Now that there's the general purpose hci_send_to_channel() API it will
do the exact same thing as queue_monitor_skb() when passed the monitor
HCI channel. This patch removes queue_monitor_skb() and replaces any
users of it with calls to hci_send_to_channel().

The hci_send_to_control() can be made more general purpose with a small
change of passing the desired HCI channel as a parameter to it. This
allows using it for the monitor channel as well as e.g. 6lowpan in the
future.

The only reason the SMP code is essentially duplicating the
hci_copy_identity_addr() function is that the helper returns the address
type in the HCI format rather than the three-value format expected by
l2cap_chan. This patch converts the SMP code to use the helper and then
do a simple conversion from one address type to another.

Pull Ceph changes from Sage Weil:
"On the RBD side, there is a conversion to blk-mq from Christoph,
several long-standing bug fixes from Ilya, and some cleanup from
Rickard Strandqvist.
On the CephFS side there is a long list of fixes from Zheng, including
improved session handling, a few IO path fixes, some dcache management
correctness fixes, and several blocking while !TASK_RUNNING fixes.
The core code gets a few cleanups and Chaitanya has added support for
TCP_NODELAY (which has been used on the server side for ages but we
somehow missed on the kernel client).
There is also an update to MAINTAINERS to fix up some email addresses
and reflect that Ilya and Zheng are doing most of the maintenance for
RBD and CephFS these days. Do not be surprised to see a pull request
come from one of them in the future if I am unavailable for some
reason"

The gnet_stats_copy_app() function gets called, more often than not, with its
second argument a pointer to an automatic variable in the caller's stack.
Therefore, to avoid copying garbage afterwards when calling
gnet_stats_finish_copy(), this data is better copied to a dynamically allocated
memory that gets freed after use.

Changing the HS setting requires that SSP is enabled, however so far the

It turns out it's possible to get __remove_osd() called twice on the
same OSD. That doesn't sit well with rb_erase() - depending on the
shape of the tree we can get a NULL dereference, a soft lockup or
a random crash at some point in the future as we end up touching freed
memory. One scenario that I was able to reproduce is as follows:
<osd3 is idle, on the osd lru list>
<con reset - osd3>
con_fault_finish()
osd_reset()
<osdmap - osd3 down>
ceph_osdc_handle_map()
<takes map_sem>
kick_requests()
<takes request_mutex>
reset_changed_osds()
__reset_osd()
__remove_osd()
<releases request_mutex>
<releases map_sem>
<takes map_sem>
<takes request_mutex>
__kick_osd_requests()
__reset_osd()
__remove_osd() <-- !!!
A case can be made that osd refcounting is imperfect and reworking it
would be a proper resolution, but for now Sage and I decided to fix
this by adding a safe guard around __remove_osd().

This patch moves all the disconn_cfm callbacks to be based on the hci_cb
list. This means making l2cap_disconn_cfm private to l2cap_core.c and
sco_conn_cb private to sco.c respectively. Since the hci_conn type
filtering isn't done any more on the wrapper level the callbacks
themselves need to check that they were passed a relevant type of
connection.

When processing hci_cb entries we want first registered callbacks to be
called first and later ones later. This is because eventually the L2CAP
callbacks that are part of the core will use this list and get
registered first. To keep the same order of calling L2CAP callbacks
before e.g. RFCOMM the order of elements needs to be this way.

Our UC-KLEE tool found a kernel memory leak of 512 bytes (on x86_64) for
each call to gssp_accept_sec_context_upcall()
(net/sunrpc/auth_gss/gss_rpc_upcall.c). Since it appears that this call
can be triggered by remote connections (at least, from a cursory a
glance at the call chain), it may be exploitable to cause kernel memory
exhaustion. We found the bug in kernel 3.16.3, but it appears to date
back to commit 9dfd87da1aeb0fd364167ad199f40fe96a6a87be (2013-08-20).
The gssp_accept_sec_context_upcall() function performs a pair of calls
to gssp_alloc_receive_pages() and gssp_free_receive_pages(). The first
allocates memory for arg->pages. The second then frees the pages
pointed to by the arg->pages array, but not the array itself.

