'struct timeval' uses 32-bit representation for seconds which will overflow in year 2038 and beyond. mISDN/clock.c needs to compute and store elapsed time in intervals of 125 microseconds. This patch replaces the usage of 'struct timeval' with 64-bit ktime_t which is y2038 safe. The patch also replaces do_gettimeofday() (wall-clock time) with ktime_get() (monotonic time) since we only care about elapsed time here. Signed-off-by:

Jesse Gross says: ==================== Tunneling fixes This series fixes a problem that was reported where encapsulated packets do not have their encapsulation offload markers stripped off when being decapsulated. This causes a significant performance drop if the packets are later retransmitted. Fixing this revealed two other bugs which are also addressed as prerequisites: * GRO can aggregate packets for multiple layers of encapsulation which the stack cannot properly handle. * IPIP packets which are combined by GRO are not marked properly with their GSO type. Note that this is based off the net-next tree as the current target for bug fixes. v2: No code changes, just additional information in commit messages and a new cover letter. ==================== Signed-off-by: -

If a packet is either locally encapsulated or processed through GRO it is marked with the offloads that it requires. However, when it is decapsulated these tunnel offload indications are not removed. This means that if we receive an encapsulated TCP packet, aggregate it with GRO, decapsulate, and retransmit the resulting frame on a NIC that does not support encapsulation, we won't be able to take advantage of hardware offloads even though it is just a simple TCP packet at this point. This fixes the problem by stripping off encapsulation offload indications when packets are decapsulated. The performance impacts of this bug are significant. In a test where a Geneve encapsulated TCP stream is sent to a hypervisor, GRO'ed, decapsulated, and bridged to a VM performance is improved by 60% (5Gbps->8Gbps) as a result of avoiding unnecessary segmentation at the VM tap interface.

When drivers express support for TSO of encapsulated packets, they only mean that they can do it for one layer of encapsulation. Supporting additional levels would mean updating, at a minimum, more IP length fields and they are unaware of this. No encapsulation device expresses support for handling offloaded encapsulated packets, so we won't generate these types of frames in the transmit path. However, GRO doesn't have a check for multiple levels of encapsulation and will attempt to build them. UDP tunnel GRO actually does prevent this situation but it only handles multiple UDP tunnels stacked on top of each other. This generalizes that solution to prevent any kind of tunnel stacking that would cause problems. Fixes: bf5a755f ("net-gre-gro: Add GRE support to the GRO stack") Signed-off-by:

ipip encapsulated packets can be merged together by GRO but the result does not have the proper GSO type set or even marked as being encapsulated at all. Later retransmission of these packets will likely fail if the device does not support ipip offloads. This is similar to the issue resolved in IPv6 sit in feec0cb3 ("ipv6: gro: support sit protocol").

If the user supply a different fragmentation point or if there is a network header that cause it to not be aligned, force it to be aligned. Fragmentation point at a value that is not aligned is not optimal. It causes extra padding to be used and has just no pros. v2: - Make use of the new WORD_TRUNC macro Signed-off-by:

SCTP is a protocol that is aligned to a word (4 bytes). Thus using bare MTU can sometimes return values that are not aligned, like for loopback, which is 65536 but ipv4_mtu() limits that to 65535. This mis-alignment will cause the last non-aligned bytes to never be used and can cause issues with congestion control. So it's better to just consider a lower MTU and keep congestion control calcs saner as they are based on PMTU. Same applies to icmp frag needed messages, which is also fixed by this patch. One other effect of this is the inability to send MTU-sized packet without queueing or fragmentation and without hitting Nagle. As the check performed at sctp_packet_can_append_data(): if (chunk->skb->len + q->out_qlen >= transport->pathmtu - packet->overhead) /* Enough data queued to fill a packet */ return SCTP_XMIT_OK; with the above example of MTU, if there are no other messages queued, one cannot send a packet that just fits one packet (65532 bytes) and without causing DATA chunk fragmentation or a delay. v2: - Added WORD_TRUNC macro Signed-off-by:

Currently, if a chunk is scheduled to be sent through a transport that is currently unconfirmed, it will be leaked as it is dequeued from outq and is not re-queued nor freed. As I'm not aware of any situation that may lead to this situation, I'm fixing this by freeing the chunk and also logging a trace so that we can fix the other bug if it ever happens. Signed-off-by:

