BugLink: https://bugs.launchpad.net/bugs/1889928 commit 65caafd0 upstream. Reverting commit d03727b2 "NFSv4 fix CLOSE not waiting for direct IO compeletion". This patch made it so that fput() by calling inode_dio_done() in nfs_file_release() would wait uninterruptably for any outstanding directIO to the file (but that wait on IO should be killable). The problem the patch was also trying to address was REMOVE returning ERR_ACCESS because the file is still opened, is supposed to be resolved by server returning ERR_FILE_OPEN and not ERR_ACCESS.

BugLink: https://bugs.launchpad.net/bugs/1889928 [ Upstream commit 9dc829a1 ] When this driver transmits data, first this driver will remove a pseudo header of 1 byte, then the lapb module will prepend the LAPB header of 2 or 3 bytes, then this driver will prepend a length field of 2 bytes, then the underlying Ethernet device will prepend its own header. So, the header length required should be: -1 + 3 + 2 + "the header length needed by the underlying device". This patch fixes kernel panic when this driver is used with AF_PACKET SOCK_DGRAM sockets.

BugLink: https://bugs.launchpad.net/bugs/1889928 [ Upstream commit 0b467b63 ] Without this patch, eapol frames cannot be received in mesh mode, when 802.1X should be used. Initially only a MGTK is defined, which is found and set as rx->key, when there are no other keys set. ieee80211_drop_unencrypted would then drop these eapol frames, as they are data frames without encryption and there exists some rx->key. Fix this by differentiating between mesh eapol frames and other data frames with existing rx->key. Allow mesh mesh eapol frames only if they are for our vif address. With this patch in-place, ieee80211_rx_h_mesh_fwding continues after the ieee80211_drop_unencrypted check and notices, that these eapol frames have to be delivered locally, as they should.

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 01cfcde9 upstream. task_h_load() can return 0 in some situations like running stress-ng mmapfork, which forks thousands of threads, in a sched group on a 224 cores system. The load balance doesn't handle this correctly because env->imbalance never decreases and it will stop pulling tasks only after reaching loop_max, which can be equal to the number of running tasks of the cfs. Make sure that imbalance will be decreased by at least 1. misfit task is the other feature that doesn't handle correctly such situation although it's probably more difficult to face the problem because of the smaller number of CPUs and running tasks on heterogenous system. We can't simply ensure that task_h_load() returns at least one because it would imply to handle underflow in other places. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 14b0e83d upstream. This patch fixes a bug which does not let FAN mode to be changed from sysfs(pwm1_enable). i.e pwm1_enable can not be set to 3, it will always remain at 0. This is caused because the device driver handles the result of "read_u8_from_i2c(client, REG_FAN_CONF1, &conf_reg)" incorrectly. The driver thinks an error has occurred if the (result != 0). This has been fixed by changing the condition to (result < 0). Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1888690 commit bf12fdf0 upstream. While e3a3c3a2 ("UIO: fix uio_pdrv_genirq with device tree but no interrupt") added support for using uio_pdrv_genirq for devices without interrupt for device tree platforms, the removal of uio_pdrv in 26dac3c4 ("uio: Remove uio_pdrv and use uio_pdrv_genirq instead") broke the support for non device tree platforms. This change fixes this, so that uio_pdrv_genirq can be used without interrupt on all platforms. This still leaves the support that uio_pdrv had for custom interrupt handler lacking, as uio_pdrv_genirq does not handle it (yet).

BugLink: https://bugs.launchpad.net/bugs/1888690 commit e852c2c2 upstream. It's not needed to set driver to NULL in mei_cl_device_remove() which is bus_type remove() handler as this is done anyway in __device_release_driver(). Actually this is causing an endless loop in driver_detach() on ubuntu patched kernel, while removing (rmmod) the mei_hdcp module. The reason list_empty(&drv->p->klist_devices.k_list) is always not-empty. as the check is always true in __device_release_driver() if (dev->driver != drv) return; The non upstream patch is causing this behavior, titled: 'vfio -- release device lock before userspace requests' Nevertheless the fix is correct also for the upstream.

