2010-04-20x86: correctly wire up the newuname system callChristoph Hellwig
Before commit e28cbf22933d0c0ccaf3c4c27a1a263b41f73859 ("improve sys_newuname() for compat architectures") 64-bit x86 had a private implementation of sys_uname which was just called sys_uname, which other architectures used for the old uname. Due to some merge issues with the uname refactoring patches we ended up calling the old uname version for both the old and new system call slots, which lead to the domainname filed never be set which caused failures with libnss_nis.

2010-04-20mac80211: Fix ieee80211_sta_conn_mon_timer with hw connection monitoringJuuso Oikarinen
When IEEE80211_HW_CONNECTION_MONITOR is configured by the driver, starting of ieee80211_sta_conn_mon_timer should be prevented, as it is then not needed. This is currently partially the case. As it seems, when a probe-response is received from the AP the timer is still restarted, thus restarting the host based connection keep-alive mechanism. These probe-responses happen at least when scanning while associated. Fix this by preventing starting of the ieee80211_sta_conn_mon_timer in the ieee80211_rx_mgmt_probe_resp function.

2010-04-20ath9k: Group Key fix for VAPsDaniel Yingqiang Ma
When I set up multiple VAPs with ath9k, I encountered an issue that the traffic may be lost after a while. The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it.

In case we compute a software skb->rxhash, we can generate a consistent hash : Its value will be the same in both flow directions.

2010-04-19rmap: add exclusively owned pages to the newest anon_vmaRik van Riel
The recent anon_vma fixes cause many anonymous pages to end up in the parent process anon_vma, even when the page is exclusively owned by the current process. Adding exclusively owned anonymous pages to the top anon_vma reduces rmap scanning overhead, especially in workloads with forking servers. This patch adds a parameter to __page_set_anon_rmap that can be used to indicate whether or not the added page is exclusively owned by the current process. Pages added through page_add_new_anon_rmap are exclusively owned by the current process, and can be added to the top anon_vma. Pages added through page_add_anon_rmap can be either shared or exclusively owned, so we do the conservative thing and add it to the oldest anon_vma. A next step would be to add the exclusive parameter to page_add_anon_rmap, to be used from functions where we do know for sure whether a page is exclusively owned.

2010-04-19mac80211: Prevent running sta_cleanup timer unnecessarilyJuuso Oikarinen
The sta_cleanup timer is used to periodically expire buffered frames from the tx buf. The timer is executing periodically, regardless of the need for it. This is wasting resources. Fix this simply by not restarting the sta_cleanup timer if the tx buffer was empty. Restart the timer when there is some more tx-traffic.

2010-04-19mac80211: pass HT changes to driver when off channelReinette Chatre
Since "mac80211: make off-channel work generic" drivers have not been notified of configuration changes after association or authentication. This caused more dependence on current state to ensure driver will be notified when configuration changes occur. One such problem arises if off-channel is in progress when HT information changes. Since HT is only enabled on the "oper_channel" the driver will never be notified of this change. Usually the driver is notified soon after of a BSS information change (BSS_CHANGED_HT) ... but since the driver did not get a notification that this is a HT channel the new BSS information does not make sense. Fix this by also changing the off-channel information when HT is enabled and thus cause driver to be notified correctly. This fixes a problem in 4965 when associated with 5GHz 40MHz channel. Without this patch the system can associate but is unable to transfer any data, not even ping.

2010-04-19rps: shortcut net_rps_action()Eric Dumazet
net_rps_action() is a bit expensive on NR_CPUS=64..4096 kernels, even if RPS is not active. Tom Herbert used two bitmasks to hold information needed to send IPI, but a single LIFO list seems more appropriate. Move all RPS logic into net_rps_action() to cleanup net_rx_action() code (remove two ifdefs) Move rps_remote_softirq_cpus into softnet_data to share its first cache line, filling an existing hole. In a future patch, we could call net_rps_action() from process_backlog() to make sure we send IPI before handling this cpu backlog.
