* rtlwifi: Fix leak of skb when processing C2H_BT_INFOLarry Finger2018-12-131-0/+1
| | | | | | | | | | | | | | | | | With commit 0a9f8f0a1ba9 ("rtlwifi: fix btmpinfo timeout while processing C2H_BT_INFO"), calling rtl_c2hcmd_enqueue() with rtl_c2h_fast_cmd() true, the routine returns without freeing that skb, thereby leaking it. This issue has been discussed at https://github.com/lwfinger/rtlwifi_new/issues/401 and the fix tested there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PixArt OEM mice are known for disconnecting every minute in runlevel 1 or 3 if they are not always polled. So add quirk ALWAYS_POLL for two Primax mice as well. 0x4e22 is the Dell MS111-P and 0x4d0f is the unbranded HP Portia mouse HP 697738-001. Both were built until approx. 2014. Those were the standard mice from those vendors and are still around - even as new old stock.

| * HID: i2c-hid: Disable runtime PM for LG touchscreenKai-Heng Feng2018-11-192-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | LG touchscreen (1fd2:8001) stops working after reboot: [ 4.859153] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 4.936070] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 9.948224] i2c_hid i2c-SAPS2101:00: failed to reset device. The device in question stops working after receives SLEEP, ON, SLEEP commands in a short period. The scenario is like this: - Once the desktop session closes, it also closed the hid device, so the device gets runtime suspended and receives a SLEEP command. - Before calling shutdown callback, it gets runtime resumed and received an ON command. - In the shutdown callback, it receives another SLEEP command. I failed to find a reliable interval between ON/SLEEP commands that can make it work, so let's simply disable runtime PM for the device.

| * HID: steam: remove input device when a hid client is running.Rodrigo Rivas Costa2018-11-191-64/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when a HID client such as the Steam Client was running, this driver disabled its input device to avoid doubling the input events. While it worked mostly fine, some games got confused by the idle gamepad, and switched to two player mode, or asked the user to choose which gamepad to use. Other games just crashed, probably a bug in Unity [1]. With this commit, when a HID client starts, the input device is removed; when the HID client ends the input device is recreated.

| * Revert "HID: uhid: use strlcpy() instead of strncpy()"David Herrmann2018-11-191-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 336fd4f5f25157e9e8bd50e898a1bbcd99eaea46. Please note that `strlcpy()` does *NOT* do what you think it does. strlcpy() *ALWAYS* reads the full input string, regardless of the 'length' parameter. That is, if the input is not zero-terminated, strlcpy() will *READ* beyond input boundaries. It does this, because it always returns the size it *would* copy if the target was big enough, not the truncated size it actually copied. The original code was perfectly fine. The hid device is zero-initialized and the strncpy() functions copied up to n-1 characters. The result is always zero-terminated this way. This is the third time someone tried to replace strncpy with strlcpy in this function, and gets it wrong. I now added a comment that should at least make people reconsider.

| * HID: uhid: forbid UHID_CREATE under KERNEL_DS or elevated privilegesEric Biggers2018-11-191-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a UHID_CREATE command is written to the uhid char device, a copy_from_user() is done from a user pointer embedded in the command. When the address limit is KERNEL_DS, e.g. as is the case during sys_sendfile(), this can read from kernel memory. Alternatively, information can be leaked from a setuid binary that is tricked to write to the file descriptor. Therefore, forbid UHID_CREATE in these cases. No other commands in uhid_char_write() are affected by this bug and UHID_CREATE is marked as "obsolete", so apply the restriction to UHID_CREATE only rather than to uhid_char_write() entirely. Thanks to Dmitry Vyukov for adding uhid definitions to syzkaller and to Jann Horn for commit 9da3f2b740544 ("x86/fault: BUG() when uaccess helpers fault on kernel addresses"), allowing this bug to be found.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Motorola/Zebra Symbol DS4308-HD is a handheld USB barcode scanner which does not have a battery, but reports one anyway that always has capacity 2. Let's apply the IGNORE quirk to prevent it from being treated like a power supply so that userspaces don't get confused that this accessory is almost out of power and warn the user that they need to charge their wired barcode scanner.

We should do this when enabling/changed to a new port. But it doesn't make sense to do it when a port is disabled. On the other hand, when we set mcast_rejoin_count to 2, and do a failover, team_port_disable() will increase mcast_rejoin.count_pending to 2 and then team_port_enable() will increase mcast_rejoin.count_pending to 4. We will send 4 mcast rejoin messages at latest, which will make user confused. The same with notify_peers.count. Fix it by deleting team_notify_peers() and team_mcast_rejoin() in team_port_disable().

However, this condition causes kerenl hang in the following case. When the user requests to disable the network device, kernel will clear the bit __LINK_STATE_START from the dev->state and then call the driver's ndo_stop function. Network device interrupts are not blocked during this process. If an interrupt occurs between clearing __LINK_STATE_START and stopping network device, kernel cannot disable the interrupts due to the condition "netif_running(netdev)" in the ISR. Hence, kernel will hang due to the continuous interruption of the network device. In order to solve the above problem, the interrupts of the network device should always be disabled in the ISR without being restricted by the condition "netif_running(netdev)".

The driver can feed the firmware with previous knowledge that was kept in the driver, but the firmware may still not update its internal tables. This happens when we start a BSS interface, and then the firmware can change the regulatory tables based on our location and it'll use more lenient, location specific rules. Then, if the firmware is shut down (when the interface is brought down), and then an AP interface is created, the firmware will forget the country specific rules. The host will think that we are in a certain country that may allow channels and will try to teach the firmware about our location, but the firmware may still not allow to drop the world wide limitations and apply country specific rules because it was just re-started. In this case, the firmware will reply with MCC_RESP_ILLEGAL to the MCC_UPDATE_CMD. In that case, iwlwifi needs to let the upper layers (cfg80211 / hostapd) know that the channel list they know about has been updated.

In virtualization setups where the port mtu can be larger than the vf mtu, if received packet is bigger than MTU, it won't be dropped by HW on too small receive WQE. If we use linear SKB in striding RQ, since each stride has room for mtu size payload and skb info, an oversized packet can lead to crash for crossing allocated page boundary upon the call to build_skb. So driver needs to check packet size and drop it. Introduce new SW rx counter, rx_oversize_pkts_sw_drop, which counts the number of packets dropped by the driver for being too large. As a new field is added to the RQ struct, re-open the channels whenever this field is being used in datapath (i.e., in the case of linear Striding RQ).
