๐Ÿ’… samba_bgqd_selinux(8): SELinux Policy for samba_bgqd โœจ

Hey bestie! Youโ€™re looking at the manual page for samba_bgqd_selinux โ€” the SELinux policy page for the samba_bgqd processes. Itโ€™s giving security-core, and weโ€™re gonna walk through it together ๐Ÿซถ


๐ŸŒธ NAME

<pink>samba_bgqd_selinux</pink> โ€” the Security Enhanced Linux Policy for the samba_bgqd processes. Periodt.

โœจ DESCRIPTION

Security-Enhanced Linux secures the samba_bgqd processes via flexible mandatory access control. Like, itโ€™s the bouncer at the club but for processes ๐Ÿ’…

The samba_bgqd processes execute with the samba_bgqd_t SELinux type. Wanna check if youโ€™ve got these processes running? Execute the ps command with the -Z qualifier. For example:

ps -eZ | grep samba_bgqd_t

๐Ÿšช ENTRYPOINTS

The samba_bgqd_t SELinux type can be entered via the samba_bgqd_exec_t file type.

The default entrypoint paths for the samba_bgqd_t domain are the following:

  • /usr/lib/samba/samba-bgqd

๐Ÿ‘‘ PROCESS TYPES

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 ps.

Policy governs the access confined processes have to files. SELinux samba_bgqd policy is very flexible, allowing users to setup their samba_bgqd processes in as secure a method as possible.

The following process types are defined for samba_bgqd:

  • samba_bgqd_t
Note: semanage permissive -a samba_bgqd_t can be used to make the process type samba_bgqd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. Iconic caveat, but donโ€™t forget it ๐Ÿ’€

๐Ÿ”ฎ BOOLEANS

SELinux policy is customizable based on least access required. samba_bgqd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run samba_bgqd with the tightest access possible. Basically, you can tune the vibe check ๐ŸŒˆ

daemons_dontaudit_scheduling โ€” if you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

fips_mode โ€” 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

๐Ÿ“ MANAGED FILES

The SELinux process type samba_bgqd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the processโ€™s UID still needs to have DAC permissions. No skipping that part, bestie ๐Ÿซถ

cluster_conf_t

  • /etc/cluster(/.*)?

cluster_var_lib_t

  • /var/lib/pcsd(/.*)?
  • /var/lib/cluster(/.*)?
  • /var/lib/openais(/.*)?
  • /var/lib/pengine(/.*)?
  • /var/lib/corosync(/.*)?
  • /usr/lib/heartbeat(/.*)?
  • /var/lib/heartbeat(/.*)?
  • /var/lib/pacemaker(/.*)?

cluster_var_run_t

  • /run/crm(/.*)?
  • /run/cman_.*
  • /run/rsctmp(/.*)?
  • /run/aisexec.*
  • /run/heartbeat(/.*)?
  • /run/pcsd-ruby.socket
  • /run/corosync-qnetd(/.*)?
  • /run/corosync-qdevice(/.*)?
  • /run/pcsd.socket
  • /run/corosync.pid
  • /run/cpglockd.pid
  • /run/rgmanager.pid
  • /run/cluster/rgmanager.sk

root_t

  • /sysroot/.aleph-version.json
  • /sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
  • /
  • /initrd
  • /var/lib/ntp

samba_bgqd_var_run_t

  • /run/samba-bgqd.pid

samba_log_t

  • /var/log/samba(/.*)?

samba_var_t

  • /var/nmbd(/.*)?
  • /var/lib/samba(/.*)?
  • /var/cache/samba(/.*)?

๐ŸŽ€ FILE CONTEXTS

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 ls.

Policy governs the access confined processes have to these files. SELinux samba_bgqd policy is very flexible, allowing users to setup their samba_bgqd processes in as secure a method as possible.

๐Ÿงš STANDARD FILE CONTEXT

SELinux defines the file context types for the samba_bgqd. If you wanted to store files with these types in different 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 samba_bgqd_exec_t
'/srv/samba_bgqd/content(/.*)?'
restorecon -R -v /srv/mysamba_bgqd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies know ๐Ÿ’…

The following file types are defined for samba_bgqd:

samba_bgqd_exec_t

  • Set files with the samba_bgqd_exec_t type, if you want to transition an executable to the samba_bgqd_t domain.

samba_bgqd_var_run_t

  • Set files with the samba_bgqd_var_run_t type, if you want to store the samba bgqd files under the /run or /var/run directory.
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. This is important, bestie โ€” temporary vs permanent is not a drill ๐Ÿ˜ญ

๐Ÿ› ๏ธ COMMANDS

  • 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.
