If a VLAN tagged frame is received and the corresponding VLAN is not
configured on the soft interface, it will splat a WARN on every packet
received. This is a quite annoying behaviour for some scenarios, e.g. if
bat0 is bridged with eth0, and there are arbitrary VLAN tagged frames
from Ethernet coming in without having any VLAN configuration on bat0.
The code should probably create vlan objects on the fly and
transparently transport these VLAN-tagged Ethernet frames, but until
this is done, at least the WARN splat should be replaced by a rate
limited output.

If we have a system which uses fixed PHY devices and calls
fixed_phy_register() then fixed_phy_unregister() we can exhaust the
number of fixed PHYs available after a while, since we keep incrementing
the variable phy_fixed_addr, but we never decrement it.
This patch fixes that by converting the fixed PHY allocation to using
IDA, which takes care of the allocation/dealloaction of the PHY
addresses for us.

Diag intends to broadcast tcp_sk and udp_sk socket destruction.
Testing sk->sk_protocol for IPPROTO_TCP/IPPROTO_UDP alone is not
sufficient for this. Raw sockets can have the same type.
Add a test for sk->sk_type.

The proc connector messages include a sequence number, allowing userspace
programs to detect lost messages. However, performing this detection is
currently more difficult than necessary, since netlink messages can be
delivered to the application out-of-order. To fix this, leave pre-emption
disabled during cn_netlink_send(), and use GFP_NOWAIT.
The following was written as a test case. Building the kernel w/ make -j32
proved a reliable way to generate out-of-order cn_proc messages.
int
main(int argc, char *argv[])
{
static uint32_t last_seq[CPU_SETSIZE], seq;
int cpu, fd;
struct sockaddr_nl sa;
struct __attribute__((aligned(NLMSG_ALIGNTO))) {
struct nlmsghdr nl_hdr;
struct __attribute__((__packed__)) {
struct cn_msg cn_msg;
struct proc_event cn_proc;
};
} rmsg;
struct __attribute__((aligned(NLMSG_ALIGNTO))) {
struct nlmsghdr nl_hdr;
struct __attribute__((__packed__)) {
struct cn_msg cn_msg;
enum proc_cn_mcast_op cn_mcast;
};
} smsg;
fd = socket(PF_NETLINK, SOCK_DGRAM, NETLINK_CONNECTOR);
if (fd < 0) {
perror("socket");
}
sa.nl_family = AF_NETLINK;
sa.nl_groups = CN_IDX_PROC;
sa.nl_pid = getpid();
if (bind(fd, (struct sockaddr *)&sa, sizeof(sa)) < 0) {

The bridge is falsly dropping ipv6 mulitcast packets if there is:
1. No ipv6 address assigned on the brigde.
2. No external mld querier present.
3. The internal querier enabled.
When the bridge fails to build mld queries, because it has no
ipv6 address, it slilently returns, but keeps the local querier enabled.
This specific case causes confusing packet loss.
Ipv6 multicast snooping can only work if:
a) An external querier is present
OR
b) The bridge has an ipv6 address an is capable of sending own queries
Otherwise it has to forward/flood the ipv6 multicast traffic,
because snooping cannot work.
This patch fixes the issue by adding a flag to the bridge struct that
indicates that there is currently no ipv6 address assinged to the bridge
and returns a false state for the local querier in
__br_multicast_querier_exists().
Special thanks to Linus Lüssing.

