NAME¶

git_system_selinux - Security Enhanced Linux Policy for the git_system processes

DESCRIPTION¶

Security-Enhanced Linux secures the git_system processes via flexible mandatory access control.

The git_system processes execute with the git_system_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 git_system_t

ENTRYPOINTS¶

The git_system_t SELinux type can be entered via the gitd_exec_t file type.

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

/usr/libexec/git-core/git-daemon

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 git_system policy is very flexible allowing users to setup their git_system processes in as secure a method as possible.

The following process types are defined for git_system:

git_system_t

Note: semanage permissive -a git_system_t can be used to make the process type git_system_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS¶

SELinux policy is customizable based on least access required. git_system policy is extremely flexible and has several booleans that allow you to manipulate the policy and run git_system with the tightest access possible.

If you want to determine whether Git system daemon can search home directories, you must turn on the git_system_enable_homedirs boolean. Disabled by default.

setsebool -P git_system_enable_homedirs 1

If you want to determine whether Git system daemon can access cifs file systems, you must turn on the git_system_use_cifs boolean. Disabled by default.

setsebool -P git_system_use_cifs 1

If you want to determine whether Git system daemon can access nfs file systems, you must turn on the git_system_use_nfs boolean. Disabled by default.

setsebool -P git_system_use_nfs 1

If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlogin_nsswitch_use_ldap boolean. Disabled by default.

setsebool -P authlogin_nsswitch_use_ldap 1

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 confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

setsebool -P kerberos_enabled 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

If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

setsebool -P nscd_use_shm 1

If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

setsebool -P use_nfs_home_dirs 1

If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

setsebool -P use_samba_home_dirs 1

MANAGED FILES¶

The SELinux process type git_system_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.

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

/var/run/crm(/.*)?
/var/run/cman_.*
/var/run/rsctmp(/.*)?
/var/run/aisexec.*
/var/run/heartbeat(/.*)?

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.
