====================
tipc: add some patches
This series adds patches to fix some issues in TIPC streaming & service
subscription.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When a service subscription is expired or canceled by user, it needs to
be deleted from the subscription list, so that new subscriptions can be
registered (max = 65535 per net). However, there are two issues in code
that can cause such an unused subscription to persist:
1) The 'tipc_conn_delete_sub()' has a loop on the subscription list but
it makes a break shortly when the 1st subscription differs from the one
specified, so the subscription will not be deleted.
2) In case a subscription is canceled, the code to remove the
'TIPC_SUB_CANCEL' flag from the subscription filter does not work if it
is a local subscription (i.e. the little endian isn't involved). So, it
will be no matches when looking for the subscription to delete later.
The subscription(s) will be removed eventually when the user terminates
its topology connection but that could be a long time later. Meanwhile,
the number of available subscriptions may be exhausted.
This commit fixes the two issues above, so as needed a subscription can
be deleted correctly.

Upon receipt of a service subscription request from user via a topology
connection, one 'sub' object will be allocated in kernel, so it will be
able to send an event of the service if any to the user correspondingly
then. Also, in case of any failure, the connection will be shutdown and
all the pertaining 'sub' objects will be freed.
However, there is a race condition as follows resulting in memory leak:
receive-work connection send-work
| | |
sub-1 |<------//-------| |
sub-2 |<------//-------| |
| |<---------------| evt for sub-x
sub-3 |<------//-------| |
: : :
: : :
| /--------| |
| | * peer closed |
| | | |
| | |<-------X-------| evt for sub-y
| | |<===============|
sub-n |<------/ X shutdown |
-> orphan | |
That is, the 'receive-work' may get the last subscription request while
the 'send-work' is shutting down the connection due to peer close.
We had a 'lock' on the connection, so the two actions cannot be carried
out simultaneously. If the last subscription is allocated e.g. 'sub-n',
before the 'send-work' closes the connection, there will be no issue at
all, the 'sub' objects will be freed. In contrast the last subscription
will become orphan since the connection was closed, and we released all
references.
This commit fixes the issue by simply adding one test if the connection
remains in 'connected' state right after we obtain the connection lock,
then a subscription object can be created as usual, otherwise we ignore
it.

Currently when a connection is in Nagle mode, we set the 'ack_required'
bit in the last sending buffer and wait for the corresponding ACK prior
to pushing more data. However, on the receiving side, the ACK is issued
only when application really reads the whole data. Even if part of the
last buffer is received, we will not do the ACK as required. This might
cause an unnecessary delay since the receiver does not always fetch the
message as fast as the sender, resulting in a large latency in the user
message sending, which is: [one RTT + the receiver processing time].
The commit makes Nagle ACK as soon as possible i.e. when a message with
the 'ack_required' arrives in the receiving side's stack even before it
is processed or put in the socket receive queue...
This way, we can limit the streaming latency to one RTT as committed in
Nagle mode.

When we changed the file registration handling, it became important to
iterate the bulk request freeing list for fixed files as well, or we
miss dropping the fixed file reference. If not, we're leaking references,
and we'll get a kworker stuck waiting for file references to disappear.
This also means we can remove the special casing of fixed vs non-fixed
files, we need to iterate for both and we can just rely on
__io_req_aux_free() doing io_put_file() instead of doing it manually.

Though rdpkru and wrpkru are contingent upon CR4.PKE, the PKRU
resource isn't. It can be read with XSAVE and written with XRSTOR.
So, if we don't set the guest PKRU value here(kvm_load_guest_xsave_state),
the guest can read the host value.
In case of kvm_load_host_xsave_state, guest with CR4.PKE clear could
potentially use XRSTOR to change the host PKRU value.
While at it, move pkru state save/restore to common code and the
host_pkru field to kvm_vcpu_arch. This will let SVM support protection keys.