mlx5_wq_ll_create()
* Update the failure warn messages with _node postfix for

bgmac_open() calls phy_start() to initialize the PHY state machine,
which will set the interface's carrier state accordingly, no need to
force that as this could be conflicting with the PHY state determined by

| | | | | | | | | | | | | | | | | | | | | |
Since commit 7bb11dc9f59d ("bonding: unify all places where
actor-oper key needs to be updated."), the logic in bonding to handle
selection between multiple aggregators has not functioned.
This affects only configurations wherein the bonding slaves
connect to two discrete aggregators (e.g., two independent switches, each
with LACP enabled), thus creating two separate aggregation groups within a
single bond.
The cause is a change in 7bb11dc9f59d to no longer set
AD_PORT_BEGIN on a port after a link state change, which would cause the
port to be reselected for attachment to an aggregator as if were newly
added to the bond. We cannot restore the prior behavior, as it
contradicts IEEE 802.1AX 5.4.12, which requires ports that "become
inoperable" (lose carrier, setting port_enabled=false as per 802.1AX
5.4.7) to remain selected (i.e., assigned to the aggregator). As the port
now remains selected, the aggregator selection logic is not invoked.
A side effect of this change is that aggregators in bonding will
now contain ports that are link down. The aggregator selection logic
does not currently handle this situation correctly, causing incorrect
aggregator selection.
This patch makes two changes to repair the aggregator selection
logic in bonding to function as documented and within the confines of the
standard:
First, the aggregator selection and related logic now utilizes the
number of active ports per aggregator, not the number of selected ports
(as some selected ports may be down). The ad_select "bandwidth" and
"count" options only consider ports that are link up.
Second, on any carrier state change of any slave, the aggregator
selection logic is explicitly called to insure the correct aggregator is
active.

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.

with the commit 8c14586fc320 ("net: ipv6: Use passed in table for
nexthop lookups"), net hop lookup is first performed on route creation
in the passed-in table.
However device match is not enforced in table lookup, so the found
route can be later discarded due to egress device mismatch and no
global lookup will be performed.
This cause the following to fail:
ip link add dummy1 type dummy
ip link add dummy2 type dummy
ip link set dummy1 up
ip link set dummy2 up
ip route add 2001:db8:8086::/48 dev dummy1 metric 20
ip route add 2001:db8:d34d::/64 via 2001:db8:8086::2 dev dummy1 metric 20
ip route add 2001:db8:8086::/48 dev dummy2 metric 21
ip route add 2001:db8:d34d::/64 via 2001:db8:8086::2 dev dummy2 metric 21
RTNETLINK answers: No route to host
This change fixes the issue enforcing device lookup in

For 'real' hardware CAN devices the netlink interface is used to set CAN
specific communication parameters. Real CAN hardware can not be created nor
removed with the ip tool ...
This patch adds a private dellink function for the CAN device driver interface
that does just nothing.
It's a follow up to commit 993e6f2fd ("can: fix oops caused by wrong rtnl
newlink usage") but for dellink.

With upstream commit bb208f144cf3f59 (can: fix handling of unmodifiable

When invoking 'ip link set can0 type can' without any configuration data
can_validate() tries to validate the content without taking into account that
there's totally no content. This patch adds a check for missing content.

By default, mdiobus_alloc() sets the PHYs to polling mode, but a
pointer size memcpy means that a couple IRQs end up being overwritten
with a value of 0. This means that PHY_POLL is disabled and results
in unpredictable behavior depending on the PHY's location on the
MDIO bus. Remove that memcpy and the now unused phy_irq member to
force the SMSC911x PHYs into polling mode 100% of the time.

commit 5c86d97bcc1d ("ath10k: combine txrx and replenish task")
introduced deadlock while processing rx in order indication message
for qca6174 based devices. While merging replenish and txrx tasklets,
replenish task should be called out of htt rx ring locking since it
is also try to acquire the same lock.
Unfortunately this issue is not exposed by other solutions (qca988x,
qca99x0 & qca4019), as rx_in_ord_ind message is specific to qca6174
based devices. This patch fixes

This looks like a regression from commit c4cdf753ed42 ("ath10k: move
fw_features to struct ath10k_fw_file"), we were printing the features from a
wrong struct.

path_b_ok is being assigned but immediately after path_a_ok is being
compared to the value 0x03. This appears to be a typo on the
variable name, compare path_b_ok instead.

