RSBAC README for the kernel parameters. --------------------------------------- The RSBAC system accepts the following parameters: - rsbac_debug_ds: Debug messages from the Data Structures component. - rsbac_debug_aef: Debug messages from the enforcement component (AEF). - rsbac_debug_no_adf: Set default log level value for all request types to 0: Do not log. - rsbac_debug_adf (default, so obsolete): Set default log level value for all request types to 1: Logging messages from the decision component (ADF) for all requests that were denied (highly recommended for testing, even in normal use). If provided, pseudonyms of users are used. - rsbac_debug_adf_all: Set default log level value for all request types to 2: Logging messages from the decision component (ADF) for all requests. If provided, pseudonyms of users are used. Gives a real lot of logging stuff - never try this, if checking of sys_syslog is turned on and log levels have not yet been saved to keep them permanent... - rsbac_debug_ds_pm: Debug messages from the Data Structures component, on access to privacy model data. - rsbac_debug_aef_pm: Debug messages for privacy model specific system calls. - rsbac_debug_adf_pm: Debug messages for access control in privacy module. - rsbac_debug_pm: Sets rsbac_debug_ds_pm, rsbac_debug_aef_pm, rsbac_debug_adf_pm (recommended for testing privacy model). - rsbac_debug_adf_ms: Debug messages for access control in Malware Scan. - rsbac_debug_ds_rc: Debug messages from the Data Structures component, on access to Role Compatibility model data. - rsbac_debug_aef_rc: Debug messages for Role Compatibility model specific system calls. - rsbac_debug_adf_rc: Debug messages for access control in RC module. - rsbac_debug_rc: Sets rsbac_debug_ds_rc, rsbac_debug_aef_rc, rsbac_debug_adf_rc. - rsbac_debug_ds_auth: Debug messages from the Data Structures component, on access to AUTH model data. - rsbac_debug_aef_auth: Debug messages for AUTH model specific system calls. - rsbac_debug_adf_auth: Debug messages for access control in AUTH module. - rsbac_debug_auth: Sets rsbac_debug_ds_auth, rsbac_debug_aef_auth, rsbac_debug_adf_auth. - rsbac_debug_ds_acl: Debug messages from the Data Structures component, on access to Access Control Lists (ACL) model data. - rsbac_debug_aef_acl: Debug messages for ACL model specific system calls. - rsbac_debug_adf_acl: Debug messages for access control in ACL module. - rsbac_debug_acl: Sets rsbac_debug_ds_acl, rsbac_debug_aef_acl, rsbac_debug_adf_acl. - rsbac_debug_all: Sets all debug options - in fact turns on a huge amount of logging. Beware of a fast growing system log. Hardly ever recommended. - rsbac_debug_no_write: Turn writing to disk off for this single boot time. For testing. - rsbac_debug_auto: Debug messages from auto-write / rsbacd. Recommended for a good disk saving overview. - rsbac_debug_write: Debug messages from all attribute writing related procedures. - rsbac_no_defaults: suppress creation of default settings, useful for restore from existing backup. Warning: An unconfigured system will only come up in softmode or maint mode, and softmode will produce loads of logging (see rsbac_nosyslog option...). - rsbac_auth_enable_login: Sets auth_may_setuid for /bin/login, if AUTH module is on. A good emergency helper, if you cannot login anymore. - rsbac_softmode (only, if enabled on kernel config): switch to softmode - rsbac_softmode_once (only, if enabled on kernel config): switch to softmode and disallow to switch it on again later - rsbac_softmode_never (only, if softmode enabled on kernel config): disallow to switch softmode on during this runtime - rsbac_softmode_<mod> (module name in lowercase, e.g. rc, only if enabled): switch individual model softmode to on - rsbac_freeze (only, if enabled in kernel config): Disallow RSBAC administration for this runtime. - rsbac_dac_disable (only, if enabled in kernel config): disable Linux DAC - rsbac_nosyslog: do not log to syslog for this boot time - rsbac_no_init_delay: disable delayed init for this single boot (if init delay is enabled in kernel config) - rsbac_delayed_root=major[:minor]: initialize, when this device gets mounted. Omit minor or set to 00 to match all devices with this major number. Delayed init must be enabled in kernel config. - rsbac_auth_learn (only, if enabled in kernel config): enable AUTH learning mode, where AUTH module adds all missing capabilities automatically instead of denying the request. - rsbac_acl_learn and rsbac_acl_learn_fd (only, if enabled in kernel config): enable ACL learning mode for user rights to filesystem objects - rsbac_log_remote_addr=a.b.c.d: Set remote logging address to a.b.c.d - rsbac_log_remote_port=n: Set remote logging port to n. Remote logging must be enabled in kernel config. - rsbac_um_no_excl: Disable exlusive user management for this uptime. - rsbac_daz_ttl=n: Set DAZ cache item ttl to n seconds for this boot. - rsbac_cap_log_missing: Log all calls to capable() for caps, which are not in the process set of effective Linux capabilities, i.e., failed capable() checks. 28/Jan/2005 Amon Ott <ao@rsbac.org>
