This patch adds OOB support for AF_UNIX sockets. The semantics is same as TCP. The last byte of a message with the OOB flag is treated as the OOB byte. The byte is separated into a skb and a pointer to the skb is stored in unix_sock. The pointer is used to enforce OOB semantics.

If you say Y here, you will include support for Unix domain sockets;
|
|
sockets are the standard Unix mechanism for establishing and
|
|
accessing network connections. Many commonly used programs such as
|
|
the X Window system and syslog use these sockets even if your
|
|
machine is not connected to any network. Unless you are working on
|
|
an embedded system or something similar, you therefore definitely
|
|
want to say Y here.
|
|
|
|
To compile this driver as a module, choose M here: the module will be
|
|
called unix. Note that several important services won't work
|
|
correctly if you say M here and then neglect to load the module.
|
|
|
|
Say Y unless you know what you are doing.

If unsure, say Y.
