mptcp: Connection and accounting fixes
Here are some miscellaneous fixes for MPTCP:
Patch 1 modifies an MPTCP hash so it doesn't depend on one of skb->dev
and skb->sk being non-NULL.
Patch 2 removes an extra destructor call when rejecting a join due to
port mismatch.
Patches 3 and 5 more cleanly handle error conditions with MP_JOIN and
syncookies, and update a related self test.
Patch 4 makes sure packets that trigger a subflow TCP reset during MPTCP
option header processing are correctly dropped.
Patch 6 addresses a rmem accounting issue that could keep packets in
subflow receive buffers longer than necessary, delaying MPTCP-level
ACKs.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
After commit 879526030c ("mptcp: protect the rx path with
the msk socket spinlock") the rmem currently used by a given
msk is really sk_rmem_alloc - rmem_released.
The safety check in mptcp_data_ready() does not take the above
in due account, as a result legit incoming data is kept in
subflow receive queue with no reason, delaying or blocking
MPTCP-level ack generation.
This change addresses the issue introducing a new helper to fetch
the rmem memory and using it as needed. Additionally add a MIB
counter for the exceptional event described above - the peer is
misbehaving.
Finally, introduce the required annotation when rmem_released is
updated.

Lots of "TCP: tcp_fin: Impossible, sk->sk_state=7" in client side
when doing stress testing using wrk and webfsd.
There are at least two cases may trigger this warning:
1.mptcp is in syncookie, and server recv MP_JOIN SYN request,
in subflow_check_req(), the mptcp_can_accept_new_subflow()
return false, so subflow_init_req_cookie_join_save() isn't
called, i.e. not store the data present in the MP_JOIN syn
request and the random nonce in hash table - join_entries[],
but still send synack. When recv 3rd-ack,
mptcp_token_join_cookie_init_state() will return false, and
3rd-ack is dropped, then if mptcp conn is closed by client,
client will send a DATA_FIN and a MPTCP FIN, the DATA_FIN
doesn't have MP_CAPABLE or MP_JOIN,
so mptcp_subflow_init_cookie_req() will return 0, and pass
the cookie check, MP_JOIN request is fallback to normal TCP.
Server will send a TCP FIN if closed, in client side,
when process TCP FIN, it will do reset, the code path is:
tcp_data_queue()->mptcp_incoming_options()
->check_fully_established()->mptcp_subflow_reset().
mptcp_subflow_reset() will set sock state to TCP_CLOSE,
so tcp_fin will hit TCP_CLOSE, and print the warning.
2.mptcp is in syncookie, and server recv 3rd-ack, in
mptcp_subflow_init_cookie_req(), mptcp_can_accept_new_subflow()
return false, and subflow_req->mp_join is not set to 1,
so in subflow_syn_recv_sock() will not reset the MP_JOIN
subflow, but fallback to normal TCP, and then the same thing
happens when server will send a TCP FIN if closed.
For case1, subflow_check_req() return -EPERM,
then tcp_conn_request() will drop MP_JOIN SYN.
For case2, let subflow_syn_recv_sock() call
mptcp_can_accept_new_subflow(), and do fatal fallback, send reset.

In subflow_check_req(), if subflow sport is mismatch, will put msk,
destroy token, and destruct req, then return -EPERM, which can be
done by subflow_req_destructor() via:
tcp_conn_request()
|--__reqsk_free()
|--subflow_req_destructor()
So we should remove these redundant code, otherwise will call
tcp_v4_reqsk_destructor() twice, and may double free

commit 03623b4b04 ("rtc: pcf2127: add tamper detection support")
added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:
[ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option)
...
[ 121.238087] [<00000000c4d69393>] irq_default_primary_handler threaded [<000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127]
[ 121.248971] Disabling IRQ #78
Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.
However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

The offset variable is checked by at91_rtc_readalarm(), but this check
is unnecessary because the previous check knew that the value of this
variable was not 0.
This removes that unnecessary offset variable checks.

skb_tunnel_info() returns pointer of lwtstate->data as ip_tunnel_info
type without validation. lwtstate->data can have various types such as
mpls_iptunnel_encap, etc and these are not compatible.
So skb_tunnel_info() should validate before returning that pointer.
Splat looks like:

Commit 28e104d002 ("net: ip_tunnel: fix mtu calculation") removed
dev->hard_header_len subtraction when calculate MTU for tunnel devices
as there is an overhead for device that has header_ops.
But there are ETHER tunnel devices, like gre_tap or erspan, which don't
have header_ops but set dev->hard_header_len during setup. This makes
pkts greater than (MTU - ETH_HLEN) could not be xmited. Fix it by
subtracting the ETHER tunnel devices' dev->hard_header_len for MTU
calculation.

Some socket buffers allocated in the fclone cache (in __alloc_skb) can
end-up in the following path[1]:
napi_skb_finish
__kfree_skb_defer
napi_skb_cache_put
The issue is napi_skb_cache_put is not fclone friendly and will put
those skbuff in the skb cache to be reused later, although this cache
only expects skbuff allocated from skbuff_head_cache. When this happens
the skbuff is eventually freed using the wrong origin cache, and we can
see traces similar to:
[ 1223.947534] cache_from_obj: Wrong slab cache. skbuff_head_cache but object is from skbuff_fclone_cache
[ 1223.948895] WARNING: CPU: 3 PID: 0 at mm/slab.h:442 kmem_cache_free+0x251/0x3e0

[ 1223.953060] RIP: 0010:kmem_cache_free+0x251/0x3e0
Leading sometimes to other memory related issues.
Fix this by using __kfree_skb for fclone skbuff, similar to what is done
the other place __kfree_skb_defer is called.
[1] At least in setups using veth pairs and tunnels. Building a kernel
with KASAN we can for example see packets allocated in
sk_stream_alloc_skb hit the above path and later the issue arises
when the skbuff is reused.

sk_wmem_schedule makes sure that sk_forward_alloc has enough
bytes for charging that is going to be done by sk_mem_charge.
In the transmit zerocopy path, there is sk_mem_charge but there was
no call to sk_wmem_schedule. This change adds that call.
Without this call to sk_wmem_schedule, sk_forward_alloc can go
negetive which is a bug because sk_forward_alloc is a per-socket
space that has been forward charged so this can't be negative.

priv is netdev private data and it cannot be
used after free_netdev() call. Using priv after free_netdev()
can cause UAF bug. Fix it by moving free_netdev() at the end of the
function.

In case of netdev registration failure the code path will
jump to init_fail label:
init_fail:
netdev_err(ndev, "init failed\n");
moxart_mac_free_memory(ndev);
irq_map_fail:
free_netdev(ndev);
return ret;
So, there is no need to call free_netdev() before jumping
to error handling path, since it can cause UAF or double-free
bug.
