already allows to enable TFO without a cookie by using the fastopen-sysctl and setting it to TFO_SERVER_COOKIE_NOT_REQD (or TFO_CLIENT_NO_COOKIE). This release exposes a socket-option and a per-route attribute to enable such fine-grained configurations commit

  • Add namespace support for the sysctls tcp_abort_on_overflow commit, tcp_adv_win_scale commit, tcp_app_win commit, tcp_autocorking commit, tcp_challenge_ack_limit commit, tcp_default_congestion_control commit, tcp_dsack commit, tcp_early_retrans commit, tcp_fack commit, tcp_frto commit, tcp_invalid_ratelimit commit, tcp_limit_output_bytes commit, tcp_max_reordering commit, tcp_min_rtt_wlen commit, tcp_min_tso_segs commit, tcp_moderate_rcvbuf commit, tcp_nometrics_save commit, tcp_pacing_ca_ratio commit, tcp_pacing_ss_ratio commit, tcp_recovery commit, tcp_retrans_collapse commit, tcp_rfc1337 commit, tcp_rmem and tcp_wmem commit, tcp_slow_start_after_idle commit, tcp_stdurg commit, tcp_thin_linear_timeouts commit, tcp_tso_win_divisor commit, tcp_workaround_signed_windows commit

  • Add support for the new of a new TCP experimental option that is needed by the SMC protocol. With this option, SMC capabilities are exchanged between peers during the TCP three way handshake commit

• IPv4

  • Add namespaces support for the sysctl tcp_fastopen commit, tcp_fastopen_blackhole_timeoutcommit, tcp_fastopen_key commit

  • Send a netevent whenever multipath hash policy is changed commit

• IPv6

  • During route lookup, reader lock is taken and during route insertion, deletion or modification, writer lock is taken. This is a very inefficient implementation because the fastpath always has to do the operation to grab the reader lock. This release tries to get rid of the usage of the rwlock and replace it with rcu and spinlock protection. This greatly speeds up the fastpath performance as it only needs to hold rcu which is much less expensive than grabbing the reader lock commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Implement limits on RFC 8200 Hop-by-Hop and Destination options commit

  • Set all.accept_dad to 0 by default commit

  • Add support for sockopt(SOL_IPV6, IPV6_FREEBIND) commit

  • ila: make identifier format optional commit, commit, commit, commit, commit

  • Add a per-device sysctl (ndisc_tclass) to specify IPv6 Neighbour Discovery traffic class commit

• VSOCK: add the netlink sock_diag interface for AF_VSOCK. Userspace can send a DUMP request to filter sockets based on their state (connected, listening, etc) commit, commit, commit, commit, commit

• BPF

  • Add 'bpftool' utility, to help with the inspection and simple manipulation of eBPF maps (documentation tools/bpf/bpftool

  • Allow BPF programs to get the base RTT of the connection commit, commit, commit, commit, commit

  • New bpf cpumap type for XDP_REDIRECT commit commit, commit, commit, commit

  • eBPF-based device cgroup controller: cgroup v2 lacks the device controller, provided by cgroup v1; this release adds a new eBPF program type, which in combination of previously added ability to attach multiple eBPF programs to a cgroup, will provide a similar functionality, but with some additional flexibility commit, commit, commit, commit, commit

  • New file mode and LSM hooks for eBPF object permission control: eBPF objects are accessed, controlled, and shared via a file descriptor, but unlike file descriptors for files and sockets, the existing mechanisms for eBPF object access control are very limited: grant access to all processes, or only CAP_SYS_ADMIN processes. This release adds LSM hooks to eBPF so that security systems such as selinux can do a more fine grained control commit, commit, commit, commit, commit

  • Extend bpf_{prog,map}_info commit, commit, commit, commit, commit

  • Permit multiple bpf attachments for a single perf tracepoint event commit, commit, commit

  • Enable generic transfer of metadata from XDP into skb, meaning the packet has a flexible and programmable room for meta data, which can later be used by BPF to set various skb members when passing up the stack commit, commit, commit, commit, commit, commit

  • Add support for attaching multiple programs per cgroup commit, commit, commit, commit, commit, commit, commit, commit
