2018-10-16FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapterMaciej W. Rozycki2-0/+59
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment Corporation's first-generation FDDI network interface adapter, made for TURBOchannel and based on a discrete version of what eventually became Motorola's widely used CAMEL chipset. The CAMEL chipset is present for example in the DEC FDDIcontroller TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support with the `defxx' driver, however the host bus interface logic and the firmware API are different in the DEFZA and hence a separate driver is required. There isn't much to say about the driver except that it works, but there is one peculiarity to mention. The adapter implements two Tx/Rx queue pairs. Of these one pair is the usual network Tx/Rx queue pair, in this case used by the adapter to exchange frames with the ring, via the RMC (Ring Memory Controller) chip. The Tx queue is handled directly by the RMC chip and resides in onboard packet memory. The Rx queue is maintained via DMA in host memory by adapter's firmware copying received data stored by the RMC in onboard packet memory. The other pair is used to communicate SMT frames with adapter's firmware. Any SMT frame received from the RMC via the Rx queue must be queued back by the driver to the SMT Rx queue for the firmware to process. Similarly the firmware uses the SMT Tx queue to supply the driver with SMT frames that must be queued back to the Tx queue for the RMC to send to the ring. This solution was chosen because the designers ran out of PCB space and could not squeeze in more logic onto the board that would be required to handle this SMT frame traffic without the need to involve the driver, as with the later DEFTA/DEFEA/DEFPA adapters. Finally the driver does some Frame Control byte decoding, so to avoid magic numbers some macros are added to <linux/if_fddi.h>. Signed-off-by: Maciej W.

2018-10-12net/ipv6: Add knob to skip DELROUTE message on device downDavid Ahern1-0/+8
Another difference between IPv4 and IPv6 is the generation of RTM_DELROUTE notifications when a device is taken down (admin down) or deleted. IPv4 does not generate a message for routes evicted by the down or delete; IPv6 does. A NOS at scale really needs to avoid these messages and have IPv4 and IPv6 behave similarly, relying on userspace to handle link notifications and evict the routes. At this point existing user behavior needs to be preserved. Since notifications are a global action (not per app) the only way to preserve existing behavior and allow the messages to be skipped is to add a new sysctl (net/ipv6/route/skip_notify_on_dev_down) which can be set to disable the notificatioons. IPv6 route code already supports the option to skip the message (it is used for multipath routes for example). Besides the new sysctl we need to pass the skip_notify setting through the generic fib6_clean and fib6_walk functions to fib6_clean_node and to set skip_notify on calls to __ip_del_rt for the addrconf_ifdown path.

Alexei Starovoitov says: ==================== pull-request: bpf-next 2018-10-08 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) sk_lookup_[tcp|udp] and sk_release helpers from Joe Stringer which allow BPF programs to perform lookups for sockets in a network namespace. This would allow programs to determine early on in processing whether the stack is expecting to receive the packet, and perform some action (eg drop, forward somewhere) based on this information. 2) per-cpu cgroup local storage from Roman Gushchin. Per-cpu cgroup local storage is very similar to simple cgroup storage except all the data is per-cpu. The main goal of per-cpu variant is to implement super fast counters (e.g. packet counters), which don't require neither lookups, neither atomic operations in a fast path. The example of these hybrid counters is in selftests/bpf/netcnt_prog.c 3) allow HW offload of programs with BPF-to-BPF function calls from Quentin Monnet 4) support more than 64-byte key/value in HW offloaded BPF maps from Jakub Kicinski 5) rename of libbpf interfaces from Andrey Ignatov. libbpf is maturing as a library and should follow good practices in library design and implementation to play well with other libraries. This patch set brings consistent naming convention to global symbols. 6) relicense libbpf as LGPL-2.1 OR BSD-2-Clause from Alexei Starovoitov to let Apache2 projects use libbpf 7) various AF_XDP fixes from Björn and Magnus ==================== Signed-off-by: David S.

2018-10-04rxrpc: Allow the reply time to be obtained on a client callDavid Howells1-0/+14
Allow the epoch value to be queried on a server connection. This is in the rxrpc header of every packet for use in routing and is derived from the client's state. It's also not supposed to change unless the client gets restarted. AFS can make use of this information to deduce whether a fileserver has been restarted because the fileserver makes client calls to the filesystem driver's cache manager to send notifications (ie. callback breaks) about conflicting changes from other clients. These convey the fileserver's own epoch value back to the filesystem. Signed-off-by: David Howells <dhowells@redhat.com>

Rename the Intel Ethernet Adaptive Virtual Function driver (i40evf) to a new name (iavf) that is more consistent with the ongoing maintenance of the driver as the universal VF driver for multiple product lines. This first patch fixes up the directory names and the .ko name, intentionally ignoring the function names inside the driver for now. Basically this is the simplest patch that gets the rename done and will be followed by other patches that rename the internal functions. This patch also addresses a couple of string/name issues and updates the Copyright year. Also, made sure to add a MODULE_ALIAS to the old name.

