vmxnet3 has a function vmxnet3_parse_and_copy_hdr which, among other operations,

pulls the skb (both of which can be done without holding the spinlock with irqs

and

vmxnet3_copy_header, which just copies the skb to the tx ring under the lock

drm/i915: Fix bogus dig_port_map[] assignment for pre-HSW

The recent commit [0bdf5a05647a: drm/i915: Add reverse mapping between
port and intel_encoder] introduced a reverse mapping to retrieve
intel_dig_port object from the port number.  The code assumed that the
port vs intel_dig_port are 1:1 mapping.  But in reality, this was a
too naive assumption.

As Martin reported about the missing HDMI audio on his SNB machine,
pre-HSW chips may have multiple intel_dig_port objects corresponding
to the same port.  Since we assign the mapping statically at the init
time and the multiple objects override the map, it may not match with
the actually enabled output.

This patch tries to address the regression above.  The reverse mapping
is provided basically only for the audio callbacks, so now we set /
clear the mapping dynamically at enabling and disabling HDMI/DP audio,
so that we can always track the latest and correct object
corresponding to the given port.

mlxsw: pci: Correctly determine if descriptor queue is full

The descriptor queues for sending (SDQs) and receiving (RDQs) packets
are managed by two counters - producer and consumer - which are both
16-bit in size. A queue is considered full when the difference between
the two equals the queue's maximum number of descriptors.

However, if the producer counter overflows, then it's possible for the
full queue check to fail, as it doesn't take the overflow into account.
In such a case, descriptors already passed to the device - but for which
a completion has yet to be posted - will be overwritten, thereby causing
undefined behavior. The above can be achieved under heavy load (~30

ASoC: Fixes for v4.5

This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places.  They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.

The other changes are:
 - A fix for Qualcomm devices to work on big endian systems.  The
   original change is actually correct but triggered a bug in regmap
   which is too invasive to fix for this cycle and can be worked around
   by just letting regmap pick the default.
 - A fix for the Samsung I2S driver locking which wasn't using IRQ safe
   spinlocks when it needed to.
 - A fix for the new Intel Sky Lake driver forgetting that C pointer
   arithmetic takes the type of the pointer into consideration.
 - A revert of a change to the FSL SSI driver that broke some systems.
 - A fix for the cleanup path of the wm9713 driver.
 - A fix for some incorrect register definitions in the ADAU17x1 driver
   that caused misclocking in some configurations.
 - A fix for the tracepoints for jack detection to avoid using an
   internal field of the core jack structure which is no longer present
   in all configurations.
 - A fix for another of the new Intel drivers which tried to write to a
   string literal.

ipvs: correct initial offset of Call-ID header search in SIP persistence engine

The IPVS SIP persistence engine is not able to parse the SIP header
"Call-ID" when such header is inserted in the first positions of
the SIP message.

When IPVS is configured with "--pe sip" option, like for example:
ipvsadm -A -u 1.2.3.4:5060 -s rr --pe sip -p 120 -o
some particular messages (see below for details) do not create entries
in the connection template table, which can be listed with:
ipvsadm -Lcn --persistent-conn

Problematic SIP messages are SIP responses having "Call-ID" header
positioned just after message first line:
SIP/2.0 200 OK
[Call-ID header here]
[rest of the headers]

When "Call-ID" header is positioned down (after a few other headers)
it is correctly recognized.

This is due to the data offset used in get_callid function call inside
ip_vs_pe_sip.c file: since dptr already points to the start of the
SIP message, the value of dataoff should be initially 0.
Otherwise the header is searched starting from some bytes after the
first character of the SIP message.

Julian Anastasov [Sat, 5 Mar 2016 13:03:22 +0000 (15:03 +0200)]
ipvs: drop first packet to redirect conntrack

Jiri Bohac is reporting for a problem where the attempt
to reschedule existing connection to another real server
needs proper redirect for the conntrack used by the IPVS
connection. For example, when IPVS connection is created
to NAT-ed real server we alter the reply direction of
conntrack. If we later decide to select different real
server we can not alter again the conntrack. And if we
expire the old connection, the new connection is left
without conntrack.

So, the only way to redirect both the IPVS connection and
the Netfilter's conntrack is to drop the SYN packet that
hits existing connection, to wait for the next jiffie
to expire the old connection and its conntrack and to rely
on client's retransmission to create new connection as
usually.

Jiri Bohac provided a fix that drops all SYNs on rescheduling,
I extended his patch to do such drops only for connections
that use conntrack. Here is the original report from Jiri Bohac:

Since commit dc7b3eb900aa ("ipvs: Fix reuse connection if real server
is dead"), new connections to dead servers are redistributed
immediately to new servers.  The old connection is expired using
ip_vs_conn_expire_now() which sets the connection timer to expire
immediately.

However, before the timer callback, ip_vs_conn_expire(), is run
to clean the connection's conntrack entry, the new redistributed
connection may already be established and its conntrack removed
instead.

Fix this by dropping the first packet of the new connection
instead, like we do when the destination server is not available.
The timer will have deleted the old conntrack entry long before
the first packet of the new connection is retransmitted.
