[Bruce Dubbs]

shadow-4.1.5.1 -> shadow-4.2

* general

• Handle libc whose crypt() returns NULL when passed a salt that violates specs or system requirements (e.g. FIPS140). This is needed with glibc/eglibc 2.17 for tools checking passwords (passwd (non PAM enabled) or newgrp), and for tools generating encrypted passwords (chgpasswd, chpasswd, or gpasswd when non PAM enabled or when a fixed crypt method is requested on the command line, and newusers, or passwd in their non PAM enabled versions)
• Fix segfault when reading groups split on multiple lines. This impacts most user/group management tools when MAX_MEMBERS_PER_GROUP is set.

• su
  • When su receives a signal (SIGTERM, or SIGINT/SIGQUIT in non interactive mode), kill the child process group, rather than just the immediate child.
  • Fix segmentation faults for users without a proper home or shell in their passwd entries.

• login
  • Fix segmentation faults for users without a proper home or shell in their passwd entries.

* documentation

• Fixed useradd man page (--home-dir option, instead of --home).

* translation

• Updated Russian translation.
• Updated German man pages translation.
• Fixed gshadow Japanese man page translation.
