SELinux Policy mencoderNAMEmencoderselinux - Security Enhanced Linux Policy for the mencoder processesDESCRIPTIONSecurity-Enhanced Linux secures the mencoder processes via flexible mandatory access control.The mencoder processes execute with the mencodert SELinux type. You can check if you have these processes running by executing the ps com-mand with the -Z qualifier.For example:ps -eZ grep mencodertENTRYPOINTSThe mencodert SELinux type can be entered via the mencoderexect file type.The default entrypoint paths for the mencodert domain are the following:/usr/bin/mencoderPROCESS TYPESSELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psPolicy governs the access confined processes have to files. SELinux mencoder policy is very flexible allowing users tosetup their men-coder processes in as secure a method as possible.The following process types are defined for mencoder:mencodertNote: semanage permissive -a mencodert can be used to make the process type mencodert permissive. SELinux does not deny access to permis-sive process types, but the AVC (SELinux denials) messages are still generated.BOOLEANSSELinux policy is customizable based on least access required. Mencoder policy is extremely flexible and has several booleans that allowyou to manipulate the policy and run mencoder with the tightest access possible.If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executableshould be reported in bugzilla, you must turn on the denyexecmem boolean. Enabled by default.setsebool -P denyexecmem 1If you want to deny any process from ptracing or debugging any other processes, you must turn on thedenyptrace boolean. Enabledbydefault.setsebool -P denyptrace 1If you want to allow all domains to use other domains file descriptors, you must turn on the domainfduse boolean.
Enabled by default.setsebool -P domainfduse 1If youwant to allow all domains to have the kernel load modules, you must turn on the domainkernelloadmodules boolean. Disabled bydefault.setsebool -P domainkernelloadmodules 1If you want to allow all domains to execute in fipsmode, you must turn on the fipsmode boolean. Enabled by default.setsebool -P fipsmode 1If you want to enable reading of urandom for all domains, you must turn on the globalssp boolean. Disabled by default.setsebool -P globalssp 1If you want to determine whether mplayer can make its stack executable, you must turnon the mplayerexecstack boolean.

The paths listed are the defaultpaths forthese file types. Note the processes UID still need to have DAC permissions.cifstmplayerhomet/home/^/./.mplayer(/.)?nfstuserhomet/home/^/./.+usertmpt/var/run/user(/.)?/tmp/hsperfdataroot/var/tmp/hsperfdataroot/tmp/gconfd.FILE CONTEXTSSELinux 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 lsPolicy governsthe access confined processes have to these files. SELinux mencoder policy is very flexible allowing users to setup theirmencoder processes in as secure a method as possible.STANDARD FILE CONTEXTSELinux defines the file context types for the mencoder, if you wanted to store files with these types in a diffent paths, you need to exe-cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.semanage fcontext -a -t mencoderexect '/srv/mencoder/content(/.)?' Restorecon -R -v /srv/mymencodercontentNote: SELinux often uses regular expressions to specify labels that match multiple files.The following file types are defined for mencoder:mencoderexect- Set files with the mencoderexect type, if you want to transition an executable to the mencodert domain.Note: File context can be temporarily modified with the chcon command.If you want to permanently change the file context you need to usethe semanage fcontext command.
