[ Upstream commit c7cd82b90599fa10915f41e3dd9098a77d0aa7b6 ]
Currently vosck_connect() increments sock refcount for nonblocking
socket each time it's called, which can lead to memory leak if
it's called multiple times because connect timeout function decrements
sock refcount only once.
Fixes it by making vsock_connect() return -EALREADY immediately when
sock state is already SS_CONNECTING.
Fixes: d021c344051a ("VSOCK: Introduce VM Sockets")

[ Upstream commit e16edc99d658cd41c60a44cc14d170697aa3271f ]
VMCI feature is not supported in conjunction with the vSphere Fault
Tolerance (FT) feature.
VMware Tools can repeatedly try to create a vsock connection. If FT is
enabled the kernel logs is flooded with the following messages:
qp_alloc_hypercall result = -20
Could not attach to queue pair with -20
"qp_alloc_hypercall result = -20" was hidden by commit e8266c4c3307
("VMCI: Stop log spew when qp allocation isn't possible"), but "Could
not attach to queue pair with -20" is still there flooding the log.
Since the error message can be useful in some cases, print it only once.

[ Upstream commit 1f935e8e72ec28dddb2dc0650b3b6626a293d94b ]
For AF_VSOCK, accept() currently returns sockets that are unlabelled.
Other socket families derive the child's SID from the SID of the parent
and the SID of the incoming packet. This is typically done as the
connected socket is placed in the queue that accept() removes from.
Reuse the existing 'security_sk_clone' hook to copy the SID from the
parent (server) socket to the child. There is no packet SID in this
case.

When the android virtual device stays up for long periods of time, the
SLAB sustains everincreasing fragmentation. Contributing to this
fragmentation are the virtio packet buffer allocations which are a
drain on 64Kb compound pages. Eventually these can't be allocated due to
fragmentation.
To enable successful allocations for this packet buffer, the packet
buffer's size needs to be reduced.
To enable a reduction without impacting other partners, this var is
being exposed as a command line param.

commit 1c5fae9c9a092574398a17facc31c533791ef232 upstream.
In vsock_shutdown() we touched some socket fields without holding the
socket lock, such as 'state' and 'sk_flags'.
Also, after the introduction of multi-transport, we are accessing
'vsk->transport' in vsock_send_shutdown() without holding the lock
and this call can be made while the connection is in progress, so
the transport can change in the meantime.
To avoid issues, we hold the socket lock when we enter in
vsock_shutdown() and release it when we leave.
Among the transports that implement the 'shutdown' callback, only
hyperv_transport acquired the lock. Since the caller now holds it,
we no longer take it.

[ Upstream commit af545bb5ee53f5261db631db2ac4cde54038bdaf ]
During __vsock_create() CAP_NET_ADMIN is used to determine if the
vsock_sock->trusted should be set to true. This value is used later
for determing if a remote connection should be allowed to connect
to a restricted VM. Unfortunately, if the caller doesn't have
CAP_NET_ADMIN, an audit message such as an selinux denial is
generated even if the caller does not want a trusted socket.
Logging errors on success is confusing. To avoid this, switch the
capable(CAP_NET_ADMIN) check to the noaudit version.

[ Upstream commit 7e0afbdfd13d1e708fe96e31c46c4897101a6a43 ]
The accept(2) is an "input" socket interface, so we should use
SO_RCVTIMEO instead of SO_SNDTIMEO to set the timeout.
So this patch replace sock_sndtimeo() with sock_rcvtimeo() to
use the right timeout in the vsock_accept().

[ Upstream commit 8236b08cf50f85bbfaf48910a0b3ee68318b7c4b ]
The old code always starts from fixed port for VMADDR_PORT_ANY. Sometimes
when VMM crashed, there is still orphaned vsock which is waiting for
close timer, then it could cause connection time out for new started VM
if they are trying to connect to same port with same guest cid since the
new packets could hit that orphaned vsock. We could also fix this by doing
more in vhost_vsock_reset_orphans, but any way, it should be better to start
from a random local port instead of a fixed one.

