履歴

プロジェクトの歴史と使われ方

keyutils is the user-space utility and library package for the Linux kernel key retention service. It provides tools such as keyctl, request-key, and key.dns_resolver, plus libkeyutils for programs that need to call the kernel key-management interfaces.

プロジェクトの歴史

David Howells created the keyutils package in July 2005, shortly after the Linux key-management facility became a user-visible subsystem. The package grew from command-line control utilities into a split utility, runtime-library, and development-header package with manual pages and request-key integration.

The keyutils spec changelog shows a long maintenance arc tied to kernel capabilities: version 1.0 in November 2005 renamed the library/header to keyutils and introduced library symbol versioning; version 1.3 in February 2010 exposed security-context and parent-session-keyring operations; version 1.5 in March 2011 added KEYCTL_REJECT, KEYCTL_INSTANTIATE_IOV, DNS lookup generalization, and more keyctl commands; version 1.6 in November 2018 added public-key operations that required Linux 4.20.

採用の歴史

keyutils is packaged broadly because it is glue for Linux authentication, filesystem, DNS, and crypto-adjacent workflows rather than an optional application. The batch metadata records packages in Alpine, Homebrew, Debian, Fedora, Nix, Arch, Ubuntu, and openSUSE/Zypper ecosystems.

The Linux kernel documentation describes keyrings as a kernel service for caching cryptographic keys, authentication tokens, cross-domain user mappings, and related data for filesystems and kernel services. keyutils is the standard user-space companion for inspecting and operating on that facility.

使われ方

Administrators and system services use keyctl to add, link, search, read, invalidate, and manage keys and keyrings. request-key is invoked by the kernel-side request-key callback path when a key must be instantiated in user space, and key.dns_resolver supports DNS-related upcalls.

パッケージ好きにとっての重要性

keyutils is a classic small package with outsized system importance: it exposes kernel ABI surfaces, ships a shared library and manual pages, and changes as the Linux key subsystem adds capabilities. It is the kind of package that may be invisible on a workstation until Kerberos, encrypted filesystems, DNS resolver keys, module signing, or request-key upcalls need it.

タイムライン

  • 2005-07-12: keyutils package creation.
  • 2005-11-28: version 1.0 renamed the library and header to keyutils and added symbol versioning.
  • 2011-03-10: version 1.5 added newer keyctl functionality including KEYCTL_REJECT and KEYCTL_INSTANTIATE_IOV.
  • 2018-11-13: version 1.6 added public-key operations requiring Linux 4.20.
  • 2020-07-07: version 1.6.3 adjusted key change notifications to use pipe2(O_NOTIFICATION_PIPE).

Related projects

  • The Linux kernel key retention service is the kernel-side subsystem. Linux man-pages documents many of the system-call interfaces, while request-key and key.dns_resolver are user-space helpers shipped in keyutils.