2018-09-10Drop all 00-INDEX files from Documentation/Henrik Austad1-234/+0
This is a respin with a wider audience (all that get_maintainer returned) and I know this spams a *lot* of people. Not sure what would be the correct way, so my apologies for ruining your inbox. The 00-INDEX files are supposed to give a summary of all files present in a directory, but these files are horribly out of date and their usefulness is brought into question. Often a simple "ls" would reveal the same information as the filenames are generally quite descriptive as a short introduction to what the file covers (it should not surprise anyone what Documentation/sched/sched-design-CFS.txt covers) A few years back it was mentioned that these files were no longer really needed, and they have since then grown further out of date, so perhaps it is time to just throw them out. A short status yields the following _outdated_ 00-INDEX files, first counter is files listed in 00-INDEX but missing in the directory, last is files present but not listed in 00-INDEX. List of outdated 00-INDEX: Documentation: (4/10) Documentation/sysctl: (0/1) Documentation/timers: (1/0) Documentation/blockdev: (3/1) Documentation/w1/slaves: (0/1) Documentation/locking: (0/1) Documentation/devicetree: (0/5) Documentation/power: (1/1) Documentation/powerpc: (0/5) Documentation/arm: (1/0) Documentation/x86: (0/9) Documentation/x86/x86_64: (1/1) Documentation/scsi: (4/4) Documentation/filesystems: (2/9) Documentation/filesystems/nfs: (0/2) Documentation/cgroup-v1: (0/2) Documentation/kbuild: (0/4) Documentation/spi: (1/0) Documentation/virtual/kvm: (1/0) Documentation/scheduler: (0/2) Documentation/fb: (0/1) Documentation/block: (0/1) Documentation/networking: (6/37) Documentation/vm: (1/3) Then there are 364 subdirectories in Documentation/ with several files that are missing 00-INDEX alltogether (and another 120 with a single file and no 00-INDEX). I don't really have an opinion to whether or not we /should/ have 00-INDEX, but the above 00-INDEX should either be removed or be kept up to date. If we should keep the files, I can try to keep them updated, but I rather not if we just want to delete them anyway. As a starting point, remove all index-files and references to 00-INDEX and see where the discussion is going. Signed-off-by: Henrik Austad <henrik@austad.us> Acked-by: "Paul E.

2018-08-29xfrm: allow driver to quietly refuse offloadShannon Nelson1-0/+4
If the "offload" attribute is used to create an IPsec SA and the .xdo_dev_state_add() fails, the SA creation fails. However, if the "offload" attribute is used on a device that doesn't offer it, the attribute is quietly ignored and the SA is created without an offload. Along the same line of that second case, it would be good to have a way for the device to refuse to offload an SA without failing the whole SA creation. This patch adds that feature by allowing the driver to return -EOPNOTSUPP as a signal that the SA may be fine, it just can't be offloaded. This allows the user a little more flexibility in requesting offloads and not needing to know every detail at all times about each specific NIC when trying to create SAs.

2018-08-16Documentation: networking: ti-cpsw: correct cbs parameters for Eth1 100MbIvan Khoronzhuk1-5/+6
If set cbs parameters calculated for 1000Mb, but use on 100Mb port w/o h/w offload (for cpsw offload it doesn't matter), it works incorrectly. According to the example and testing board, second port is 100Mb interface. Correct them on recalculated for 100Mb interface. It allows to use the same command for CBS software implementation for board in example. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.

Recently, transparent proxy support has been added to nf_tables so that this document should be updated with the new information. - Nft commands are added as alternatives to iptables ones. - The link for a patched iptables is removed as it is already part of the mainline iptables implementation (and the link is dead). - tcprdr is added as an example implementation of a transparent proxy Cc: "David S.

2018-08-13ipv6: Add icmp_echo_ignore_all support for ICMPv6Virgile Jarry1-0/+5
Preventing the kernel from responding to ICMP Echo Requests messages can be useful in several ways. The sysctl parameter 'icmp_echo_ignore_all' can be used to prevent the kernel from responding to IPv4 ICMP echo requests. For IPv6 pings, such a sysctl kernel parameter did not exist. Add the ability to prevent the kernel from responding to IPv6 ICMP echo requests through the use of the following sysctl parameter : /proc/sys/net/ipv6/icmp/echo_ignore_all. Update the documentation to reflect this change. Signed-off-by: Virgile Jarry <virgile@acceis.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-08-01net: ipv4: Control SKB reprioritization after forwardingPetr Machata1-0/+9
After IPv4 packets are forwarded, the priority of the corresponding SKB is updated according to the TOS field of IPv4 header. This overrides any prioritization done earlier by e.g. an skbedit action or ingress-qos-map defined at a vlan device. Such overriding may not always be desirable. Even if the packet ends up being routed, which implies this is an L3 network node, an administrator may wish to preserve whatever prioritization was done earlier on in the pipeline. Therefore introduce a sysctl that controls this behavior. Keep the default value at 1 to maintain backward-compatible behavior.

The UCAN driver supports the microcontroller-based USB/CAN adapters from Theobroma Systems. There are two form-factors that run essentially the same firmware: * Seal: standalone USB stick ( https://www.theobroma-systems.com/seal ) * Mule: integrated on the PCB of various System-on-Modules from Theobroma Systems like the A31-µQ7 and the RK3399-Q7 ( https://www.theobroma-systems.com/rk3399-q7 ) The USB wire protocol has been designed to be as generic and hardware-indendent as possible in the hope of being useful for implementation on other microcontrollers.
