The get_map_ranges function shall support the whole accepted range as specified in user_namespaces(7), i.e. upper and lower from 0 to UINT_MAX - 1 as well as range from 1 to UINT_MAX. The actual limit of range depends on values of upper and lower and adding the range to either upper or lower shall never overflow UINT_MAX. Fixes:7c43eb2c4e(2024-07-11, "lib/idmapping.c: get_map_ranges(): Move range check to a2ul() call") Fixes:ff2baed5db(2016-08-14, "idmapping: add more checks for overflow") Fixes:94da3dc5c8(2016-08-14, "also check upper for wrap") Fixes:7f5a14817d(2016-07-31, "get_map_ranges: check for overflow") Co-authored-by: Alejandro Colomar <alx@kernel.org> Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org> Signed-off-by: Alejandro Colomar <alx@kernel.org>
shadow-utils
Introduction
The shadow-utils package includes the necessary programs for converting UNIX password files to the shadow password format, plus programs for managing user and group accounts. The pwconv command converts passwords to the shadow password format. The pwunconv command unconverts shadow passwords and generates a passwd file (a standard UNIX password file). The pwck command checks the integrity of password and shadow files. The lastlog command prints out the last login times for all users. The useradd, userdel, and usermod commands are used for managing user accounts. The groupadd, groupdel, and groupmod commands are used for managing group accounts.
