2011-02-23net: Implement SFEATURES compatibility for not updated driversMichał Mirosław
Use discrete setting ops for not updated drivers. This will not make them conform to full G/SFEATURES semantics, though. Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-02-23net: avoid initial "Features changed" messageMichał Mirosław
Avoid "Features changed" message and ndo_set_features call on device registration caused by automatic enabling of GSO and GRO. Driver should have enabled hardware offloads it set in features, so the ndo_set_features() is not needed at registration time.

2011-02-23Fix "(unregistered net_device): Features changed" messageMichał Mirosław
Fix netdev_update_features() messages on register time by moving the call further in register_netdevice(). When netdev->reg_state != NETREG_REGISTERED, netdev_name() returns "(unregistered netdevice)" even if the dev's name is already filled.

2011-02-23net_sched: SFB flow schedulerEric Dumazet
This is the Stochastic Fair Blue scheduler, based on work from : W. Feng, D. Kandlur, D. Saha, K. Shin. Blue: A New Class of Active Queue Management Algorithms. U. Michigan CSE-TR-387-99, April 1999. http://www.thefengs.com/wuchang/blue/CSE-TR-387-99.pdf This implementation is based on work done by Juliusz Chroboczek General SFB algorithm can be found in figure 14, page 15: B[l][n] : L x N array of bins (L levels, N bins per level) enqueue() Calculate hash function values h{0}, h{1}, .. h{L-1} Update bins at each level for i = 0 to L - 1 if (B[i][h{i}].qlen > bin_size) B[i][h{i}].p_mark += p_increment; else if (B[i][h{i}].qlen == 0) B[i][h{i}].p_mark -= p_decrement; p_min = min(B[0][h{0}].p_mark ... B[L-1][h{L-1}].p_mark); if (p_min == 1.0) ratelimit(); else mark/drop with probabilty p_min; I did the adaptation of Juliusz code to meet current kernel standards, and various changes to address previous comments : http://thread.gmane.org/gmane.linux.network/90225 http://thread.gmane.org/gmane.linux.network/90375 Default flow classifier is the rxhash introduced by RPS in 2.6.35, but we can use an external flow classifier if wanted. tc qdisc add dev $DEV parent 1:11 handle 11: \ est 0.5sec 2sec sfb limit 128 tc filter add dev $DEV protocol ip parent 11: handle 3 \ flow hash keys dst divisor 1024 Notes: 1) SFB default child qdisc is pfifo_fast. It can be changed by another qdisc but a child qdisc MUST not drop a packet previously queued. This is because SFB needs to handle a dequeued packet in order to maintain its virtual queue states. pfifo_head_drop or CHOKe should not be used. 2) ECN is enabled by default, unlike RED/CHOKe/GRED With help from Patrick McHardy & Andi Kleen Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Juliusz Chroboczek <Juliusz.Chroboczek@pps.jussieu.fr> CC: Stephen Hemminger <shemminger@vyatta.com> CC: Patrick McHardy <kaber@trash.net> CC: Andi Kleen <andi@firstfloor.org> CC: John W.

2011-02-23mac80211: rename RX_FLAG_TSFTJohannes Berg

2011-02-23mac80211: Fix a race on enabling power save.Vivek Natarajan
There is a race on sending a data frame before the tx completion of nullfunc frame for enabling power save. As the data quickly follows the nullfunc frame, the AP thinks that the station is out of power save and continues to send the frames. Whereas in the station, the nullfunc ack will be processed after the tx completion of data frame and mac80211 goes to powersave. Thus the power save state mismatch between the station and the AP causes some data loss and some applications fail because of that. This patch fixes this issue.

2011-02-22bridge: Use IPv6 link-local address for multicast listener queriesLinus Lüssing
Currently the bridge multicast snooping feature periodically issues IPv6 general multicast listener queries to sense the absence of a listener. For this, it uses :: as its source address - however RFC 2710 requires: "To be valid, the Query message MUST come from a link-local IPv6 Source Address". Current Linux kernel versions seem to follow this requirement and ignore our bogus MLD queries. With this commit a link local address from the bridge interface is being used to issue the MLD query, resulting in other Linux devices which are multicast listeners in the network to respond with a MLD response (which was not the case before).

2011-02-22bridge: Fix MLD queries' ethernet source addressLinus Lüssing
Map the IPv6 header's destination multicast address to an ethernet source address instead of the MLD queries multicast address. For instance for a general MLD query (multicast address in the MLD query set to ::), this would wrongly be mapped to 33:33:00:00:00:00, although an MLD queries destination MAC should always be 33:33:00:00:00:01 which matches the IPv6 header's multicast destination ff02::1.

2011-02-22bridge: Allow mcast snooping for transient link local addresses tooLinus Lüssing
Currently the multicast bridge snooping support is not active for link local multicast. I assume this has been done to leave important multicast data untouched, like IPv6 Neighborhood Discovery. In larger, bridged, local networks it could however be desirable to optimize for instance local multicast audio/video streaming too. With the transient flag in IPv6 multicast addresses we have an easy way to optimize such multimedia traffic without tempering with the high priority multicast data from well-known addresses. This patch alters the multicast bridge snooping for IPv6, to take effect for transient multicast addresses instead of non-link-local addresses.

2011-02-22bridge: Fix IPv6 multicast snooping by correcting offset in MLDv2 reportLinus Lüssing
We actually want a pointer to the grec_nsrcr and not the following field. Otherwise we can get very high values for *nsrcs as the first two bytes of the IPv6 multicast address are being used instead, leading to a failing pskb_may_pull() which results in MLDv2 reports not being parsed.

2011-02-22bridge: Fix IPv6 multicast snooping by storing correct protocol typeLinus Lüssing
The protocol type for IPv6 entries in the hash table for multicast bridge snooping is falsely set to ETH_P_IP, marking it as an IPv4 address, instead of setting it to ETH_P_IPV6, which results in negative look-ups in the hash table later.

2011-02-22HID: bt hidp: send Output reports using SET_REPORT on the Control channelAntonio Ospite
The current implementation of hidp_output_raw_report() relies only on the Control channel even for Output reports, and the BT HID specification [1] does not mention using the DATA message for Output reports on the Control channel (see section 7.9.1 and also Figure 11: SET_ Flow Chart), so let us just use SET_REPORT. This also fixes sending Output reports to some devices (like Sony Sixaxis) which are not able to handle DATA messages on the Control channel. Ideally hidp_output_raw_report() could be improved to use this scheme: Feature Report -- SET_REPORT on the Control channel Output Report -- DATA on the Interrupt channel for more efficiency, but as said above, right now only the Control channel is used.
