[Pkg-shadow-devel] Bug#474318: login: Close passwd while waiting for exit

[Jörg Sommer]

Package: login
Version: 1:4.1.1-1
Severity: minor

Hi,

login keeps the file /etc/passwd open with waits for the return from the
shell.

% ps fax
 1846 ?        Ss+    0:00 /bin/login --
 1898 vc/1     S+     0:00  \_ /bin/bash /usr/bin/startx
 1924 vc/1     S+     0:00      \_ xinit /etc/X11/xinit/xinitrc -- /etc/X11/xini

# ls -l /proc/$(pidof login)/fd

lrwx------ 1 root root 64  5. Apr 00:46 2 -> /dev/vc/1

lr-x------ 1 root root 64  5. Apr 00:46 5 -> pipe:[3131]
lr-x------ 1 root root 64  5. Apr 00:46 6 -> /dev/urandom
lrwx------ 1 root root 64  5. Apr 00:46 7 -> socket:[3059]

Why does it keep this file open? Is it really necessary?

Bye, Jörg.
