      drm/i915: Remove Master tables from cmdparser · fba4207c
      Jon Bloomfield 提交于
      commit 66d8aba1cd6db34af10de465c0d52af679288cb6 upstream.
      
      The previous patch has killed support for secure batches
      on gen6+, and hence the cmdparsers master tables are
      now dead code. Remove them.

      drm/i915: Disable Secure Batches for gen6+ · f1ff7708
      Jon Bloomfield 提交于
      commit 44157641d448cbc0c4b73c5231d2b911f0cb0427 upstream.
      
      Retroactively stop reporting support for secure batches
      through the api for gen6+ so that older binaries trigger
      the fallback path instead.
      
      Older binaries use secure batches pre gen6 to access resources
      that are not available to normal usermode processes. However,
      all known userspace explicitly checks for HAS_SECURE_BATCHES
      before relying on the secure batch feature.
      
      Since there are no known binaries relying on this for newer gens
      we can kill secure batches from gen6, via I915_PARAM_HAS_SECURE_BATCHES.

      iio: imu: mpu6050: Fix FIFO layout for ICM20602 · 2e7e3f16
      Steve Moskovchenko 提交于
      [ Upstream commit 1615fe41a1959a2ee2814ba62736b2bb54e9802a ]
      
      The MPU6050 driver has recently gained support for the
      ICM20602 IMU, which is very similar to MPU6xxx. However,
      the ICM20602's FIFO data specifically includes temperature
      readings, which were not present on MPU6xxx parts. As a
      result, the driver will under-read the ICM20602's FIFO
      register, causing the same (partial) sample to be returned
      for all reads, until the FIFO overflows.
      
      Fix this by adding a table of scan elements specifically
      for the ICM20602, which takes the extra temperature data
      into consideration.
      
      While we're at it, fix the temperature offset and scaling
      on ICM20602, since it uses different scale/offset constants
      than the rest of the MPU6xxx devices.

      pinctrl: cherryview: Fix irq_valid_mask calculation · 30b96939
      Hans de Goede 提交于
      [ Upstream commit 63bdef6cd6941917c823b9cc9aa0219d19fcb716 ]
      
      Commit 03c4749d ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
      GPIO translation") has made the cherryview gpio numbers sparse, to get
      a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.
      
      This has greatly simplified things, but the code setting the
      irq_valid_mask was not updated for this, so the valid mask is still in
      the old "compressed" numbering with the gaps in the pin numbers skipped,
      which is wrong as irq_valid_mask needs to be expressed in gpio numbers.
      
      This results in the following error on devices using pin 24 (0x0018) on
      the north GPIO controller as an ACPI event source:
      
      [    0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ
      
      This has been reported (by email) to be happening on a Caterpillar CAT T20
      tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.
      
      This commit uses the pin number instead of the compressed index into
      community->pins to clear the correct bits in irq_valid_mask for GPIOs
      using GPEs for interrupts, fixing these errors and in case of the
      Medion Akoya e2215t also fixing the LID switch not working.

      pinctrl: intel: Avoid potential glitches if pin is in GPIO mode · 2c655a11
      Andy Shevchenko 提交于
      [ Upstream commit 29c2c6aa32405dfee4a29911a51ba133edcedb0f ]
      
      When consumer requests a pin, in order to be on the safest side,
      we switch it first to GPIO mode followed by immediate transition
      to the input state. Due to posted writes it's luckily to be a single
      I/O transaction.
      
      However, if firmware or boot loader already configures the pin
      to the GPIO mode, user expects no glitches for the requested pin.
      We may check if the pin is pre-configured and leave it as is
      till the actual consumer toggles its state to avoid glitches.

      igb: Fix constant media auto sense switching when no cable is connected · 4a055717

      [ Upstream commit 8d5cfd7f76a2414e23c74bb8858af7540365d985 ]
      
      At least on the i350 there is an annoying behavior that is maybe also
      present on 82580 devices, but was probably not noticed yet as MAS is not
      widely used.
      
      If no cable is connected on both fiber/copper ports the media auto sense
      code will constantly swap between them as part of the watchdog task and
      produce many unnecessary kernel log messages.
      
