I am trying to build an SELinux policy module for a piece of software I am
writing. I used sepolgen to create an initial skeleton policy (running on
Red Hat Enterprise Linux 6). I get the following error when I try and
install the policy:
sudo ./interface.sh
Building and Loading Policy
+ make -f /usr/share/selinux/devel/Makefile
make: Nothing to be done for `all'.
+ /usr/sbin/semodule -i interface.pp

libsepol.sepol_context_to_sid: could not convert dnl to sid

Below is the interface.fc file since I think the error might be in there.

Not sure how to go about debugging this.
Thanks for the help.

Maybe "interface" is a keyword. Could you try another name for the sake
of testing?
The .fc contents look OK to me.
Also make sure that the .fc has a newline at the end ( but i do not
think this is what causes this

So it turns out that the name I used it didn't like and the second name I
used (ui-interface) is also didn't like.
When I tried uiInterface, things started working again. I don't know what
the difference is, but maybe someone can enlighten me as to why the
SELinux policy generation tools don't like things with hyphens in the name?

I suspect that it chokes on "interface". The hyphen might make
ui-interface seem like ui and interface to it or so
interface is used in the m4 macro's (it is a part of what makes selinux
policy modular):

So as long as you avoid keywords like (-)?interface(-)?, (-)?template(-)? (and maybe some others) it may work

I'll see what I can do to fix this situation. I think we should be able to adjust the refpolicy infrastructure to not have these keyword problems since the only macro we really need for processing .fc files is gen_context().

Can you attach all the files libsemanage seems to be complaining about dnl,
but not sure if that is really in one of your files. Also defining context
for usr_t, and httpd_sys_content_t should not be required or should be pushed
to the base httpd package.
- From looking at the file context layout it looks like your app should be
cleaned up to put content into better directories.
