Package: libsepol1
Version: 2.1.4-1
Severity: important
Hello!
After upgrading libsepol1 (2.1.0-1.2 -> 2.1.4-1 , for the record)
I noticed that checkrestart (from the debian-goodies package)
tells me I need to restart init!
# checkrestart
Found 1 processes using old versions of upgraded files
(1 distinct program)
(1 distinct packages)
These processes do not seem to have an associated init script to restart them:
sysvinit:
1 /sbin/init
OK, I cannot trivially restart init, but "telinit u" may be used to tell
init to re-execute itself in place, preserving its state.
But packages that need this to be done after an upgrade usually do it
by themselves in their postinst scripts...
What happened?
First of all, checkrestart confirms that the need to re-execute init
comes from the libsepol1 upgrade:
# checkrestart -v
Found 1 processes using old versions of upgraded files
(1 distinct program)
Process /sbin/init (PID: 1)
List of deleted files in use:
/lib/x86_64-linux-gnu/libsepol.so.1
(1 distinct packages)
These processes do not seem to have an associated init script to restart them:
sysvinit:
1 /sbin/init
Why hasn't libsepol1.postinst managed to re-execute init?
If I understand correctly, the code that is supposed to take care of
this is:
# Final sanity check. Make sure there is a /dev/initctl
# for us to talk to
if [ -e /dev/initctl ]; then
# Use telinit if available, it is better form, according
# to the sysvinit maintainer.
if [ -x /sbin/telinit ]; then
(telinit u ; sleep 1)
else
(init u ; sleep 1)
fi
fi
Well, I don't have any /dev/initctl on any of my boxes!
# ls /dev/ini*
ls: cannot access /dev/ini*: No such file or directory
That's probably the reason why init was not told to re-execute itself.
I don't know what /dev/initctl should be for, but other packages don't
seem to require its presence, in order to tell init to re-execute itself.
For instance, libc6.postinst seems to unconditionally run telinit u:
# Restart init. If it fails, there is nothing we can do, so
# just ignore the error
telinit u 2> /dev/null || true ; sleep 1
Please fix libsepol1.postinst so that it actually tells init to
re-execute itself after an upgrade.
Thanks for your time!
