* tun/tap: merge and rename to `tuntap`Kyle Evans2019-05-081-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tun(4) and tap(4) share the same general management interface and have a lot in common. Bugs exist in tap(4) that have been fixed in tun(4), and vice-versa. Let's reduce the maintenance requirements by merging them together and using flags to differentiate between the three interface types (tun, tap, vmnet). This fixes a couple of tap(4)/vmnet(4) issues right out of the gate: - tap devices may no longer be destroyed while they're open [0] - VIMAGE issues already addressed in tun by kp [0] emaste had removed an easy-panic-button in r240938 due to devdrn blocking. A naive glance over this leads me to believe that this isn't quite complete -- destroy_devl will only block while executing d_* functions, but doesn't block the device from being destroyed while a process has it open. The latter is the intent of the condvar in tun, so this is "fixed" (for certain definitions of the word -- it wasn't really broken in tap, it just wasn't quite ideal). ifconfig(8) also grew the ability to map an interface name to a kld, so that `ifconfig {tun,tap}0` can continue to autoload the correct module, and `ifconfig vmnet0 create` will now autoload the correct module. This is a low overhead addition. (MFC commentary) This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this, and how critical they are. Changes after this are likely easily MFC'd without taking this merge, but the merge will be easier. I have no plans to do this MFC as of now.

* Remove AppleTalk support.Gleb Smirnoff2014-03-141-4/+1
| | | | | | | | | | | | | 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
* Remove IPX support.Gleb Smirnoff2014-03-141-4/+1
| | | | | | | | | | | | | | IPX was a network transport protocol in Novell's NetWare network operating system from late 80s and then 90s. The NetWare itself switched to TCP/IP as default transport in 1998. Later, in this century the Novell Open Enterprise Server became successor of Novell NetWare. The last release that claimed to still support IPX was OES 2 in 2007. Routing equipment vendors (e.g. Cisco) discontinued support for IPX in 2011. Thus, IPX won't be supported in FreeBSD 11.0-RELEASE. Notes: svn path=/head/; revision=263140

Thus, such fake files won't be created at all if modules are built with the kernel. Some modules undergo cleanup like removing unused or unneeded options or .h files, without which they wouldn't build this way or the other.

* Avoid the modules madness I inadvertently introduced by making thePoul-Henning Kamp2000-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | cloning infrastructure standard in kern_conf. Modules are now the same with or without devfs support. If you need to detect if devfs is present, in modules or elsewhere, check the integer variable "devfs_present". This happily removes an ugly hack from kern/vfs_conf.c. This forces a rename of the eventhandler and the standard clone helper function. Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include like <sys/queue.h> Remove all #includes of opt_devfs.h they no longer matter. Notes: svn path=/head/; revision=65374

| | | | | | | | | | This means that the kernel can be totally self contained now and is not dependent on the last buildworld to update /usr/share/mk.
