Release 4.11 net/decnet/af_decnet.c
/*
* DECnet An implementation of the DECnet protocol suite for the LINUX
* operating system. DECnet is implemented using the BSD Socket
* interface as the means of communication with the user level.
*
* DECnet Socket Layer Interface
*
* Authors: Eduardo Marcelo Serrat <emserrat@geocities.com>
* Patrick Caulfield <patrick@pandh.demon.co.uk>
*
* Changes:
* Steve Whitehouse: Copied from Eduardo Serrat and Patrick Caulfield's
* version of the code. Original copyright preserved
* below.
* Steve Whitehouse: Some bug fixes, cleaning up some code to make it
* compatible with my routing layer.
* Steve Whitehouse: Merging changes from Eduardo Serrat and Patrick
* Caulfield.
* Steve Whitehouse: Further bug fixes, checking module code still works
* with new routing layer.
* Steve Whitehouse: Additional set/get_sockopt() calls.
* Steve Whitehouse: Fixed TIOCINQ ioctl to be same as Eduardo's new
* code.
* Steve Whitehouse: recvmsg() changed to try and behave in a POSIX like
* way. Didn't manage it entirely, but its better.
* Steve Whitehouse: ditto for sendmsg().
* Steve Whitehouse: A selection of bug fixes to various things.
* Steve Whitehouse: Added TIOCOUTQ ioctl.
* Steve Whitehouse: Fixes to username2sockaddr & sockaddr2username.
* Steve Whitehouse: Fixes to connect() error returns.
* Patrick Caulfield: Fixes to delayed acceptance logic.
* David S. Miller: New socket locking
* Steve Whitehouse: Socket list hashing/locking
* Arnaldo C. Melo: use capable, not suser
* Steve Whitehouse: Removed unused code. Fix to use sk->allocation
* when required.
* Patrick Caulfield: /proc/net/decnet now has object name/number
* Steve Whitehouse: Fixed local port allocation, hashed sk list
* Matthew Wilcox: Fixes for dn_ioctl()
* Steve Whitehouse: New connect/accept logic to allow timeouts and
* prepare for sendpage etc.
