* usbnet: Set link down initially for drivers that update link stateBen Hutchings2009-11-10
| | | | | | | | | | | Some usbnet drivers update link state while others do not due to hardware limitations. Add a flag to distinguish those that do, and set the link down initially for their devices.

| * mac80211: async station powersave handlingJohannes Berg2009-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices require that all frames to a station are flushed when that station goes into powersave mode before being able to send frames to that station again when it wakes up or polls -- all in order to avoid reordering and too many or too few frames being sent to the station when it polls. Normally, this is the case unless the station goes to sleep and wakes up very quickly again. But in that case, frames for it may be pending on the hardware queues, and thus races could happen in the case of multiple hardware queues used for QoS/WMM. Normally this isn't a problem, but with the iwlwifi mechanism we need to make sure the race doesn't happen. This makes mac80211 able to cope with the race with driver help by a new WLAN_STA_PS_DRIVER per-station flag that can be controlled by the driver and tells mac80211 whether it can transmit frames or not. This flag must be set according to very specific rules outlined in the documentation for the function that controls it. When we buffer new frames for the station, we normally set the TIM bit right away, but while the driver has blocked transmission to that sta we need to avoid that as well since we cannot respond to the station if it wakes up due to the TIM bit. Once the driver unblocks, we can set the TIM bit. Similarly, when the station just wakes up, we need to wait until all other frames are flushed before we can transmit frames to that station, so the same applies here, we need to wait for the driver to give the OK.

| * mac80211: make ieee80211_find_sta per virtual interfaceJohannes Berg2009-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we have a TODO item to make all station management dependent on virtual interfaces, I figured I'd start with pushing such a change to drivers before more drivers start using the ieee80211_find_sta() API with a hw pointer and cause us grief later on. For now continue exporting the old API in form of ieee80211_find_sta_by_hw(), but discourage its use strongly. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| * mac80211: deprecate qual valueJohannes Berg2009-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This value is unused by mac80211, because it was only be used by wireless extensions, and turned out to not be useful there because the quality value needs to be comparable between scan results and the current value which is impossible when the qual value is calculated taking into account noise, for example. Since it is unused anyway, this patch deprecates it in the hope that drivers will remove their sometimes quite expensive calculations of the value. I'm open to actual uses of the value, but the best way of using it seems to be what the Intel drivers do which should probably be generalised if we have noise values from the hardware.

| * mac80211: remove RX_FLAG_RADIOTAPJohannes Berg2009-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While there may be a case for a driver adding its own bits of radiotap information, none currently does. Also, drivers would have to copy the code to generate the radiotap bits that now mac80211 generates. If some driver in the future needs to add some driver-specific information I'd expect that to be in a radiotap vendor namespace and we can add a different way of passing such data up and having mac80211 include it. Additionally, rename IEEE80211_CONF_RADIOTAP to IEEE80211_CONF_MONITOR since it's still used by b43(legacy) to obtain per-frame timestamps. The purpose of this patch is to simplify the RX code in mac80211 to make it easier to add paged skb support. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

Quite obviously, that is completely useless. Instead of trying to do that, use unaligned accesses to generate the radiotap header. To properly do that, we also need to mark struct ieee80211_radiotap_header packed, but that is fine since it's already packed (and it should be marked packed anyway since its a wire format).

* | xfrm: SAD entries do not expire correctly after suspend-resumeYury Polyanskiy2009-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following bug in the current implementation of net/xfrm: SAD entries timeouts do not count the time spent by the machine in the suspended state. This leads to the connectivity problems because after resuming local machine thinks that the SAD entry is still valid, while it has already been expired on the remote server. The cause of this is very simple: the timeouts in the net/xfrm are bound to the old mod_timer() timers. This patch reassigns them to the CLOCK_REALTIME hrtimer. I have been using this version of the patch for a few months on my machines without any problems. Also run a few stress tests w/o any issues. This version of the patch uses tasklet_hrtimer by Peter Zijlstra (commit 9ba5f0). This patch is against 2.6.31.4. Please CC me.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no good reason to not support userspace specifying the network namespace during device creation, and it makes it easier to create a network device and pass it to a child network namespace with a well known name. We have to be careful to ensure that the target network namespace for the new device exists through the life of the call. To keep that logic clear I have factored out the network namespace grabbing logic into rtnl_link_get_net. In addtion we need to continue to pass the source network namespace to the rtnl_link_ops.newlink method so that we can find the base device source network namespace. Signed-off-by: Eric W.

However, all this was pretty dirty and not clear, with many open spots where race conditions were present. This commit cleans up the situation by: - documenting the usage of both bits - setting them only in specific, well controlled places (i2400m_dev_start, i2400m_dev_stop) - ensuring the i2400m workqueue can't get in the middle of the setting by flushing it when i2400m->ready is set to zero. This allows the report hook not having to check again for the bit to be set [rx.c:i2400m_report_hook_work()]. - using i2400m->updown to determine if the device is up and running instead of the wimax state in i2400m_dev_reset_handle(). - not loosing missed messages sent by the hardware before i2400m->ready is set. In rx.c, whatever the device sends can be sent to user space over the message pipes as soon as the wimax device is registered, so don't wait for i2400m->ready to be set.

Then the device does a final ack by sending an ACK barker. The first time this happens, we don't know ahead of time with barker the device is going to send, as different device models and SKUs will send different barker depending on the EEPROM programming. If the device has sent the barker before the driver has been able to read it, the driver looses, as it doesn't know which barker it has to echo/ack back. With older devices, we tried a couple of combinations and that always worked; but now, with adding support for more, in which we have an unlimited number of new barkers, that is not an option. So we rework said case so that when the device gets stuck, we just cycle through all the known types until one forces the device to send an ack. Otherwise, the driver gives up and aborts.

| * | | wimax/i2400m: decide properly if using signed vs non-signed firmware loadingInaky Perez-Gonzalez2009-10-19

Signed images have signature data included that must match that of a certificate stored in the device. Currently the code is making the decission on what type of firmware load (signed vs non-signed) is going to be loaded based on a hardcoded decission in __i2400m_ack_verify(), based on the barker the device sent upon boot. This is not flexible enough as future hardware will emit more barkers; thus the bit has to be set in a place where there is better knowledge of what is going on. This will be done in follow-up commits -- however this patch paves the way for it. So the querying of the mode is packed into i2400m_boot_is_signed(); the main changes are just using i2400m_boot_is_signed() to determine the method to follow and setting i2400m->sboot in i2400m_is_boot_barker(). The modifications in i2400m_dnload_init() and i2400m_dnload_finalize() are just reorganizing the order of the if blocks and thus look larger than they really are.

The "cause" of the problem was a fix of unacknowledged data detection with NAT (commit a3a9f79e361e864f0e9d75ebe2a0cb43d17c4272). However, actually, that fix uncovered a long standing bug in TCP conntrack: when NAT was enabled, we simply updated the max of the right edge of the segments we have seen (td_end), by the offset NAT produced with changing IP/port in the data. However, we did not update the other parameter (td_maxend) which is affected by the NAT offset. Thus that could drift away from the correct value and thus resulted breaking active FTP. The patch below fixes the issue by *not* updating the conntrack parameters from NAT, but instead taking into account the NAT offsets in conntrack in a consistent way. (Updating from NAT would be more harder and expensive because it'd need to re-calculate parameters we already calculated in conntrack.)

* | | | | net: pass kern to net_proto_family create functionEric Paris2009-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The generic __sock_create function has a kern argument which allows the security system to make decisions based on if a socket is being created by the kernel or by userspace. This patch passes that flag to the net_proto_family specific create function, so it can do the same thing.
