2012-10-18cfg80211: fix antenna gain handlingFelix Fietkau
No driver initializes chan->max_antenna_gain to something sensible, and the only place where it is being used right now is inside ath9k. This leads to ath9k potentially using less tx power than it can use, which can decrease performance/range in some rare cases. Rather than going through every single driver, this patch initializes chan->orig_mag in wiphy_register(), ignoring whatever value the driver left in there. If a driver for some reason wishes to limit it independent from regulatory rulesets, it can do so internally.

2012-10-17mac80211: connect with HT20 if HT40 is not permittedJohannes Berg
Some changes to fix issues with HT40 APs in Korea and follow-up changes to allow using HT40 even if the local regulatory database disallows it caused issues with iwlwifi (and could cause issues with other devices); iwlwifi firmware would assert if you tried to connect to an AP that has an invalid configuration (e.g. using HT40- on channel 140.) Fix this, while avoiding the "Korean AP" issue by disabling HT40 and advertising HT20 to the AP when connecting.

2012-10-04tipc: prevent dropped connections due to rcvbuf overflowErik Hugne
When large buffers are sent over connected TIPC sockets, it is likely that the sk_backlog will be filled up on the receiver side, but the TIPC flow control mechanism is happily unaware of this since that is based on message count. The sender will receive a TIPC_ERR_OVERLOAD message when this occurs and drop it's side of the connection, leaving it stale on the receiver end. By increasing the sk_rcvbuf to a 'worst case' value, we avoid the overload caused by a full backlog queue and the flow control will work properly. This worst case value is the max TIPC message size times the flow control window, multiplied by two because a sender will transmit up to double the window size before a port is marked congested. We multiply this by 2 to account for the sk_buff and other overheads. Signed-off-by: Erik Hugne <erik.hugne@ericsson.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-10-04sctp: check src addr when processing SACK to update transport stateNicolas Dichtel
Suppose we have an SCTP connection with two paths. After connection is established, path1 is not available, thus this path is marked as inactive. Then traffic goes through path2, but for some reasons packets are delayed (after rto.max). Because packets are delayed, the retransmit mechanism will switch again to path1. At this time, we receive a delayed SACK from path2. When we update the state of the path in sctp_check_transmitted(), we do not take into account the source address of the SACK, hence we update the wrong path.

2012-10-04ipv4: add a fib_type to fib_infoEric Dumazet
commit d2d68ba9fe8 (ipv4: Cache input routes in fib_info nexthops.) introduced a regression for forwarding. This was hard to reproduce but the symptom was that packets were delivered to local host instead of being forwarded. David suggested to add fib_type to fib_info so that we dont inadvertently share same fib_info for different purposes. With help from Julian Anastasov who provided very helpful hints, reproduced here : <quote> Can it be a problem related to fib_info reuse from different routes. For example, when local IP address is created for subnet we have: broadcast 192.168.0.255 dev DEV proto kernel scope link src 192.168.0.1 192.168.0.0/24 dev DEV proto kernel scope link src 192.168.0.1 local 192.168.0.1 dev DEV proto kernel scope host src 192.168.0.1 The "dev DEV proto kernel scope link src 192.168.0.1" is a reused fib_info structure where we put cached routes. The result can be same fib_info for 192.168.0.255 and 192.168.0.0/24. RTN_BROADCAST is cached only for input routes. Incoming broadcast to 192.168.0.255 can be cached and can cause problems for traffic forwarded to 192.168.0.0/24. So, this patch should solve the problem because it separates the broadcast from unicast traffic. And the ip_route_input_slow caching will work for local and broadcast input routes (above routes 1 and 3) just because they differ in scope and use different fib_info. </quote> Many thanks to Chris Clayton for his patience and help.

This patch fixes a bug in the method used for calculating the trigger alignment for SDP0 when enabling a PPS output on the X540. The alignment math wasn't properly taking into account the overflow cyclecounter, and was misaligning the pin triggers so that two X540 devices synced properly had mis-aligned SDP pins. This patch fixes the math to calculate the correct seconds alignment for the PPS signal.

2012-10-02ipv6: don't add link local route when there is no link local addressNicolas Dichtel
When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), a route to fe80::/64 is added in the main table: unreachable fe80::/64 dev lo proto kernel metric 256 error -101 This route does not match any prefix (no fe80:: address on lo). In fact, addrconf_dev_config() will not add link local address because this function filters interfaces by type. If the link local address is added manually, the route to the link local prefix will be automatically added by addrconf_add_linklocal(). Note also, that this route is not deleted when the address is removed. After looking at the code, it seems that addrconf_add_lroute() is redundant with addrconf_add_linklocal(), because this function will add the link local route when the link local address is configured.

2012-10-02workqueue: avoid using deprecated functionsLinus Torvalds
The network merge brought in a few users of functions that got deprecated by the workqueue cleanups: the 'system_nrt_wq' is now the same as the regular system_wq, since all workqueues are now non- reentrant. Similarly, remove one use of flush_work_sync() - the regular flush_work() has become synchronous, and the "_sync()" version is thus deprecated as being superfluous.
