BCM7xxx internal Gigabit PHY on 28nm process do not need anything special to be done during suspend, remove the suspend callback since it might be harmful rather than useful. While at it, update the comment above bcm7xxx_suspend() to reflect that it applies only to 40nm and 65nm process PHY devices.

The BCM7xxx internal Gigabit PHYs on 28nm process platforms come out reset without any half-duplex or "hub" compatible advertised modes, which was causing auto-negotiation issues coming out of S3 suspend/resume, we just could not establish a link with a half-duplex only link partner. Make sure that the resume function properly re-configures the PHY device to advertise all supported modes.

Fix TCP FRTO logic so that it always notices when snd_una advances, indicating that any RTO after that point will be a new and distinct loss episode. Previously there was a very specific sequence that could cause FRTO to fail to notice a new loss episode had started: (1) RTO timer fires, enter FRTO and retransmit packet 1 in write queue (2) receiver ACKs packet 1 (3) FRTO sends 2 more packets (4) RTO timer fires again (should start a new loss episode) The problem was in step (3) above, where tcp_process_loss() returned early (in the spot marked "Step 2.b"), so that it never got to the logic to clear icsk_retransmits. Thus icsk_retransmits stayed non-zero. Thus in step (4) tcp_enter_loss() would see the non-zero icsk_retransmits, decide that this RTO is not a new episode, and decide not to cut ssthresh and remember the current cwnd and ssthresh for undo. There were two main consequences to the bug that we have observed. First, ssthresh was not decreased in step (4). Second, when there was a series of such FRTO (1-4) sequences that happened to be followed by an FRTO undo, we would restore the cwnd and ssthresh from before the entire series started (instead of the cwnd and ssthresh from before the most recent RTO). This could result in cwnd and ssthresh being restored to values much bigger than the proper values.

由 Hannes Frederic Sowa 提交于
tcp_tw_recycle heavily relies on tcp timestamps to build a per-host ordering of incoming connections and teardowns without the need to hold state on a specific quadruple for TCP_TIMEWAIT_LEN, but only for the last measured RTO. To do so, we keep the last seen timestamp in a per-host indexed data structure and verify if the incoming timestamp in a connection request is strictly greater than the saved one during last connection teardown. Thus we can verify later on that no old data packets will be accepted by the new connection. During moving a socket to time-wait state we already verify if timestamps where seen on a connection. Only if that was the case we let the time-wait socket expire after the RTO, otherwise normal TCP_TIMEWAIT_LEN will be used. But we don't verify this on incoming SYN packets. If a connection teardown was less than TCP_PAWS_MSL seconds in the past we cannot guarantee to not accept data packets from an old connection if no timestamps are present. We should drop this SYN packet. This patch closes this loophole. Please note, this patch does not make tcp_tw_recycle in any way more usable but only adds another safety check: Sporadic drops of SYN packets because of reordering in the network or in the socket backlog queues can happen. Users behing NAT trying to connect to a tcp_tw_recycle enabled server can get caught in blackholes and their connection requests may regullary get dropped because hosts behind an address translator don't have synchronized tcp timestamp clocks. tcp_tw_recycle cannot work if peers don't have tcp timestamps enabled. In general, use of tcp_tw_recycle is disadvised.

As of 4fddbf5d ("sit: strictly restrict incoming traffic to tunnel link device"), when looking up a tunnel, tunnel's underlying interface (t->parms.link) is verified to match incoming traffic's ingress device. However the comparison was incorrectly based on skb->dev->iflink. Instead, dev->ifindex should be used, which correctly represents the interface from which the IP stack hands the ipip6 packets. This allows setting up sit tunnels bound to vlan interfaces (otherwise incoming ipip6 traffic on the vlan interface was dropped due to ipip6_tunnel_lookup match failure).

xgene_enet_get_ring_size() returns a negative value in case of an error, but its only caller in xgene_enet_create_desc_ring() currently uses the return value directly as u32. Instead, check for a negative value first and error out in case. Also move the call to xgene_enet_get_ring_size() before devm_kzalloc() so we don't need to free anything in the error path. This fixes the following issue reported by the Coverity Scanner: ** CID 1231336: Improper use of negative value (NEGATIVE_RETURNS) /drivers/net/ethernet/apm/xgene/xgene_enet_main.c: 596 in xgene_enet_create_desc_ring() Signed-off-by: NTobias Klauser <tklauser@distanz.ch> Signed-off-by: NDavid S.

Benjamin Herrenschmidt pointed out that I further missed modifying update_vsyscall after the wall_to_mono value was changed to a timespec64. This causes issues on powerpc32, which expects a 32bit timespec. This patch fixes the problem by properly converting from a timespec64 to a timespec before passing the value on to the arch-specific vsyscall logic.

Pull more powerpc updates from Ben Herrenschmidt: "Here are some more powerpc bits for 3.17, essentially fixes. The biggest series, also aimed at -stable, is from Aneesh and is the result of weeks and weeks of debugging to find out why the heck or THP implementation was occasionally triggering multi-hit errors in our level 1 TLB. It ended up being a combination of issues including subtleties as to how we should invalidate those special 'MPSS' pages we use to allow the use of 16M pages inside 4K/64K "base page size" segments (you really have to love our MMU !) Another interesting one in the "OMG" category is the series from Michael adding memory barriers to spin_is_locked(). That's also the result of many days of debugging to figure out why the semaphore code would occasionally crash in ways that made no sense. It ended up being some creative lock stacking that was defeated by the fact that our locks allow a load inside the locked section to be re-ordered with the load of the lock value itself (I'm still of two mind about whether to kill that once and for all by putting a heavier barrier back into our lock implementation...).