      The swap code responsible for this behavior (switching to fiber) should
      not be executed if the current media type is copper and there is no signal
      detected on the fiber port. In this case we can safely wait until the
      AUTOSENSE_EN bit is cleared.

      net: mscc: ocelot: refuse to overwrite the port's native vlan · 214e4f0e
      Vladimir Oltean 提交于
      [ Upstream commit b9cd75e6689560140dadaed98eb4b41aad75d55d ]
      
      The switch driver keeps a "vid" variable per port, which signifies _the_
      VLAN ID that is stripped on that port's egress (aka the native VLAN on a
      trunk port).
      
      That is the way the hardware is designed (mostly). The port->vid is
      programmed into REW:PORT:PORT_VLAN_CFG:PORT_VID and the rewriter is told
      to send all traffic as tagged except the one having port->vid.
      
      There exists a possibility of finer-grained egress untagging decisions:
      using the VCAP IS1 engine, one rule can be added to match every
      VLAN-tagged frame whose VLAN should be untagged, and set POP_CNT=1 as
      action. However, the IS1 can hold at most 512 entries, and the VLANs are
      in the order of 6 * 4096.
      
      So the code is fine for now. But this sequence of commands:
      
      $ bridge vlan add dev swp0 vid 1 pvid untagged
      $ bridge vlan add dev swp0 vid 2 untagged
      
      makes untagged and pvid-tagged traffic be sent out of swp0 as tagged
      with VID 1, despite user's request.
      
      Prevent that from happening. The user should temporarily remove the
      existing untagged VLAN (1 in this case), add it back as tagged, and then
      add the new untagged VLAN (2 in this case).

      So far so good. The bridge has replaced the driver's default pvid used
      in standalone mode (0) with its own default_pvid (1). The port's vid
      (native VLAN) has also changed from 0 to 1.

      [   31.728700] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 1 vid 0
      
      The 8021q module uses the .ndo_vlan_rx_add_vid API on .ndo_open to make
      ports be able to transmit and receive 802.1p-tagged traffic by default.
      This API is supposed to offload a VLAN sub-interface, which for a switch
      port means to add a VLAN that is not a pvid, and tagged on egress.
      
      But the driver implementation of .ndo_vlan_rx_add_vid is wrong: it adds
      back vid 0 as "egress untagged". Now back to the initial paragraph:
      there is a single untagged VID that the driver keeps track of, and that
      has just changed from 1 (the pvid) to 0. So this breaks the bridge
      core's expectation, because it has changed vid 1 from untagged to
      tagged, when what the user sees is.
      
      $ bridge vlan
      port    vlan ids
      swp0     1 PVID Egress Untagged
      
      br0      1 PVID Egress Untagged
      
      But curiously, instead of manifesting itself as "untagged and
      pvid-tagged traffic gets sent as tagged on egress", the bug:
      
      - is hidden when vlan_filtering=0
      - manifests as dropped traffic when vlan_filtering=1, due to this setting:
      
      	if (port->vlan_aware && !port->vid)
      		/* If port is vlan-aware and tagged, drop untagged and priority
      		 * tagged frames.
      		 */
      		val |= ANA_PORT_DROP_CFG_DROP_UNTAGGED_ENA |
      		       ANA_PORT_DROP_CFG_DROP_PRIO_S_TAGGED_ENA |
      		       ANA_PORT_DROP_CFG_DROP_PRIO_C_TAGGED_ENA;
      
      which would have made sense if it weren't for this bug. The setting's
      intention was "this is a trunk port with no native VLAN, so don't accept
      untagged traffic". So the driver was never expecting to set VLAN 0 as
      the value of the native VLAN, 0 was just encoding for "invalid".
      
