the following command currently fails:

 The following test case IDs are not unique:

 Please correct them before continuing.

this happens because there are two tests having the same id:

The reason is that cpdma_chan_submit_si() now stores original buffer length
(sw_len) in CPDMA descriptor instead of adjusted buffer length (hw_len)
used to map the buffer.

Hence, fix an issue by passing correct buffer length in CPDMA descriptor.

The issue was caused by transport->ipaddr set with uninit addr param, which
was passed by:

  sctp_transport_init net/sctp/transport.c:47 [inline]

  sctp_process_param net/sctp/sm_make_chunk.c:2524 [inline]

where 'addr' is set by sctp_v4_from_addr_param(), and it doesn't initialize
the padding of addr->v4.

Later when calling sctp_make_heartbeat(), hbinfo.daddr(=transport->ipaddr)
will become the part of skb, and the issue occurs.

This patch is to fix it by initializing the padding of addr->v4 in
sctp_v4_from_addr_param(), as well as other functions that do the similar
thing, and these functions shouldn't trust that the caller initializes the
memory, as Marcelo suggested.

1) syzbot reported an uninit-value in bond_neigh_setup() [1]

 bond_neigh_setup() uses a temporary on-stack 'struct neigh_parms parms',
 but only clears parms.neigh_setup field.

 A stacked bonding device would then enter bond_neigh_setup()
 and read garbage from parms->dev.

 If we get really unlucky and garbage is matching @dev, then we
 could recurse and eventually crash.

 Let's make sure the whole structure is cleared to avoid surprises.

2) bond_neigh_setup() can be called while another cpu manipulates
 the master device, removing or adding a slave.
 We need at least rcu protection to prevent use-after-free.

Note: Prior code does not support a stack of bonding devices,
      this patch does not attempt to fix this, and leave a comment instead.

neigh_cleanup() has not been used for seven years, and was a wrong design.

Messing with shared pointer in bond_neigh_init() without proper

Marc Kleine-Budde says:

====================
pull-request: can 2019-12-08

this is a pull request of 13 patches for net/master.

The first two patches are by Dan Murphy. He adds himself as a maintainer to the
m-can MMIO and tcan SPI driver.

The next two patches the j1939 stack. The first one is by Oleksij Rempel and
fixes a locking problem found by the syzbot, the second one is by me an fixes a
mistake in the documentation.

Srinivas Neeli fixes missing RX CAN packets on CANFD2.0 in the xilinx driver.

Sean Nyekjaer fixes a possible deadlock in the the flexcan driver after
suspend/resume. Joakim Zhang contributes two patches for the flexcan driver
that fix problems with the low power enter/exit.

The next 4 patches all target the tcan part of the m_can driver. Sean Nyekjaer
adds the required delay after reset and fixes the device tree binding example.
Dan Murphy's patches make the wake-gpio optional.

In the last patch Xiaolong Huang fixes several kernel memory info leaks to the
USB device in the kvaser_usb_leaf driver.

The existing rbtree implementation might store consecutive elements
where the closing element and the opening element might overlap, eg.

	[ a, a+1) [ a+1, a+2)

This patch removes the optimization for non-anonymous sets in the exact
matching case, where it is assumed to stop searching in case that the
closing element is found. Instead, invalidate candidate interval and
keep looking further in the tree.

The lookup/get operation might return false, while there is an element
in the rbtree. Moreover, the get operation returns true as if a+2 would
be in the tree. This happens with named sets after several set updates.

The existing lookup optimization (that only works for the anonymous
sets) might not reach the opening [ a+1,... element if the closing
...,a+1) is found in first place when walking over the rbtree. Hence,
walking the full tree in that case is needed.

This patch fixes the lookup and get operations.

Stop Mode is entered when Stop Mode is requested at chip level and
MCR[LPM_ACK] is asserted by the FlexCAN.

Double check with IP owner, the MCR[LPM_ACK] bit should be polled for
stop mode acknowledgment, not the acknowledgment from chip level which
is used to gate flexcan clocks.

The MCR[LPMACK] read-only bit indicates that FlexCAN is in a lower-power
mode (Disabled mode, Doze mode, Stop mode).

The CPU can poll this bit to know when FlexCAN has actually entered low
power mode. The low power enter/exit acknowledgment helper will reduce
code duplication for disabled mode, doze mode and stop mode.

When suspending, and there is still CAN traffic on the interfaces the
flexcan immediately wakes the platform again. As it should :-). But it
throws this error msg:

[ 3169.378661] PM: noirq suspend of devices failed

On the way down to suspend the interface that throws the error message
calls flexcan_suspend() but fails to call flexcan_noirq_suspend(). That
means flexcan_enter_stop_mode() is called, but on the way out of suspend
the driver only calls flexcan_resume() and skips flexcan_noirq_resume(),
thus it doesn't call flexcan_exit_stop_mode(). This leaves the flexcan
in stop mode, and with the current driver it can't recover from this
even with a soft reboot, it requires a hard reboot.

This patch fixes the deadlock when using self wakeup, by calling
flexcan_exit_stop_mode() from flexcan_resume() instead of
flexcan_noirq_resume().

This also fixes another issue: CAN frames are received out-of-order in
first IRQ handler run after wakeup.

The problem is that the wakeup latency from frame reception to the IRQ
handler (where the CAN frames are sorted by timestamp) is much bigger
than the time stamp counter wrap around time. This means it's
impossible to sort the CAN frames by timestamp.

The reason is that the controller exits stop mode during noirq resume,
which means it receives frames immediately, but interrupt handling is
still not possible.

So exit stop mode during resume stage instead of noirq resume fixes this
issue.

This issues was caused by null pointer deference. Where j1939_sk_bind()
was using currently not existing priv.

Possible scenario may look as following:
cpu0                                    cpu1
bind()
                                        bind()
 j1939_sk_bind()
                                         j1939_sk_bind()
  priv = jsk->priv;
                                         priv = jsk->priv;
  lock_sock(sock->sk);
  priv = j1939_netdev_start(ndev);
  j1939_jsk_add(priv, jsk);
    jsk->priv = priv;
  relase_sock(sock->sk);
                                         lock_sock(sock->sk);
                                         j1939_jsk_del(priv, jsk);
                                         ..... ooops ......

With this patch we move "priv = jsk->priv;" after the lock, to avoid
assigning of wrong priv pointer.
