Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.13.1-85.fc21.noarch

How reproducible:
Every time

Steps to Reproduce:
1. Build custom Xfce live DVD

Actual results:
rpm --verify selinux-policy-targeted shows
"missing     /etc/selinux/targeted/modules/active/modules/vbetool.pp"
Above error message

Expected results:
No errors or missing files

Additional info:

I fixed the vbetool problem.

I see this type in rawhide policy

Comment 2 Miroslav Grepl 2014-10-13 08:56:47 UTC
It works for me on my F21.

What does

# yum reinstall selinux-policy

portion of livecd-creator chroot output

yum reinstall failed because there's no repository available in livecd-creator chroot. I copied the rpm to INSTALL_ROOT from outside the shell. As this attachment shows, yum reinstall, pointing to this rpm, works normally.

Comment 4 Peter H. Jones 2014-10-21 08:53:59 UTC
With selinux-policy-targeted-3.13.1-86.fc21.noarch, I get:
rpm --verify selinux-policy-targeted-3.13.1-86.fc21.noarch gives
"missing     /etc/selinux/targeted/modules/active/modules/vbetool.pp",
but rpm -ql selinux-policy-targeted-3.13.1-86.fc21.noarch shows it in the list!

grep -n networkd /etc/selinux/targeted/contexts/files/file_contexts^ gives:
"2284:/var/run/systemd/netif(/.*)?       system_u:object_r:systemd_networkd_var_run_t:s0^
5502:/usr/lib/systemd/systemd-networkd  --      system_u:object_r:systemd_networkd_exec_t:s0^
5706:/usr/lib/systemd/system/systemd-networkd\.service  system_u:object_r:systemd_networkd_unit_file_t:s0^"

Just before livecd-creator exits to the chroot shell, I now get:
"/etc/selinux/targeted/contexts/files/file_contexts: has invalid context system_u:object_r:systemd_networkd_var_run_t:s0".

Furthermore, I need the following .te files to allow me to login to my custom live build:
"$ cat kernel0000.te

module kernel0000 0.0.0.0;

require {
	type unconfined_t;
	type kernel_t;
	class process transition;
}

#============= kernel_t ==============
allow kernel_t unconfined_t:process transition;
bash-4.2$ cat login0000.te

module login0000 0.0.0.0;

require {
	type unconfined_t;
	type root_t;
	class file entrypoint;
}

#============= unconfined_t ==============
allow unconfined_t root_t:file entrypoint;
"

If I disable either, and try to log out and log in, I get an AVC alert.

If that's a separate bug, I'm willing to file it as such.

I still have the problem with selinux-policy-3.13.1-88.fc21.noarch and selinux-policy-targeted-3.13.1-88.fc21.noarch:
missing vbetool and invalid context message.

Comment 9 Peter H. Jones 2014-10-26 00:31:58 UTC
Still have the problem with selinux-policy-3.13.1-91.fc21 in a custom live build.

To reiterate:

1. rpm --verify selinux-policy complains about missing vbetool.pp. Also, trying to list the files in rpm -ql selinux-policy shows other missing files. Perhaps these are optional, hence not loaded.

2. In order boot, I need two .te files. I install these during the build phase.
If I disable either, I get a recommendation to reinstall and enable the same .te
(diff shows only the name of the .te is different).

I don't mind having to add these files, but I'd like to be sure using them would not create a security risk if I give my build to a final user.


Here are the files I am using:

kernel0000.te:

module kernel0000 0.0.0.0;

require {
	type unconfined_t;
	type kernel_t;
	class process transition;
}

#============= kernel_t ==============
allow kernel_t unconfined_t:process transition;


login0000.te:

module login0000 0.0.0.0;

require {
	type unconfined_t;
	type root_t;
	class file entrypoint;
}

#============= unconfined_t ==============
allow unconfined_t root_t:file entrypoint;


3. To build, I used the following FC21 packages on a FC20 system. I think I got an unbootable DVD when I tried to use the FC20 versions, but I will carefully reinstall the FC20 versions and repeating the FC20 test. As this is a new system, I'd like to target FC21.

The FC21's I had were:
python-imgcreate-21.3-1.fc21.x86_64
lorax-21.26-1.fc21.x86_64
syslinux-extlinux-nonlinux-6.03-1.fc21.noarch
syslinux-6.03-1.fc21.x86_64
pykickstart-1.99.63-2.fc21.noarch
syslinux-extlinux-6.03-1.fc21.x86_64
livecd-tools-21.3-1.fc21.x86_64
syslinux-nonlinux-6.03-1.fc21.noarch .

Comment 13 Peter H. Jones 2014-10-26 02:16:55 UTC
Tried building on a FC20 system. In other words,
python-imgcreate-21.3-1.fc21.x86_64 was replaced with python-imgcreate-20.5-1.fc20.x86_64
lorax-21.26-1.fc21.x86_64 was replaced with lorax-20.5-1.fc20.x86_64
syslinux-extlinux-nonlinux-6.03-1.fc21.noarch was replaced with (nothing)
syslinux-6.03-1.fc21.x86_64 was replaced with syslinux-4.05-7.fc20.x86_64
pykickstart-1.99.63-2.fc21.noarch was replaced with pykickstart-1.99.48-1.fc20.noarch
syslinux-extlinux-6.03-1.fc21.x86_64 was replaced with syslinux-extlinux-4.05-7.fc20.x86_64
livecd-tools-21.3-1.fc21.x86_64 was replaced with livecd-tools-20.5-1.fc20.x86_64
syslinux-nonlinux-6.03-1.fc21.noarch was replaced with (nothing)

When I tried to boot the resulting DVD image, I got an ISOLINUX 6.03 identification message, followed by a "Faild to load ldlinux.c32".

I also got the invalid contexts message.

Comment 14 Fedora Update System 2014-10-28 21:49:53 UTC
selinux-policy-3.13.1-90.fc21 has been pushed to the Fedora 21 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 15 David Tonhofer 2015-01-11 21:11:28 UTC
On an EC2 instance: 

$ rpm --verify selinux-policy-targeted-3.13.1-103.fc21.noarch

missing /etc/selinux/targeted/modules/active/modules/vbetool.pp
