asprintf(3) is non-standard, but is provided by GNU, the BSDs, and musl. That makes it portable enough for us to use. This function is much simpler than the burdensome code for allocating the right size. Being simpler, it's thus safer. I took the opportunity to fix the style to my preferred one in the definitions of variables used in these calls, and also in the calls to free(3) with these pointers. That isn't gratuituous, but has a reason: it makes those appear in the diff for this patch, which helps review it. Oh, well, I had an excuse :) Reviewed-by: Iker Pedrosa <ipedrosa@redhat.com> 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.
