| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, cfg80211 rejects capability updates for existing entries and as a result it's impossible to update entries that were added unassociated, but that is necessary to go through the full station states from userspace, adding a station before authentication etc. Fix this by allowing updates to capabilities for stations that the driver (or mac80211) assigned unassociated state. Drivers setting the full station state support flag must use the new station type for proper operation.

| * mac80211: allow writing TX PN in debugfsJohannes Berg2015-09-291-2/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For certain tests, for example replay detection, it can be useful to be able to influence/set the PN used in outgoing packets. Make it possible to change the TX PN in debugfs. For now, this doesn't support TKIP since I haven't needed it, but there's no reason it couldn't be added if necessary. Note that this must be used very carefully: it could, for example, be used to make "valid replays" where the PN reuse happens on a different TID. This couldn't be done by an attacker since the TID is protected as part of the AAD. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case of "any" wowlan trigger, there is no reason to tear down aggregations, as we want the device to continue working normally. Similarly, there's no reason to tear down aggregations on resume, as they should have been torn down on suspend if needed. However, since the reconfiguration flow is shared with HW restart, tear down aggregations on reconfiguration when we are not resuming. To keep things working after non-wowlan suspend, keep clearing the WLAN_STA_BLOCK_BA flag.

| * mac80211: Copy tx'ed beacons to monitor modeHelmut Schaa2015-09-292-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging wireless powersave issues on the AP side it's quite helpful to see our own beacons that are transmitted by the hardware/driver. However, this is not that easy since beacons don't pass through the regular TX queues. Preferably drivers would call ieee80211_tx_status also for tx'ed beacons but that's not always possible. Hence, just send a copy of each beacon generated by ieee80211_beacon_get_tim to monitor devices when they are getting fetched by the driver. Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by drivers to indicate that they report TX status for beacons.

| * nl80211: put current TX power in interface infoRafał Miłecki2015-09-221-0/+10

Right now the only way to access it is to call some wext ioctl. Let's put TX power in interface info reply (callback is wdev specific) just like we do with current channel. To be consistent (e.g. NL80211_CMD_SET_WIPHY) let's use mBm as na unit. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | It doesn't seem problematic to change the weight for the average beacon signal from 3 to 4, so use DECLARE_EWMA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The direct probe step before authentication was done mostly for two reasons: 1) the BSS data could be stale 2) the beacon might not have included all IEs The concern (1) doesn't really seem to be relevant any more as we time out BSS information after about 30 seconds, and in fact the original patch only did the direct probe if the data was older than the BSS timeout to begin with. This condition got (likely inadvertedly) removed later though. Analysing this in more detail shows that since we mostly use data from the association response, the only real reason for needing the probe response was that the code validates the WMM parameters, and those are optional in beacons. As the previous patches removed that behaviour, we can now remove the direct probe step entirely. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * mac80211: process skb_queue while scanning in HWAndrei Otcheretianski2015-09-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Queued frames aren't processed during scan, which results in an inability to complete the BA session establishment until the scan ends. Since we can't tx frames until the BA agreement setup is complete, it might result in a very large latency during scan. Fix this by allowing to process queued skbs while scanning in HW. This should be ok since the devices which support hw scan should be able to handle tx/rx while scanning. During SW scan, mac80211 drops any txed frames besides probes and NDPs, so it is still needed to delay processing of the queued frames till the SW scan is done.

* | net: Refactor path selection in __ip_route_output_key_hashDavid Ahern2015-10-072-15/+22
| | | | | | | | | | | | | | | | | | | | | | VRF device needs the same path selection following lookup to set source address. Rather than duplicating code, move existing code into a function that is exported to modules. Code move only; no functional change.

* | net: Fix vti use case with oif in dst lookups for IPv6David Ahern2015-10-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | It occurred to me yesterday that 741a11d9e4103 ("net: ipv6: Add RT6_LOOKUP_F_IFACE flag if oif is set") means that xfrm6_dst_lookup needs the FLOWI_FLAG_SKIP_NH_OIF flag set. This latest commit causes the oif to be considered in lookups which is known to break vti. This explains why 58189ca7b274 did not the IPv6 change at the time it was submitted.
