In some cases it can be useful to change the MAC address of a virtual interface to something that's completely different from the EEPROM stored MAC address. In this case it is a bad idea to use the EEPROM MAC address for calculating the BSSID mask, as that would make it too wide. In one case a few devices have been observed to send ACKs for many packets on the channel not directed at them, which results in a neat Denial of Service attack on the channel. Signed-off-by:

This is called with spinlocks held so we have to use GFP_ATOMIC. It's the sc_pcu_lock in ath9k_stop() that's the issue. The call tree looks like this: ath9k_stop() ath_prepare_reset() ath_stoprecv() ath_flushrecv() ath_rx_tasklet() ath9k_dfs_process_phyerr() pd->add_pulse() => dpd_add_pulse() channel_detector_get() channel_detector_create() pri_detector_init() channel_detector_create() uses GFP_ATOMIC as well.

The DFS pattern detector was initially planned to reside on a higher layer and used generic pr_*() logging functions. Being part of ath9k, use ath_dbg() instead and make DFS log ouput selectable via ATH_DBG_DFS (0x20000) at runtime. This patch does not contain functional modifications. Signed-off-by:

Some cards on Ralink RT30xx chipset not have correctly TX_MIXER_GAIN value in them EEPROM/EFUSE. In this case, we must use default value, but always used EEPROM/EFUSE value. As result we have tranmitt power range from -10dBm to +6dBm instead 0dBm to +16dBm. Correctly value in EEPROM/EFUSE is one or more for RT3070 and two or more for other RT30xx chips. Tested on Canyon CNP-WF518N1 usb Wi-Fi dongle and Jorjin WN8020 usb embedded Wi-Fi module. Signed-off-by:

This rate causes an overflow in the extended rates IE's data rate field, with the overflowing bit setting the Basic Rate Set membership. This results in a bogus 8 Mpbs basic rate, making clients checking them refuse association. Since the rate is likely unused anyway (HT will yield better rates between supporting chips), we can just remove it. This fixes association from wpa_supplicant and Android 4.x and newer.

Samuel Ortiz <sameo@linux.intel.com> says: "This is the 2nd NFC pull request for 3.10. With this one we have: - A major pn533 update. The pn533 framing support has been changed in order to easily support all pn533 derivatives. For example we now support the ACR122 USB dongle. - An NFC MEI physical layer code factorization through the mei_phy NFC API. Both the microread and the pn544 drivers now use it. - LLCP aggregation support. This allows NFC p2p devices to send aggregated frames containing all sort of LLCP frames except SYMM and aggregation frames. - More LLCP socket options for getting the remote device link parameters. - Fixes for the LLCP socket option code added with the first pull request for 3.10. - Some support for LLCP corner cases like 0 length SDUs and general DISC (tagged with a 0,0 dsap ssap couple) handling. - RFKILL support for NFC."

-
Felix Fietkau authored
Allow rate control modules to pass a rate selection table to mac80211 and the driver. This allows drivers to fetch the most recent rate selection from the sta pointer for already buffered frames. This allows rate control to respond faster to sudden link changes and it is also a step towards adding minstrel_ht support to drivers like iwlwifi. When a driver sets IEEE80211_HW_SUPPORTS_RC_TABLE, mac80211 will not fill info->control.rates with rates from the rate table (to preserve explicit overrides by the rate control module). The driver then explicitly calls ieee80211_get_tx_rates to merge overrides from info->control.rates with defaults from the sta rate table. Signed-off-by:

Some protocols need a more reliable connection to complete successful in reasonable time. This patch adds a user-space API to indicate the wireless driver that a critical protocol is about to commence and when it is done, using nl80211 primitives NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP. There can be only on critical protocol session started per registered cfg80211 device. The driver can support this by implementing the cfg80211 callbacks .crit_proto_start() and .crit_proto_stop(). Examples of protocols that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the link can/should be made more reliable is up to the driver. Things to consider are avoid scanning, no multi-channel operations, and alter coexistence schemes. Reviewed-by:

The RCU docs used to state that rcu_barrier() included a wait for an RCU grace period; however the comments for rcu_barrier() as of commit f0a0e6f2... "rcu: Clarify memory-ordering properties of grace-period primitives" contradict this. So add back synchronize_{rcu,net}() to where they once were, but keep the rcu_barrier()s for the call_rcu() callbacks. Cc: stable <stable@vger.kernel.org> Signed-off-by:

Some driver implementations need to know whether mandatory admission control is required by the AP for some ACs. Add a parameter to the TX queue parameters indicating this. As there's currently no support for admission control in mac80211's AP implementation, it's only ever set for the client implementation. Signed-off-by:

In cfg80211_can_use_iftype_chan(), check for P2P Device first, and then for netdevs. This doesn't really change anything but makes the code a bit easier to read since it may not be obvious for everyone at first that a P2P device has no netdev. Signed-off-by: -

cfg80211_stop_p2p_device() requires the devlist_mtx to be held, but nl80211_stop_p2p_device() doesn't acquire it which is a locking error and causes a warning (when lockdep is enabled). Fix this. Signed-off-by: -

Most dump callbacks, including the scan results one, use the netdev to identify what to do, which is incorrect for the P2P_DEVICE support, it needs to be able to get the scan result from the wdev. Change all dumps to unify the code, but ones other than scan don't really support being executed on a wdev that has no netdev. Signed-off-by: -

