[ Upstream commit 62230715fd2453b3ba948c9d83cfb3ada9169169 ]
Only first fragment has the sport/dport information, not the following ones.
If we want consistent hash for all fragments, we need to ignore ports even for first fragment.
This bug is visible for IPv6 traffic, if incoming fragments do not have a flow label, since skb_get_hash() will give different results for first fragment and following ones.
It is also visible if any routing rule wants dissection and sport or dport.
See commit 5e5d6fed3741 ("ipv6: route: dissect flow in input path if fib rules need it") for details.
[edumazet] rewrote the changelog completely.

[ Upstream commit 16f7eb2b77b55da816c4e207f3f9440a8cafc00a ]
The various types of tunnels running over IPv4 can ask to set the DF bit to do PMTU discovery. However, PMTU discovery is subject to the threshold set by the net.ipv4.route.min_pmtu sysctl, and is also disabled on routes with "mtu lock". In those cases, we shouldn't set the DF bit.
This patch makes setting the DF bit conditional on the route's MTU locking state.
This issue seems to be older than git history.

Preethi reported that PMTU discovery for UDP/raw applications is not working in the presence of VRF when the socket is not bound to a device. The problem is that ip6_sk_update_pmtu does not consider the L3 domain of the skb device if the socket is not bound. Update the function to set oif to the L3 master device if relevant.

[ Upstream commit 33d9a2c72f086cbf1087b2fd2d1a15aa9df14a7f ]
eth_type_trans() assumes initial value for skb->pkt_type is PACKET_HOST.
This is indeed the value right after a fresh skb allocation.
However, it is possible that GRO merged a packet with a different value (like PACKET_OTHERHOST in case macvlan is used), so we need to make sure napi->skb will have pkt_type set back to PACKET_HOST.
Otherwise, valid packets might be dropped by the stack because their pkt_type is not PACKET_HOST.
napi_reuse_skb() was added in commit 96e93eab2033 ("gro: Add internal interfaces for VLAN"), but this bug always has been there.

As rfc7496#section4.5 says about SCTP_PR_SUPPORTED:
This socket option allows the enabling or disabling of the negotiation of PR-SCTP support for future associations. For existing associations, it allows one to query whether or not PR-SCTP support was negotiated on a particular association.
It means only sctp sock's prsctp_enable can be set.
Note that for the limitation of SCTP_{CURRENT|ALL}_ASSOC, we will add it when introducing SCTP_{FUTURE|CURRENT|ALL}_ASSOC for linux sctp in another patchset.
v1->v2: - drop the params.assoc_id check as Neil suggested.

[ Upstream commit 8ebebcba559a1bfbaec7bbda64feb9870b9c58da ]
When writing packets to a descriptor associated with a combined queue, the packets should end up on that queue.
Before this change all packets written to any descriptor associated with a tap interface end up on rx-0, even when the descriptor is associated with a different queue.
The rx traffic can be generated by either of the following. 1. a simple tap program which spins up multiple queues and writes packets to each of the file descriptors 2. tx from a qemu vm with a tap multiqueue netdev
The queue for rx traffic can be observed by either of the following (done on the hypervisor in the qemu case). 1. a simple netmap program which opens and reads from per-queue descriptors 2. configuring RPS and doing per-cpu captures with rxtxcpu
Alternatively, if you printk() the return value of skb_get_rx_queue() just before each instance of netif_receive_skb() in tun.c, you will get 65535 for every skb.
Calling skb_record_rx_queue() to set the rx queue to the queue_index fixes the association between descriptor and rx queue.

[ Upstream commit 7cb6a2a2c72c1ed8f42fb01f1a661281b568dead ]
A timing hazard exists when the network interface is stopped that allows a watchdog timeout to be processed by a separate core in parallel. This creates the potential for the timeout handler to wake the queues while the driver is shutting down, or access registers after their clocks have been removed.
The more common case is that the watchdog timeout will produce a warning message which doesn't lead to a crash. The chances of this are greatly increased by the fact that bcm_sysport_netif_stop stops the transmit queues which can easily precipitate a watchdog time- out because of stale trans_start data in the queues.
This commit corrects the behavior by ensuring that the watchdog timeout is disabled before enterring bcm_sysport_netif_stop. There are currently only two users of the bcm_sysport_netif_stop function: close and suspend.
The close case already handles the issue by exiting the RUNNING state before invoking the driver close service.
The suspend case now performs the netif_device_detach to exit the PRESENT state before the call to bcm_sysport_netif_stop rather than after it.
These behaviors prevent any future scheduling of the driver timeout service during the window. The netif_tx_stop_all_queues function in bcm_sysport_netif_stop is replaced with netif_tx_disable to ensure synchronization with any transmit or timeout threads that may already be executing on other cores.
For symmetry, the netif_device_attach call upon resume is moved to after the call to bcm_sysport_netif_start. Since it wakes the transmit queues it is not necessary to invoke netif_tx_start_all_queues from bcm_sysport_netif_start so it is moved into the driver open service.

Up until commit 7e5fbd1e0700 ("net: mdio-gpio: Convert to use gpiod functions where possible"), the _cansleep variants of the gpio_ API was used. After that commit and the change to gpiod_ API, the _cansleep() was dropped. This then results in WARN_ON() when used with GPIO devices which do sleep. Add back the _cansleep() to avoid this.

Different from processing the addstrm_out request, The receiver handles an addstrm_in request by sending back an addstrm_out request to the sender who will increase its stream's in and incnt later.
Now stream->incnt has been increased since it sent out the addstrm_in request in sctp_send_add_streams(), with the wrong stream->incnt will even cause crash when copying stream info from the old stream's in to the new one's in sctp_process_strreset_addstrm_out().
This patch is to fix it by simply removing the stream->incnt change from sctp_send_add_streams().
