The B.A.T.M.A.N. protocol originally only used a single message type (called OGM) to determine the link qualities to the direct neighbors and spreading these link quality information through the whole mesh. This procedure is summarized on the BATMAN concept page and explained in details in the RFC draft published in 2008. This approach was chosen for its simplicity during the protocol design phase and the implementation. However, it also bears some drawbacks: * Wireless interfaces usually come with some packet loss, therefore a higher broadcast rate is desirable to allow a fast reaction on flaky connections. Other interfaces of the same host might be connected to Ethernet LANs / VPNs / etc which rarely exhibit packet loss would benefit from a lower broadcast rate to reduce overhead. * It generally is more desirable to detect local link quality changes at a faster rate than propagating all these changes through the entire mesh (the far end of the mesh does not need to care about local link quality changes that much). Other optimizations strategies, like reducing overhead, might be possible if OGMs weren't used for all tasks in the mesh at the same time. As a result detecting local link qualities shall be handled by an independent message type, ELP, whereas the OGM message type remains responsible for flooding the mesh with these link quality information and determining the overall path transmit qualities.

This allows us to easily add a sysfs parameter for an unsigned int later, which is not for a batman mesh interface (e.g. bat0), but for a common interface instead. It allows reading and writing an atomic_t in hard_iface (instead of bat_priv compared to the mesh variant). Developed by Linus during a 6 months trainee study period in Ascom (Switzerland) AG.

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2016-02-24 This series contains updates to e1000e, igb and igbvf. Raanan provides updates for e1000e, first increases the ULP timer since it now takes longer for the ULP exit to complete on Skylake. Fixes the configuration of the internal hardware PHY clock gating mechanism, which was causing packet loss due to mis configuring. Fixed additional ULP configuration settings which were not being properly cleared after cable connect in V-Pro capable systems. Added support for more i219 devices. Takuma Ueba provides a fix for I210 where IPv6 autoconf test sometimes fails due to DAD NS for link-local is not transmitted. To avoid this issue, we need to wait until 1000BASE-T status register "Remote receiver status OK". Todd provides a patch to override EEPROM WoL settings for specific OEM devices. Then renamed igb defines to be more generic, since the define E1000_MRQC_ENABLE_RSS_4Q enables 4 and 8 queues depending on the part. Roland Hii fixes an issue where only the half cycle time of less than or equal to 70 millisecond uses the I210 clock output function. His patch adds additional conditions when half cycle time is equal to 125 or 250 or 500 millisecond to use the clock output function. Alex Duyck adds support for generic transmit checksums for igb and igbvf. Jon Maxwell fixes an issues where customer applications are registering and un-registering multicast addresses every few seconds which is leading to many "Link is up" messages in the logs as a result of the netif_carrier_off(netdev) in igbvf_msix_other(). So remove the link is up message when registering multicast addresses. Corinna Vinschen provides a fix for when switching off VLAN offloading on i350, the VLAN interface becomes unusable. Stefan Assmann updates the driver to use ndo_stop() instead of dev_close() when running ethtool offline self test. Since dev_close() causes IFF_UP to be cleared which will remove the interfaces routes and some addresses. v2: Dropped patches 6-10 in the original series. Patch 6-7 added support for character device for AVB and based on community feedback, we do not want to do this. Patches 8-10 provided fixes to the problematic code added in patches 6 & 7.

On reviewing the code I realized that GRE and UDP tunnels could cause a kernel panic if we used GSO to segment a large UDP frame that was sent through the tunnel with an outer checksum and hardware offloads were not available. In order to correct this we need to update the feature flags that are passed to the skb_segment function so that in the event of UDP fragmentation being requested for the inner header the segmentation function will correctly generate the checksum for the payload if we cannot segment the outer header.

When selecting an address in context of a VRF, the vrf master should be preferred for address selection. If it isn't, the user has a hard time getting the system to select to their preference - the code will pick the address off the first in-VRF interface it can find, which on a router could well be a non-routable address.

The ipv4 function for selecting source address takes a const argument. Removing the const requires touching a lot of places, so instead l3mdev_master_ifindex_rcu is changed to take a const argument and then do the typecast to non-const as required by netdev_master_upper_dev_get_rcu. This is similar to what l3mdev_fib_table_rcu does. IPv6 for unnumbered interfaces appears to be selecting the addresses properly.

