commit 44157641 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. v2: rebase (Mika) v3: rebase (Mika) Signed-off-by:

[ Upstream commit ad8a7220 ] The "42f5cda5" commit rightly set SOCK_DONE on peer shutdown, but there is an issue if we receive the SHUTDOWN(RDWR) while the virtio_transport_close_timeout() is scheduled. In this case, when the timeout fires, the SOCK_DONE is already set and the virtio_transport_close_timeout() will not call virtio_transport_reset() and virtio_transport_do_close(). This causes that both sockets remain open and will never be released, preventing the unloading of [virtio|vhost]_transport modules. This patch fixes this issue, calling virtio_transport_reset() and virtio_transport_do_close() when we receive the SHUTDOWN(RDWR) and there is nothing left to read.

[ Upstream commit 1615fe41 ] 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. Signed-off-by:

[ Upstream commit 97664bc2 ] Same as commit 1b4a7510 ("netfilter: ipset: Copy the right MAC address in bitmap:ip,mac and hash:ip,mac sets"), another copy and paste went wrong in commit 8cc4ccf5 ("netfilter: ipset: Allow matching on destination MAC address for mac and ipmac sets"). When I fixed this for IPv4 in 1b4a7510, I didn't realise that hash:ip,mac sets also support IPv6 as family, and this is covered by a separate function, hash_ipmac6_kadt(). In hash:ip,mac sets, the first dimension is the IP address, and the second dimension is the MAC address: check the IPSET_DIM_TWO_SRC flag in flags while deciding which MAC address to copy, destination or source. This way, mixing source and destination matches for the two dimensions of ip,mac hash type works as expected, also for IPv6. With this setup: ip netns add A ip link add veth1 type veth peer name veth2 netns A ip addr add 2001:db8::1/64 dev veth1 ip -net A addr add 2001:db8::2/64 dev veth2 ip link set veth1 up ip -net A link set veth2 up dst=$(ip netns exec A cat /sys/class/net/veth2/address) ip netns exec A ipset create test_hash hash:ip,mac family inet6 ip netns exec A ipset add test_hash 2001:db8::1,${dst} ip netns exec A ip6tables -A INPUT -p icmpv6 --icmpv6-type 135 -j ACCEPT ip netns exec A ip6tables -A INPUT -m set ! --match-set test_hash src,dst -j DROP ipset now correctly matches a test packet: # ping -c1 2001:db8::2 >/dev/null # echo $? 0 Reported-by:

commit 65de03e2 upstream. cgroup writeback tries to refresh the associated wb immediately if the current wb is dead. This is to avoid keeping issuing IOs on the stale wb after memcg - blkcg association has changed (ie. when blkcg got disabled / enabled higher up in the hierarchy). Unfortunately, the logic gets triggered spuriously on inodes which are associated with dead cgroups. When the logic is triggered on dead cgroups, the attempt fails only after doing quite a bit of work allocating and initializing a new wb. While c3aab9a0 ("mm/filemap.c: don't initiate writeback if mapping has no dirty pages") alleviated the issue significantly as it now only triggers when the inode has dirty pages. However, the condition can still be triggered before the inode is switched to a different cgroup and the logic simply doesn't make sense. Skip the immediate switching if the associated memcg is dying. This is a simplified version of the following two patches: * https://lore.kernel.org/linux-mm/20190513183053.GA73423@dennisz-mbp/ * http://lkml.kernel.org/r/156355839560.2063.5265687291430814589.stgit@buzz Cc: Konstantin Khlebnikov <khlebnikov@yandex-team.ru> Fixes: e8a7abf5 ("writeback: disassociate inodes from dying bdi_writebacks") Acked-by:

commit c3aab9a0 upstream. Functions like filemap_write_and_wait_range() should do nothing if inode has no dirty pages or pages currently under writeback. But they anyway construct struct writeback_control and this does some atomic operations if CONFIG_CGROUP_WRITEBACK=y - on fast path it locks inode->i_lock and updates state of writeback ownership, on slow path might be more work. Current this path is safely avoided only when inode mapping has no pages. For example generic_file_read_iter() calls filemap_write_and_wait_range() at each O_DIRECT read - pretty hot path. This patch skips starting new writeback if mapping has no dirty tags set. If writeback is already in progress filemap_write_and_wait_range() will wait for it.

[ Upstream commit b0814361 ] blkcg_print_stat() iterates blkgs under RCU and doesn't test whether the blkg is online. This can call into pd_stat_fn() on a pd which is still being initialized leading to an oops. The heaviest operation - recursively summing up rwstat counters - is already done while holding the queue_lock. Expand queue_lock to cover the other operations and skip the blkg if it isn't online yet. The online state is protected by both blkcg and queue locks, so this guarantees that only online blkgs are processed. Signed-off-by:

[ Upstream commit 63bdef6c ] 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.

[ Upstream commit 29c2c6aa ] 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.

[ Upstream commit 8d5cfd7f ] 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. Signed-off-by:

[ Upstream commit b9cd75e6 ] 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).

[ Upstream commit 1c44ce56 ] Background information: the driver operates the hardware in a mode where a single VLAN can be transmitted as untagged on a particular egress port. That is the "native VLAN on trunk port" use case. Its value is held in port->vid. Consider the following command sequence (no network manager, all interfaces are down, debugging prints added by me): $ ip link add dev br0 type bridge vlan_filtering 1 $ ip link set dev swp0 master br0 Kernel code path during last command: br_add_slave -> ocelot_netdevice_port_event (NETDEV_CHANGEUPPER): [ 21.401901] ocelot_vlan_port_apply: port 0 vlan aware 0 pvid 0 vid 0 br_add_slave -> nbp_vlan_init -> switchdev_port_attr_set -> ocelot_port_attr_set (SWITCHDEV_ATTR_ID_BRIDGE_VLAN_FILTERING): [ 21.413335] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 0 vid 0 br_add_slave -> nbp_vlan_init -> nbp_vlan_add -> br_switchdev_port_vlan_add -> switchdev_port_obj_add -> ocelot_port_obj_add -> ocelot_vlan_vid_add [ 21.667421] ocelot_vlan_port_apply: port 0 vlan aware 1 pvid 1 vid 1 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. $ ip link set dev swp0 up [ 31.722956] 8021q: adding VLAN 0 to HW filter on device swp0 do_setlink -> dev_change_flags -> vlan_vid_add -> ocelot_vlan_rx_add_vid -> ocelot_vlan_vid_add: [ 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.

[ Upstream commit af8fd042 ] 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. Reviewed-by:

[ Upstream commit d482c7bb ] 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. Signed-off-by:

[ Upstream commit e431e79b ] This saves us writing the IBS control MSR twice when disabling the event. I searched revision guides for all families since 10h, and did not find occurrence of erratum #420, nor anything remotely similar: so we isolate the secondary MSR write to family 10h only. Also unconditionally update the count mask for IBS Op implementations that have read & writeable current count (CurCnt) fields in addition to the MaxCnt field. These bits were reserved on prior implementations, and therefore shouldn't have negative impact. Signed-off-by:

[ Upstream commit 1a1c851b ] 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.