      So the fix is to not send 802.1p traffic as untagged, because that would
      change the port's native vlan to 0, unbeknownst to the bridge, and
      trigger unexpected code paths in the driver.

      nvme-multipath: fix possible io hang after ctrl reconnect · 6376736d
      Anton Eidelman 提交于
      [ Upstream commit af8fd0424713a2adb812d10d55e86718152cf656 ]
      
      The following scenario results in an IO hang:
      1) ctrl completes a request with NVME_SC_ANA_TRANSITION.
         NVME_NS_ANA_PENDING bit in ns->flags is set and ana_work is triggered.
      2) ana_work: nvme_read_ana_log() tries to get the ANA log page from the ctrl.
         This fails because ctrl disconnects.
         Therefore nvme_update_ns_ana_state() is not called
         and NVME_NS_ANA_PENDING bit in ns->flags is not cleared.
      3) ctrl reconnects: nvme_mpath_init(ctrl,...) calls
         nvme_read_ana_log(ctrl, groups_only=true).
         However, nvme_update_ana_state() does not update namespaces
         because nr_nsids = 0 (due to groups_only mode).
      4) scan_work calls nvme_validate_ns() finds the ns and re-validates OK.
      
      Result:
      The ctrl is now live but NVME_NS_ANA_PENDING bit in ns->flags is still set.
      Consequently ctrl will never be considered a viable path by __nvme_find_path().
      IO will hang if ctrl is the only or the last path to the namespace.
      
      More generally, while ctrl is reconnecting, its ANA state may change.
      And because nvme_mpath_init() requests ANA log in groups_only mode,
      these changes are not propagated to the existing ctrl namespaces.
      This may result in a mal-function or an IO hang.
      
      Solution:
      nvme_mpath_init() will nvme_read_ana_log() with groups_only set to false.
      This will not harm the new ctrl case (no namespaces present),
      and will make sure the ANA state of namespaces gets updated after reconnect.
      
      Note: Another option would be for nvme_mpath_init() to invoke
      nvme_parse_ana_log(..., nvme_set_ns_ana_state) for each existing namespace.

      Endpoints with a maxpacket length of 0 are probably useless.  They
      can't transfer any data, and it's not at all unlikely that an HCD will
      crash or hang when trying to handle an URB for such an endpoint.
      
      Currently the USB core does not check for endpoints having a maxpacket
      value of 0.  This patch adds a check, printing a warning and skipping
      over any endpoints it catches.
      
      Now, the USB spec does not rule out endpoints having maxpacket = 0.
      But since they wouldn't have any practical use, there doesn't seem to
      be any good reason for us to accept them.

      We meet several NULL pointer issues if configfs_composite_unbind
      and composite_setup (or composite_disconnect) are running together.
      These issues occur when do the function switch stress test, the
      configfs_compsoite_unbind is called from user mode by
      echo "" to /sys/../UDC entry, and meanwhile, the setup interrupt
      or disconnect interrupt occurs by hardware. The composite_setup
      will get the cdev from get_gadget_data, but configfs_composite_unbind
      will set gadget data as NULL, so the NULL pointer issue occurs.
      This concurrent is hard to reproduce by native kernel, but can be
      reproduced by android kernel.
      
      In this commit, we introduce one spinlock belongs to structure
      gadget_info since we can't use the same spinlock in usb_composite_dev
      due to exclusive running together between composite_setup and
      configfs_composite_unbind. And one bit flag 'unbind' to indicate the
      code is at unbind routine, this bit is needed due to we release the
      lock at during configfs_composite_unbind sometimes, and composite_setup
      may be run at that time.

      In dwc3_pci_probe a call to platform_device_alloc allocates a device
      which is correctly put in case of error except one case: when the call to
      platform_device_add_properties fails it directly returns instead of
      going to error handling. This commit replaces return with the goto.

      Chandana Kishori Chiluveru 提交于

      composite_dev_cleanup call from the failure of configfs_composite_bind
      frees up the cdev->os_desc_req and cdev->req. If the previous calls of
      bind and unbind is successful these will carry stale values.
      
