* irda: Fix build failures after IRDA_DEBUG->pr_debugJoe Perches2014-11-126-18/+6

* ip_tunnel: Ops registration for secondary encap (fou, gue)Tom Herbert2014-11-122-25/+138
| | | | | | | | | | | | | | | | Instead of calling fou and gue functions directly from ip_tunnel use ops for these that were previously registered. This patch adds the logic to add and remove encapsulation operations for ip_tunnel, and modified fou (and gue) to register with ip_tunnels. This patch also addresses a circular dependency between ip_tunnel and fou that was causing link errors when CONFIG_NET_IP_TUNNEL=y and CONFIG_NET_FOU=m. References to fou an gue have been removed from ip_tunnel.c Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S.

| | | | | | | | | | | Currently there are only three neigh tables in the whole kernel: arp table, ndisc table and decnet neigh table. What's more, we don't support registering multiple tables per family. Therefore we can just make these tables statically built-in. Cc: David S.

* net: Convert LIMIT_NETDEBUG to net_dbg_ratelimitedJoe Perches2014-11-1120-102/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the more common dynamic_debug capable net_dbg_ratelimited and remove the LIMIT_NETDEBUG macro. All messages are still ratelimited. Some KERN_<LEVEL> uses are changed to KERN_DEBUG. This may have some negative impact on messages that were emitted at KERN_INFO that are not not enabled at all unless DEBUG is defined or dynamic_debug is enabled. Even so, these messages are now _not_ emitted by default. This also eliminates the use of the net_msg_warn sysctl "/proc/sys/net/core/warnings". For backward compatibility, the sysctl is not removed, but it has no function. The extern declaration of net_msg_warn is removed from sock.h and made static in net/core/sysctl_net_core.c Miscellanea: o Update the sysctl documentation o Remove the embedded uses of pr_fmt o Coalesce format fragments o Realign arguments Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OVS need to flow key for flow lookup in recic action. OVS does key extract in recic action. Most of cases we could use OVS_CB packet key directly and can avoid packet flow key extract. SET action we can update flow-key along with packet to keep it consistent. But there are some action like MPLS pop which forces OVS to do flow-extract. In such cases we can mark flow key as invalid so that subsequent recirc action can do full flow extract.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OVS vswitch has extended IPFIX exporter to export tunnel headers to improve network visibility. To export this information userspace needs to know egress tunnel for given packet. By extending packet attributes datapath can export egress tunnel info for given packet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alternative to RPS/RFS is to use hardware support for multiple queues. Then split a set of million of sockets into worker threads, each one using epoll() to manage events on its own socket pool. Ideally, we want one thread per RX/TX queue/cpu, but we have no way to know after accept() or connect() on which queue/cpu a socket is managed. We normally use one cpu per RX queue (IRQ smp_affinity being properly set), so remembering on socket structure which cpu delivered last packet is enough to solve the problem. After accept(), connect(), or even file descriptor passing around processes, applications can use : int cpu; socklen_t len = sizeof(cpu); getsockopt(fd, SOL_SOCKET, SO_INCOMING_CPU, &cpu, &len); And use this information to put the socket into the right silo for optimal performance, as all networking stack should run on the appropriate cpu, without need to send IPI (RPS/RFS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sk_mark_napi_id() is used to record for a flow napi id of incoming packets for busypoll sake. We should do this only on established flows, not on listeners. This was 'working' by virtue of the socket cloning, but doing this on SYN packets in unecessary cache line dirtying. Even if we move sk_napi_id in the same cache line than sk_lock, we are working to make SYN processing lockless, so it is desirable to set sk_napi_id only for established flows.