The SACK can be lost pretty much elsewhere, but if its allocation fail, we know we are not sending it, so it is better to revert a_rwnd to its previous value as this may give it a chance to issue a window update later. Signed-off-by:

Daniel Borkmann says: ==================== flowi6_tos fixes This set is a follow-up to address Jiri's recent feedback [1] on the flowi6_tos issue, that it is not used for IPv6 route lookups. The three patches fix all current users of flowi6_tos and remove the define to avoid any future confusion on this. Tested the vxlan and geneve ones with IPv6 routing rules. For details, please see individual patches. [ As fixes are currently applied against net-next tree, I've rebased it against that. ] Thanks!

flowi6_tos of struct flowi6 is unused in IPv6, therefore dumping tos on that tracepoint will also give incorrect information wrt traffic class. If we want to fix it, we need to extract it via ip6_tclass(flp->flowlabel). While for the same test case I get a count of 0 non-zero tos values before the change, they now start to show up after the change: # ./perf record -e fib6:fib6_table_lookup -a sleep 10 # ./perf script | grep -v "tos 0" | wc -l 60 Since there's no user in the kernel tree anymore of flowi6_tos, remove the define to avoid any future confusion on this.

The struct flowi6's flowi6_tos is not used in IPv6 route lookup, the traffic class information is handled in the flowi6's flowlabel member instead. For example, for policy routing, fib6_rule_match() uses ip6_tclass() that is applied on the flowlabel for matching on tclass, which would currently not work as expected.

Daniel Borkmann authored
Jiri mentioned that flowi6_tos of struct flowi6 is never used/read anywhere. In fact, rest of the kernel uses the flowi6's flowlabel, where the traffic class _and_ the flowlabel (aka flowinfo) is encoded. For example, for policy routing, fib6_rule_match() uses ip6_tclass() that is applied on the flowlabel member for matching on tclass. Similar fix is needed for geneve, where flowi6_tos is set as well. Installing a v6 blackhole rule that f.e. matches on tos is now working with vxlan. Fixes: 1400615d ("vxlan: allow setting ipv6 traffic class") Reported-by:

Pull cgroup updates from Tejun Heo: "cgroup changes for v4.6-rc1. No userland visible behavior changes in this pull request. I'll send out a separate pull request for the addition of cgroup namespace support. - The biggest change is the revamping of cgroup core task migration and controller handling logic. There are quite a few places where controllers and tasks are manipulated. Previously, many of those places implemented custom operations for each specific use case assuming specific starting conditions. While this worked, it makes the code fragile and difficult to follow. The bulk of this pull request restructures these operations so that most related operations are performed through common helpers which implement recursive (subtrees are always processed consistently) and idempotent (they make cgroup hierarchy converge to the target state rather than performing operations assuming specific starting conditions). This makes the code a lot easier to understand, verify and extend. - Implicit controller support is added. This is primarily for using perf_event on the v2 hierarchy so that perf can match cgroup v2 path without requiring the user to do anything special. The kernel portion of perf_event changes is acked but userland changes are still pending review. - cgroup_no_v1= boot parameter added to ease testing cgroup v2 in certain environments. - There is a regression introduced during v4.4 devel cycle where attempts to migrate zombie tasks can mess up internal object management.

bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73 ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem. Given that RTNL is not always held, we need to use bond_for_each_slave_rcu(). Fixes: 5f0c5f73 ("bonding: make global bonding stats more reliable") Signed-off-by:

Add per-net sysctl tunables to set the size of sndbuf and rcvbuf on the kernel tcp socket. The tunables are added at /proc/sys/net/rds/tcp/rds_tcp_sndbuf and /proc/sys/net/rds/tcp/rds_tcp_rcvbuf. These values must be set before accept() or connect(), and there may be an arbitrary number of existing rds-tcp sockets when the tunable is modified. To make sure that all connections in the netns pick up the same value for the tunable, we reset existing rds-tcp connections in the netns, so that they can reconnect with the new parameters.

Convert the dma transfers to be dmaengine based, now pxa has a dmaengine slave driver. This makes this driver a bit more PXA agnostic. The driver was only compile tested. The risk is quite small as no current PXA platform I'm aware of is using smc911x driver. Signed-off-by:
