702c2f646d mptcp: netlink: allow userspace-driven subflow establishment
This allows userspace to tell kernel to add a new subflow to an existing
mptcp connection.

Userspace provides the token to identify the mptcp-level connection
that needs a change in active subflows and the local and remote
addresses of the new or the to-be-removed subflow.

MPTCP_PM_CMD_SUBFLOW_CREATE requires the following parameters:
{ token, { loc_id, family, loc_addr4 | loc_addr6 }, { family, rem_addr4 |
rem_addr6, rem_port }

MPTCP_PM_CMD_SUBFLOW_DESTROY requires the following parameters:
{ token, { family, loc_addr4 | loc_addr6, loc_port }, { family, rem_addr4 |
rem_addr6, rem_port }

982f17ba1a mptcp: netlink: split mptcp_pm_parse_addr into two functions
Next patch will need to parse MPTCP_PM_ATTR_ADDR attributes and
fill an mptcp_addr_info structure from a different genl command
callback.

To avoid copy-paste, split the existing function to a helper
that does the common part and then call the helper from the
(renamed)mptcp_pm_parse_entry function.

8b20137012 mptcp: read attributes of addr entries managed by userspace PMs
This change introduces a parallel path in the kernel for retrieving
the local id, flags, if_index for an addr entry in the context of
an MPTCP connection that's being managed by a userspace PM. The
userspace and in-kernel PM modes deviate in their procedures for
obtaining this information.

4638de5aef mptcp: handle local addrs announced by userspace PMs
This change adds an internal function to store/retrieve local
addrs announced by userspace PM implementations to/from its kernel
context. The function addresses the requirements of three scenarios:
1) ADD_ADDR announcements (which require that a local id be
provided), 2) retrieving the local id associated with an address,
and also where one may need to be assigned, and 3) reissuance of
ADD_ADDRs when there's a successful match of addr/id.

The list of all stored local addr entries is held under the
MPTCP sock structure. Memory for these entries is allocated from
the sock option buffer, so the list of addrs is bounded by optmem_max.
The list if not released via REMOVE_ADDR signals is ultimately
freed when the sock is destructed.

5bb99fd409 powerpc/4xx/cpm: Fix return value of __setup() handler
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.

A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) argument or environment
strings.

Also, error return codes don't mean anything to obsolete_checksetup() --
only non-zero (usually 1) or zero. So return 1 from cpm_powersave_off().

86af062f40 mac80211: Reset MBSSID parameters upon connection
Currently MBSSID parameters in struct ieee80211_bss_conf
are not reset upon connection. This could be problematic
with some drivers in a scenario where the device first
connects to a non-transmit BSS and then connects to a
transmit BSS of a Multi BSS AP. The MBSSID parameters
which are set after connecting to a non-transmit BSS will
not be reset and the same parameters will be passed on to
the driver during the subsequent connection to a transmit
BSS of a Multi BSS AP.

For example, firmware running on the ath11k device uses the
Multi BSS data for tracking the beacon of a non-transmit BSS
and reports the driver when there is a beacon miss. If we do
not reset the MBSSID parameters during the subsequent
connection to a transmit BSS, then the driver would have
wrong MBSSID data and FW would be looking for an incorrect
BSSID in the MBSSID beacon of a Multi BSS AP and reports
beacon loss leading to an unstable connection.

Reset the MBSSID parameters upon every connection to solve this
problem.

a2ece1f512 powerpc: use strscpy to replace strlcpy
The strlcpy should not be used because it doesn't limit the source
length. As linus says, it's a completely useless function if you
can't implicitly trust the source string - but that is almost always
why people think they should use it! All in all the BSD function
will lead some potential bugs.

But the strscpy doesn't require reading memory from the src string
beyond the specified "count" bytes, and since the return value is
easier to error-check than strlcpy()'s. In addition, the implementation
is robust to the string changing out from underneath it, unlike the
current strlcpy() implementation.

Thus, We prefer using strscpy instead of strlcpy.

59510820ff powerpc/mpc52xx: Fix some pr_debug() issues
Fix some pr_debug() issues in mpc52xx_pci.c:

- use "%pr" to print struct resource entries
- use "%pa" to print a resource_size_t (phys_addr_t)

The latter two fix several build warnings:

Include linux/mc146818rtc.h in powerpc kernel/time.c where 'rtc_lock' is
declared. And remove duplicated declaration of 'rtc_lock' in powerpc
platforms/chrp/time.c because it has included linux/mc146818rtc.h.

Move 'dtl_consumer' definition after "include <asm/dtl.h>" because it is

Replace the .round_rate() callback with .determine_rate() which can
consider max_rate imposed by clk_set_max_rate() while rounding the clock
rate.

Note that if the .determine_rate() callback is defined it will be called
instead of the .round_rate() callback when calling clk_round_rate(). By
using .determine_rate(), the maximum rate returned when calling
clk_round_rate() is now limited by the current max_rate.
