vsock: split dwork to avoid reinitializations

2018-08-22T05:47:13Z

[ Upstream commit 455f05ecd2b219e9a216050796d30c830d9bc393 ] syzbot reported that we reinitialize an active delayed work in vsock_stream_connect(): ODEBUG: init active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x90 kernel/workqueue.c:1414 WARNING: CPU: 1 PID: 11518 at lib/debugobjects.c:329 debug_print_object+0x16a/0x210 lib/debugobjects.c:326 The pattern is apparently wrong, we should only initialize the dealyed work once and could repeatly schedule it. So we have to move out the initializations to allocation side. And to avoid confusion, we can split the shared dwork into two, instead of re-using the same one.

VSOCK: defer sock removal to transports

2016-08-01T23:57:28Z

The virtio transport will implement graceful shutdown and the related SO_LINGER socket option. This requires orphaning the sock but keeping it in the table of connections after .release(). This patch adds the vsock_remove_sock() function and leaves it up to the transport when to remove the sock. Signed-off-by: Stefan Hajnoczi Signed-off-by: Michael S. Tsirkin

VSOCK: transport-specific vsock_transport functions

2016-08-01T23:57:28Z

struct vsock_transport contains function pointers called by AF_VSOCK core code. The transport may want its own transport-specific function pointers and they can be added after struct vsock_transport. Allow the transport to fetch vsock_transport. It can downcast it to access transport-specific function pointers. The virtio transport will use this.

VSOCK: define VSOCK_SS_LISTEN once only

2015-11-01T17:14:47Z

The SS_LISTEN socket state is defined by both af_vsock.c and vmci_transport.c. This is risky since the value could be changed in one file and the other would be out of sync. Rename from SS_LISTEN to VSOCK_SS_LISTEN since the constant is not part of enum socket_state (SS_CONNECTED, ...). This way it is clear that the constant is vsock-specific. The big text reflow in af_vsock.c was necessary to keep to the maximum line length. Text is unchanged except for s/SS_LISTEN/VSOCK_SS_LISTEN/. Signed-off-by: Stefan Hajnoczi Signed-off-by: David S.

net: Pass kern from net_proto_family.create to sk_alloc

In preparation for changing how struct net is refcounted on kernel sockets pass the knowledge that we are creating a kernel socket from sock_create_kern through to sk_alloc. Signed-off-by: "Eric W. Biederman" Signed-off-by: David S. Miller

net: Remove iocb argument from sendmsg and recvmsg

2015-03-02T18:06:31Z

After TIPC doesn't depend on iocb argument in its internal implementations of sendmsg() and recvmsg() hooks defined in proto structure, no any user is using iocb argument in them at all now. Then we can drop the redundant iocb argument completely from kinds of implementations of both sendmsg() and recvmsg() in the entire networking stack.

vsock: Make transport the proto owner

2014-05-05T17:13:50Z

Right now the core vsock module is the owner of the proto family. This means there's nothing preventing the transport module from unloading if there are open sockets, which results in a panic. Fix that by allowing the transport to be the owner, which will refcount it properly. Includes version bump to 1.0.1.0-k Passes checkpatch this time, I swear...
