WIP: apache: tag nginx httpd_runtime files #903

apachectl is already marked at httpd_exec_t, so this problem is not specific to nginx. I can make a new domain, like httpd_ctl_t, with associated httpd_ctl_roles. Would that be the preferred way to do this? |
This sounds like the best way forward. |

nginx needs to be executable by system administrators to be able to run various actions, including the critical test option -t. This provides appropriate execution authority to do so. Signed-off-by: Antonio Enrico Russo <[email protected]>

I went forward and created a Indeed, it even wants to open various files (for example, the error log that is, at least on my machine, owned by www-data, and root is not explicitly granted access to it). Therefore, it winds up using dac_override. I suppose we could try to interact with various distributions and upstream to make sure that root is given read access to that file, and then we could remove dac_override from both httpd_t and httpd_ctl_t, but for right now this means that httpd_ctl_t needs quite a bit of permission. |

This should be a non-from interface call from the apache module. The from interfaces are intended for users to use without having to modify the policy sources.

I think this plus especially the port binding makes me reconsider my position...
Overall, I'm beginning to feel this seems too much like httpd_t to make it worthwhile. I'm not definitely saying no, but I'm leaning that direction.
Another option would be to move nginx into a new domain.

So I've been thinking about how to handle this change. Would it make sense to create an attribute httpd_domains that would be common to both nginx and apache? If we opted to do that, should I create a new httpd module for the common parts, and an nginx module for the new domain?

That is a possibility. I'd have to see the full extent of rules that use it.