As reported by Michal, vsock_stream_sendmsg() could still
sleep at vsock_stream_has_space() after prepare_to_wait():
vsock_stream_has_space
vmci_transport_stream_has_space
vmci_qpair_produce_free_space
qp_lock

mutex_lock
Just switch to the new wait API like we did for commit

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.

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.

There are several places where the listener and pending or accept queue
child sockets are accessed at the same time. Lockdep is unhappy that
two locks from the same class are held.
Tell lockdep that it is safe and document the lock ordering.
Originally Claudio Imbrenda <imbrenda@linux.vnet.ibm.com> sent a similar
patch asking whether this is safe. I have audited the code and also
covered the vsock_pending_work() function.

[ Upstream commit a915b982d8f5e4295f64b8dd37ce753874867e88 ]
If a server side socket is bound to an address, but not in the listening
state yet, incoming connection requests should receive a reset control
packet in response. However, the function used to send the reset
silently drops the reset packet if the sending socket isn't bound
to a remote address (as is the case for a bound socket not yet in
the listening state). This change fixes this by using the src
of the incoming packet as destination for the reset packet in
this case.

[ 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.

commit 8ab18d71de8b07d2c4d6f984b718418c09ea45c5 upstream.
The check in vmci_transport_peer_detach_cb should only allow a
detach when the qp handle of the transport matches the one in
the detach message.
Testing: Before this change, a detach from a peer on a different
socket would cause an active stream socket to register a detach.

[ Upstream commit dedc58e067d8c379a15a8a183c5db318201295bb ]
The peer may be expecting a reply having sent a request and then done a
shutdown(SHUT_WR), so tearing down the whole socket at this point seems
wrong and breaks for me with a client which does a SHUT_WR.
Looking at other socket family's stream_recvmsg callbacks doing a shutdown
here does not seem to be the norm and removing it does not seem to have
had any adverse effects that I can see.
I'm using Stefan's RFC virtio transport patches, I'm unsure of the impact
on the vmci transport.

When a listen socket enqueues a connection for userspace to accept(),
the sk->sk_data_ready() callback should be invoked. In-kernel socket
users rely on this callback to detect when incoming connections are
available.
Currently the sk->sk_state_change() callback is invoked by
vmci_transport.c. This happens to work for userspace applications since
sk->sk_state_change = sock_def_wakeup() and sk->sk_data_ready =
sock_def_readable() both wake up the accept() waiter. In-kernel socket
users, on the other hand, fail to detect incoming connections.

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/.

The recent fix for the vsock sock_put issue used the wrong
initializer for the transport spin_lock causing an issue when
running with lockdep checking.
Testing: Verified fix on kernel with lockdep enabled.

In the vsock vmci_transport driver, sock_put wasn't safe to call
in interrupt context, since that may call the vsock destructor
which in turn calls several functions that should only be called
from process context. This change defers the callling of these
functions to a worker thread. All these functions were
deallocation of resources related to the transport itself.
Furthermore, an unused callback was removed to simplify the
cleanup.
Multiple customers have been hitting this issue when using
VMware tools on vSphere 2015.
Also added a version to the vmci transport module (starting from
1.0.2.0-k since up until now it appears that this module was
sharing version with vsock that is currently at 1.0.1.0-k).

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.

Note that the code _using_ ->msg_iter at that point will be very
unhappy with anything other than unshifted iovec-backed iov_iter.
We still need to convert users to proper primitives.

This encapsulates all of the skb_copy_datagram_iovec() callers
with call argument signature "skb, offset, msghdr->msg_iov, length".
When we move to iov_iters in the networking, the iov_iter object will
sit in the msghdr.
Having a helper like this means there will be less places to touch
during that transformation.
Based upon descriptions and patch from Al Viro.

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...
