ATM: use designated initializers

2016-12-17T16:56:57+00:00

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.

vsock/virtio: fix src/dst cid format

2016-12-15T04:59:19+00:00

These fields are 64 bit, using le32_to_cpu and friends
on these will not do the right thing.
Fix this up.

vsock/virtio: add a missing __le annotation

2016-12-15T04:59:18+00:00

guest cid is read from config space, therefore it's in little endian
format and is treated as such, annotate it accordingly.

VSOCK: add loopback to virtio_transport

2016-11-24T16:53:15+00:00

The VMware VMCI transport supports loopback inside virtual machines.
This patch implements loopback for virtio-vsock.

Flow control is handled by the virtio-vsock protocol as usual.  The
sending process stops transmitting on a connection when the peer's
receive buffer space is exhausted.

Cathy Avery  noticed this difference between VMCI and
virtio-vsock when a test case using loopback failed.  Although loopback
isn't the main point of AF_VSOCK, it is useful for testing and
virtio-vsock must match VMCI semantics so that userspace programs run
regardless of the underlying transport.

My understanding is that loopback is not supported on the host side with
VMCI.  Follow that by implementing it only in the guest driver, not the
vhost host driver.

net: fix sleeping for sk_wait_event()

2016-11-14T18:17:21+00:00

Similar to commit 14135f30e33c ("inet: fix sleeping inside inet_wait_for_connect()"),
sk_wait_event() needs to fix too, because release_sock() is blocking,
it changes the process state back to running after sleep, which breaks
the previous prepare_to_wait().

Switch to the new wait API.

VSOCK: Don't dec ack backlog twice for rejected connections

2016-09-27T11:59:25+00:00

If a pending socket is marked as rejected, we will decrease the
sk_ack_backlog twice. So don't decrement it for rejected sockets
in vsock_pending_work().

Testing of the rejected socket path was done through code
modifications.

vhost/vsock: drop space available check for TX vq

2016-08-15T02:05:21+00:00

Remove unnecessary use of enable/disable callback notifications
and the incorrect more space available check.

The virtio_transport_tx_work handles when the TX virtqueue
has more buffers available.
