net: systemport: Fix padding vs. TSB insertion
This patch series fixes how we pad the packets submitted to the SYSTEMPORT
adapter, and how the transmit status block (prepended 8 bytes) fits in the
picture. The first patch is not technically a bug fix, but is required for the
second path to be applied and to greatly simplify the skb length calculation.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

xfs: fix crash and data corruption due to removal of busy COW extents
There is a race window between write_cache_pages calling
clear_page_dirty_for_io and XFS calling set_page_writeback, in which
the mapping for an inode is tagged neither as dirty, nor as writeback.
If the COW shrinker hits in exactly that window we'll remove the delayed
COW extents and writepages trying to write it back, which in release
kernels will manifest as corruption of the bmap btree, and in debug
kernels will trip the ASSERT about now calling xfs_bmapi_write with the
COWFORK flag for holes. A complex customer load manages to hit this
window fairly reliably, probably by always having COW writeback in flight
while the cow shrinker runs.
This patch adds another check for having the I_DIRTY_PAGES flag set,
which is still set during this race window. While this fixes the problem
I'm still not overly happy about the way the COW shrinker works as it
still seems a bit fragile.

All the imx6 weim dts users explicitily provide 'status = "okay"', so

If a board does not use the weim driver it will not describe its 'ranges'

igmp: Make igmp group member RFC 3376 compliant
5.2. Action on Reception of a Query
When a system receives a Query, it does not respond immediately.
Instead, it delays its response by a random amount of time, bounded
by the Max Resp Time value derived from the Max Resp Code in the
received Query message. A system may receive a variety of Queries on
different interfaces and of different kinds (e.g., General Queries,
Group-Specific Queries, and Group-and-Source-Specific Queries), each
of which may require its own delayed response.
Before scheduling a response to a Query, the system must first
consider previously scheduled pending responses and in many cases
schedule a combined response. Therefore, the system must be able to
maintain the following state:
o A timer per interface for scheduling responses to General Queries.
o A per-group and interface timer for scheduling responses to Group-
Specific and Group-and-Source-Specific Queries.
o A per-group and interface list of sources to be reported in the
response to a Group-and-Source-Specific Query.
When a new Query with the Router-Alert option arrives on an
interface, provided the system has state to report, a delay for a
response is randomly selected in the range (0, [Max Resp Time]) where
Max Resp Time is derived from Max Resp Code in the received Query
message. The following rules are then used to determine if a Report
needs to be scheduled and the type of Report to schedule. The rules
are considered in order and only the first matching rule is applied.
1. If there is a pending response to a previous General Query
scheduled sooner than the selected delay, no additional response
needs to be scheduled.
2. If the received Query is a General Query, the interface timer is
used to schedule a response to the General Query after the
selected delay. Any previously pending response to a General
Query is canceled.
--8<--
Currently the timer is rearmed with new random expiration time for
every incoming query regardless of possibly already pending report.
Which is not aligned with the above RFE.
It also might happen that higher rate of incoming queries can
postpone the report after the expiration time of the first query
causing group membership loss.
Now the per interface general query timer is rearmed only
when there is no pending report already scheduled on that interface or
the newly selected expiration time is before the already pending
scheduled report.

A similar case arises in the clock disable path.
To enable such usage, make __clk_{enable,disable} functions

it was shared), leading to an invalid pointer.
This can lead to use-after-free and also later crashes since the
real SKB's info->hw_queue doesn't get initialized properly.
Fix this by assigning info only later, when it's needed, after the
skb replacement (may have) happened.

Similarly to the aemif clock - this screws up the linked list of clock
children. Create a separate clock for mdio inheriting the rate from
emac_clk.

ARM: davinci: da850: fix infinite loop in clk_set_rate()
The aemif clock is added twice to the lookup table in da850.c. This
breaks the children list of pll0_sysclk3 as we're using the same list
links in struct clk. When calling clk_set_rate(), we get stuck in
propagate_rate().
Create a separate clock for nand, inheriting the rate of the aemif
clock and retrieve it in the davinci_nand module.

ARM: i.MX: remove map_io callback
There is no need to define map_io only for debug_ll_io_init() since it
is already called in devicemaps_init() if map_io is NULL.
Apart from that, for NOMMU build debug_ll_io_init() is a nop which
leads to following error:

====================
l2tp: socket lookup fixes for l2tp_ip and l2tp_ip6
There are still some cases that aren't correctly handled in the socket
lookup functions of l2tp_ip and l2tp_ip6. This series fixes lookups for
connected sockets and for sockets bound to the IPv6 unspecified
address.
bind() and connect() should now work as expected on IPPROTO_L2TP
sockets. Extra features, like SO_REUSEADDR, remain unsupported.
The matching conditions in __l2tp_ip6_bind_lookup() and
__l2tp_ip_bind_lookup() are getting hard to read. I've kept the single
test approach to make the intend of the patches clear. I'll split the
conditionals once these fixes reach net-next.

l2tp: take remote address into account in l2tp_ip and l2tp_ip6 socket lookups
For connected sockets, __l2tp_ip{,6}_bind_lookup() needs to check the
remote IP when looking for a matching socket. Otherwise a connected
socket can receive traffic not originating from its peer.
Drop l2tp_ip_bind_lookup() and l2tp_ip6_bind_lookup() instead of
updating their prototype, as these functions aren't used.

l2tp: consider '::' as wildcard address in l2tp_ip6 socket lookup
An L2TP socket bound to the unspecified address should match with any
address. If not, it can't receive any packet and __l2tp_ip6_bind_lookup()
can't prevent another socket from binding on the same device/tunnel ID.
While there, rename the 'addr' variable to 'sk_laddr' (local addr), to
make following patch clearer.
