Issues like these are best reported to the policy authors and maintainers, but are not impossible to figure out using the analysis tools provided by the setools-console package. Quite often when encountering SELinux denials it will be the case that the operation that is denied is actually allowed in policy, but wasn’t permitted due to a file not being labeled correctly or a process not transitioning to the correct domain.

Using this knowledge, we can follow the same steps to figure out what domains are allowed access to other target types to assist in identifying programs that are running with the wrong context. So based on that we can conclude that the type for content that is read-write by HTTPD domains should be httpd_sys_rw_content_t. A couple of these rules are disabled, but 3 of them are enabled by default.

Those rules are as follows (only accounting for categories, and not MLS security levels) Source dominates the target if the categories in the source context are the same as or a superset of those in the target context. Source and target are equal and dominate each other if the set of categories are the same in each context. A range of categories results in the context being associated with an inclusive set of categories in that range. Source is dominated by the target if the categories in the source context are a subset of the categories of the target context. The compartment part of the above security context is a category range, but can also be a set of categories separated by commas. Understanding how access is computed for two processes with a set of categories requires looking at the dominance rules for SELinux security levels (access is only allowed if the source type’s high security level dominates the target type’s high security level).