The vast majority of patches are for ieee802154 from Alexander Aring with various fixes and cleanups. There are also several LE/SMP fixes as well as improved support for handling LE devices that have lost their pairing information (the patches from Alfonso). Jukka provides a couple of stability fixes for 6lowpan and Szymon conformance fixes for RFCOMM. For the HCI drivers we have one new USB ID for an Acer controller as well as a reset handling fix for H5." For the Atheros bits, Kalle says: "Major changes are: o ethtool support (Ben) o print dev string prefix with debug hex buffers dump (Michal) o debugfs file to read calibration data from the firmware verification purposes (me) o fix fw_stats debugfs file, now results are more reliable (Michal) o firmware crash counters via debugfs (Ben&me) o various tracing points to debug firmware (Rajkumar) o make it possible to provide firmware calibration data via a file (me) And we have quite a lot of smaller fixes and clean up." For the iwlwifi bits, Emmanuel says: "The big new thing here is netdetect which allows the firmware to wake up the platform when a specific network is detected. Along with that I have fixes for d3 operation. The usual amount of rate scaling stuff - we now support STBC. The other commit that stands out is Johannes's work on devcoredump. He basically starts to use the standard infrastructure he built." Along with that are the usual sort of updates and such for ath9k, brcmfmac, wil6210, and a handful of other bits here and there...

To fix this, treat the RIC element specially, and stop after it only when we find something that doesn't actually belong to it. This assumes userspace is actually correctly building it, directly after the fast BSS transition IE and before all the others like extended capabilities. This leaves as a potential problem the case where userspace is building the following IEs: [RDE] [vendor resource description] [vendor non-resource IE] In this case, we'd erroneously consider all three IEs to be part of the RIC data together, and not split them between the two vendor IEs. Unfortunately, it isn't easily possible to distinguish vendor IEs, so this isn't easy to fix. Luckily, this case is rare as normally wpa_supplicant will include an extended capabilities IE in the IEs, and that certainly will break the two vendor IEs apart correctly.

When communicating in OCB mode a mandatory wildcard BSSID (48 '1' bits) is used. The EDCA parameters handling function was changed to support 802.11p specific values. The insertion of a newly discovered STAs is done in the similar way as in the IBSS mode -- through the deferred insertion. The OCB mode uses a periodic 'housekeeping task' for expiration of disconnected STAs (in the similar manner as in the MESH mode). New Kconfig option for verbose OCB debugging outputs is added.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During reconfig the station list is traversed in order and station are added back to the driver. Make sure the stations are added to the driver in the same order they were added to mac80211. This has a real side effect - some drivers (iwlwifi) require TDLS stations to be added only after the AP station for the same network.

| | * | mac80211: minstrel_ht: use group flags instead of index to display ratesKarl Beldan2014-10-231-12/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When displaying a rate through debugfs minstrel_ht guesses its flags comparing group indexes. Since 3ec373c421b6 ("mac80211: minstrel_ht: include type (cck/ht) in rates flag"), the rate flags of interest are present in the mcs_group-s, so use it. While improving the code, this also fixes a smatch false positive "error: testing array offset 'i' after use" in minstrel_ht_stats_dump. This warning only triggers after 9208247d74bc ("mac80211: minstrel_ht: add basic support for VHT rates <= 3SS@80MHz") with CONFIG_MAC80211_RC_MINSTREL_VHT unset because then MINSTREL_VHT_GROUP_0 is above MINSTREL_GROUPS_NB and smatch only barks when the "testing array offset" seems to prevent possible out of bonds accesses (which does not happen here since i < ARRAY_SIZE(mi->groups)).

| | * | mac80211: add WMM admission control supportJohannes Berg2014-10-227-22/+270

The low level driver needs to report the media time used by each transmitted packet in ieee80211_tx_status. Based on that information, mac80211 will modify the QoS parameters of the admission controlled Access Category when the limit is reached. Once the original QoS parameters can be restored, mac80211 will do so. One issue with this approach is that management frames will also erroneously be downgraded, but the upside is that the implementation is simple. In the future, it can be extended to driver- or device-based implementations that are better.

This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases. Note: this change isn't needed in 3.18 as there's no driver there yet that supports the functionality at all. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Otherwise MCS_GROUP_RATES is 10, and a module parameter *vht_only* (default 'true'), restricts the rates selection to VHT when VHT is supported.
