Linux 5.17 changelog

Summary:

1. Prominent features

1.1. Support recursive id-mapped mounts

Linux 5.12 added support for id-mapped mounts, that is, creating a mount of an existing file system with the user and group IDs mapped to different ones. This is very useful for containers, where you might want to mount a directory with some random user ID as the user ID expected by the container. This feature, however, required that the base file system was a file system that was not id-mapped itself. This release supports recursive id-mapped mounts.

1.2. BPF CO-RE support and other improvements

The nature of BPF programs makes hard for them to be portable: The position of a member in a data structure can change depending from version to version and even on the same kernel depending on the compiler options. This requires compiling BPF programs in the target computer. In order to make BPF programs more portable, a few features are required; some have already been merged, like BTF, which was introduced in Linux 4.18 and provides type information of all kernel data structures. This release introduces "CO-RE" -Compile Once, Run Everywhere- support. Along with other pieces in the userspace BPF infrastructure, this helps to create BPF programs that can be run in different kernels without requiring compilation.

Recommended article: BPF CO-RE reference guide.

This release also adds the bpf_loop helper, which helps to move loop logic of BPF programs into the kernel and thereby guarantee that the loop will always terminate

4. Memory management

• Batch of memory folio patches 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, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• Segregate a struct slab from struct page 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, commit, commit

• Extend vmalloc support for constrained allocations commit, commit, commit, commit

• Support for anonymous VMA naming. It 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 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); commit, commit, commit

• cgroup

  • memcg: add oom_group_kill memory event when memory.oom.group triggers to allow userspace to cleanly identify when an entire cgroup is oom killed commit * memcg: add per-memcg vmalloc stat commit

  • memcg: better bounds on the memcg stats updates commit

  • hugetlb: add hugetlb.*.numa_stat file commit

• damon

  • schemes: Extend stats for better online analysis and tuning commit, commit, commit, commit, commit, commit

  • Add access checking for hugetlb pages commit

• Adds set_mempolicy_home_node syscall to set a home node for the MPOL_BIND and MPOL_PREFERRED_MANY memory policy. Users should use this syscall after setting up a memory policy for the specified range. The syscall allows specifying a home node/preferred node from which kernel will fulfill memory allocation requests first. This helps applications to hint at a memory allocation preference node and fallback to _only_ a set of nodes if the memory is not available on the preferred node. Fallback allocation is attempted from the node which is nearest to the preferred node commit, commit, commit

• device-dax: Introduce compound pages in devmap in order to minimize 'struct page' overhead commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• sysctl: change watermark_scale_factor max limit to 30% commit

• vmstat: add events for THP max_ptes_* commit

• Improve the migration stats commit, commit, commit

• Migration: support multiple target nodes demotion commit

5. Block layer

• Memory folio support in block + iomap layers commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• md: drop queue limitation for RAID1 and RAID10 commit

• Remove the rsxx driver commit

6. Tracing, perf and BPF

• Add rtla(1) tool, a meta-tool including a set of commands that aims to analyze the real-time properties of Linux. But instead of testing Linux as a black box, rtla leverages kernel tracing capabilities to provide precise information about the properties and root causes of unexpected results. In this release it presents an interface to the osnoise and timerlat tracers. In the future, it will also serve as home to the rtsl and other latency/noise tracers commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

• BPF

  • (FEATURED) BPF CO-RE (COmpile once - Run Everywhere) support commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit, commit

  • (FEATURED) Add bpf_loop helper. One of the complexities of using for loops in bpf programs is that the verifier needs to ensure that in every possibility of the loop logic, the loop will always terminate. As such, there is a limit on how many iterations the loop can do. The bpf_loop helper moves the loop logic into the kernel and can thereby guarantee that the loop will always terminate. The bpf_loop helper simplifies a lot of the complexity the verifier needs to check, as well as removes the constraint on the number of loops able to be run commit, commit, commit, commit

  • Introduce composable BPF types commit, commit, commit, commit, commit, commit, commit, commit, commit

  • Adds unstable conntrack lookup helpers using BPF kfunc support

  • Sleepable local storage commit

  • Add helpers to access traced function arguments commit, commit, commit, commit, commit

  • Support BTF_KIND_TYPE_TAG for btf_type_tag attributes. The main motivation for btf_type_tag is to bring kernel annotations __user, __rcu etc. to btf. With such information available in btf, bpf verifier can detect mis-usages and reject the program. For example, for __user tagged pointer, developers can then use proper helper like bpf_probe_read_kernel() etc. to read the data commit, commit, commit, commit, commit, commit, commit, commit, commit, commit
