MAC_BSDEXTENDED(4) BSD Kernel Interfaces Manual MAC_BSDEXTENDED(4) NAME mac_bsdextended -- file system firewall policy SYNOPSIS To compile the file system firewall policy into your kernel, place the following lines in your kernel configuration file: options MAC options MAC_BSDEXTENDED Alternately, to load the file system firewall policy module at boot time, place the following line in your kernel configuration file: options MAC and in loader.conf(5): mac_bsdextended_load="YES" DESCRIPTION The mac_bsdextended interface provides an interface for the system admin- istrator to impose mandatory rules regarding users and some system ob- jects. Rules are uploaded to the module (typically using ugidfw(8), or some other tool utilizing libugidfw(3)) where they are stored internally and used to determine whether to allow or deny specific accesses (see ugidfw(8)). IMPLEMENTATION NOTES While the traditional mac(9) entry points are implemented, policy labels are not used; instead, access control decisions are made by iterating through the internal list of rules until a rule which denies the particu- lar access is found, or the end of the list is reached.