If the phy interface mode is not found in devicetree, or if devicetree
is not configured, of_get_phy_mode returns -ENODEV. The current code
sets the phy interface mode to the return value from of_get_phy_mode
without checking if it is valid.
This invalid phy interface mode is passed as parameter to of_phy_connect
or to phy_connect_direct. This sets the phy interface mode to the invalid
value, which in turn causes problems for any code using phydev->interface.

given:
-A INPUT -m recent --update --seconds 30 --hitcount 4
and
iptables-save > foo
then
iptables-restore < foo
will fail with:
kernel: xt_recent: hitcount (4) is larger than packets to be remembered (4) for table DEFAULT
Even when the check is fixed, the restore won't work if the hitcount is
increased to e.g. 6, since by the time checkentry runs it will find the
'old' incarnation of the table.
We can avoid this by increasing the maximum threshold silently; we only
have to rm all the current entries of the table (these entries would
not have enough room to handle the increased hitcount).
This even makes (not-very-useful)
-A INPUT -m recent --update --seconds 30 --hitcount 4
-A INPUT -m recent --update --seconds 30 --hitcount 42
work.

On BR/EDR the L2CAP channel instances for fixed channels have so far
been marked as ready only once the L2CAP information req/rsp procedure
is complete and we have the fixed channel mask. This could however lead
to data being dropped if we receive it on the channel before knowing the
remote mask.
Since it is valid for a remote to send data this early, simply assume
that the channel is supported when we receive data on it. So far this
hasn't been noticed much because of limited use of fixed channels on
BR/EDR, but e.g. with SMP over BR/EDR this is already now visible with
automated tests failing randomly.

Ignacy reported that when eth0 is down and add a vlan device
on top of it like:
ip link add link eth0 name eth0.1 up type vlan id 1
We will get a refcount leak:
unregister_netdevice: waiting for eth0.1 to become free. Usage count = 2
The problem is when rtnl_configure_link() fails in rtnl_newlink(),
we simply call unregister_device(), but for stacked device like vlan,
we almost do nothing when we unregister the upper device, more work
is done when we unregister the lower device, so call its ->dellink().

ipv6_cow_metrics() currently assumes only DST_HOST routes require
dynamic metrics allocation from inetpeer. The assumption breaks
when ndisc discovered router with RTAX_MTU and RTAX_HOPLIMIT metric.
Refer to ndisc_router_discovery() in ndisc.c and note that dst_metric_set()
is called after the route is created.
This patch creates the metrics array (by calling dst_cow_metrics_generic) in
ipv6_cow_metrics().
Test:
radvd.conf:
interface qemubr0
{
AdvLinkMTU 1300;
AdvCurHopLimit 30;
prefix fd00:face:face:face::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr off;
};
};
Before:
[root@qemu1 ~]# ip -6 r show | egrep -v unreachable

fe80::/64 dev eth0 proto kernel metric 256

This patch adds other known rfc6282 compression formats to the nhc
framework. These compression formats are known but not implemented yet.
For now this is useful to printout a warning which compression format
isn't supported.

This patch move UDP header compression and uncompression into the
generic 6LoWPAN nhc header compression layer. Moreover this patch
activates the nhc layer compression in iphc compression and
uncompression functions.

This patch adds a generic next header compression layer interface. There
exists various methods to do a header compression after 6LoWPAN header
to save payload. This introduce a generic nhc header which allow a
simple adding of a new header compression format instead of a static
implementation inside the 6LoWPAN header compression and uncompression
function.

printk and friends can now format bitmaps using '%*pb[l]'. cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

If user space is trying to pair on not enabled transport
MGMT_STATUS_REJECT will be returned.
If user space is trying to pair on transport which controller does not
support, MGMT_STATUS_NOT_SUPPORTED will be returned.
Having separate error code for that scenario might be useful for
debugging at least.

Kernel gives possibility to enable/disable LE host support.
There is flag HCI_LE_ENABLED which is set when this support is enabled
and some parts of the code checks this flag e.g. SMP
However it is still possible to make LE connection if LE Host support is
disabled, what might be confused for remote device.
This patch makes sure that kernel will not send HCI LE Create Connection
if LE HOST support is not enabled.

6LoWPAN currently doesn't supports x-netns and works only in init_net.
With this patch, we ensure that:
- the wpan interface cannot be moved to another netns;
- the 6lowpan interface cannot be moved to another netns;
- the wpan interface is in the same netns than the 6lowpan interface;
- the 6lowpan interface is in init_net.

Other code that accesses rq_bc_pa_list holds xprt->bc_pa_lock.
