commit c17c3cdff10b9f59ef1244a14604f10949f17117 upstream.
When the memory is exhausted, then we will fail to add the NFT_MSG_NEWSET
transaction. In such case, we should destroy the set before we free it.

commit 830218c1add1da16519b71909e5cf21522b7d062 upstream.
rt6_add_route_info and rt6_add_dflt_router were updated to pull the FIB
table from the device index, but the corresponding rt6_get_route_info
and rt6_get_dflt_router functions were not leading to the failure to
process RA's:
ICMPv6: RA: ndisc_router_discovery failed to add default route
Fix the 'get' functions by using the table id associated with the
device when applicable.
Also, now that default routes can be added to tables other than the
default table, rt6_purge_dflt_routers needs to be updated as well to
look at all tables. To handle that efficiently, add a flag to the table
denoting if it is has a default route via RA.

commit 4f7f34eaab9f68c9bcd45386b15c414c38b40587 upstream.
ifupdown2 found a kernel bug with IPv6 routes and movement from the main
table to the VRF table. Sequence of events:
Create the interface and add addresses:
ip link add dev eth4.105 link eth4 type vlan id 105
ip addr add dev eth4.105 8.105.105.10/24
ip -6 addr add dev eth4.105 2008:105:105::10/64
At this point IPv6 has inserted a prefix route in the main table even
though the interface is 'down'. From there the VRF device is created:
ip link add dev vrf105 type vrf table 105
ip addr add dev vrf105 9.9.105.10/32
ip -6 addr add dev vrf105 2000:9:105::10/128
ip link set vrf105 up
Then the interface is enslaved, while still in the 'down' state:
ip link set dev eth4.105 master vrf105
Since the device is down the VRF driver cycling the device does not
send the NETDEV_UP and NETDEV_DOWN but rather the NETDEV_CHANGE event
which does not flush the routes inserted prior.
When the link is brought up
ip link set dev eth4.105 up
the prefix route is added in the VRF table, but does not remove
the route from the main table.
Fix by handling the NETDEV_CHANGEUPPER event similar what was implemented
for IPv4 in 7f49e7a38b77 ("net: Flush local routes when device changes vrf
association")

commit e895cdce683161081e3626c4f5a5c55cb72089f8 upstream.
In commit f02db315b8d8 ("ipv4: IP_TOS and IP_TTL can be specified as
ancillary data") Francesco added IP_TOS values specified as integer.
However, kernel sends to userspace (at recvmsg() time) an IP_TOS value
in a single byte, when IP_RECVTOS is set on the socket.
It can be very useful to reflect all ancillary options as given by the
kernel in a subsequent sendmsg(), instead of aborting the sendmsg() with
EINVAL after Francesco patch.
So this patch extends IP_TOS ancillary to accept an u8, so that an UDP
server can simply reuse same ancillary block without having to mangle
it.
Jesper can then augment
https://github.com/netoptimizer/network-testing/blob/master/src/udp_example02.c
to add TOS reflection ;)

commit fa17806cde76fb1087532f07e72aa757a30e0500 upstream.
inet_forward_change() runs with RTNL held.
We are allowed to sleep if required.
If we use __in_dev_get_rtnl() instead of __in_dev_get_rcu(),
we no longer have to use GFP_ATOMIC allocations in
inet_netconf_notify_devconf(), meaning we are less likely to miss
notifications under memory pressure, and wont touch precious memory
reserves either and risk dropping incoming packets.
inet_netconf_get_devconf() can also use GFP_KERNEL allocation.

This patch corrects the logic for the IPv4 parsing so that it is consistent
with how we handle IPv6. Specifically if we do not have the flow key
indicating we want the addresses we still may need to take a look at the IP
fragmentation bits and to see if we should stop after we have recognized
the L3 header.

[ Upstream commit e461bc9f9ab105637b86065d24b0b83f182d477c ]
Sed broke on some strings as it used colon as a separator.
I made it more robust by using \001, which is legit POSIX AFAIK.
E.g. ./config --set-str CONFIG_USBNET_DEVADDR "de:ad:be:ef:00:01"
failed with: sed: -e expression #1, char 55: unknown option to `s'

We use a spinlock while we are reading and accessing the destination address for a server.
We need to also use this spinlock to protect when we are modifying this address from
reconn_set_ipaddr().

