With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

This is support for the Novell networking protocol, IPX, commonly
|
|
used for local networks of Windows machines. You need it if you
|
|
want to access Novell NetWare file or print servers using the Linux
|
|
Novell client ncpfs (available from
|
|
<ftp://platan.vc.cvut.cz/pub/linux/ncpfs/>) or from
|
|
within the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO,
|
|
available from <http://www.tldp.org/docs.html#howto>). In order
|
|
to do the former, you'll also have to say Y to "NCP file system
|
|
support", below.
|
|
|
|
IPX is similar in scope to IP, while SPX, which runs on top of IPX,
|
|
is similar to TCP.
|
|
|
|
To turn your Linux box into a fully featured NetWare file server and
|
|
IPX router, say Y here and fetch either lwared from
|
|
<ftp://ibiblio.org/pub/Linux/system/network/daemons/> or
|
|
mars_nwe from <ftp://www.compu-art.de/mars_nwe/>. For more
|
|
information, read the IPX-HOWTO available from
|
|
<http://www.tldp.org/docs.html#howto>.
|
|
|
|
The IPX driver would enlarge your kernel by about 16 KB. To compile
|
|
this driver as a module, choose M here: the module will be called ipx.
|
|
Unless you want to integrate your Linux box with a local Novell
|
|
network, say N.

---help---
|
|
Every IPX network has an address that identifies it. Sometimes it is
|
|
useful to give an IPX "network" address to your Linux box as well
|
|
(for example if your box is acting as a file server for different
|
|
IPX networks: it will then be accessible from everywhere using the
|
|
same address). The way this is done is to create a virtual internal
|
|
"network" inside your box and to assign an IPX address to this
|
|
network. Say Y here if you want to do this; read the IPX-HOWTO at
|
|
<http://www.tldp.org/docs.html#howto> for details.
|
|
|
|
The full internal IPX network enables you to allocate sockets on
|
|
different virtual nodes of the internal network. This is done by
|
|
evaluating the field sipx_node of the socket address given to the
|
|
bind call. So applications should always initialize the node field
|
|
to 0 when binding a socket on the primary network. In this case the
|
|
socket is assigned the default node that has been given to the
|
|
kernel when the internal network was created. By enabling the full
|
|
internal IPX network the cross-forwarding of packets targeted at
|
|
'special' sockets to sockets listening on the primary network is
|
|
disabled. This might break existing applications, especially RIP/SAP
|
|
daemons. A RIP/SAP daemon that works well with the full internal net
|
|
can be found on <ftp://ftp.gwdg.de/pub/linux/misc/ncpfs/>.

|
|
If you don't know what you are doing, say N.
