[PATCH 1/1] libsemanage: genhomedircon: consider SEMANAGE_FCONTEXT_DIR in fcontext_matches()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When generating file_contexts.homedirs, libsemanage enumerates the users
on the system and tries to find misconfiguration issues by comparing
their home directories with file contexts defined in the policy. The
comparison is done by fcontext_matches().

Currently this function only operates on file contexts with type ALL,
but it makes sense to also operate on the DIR ones, as a comment states
in the function.

For example on a system with the following entry in /etc/passwd:

    mytestservice:x:2000:100::/var/lib/mytestservice/dir:/bin/bash

and with the following file context definition:

    /var/lib/mytestservice/.* -d gen_context(system_u:object_r:var_lib_t,s0)

"semodule -B" now shows the following warning:

    libsemanage.get_home_dirs: mytestservice homedir
    /var/lib/mytestservice/dir or its parent directory conflicts with a
    file context already specified in the policy.  This usually
    indicates an incorrectly defined system account.  If it is a system
    account please make sure its uid is less than 1000 or greater than
    60000 or its login shell is /sbin/nologin.
