[ Upstream commit 3cad8f91 ] Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set. To cleanup pktgen on exit, trap has been added for EXIT signal. Signed-off-by:

[ Upstream commit 9b211f9c ] The CEC_MSG_GIVE_DECK_STATUS and CEC_MSG_GIVE_TUNER_DEVICE_STATUS commands both have a status_req argument: ON, OFF, ONCE. If ON or ONCE, then the follower will reply with a STATUS message. Either once or whenever the status changes (status_req == ON). If status_req == OFF, then it will stop sending continuous status updates, but the follower will *not* send a STATUS message in that case. This means that if status_req == OFF, then msg->reply should be 0 as well since no reply is expected in that case. Signed-off-by:

[ Upstream commit 39abcc84 ] When R-Car Gen3 USB 2.0 is in Gadget mode, if host is detached an interrupt will be generated and Suspended state bit is set in interrupt status register. Interrupt handler will call driver->suspend(composite_suspend) if suspended state bit is set. composite_suspend will call ffs_func_suspend which will post FUNCTIONFS_SUSPEND and will be consumed by user space application via /dev/ep0. To be able to detect host detach, extend the DVSQ_MASK to cover the Suspended bit of the DVSQ[2:0] bitfield from the Interrupt Status Register 0 (INTSTS0) register and perform appropriate action in the DVST interrupt handler (usbhsg_irq_dev_state). Without this commit, disconnection of the phone from R-Car-H3 ES2.0 Salvator-X CN9 port is not recognized and reverse role switch does not happen. If phone is connected again it does not enumerate. With this commit, disconnection will be recognized and reverse role switch will happen by a user space application. If phone is connected again it will enumerate properly and will become visible in the output of 'lsusb'. Signed-off-by:

[ Upstream commit 3143b459 ] The driver stores frame format settings supposed to be in line with hardware state in a device private structure. Since the driver initial submission, those settings are updated before they are actually applied on hardware. If an error occurs on device update, the stored settings my not reflect hardware state anymore and consecutive calls to .get_fmt() may return incorrect information. That in turn may affect ability of a bridge device to use correct DMA transfer settings if such incorrect informmation on active frame format returned by .get_fmt() is used. Assuming a failed device update means its state hasn't changed, update frame format related settings stored in the device private structure only after they are successfully applied so the stored values always reflect hardware state as closely as possible.

[ Upstream commit 7718cf03 ] In case we don't set the sg_prot_tablesize, the scsi layer assign the default size (65535 entries). We should limit this size since we should take into consideration the underlaying device capability. This cap is considered when calculating the sg_tablesize.

[ Upstream commit 9f918a72 ] This change is necessary for spidev devices (e.g. /dev/spidev3.0) working in the slave mode (like NXP's dspi driver for Vybrid SoC). When SPI HW works in this mode - the master is responsible for providing CS and CLK signals. However, when some fault happens - like for example distortion on SPI lines - the SPI Linux driver needs a chance to recover from this abnormal situation and prepare itself for next (correct) transmission. This change doesn't pose any threat on drivers working in master mode as spi_slave_abort() function checks if SPI slave mode is supported. Signed-off-by:

commit add9d56d upstream. The current PCM code doesn't initialize explicitly the buffers allocated for PCM streams, hence it might leak some uninitialized kernel data or previous stream contents by mmapping or reading the buffer before actually starting the stream. Since this is a common problem, this patch simply adds the clearance of the buffer data at hw_params callback. Although this does only zero-clear no matter which format is used, which doesn't mean the silence for some formats, but it should be OK because the intention is just to clear the previous data on the buffer.

