Hi, I've got a Centos 5 box (recently replaced a Centos4 box of the same function). The means of applying custom SELinux policy has changed somewhat from 4->5. I've got it mostly figured out; I have a local.te file with my custom policy and also which defines a few new file types, and a local.fc with appropriate defintions of file contexts. When I run: # checkmodule -M -m -o local.mod local.te # semodule_package -o local.pp -m local.mod # semodule -i local.pp (all in /usr/share/selinux/targeted), the policy gets installed and works properly. However, I can't then use fixfiles or the like to set the custom file contexts (my custom file contexts aren't installed in the main policy). I can apply them manually with chcon, but that's icky and not "The One True Way(tm)".
So, if I do: # checkmodule -M -m -o local.mod local.te # semodule_package -o local.pp -m local.mod -f local.fc # semodule -i local.pp
I get the following output: libsepol.context_from_record: MLS is enabled, but no MLS context found libsepol.context_from_record: could not create context structure libsepol.context_from_string: could not create context structure libsepol.sepol_context_to_sid: could not convert system_u:object_r:file_upload_store_t to sid /etc/selinux/targeted/contexts/files/file_contexts: line 537 has invalid context system_u:object_r:file_upload_store_t libsemanage.semanage_install_active: setfiles returned error code 1.
Where file_upload_store_t is one of my custom types. My local.fc looks like this: /data/spool/blastreq(/.*)? system_u:object_r:blast_req_t /data/spool/blastres(/.*)? system_u:object_r:blast_res_t /data/upload(/.*)? system_u:object_r:file_upload_store_t /data/bfiles(/.*)? system_u:object_r:bfiles_t /var/www/possumbase/html/imagetemp(/.*)? system_u:object_r:http_image_temp_t /var/www/sheep/html/imagetemp(/.*)? system_u:object_r:http_image_temp_t
And my local.te contains (selected portions only for now): module local 1.1;
require { ... <various normal requires> ... } type blast_req_t,file_type; allow httpd_sys_script_t blast_req_t:file { create getattr write}; allow httpd_sys_script_t blast_req_t:dir { read getattr lock search ioctl add_name write }; ...etc
So, looks like I need to do something else, possibly in my local.fc. However, my google-fu is not strong enough to find any actual examples of successful custom file context type creation/installation using selinux modules.
I suspect something simple, but haven't a clue what it is. Anyone got any idea what I need to do different?
Thanks, Craig Miskell
NB: To avoid the whole flamewar: "Turn off SELinux" is not a useful answer in this case ;-)
