add9f6f30e soc: rockchip: Fix compile-testing SoC drivers
Similar to commit 7f94b69ece ("ARM: ixp4xx: fix compile-testing soc
drivers").

drivers/soc/rockchip/Kconfig makes plenty of provision for configuring
drivers either for ARCH_ROCKCHIP or for COMPILE_TEST. But
drivers/soc/Makefile pulls the rug out from under us, by refusing to
build anything if we specified COMPILE_TEST but not ARCH_ROCKCHIP.

Currently, I'm not aware of anything that breaks without this patch, but
it certainly makes for confusing builds (CONFIG_ROCKCHIP_PM_DOMAINS=y,
but we didn't actually compile the driver?) and leaves room for future
error (I have pending patches that break confusingly with COMPILE_TEST=y
even though their Kconfig dependencies seem correct [1]).

Defer to drivers/soc/rockchip/{Makefile,Kconfig} to do the right thing.

It's unclear if these are really needed at all, but seemingly their
purpose is only as a write barrier. Use the general macro instead of the
ARM-specific one.

This driver is partially marked for COMPILE_TEST'ing, but it doesn't
build under non-ARM architectures. Fix this up before *really* enabling
it for COMPILE_TEST.

39cb9faa5d rxrpc: Enable IPv6 checksums on transport socket
AF_RXRPC doesn't currently enable IPv6 UDP Tx checksums on the transport
socket it opens and the checksums in the packets it generates end up 0.

It probably should also enable IPv6 UDP Rx checksums and IPv4 UDP
checksums.  The latter only seem to be applied if the socket family is
AF_INET and don't seem to apply if it's AF_INET6.  IPv4 packets from an
IPv6 socket seem to have checksums anyway.

What seems to have happened is that the inet_inv_convert_csum() call didn't
get converted to the appropriate udp_port_cfg parameters - and
udp_sock_create() disables checksums unless explicitly told not too.

Fix this by enabling the three udp_port_cfg checksum options.

2f187bfa6f net: ethernet: ocelot: remove the need for num_stats initializer
There is a desire to share the oclot_stats_layout struct outside of the
current vsc7514 driver. In order to do so, the length of the array needs to
be known at compile time, and defined in the struct ocelot and struct
felix_info.

Since the array is defined in a .c file and would be declared in the header
file via:
extern struct ocelot_stat_layout[];
the size of the array will not be known at compile time to outside modules.

To fix this, remove the need for defining the number of stats at compile
time and allow this number to be determined at initialization.

783d108dd7 tcp: drop skb dst in tcp_rcv_established()
In commit f84af32cbc ("net: ip_queue_rcv_skb() helper")
I dropped the skb dst in tcp_data_queue().

This only dealt with so-called TCP input slow path.

When fast path is taken, tcp_rcv_established() calls
tcp_queue_rcv() while skb still has a dst.

This was mostly fine, because most dsts at this point
are not refcounted (thanks to early demux)

However, TCP packets sent over loopback have refcounted dst.

Then commit 68822bdf76 ("net: generalize skb freeing
deferral to per-cpu lists") came and had the effect
of delaying skb freeing for an arbitrary time.

If during this time the involved netns is dismantled, cleanup_net()
frees the struct net with embedded net->ipv6.ip6_dst_ops.

Then when eventually dst_destroy_rcu() is called,
if (dst->ops->destroy) ... triggers an use-after-free.

It is not clear if ip6_route_net_exit() lacks a rcu_barrier()
as syzbot reported similar issues before the blamed commit.

====================
net: lan966x: remove PHY reset support

Remove the unneeded PHY reset node as well as the driver support for it.

This was already discussed [1] and I expect Microchip to Ack on this
removal. Since there is no user, no breakage is expected.

I'm not sure it this should go through net or net-next and if the patches
should have a Fixes: tag or not. In upstream linux there was never any user
of it, so there is no bug to be fixed. But OTOH if the schema fix isn't
backported, then there might be an older schema version still containing
the reset node. Thoughts?

The patches needed for the GPIO part are just waiting to be picked up by
Linus [2,3]. This patch and the GPIO parts are the last pieces of the
puzzle to get ethernet working on the LAN9668 on upstream linux.

4fdabd509d dt-bindings: net: lan966x: remove PHY reset
The PHY reset was intended to be a phandle for a special PHY reset
driver for the integrated PHYs as well as any external PHYs. It turns
out, that the culprit is how the reset of the switch device is done.
In particular, the switch reset also affects other subsystems like
the GPIO and the SGPIO block and it happens to be the case that the
reset lines of the external PHYs are connected to a common GPIO line.
Thus as soon as the switch issues a reset during probe time, all the
external PHYs will go into reset because all the GPIO lines will
switch to input and the pull-down on that signal will take effect.

So even if there was a special PHY reset driver, it (1) won't fix
the root cause of the problem and (2) it won't fix all the other
consumers of GPIO lines which will also be reset.

It turns out, the Ocelot SoC has the same weird behavior (or the
lack of a dedicated switch reset) and there the problem is already
solved and all the bits and pieces are already there and this PHY
reset property isn't not needed at all.

There are no users of this binding. Just remove it.

fee34dd199 net: dsa: ksz9477: port mirror sniffing limited to one port
This patch limits the sniffing to only one port during the mirror add.
And during the mirror_del it checks for all the ports using the sniff,
if and only if no other ports are referring, sniffing is disabled.
The code is updated based on the review comments of LAN937x port mirror
patch.

52b2abef45 hinic: fix bug of wq out of bound access
If wq has only one page, we need to check wqe rolling over page by
compare end_idx and curr_idx, and then copy wqe to shadow wqe to
avoid out of bound access.
This work has been done in hinic_get_wqe, but missed for hinic_read_wqe.
This patch fixes it, and removes unnecessary MASKED_WQE_IDX().

a3d0562d4d Revert "SUNRPC: attempt AF_LOCAL connect on setup"
This reverts commit 7073ea8799.

We must not try to connect the socket while the transport is under
construction, because the mechanisms to safely tear it down are not in
place. As the code stands, we end up leaking the sockets on a connection
error.

4994d4fa99 Merge branch 'mptcp-path-manager-mode-selection'
Mat Martineau says:

====================
mptcp: Path manager mode selection

MPTCP already has an in-kernel path manager (PM) to add and remove TCP
subflows associated with a given MPTCP connection. This in-kernel PM has
been designed to handle typical server-side use cases, but is not very
flexible or configurable for client devices that may have more
complicated policies to implement.

This patch series from the MPTCP tree is the first step toward adding a
generic-netlink-based API for MPTCP path management, which a privileged
userspace daemon will be able to use to control subflow
establishment. These patches add a per-namespace sysctl to select the
default PM type (in-kernel or userspace) for new MPTCP sockets. New
self-tests confirm expected behavior when userspace PM is selected but
there is no daemon available to handle existing MPTCP PM events.

Subsequent patch series (already staged in the MPTCP tree) will add the
generic netlink path management API.

These tests ensure that the in-kernel path manager is bypassed when
the userspace path manager is configured. Kernel code is still
responsible for ADD_ADDR echo, so also make sure that's working.
