commit b8b8b16352cd90c6083033fd4487f04fae935c18 upstream. In commit 40b368af4b75 ("rtlwifi: Fix alignment issues"), the read of REG_DBI_READ was changed from 16 to 8 bits. For unknown reasonsi this change results in reduced stability for the wireless connection. This regression was located using bisection.

2017-10-27brcmsmac: make some local variables 'static const' to reduce stack sizeArnd Bergmann1-100/+97
commit c503dd38f850be28867ef7a42d9abe5ade81a9bd upstream. With KASAN and a couple of other patches applied, this driver is one of the few remaining ones that actually use more than 2048 bytes of kernel stack: broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy_gainctrl': broadcom/brcm80211/brcmsmac/phy/phy_n.c:16065:1: warning: the frame size of 3264 bytes is larger than 2048 bytes [-Wframe-larger-than=] broadcom/brcm80211/brcmsmac/phy/phy_n.c: In function 'wlc_phy_workarounds_nphy': broadcom/brcm80211/brcmsmac/phy/phy_n.c:17138:1: warning: the frame size of 2864 bytes is larger than 2048 bytes [-Wframe-larger-than=] Here, I'm reducing the stack size by marking as many local variables as 'static const' as I can without changing the actual code. This is the first of three patches to improve the stack usage in this driver. It would be good to have this backported to stabl kernels to get all drivers in 'allmodconfig' below the 2048 byte limit so we can turn on the frame warning again globally, but I realize that the patch is larger than the normal limit for stable backports. The other two patches do not need to be backported.

2017-10-27brcmfmac: Add check for short event packetsKevin Cernekee1-1/+2
commit dd2349121bb1b8ff688c3ca6a2a0bea9d8c142ca upstream. The length of the data in the received skb is currently passed into brcmf_fweh_process_event() as packet_len, but this value is not checked. event_packet should be followed by DATALEN bytes of additional event data. Ensure that the received packet actually contains at least DATALEN bytes of additional data, to avoid copying uninitialized memory into event->data.

commit 9de981f507474f326e42117858dc9a9321331ae5 upstream. In struct ieee80211_tx_info, control.vif pointer and rate_driver_data[0] falls on the same place, depending on the union usage. During the whole TX process, the union is referred to as a control struct, which holds the vif that is later used in the tx flow, especially in order to derive the used tx power. Referring direcly to rate_driver_data[0] and assigning a value to it, overwrites the vif pointer, hence making all later references irrelevant. Moreover, rate_driver_data[0] isn't used later in the flow in order to retrieve the channel that it is pointing to.

2017-09-27wcn36xx: Introduce mutual exclusion of fw configurationBjorn Andersson2-2/+53
commit 39efc7cc7ccf82d1cd946580cdb70760f347305a upstream. As the association status changes the driver needs to configure the hardware. This is done based on information in the "sta" acquired by ieee80211_find_sta(), which requires the caller to ensure that the "sta" is valid while its being used; generally by entering an rcu read section. But the operations acting on the "sta" has to communicate with the firmware and may therefor sleep, resulting in the following report: [ 31.418190] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:238 [ 31.425919] in_atomic(): 0, irqs_disabled(): 0, pid: 34, name: kworker/u8:1 [ 31.434609] CPU: 0 PID: 34 Comm: kworker/u8:1 Tainted: G W 4.12.0-rc4-next-20170607+ #993 [ 31.441002] Hardware name: Qualcomm Technologies, Inc.

2017-09-09mwifiex: correct channel stat buffer overflowsBrian Norris2-1/+7
commit 4b5dde2d6234ff5bc68e97e6901d1f2a0a7f3749 upstream. mwifiex records information about various channels as it receives scan information. It does this by appending to a buffer that was sized to the max number of supported channels on any band, but there are numerous problems: (a) scans can return info from more than one band (e.g., both 2.4 and 5 GHz), so the determined "max" is not large enough (b) some firmware appears to return multiple results for a given channel, so the max *really* isn't large enough (c) there is no bounds checking when stashing these stats, so problems (a) and (b) can easily lead to buffer overflows Let's patch this by setting a slightly-more-correct max (that accounts for a combination of both 2.4G and 5G bands) and adding a bounds check when writing to our statistics buffer. Due to problem (b), we still might not properly report all known survey information (e.g., with "iw <dev> survey dump"), since duplicate results (or otherwise "larger than expected" results) will cause some truncation. But that's a problem for a future bugfix. (And because of this known deficiency, only log the excess at the WARN level, since that isn't visible by default in this driver and would otherwise be a bit too noisy.)

commit f35a7f91f66af528b3ee1921de16bea31d347ab0 upstream. The rx ring buffers are added to a hash table if firmware support full rx reorder. If the full rx reorder support flag is not set before allocating the rx ring buffers, none of the buffers are added to the hash table. There is a race condition between rx ring refill and rx buffer replenish from napi poll. The interrupts are enabled in hif start, before the rx ring is refilled during init. We replenish buffers from napi poll due to the interrupts which get enabled after hif start. Hence before the entire rx ring is refilled during the init, the napi poll replenishes a few buffers in steps of 100 buffers per attempt. During this rx ring replenish from napi poll, the rx reorder flag has not been set due to which the replenished buffers are not added to the hash table Set the rx full reorder support flag before we allocate the rx ring buffer to avoid the memory leak.