Johan Hedberg authored
The local and remote features are organized by page number. Page 0 are the LMP features, page 1 the host features, and any pages beyond 1 features that future core specification versions may define. So far we've only had the first two pages and two separate variables has been convenient enough, however with the introduction of Core Specification Addendum 4 there are features defined on page 2. Instead of requiring the addition of a new variable each time a new page number is defined, this patch refactors the code to use a single table for the features. The patch needs to update both the hci_dev and hci_conn structures since there are macros that depend on the features being represented in the same way in both of them. Signed-off-by:

Some faulty non SSP devices send extended inquiry response during device discovery which is a violation of 2.1 specification. So for these devices we set SSP bit during acl connection initiation thinking that it is an SSP device. But for these devices, in remote host features event SSP supported bit will be off. But we are not clearing the SSP bit in that case and eventually SSP bit in conn flag will be incorrectly set for these devices. The software which has caused this issue is MecApp http://www.mecel.se/products/bluetooth/downloads/MecApp_download This patch does a workaround by clearing the SSP bit if it is not supported in remote host features event hcidump log ---------- < HCI Command: Inquiry (0x01|0x0001) plen 5 lap 0x9e8b33 len 4 num 0 > HCI Event: Command Status (0x0f) plen 4 Inquiry (0x01|0x0001) status 0x00 ncmd 1 > HCI Event: Extended Inquiry Result (0x2f) plen 255 bdaddr 00:1B:DC:05:B5:25 mode 1 clkoffset 0x3263 class 0x3c0000 rssi -77 Unknown type 0x42 with 8 bytes data Unknown type 0x1e with 2 bytes data > HCI Event: Inquiry Complete (0x01) plen 1 status 0x00 < HCI Command: Create Connection (0x01|0x0005) plen 13 bdaddr 00:1B:DC:05:B5:25 ptype 0xcc18 rswitch 0x01 clkoffset 0x0000 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 > HCI Event: Command Status (0x0f) plen 4 Create Connection (0x01|0x0005) status 0x00 ncmd 1 > HCI Event: Connect Complete (0x03) plen 11 status 0x00 handle 12 bdaddr 00:1B:DC:05:B5:25 type ACL encrypt 0x00 < HCI Command: Read Remote Supported Features (0x01|0x001b) plen 2 handle 12 > HCI Event: Command Status (0x0f) plen 4 Read Remote Supported Features (0x01|0x001b) status 0x00 ncmd 1 > HCI Event: Read Remote Supported Features (0x0b) plen 11 status 0x00 handle 12 Features: 0xff 0xff 0x8f 0x7e 0xd8 0x1f 0x5b 0x87 < HCI Command: Read Remote Extended Features (0x01|0x001c) plen 3 handle 12 page 1 > HCI Event: Command Status (0x0f) plen 4 Read Remote Extended Features (0x01|0x001c) status 0x00 ncmd 1 > HCI Event: Page Scan Repetition Mode Change (0x20) plen 7 bdaddr 00:1B:DC:05:B5:25 mode 1 > HCI Event: Max Slots Change (0x1b) plen 3 handle 12 slots 5 > HCI Event: Read Remote Extended Features (0x23) plen 13 status 0x00 handle 12 page 1 max 0 Features: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 < HCI Command: Remote Name Request (0x01|0x0019) plen 10 bdaddr 00:1B:DC:05:B5:25 mode 2 clkoffset 0x0000 > HCI Event: Command Status (0x0f) plen 4 Remote Name Request (0x01|0x0019) status 0x00 ncmd 1 > HCI Event: Remote Name Req Complete (0x07) plen 255 status 0x00 bdaddr 00:1B:DC:05:B5:25 name 'Bluetooth PTS Radio v4' < HCI Command: Authentication Requested (0x01|0x0011) plen 2 handle 12 > HCI Event: Command Status (0x0f) plen 4 Authentication Requested (0x01|0x0011) status 0x00 ncmd 1 > HCI Event: Link Key Request (0x17) plen 6 bdaddr 00:1B:DC:05:B5:25 < HCI Command: Link Key Request Negative Reply (0x01|0x000c) plen 6 bdaddr 00:1B:DC:05:B5:25 > HCI Event: Command Complete (0x0e) plen 10 Link Key Request Negative Reply (0x01|0x000c) ncmd 1 status 0x00 bdaddr 00:1B:DC:05:B5:25 > HCI Event: PIN Code Request (0x16) plen 6 bdaddr 00:1B:DC:05:B5:25 Signed-off-by:

Since Stanislaw's patches, when suspending while connected, cfg80211 will disconnect. This causes the AP station to be removed, which uses call_rcu() to clean up. Due to needing process context, this queues a work struct on the mac80211 workqueue. This will warn and fail when already suspended, which can happen if the rcu call doesn't happen quickly. To fix this, replace the synchronize_net() which is really just synchronize_rcu_expedited() with rcu_barrier(), which unlike synchronize_rcu() waits until RCU callback have run and thus avoids this issue. In theory, this can even happen without Stanislaw's change to disconnect on suspend since userspace might disconnect just before suspending, though then it's unlikely that the call_rcu() will be delayed long enough.

According to the specifications, data output reports must be sent on the interrupt channel. See also usbhid implementation. Sending these reports on the control channel breaks newer Wii Remotes. Note that this will make output reports asynchronous. However, that's how hid_output_raw_report() is supposed to work with HID_OUTPUT_REPORT as report type. There are no responses to output reports.

If a device is registered as HID device, it is always in Report-Mode. Therefore, we must not send Boot-Protocol messages on hidinput_input_event() callbacks. This confuses devices and may cause disconnects on protocol errors. We disable the hidinput_input_event() callback for now. We can implement it properly later, but lets first fix the current code by disabling it. Signed-off-by:
