Subject: /etc/init.d/udev: init script leaks file descriptors Package: udev Version: 164-2 File: /etc/init.d/udev Severity: normal
The /etc/init.d/udev script leaks passed file descriptors to
the /sbin/udevd daemon. This causes problems problems for
unattended-upgrades (see #379645). Daemons should generally close all
open file descriptors when starting up.
In this case it is probably easiest to close file descriptors in the
daemon itself. I use this code myself:
/* close all other file descriptors */
m=sysconf(_SC_OPEN_MAX);
/* if the system does not have OPEN_MAX just close the first 32 and
hope we closed enough */
if (m<0)
m=32;
for (i=3;i<m;i++)
close(i);
Thanks.
