This was introduced by the commit cb3b3152 Because of this, l2cap info rsp is not handled and command reject is sent. > ACL data: handle 11 flags 0x02 dlen 16 L2CAP(s): Info rsp: type 2 result 0 Extended feature mask 0x00b8 Enhanced Retransmission mode Streaming mode FCS Option Fixed Channels < ACL data: handle 11 flags 0x00 dlen 10 L2CAP(s): Command rej: reason 0 Command not understood Cc: stable@vger.kernel.org Signed-off-by:

Since my commit 3713b4e3 ("nl80211: allow splitting wiphy information in dumps"), nl80211_dump_wiphy() uses the global nl80211_fam.attrbuf for parsing the incoming data. This wouldn't be a problem if it only did so on the first dump iteration which is locked against other commands in generic netlink, but due to space constraints in cb->args (the needed state doesn't fit) I decided to always parse the original message. That's racy though since nl80211_fam.attrbuf could be used by some other parsing in generic netlink concurrently. For now, fix this by allocating a separate parse buffer (it's a bit too big for the stack, currently 1448 bytes on 64-bit). For -next, I'll change the code to parse into the global buffer in the first round only and then allocate a smaller buffer to keep the data in cb->args. Reported-by:

There is currently a race condition in the btmrvl_remove_card() which is causing hangs on suspend for OLPC. When the race occurs, kthread_stop() never returns. The problem is that btmrvl_service_main_thread() calls kthread_should_stop() and then does a fair number of things before restarting the loop and sleeping. If the thread gets stopped after kthread_should_stop() is checked, but before the sleep happens, the thread will go to sleep and won't necessarily be woken up. Move the kthread_should_stop() check into a race-free place. Signed-off-by:

Even though the HCI_Delete_Stored_Link_Key command is mandatory for 1.1 and later controllers some controllers do not seem to support it properly as was witnessed by one Broadcom based controller: < HCI Command: Delete Stored Link Key (0x03|0x0012) plen 7 bdaddr 00:00:00:00:00:00 all 1 > HCI Event: Command Complete (0x0e) plen 4 Delete Stored Link Key (0x03|0x0012) ncmd 1 status 0x11 deleted 0 Error: Unsupported Feature or Parameter Value Luckily this same controller also doesn't list the command in its supported commands bit mask (counting from 0 bit 7 of octet 6): < HCI Command: Read Local Supported Commands (0x04|0x0002) plen 0 > HCI Event: Command Complete (0x0e) plen 68 Read Local Supported Commands (0x04|0x0002) ncmd 1 status 0x00 Commands: ffffffffffff1ffffffffffff30fffff3f Therefore, it makes sense to move sending of HCI_Delete_Stored_Link_Key to after receiving the supported commands response and to only send it if its respective bit in the mask is set. The downside of this is that we no longer send the HCI_Delete_Stored_Link_Key command for Bluetooth 1.1 controllers since HCI_Read_Local_Supported_Command was introduced in version 1.2, but this is an acceptable penalty as the command in question shouldn't affect critical behavior.

My change: commit cee2c731 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Fri Oct 5 13:44:09 2012 +0200 rt2800: use BBP_R1 for setting tx power unfortunately does not work well with RT5390 and RT3290 chips as they require different temperature compensation TX power settings (TSSI tuning). Since that commit make wireless connection very unstable on those chips, restore previous behavior to fix regression. Once we implement proper TSSI tuning on 5390/3290 we can restore back setting TX power by BBP_R1 register for those chips. Reported-and-tested-by:

This patch fixes a regression introduced by: commit 6da3b6c4 Author: Hauke Mehrtens <hauke@hauke-m.de> Date: Sun Mar 24 01:45:52 2013 +0100 brcmsmac: remove brcms_bss_cfg->associated The regression behaviour was described on mailing list. http://mid.gmane.org/5197DC4F.7030503@broadcom.com: "On laptop I installed kernel with brcmsmac compiled as module. It comes up and associates during boot, but after logging in there is no connectivity. Triggering reassoc gives connectivity for some time, but after a while (1-2 min) it stops." Before the mentioned commit the return value of the function brcms_c_ps_allowed() was always false, which is desired behaviour as power-save is not supported at the moment. Therefor, the function is changed to just return false instead of simply reverting the mentioned commit. Bug: 58471 <https://bugzilla.kernel.org/show_bug.cgi?id=58471> Signed-off-by:

Since driver does not use control.rates[0].count, we have never set that variable. But currently, after rate control API rewrite, this is required by mac80211. Otherwise legacy rates control does not work and we transmit always at 1Mbit/s on pre 11n networks. Signed-off-by:

The module parameter "fwpostfix" is userspace controllable, unfiltered, and is used to define the firmware filename. b43_do_request_fw() populates ctx->errors[] on error, containing the firmware filename. b43err() parses its arguments as a format string. For systems with b43 hardware, this could lead to a uid-0 to ring-0 escalation. CVE-2013-2852 Signed-off-by:

The ath9k rate control algorithm has various architectural issues that make it a poor fit in scenarios like congested environments etc. An example: https://bugzilla.redhat.com/show_bug.cgi?id=927191 Change the default to minstrel which is more robust in such cases. The ath9k RC code is left in the driver for now, maybe it can be removed altogether later on.

Almost all the DMA issues which have plagued ath9k (in station mode) for years are related to PS. Disabling PS usually "fixes" the user's connection stablility. Reports of DMA problems are still trickling in and are sitting in the kernel bugzilla. Until the PS code in ath9k is given a thorough review, disbale it by default. The slight increase in chip power consumption is a small price to pay for improved link stability. Cc: stable@vger.kernel.org Signed-off-by:

For example, when testing P2P, the mode is '8' (P2P_CLIENT) so the code accesses data beyond the bounds of the bss_modes[] array which causes the panic. Fix this by updating bss_modes[] to support the current list of modes and adding a check to prevent the out-of-bounds access from occuring in the future when more modes are added. Signed-off-by:

This patch fixes the missing response by adding a new mgmt_set_powered_failed function that's used to indicate a power on failure to mgmt. Since a situation with the device being rfkilled may require special handling in user space the patch uses a new dedicated mgmt status code for this. Signed-off-by:

There has been code in place to check that the L2CAP length header matches the amount of data received, but many PDU handlers have not been checking that the data received actually matches that expected by the specific PDU. This patch adds passing the length header to the specific handler functions and ensures that those functions fail cleanly in the case of an incorrect amount of data. Signed-off-by:

LE-only controllers do not support extended features so any kind of host feature bit checks do not make sense for them. This patch fixes code used for both single-mode (LE-only) and dual-mode (BR/EDR/LE) to use the HCI_LE_ENABLED flag instead of the "Host LE supported" feature bit for LE support tests. Signed-off-by:

Since driver does not use control.rates[0].count, we have never set that variable. But currently, after rate control API rewrite, this is required by mac80211. Otherwise legacy rates control does not work and we transmit always at 1Mbit/s on pre 11n networks. [same fix as for iwlegacy, thanks Stanislaw!] Signed-off-by:

When a CAC is running and stop_ap is called (e.g. when hostapd is killed while performing CAC), the CAC must be aborted immediately. Otherwise ieee80211_stop_ap() will try to stop it when it's too late - wdev->channel is already NULL and the abort event can not be generated. Signed-off-by:

There are some APs, notably 2G/3G/4G Wifi routers, specifically the "Onda PN51T", "Vodafone PocketWiFi 2", "ZTE MF60" and a similar T-Mobile branded device [1] that erroneously don't include all the needed information in (re)association response frames. Work around this by assuming the information is the same as it was in the beacon or probe response and using the data from there instead. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=58881. [1] https://bbs.archlinux.org/viewtopic.php?pid=1277305 Note that this requires marking the first ieee802_11_parse_elems() argument const, otherwise we'd get a compiler warning.

If the opmode modules aren't modular, there's no point in printing an error message that request_module() failed. This will happen because the probe runs during iwlwifi's init and the opmode is only added during its init. Reported-by:
