This new config switch enables the ingress filtering infrastructure that is controlled through the ingress_needed static key. This prepares the introduction of the Netfilter ingress hook that resides under this unique static key. Note that CONFIG_SCH_INGRESS automatically selects this, that should be no problem since this also depends on CONFIG_NET_CLS_ACT.

They can use BPF_SYSCALL to allow loading from userspace or select BPF to use it directly from kernel in NET-less configs. - in 3.18 programs cannot be attached to events yet, so don't force it on - when the rest of eBPF infra is there in 3.19+, it's still useful to switch it off to minimize kernel size bloat-o-meter on x64 shows: add/remove: 0/60 grow/shrink: 0/2 up/down: 0/-15601 (-15601) tested with many different config combinations.

Jesper reported that br_netfilter always registers the hooks since this is part of the bridge core. This harms performance for people that don't need this. This patch modularizes br_netfilter so it can be rmmod'ed, thus, the hooks can be unregistered. I think the bridge netfilter should have been a separated module since the beginning, Patrick agreed on that. Note that this is breaking compatibility for users that expect that bridge netfilter is going to be available after explicitly 'modprobe bridge' or via automatic load through brctl. However, the damage can be easily undone by modprobing br_netfilter. The bridge core also spots a message to provide a clue to people that didn't notice that this has been deprecated. On top of that, the plan is that nftables will not rely on this software layer, but integrate the connection tracking into the bridge layer to enable stateful filtering and NAT, which is was bridge netfilter users seem to require. This patch still keeps the fake_dst_ops in the bridge core, since this is required by when the bridge port is initialized. So we can safely modprobe/rmmod br_netfilter anytime.

This patch moves generic code which is used by bluetooth and ieee802154 6lowpan to a new net/6lowpan directory. This directory contains generic 6LoWPAN code which is shared between bluetooth and ieee802154 MAC-Layer. This is the IPHC - "IPv6 Header Compression" format at the moment. Which is described by RFC 6282 [0]. The BLTE 6LoWPAN draft describes that the IPHC is the same format like IEEE 802.15.4, see [1]. Futuremore we can put more code into this directory which is shared between BLTE and IEEE 802.15.4 6LoWPAN like RFC 6775 or the routing protocol RPL RFC 6550.

This commit fixes a build error reported by Fengguang, that is triggered when CONFIG_NETWORK_PHY_TIMESTAMPING is not set: ERROR: "ptp_classify_raw" [drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe.ko] undefined! The fix is to introduce its own file for the PTP BPF classifier, so that PTP_1588_CLOCK and/or NETWORK_PHY_TIMESTAMPING can select it independently from each other. IXP4xx driver on ARM needs to select it as well since it does not seem to select PTP_1588_CLOCK or similar that would pull it in automatically. This also allows for hiding all of the internals of the BPF PTP program inside that file, and only exporting relevant API bits to drivers. This patch also adds a kdoc documentation of ptp_classify_raw() API to make it clear that it can return PTP_CLASS_* defines. Also, the BPF program has been translated into bpf_asm code, so that it can be more easily read and altered (extensively documented in [1]). In the kernel tree under tools/net/ we have bpf_asm and bpf_dbg tools, so the commented program can simply be translated via `./bpf_asm -c prog` where prog is a file that contains the commented code. This makes it easily readable/verifiable and when there's a need to change something, jump offsets etc do not need to be replaced manually which can be very error prone. Instead, a newly translated version via bpf_asm can simply replace the old code. I have checked opcode diffs before/after and it's the very same filter.

net_prio is the only cgroup which is allowed to be built as a module. The savings from allowing one controller to be built as a module are tiny especially given that cgroup module support itself adds quite a bit of complexity. Given that none of other controllers has much chance of being made a module and that we're unlikely to add new modular controllers, the added complexity is simply not justifiable. As a first step to drop cgroup module support, this patch changes the config option to bool from tristate and drops module related code from it. Also, while an earlier commit fe1217c4 ("net: net_cls: move cgroupfs classid handling into core") dropped module support from net_cls cgroup, it retained a call to cgroup_load_subsys(), which is noop for built-in controllers. Drop it along with init_netclassid_cgroup(). v2: Removed modular version of task_netprioidx() in include/net/netprio_cgroup.h as suggested by Li Zefan. v3: Rebased on top of fe1217c4 ("net: net_cls: move cgroupfs classid handling into core"). net_cls cgroup part is mostly dropped except for removal of init_netclassid_cgroup().

Zefan Li requested [1] to perform the following cleanup/refactoring: - Split cgroupfs classid handling into net core to better express a possible more generic use. - Disable module support for cgroupfs bits as the majority of other cgroupfs subsystems do not have that, and seems to be not wished from cgroup side. Zefan probably might want to follow-up for netprio later on. - By this, code can be further reduced which previously took care of functionality built when compiled as module. cgroupfs bits are being placed under net/core/netclassid_cgroup.c, so that we are consistent with {netclassid,netprio}_cgroup naming that is under net/core/ as suggested by Zefan. No change in functionality, but only code refactoring that is being done here.

