Pull networking fixes from Jakub Kicinski:
"Including fixes from netfilter.

Current release - new code bugs:

- clear msg_get_inq in __sys_recvfrom() and __copy_msghdr_from_user()

- mptcp:
- invoke MP_FAIL response only when needed
- fix shutdown vs fallback race
- consistent map handling on failure

- octeon_ep: use bitwise AND

Previous releases - regressions:

- tipc: move bc link creation back to tipc_node_create, fix NPD

Previous releases - always broken:

- tcp: add a missing nf_reset_ct() in 3WHS handling to prevent socket
buffered skbs from keeping refcount on the conntrack module

- ipv6: take care of disable_policy when restoring routes

- tun: make sure to always disable and unlink NAPI instances

- phy: don't trigger state machine while in suspend

- netfilter: nf_tables: avoid skb access on nf_stolen

- asix: fix "can't send until first packet is send" issue

- usb: asix: do not force pause frames support

- nxp-nci: don't issue a zero length i2c_master_read()

Misc:

- ncsi: allow use of proper "mellanox" DT vendor prefix

- act_api: add a message for user space if any actions were already
flushed before the error was hit"

net: rose: fix UAF bugs caused by timer handler

There are UAF bugs in rose_heartbeat_expiry(), rose_timer_expiry()
and rose_idletimer_expiry(). The root cause is that del_timer()
could not stop the timer handler that is running and the refcount
of sock is not managed properly.

One of the UAF bugs is shown below:

(thread 1) | (thread 2)
| rose_bind
| rose_connect
| rose_start_heartbeat
rose_release | (wait a time)
case ROSE_STATE_0 |
rose_destroy_socket | rose_heartbeat_expiry
rose_stop_heartbeat |
sock_put(sk) | ...
sock_put(sk) // FREE |
| bh_lock_sock(sk) // USE

The sock is deallocated by sock_put() in rose_release() and
then used by bh_lock_sock() in rose_heartbeat_expiry().

Although rose_destroy_socket() calls rose_stop_heartbeat(),
it could not stop the timer that is running.

The KASAN report triggered by POC is shown below:

This patch adds refcount of sock when we use functions
such as rose_start_heartbeat() and so on to start timer,
and decreases the refcount of sock when timer is finished
or deleted by functions such as rose_stop_heartbeat()
and so on. As a result, the UAF bugs could be mitigated.
