Re: SElinux issue
Daniel,
on the machine on which things work there is a prewikka.pp file, but on the one that
fails there isn't. On the system
that fails I have the following prewikka policy file (prewikkapol.te):
module prewikka 1.0;
require {
type tmp_t;
type init_var_run_t;
type httpd_prewikka_script_t;
type sysfs_t;
class dir { read search };
}
#============= httpd_prewikka_script_t ==============
allow httpd_prewikka_script_t init_var_run_t:dir search;
allow httpd_prewikka_script_t sysfs_t:dir read;
allow httpd_prewikka_script_t tmp_t:dir read;
and the corresponding prewikkapol.pp file.
On the system that works I have the following prewikka policy file (prewikka.te):
module prewikka 1.0;
require {
type tmp_t;
type init_var_run_t;
type httpd_prewikka_script_t;
type sysfs_t;
class dir { read search };
}
#============= httpd_prewikka_script_t ==============
allow httpd_prewikka_script_t init_var_run_t:dir search;
allow httpd_prewikka_script_t sysfs_t:dir read;
allow httpd_prewikka_script_t tmp_t:dir read;
and the corresponding prewikka.pp file. So as far as I know the prewikka policy files are
present, and neither says
anything about httpd_prewikka_rw_content_t.
Also if I run
semodule -l
the appropriate policy file is shown.
I tried disabling the module:
sudo semodule -d prewikkapol
[sudo] password for pgaltieri:
libsepol.context_from_record: type httpd_prewikka_rw_content_t is not defined (No such
file or directory).
libsepol.context_from_record: could not create context structure (Invalid argument).
libsemanage.validate_handler: invalid context
system_u:object_r:httpd_prewikka_rw_content_t:s0 specified for
/usr/share/prewikka/htdocs/generated_images [all files] (Invalid argument).
libsemanage.dbase_llist_iterate: could not iterate over records (Invalid argument).
semodule: Failed!
I tried to remove the module:
sudo semodule -r prewikkapol
libsepol.context_from_record: type httpd_prewikka_rw_content_t is not defined (No such
file or directory).
libsepol.context_from_record: could not create context structure (Invalid argument).
libsemanage.validate_handler: invalid context
system_u:object_r:httpd_prewikka_rw_content_t:s0 specified for
/usr/share/prewikka/htdocs/generated_images [all files] (Invalid argument).
libsemanage.dbase_llist_iterate: could not iterate over records (Invalid argument).
semodule: Failed!
It does appear though that setsebool still works despite the errors.
Still confused though why I'm seeing the error.
Thanks for the help,
Paolo

Looks like you might have a prewikka policy around?
locate prewikka.pp
Did you build a custom policy module?
