BugLink: https://bugs.launchpad.net/bugs/1792377 [ Upstream commit 3b8d5735 ] The touch sensors on the 2nd-gen Intuos tablets don't use a 4096x4096 sensor like other similar tablets (3rd-gen Bamboo, Intuos5, etc.). The incorrect maximum XY values don't normally affect userspace since touch input from these devices is typically relative rather than absolute. It does, however, cause problems when absolute distances need to be measured, e.g. for gesture recognition. Since the resolution of the touch sensor on these devices is 10 units / mm (versus 100 for the pen sensor), the proper maximum values can be calculated by simply dividing by 10.

BugLink: https://bugs.launchpad.net/bugs/1792377 [ Upstream commit 484c016d ] Driver performs the internal reload when it receives tx-timeout event from the OS. Internal reload might fail in some scenarios e.g., fatal HW issues. In such cases OS still see the link, which would result in undesirable functionalities such as re-generation of tx-timeouts. The patch addresses this issue by indicating the link-down to OS when tx-timeout is detected, and keeping the link in down state till the internal reload is successful. Please consider applying it to 'net' branch. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1792377 [ Upstream commit bda31539 ] During assemble, the spare marked for replacement is not checked. conf->fullsync cannot be updated to be 1. As a result, recovery will treat it as a clean array. All recovering sectors are skipped. Original device is replaced with the not-recovered spare. mdadm -C /dev/md0 -l10 -n4 -pn2 /dev/loop[0123] mdadm /dev/md0 -a /dev/loop4 mdadm /dev/md0 --replace /dev/loop0 mdadm -S /dev/md0 # stop array during recovery mdadm -A /dev/md0 /dev/loop[01234] After reassemble, you can see recovery go on, but it completes immediately. In fact, recovery is not actually processed. To solve this problem, we just add the missing logics for replacment spares. (In raid1.c or raid5.c, they have already been checked.) Reported-by:

BugLink: https://bugs.launchpad.net/bugs/1792377 [ Upstream commit 70c3c8cb ] If isoc split in transfer with no data (the length of DATA0 packet is zero), we can't simply return immediately. Because the DATA0 can be the first transaction or the second transaction for the isoc split in transaction. If the DATA0 packet with no data is in the first transaction, we can return immediately. But if the DATA0 packet with no data is in the second transaction of isoc split in transaction sequence, we need to increase the qtd->isoc_frame_index and giveback urb to device driver if needed, otherwise, the MDATA packet will be lost. A typical test case is that connect the dwc2 controller with an usb hs Hub (GL852G-12), and plug an usb fs audio device (Plantronics headset) into the downstream port of Hub. Then use the usb mic to record, we can find noise when playback. In the case, the isoc split in transaction sequence like this: - SSPLIT IN transaction - CSPLIT IN transaction - MDATA packet (176 bytes) - CSPLIT IN transaction - DATA0 packet (0 byte) This patch use both the length of DATA0 and qtd->isoc_split_offset to check if the DATA0 is in the second transaction.

This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped. Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1792377 [ Upstream commit 9ce7bc03 ] It is a waste of memory to use a full "struct netns_sysctl_ipv6" while only one pointer is really used, considering netns_sysctl_ipv6 keeps growing. Also, since "struct netns_frags" has cache line alignment, it is better to move the frags_hdr pointer outside, otherwise we spend a full cache line for this pointer. This saves 192 bytes of memory per netns. Fixes: c038a767 ("ipv6: add a new namespace for nf_conntrack_reasm") Signed-off-by:
