21041af8a7 This commit modifies the Unix domain local socket design. Local sockets are built on top of pipes. The Local socket implementation maintained file descriptors to interrupt with the pipes. File descriptors have the bad property that they are valid only while running on the thread within the task that created the local socket. 
As a policy, all internal OS implementations must use "detached" files which are valid in any context and do not depend on the validity of a file descriptor at any point in time.  This commit converts the usage of file descriptors to detached files throughout the local socket implementation.

Squashed commit of the following:

    net/local: Finish change to eliminate use of file descriptors.
    net/local:  A little more of the conversion.
    net/local: Beginning of chnages to eliminate use of file descriptors in the local socket implementeation. poll() will be a problem.

1b9cb70828 Sockets: Initial steps to adde a socket interface to the networking. Each address family will have an interface that describes how to perform socket operations on that address family. Currently only a couple of methods are defined in the table as a proof of concept. More to come. Currently there are only tables for the INET/INET6 family, the Unix LOCAL family, and the raw PACKET family. Hopefully there will be AF_IEEE802154 and AF_BLUETOOTH comming down the pike. 2017-07-12 15:07:32 -06:00

0f5c35260b Local sockets: Local stream sockets had problem of double releasing pipes (both server and client attempt release), which causes wrong pipe pair being closed in multi-client case. Solve by adding per connection instance ID to pipe names. From Jussi Kivilinna (2015-05-12). 2015-05-12 07:47:32 -06:00