2017-08-09iwlwifi: mvm: send delba upon rx ba session timeoutNaftali Goldstein1-2/+2
When an RX block-ack session times out, the firmware, which offloads RX reordering but not the BA session negotiation, stops the session but doesn't send a DELBA. This causes the the session to remain active in the remote device, so no more BA sessions will be established, causing a severe throughput degradation due to the lack of aggregation. Use the new ieee80211_rx_ba_timer_expired API when the ba session timer expires, since this will tear down the ba session and also send a delba. The previous API used is intended for drivers that offload the addba/delba negotiation, but not the rx reordering, while our driver does the opposite. This patch depends on "mac80211: add api to start ba session timer expired flow". Signed-off-by: Naftali Goldstein <naftali.goldstein@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-08-09iwlwifi: mvm: don't WARN when a legit race happens in A-MPDUEmmanuel Grumbach1-4/+6
When we start an Rx A-MPDU session, we first get the AddBA request, then we send an ADD_STA command to the firmware that will reply with a BAID which is a hardware resource that tracks the BA session. This BAID will appear on each and every frame that we get from the firwmare until the A-MPDU session is torn down. In the Rx path, we look at this BAID to manage the reordering buffer. This flow is inherently racy since the hardware will start to put the BAID in the frames it receives even if the firmware hasn't sent the response to the ADD_STA command. This basically means that the driver can get frames with a valid BAID that it doesn't know yet. When that happens, the driver used to WARN. Fix this by simply not WARN in this case. When the driver will know abou the BAID, it will initialise the relevant states and the next frame with a valid BAID will refresh them.

2017-08-09iwlwifi: mvm: start mac queues when deferred tx frames are purgedAvraham Stern1-1/+11
In AP mode, if a station is removed just as it is adding a new stream, the queue in question will remain stopped and no more TX will happen in this queue, leading to connection failures and other problems. This is because under DQA, when tx is deferred because a queue needs to be allocated, the mac queue for that TID is stopped until the new stream is added. If at this point the station that this stream belongs to is removed, all the deferred tx frames are purged, but the mac queue is not restarted. As a result, all following tx on this queue will not be transmitted. Fix this by starting the relevant mac queues when the deferred tx frames are purged.

In particular, in AP mode, clients are added upon receival of an auth request, at which point there's no knowledge of the client's smps mode. When the assoc request arrives, the add_sta command is resent to modify the station parameters. At this point the driver knows the smps mode, but since the corresponding bit in the mask is not set, the fw doesn't update this field so there's no rts protection for mimo.

2017-08-01iwlwifi: split the regulatory rules when the bandwidth flags require itEmmanuel Grumbach1-8/+11
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.

2017-07-21iwlwifi: mvm: defer setting IWL_MVM_STATUS_IN_HW_RESTARTJohannes Berg3-4/+12
A hardware/firmware error may happen at any point in time. In particular, it might happen while mac80211 is in the middle of a flow. We observed the following situation: * mac80211 is in authentication flow, in ieee80211_prep_connection() * iwlwifi firmware crashes, but no error can be reported at this precise point (mostly because the driver method is void, but even if it wasn't we'd just shift to a race condition) * mac80211 continues the flow, trying to add the AP station * iwlwifi has already set its internal restart flag, and so thinks that adding the station is part of the restart and already set up, so it uses the information that's supposed to already be in the struct This can happen with any flow in mac80211 and with any information we try to preserve across hardware restarts. To fix this, only set a new HW_RESTART_REQUESTED flag and translate that to IN_HW_RESTART once mac80211 actually starts the restart by calling our start() method. As a consequence, any mac80211 flow in progress at the time of the restart will properly finish (certainly with errors), before the restart is attempted.

iwl_trace_data is somewhat confusing. It returns a bool that tells if the payload of the skb should be added to the tx_data event. If it returns false, then the payload of the skb is added to the tx event. The purpose is to be able to start tracing with -e iwlwifi and record non-data packets only which saves bandwidth. Since EAPOLs are important, seldom and not real data packet (despite being WiFi data packets), they are included in tx event and thus iwl_trace_data returns false on those. This last part was buggy, and because of that, all the data packets were included in the tx event. Fix that.

For example the stations don't get added properly to mvm->fw_id_to_mac_id. Mac80211 tries to stop A-MPDU upon reconfig but in case of a firmware crash we will bail out fairly early and in the end, we won't delete the A-MPDU Rx timeout.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the big driver core update for 4.13-rc1. The large majority of this is a lot of cleanup of old fields in the driver core structures and their remaining usages in random drivers. All of those fixes have been reviewed by the various subsystem maintainers. There's also some small firmware updates in here, a new kobject uevent api interface that makes userspace interaction easier, and a few other minor things. All of these have been in linux-next for a long while with no reported issues" * tag 'driver-core-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (56 commits) arm: mach-rpc: ecard: fix build error zram: convert remaining CLASS_ATTR() to CLASS_ATTR_RO() driver-core: remove struct bus_type.dev_attrs powerpc: vio_cmo: use dev_groups and not dev_attrs for bus_type powerpc: vio: use dev_groups and not dev_attrs for bus_type USB: usbip: convert to use DRIVER_ATTR_RW s390: drivers: convert to use DRIVER_ATTR_RO/WO platform: thinkpad_acpi: convert to use DRIVER_ATTR_RO/RW pcmcia: ds: convert to use DRIVER_ATTR_RO wireless: ipw2x00: convert to use DRIVER_ATTR_RW net: ehea: convert to use DRIVER_ATTR_RO net: caif: convert to use DRIVER_ATTR_RO TTY: hvc: convert to use DRIVER_ATTR_RW PCI: pci-driver: convert to use DRIVER_ATTR_WO IB: nes: convert to use DRIVER_ATTR_RW HID: hid-core: convert to use DRIVER_ATTR_RO and drv_groups arm: ecard: fix dev_groups patch typo tty: serdev: use dev_groups and not dev_attrs for bus_type sparc: vio: use dev_groups and not dev_attrs for bus_type hid: intel-ish-hid: use dev_groups and not dev_attrs for bus_type ...
