NAME¶

git_session_selinux - Security Enhanced Linux Policy for the git_session processes

DESCRIPTION¶

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

The git_session processes execute with the git_session_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_session_t

ENTRYPOINTS¶

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

The default entrypoint paths for the git_session_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_session policy is very flexible allowing users to setup their git_session processes in as secure a method as possible.

The following process types are defined for git_session:

git_session_t

Note: semanage permissive -a git_session_t can be used to make the process type git_session_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_session policy is extremely flexible and has several booleans that allow you to manipulate the policy and run git_session with the tightest access possible.

If you want to determine whether Git session daemon can bind TCP sockets to all unreserved ports, you must turn on the git_session_bind_all_unreserved_ports boolean. Disabled by default.

setsebool -P git_session_bind_all_unreserved_ports 1

If you want to determine whether calling user domains can execute Git daemon in the git_session_t domain, you must turn on the git_session_users boolean. Disabled by default.

setsebool -P git_session_users 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 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 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_session_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.

krb5_host_rcache_t

/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

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.