The FW expect the driver to set the encryption algorithm type when
installing the IGTK key in the HW.
Currently when installing CMAC IGTK key we don't set the algorithm type
and as a result the FW fails to calculate the MIC of multicast management
frames.
Fix it.

The 16 seconds timeout we were using turned out to be too short.
Recalculations by system show that the total time in both bands should
be < 18.5 seconds, even in the slowest cases (e.g. DCM P2P with
DTIM=2). Rounding it up to 20 seconds for a bit more safety.

Alexey reported that we have GFP_KERNEL allocation when
holding the spinlock tcf_lock. Actually we don't have
to take that spinlock for all the cases, especially
for the new one we just create. To modify the existing
actions, we still need this spinlock to make sure
the whole update is atomic.
For net-next, we can get rid of this spinlock because
we already hold the RTNL lock on slow path, and on fast
path we can use RCU to protect the metalist.
Joint work with Jamal.

Blair Steven noticed that ESN in conjunction with UDP encapsulation
is broken because we set the temporary ESP header to the wrong spot.
This patch fixes this by first of all using the right spot, i.e.,
4 bytes off the real ESP header, and then saving this information
so that after encryption we can restore it properly.

This allows a clean shutdown, even if some netdev clients do not
release their reference from this netdev. It is enough to release
the HW resources only as the kernel is shutting down.

When extracting an individual message from a received "bundle" buffer,
we just create a clone of the base buffer, and adjust it to point into
the right position of the linearized data area of the latter. This works
well for regular message reception, but during periods of extremely high
load it may happen that an extracted buffer, e.g, a connection probe, is
reversed and forwarded through an external interface while the preceding
extracted message is still unhandled. When this happens, the header or
data area of the preceding message will be partially overwritten by a
MAC header, leading to unpredicatable consequences, such as a link
reset.
We now fix this by ensuring that the msg_reverse() function never
returns a cloned buffer, and that the returned buffer always contains
sufficient valid head and tail room to be forwarded.

It is caused by a missing free in the ->release path. So fix it by
providing seq_release_net as the ->release method.

Both dev_uc_sync_multiple() and dev_mc_sync_multiple() require the
source device to be locked by netif_addr_lock_bh(), but this is missing
in team's enslave function, so add it.
This fixes the following lockdep warning:
Possible interrupt unsafe locking scenario:
CPU0 CPU1
---- ----
lock(_xmit_ETHER/1);
local_irq_disable();
lock(&(&mc->mca_lock)->rlock);
lock(&team_netdev_addr_lock_key);
<Interrupt>
lock(&(&mc->mca_lock)->rlock);
*** DEADLOCK ***

====================
pull-request: can 2016-06-20
this is a pull request of 3 patches for the upcoming linux-4.7 release.
The first patch is by Thor Thayer for the c_can/d_can driver. It fixes the
registar access on Altera Cyclone devices, which caused CAN frames to have 0x0
in the first two bytes incorrectly. Wolfgang Grandegger's patch for the at91
driver fixes a hanging driver under high bus load situations. A patch for the
gs_usb driver by Maximilian Schneider adds support for the bytewerk.org
candleLight interface.

At high bus load it could happen that "at91_poll()" enters with all RX
message boxes filled up. If then at the end the "quota" is exceeded as
well, "rx_next" will not be reset to the first RX mailbox and hence the
interrupts remain disabled.

access
When testing CAN write floods on Altera's CycloneV, the first 2 bytes
are sometimes 0x00, 0x00 or corrupted instead of the values sent. Also
observed bytes 4 & 5 were corrupted in some cases.
The D_CAN Data registers are 32 bits and changing from 16 bit writes to
32 bit writes fixes the problem.
Testing performed on Altera CycloneV (D_CAN). Requesting tests on other
C_CAN & D_CAN platforms.

This series contains several small fixes to driver behavior
[4th patch is the only one containing a 'fatal' fix, but the error
is only theoretical for qede; if would require another protocol
