2016-02-13bonding: Fix ARP monitor validationJay Vosburgh
The current logic in bond_arp_rcv will accept an incoming ARP for validation if (a) the receiving slave is either "active" (which includes the currently active slave, or the current ARP slave) or, (b) there is a currently active slave, and it has received an ARP since it became active. For case (b), the receiving slave isn't the currently active slave, and is receiving the original broadcast ARP request, not an ARP reply from the target. This logic can fail if there is no currently active slave. In this situation, the ARP probe logic cycles through all slaves, assigning each in turn as the "current_arp_slave" for one arp_interval, then setting that one as "active," and sending an ARP probe from that slave. The current logic expects the ARP reply to arrive on the sending current_arp_slave, however, due to switch FDB updating delays, the reply may be directed to another slave. This can arise if the bonding slaves and switch are working, but the ARP target is not responding. When the ARP target recovers, a condition may result wherein the ARP target host replies faster than the switch can update its forwarding table, causing each ARP reply to be sent to the previous current_arp_slave. This will never pass the logic in bond_arp_rcv, as neither of the above conditions (a) or (b) are met. Some experimentation on a LAN shows ARP reply round trips in the 200 usec range, but my available switches never update their FDB in less than 4000 usec. This patch changes the logic in bond_arp_rcv to additionally accept an ARP reply for validation on any slave if there is a current ARP slave and it sent an ARP probe during the previous arp_interval.

2016-02-10vxlan, gre, geneve: Set a large MTU on ovs-created tunnel devicesDavid Wragg
Prior to 4.3, openvswitch tunnel vports (vxlan, gre and geneve) could transmit vxlan packets of any size, constrained only by the ability to send out the resulting packets. 4.3 introduced netdevs corresponding to tunnel vports. These netdevs have an MTU, which limits the size of a packet that can be successfully encapsulated. The default MTU values are low (1500 or less), which is awkwardly small in the context of physical networks supporting jumbo frames, and leads to a conspicuous change in behaviour for userspace. Instead, set the MTU on openvswitch-created netdevs to be the relevant maximum (i.e. the maximum IP packet size minus any relevant overhead), effectively restoring the behaviour prior to 4.3.

2016-02-10geneve: Relax MTU constraintsDavid Wragg
Allow the MTU of geneve devices to be set to large values, in order to exploit underlying networks with larger frame sizes. GENEVE does not have a fixed encapsulation overhead (an openvswitch rule can add variable length options), so there is no relevant maximum MTU to enforce. A maximum of IP_MAX_MTU is used instead. Encapsulated packets that are too big for the underlying network will get dropped on the floor. Signed-off-by: David Wragg <david@weave.works> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-02-10vxlan: Relax MTU constraintsDavid Wragg
Allow the MTU of vxlan devices without an underlying device to be set to larger values (up to a maximum based on IP packet limits and vxlan overhead). Previously, their MTUs could not be set to higher than the conventional ethernet value of 1500. This is a very arbitrary value in the context of vxlan, and prevented vxlan devices from being able to take advantage of jumbo frames etc. The default MTU remains 1500, for compatibility.

2016-02-09tg3: Fix for tg3 transmit queue 0 timed out when too many gso_segsSiva Reddy Kallam
tg3_tso_bug() can hit a condition where the entire tx ring is not big enough to segment the GSO packet. For example, if MSS is very small, gso_segs can exceed the tx ring size. When we hit the condition, it will cause tx timeout. tg3_tso_bug() is called to handle TSO and DMA hardware bugs. For TSO bugs, if tg3_tso_bug() cannot succeed, we have to drop the packet. For DMA bugs, we can still fall back to linearize the SKB and let the hardware transmit the TSO packet. This patch adds a function tg3_tso_bug_gso_check() to check if there are enough tx descriptors for GSO before calling tg3_tso_bug(). The caller will then handle the error appropriately - drop or lineraize the SKB. v2: Corrected patch description to avoid confusion.

2016-02-05regmap: mmio: Revert to v4.4 endianness handlingMark Brown
Commit 29bb45f25ff3 (regmap-mmio: Use native endianness for read/write) attempted to fix some long standing bugs in the MMIO implementation for big endian systems caused by duplicate byte swapping in both regmap and readl()/writel() which affected MIPS systems as when they are in big endian mode they flip the endianness of all registers in the system, not just the CPU. MIPS systems had worked around this by declaring regmap using IPs as little endian which is inaccurate, unfortunately the issue had not been reported. Sadly the fix makes things worse rather than better. By changing the behaviour to match the documentation it caused behaviour changes for other IPs which broke them and by using the __raw I/O accessors to avoid the endianness swapping in readl()/writel() it removed some memory ordering guarantees and could potentially generate unvirtualisable instructions on some architectures. Unfortunately sorting out all this mess in any half way sensible fashion was far too invasive to go in during an -rc cycle so instead let's go back to the old broken behaviour for v4.5, the better fixes are already queued for v4.6. This does mean that we keep the broken MIPS DTs for another release but that seems the least bad way of handling the situation.

2016-02-05drm/dp/mst: deallocate payload on port destructionMykola Lysenko
This is needed to properly deallocate port payload after downstream branch get unplugged. In order to do this unplugged MST topology should be preserved, to find first alive port on path to unplugged MST topology, and send payload deallocation request to branch device of found port. For this mstb and port kref's are used in reversed order to track when port and branch memory could be freed. Added additional functions to find appropriate mstb as described above.

Previous implementation does not handle case below: boot up one MST branch to DP connector of ASIC. After boot up, hot plug 2nd MST branch to DP output of 1st MST, GUID is not created for 2nd MST branch. When downstream port of 2nd MST branch send upstream request, it fails because 2nd MST branch GUID is not available. New Implementation: only create GUID for MST branch and save it within Branch.

2016-02-05drm/dp/mst: change MST detection schemeMykola Lysenko
1. Get edid for all connected MST displays, not only on logical ports, in the same thread as MST topology detection is done: There are displays that have branches inside w/o logical ports. So in case another SST display connected downstream system can end-up in situation when 3 DOWN requests sent: two for ‘remote i2c read’ and one for ‘enum path resources’, making slots full. 2. Call notification callback in one place in the end of topology discovery/update: This is done to reduce number of events sent to userspace in case complex topology discovery is going, adding multiple number of connectors; 3. Remove notification callback call from short pulse interrupt processing function: This is done in order not to block interrupt processing function, in case any MST request will be made from it. Notification will be send from topology discovery/update work item.
