* Remove AppleTalk support.Gleb Smirnoff2014-03-141-881/+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

* Break at_ifawithnet() into two variants:Robert Watson2009-06-241-81/+117
| | | | | | | | | | | | | | | | | | - at_ifawithnet(), which acquires an locks it needs and returns an at_ifaddr reference. - at_ifawithnet_locked(), which relies on the caller locking at_ifaddr_list, and returns a pointer rather than a reference. Update various consumers to prefer one or the other, including ether and fddi output, to properly release at_ifaddr references.

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.

| | | | | | | | | | | | | | | | | - Unify reference count and lock initialization in a single function, ifa_init(). - Move tear-down from a macro (IFAFREE) to a function ifa_free(). - Move reference count bump from a macro (IFAREF) to a function ifa_ref(). - Instead of using a u_int protected by a mutex to refcount(9) for reference count management.

* Change the suser() API to take advantage of td_ucred as well as do aJohn Baldwin2002-04-011-1/+1
| | | | | | | | | | | | | | | general cleanup of the API. The entire API now consists of two functions similar to the pre-KSE API. The suser() function takes a thread pointer as its only argument. The td_ucred member of this thread must be valid so the only valid thread pointers are curthread and a few kernel threads such as thread0. The suser_cred() function takes a pointer to a struct ucred as its first argument and an integer flag as its second argument. The flag is currently only used for the PRISON_ROOT flag.

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change.

* Eradicate the variable "time" from the kernel, using various measures.Poul-Henning Kamp1998-03-301-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "time" wasn't a atomic variable, so splfoo() protection were needed around any access to it, unless you just wanted the seconds part. Most uses of time.tv_sec now uses the new variable time_second instead. gettime() changed to getmicrotime(0. Remove a couple of unneeded splfoo() protections, the new getmicrotime() is atomic, (until Bruce sets a breakpoint in it). A couple of places needed random data, so use read_random() instead of mucking about with time which isn't random. Add a new nfs_curusec() function. Mark a couple of bogosities involving the now disappeard time variable. Update ffs_update() to avoid the weird "== &time" checks, by fixing the one remaining call that passwd &time as args. Change profiling in ncr.c to use ticks instead of time. Resolution is the same. Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call hzto() which subtracts time" sequences.
