144adc655f Merge branch 'ipv6-v4mapped'
Jonathan T. Leighton says:

====================
IPv4-mapped on wire, :: dst address issue

Under some circumstances IPv6 datagrams are sent with IPv4-mapped IPv6
addresses as the source. Given an IPv6 socket bound to an IPv4-mapped
IPv6 address, and an IPv6 destination address, both TCP and UDP will
will send packets using the IPv4-mapped IPv6 address as the source. Per
RFC 6890 (Table 20), IPv4-mapped IPv6 source addresses are not allowed
in an IP datagram. The problem can be observed by attempting to
connect() either a TCP or UDP socket, or by using sendmsg() with a UDP
socket. The patch is intended to correct this issue for all socket
types.

linux follows the BSD convention that an IPv6 destination address
specified as in6addr_any is converted to the loopback address.
Currently, neither TCP nor UDP consider the possibility that the source
address is an IPv4-mapped IPv6 address, and assume that the appropriate
loopback address is ::1. The patch adds a check on whether or not the
source address is an IPv4-mapped IPv6 address and then sets the
destination address to either ::ffff:127.0.0.1 or ::1, as appropriate.

052d2369d1 ipv6: Handle IPv4-mapped src to in6addr_any dst.
This patch adds a check on the type of the source address for the case
where the destination address is in6addr_any. If the source is an
IPv4-mapped IPv6 source address, the destination is changed to
::ffff:127.0.0.1, and otherwise the destination is changed to ::1. This
is done in three locations to handle UDP calls to either connect() or
sendmsg() and TCP calls to connect(). Note that udpv6_sendmsg() delays
handling an in6addr_any destination until very late, so the patch only
needs to handle the case where the source is an IPv4-mapped IPv6
address.

17f84b793c spi: lantiq-ssc: add support for Lantiq SSC SPI controller
This driver supports the Lantiq SSC SPI controller in master
mode. This controller is found on Intel (former Lantiq) SoCs like
the Danube, Falcon, xRX200, xRX300.

The hardware uses two hardware FIFOs one for received and one for
transferred bytes. When the driver writes data into the transmit FIFO
the complete word is taken from the FIFO into a shift register. The
data from this shift register is then written to the wire. This driver
uses the interrupts signaling the status of the FIFOs and not the shift
register. It is also possible to use the interrupts for the shift
register, but they will send a signal after every word. When using the
interrupts for the shift register we get a signal when the last word is
written into the shift register and not when it is written to the wire.
After all FIFOs are empty the driver busy waits till the hardware is
not busy any more and returns the transfer status.

fed06ee89b net/mlx5e: Disable preemption when doing TC statistics upcall

net/sched/act_mirred.c) code uses this_cpu logic, e.g

 _bstats_cpu_update(this_cpu_ptr(a->cpu_bstats), bytes, packets)

per the kernel documention, preemption should be disabled, add that.

Before the fix, when running with CONFIG_PREEMPT set, we get a

a748d60df3 IB/mlx4: Take source GID by index from HW GID table
Previously, we used the HW GID index in order to search the source GID
in the software GID cached table. In some cases, for example when
the MAC Address of the network interface is changed, the GID cached table
saves the old-IPv6-link-local GID at the end of the table.

When returning the old MAC address, the software GID cached table tries
to add the new IPv6-link-local GID, and when it identifies that the GID
already exists, the software GID cached does not add it. Thus a mismatch
occurs between the HW and the SW GID tables.

It resulted with sending traffic with the wrong source GID.

This commit fixes the issue by taking both from the HW table.

The problem can be reproduced with the following scenario:
Client:
    # ifconfig ens6 2.2.2.5
    # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64
    # ifconfig ens6 hw ether f4:52:14:61:a0:71
    # ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64

c4550c63b3 IB: Query ports via the core instead of direct into the driver
Change the drivers to call ib_query_port in their get port
immutable handler instead of their own query port handler.

Doing this required to set the core cap flags of this device
before the ib_query_port call is made, since the IB core might
need these caps to serve the port query.

Drivers are ensured by the IB core that the port attributes passed
to the port query verb implementation are zero, and hence we
removed the zeroing from the drivers.

This patch doesn't add any new functionality.

ebaaee253a IB/core: Expose vlan offloads capabilities
Expose raw packet capabilities in the core layer to enable a device
to report it.
Two existing capabilities, scatter FCS and IP CSUM were added to this
field for a better user experience by exposing the raw packet caps
from one location.
This field will serve also for future capabilities for raw packet QP.

A new capability was introduced - cvlan stripping, which is the
device's ability to remove cvlan tag from an incoming packet and
report it in the matching work completion.

23a6964e3a IB/mlx5: Add port counter support for Receive WQs
Counters weren't updated due to Receive WQs' traffic since the
counter-id was not associated with the RQ.

Added support for associating the q-counter-id with the Receive WQ.
The attachment is done only when changing WQ's state from RESET to
READY in modify-WQ command.

FW support is required for the above, without this support
Receive WQ counters will not count.

[  160.317241] ---[ end trace d6a773a375c810a5 ]---

The problem is that when the kernel tries to truncate an inode in
ext4_truncate(), it tries to clear any on-disk data beyond i_size.
Without the encryption key, it can't do that, and so it triggers a
BUG.

E2fsck does *not* provide this service, and in practice most file
systems have their orphan list processed by e2fsck, so to avoid
crashing, this patch skips this step if we don't have access to the
encryption key (which is the case when processing the orphan list; in
all other cases, we will have the encryption key, or the kernel
wouldn't have allowed the file to be opened).

An open question is whether the fact that e2fsck isn't clearing the
bytes beyond i_size causing problems --- and if we've lived with it
not doing it for so long, can we drop this from the kernel replay of
the orphan list in all cases (not just when we don't have the key for
encrypted inodes).
