Stunnel linux6/1/2023 ![]() If you want to allow all domains to have the kernel load modules, you must turn on the domain_kernel_load_modules boolean. ![]() If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Setsebool -P daemons_enable_cluster_mode 1 If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. ![]() If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Setsebool -P authlogin_nsswitch_use_ldap 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. stunnel policy is extremely flexible and has several booleans that allow you to manipulate the policy and run stunnel with the tightest access possible. SELinux policy is customizable based on least access required. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. The following process types are defined for stunnel:Ĭan be used to make the process type stunnel_t permissive. SELinux stunnel policy is very flexible allowing users to setup their stunnel processes in as secure a method as possible. Policy governs the access confined processes have to files. You can see the context of a process using the -Z option to psP SELinux defines process types (domains) for each process running on the system The default entrypoint paths for the stunnel_t domain are the following: The stunnel_t SELinux type can be entered via the stunnel_exec_t file type. You can check if you have these processes running by executing the ps command with the -Z qualifier. The stunnel processes execute with the stunnel_t SELinux type.