commit 9bc574de upstream. My fsstress modifications coupled with generic/475 uncovered a failure to mount and replay the log if we hit a orphaned root. We do not want to replay the log for an orphan root, but it's completely legitimate to have an orphaned root with a log attached. Fix this by simply skipping replaying the log. We still need to pin it's root node so that we do not overwrite it while replaying other logs, as we re-read the log root at every stage of the replay. CC: stable@vger.kernel.org # 4.4+ Reviewed-by:

commit 07b39753 upstream. Currently, if we drop a packet, we exit from NAPI loop before the budget is consumed. In some situations this will make the RX processing stall e.g. when flood pinging the system with oversized packets, as the errorneous packets are not dropped efficiently. If we drop a packet, we should just continue to the next one as long as the budget allows. Signed-off-by:

commit 057d476f upstream. A race in xhci USB3 remote wake handling may force device back to suspend after it initiated resume siganaling, causing a missed resume event or warm reset of device. When a USB3 link completes resume signaling and goes to enabled (UO) state a interrupt is issued and the interrupt handler will clear the bus_state->port_remote_wakeup resume flag, allowing bus suspend. If the USB3 roothub thread just finished reading port status before the interrupt, finding ports still in suspended (U3) state, but hasn't yet started suspending the hub, then the xhci interrupt handler will clear the flag that prevented roothub suspend and allow bus to suspend, forcing all port links back to suspended (U3) state. Example case: usb_runtime_suspend() # because all ports still show suspended U3 usb_suspend_both() hub_suspend(); # successful as hub->wakeup_bits not set yet ==> INTERRUPT xhci_irq() handle_port_status() clear bus_state->port_remote_wakeup usb_wakeup_notification() sets hub->wakeup_bits; kick_hub_wq() <== END INTERRUPT hcd_bus_suspend() xhci_bus_suspend() # success as port_remote_wakeup bits cleared Fix this by increasing roothub usage count during port resume to prevent roothub autosuspend, and by making sure bus_state->port_remote_wakeup flag is only cleared after resume completion is visible, i.e. after xhci roothub returned U0 or other non-U3 link state link on a get port status request.

commit 474e5595 upstream. We got the following warnings from thin_check during thin-pool setup: $ thin_check /dev/vdb examining superblock examining devices tree missing devices: [1, 84] too few entries in btree_node: 41, expected at least 42 (block 138, max_entries = 126) examining mapping tree The phenomenon is the number of entries in one node of details_info tree is less than (max_entries / 3). And it can be easily reproduced by the following procedures: $ new a thin pool $ presume the max entries of details_info tree is 126 $ new 127 thin devices (e.g. 1~127) to make the root node being full and then split $ remove the first 43 (e.g. 1~43) thin devices to make the children reblance repeatedly $ stop the thin pool $ thin_check The root cause is that the B-tree removal procedure in __rebalance2() doesn't guarantee the invariance: the minimal number of entries in non-root node should be >= (max_entries / 3). Simply fix the problem by increasing the rebalance threshold to make sure the number of entries in each child will be greater than or equal to (max_entries / 3 + 1), so no matter which child is used for removal, the number will still be valid.

Specifically free_irq() may release resources required by the irqbypass del_producer() callback. Notably an example provided by Marc Zyngier on arm64 with GICv4 that he indicates has the potential to wedge the hardware: free_irq(irq) __free_irq(irq) irq_domain_deactivate_irq(irq) its_irq_domain_deactivate() [unmap the VLPI from the ITS] kvm_arch_irq_bypass_del_producer(cons, prod) kvm_vgic_v4_unset_forwarding(kvm, irq, ...) its_unmap_vlpi(irq) [Unmap the VLPI from the ITS (again), remap the original LPI] Signed-off-by:

commit 44805b0e upstream. Currently the client translates O_SYNC and O_DIRECT flags into corresponding SMB create options when openning a file. The problem is that on reconnect when the file is being re-opened the client doesn't set those flags and it causes a server to reject re-open requests because create options don't match. The latter means that any subsequent system call against that open file fail until a share is re-mounted. Fix this by properly setting SMB create options when re-openning files after reconnects.

commit 36de10c4 upstream. Virtual and translated addresses retrieved by the xtensa TLB sanity checker must be consistent, i.e. correspond to the same state of the checked TLB entry. KASAN shadow memory is mapped dynamically using auto-refill TLB entries and thus may change TLB state between the virtual and translated address retrieval, resulting in false TLB insanity report. Move read_xtlb_translation close to read_xtlb_virtual to make sure that read values are consistent.
