Bug 1949222

Description of problem:
SELinux is preventing colord from 'map' accesses on the file /var/lib/flatpak/exports/share/mime/mime.cache.

*****  Plugin catchall_boolean (57.6 confidence) suggests   ******************

If you want to allow domain to can mmap files
Then you must tell SELinux about this by enabling the 'domain_can_mmap_files' boolean.

Do
setsebool -P domain_can_mmap_files 1

*****  Plugin catchall_labels (36.2 confidence) suggests   *******************

If you want to allow colord to have map access on the mime.cache file
Then you need to change the label on /var/lib/flatpak/exports/share/mime/mime.cache
Do
# semanage fcontext -a -t FILE_TYPE '/var/lib/flatpak/exports/share/mime/mime.cache'
where FILE_TYPE is one of the following: abrt_helper_exec_t, bin_t, boot_t, cert_t, colord_exec_t, data_home_t, etc_runtime_t, etc_t, file_context_t, fonts_cache_t, fonts_t, gconf_home_t, icc_data_home_t, ifconfig_exec_t, ld_so_cache_t, ld_so_t, lib_t, locale_t, nscd_var_run_t, passwd_file_t, pkcs11_modules_conf_t, policykit_auth_exec_t, prelink_exec_t, shell_exec_t, src_t, sssd_public_t, system_conf_t, system_db_t, systemd_hwdb_etc_t, textrel_shlib_t, user_home_t, user_tmp_t, usr_t, xdm_var_lib_t, xdm_var_run_t.
Then execute:
restorecon -v '/var/lib/flatpak/exports/share/mime/mime.cache'


*****  Plugin catchall (7.64 confidence) suggests   **************************

If you believe that colord should be allowed map access on the mime.cache file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'colord' --raw | audit2allow -M my-colord
# semodule -X 300 -i my-colord.pp