[ Upstream commit 7717cbec172c3554d470023b4020d5781961187e ]
i2400mu_bus_bm_wait_for_ack() invokes usb_get_urb(), which increases the
refcount of the "notif_urb".
When i2400mu_bus_bm_wait_for_ack() returns, local variable "notif_urb"
becomes invalid, so the refcount should be decreased to keep refcount
balanced.
The issue happens in all paths of i2400mu_bus_bm_wait_for_ack(), which
forget to decrease the refcnt increased by usb_get_urb(), causing a
refcnt leak.
Fix this issue by calling usb_put_urb() before the
i2400mu_bus_bm_wait_for_ack() returns.

[ Upstream commit b87080eab4c1377706c113fc9c0157f19ea8fed1 ]
After successfully running the IPC msgque test once, subsequent runs
result in a test failure:
$ sudo ./run_kselftest.sh
TAP version 13
1..1
# selftests: ipc: msgque
# Failed to get stats for IPC queue with id 0
# Failed to dump queue: -22
# Bail out!
# # Pass 0 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
not ok 1 selftests: ipc: msgque # exit=1
The dump_queue() function loops through the possible message queue index
values using calls to msgctl(kern_id, MSG_STAT, ...) where kern_id
represents the index value. The first time the test is ran, the initial
index value of 0 is valid and the test is able to complete. The index
value of 0 is not valid in subsequent test runs and the loop attempts to
try index values of 1, 2, 3, and so on until a valid index value is
found that corresponds to the message queue created earlier in the test.
The msgctl() syscall returns -1 and sets errno to EINVAL when invalid
index values are used. The test failure is caused by incorrectly
comparing errno to -EINVAL when cycling through possible index values.
Fix invalid test failures on subsequent runs of the msgque test by
correctly comparing errno values to a non-negated EINVAL.

commit c987ff0d3cb37d7fe1ddaa370811dfd9f73643fa upstream.
Where a device driver has set a 64-bit DMA mask to indicate the absence
of addressing limitations, we still need to ensure that we don't
allocate IOVAs beyond the actual input size of the IOMMU. The reported
aperture is the most reliable way we have of inferring that input
address size, so use that to enforce a hard upper limit where available.

commit ae092b5bded24d5dc7dae0e0aef4669c169ce874 upstream.
The phy-mode emac property was only being processed in the phy_id
or fixed-link cases. However if phy-handle was specified instead,
an error message would complain about the lack of phy_id or
fixed-link, and then jump past the of_get_phy_mode(). This would
result in the PHY mode defaulting to MII, regardless of what the
devicetree specified.

Make sure to drop the reference taken by of_parse_phandle() before
returning from dsa_slave_phy_setup().
Note that this also modifies the PHY priority so that any fixed-link
node is only parsed when no phy-handle is given, which is in accordance
with the common scheme for this.

commit deccd16f91f930af8e91ffbbfc839d0ad8da999d upstream.
Commit 5ea94e7686a3 ("phy: add phy_mac_interrupt()") to use with
PHY_IGNORE_INTERRUPT added a cancel_work_sync() into phy_mac_interrupt()
which is allowed to sleep, whereas phy_mac_interrupt() is expected to be
callable from interrupt context.
Now that we have fixed how the PHY state machine treats
PHY_IGNORE_INTERRUPT with respect to state changes, we can just set the
new link state, and queue the PHY state machine for execution so it is
going to read the new link state.
For that to work properly, we need to update phy_change() not to try to
invoke any interrupt callbacks if we have configured the PHY device for
PHY_IGNORE_INTERRUPT, because that PHY device and its driver are not
required to implement those.

Commit 2c7b49212a86 ("phy: fix the use of PHY_IGNORE_INTERRUPT") changed
a hunk in phy_state_machine() in the PHY_RUNNING case which was not
needed. The change essentially makes the PHY library treat PHY devices
with PHY_IGNORE_INTERRUPT to keep polling for the PHY device, even
though the intent is not to do it.
Fix this by reverting that specific hunk, which makes the PHY state
machine wait for state changes, and stay in the PHY_RUNNING state for as
long as needed.
