Security-Enhanced Linux secures the setroubleshoot_fixit processes via flexible mandatory access control.
The setroubleshoot_fixit processes execute with the setroubleshoot_fixit_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
ps -eZ | grep setroubleshoot_fixit_t
The setroubleshoot_fixit_t SELinux type can be entered via the setroubleshoot_fixit_exec_t file type.
The default entrypoint paths for the setroubleshoot_fixit_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 setroubleshoot_fixit policy is very flexible allowing users to setup their setroubleshoot_fixit processes in as secure a method as possible.
The following process types are defined for setroubleshoot_fixit:
Note: semanage permissive -a setroubleshoot_fixit_t can be used to make the process type setroubleshoot_fixit_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. setroubleshoot_fixit policy is extremely flexible and has several booleans that allow you to manipulate the policy and run setroubleshoot_fixit 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
If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.
setsebool -P nis_enabled 1
The SELinux process type setroubleshoot_fixit_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 setroubleshoot_fixit policy is very flexible allowing users to setup their setroubleshoot_fixit processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the setroubleshoot_fixit, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t setroubleshoot_fixit_tmpfs_t '/srv/mysetroubleshoot_fixit_content(/.*)?'
restorecon -R -v /srv/mysetroubleshoot_fixit_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for setroubleshoot_fixit:
- Set files with the setroubleshoot_fixit_exec_t type, if you want to transition an executable to the setroubleshoot_fixit_t domain.
- Set files with the setroubleshoot_fixit_tmp_t type, if you want to store setroubleshoot fixit temporary files in the /tmp directories.
- Set files with the setroubleshoot_fixit_tmpfs_t type, if you want to store setroubleshoot fixit files on a tmpfs file system.
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.
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.
