Since mac80211_hwsim supports multiple virtual interfaces, we need to iterate through all active interfaces when figuring out whether there is a match during TX Ack status checking. This fixes TX status reporting for cases where secondary interfaces are used. Signed-off-by:

When hw rate control is used, these parameters have no meaning because the hardware cannot get at them right now, so disallow setting them. Also clean up the function a bit. Signed-off-by:

mesh_autostart_enabled was nowhere set. Rumor is that this is used in the OLPC tree, but they never did submit their code upstream. After removing this code, it turned out that the sync_channel stuff is now also unused, so get rid of that as well. Signed-off-by:

Both variables contained the same information (no mesh, old mesh, new mesh). So we can get rid of one variable. Also move the mesh-version test from cmd.c into mesh.c. Signed-off-by:

Clean out some cruft that could use an already existing sta_info struct -- that case cannot happen. Also, there's a bug there -- if allocation/insertion fails then it is possible that we are left in a lingering state where mac80211 waits for the AP, cfg80211 waits for mac80211, but the AP has already replied. Since there's no way to indicate an internal error, pretend there was a timeout, i.e. that the AP never responded. Signed-off-by:

Before commit ca9034592823e8179511e48a78731f95bfdd766c Author: Holger Schurig <hs4233@mail.mn-solutions.de> Date: Tue Oct 13 13:45:28 2009 +0200 cfg80211: remove warning in deauth case we assumed that drivers never give us spurious deauth frames because they filter them out based on the auth state they keep track of. This turned out to be racy, because userspace might deauth while the AP is also sending a deauth frame, so the warning was removed. However, in that case we should not tell userspace about the AP's frame if it requested deauth "first", where "first" means it came to cfg80211 first. Signed-off-by: -

In some situations it is required that a system be configured with no support for 40 MHz channels in the 2.4 GHz band. Rather than imposing any such restrictions on everybody, allow configuration a system like that with a module parameter. It is writable at runtime but only takes effect at the time of the next association. Signed-off-by:

Not that we actually ever aggregate anything, but it could potentially be useful anyhow to simulate aggregation sessions. Signed-off-by:

Enable spatial multiplexing in mac80211 by telling the driver what to do and, where necessary, sending action frames to the AP to update the requested SMPS mode. Also includes a trivial implementation for hwsim that just logs the requested mode. For now, the userspace interface is in debugfs only, and let you toggle the requested mode at any time.

When the device receives an A-MSDU frame (indicated by flag IWM_RX_TICKET_AMSDU_MSK), use ieee80211_amsdu_to_8023s to convert it to a list of 802.3 frames and handled them to upper layer. Cc: Johannes Berg <johannes@sipsolutions.net> Acked-by:

Move the A-MSDU handling code from mac80211 to cfg80211 so that more drivers can use it. The new created function ieee80211_amsdu_to_8023s converts an A-MSDU frame to a list of 802.3 frames. Cc: Johannes Berg <johannes@sipsolutions.net> Signed-off-by:

The mac80211 tkip code won't call update_tkip_key, if rx packets are received without KEY_FLAG_UPLOADED_TO_HARDWARE. This can happen on first packet because the hardware key stuff is called asynchronously with todo workqueue. This patch workaround that by tracking if we sent the key to the driver. Signed-off-by:

Ensure that frames without payload are properly trimmed in rt2x00queue_insert_l2pad. This should fix the bug reported by Benoit Papillault in: http://marc.info/?l=linux-wireless&m=125974773006734&w=2Signed-off-by:

According to Ralink source code, the RX frame format is RXINFO + RXWI + 802.11 frame + RXD, including various padding. Before this patch, we were using RXD + RXWI + 802.11 frame, so RXD was not correct. Doing this, we fix the L2PAD bit which is now correctly set on received frames. Signed-off-by:

RX aggregation is a way to receive multiple 802.11 frames in one RX buffer. However, we don't know yet how to handle this case in rt2800usb_fill_rxdone and this has probably no impact on RX performance as well, so we disable it Signed-off-by:

Simplify the rt2x00queue_insert_l2pad function by handling the alignment operations one by one. Do not special case special circumstances. Basically first perform header alignment, and then perform payload alignment (if any payload does exist). This results in a properly aligned skb. The end result is better readable code, with better results, as now L2 padding is inserted only when a payload is actually present in the frame. Signed-off-by:
-
Gertjan van Wingerde authored
With the improved L2 padding code, this flag is no longer necessary, as the rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is applied. For received frames the RX descriptor flag is still being checked. Signed-off-by:

Gertjan van Wingerde authored
Fix a couple of more bugs in the L2 padding code: 1. Compute the amount of L2 padding correctly (in 3 places). 2. Trim the skb correctly when the L2 padding has been applied. Also introduce a central macro the compute the L2 padding size. Signed-off-by:
-
Alban Browaeys authored
Otherwise we end up truncating the skb before removing the l2pad thus we might have the truncated part become garbage while getting it back in remove_l2pad. For the same issue: remove the skb_trim from the rt2800 fill_rxdone (it is done after l2pad removal in rt2x00lib_rxdone). Signed-off-by:

Do not need to log error when fail the sensitivity command, driver will send sensitivity write command to uCode after each sensitivity calibration if station is associated with AP. It is a normal case when user unload the module or shutdown the system while still associated with the AP, since uCode already on the way down, it will not reply the sensitivity write request; report error in this case will give misleading information, remove the error checking here to provide a clean shutdown if no other error detected.

This feature enables the on-screen uCode event log dump. The original method will append the event log to syslog; with this capability, we also enable the user to write script to capture the events which provide additional flexibility to help uCode debugging Method 1) change to debugfs directory (sys/kernel/debug/phyX/iwlagn/data) 2) #cat log_event Signed-off-by:

In order to help uCode debugging, adding the capability to provide continuous uCode event logging function. uCode events is located in round-robin event queue and filled by uCode, by enable continuous event logging, driver check the write pointer and log the newly added events in iwl_bg_ucode_trace() timer function. There is still possibility of missing events if event queue being wrapped before next event dump; but with this capability, we can have much better understanding of the uCode behavior during runtime; it can help to debug the uCode related issues. Methods to enable/disable the continuous event log: step 1: enable ucode trace timer "echo 1 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" step 2: start ftrace sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d step 3: stop ftrace sudo ./trace-cmd report trace.dat step 4: disable ucode trace timer "echo 0 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" use "ucode_tracing" debugfs file to display number of event queue wrapped when driver attempt the continuous event logging. If event queue being wrapped more than once when driver has opportunity to log the event; it indicated there are events missing in the event log trace. This continuous event log function only available for 4965 and newer NICs. Signed-off-by: -

This patch provides infrastructure for machine translation of the regulatory rules database used by CRDA into a C data structure. It includes code for searching that database as an alternative to dynamic regulatory rules updates via CRDA. Most people should use CRDA instead of this infrastructure, but it provides a better alternative than the WIRELESS_OLD_REGULATORY infrastructure (which can now be removed). Signed-off-by: -

The payload alignment warning enabled by MAC80211_DEBUG_PACKET_ALIGNMENT is difficult. To fix it, a firmware change is needed but in most cases that's very difficult. So the benefit from the warning is low and most probably it just creates more confusion for people who just enable all warnings (like it did for me). Remove the unaligned IP payload warning and the kconfig option. But leave the unaligned packet warning, it will be enabled with MAC80211_VERBOSE_DEBUG. Signed-off-by:
