2017-01-03xhci: Fix race related to abort operationOGAWA Hirofumi3-80/+90
Current abort operation has race. xhci_handle_command_timeout() xhci_abort_cmd_ring() xhci_write_64(CMD_RING_ABORT) xhci_handshake(5s) do { check CMD_RING_RUNNING udelay(1) ... COMP_CMD_ABORT event COMP_CMD_STOP event xhci_handle_stopped_cmd_ring() restart cmd_ring CMD_RING_RUNNING become 1 again } while () return -ETIMEDOUT xhci_write_64(CMD_RING_ABORT) /* can abort random command */ To do abort operation correctly, we have to wait both of COMP_CMD_STOP event and negation of CMD_RING_RUNNING. But like above, while timeout handler is waiting negation of CMD_RING_RUNNING, event handler can restart cmd_ring. So timeout handler never be notice negation of CMD_RING_RUNNING, and retry of CMD_RING_ABORT can abort random command (BTW, I guess retry of CMD_RING_ABORT was workaround of this race). To fix this race, this moves xhci_handle_stopped_cmd_ring() to xhci_abort_cmd_ring(). And timeout handler waits COMP_CMD_STOP event. At this point, timeout handler is owner of cmd_ring, and safely restart cmd_ring by using xhci_handle_stopped_cmd_ring(). [FWIW, as bonus, this way would be easily extend to add CMD_RING_PAUSE operation] [locks edited as patch is rebased on other locking fixes -Mathias] Signed-off-by: OGAWA Hirofumi <[email protected]> Signed-off-by: Mathias Nyman <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2017-01-03usb: xhci: hold lock over xhci_abort_cmd_ring()Lu Baolu1-4/+9
In command timer function, xhci_handle_command_timeout(), xhci->lock is unlocked before call into xhci_abort_cmd_ring(). This might cause race between the timer function and the event handler. The xhci_abort_cmd_ring() function sets the CMD_RING_ABORT bit in the command register and polling it until the setting takes effect. A stop command ring event might be handled between writing the abort bit and polling for it. The event handler will restart the command ring, which causes the failure of polling, and we ever believed that we failed to stop it. As a bonus, this also fixes some issues of calling functions without locking in xhci_handle_command_timeout().

2017-01-03xhci: Handle command completion and timeout raceMathias Nyman1-1/+5
If we get a command completion event at the same time as the command timeout work starts on another cpu we might end up aborting the wrong command. If the command completion takes the xhci lock before the timeout work, it will handle the command, pick the next command, mark it as current_cmd, and re-queue the timeout work. When the timeout work finally gets the lock It will start aborting the wrong command. This case can be resolved by checking if the timeout work is pending inside the timeout function itself. A new timeout work can only be pending if the command completed and a new command was queued. If there are no more commands pending then command completion will set the current_cmd to NULL, which is already handled in the timeout work.

2017-01-03usb: xhci: fix possible wild pointerLu Baolu1-5/+11
handle_cmd_completion() frees a command structure which might be still referenced by xhci->current_cmd. This might cause problem when xhci->current_cmd is accessed after that. A real-life case could be like this. The host takes a very long time to respond to a command, and the command timer is fired at the same time when the command completion event arrives. The command completion handler frees xhci->current_cmd before the timer function can grab xhci->lock. Afterward, timer function grabs the lock and go ahead with checking and setting members of xhci->current_cmd.

2017-01-03usb: return error code when platform_get_irq failsPan Bian1-1/+3
In function xhci_mtk_probe(), variable ret takes the return value. Its value should be negative on failures. However, when the call to function platform_get_irq() fails, it does not set the error code, and 0 will be returned. 0 indicates no error. As a result, the callers of function xhci_mtk_probe() will not be able to detect the error. This patch fixes the bug by assigning the return value of platform_get_irq() to variable ret if it fails.

2017-01-03usb: xhci: fix return value of xhci_setup_device()Lu Baolu1-1/+3
xhci_setup_device() should return failure with correct error number when xhci host has died, removed or halted. During usb device enumeration, if usb host is not accessible (died, removed or halted), the hc_driver->address_device() should return a corresponding error code to usb core. But current xhci driver just returns success. This misleads usb core to continue the enumeration by reading the device descriptor, which will result in failure, and users will get a misleading message like "device descriptor read/8, error -110".

2017-01-03benet: stricter vxlan offloading check in be_features_checkSabrina Dubroca1-1/+3
When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured.

Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on.

2017-01-02ACPI / scan: Prefer devices without _HID/_CID for _ADR matchingRafael J. Wysocki1-1/+9
The way acpi_find_child_device() works currently is that, if there are two (or more) devices with the same _ADR value in the same namespace scope (which is not specifically allowed by the spec and the OS behavior in that case is not defined), the first one of them found to be present (with the help of _STA) will be returned. This covers the majority of cases, but is not sufficient if some of the devices in question have a _HID (or _CID) returning some valid ACPI/PNP device IDs (which is disallowed by the spec) and the ASL writers' expectation appears to be that the OS will match devices without a valid ACPI/PNP device ID against a given bus address first. To cover this special case as well, modify find_child_checks() to prefer devices without ACPI/PNP device IDs over devices that have them.

This one took a while to get tested on 24bit parts. Definitely one for stable asap as the bug broke quite a few parts. - lis3lv02 needs a data alignment bit set and the scaling was wrong. * ti_am335x - depend on HAS_DMA

2017-01-02HID: sensor-hub: Move the memset to sensor_hub_get_feature()Srinivas Pandruvada1-1/+2
While applying patch d443a0aa3a29: "HID: hid-sensor-hub: clear memory to avoid random data", there was some issues in applying correct version of the patch. This resulted in the breakage of sensor functions as all request like power-up will be reset by the memset() in the function sensor_hub_set_feature(). The reset of caller buffer should be in the function sensor_hub_get_feature(), not in the sensor_hub_set_feature().

2017-01-02drm/i915: Move number of scalers initialization to runtime initNabendu Maiti3-17/+17
In future patches, we require greater flexibility in describing the number of scalers available on each CRTC. To ease that transition we move the current assignment to intel_device_info. Scaler structure initialisation is done if scaler is available on the CRTC. Gen9 check is not required as on depending upon numbers of scalers we initialize scalers or return without doing anything in skl_init_scalers. v3: Changed skl_init_scaler to intel_crtc_init_scalers v2: Added Chris's comments.

With gcc 4.1.2: drivers/usb/serial/f81534.c: In function ‘f81534_port_probe’: drivers/usb/serial/f81534.c:1250: warning: comparison is always false due to limited range of data type f81534_logic_to_phy_port() may return a negative error value, which is ignored by assigning it to u8 f81534_port_private.phy_num. Use an intermediate variable of type int to fix this. While at it, forward the actual error code instead of converting it to -ENODEV, and drop the useless check for F81534_NUM_PORT, as the callee always returns a valid port number in case of success.

2017-01-02usb: gadget: udc: core: fix return code of usb_gadget_probe_driver()Felix Hädicke1-1/+5
This fixes a regression which was introduced by commit f1bddbb, by reverting a small fragment of commit 855ed04. If the following conditions were met, usb_gadget_probe_driver() returned 0, although the call was unsuccessful: 1. A particular UDC was specified by thge gadget driver (using member "udc_name" of struct usb_gadget_driver). 2. The UDC with this name is available. 3. Another gadget driver is already bound to this gadget. 4. The gadget driver has the "match_existing_only" flag set. In this case, the return code variable "ret" is set to 0, the return code of a strcmp() call (to check for the second condition). This also fixes an oops which could occur in the following scenario: 1. Two usb gadget instances were configured using configfs. 2. The first gadget configuration was bound to a UDC (using the configfs attribute "UDC"). 3. It was tried to bind the second gadget configuration to the same UDC in the same way. This operation was then wrongly reported as being successful. 4. The second gadget configuration's "UDC" attribute is cleared, to unbind the (not really bound) second gadget configuration from the UDC. <BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff94f5e5e9>] __list_del_entry+0x29/0xc0 PGD 41b4c5067 PUD 41a598067 PMD 0 Oops: 0000 [#1] SMP Modules linked in: cdc_acm usb_f_fs usb_f_serial usb_f_acm u_serial libcomposite configfs dummy_hcd bnep intel_rapl x86_pkg_temp_thermal intel_powerclamp coretemp kvm_intel kvm snd_hda_codec_hdmi irqbypass crct10dif_pclmul crc32_pclmul ghash_clmulni_intel aesni_intel aes_x86_64 lrw gf128mul glue_helper ablk_helper cryptd snd_hda_codec_realtek snd_hda_codec_generic serio_raw uvcvideo videobuf2_vmalloc btusb snd_usb_audio snd_hda_intel videobuf2_memops btrtl snd_hda_codec snd_hda_core snd_usbmidi_lib btbcm videobuf2_v4l2 btintel snd_hwdep videobuf2_core snd_seq_midi bluetooth snd_seq_midi_event videodev xpad efi_pstore snd_pcm_oss rfkill joydev media crc16 ff_memless snd_mixer_oss snd_rawmidi nls_ascii snd_pcm snd_seq snd_seq_device nls_cp437 mei_me snd_timer vfat sg udc_core lpc_ich fat efivars mfd_core mei snd soundcore battery nuvoton_cir rc_core evdev intel_smartconnect ie31200_edac edac_core shpchp tpm_tis tpm_tis_core tpm parport_pc ppdev lp parport efivarfs autofs4 btrfs xor raid6_pq hid_logitech_hidpp hid_logitech_dj hid_generic usbhid hid uas usb_storage sr_mod cdrom sd_mod ahci libahci nouveau i915 crc32c_intel i2c_algo_bit psmouse ttm xhci_pci libata scsi_mod ehci_pci drm_kms_helper xhci_hcd ehci_hcd r8169 mii usbcore drm nvme nvme_core fjes button [last unloaded: net2280] CPU: 5 PID: 829 Comm: bash Not tainted 4.9.0-rc7 #1 Hardware name: To Be Filled By O.E.M.
