Security-Enhanced Linux secures the abrt_upload_watch processes via flexible mandatory access control.
The abrt_upload_watch processes execute with the abrt_upload_watch_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep abrt_upload_watch_t
The abrt_upload_watch_t SELinux type can be entered via the abrt_upload_watch_exec_t file type.
The default entrypoint paths for the abrt_upload_watch_t domain are the following:
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to psbP
Policy governs the access confined processes have to files. SELinux abrt_upload_watch policy is very flexible allowing users to setup their abrt_upload_watch processes in as secure a method as possible.
The following process types are defined for abrt_upload_watch:
Note: semanage permissive -a abrt_upload_watch_t can be used to make the process type abrt_upload_watch_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
SELinux policy is customizable based on least access required. abrt_upload_watch policy is extremely flexible and has several booleans that allow you to manipulate the policy and run abrt_upload_watch with the tightest access possible.
If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.
setsebool -P fips_mode 1
The SELinux process type abrt_upload_watch_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to lsbP
Policy governs the access confined processes have to these files. SELinux abrt_upload_watch policy is very flexible allowing users to setup their abrt_upload_watch processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the abrt_upload_watch, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t abrt_upload_watch_exec_t '/srv/abrt_upload_watch/content(/.*)?'
restorecon -R -v /srv/myabrt_upload_watch_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for abrt_upload_watch:
- Set files with the abrt_upload_watch_exec_t type, if you want to transition an executable to the abrt_upload_watch_t domain.
- Set files with the abrt_upload_watch_tmp_t type, if you want to store abrt upload watch temporary files in the /tmp directories.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
If you want to share files with multiple domains (Apache, FTP, rsync, Samba), you can set a file context of public_content_t and public_content_rw_t. These context allow any of the above domains to read the content. If you want a particular domain to write to the public_content_rw_t domain, you must set the appropriate boolean.
Allow abrt_upload_watch servers to read the /var/abrt_upload_watch directory by adding the public_content_t file type to the directory and by restoring the file type.
semanage fcontext -a -t public_content_t "/var/abrt_upload_watch(/.*)?"
restorecon -F -R -v /var/abrt_upload_watch
Allow abrt_upload_watch servers to read and write /var/abrt_upload_watch/incoming by adding the public_content_rw_t type to the directory and by restoring the file type. You also need to turn on the abrt_upload_watch_anon_write boolean.
semanage fcontext -a -t public_content_rw_t "/var/abrt_upload_watch/incoming(/.*)?"
restorecon -F -R -v /var/abrt_upload_watch/incoming
setsebool -P abrt_upload_watch_anon_write 1
If you want to determine whether abrt-handle-upload can modify public files used for public file transfer services in /var/spool/abrt-upload/., you must turn on the abrt_upload_watch_anon_write boolean.
setsebool -P abrt_upload_watch_anon_write 1
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
