2008-12-25forcedeth: don't poll NV event 36Johannes Berg
Polling doesn't seem to be necessary on my hardware, at least I haven't seen any bad effects testing it a while. Remove the polling so the CPU doesn't have to wake up a hundred times per second.

2008-12-25netlink: fix (theoretical) overrun in message iterationVegard Nossum
See commit 1045b03e07d85f3545118510a587035536030c1c ("netlink: fix overrun in attribute iteration") for a detailed explanation of why this patch is necessary. In short, nlmsg_next() can make "remaining" go negative, and the remaining >= sizeof(...) comparison will promote "remaining" to an unsigned type, which means that the expression will evaluate to true for negative numbers, even though it was not intended. I put "theoretical" in the title because I have no evidence that this can actually happen, but I suspect that a crafted netlink packet can trigger some badness. Note that the last test, which seemingly has the exact same problem (also true for nla_ok()), is perfectly OK, since we already know that remaining is positive.

2008-12-25tcp: Always set urgent pointer if it's beyond snd_nxtHerbert Xu
Our TCP stack does not set the urgent flag if the urgent pointer does not fit in 16 bits, i.e., if it is more than 64K from the sequence number of a packet. This behaviour is different from the BSDs, and clearly contradicts the purpose of urgent mode, which is to send the notification (though not necessarily the associated data) as soon as possible. Our current behaviour may in fact delay the urgent notification indefinitely if the receiver window does not open up. Simply matching BSD however may break legacy applications which incorrectly rely on the out-of-band delivery of urgent data, and conversely the in-band delivery of non-urgent data. Alexey Kuznetsov suggested a safe solution of following BSD only if the urgent pointer itself has not yet been transmitted. This way we guarantee that when the remote end sees the packet with non-urgent data marked as urgent due to wrap-around we would have advanced the urgent pointer beyond, either to the actual urgent data or to an as-yet untransmitted packet. The only potential downside is that applications on the remote end may see multiple SIGURG notifications. However, this would occur anyway with other TCP stacks. More importantly, the outcome of such a duplicate notification is likely to be harmless since the signal itself does not carry any information other than the fact that we're in urgent mode.

2008-12-19mac80211: implement dynamic power saveKalle Valo
This patch implements dynamic power save for mac80211. Basically it means enabling power save mode after an idle period. Implementing it dynamically gives a good compromise of low power consumption and low latency. Some hardware have support for this in firmware, but some require the host to do it. The dynamic power save is implemented by adding an timeout to ieee80211_subif_start_xmit(). The timeout can be enabled from userspace with Wireless Extensions. For example, the command below enables the dynamic power save and sets the time timeout to 500 ms: iwconfig wlan0 power timeout 500m Power save now only works with devices which handle power save in firmware. It's also disabled by default and the heuristics when and how to enable is considered as a policy decision and will be left for the userspace to handle. In case the firmware has support for this, drivers can disable this feature with IEEE80211_HW_NO_STACK_DYNAMIC_PS. Big thanks to Johannes Berg for the help with the design and code.

2008-12-19ath9k: Fixed RX decryption status reportingJouni Malinen
The RX code in ath9k uses sc_keymap to figure out whether a default key was used. However, the default key entries in sc_keymap were always set and as such, frames could have been claimed to be decrypted by hardware when they were not. This can cause problems especially with TKIP since mac80211 is validating the Michael MIC in the frame and this will result in MIC failure and potentially TKIP countermeasures if the frame was not decrypted correctly. Change key cache slot allocation to mark only the keys that really have been used in sc_keymap to avoid the issue. The key cache slot selection routines are now internally avoiding the slots that may be needed for TKIP group keys. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
