* Remove AppleTalk support.Gleb Smirnoff2014-03-141-441/+0
| | | | | | | | | | | | | AppleTalk was a network transport protocol for Apple Macintosh devices in 80s and then 90s. Starting with Mac OS X in 2000 the AppleTalk was a legacy protocol and primary networking protocol is TCP/IP. The last Mac OS X release to support AppleTalk happened in 2009. The same year routing equipment vendors (namely Cisco) end their support. Thus, AppleTalk won't be supported in FreeBSD 11.0-RELEASE. Notes: svn path=/head/; revision=263152

* Add a global rwlock, at_ifaddr_rw, to protect the global netatalkRobert Watson2009-06-221-21/+25
| | | | | | | | | | | | | | | | address lists, at_ifaddr_list. Acquire the lock, and use ifaddr refcounts where necessary, to close most known address-related races in netatalk. Annotate one potential race in at_control() where we acquire an ifaddr reference, drop the global lock, and scrub the address from the ifnet before re-acquiring the global lock, which could allow for a writer-writer race.

* Move "options MAC" from opt_mac.h to opt_global.h, as it's now in GENERICRobert Watson2009-06-051-2/+0
| | | | | | | | | | | and used in a large number of files, but also because an increasing number of incorrect uses of MAC calls were sneaking in due to copy-and-paste of MAC-aware code without the associated opt_mac.h include. Discussed with: pjd Notes: svn path=/head/; revision=193511
* Add internal 'mac_policy_count' counter to the MAC Framework, which is aRobert Watson2009-06-021-5/+1
| | | | | | | | | | | | | | | | | | | | | count of the number of registered policies. Rather than unconditionally locking sockets before passing them into MAC, lock them in the MAC entry points only if mac_policy_count is non-zero. This avoids locking overhead for a number of socket system calls when no policies are registered, eliminating measurable overhead for the MAC Framework for the socket subsystem when there are no active policies. Possibly socket locks should be acquired by policies if they are required for socket labels, which would further avoid locking overhead when there are policies but they don't require labeling of sockets, or possibly don't even implement socket controls.

* Merge first in a series of TrustedBSD MAC Framework KPI changesRobert Watson2007-10-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | from Mac OS X Leopard--rationalize naming for entry points to the following general forms: mac_<object>_<method/action> mac_<object>_check_<method/action> The previous naming scheme was inconsistent and mostly reversed from the new scheme. Also, make object types more consistent and remove spaces from object types that contain multiple parts ("posix_sem" -> "posixsem") to make mechanical parsing easier. Introduce a new "netinet" object type for certain IPv4/IPv6-related methods. Also simplify, slightly, some entry point names. All MAC policy modules will need to be recompiled, and modules not updates as part of this commit will need to be modified to conform to the new KPI.

* Complete break-out of sys/sys/mac.h into sys/security/mac/mac_framework.hRobert Watson2006-10-221-1/+2
| | | | | | | | | | | | | | | | begun with a repo-copy of mac.h to mac_framework.h. sys/mac.h now contains the userspace and user<->kernel API and definitions, with all in-kernel interfaces moved to mac_framework.h, which is now included across most of the kernel instead. This change is the first step in a larger cleanup and sweep of MAC Framework interfaces in the kernel, and will not be MFC'd.
