Bluetooth: Fix limited discoverable mode for Zeevo modules
There is an old Panasonic module with a Zeevo chip in there that is
not really operating according to Bluetooth core specification when
it comes to setting the IAC LAP for limited discoverable mode.
For reference, this is the vendor information about this module:
< HCI Command: Read Local Version Information (0x04|0x0001) plen 0
> HCI Event: Command Complete (0x0e) plen 12
Read Local Version Information (0x04|0x0001) ncmd 1
Status: Success (0x00)
HCI version: Bluetooth 1.2 (0x02) - Revision 196 (0x00c4)
LMP version: Bluetooth 1.2 (0x02) - Subversion 61 (0x003d)
Manufacturer: Zeevo, Inc. (18)
The module reports only the support for one IAC at a time. And that
is totally acceptable according to the Bluetooth core specification
since the minimum supported IAC is only one.
< HCI Command: Read Number of Supported IAC (0x03|0x0038) plen 0
> HCI Event: Command Complete (0x0e) plen 5
Read Number of Supported IAC (0x03|0x0038) ncmd 1
Status: Success (0x00)
Number of IAC: 1
The problem arises when trying to program two IAC into the module
on a controller that only supports one.
< HCI Command: Write Current IAC LAP (0x03|0x003a) plen 7
Number of IAC: 2
Access code: 0x9e8b00 (Limited Inquiry)
Access code: 0x9e8b33 (General Inquiry)
> HCI Event: Command Status (0x0f) plen 4
Write Current IAC LAP (0x03|0x003a) ncmd 1
Status: Unknown HCI Command (0x01)
While this looks strange, but according to the Bluetooth core
specification it is a legal operation. The controller has to
ignore the other values and only program as many as it supports.
This command shall clear any existing IACs and stores Num_Current_IAC
and the IAC_LAPs in to the controller. If Num_Current_IAC is greater
than Num_Support_IAC then only the first Num_Support_IAC shall be
stored in the controller, and a Command Complete event with error
code Success (0x00) shall be generated.
This specific controller has a bug here and just returns an error. So
in case the number of supported IAC is less than two and the limited
discoverable mode is requested, now only the LIAC is written to
the controller.
< HCI Command: Write Current IAC LAP (0x03|0x003a) plen 4
Number of IAC: 1
Access code: 0x9e8b00 (Limited Inquiry)
> HCI Event: Command Complete (0x0e) plen 4
Write Current IAC LAP (0x03|0x003a) ncmd 1
Status: Success (0x00)
All other controllers that only support one IAC seem to handle this
perfectly fine, but this fix will only write the LIAC for these
controllers as well.

Instead of handling icmp packets only up to length of icmp_packet_rr,
the code should handle any icmp length size. Therefore the length
truncating is moved to when the packet is actually sent to userspace
(this does not support lengths longer than icmp_packet_rr yet). Longer
packets are forwarded without truncating.
This patch also cleans up some parts where the icmp header struct could
be used instead of other icmp_packet(_rr) structs to make the code more

batman-adv: include the sync-flags when compute the global/local table CRC
Flags covered by TT_SYNC_MASK are kept in sync among the
nodes in the network and therefore they have to be
considered while computing the global/local table CRC.
In this way a generic originator is able to understand if
its table contains the correct flags or not.
Bits from 4 to 7 in the TT flags fields are now reserved for
"synchronized" flags only.
This allows future developers to add more flags of this type
without breaking compatibility.
It's important to note that not all the remote TT flags are
synchronised. This comes from the fact that some flags are
used to inject an information once only.

current routing algorithm being used. To easily make this
mechanism routing algorithm agnostic add a orig_node
specific API that each algorithm can populate with its own
routines.
Such routines are then invoked by the code when needed,
without knowing which routing algorithm is currently in use
With this patch 3 API functions are added:
- orig_free (to free routing depending internal structs)
- orig_add_if (to change the inner state of an orig_node
when a new hard interface is added)
- orig_del_if (to change the inner state of an orig_node

Let's say the disk_events_workfn() calls sd_check_events() which tries
to send test_unit_ready() and because of sd_revalidate_disk() trying to
send another commands the test_unit_ready() might be re-queued as the
tagged command queuing is disabled.
The problem is, the test_unit_ready request doesn't get counted the
first time it is queued, so the later decrement of q->nr_pending in
blk_pm_requeue_request makes it unbalanced.
Fix this by calling blk_pm_runtime_init before add_disk so that all
requests initiated there will all be counted.