David Decotigny says: ==================== new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API History: v9 - add 'link' in macro, struct and function names - rename ethtool_link_ksettings::parent -> ::base - remove un-needed mlx4 en_dbg_enabled() companion patch - note: bitmap u32[] API patches were merged separately by Kan Liang v8 - bitmap u32 API returns number of bits copied, unit tests updated v7 - module_exit in test_bitmap v6 - fix copy_from_user in user/kernel handshake v5 note: please see v4 bullets for a question regarding bitmap.c - minor fix to make allyesconfig/allmodconfig v4 - removed typedef for link mode bitmaps - moved bitmap<->u32[] conversion routines to bitmap.c . This is the naive implementation. I have an endian-aware version that uses memcpy/memset as much as possible, but I find it harder to follow (see http://paste.ubuntu.com/13863722/). Please let me know if I should use it instead. - fixes suggested by Ben Hutchings v3 - rebased v2 on top of latest net-next, minor checkpatch/printf %*pb updates v2 - keep return 0 in get_settings when successful, instead of propagating positive result from driver's get_settings callback. v1 - original submission The main goal of this series is to support ethtool link mode masks larger than 32 bits. It implements a new ioctl pair (ETHTOOL_GLINKSETTINGS/SLINKSETTINGS), its associated callbacks (get/set_link_ksettings) and a new struct ethtool_link_settings, which should eventually replace legacy ethtool_cmd. Internally, the kernel uses fixed length link mode masks defined at compilation time in ethtool.h (for now: 31 bits), that can be increased by changing __ETHTOOL_LINK_MODE_LAST in ethtool.h (absolute max is 4064 bits, checked at compile time), and the user/kernel interface allows this length to be arbitrary within 1..4064. This should allow some flexibility without using too much heap/stack space, at the cost of a small kernel/user handshake for the user to determine the sizes of those bitmaps. Along the way, I chose to drop in the new structure the 3 ethtool_cmd fields marked "deprecated" (transceiver/maxrxpkt/maxtxpkt). They are still available for old drivers via the (old) ETHTOOL_GSET/SSET API, but are not available to drivers that switch to new API. Of those 3 fields, ethtool_cmd::transceiver seems to be still actively used by several drivers, maybe we should not consider this field deprecated? The 2 other fields are basically not used. This transition requires some care in the way old and new ethtool talk to the kernel. More technical details provided in the description for main patch. In particular details about backward compatibility properties. Some open questions: - the kernel/interface multiplexes the "tell me the bitmap length" handshake and the "give me the settings" inside the new ETHTOOL_GLINKSETTINGS cmd. I was thinking of making this into 2 separate cmds: 1 cmd ETHTOOL_GKERNELPROPERTIES which would be kernel-wide rather than device-specific, would return properties like "length of the link mode bitmaps", and possibly others. And ETHTOOL_GLINKSETTINGS would expect the proper bitmaps - the link mode bitmaps are piggybacked at tail of the new struct ethtool_link_settings. Since its user-visible definition does not assume specific bitmap width, I am using a 0-length array as the publicly visible placeholder. But then, the kernel needs to specialize it (struct ethtool_link_ksettings) to specify its current link mode masks. This means that kernel code is "littered" with "ksettings->base.field" to access "field" inside ethtool_settings: + I could use ethtool_link_settings everywhere (instead of a new ethtool_ksettings) and an container_of accessor (or a plain cast) to retrieve the link mode masks? + or: we could decide to make the link mode masks statically bounded again, ie. make their width public, but larger than current 32, and unchangeable forever. This would make everything straightforward, but we might hit limits later, or have an unneeded memory/stack usage for unused bits. any preference? - I foresee bugs where people use the legacy/deprecated SUPPORTED_x macros instead of the new ETHTOOL_LINK_MODE_x_BIT enums in the new get/set_link_ksettings callbacks. Not sure how to prevent problems with this. The only driver which was converted for now is mlx4. I am not considering fcoe as fully converted, but I updated it a minima to be able to remove __ethtool_get_settings, now known as __ethtool_get_link_ksettings. Tested with legacy and "future" ethtool on 64b x86 kernel and 32+64b ethtool, and on a 32b x86 kernel + 32b ethtool. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch defines a new ETHTOOL_GLINKSETTINGS/SLINKSETTINGS API, handled by the new get_link_ksettings/set_link_ksettings callbacks. This API provides support for most legacy ethtool_cmd fields, adds support for larger link mode masks (up to 4064 bits, variable length), and removes ethtool_cmd deprecated fields (transceiver/maxrxpkt/maxtxpkt). This API is deprecating the legacy ETHTOOL_GSET/SSET API and provides the following backward compatibility properties: - legacy ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks. - legacy ethtool with new get/set_link_ksettings drivers: the new driver callbacks are used, data internally converted to legacy ethtool_cmd. ETHTOOL_GSET will return only the 1st 32b of each link mode mask. ETHTOOL_SSET will fail if user tries to set the ethtool_cmd deprecated fields to non-0 (transceiver/maxrxpkt/maxtxpkt). A kernel warning is logged if driver sets higher bits. - future ethtool with legacy drivers: no change, still using the get_settings/set_settings callbacks, internally converted to new data structure. Deprecated fields (transceiver/maxrxpkt/maxtxpkt) will be ignored and seen as 0 from user space. Note that that "future" ethtool tool will not allow changes to these deprecated fields. - future ethtool with new drivers: direct call to the new callbacks. By "future" ethtool, what is meant is: - query: first try ETHTOOL_GLINKSETTINGS, and revert to ETHTOOL_GSET if fails - set: query first and remember which of ETHTOOL_GLINKSETTINGS or ETHTOOL_GSET was successful + if ETHTOOL_GLINKSETTINGS was successful, then change config with ETHTOOL_SLINKSETTINGS. A failure there is final (do not try ETHTOOL_SSET). + otherwise ETHTOOL_GSET was successful, change config with ETHTOOL_SSET. A failure there is final (do not try ETHTOOL_SLINKSETTINGS). The interaction user/kernel via the new API requires a small ETHTOOL_GLINKSETTINGS handshake first to agree on the length of the link mode bitmaps. If kernel doesn't agree with user, it returns the bitmap length it is expecting from user as a negative length (and cmd field is 0). When kernel and user agree, kernel returns valid info in all fields (ie. link mode length > 0 and cmd is ETHTOOL_GLINKSETTINGS). Data structure crossing user/kernel boundary is 32/64-bit agnostic. Converted internally to a legal kernel bitmap. The internal __ethtool_get_settings kernel helper will gradually be replaced by __ethtool_get_link_ksettings by the time the first "link_settings" drivers start to appear. So this patch doesn't change it, it will be removed before it needs to be changed. Signed-off-by: NDavid Decotigny <decot@googlers.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch add the SO_CNX_ADVICE socket option (setsockopt only). The purpose is to allow an application to give feedback to the kernel about the quality of the network path for a connected socket. The value argument indicates the type of quality report. For this initial patch the only supported advice is a value of 1 which indicates "bad path, please reroute"-- the action taken by the kernel is to call dst_negative_advice which will attempt to choose a different ECMP route, reset the TX hash for flow label and UDP source port in encapsulation, etc. This facility should be useful for connected UDP sockets where only the application can provide any feedback about path quality. It could also be useful for TCP applications that have additional knowledge about the path outside of the normal TCP control loop.

When the TIPC module is unloaded, we have identified a race condition that allows a node reference counter to go to zero and the node instance being freed before the node timer is finished with accessing it. This leads to occasional crashes, especially in multi-namespace environments. The scenario goes as follows: CPU0:(node_stop) CPU1:(node_timeout) // ref == 2 1: if(!mod_timer()) 2: if (del_timer()) 3: tipc_node_put() // ref -> 1 4: tipc_node_put() // ref -> 0 5: kfree_rcu(node); 6: tipc_node_get(node) 7: // BOOM! We now clean up this functionality as follows: 1) We remove the node pointer from the node lookup table before we attempt deactivating the timer. This way, we reduce the risk that tipc_node_find() may obtain a valid pointer to an instance marked for deletion; a harmless but undesirable situation. 2) We use del_timer_sync() instead of del_timer() to safely deactivate the node timer without any risk that it might be reactivated by the timeout handler. There is no risk of deadlock here, since the two functions never touch the same spinlocks. 3: We remove a pointless tipc_node_get() + tipc_node_put() from the timeout handler.
