git_system_selinux − Security Enhanced Linux Policy for the git_system processes
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
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
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.
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 deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by default.
setsebool -P deny_ptrace 1
If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.
setsebool -P domain_fd_use 1
If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. Disabled by default.
setsebool -P domain_kernel_load_modules 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 enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.
setsebool -P global_ssp 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. Disabled 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
If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the git_system_t, you must turn on the authlogin_nsswitch_use_ldap boolean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the git_system_t, you must turn on the kerberos_enabled boolean.
setsebool -P kerberos_enabled 1
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.