High-availability Seamless Redundancy ("HSR") provides instant failover redundancy for Ethernet networks. It requires a special network topology where all nodes are connected in a ring (each node having two physical network interfaces). It is suited for applications that demand high availability and very short reaction time. HSR acts on the Ethernet layer, using a registered Ethernet protocol type to send special HSR frames in both directions over the ring. The driver creates virtual network interfaces that can be used just like any ordinary Linux network interface, for IP/TCP/UDP traffic etc. All nodes in the network ring must be HSR capable. This code is a "best effort" to comply with the HSR standard as described in IEC 62439-3:2010 (HSRv0). Signed-off-by: NArvid Brodin <arvid.brodin@xdin.com> Signed-off-by: NDavid S.

In the case where a non-MPLS packet is received and an MPLS stack is added it may well be the case that the original skb is GSO but the NIC used for transmit does not support GSO of MPLS packets. The aim of this code is to provide GSO in software for MPLS packets whose skbs are GSO. SKB Usage: When an implementation adds an MPLS stack to a non-MPLS packet it should do the following to skb metadata: * Set skb->inner_protocol to the old non-MPLS ethertype of the packet. skb->inner_protocol is added by this patch. * Set skb->protocol to the new MPLS ethertype of the packet. * Set skb->network_header to correspond to the end of the L3 header, including the MPLS label stack. I have posted a patch, "[PATCH v3.29] datapath: Add basic MPLS support to kernel" which adds MPLS support to the kernel datapath of Open vSwtich. That patch sets the above requirements in datapath/actions.c:push_mpls() and was used to exercise this code. The datapath patch is against the Open vSwtich tree but it is intended that it be added to the Open vSwtich code present in the mainline Linux kernel at some point. Features: I believe that the approach that I have taken is at least partially consistent with the handling of other protocols. Jesse, I understand that you have some ideas here. I am more than happy to change my implementation. This patch adds dev->mpls_features which may be used by devices to advertise features supported for MPLS packets. A new NETIF_F_MPLS_GSO feature is added for devices which support hardware MPLS GSO offload. Currently no devices support this and MPLS GSO always falls back to software. Alternate Implementation: One possible alternate implementation is to teach netif_skb_features() and skb_network_protocol() about MPLS, in a similar way to their understanding of VLANs. I believe this would avoid the need for net/mpls/mpls_gso.c and in particular the calls to __skb_push() and __skb_push() in mpls_gso_segment(). I have decided on the implementation in this patch as it should not introduce any overhead in the case where mpls_gso is not compiled into the kernel or inserted as a module. MPLS GSO suggested by Jesse Gross. Based in part on "v4 GRE: Add TCP segmentation offload for GRE" by Pravin B Shelar.

A cpu executing the network receive path sheds packets when its input queue grows to netdev_max_backlog. A single high rate flow (such as a spoofed source DoS) can exceed a single cpu processing rate and will degrade throughput of other flows hashed onto the same cpu. This patch adds a more fine grained hashtable. If the netdev backlog is above a threshold, IRQ cpus track the ratio of total traffic of each flow (using 4096 buckets, configurable). The ratio is measured by counting the number of packets per flow over the last 256 packets from the source cpu. Any flow that occupies a large fraction of this (set at 50%) will see packet drop while above the threshold. Tested: Setup is a muli-threaded UDP echo server with network rx IRQ on cpu0, kernel receive (RPS) on cpu0 and application threads on cpus 2--7 each handling 20k req/s. Throughput halves when hit with a 400 kpps antagonist storm. With this patch applied, antagonist overload is dropped and the server processes its complete load. The patch is effective when kernel receive processing is the bottleneck. The above RPS scenario is a extreme, but the same is reached with RFS and sufficient kernel processing (iptables, packet socket tap, ..).

VM Sockets allows communication between virtual machines and the hypervisor. User level applications both in a virtual machine and on the host can use the VM Sockets API, which facilitates fast and efficient communication between guest virtual machines and their host. A socket address family, designed to be compatible with UDP and TCP at the interface level, is provided. Today, VM Sockets is used by various VMware Tools components inside the guest for zero-config, network-less access to VMware host services. In addition to this, VMware's users are using VM Sockets for various applications, where network access of the virtual machine is restricted or non-existent. Examples of this are VMs communicating with device proxies for proprietary hardware running as host applications and automated testing of applications running within virtual machines. The VMware VM Sockets are similar to other socket types, like Berkeley UNIX socket interface. The VM Sockets module supports both connection-oriented stream sockets like TCP, and connectionless datagram sockets like UDP. The VM Sockets protocol family is defined as "AF_VSOCK" and the socket operations split for SOCK_DGRAM and SOCK_STREAM. For additional information about the use of VM Sockets, please refer to the VM Sockets Programming Guide available at: https://www.vmware.com/support/developer/vmci-sdk/Signed-off-by: NGeorge Zhang <georgezhang@vmware.com> Signed-off-by: NDmitry Torokhov <dtor@vmware.com> Signed-off-by: NAndy king <acking@vmware.com> Signed-off-by: NDavid S.

