2018-05-11net: dsa: Add PHYLINK switch operationsFlorian Fainelli3-1/+30
In preparation for adding support for PHYLINK within DSA, define a number of operations that we will need and that switch drivers can start implementing. Proper integration with PHYLINK will follow in subsequent patches. We start selecting PHYLINK (which implies PHYLIB) in net/dsa/Kconfig such that drivers can be guaranteed that this dependency is properly taken care of and can start referencing PHYLINK helper functions without requiring stubs or anything.

2018-05-11net: phy: phylink: Poll link GPIOsRussell King1-0/+16
When using a fixed link with a link GPIO, we need to poll that GPIO to determine link state changes. This is consistent with what fixed_phy.c does. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Ido Schimmel says: ==================== mlxsw: Support VLAN devices in mirroring offloads Petr says: When offloading "tc action mirred mirror", there are several scenarios where VLAN devices can show up, that mlxsw can offload on Spectrum machines. I) A direct mirror to a VLAN device on top of a front-panel port device (commonly referred to as "RSPAN") II) VLAN device in egress path of a packet when resolving a mirror to gretap or ip6gretap netdevice. Specifically in the latter case, the following are the cases that can be offloaded: IIa) VLAN device directly above a physical device. IIb) A VLAN-unaware bridge where the egress device is as in IIa. IIc) VLAN device on top of a VLAN-aware bridge where the egress device is a physical device. This patch set implements all the above cases. First, in patch #1, br_vlan_get_info() is extended to allow bridge master argument. Case I is then implemented in patches #2 and #3, case II in patch #4. Note that handling of VLAN protocol is not included. In case I, mirrored packets may end up being double-tagged, and it might be reasonable for the outer tag to be an 802.1ad. However, the protocol type configuration would have to be put on the same VLAN netdevice that represents normal VLAN traffic, and mlxsw currently ignores this setting in that case. Thus this support was left out and the encapsulation always uses 802.1q protocol. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-05-11tcp: Add mark for TIMEWAIT socketsJon Maxwell5-4/+22
This version has some suggestions by Eric Dumazet: - Use a local variable for the mark in IPv6 instead of ctl_sk to avoid SMP races. - Use the more elegant "IP4_REPLY_MARK(net, skb->mark) ?: sk->sk_mark" statement. - Factorize code as sk_fullsock() check is not necessary. Aidan McGurn from Openwave Mobility systems reported the following bug: "Marked routing is broken on customer deployment. Its effects are large increase in Uplink retransmissions caused by the client never receiving the final ACK to their FINACK - this ACK misses the mark and routes out of the incorrect route." Currently marks are added to sk_buffs for replies when the "fwmark_reflect" sysctl is enabled. But not for TW sockets that had sk->sk_mark set via setsockopt(SO_MARK..). Fix this in IPv4/v6 by adding tw->tw_mark for TIME_WAIT sockets. Copy the the original sk->sk_mark in __inet_twsk_hashdance() to the new tw->tw_mark location. Then progate this so that the skb gets sent with the correct mark. Do the same for resets. Give the "fwmark_reflect" sysctl precedence over sk->sk_mark so that netfilter rules are still honored.

Commit 161d82de1ff8 ("net: bridge: Notify about !added_by_user FDB entries") causes the below oops when bringing up a slave interface, because dsa_port_fdb_add is still scheduled, but with a NULL address. To fix this, keep the dsa_slave_switchdev_event function agnostic of the notified info structure and handle the added_by_user flag in the specific dsa_slave_switchdev_event_work function.

2018-05-10tipc: clean up removal of binding table itemsJon Maloy1-50/+53
In commit be47e41d77fb ("tipc: fix use-after-free in tipc_nametbl_stop") we fixed a problem caused by premature release of service range items. That fix is correct, and solved the problem. However, it doesn't address the root of the problem, which is that we don't lookup the tipc_service -> service_range -> publication items in the correct hierarchical order. In this commit we try to make this right, and as a side effect obtain some code simplification.

2018-05-10net: stmmac: Add support for U32 TC filter using Flexible RX ParserJose Abreu12-3/+636
This adds support for U32 filter by using an HW only feature called Flexible RX Parser. This allow us to match any given packet field with a pattern and accept/reject or even route the packet to a specific DMA channel. Right now we only support acception or rejection of frame and we only support simple rules. Though, the Parser has the flexibility of jumping to specific rules as an if condition so complex rules can be established. This is only supported in GMAC5.10+. The following commands can be used to test this code: 1) Setup an ingress qdisk: # tc qdisc add dev eth0 handle ffff: ingress 2) Setup a filter (e.g. filter by IP): # tc filter add dev eth0 parent ffff: protocol ip u32 match ip \ src 192.168.0.3 skip_sw action drop In every tests performed we always used the "skip_sw" flag to make sure only the RX Parser was involved.
