1. Block layer

• loop: Add LOOP_CONFIGURE ioctl. This allows userspace to completely setup a loop device with a single ioctl, removing the in-between state where the device can be partially configured commit

• Add support for Inline Encryption to the block layer. Inline Encryption hardware allows software to specify an encryption context (an encryption key, crypto algorithm, data unit num, data unit size, etc.) along with a data transfer request to a storage device, and the inline encryption hardware will use that context to en/decrypt the data. The inline encryption hardware is part of the storage device, and it conceptually sits on the data path between system memory and the storage device commit, commit, commit, commit, commit

• Device Mapper

  • dm crypt: support using encrypted keys commit

  • Add emulated block size target. Its main purpose is to emulate 512 byte sectors on 4K native disks commit

  • dma-zoned: Add a new metadata version 2, which brings the following improvements: UUIDs and labels, extend random zones by an additional regular disk device, and tertiary superblock support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • dm mpath: add Historical Service Time Path Selector. It keeps an exponential moving average of the service time for each path, and uses this along with the number of inflight requests to estimate future service time for a path commit

  • dm ebs: pass discards down to underlying device commit

  • dm bufio: implement discard commit

  • dm writecache: improve performance on DDR persistent memory (Optane) commit

  • dm-zoned: improve cache performance commit, commit, commit, commit, commit, commit

  • dm-zoned: multiple drive support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Add support for RADOS compressible/incompressible allocation hints commit, commit

• bcache: asynchronous devices registration commit, commit

2. Tracing, perf and BPF

• BPF

  • Introduce CAP_BPF to split BPF operations that are allowed under CAP_SYS_ADMIN into combination of CAP_BPF, CAP_PERFMON, CAP_NET_ADMIN and keep some of them under CAP_SYS_ADMIN. The user process has to have: CAP_BPF to create maps and do other sys_bpf() commands, CAP_BPF and CAP_PERFMON to load tracing programs, and CAP_BPF plus CAP_NET_ADMIN to load networking programs commit, commit, commit

  • bpftool: Allow probing for CONFIG_HZ from kernel config commit

  • Implement a new BPF ring buffer, as presented at BPF virtual conference. It presents an alternative to perf buffer, following its semantics closely, but allowing sharing same instance of ring buffer across multiple CPUs efficiently commit, commit, commit, commit, commit

  • The bpf iterator provides in-kernel aggregation abilities for kernel data. This can greatly improve performance compared to e.g., iterating all process directories under /proc commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Allow any port in bpf_bind helper commit, commit, commit, commit

  • Enable BPF programs to fetch sockets from SOCKMAP/SOCKHASH by doing a map lookup commit, commit, commit

  • Allow a bunch of existing sk lookup and skb cgroup id helpers, and adds two new bpf_sk_{,ancestor_}cgroup_id helpers to be used in cgroup skb programs commit, commit, commit, commit, commit

• IPv6: Implement the upcoming rev of RFC4941 (IPv6 temporary addresses) commit

• netlink: add infrastructure to expose policies to userspace commit

• namespaces: enable to inherit devconf from current namespace. The goal is to be able to inherit the initial devconf parameters from the current netns, ie the netns where this new netns has been created. This is useful in a containers environment where /proc/sys is read only. For example, if a pod is created with specifics devconf parameters and has the capability to create netns, the user expects to get the same parameters than his 'init_net', which is not the real init_net in this case commit

• Fixes for SRBDS security issue. SRBDS is an MDS-like speculative side channel that can leak bits from the random number generator (RNG) across cores and threads. New microcode serializes the processor access during the execution of RDRAND and RDSEED. This ensures that the shared buffer is overwritten before it is released for reuse. This is equivalent to a full bus lock, which means that many threads running the RNG instructions in parallel have the same effect as the same amount of threads issuing a locked instruction targeting an address which requires locking of two cachelines at once commit, commit, commit, commit
