2018-05-11tcp: switch pacing timer to softirq based hrtimerEric Dumazet2-45/+26
linux-4.16 got support for softirq based hrtimers. TCP can switch its pacing hrtimer to this variant, since this avoids going through a tasklet and some atomic operations. pacing timer logic looks like other (jiffies based) tcp timers. v2: use hrtimer_try_to_cancel() in tcp_clear_xmit_timers() to correctly release reference on socket if needed.

2018-05-11net: dsa: bcm_sf2: Get rid of PHYLIB functionsFlorian Fainelli1-149/+0
Now that we have converted the bcm_sf2 driver to implement PHYLINK MAC operations, we can remove the PHYLIB callbacks: adjust_link() and fixed_link_update() which are no longer called by DSA. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-05-11net: dsa: Plug in PHYLINK supportFlorian Fainelli3-132/+172
Add support for PHYLINK within the DSA subsystem in order to support more complex devices such as pluggable (SFP) and non-pluggable (SFF) modules, 10G PHYs, and traditional PHYs. Using PHYLINK allows us to drop some amount of complexity we had while probing fixed and non-fixed PHYs using Device Tree. Because PHYLINK separates the Ethernet MAC/port configuration into different stages, we let switch drivers implement those, and for now, we maintain functionality by calling dsa_slave_adjust_link() during phylink_mac_link_{up,down} which provides semantically equivalent steps. Drivers willing to take advantage of PHYLINK should implement the phylink_mac_* operations that DSA wraps. We cannot quite remove the adjust_link() callback just yet, because a number of drivers rely on that for configuring their "CPU" and "DSA" ports, this is done dsa_port_setup_phy_of() and dsa_port_fixed_link_register_of() still. Drivers that utilize fixed links for user-facing ports (e.g: bcm_sf2) will need to implement phylink_mac_ops from now on to preserve functionality, since PHYLINK *does not* create a phy_device instance for fixed links.

2018-05-11net: dsa: mv88e6xxx: add PHYLINK supportRussell King3-0/+125
Add rudimentary phylink support to mv88e6xxx. This allows the driver using user ports with fixed links to keep operating normally. User ports with normal PHYs are not affected since the switch automatically manages their link parameters. User facing ports which use a SFP/SFF with a non-fixed link mode might require a call to phylink_mac_change() to operate properly.

2018-05-11net: dsa: bcm_sf2: Implement phylink_mac_opsFlorian Fainelli1-8/+206
Make the bcm_sf2 driver implement phylink_mac_ops since it needs to support a wide variety of network interfaces: internal & external MDIO PHYs, fixed PHYs, MoCA with MMIO link status. A large amount of what needs to be done already exists under bcm_sf2_sw_adjust_link() so we are essentially breaking this down into the necessary operation for PHYLINK to work: mac_config, mac_link_up, mac_link_down and validate. We can now entirely get rid of most of what fixed_link_update() provided because only the link information is actually necessary. We still have to force DUPLEX_FULL for legacy Device Tree bindings that did not specify that before. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

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.

2018-05-10tcp: 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.

2018-05-10net: dsa: fix added_by_user switchdev notificationVivien Didelot1-5/+7
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.

Avoid potential bugs with fm10k_add_stat_strings and fm10k_add_ethtool_stats by using a macro to calculate the ARRAY_SIZE when passing. This helps ensure that the size is always correct. Note that it assumes we only pass static const fm10k_stat arrays, and that evaluation of the argument won't have side effects.
