net: Unbreak compat_sys_{send,recv}msg

2013-06-06T18:52:14Z

I broke them in this commit: commit 1be374a0518a288147c6a7398792583200a67261 Author: Andy Lutomirski Date: Wed May 22 14:07:44 2013 -0700 net: Block MSG_CMSG_COMPAT in send(m)msg and recv(m)msg This patch adds __sys_sendmsg and __sys_sendmsg as common helpers that accept MSG_CMSG_COMPAT and blocks MSG_CMSG_COMPAT at the syscall entrypoints. It also reverts some unnecessary checks in sys_socketcall. Apparently I was suffering from underscore blindness the first time around.

Hoist memcpy_fromiovec/memcpy_toiovec into lib/

2013-05-20T00:54:22Z

ERROR: "memcpy_fromiovec" [drivers/vhost/vhost_scsi.ko] undefined! That function is only present with CONFIG_NET. Turns out that crypto/algif_skcipher.c also uses that outside net, but it actually needs sockets anyway. In addition, commit 6d4f0139d642c45411a47879325891ce2a7c164a added CONFIG_NET dependency to CONFIG_VMCI for memcpy_toiovec, so hoist that function and revert that commit too. socket.h already includes uio.h, so no callers need updating; trying only broke things fo x86_64 randconfig (thanks Fengguang!).

NFC: llcp: Implement socket options

2013-03-10T21:20:05Z

Some LLCP services (e.g. the validation ones) require some control over the LLCP link parameters like the receive window (RW) or the MIU extension (MIUX). This can only be done through socket options. Signed-off-by: Samuel Ortiz

VSOCK: Introduce VM Sockets

2013-02-11T00:41:08Z

VM Sockets allows communication between virtual machines and the hypervisor. User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/ Signed-off-by: George Zhang Signed-off-by: Dmitry Torokhov Signed-off-by: Andy king Signed-off-by: David S.

net-tcp: Fast Open client - sendmsg(MSG_FASTOPEN)

2012-07-19T18:02:03Z

sendmsg() (or sendto()) with MSG_FASTOPEN is a combo of connect(2) and write(2). The application should replace connect() with it to send data in the opening SYN packet. For blocking socket, sendmsg() blocks until all the data are buffered locally and the handshake is completed like connect() call. It returns similar errno like connect() if the TCP handshake fails. For non-blocking socket, it returns the number of bytes queued (and transmitted in the SYN-data packet) if cookie is available. If cookie is not available, it transmits a data-less SYN packet with Fast Open cookie request option and returns -EINPROGRESS like connect(). Using MSG_FASTOPEN on connecting or connected socket will result in simlar errno like repeating connect() calls. Therefore the application should only use this flag on new sockets. The buffer size of sendmsg() is independent of the MSS of the connection. Signed-off-by: Yuchung Cheng Acked-by: Eric Dumazet Signed-off-by: David S. Miller

tcp: tcp_sendpages() should call tcp_push() once

2012-04-05T23:04:27Z

commit 2f533844242 (tcp: allow splice() to build full TSO packets) added a regression for splice() calls using SPLICE_F_MORE. We need to call tcp_flush() at the end of the last page processed in tcp_sendpages(), or else transmits can be deferred and future sends stall. Add a new internal flag, MSG_SENDPAGE_NOTLAST, acting like MSG_MORE, but with different semantic. For all sendpage() providers, its a transparent change. Only sock_sendpage() and tcp_sendpages() can differentiate the two different flags provided by pipe_to_sendpage() Reported-by: Tom Herbert Cc: Nandita Dukkipati Cc: Neal Cardwell Cc: Tom Herbert Cc: Yuchung Cheng Cc: H.K.