      Consider the below sequence of function calls:
      configfs_composite_bind()
              composite_dev_prepare()
                      - Allocate cdev->req, cdev->req->buf
              composite_os_desc_req_prepare()
                      - Allocate cdev->os_desc_req, cdev->os_desc_req->buf
      configfs_composite_unbind()
              composite_dev_cleanup()
                      - free the cdev->os_desc_req->buf and cdev->req->buf
      Next composition switch
      configfs_composite_bind()
              - If it fails goto err_comp_cleanup will call the
      	  composite_dev_cleanup() function
              composite_dev_cleanup()
      	        - calls kfree up with the stale values of cdev->req->buf and
      		  cdev->os_desc_req from the previous configfs_composite_bind
      		  call. The free call on these stale values leads to double free.
      
      Hence, Fix this issue by setting request and buffer pointer to NULL after
      kfree.

      macsec: fix refcnt leak in module exit routine · 3a2675a2
      Taehee Yoo 提交于
      [ Upstream commit 2bce1ebed17da54c65042ec2b962e3234bad5b47 ]
      
      When a macsec interface is created, it increases a refcnt to a lower
      device(real device). when macsec interface is deleted, the refcnt is
      decreased in macsec_free_netdev(), which is ->priv_destructor() of
      macsec interface.
      
      The problem scenario is this.
      When nested macsec interfaces are exiting, the exit routine of the
      macsec module makes refcnt leaks.
      
      Test commands:
          ip link add dummy0 type dummy
          ip link add macsec0 link dummy0 type macsec
          ip link add macsec1 link macsec0 type macsec
          modprobe -rv macsec
      
      [  208.629433] unregister_netdevice: waiting for macsec0 to become free. Usage count = 1
      
      Steps of exit routine of macsec module are below.
      1. Calls ->dellink() in __rtnl_link_unregister().
      2. Checks refcnt and wait refcnt to be 0 if refcnt is not 0 in
      netdev_run_todo().
      3. Calls ->priv_destruvtor() in netdev_run_todo().
      
      Step2 checks refcnt, but step3 decreases refcnt.
      So, step2 waits forever.
      
      This patch makes the macsec module do not hold a refcnt of the lower
      device because it already holds a refcnt of the lower device with
      netdev_upper_dev_link().

      bonding: fix unexpected IFF_BONDING bit unset · 0d0ca85a
      Taehee Yoo 提交于
      [ Upstream commit 65de65d9033750d2cf1b336c9d6e9da3a8b5cc6e ]
      
      The IFF_BONDING means bonding master or bonding slave device.
      ->ndo_add_slave() sets IFF_BONDING flag and ->ndo_del_slave() unsets
      IFF_BONDING flag.
      
      bond0<--bond1
      
      Both bond0 and bond1 are bonding device and these should keep having
      IFF_BONDING flag until they are removed.
      But bond1 would lose IFF_BONDING at ->ndo_del_slave() because that routine
      do not check whether the slave device is the bonding type or not.
      This patch adds the interface type check routine before removing
      IFF_BONDING flag.
      
      Test commands:
          ip link add bond0 type bond
          ip link add bond1 type bond
          ip link set bond1 master bond0
          ip link set bond1 nomaster
          ip link del bond1 type bond
          ip link add bond1 type bond

      RDMA/uverbs: Prevent potential underflow · 02725331
      Dan Carpenter 提交于
      [ Upstream commit a9018adfde809d44e71189b984fa61cc89682b5e ]
      
      The issue is in drivers/infiniband/core/uverbs_std_types_cq.c in the
      UVERBS_HANDLER(UVERBS_METHOD_CQ_CREATE) function.  We check that:
      
              if (attr.comp_vector >= attrs->ufile->device->num_comp_vectors) {
      
      But we don't check if "attr.comp_vector" is negative.  It could
      potentially lead to an array underflow.  My concern would be where
      cq->vector is used in the create_cq() function from the cxgb4 driver.
      
      And really "attr.comp_vector" is appears as a u32 to user space so that's
      the right type to use.

      scsi: qla2xxx: fixup incorrect usage of host_byte · d582769a
      Hannes Reinecke 提交于
      [ Upstream commit 66cf50e65b183c863825f5c28a818e3f47a72e40 ]
      
      DRIVER_ERROR is a a driver byte setting, not a host byte.  The qla2xxx
      driver should rather return DID_ERROR here to be in line with the other
      drivers.
