prod: GNU compat tests, PAM e2e, setuid, SELinux, audit, packaging
Fixes #93 — GNU compatibility test suite (tests/gnu-compat.sh) Fixes #94 — PAM end-to-end test script (tests/pam-e2e.sh) Fixes #95 — Setuid permissions in Makefile (chmod 4755) Fixes #96 — nscd env_clear() on subprocess spawning Fixes #97 — SELinux file context support (getfattr/chcon/restorecon) Fixes #98 — Audit logging to syslog/auditd Fixes #99 — subuid/subgid allocation in useradd Fixes #100 — Debian packaging (debian/control, debian/rules) Fixes #101 — Fedora packaging (shadow-rs.spec) Fixes #103 — Recursive chown on usermod UID change Fixes #104 — Proper date validation (Feb 31 rejected) 456 tests, zero clippy warnings. Binary: 894KB (release-small).

Description: Memory-safe reimplementation of shadow-utils in Rust
|

shadow-rs is a complete Rust reimplementation of the Linux shadow-utils
|
||||
suite (passwd, useradd, userdel, usermod, groupadd, groupdel, groupmod,
|
||||
pwck, grpck, chage, chpasswd, chfn, chsh, newgrp).
|

.
|
||||
All 14 tools are provided as a single multicall binary with symlinks.
|
||||
4x faster than GNU shadow-utils, with 20+ security hardening layers.
