FreeBSD 6.2 manual page repository
FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

#include <bsm/audit.h> int auditon(int cmd, void *data, u_int length);
The auditon system call is used to manipulate various audit control oper‐ ations. *data should point to a structure whose type depends on the com‐ mand. length specifies the size of the data in bytes. cmd may be any of the following: A_SETPOLICY Set audit policy flags. *data must point to a long value set to one of the audit policy control values defined in audit.h. Currently, only AUDIT_CNT and AUDIT_AHLT are implemented. In the AUDIT_CNT case, the action will continue regardless if an event will not be audited. In the AUDIT_AHLT case, a panic(9) will result if an event will not be written to the audit log file. A_SETKAUDIT Return ENOSYS. A_SETKMASK Set the kernel preselection masks (success and failure). *data must point to a au_mask_t structure containing the mask values. These masks are used for non-attributable audit event preselection. A_SETQCTRL Set kernel audit queue parameters. *data must point to a au_qctrl_t structure containing the kernel audit queue control settings: high water, low water, output buffer size, percent min free disk space, and delay (not cur‐ rently used). A_SETSTAT Return ENOSYS. A_SETUMASK Return ENOSYS. A_SETSMASK Return ENOSYS. A_SETCOND Set the current auditing condition. *data must point to a long value containing the new audit condition, one of AUC_AUDITING, AUC_NOAUDIT, or AUC_DISABLED. A_SETCLASS Set the event class preselection mask for an audit event. *data must point to a au_evclass_map_t structure containing the audit event and mask. A_SETPMASK Set the preselection masks for a process. *data must point to a auditpinfo_t structure that contains the given process’s audit preselection masks for both suc‐ cess and failure. A_SETFSIZE Set the maximum size of the audit log file. *data must point to a au_fstat_t structure with the af_filesz field set to the maximum audit log file size. A value of 0 indicates no limit to the size. A_SETKAUDIT Return ENOSYS. A_GETCLASS Return the event to class mapping for the designated audit event. *data must point to a au_evclass_map_t structure. A_GETKAUDIT Return ENOSYS. A_GETPINFO Return the audit settings for a process. *data must point to a auditpinfo_t structure which will be set to contain the audit ID, preselection mask, terminal ID, and audit session ID of the given process. A_GETPINFO_ADDR Return ENOSYS. A_GETKMASK Return the current kernel preselection masks. *data must point to a au_mask_t structure which will be set to the current kernel preselection masks for non- attributable events. A_GETPOLICY Return the current audit policy setting. *data must point to a long value which will be set to one of the current audit policy flags. Currently, only AUDIT_CNT and AUDIT_AHLT are implemented. A_GETQCTRL Return the current kernel audit queue control parame‐ ters. *data must point to a au_qctrl_t structure which will be set to the current kernel audit queue control parameters. A_GETFSIZE Returns the maximum size of the audit log file. *data must point to a au_fstat_t structure. The af_filesz field will be set to the maximum audit log file size. A value of 0 indicates no limit to the size. The af_currsz will be set to the current audit log file size. A_GETCWD Return ENOSYS. A_GETCAR Return ENOSYS. A_GETSTAT Return ENOSYS. A_GETCOND Return the current auditing condition. *data must point to a long value which will be set to the current audit condition, either AUC_AUDITING or AUC_NOAUDIT. A_SENDTRIGGER Send a trigger to the audit daemon. *data must point to a long value set to one of the acceptable trigger val‐ ues: AUDIT_TRIGGER_LOW_SPACE (low disk space where the audit log resides), AUDIT_TRIGGER_OPEN_NEW (open a new audit log file), AUDIT_TRIGGER_READ_FILE (read the audit_control file), AUDIT_TRIGGER_CLOSE_AND_DIE (close the current log file and exit), or AUDIT_TRIGGER_NO_SPACE (no disk space left for audit log file). Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
The auditon() function will fail if: [ENOSYS] Returned by options not yet implemented. [EFAULT] A failure occurred while data transferred to or from the kernel failed. [EINVAL] Illegal argument was passed by a system call. [EPERM] The process does not have sufficient permission to complete the operation. The A_SENDTRIGGER command is specific to the FreeBSD and Mac OS X imple‐ mentations, and is not present in Solaris. audit(2), auditctl(2), getauid(2), setauid(2), getaudit(2), setaudit(2), getaudit_addr(2), setaudit_addr(2), libbsm(3)

The OpenBSM implementation was created by McAfee Research, the security division of McAfee Inc., under contract to Apple Computer Inc. in 2003. It was subsequently adopted by the TrustedBSD Project as the foundation for the OpenBSM distribution.
