NAMEanaconda_selinux − Security Enhanced Linux Policy for the anaconda processes
DESCRIPTIONSecurity-Enhanced Linux secures the anaconda processes via flexible mandatory access control. The anaconda processes execute with the anaconda_t SELinux type. You can check if you have these processes running by executing the ps command with the −Z qualifier. For example: ps -eZ | grep anaconda_t
ENTRYPOINTSThe anaconda_t SELinux type can be entered via the anaconda_exec_t file type. The default entrypoint paths for the anaconda_t domain are the following:
PROCESS TYPESSELinux defines process types (domains) for each process running on the system You can see the context of a process using the −Z option to ps Policy governs the access confined processes have to files. SELinux anaconda policy is very flexible allowing users to setup their anaconda processes in as secure a method as possible. The following process types are defined for anaconda: anaconda_tNote: semanage permissive -a anaconda_t can be used to make the process type anaconda_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANSSELinux policy is customizable based on least access required. anaconda policy is extremely flexible and has several booleans that allow you to manipulate the policy and run anaconda with the tightest access possible. If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default. setsebool -P mmap_low_allowed 1
If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Enabled by default. setsebool -P secure_mode_insmod 1
If you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execheap boolean. Disabled by default. setsebool -P selinuxuser_execheap 1
If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Enabled by default. setsebool -P selinuxuser_execstack 1
MANAGED FILESThe SELinux process type anaconda_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.
file_type all files on the system
COMMANDSsemanage 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.