The original suggestion to delete wanrouter started earlier with the mainline commit f0d1b3c2 ("net/wanrouter: Deprecate and schedule for removal") in May 2012. More importantly, Dan Carpenter found[1] that the driver had a fundamental breakage introduced back in 2008, with commit 7be6065b ("netdevice wanrouter: Convert directly reference of netdev->priv"). So we know with certainty that the code hasn't been used by anyone willing to at least take the effort to send an e-mail report of breakage for at least 4 years. This commit does a decouple of the wanrouter subsystem, by going after the Makefile/Kconfig and similar files, so that these mainline files that we are keeping do not have the big wanrouter file/driver deletion commit tied into their history. Once this commit is in place, we then can remove the obsolete cyclomx drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

Stephen Rothwell says: ==================== After merging the final tree, today's linux-next build (powerpc ppc44x_defconfig) failed like this: net/built-in.o: In function `tcp_fastopen_ctx_free': tcp_fastopen.c:(.text+0x5cc5c): undefined reference to `crypto_destroy_tfm' net/built-in.o: In function `tcp_fastopen_reset_cipher': (.text+0x5cccc): undefined reference to `crypto_alloc_base' net/built-in.o: In function `tcp_fastopen_reset_cipher': (.text+0x5cd6c): undefined reference to `crypto_destroy_tfm' Presumably caused by commit 10467163 ("tcp: TCP Fast Open Server - header & support functions") from the net-next tree. I assume that some dependency on the CRYPTO infrastructure is missing. I have reverted commit 1bed966c ("Merge branch 'tcp_fastopen_server'") for today. ==================== Reported-by: NStephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: NDavid S.

There is no point having the NET dependency on the select target, as it forces all users to depend on NET to tell they support BPF_JIT. Move the config option to the bottom of the file - this could be a nice place also for future "selectable" config symbols. Fix up all users to drop the dependency on NET now that it is not required to supress warnings for non-NET builds.

More spring cleaning! The ancient Econet protocol should go. Most of the bug fixes in recent years have been fixing security vulnerabilities. The hardware hasn't been made since the 90s, it is only interesting as an archeological curiosity. For the truly curious, or insomniac, go read up on it. http://en.wikipedia.org/wiki/EconetSigned-off-by: NStephen Hemminger <shemminger@vyatta.com> Signed-off-by: NDavid S.

When I first wrote drop monitor I wrote it to just build monolithically. There is no reason it can't be built modularly as well, so lets give it that flexibiity. I've tested this by building it as both a module and monolithically, and it seems to work quite well Change notes: v2) * fixed for_each_present_cpu loops to be more correct as per Eric D. * Converted exit path failures to BUG_ON as per Ben H. v3) * Converted del_timer to del_timer_sync to close race noted by Ben H.

Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules. See http://openvswitch.org for more information and userspace utilities. Signed-off-by: NJesse Gross <jesse@nicira.com>

Networking stack support for byte queue limits, uses dynamic queue limits library. Byte queue limits are maintained per transmit queue, and a dql structure has been added to netdev_queue structure for this purpose. Configuration of bql is in the tx-<n> sysfs directory for the queue under the byte_queue_limits directory. Configuration includes: limit_min, bql minimum limit limit_max, bql maximum limit hold_time, bql slack hold time Also under the directory are: limit, current byte limit inflight, current number of bytes on the queue Signed-off-by: NTom Herbert <therbert@google.com> Acked-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

This patch adds in the infrastructure code to create the network priority cgroup. The cgroup, in addition to the standard processes file creates two control files: 1) prioidx - This is a read-only file that exports the index of this cgroup. This is a value that is both arbitrary and unique to a cgroup in this subsystem, and is used to index the per-device priority map 2) priomap - This is a writeable file. On read it reports a table of 2-tuples <name:priority> where name is the name of a network interface and priority is indicates the priority assigned to frames egresessing on the named interface and originating from a pid in this cgroup This cgroup allows for skb priority to be set prior to a root qdisc getting selected. This is benenficial for DCB enabled systems, in that it allows for any application to use dcb configured priorities so without application modification Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Signed-off-by: NJohn Fastabend <john.r.fastabend@intel.com> CC: Robert Love <robert.w.love@intel.com> CC: "David S.