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 31070f6c upstream. The ioctl encoding for this parameter is a long but the documentation says it should be an int and the kernel drivers expect it to be an int. If the fuse driver treats this as a long it might end up scribbling over the stack of a userspace process that only allocated enough space for an int. This was previously discussed in [1] and a patch for fuse was proposed in [2]. From what I can tell the patch in [2] was nacked in favor of adding new, "fixed" ioctls and using those from userspace. However there is still no "fixed" version of these ioctls and the fact is that it's sometimes infeasible to change all userspace to use the new one. Handling the ioctls specially in the fuse driver seems like the most pragmatic way for fuse servers to support them without causing crashes in userspace applications that call them.

Apparently, it's a regular CH340, but I've confirmed with others that also bought this board that the PID found on this device (0x7522) differs from other devices with the "same" converter (0x7523). Simply adding its PID to the driver and rebuilding it made it work as expected. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 5c45d04c upstream. This is a UPB (Universal Powerline Bus) PIM (Powerline Interface Module) which allows for controlling multiple UPB compatible devices from Linux using the standard serial interface. Based on vendor application source code there are two different models of USB based PIM devices in addition to a number of RS232 based PIM's. The vendor UPB application source contains the following USB ID's: #define USB_PCS_VENDOR_ID 0x04b4 #define USB_PCS_PIM_PRODUCT_ID 0x5500 #define USB_SAI_VENDOR_ID 0x17dd #define USB_SAI_PIM_PRODUCT_ID 0x5500 The first set of ID's correspond to the PIM variant sold by Powerline Control Systems while the second corresponds to the Simply Automated Incorporated PIM. As the product ID for both of these match the default cypress HID->COM RS232 product ID it assumed that they both use an internal variant of this HID->COM RS232 converter hardware. However as the vendor ID for the Simply Automated variant is different we need to also add it to the cypress_M8 driver so that it is properly detected. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 9b7e5208 upstream. USB MIDI driver has an error recovery mechanism to resubmit the URB in the delayed timer handler, and this may race with the standard start / stop operations. Although both start and stop operations themselves don't race with each other due to the umidi->mutex protection, but this isn't applied to the timer handler. For fixing this potential race, the following changes are applied: - Since the timer handler can't use the mutex, we apply the umidi->disc_lock protection at each input stream URB submission; this also needs to change the GFP flag to GFP_ATOMIC - Add a check of the URB refcount and skip if already submitted - Move the timer cancel call at disconnection to the beginning of the procedure; this assures the in-flight timer handler is gone properly before killing all pending URBs Reported-by: syzbot+0f4ecfe6a2c322c81728@syzkaller.appspotmail.com Reported-by: syzbot+5f1d24c49c1d2c427497@syzkaller.appspotmail.com Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200710160656.16819-1-tiwai@suse.deSigned-off-by:

BugLink: https://bugs.launchpad.net/bugs/1888690 commit 6e8a914a upstream. LINE6 drivers create stream URBs with a fixed pipe without checking its validity, and this may lead to a kernel WARNING at the submission when a malformed USB descriptor is passed. For avoiding the kernel warning, perform the similar sanity checks for each pipe type at creating a URB.

BugLink: https://bugs.launchpad.net/bugs/1888690 commit e901b987 upstream. This patch adds a new helper function to perform a sanity check of the given URB to see whether it contains a valid endpoint. It's a light- weight version of what usb_submit_urb() does, but without the kernel warning followed by the stack trace, just returns an error code. Especially for a driver that doesn't parse the descriptor but fills the URB with the fixed endpoint (e.g. some quirks for non-compliant devices), this kind of check is preferable at the probe phase before actually submitting the urb.

As the code comments in perf_stat_process_counter() say, we calculate counter's data every interval, and the display code shows ps->res_stats avg value. We need to zero the stats for interval mode. But the current code only zeros the res_stats[0], it doesn't zero the res_stats[1] and res_stats[2], which are for ena and run of counter. This patch zeros the whole res_stats[] for interval mode.
