BugLink: https://bugs.launchpad.net/bugs/1860681 commit ad6bf88a upstream. Logical block size has type unsigned short. That means that it can be at most 32768. However, there are architectures that can run with 64k pages (for example arm64) and on these architectures, it may be possible to create block devices with 64k block size. For exmaple (run this on an architecture with 64k pages): Mount will fail with this error because it tries to read the superblock using 2-sector access: device-mapper: writecache: I/O is not aligned, sector 2, size 1024, block size 65536 EXT4-fs (dm-0): unable to read superblock This patch changes the logical block size from unsigned short to unsigned int to avoid the overflow.

BugLink: https://bugs.launchpad.net/bugs/1860681 commit f5ae2ea6 upstream. Intel Software Developer's Manual, volume 3, chapter 9.11.6 says: "Note that the microcode update must be aligned on a 16-byte boundary and the size of the microcode update must be 1-KByte granular" When early-load Intel microcode is loaded from initramfs, userspace tool 'iucode_tool' has already 16-byte aligned those microcode bits in that initramfs image. Image that was created something like this: iucode_tool --write-earlyfw=FOO.cpio microcode-files... However, when early-load Intel microcode is loaded from built-in firmware BLOB using CONFIG_EXTRA_FIRMWARE= kernel config option, that 16-byte alignment is not guaranteed. Fix this by forcing all built-in firmware BLOBs to 16-byte alignment. [ If we end up having other firmware with much bigger alignment requirements, we might need to introduce some method for the firmware to specify it, this is the minimal "just increase the alignment a bit to account for this one special case" patch - Linus ] Signed-off-by:

This patch applies the missing q->timer_mutex lock while accessing the timer object as well as a slight code change to adapt the standard coding style.

BugLink: https://bugs.launchpad.net/bugs/1860681 [ Upstream commit 397eac17 ] If journal is dirty when mount, it will be replayed but jbd2 sb log tail cannot be updated to mark a new start because journal->j_flag has already been set with JBD2_ABORT first in journal_init_common. When a new transaction is committed, it will be recored in block 1 first(journal->j_tail is set to 1 in journal_reset). If emergency restart happens again before journal super block is updated unfortunately, the new recorded trans will not be replayed in the next mount. The following steps describe this procedure in detail. 1. mount and touch some files 2. these transactions are committed to journal area but not checkpointed 3. emergency restart 4. mount again and its journals are replayed 5. journal super block's first s_start is 1, but its s_seq is not updated 6. touch a new file and its trans is committed but not checkpointed 7. emergency restart again 8. mount and journal is dirty, but trans committed in 6 will not be replayed. This exception happens easily when this lun is used by only one node. If it is used by multi-nodes, other node will replay its journal and its journal super block will be updated after recovery like what this patch does. ocfs2_recover_node->ocfs2_replay_journal. The following jbd2 journal can be generated by touching a new file after journal is replayed, and seq 15 is the first valid commit, but first seq is 13 in journal super block. logdump: Block 0: Journal Superblock Seq: 0 Type: 4 (JBD2_SUPERBLOCK_V2) Blocksize: 4096 Total Blocks: 32768 First Block: 1 First Commit ID: 13 Start Log Blknum: 1 Error: 0 Feature Compat: 0 Feature Incompat: 2 block64 Feature RO compat: 0 Journal UUID: 4ED3822C54294467A4F8E87D2BA4BC36 FS Share Cnt: 1 Dynamic Superblk Blknum: 0 Per Txn Block Limit Journal: 0 Data: 0 Block 1: Journal Commit Block Seq: 14 Type: 2 (JBD2_COMMIT_BLOCK) Block 2: Journal Descriptor Seq: 15 Type: 1 (JBD2_DESCRIPTOR_BLOCK) No. Blocknum Flags 0. 587 none UUID: 00000000000000000000000000000000 1. 8257792 JBD2_FLAG_SAME_UUID 2. 619 JBD2_FLAG_SAME_UUID 3. 24772864 JBD2_FLAG_SAME_UUID 4. 8257802 JBD2_FLAG_SAME_UUID 5. 513 JBD2_FLAG_SAME_UUID JBD2_FLAG_LAST_TAG ...

BugLink: https://bugs.launchpad.net/bugs/1860681 commit fed8d8c7 upstream. The driver does the wrong thing when cs_change is set on a non-last xfer in a message. When cs_change is set, the driver deactivates the CS and leaves it off until a later xfer again has cs_change set whereas it should be briefly toggling CS off and on again. This patch brings the behaviour of the driver back in line with the documentation and common sense. The delay of 10 us is the same as is used by the default spi_transfer_one_message() function in spi.c.

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 74887542 upstream. Per Documentation/DMA-API-HOWTO.txt, To unmap a scatterlist, just call: dma_unmap_sg(dev, sglist, nents, direction); .. note:: The 'nents' argument to the dma_unmap_sg call must be the _same_ one you passed into the dma_map_sg call, it should _NOT_ be the 'count' value _returned_ from the dma_map_sg call. However in the driver, priv->nent is directly assigned with value returned from dma_map_sg, and dma_unmap_sg use priv->nent for unmap, this breaks the API usage. So introduce a new entry orig_nent to remember 'nents'. Fixes: da3564ee ("pch_uart: add multi-scatter processing") Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 529244bd upstream. Doing an add/remove/add on a SCSI device in an enclosure leads to an oops caused by poisoned values in the enclosure device list pointers. The reason is because we are keeping the enclosure device across the enclosed device add/remove/add but the current code is doing a device_add/device_del/device_add on it. This is the wrong thing to do in sysfs, so fix it by not doing a device_del on the enclosure device simply because of a hot remove of the drive in the slot.

BugLink: https://bugs.launchpad.net/bugs/1860681 commit d935bd50 upstream. When a GPIO offset in a lookup table is out-of-range, the printed error message (1) does not include the actual out-of-range value, and (2) contains an off-by-one error in the upper bound. Avoid user confusion by also printing the actual GPIO offset, and correcting the upper bound of the range. While at it, use "%u" for unsigned int. Sample impact: -requested GPIO 0 is out of range [0..32] for chip e6052000.gpio +requested GPIO 0 (45) is out of range [0..31] for chip e6052000.gpio Fixes: 2a3cf6a3 ("gpiolib: return -ENOENT if no GPIO mapping exists") Signed-off-by:

Instead of trying to allocate pages with GFP_USER in add_ballooned_pages() check the available free memory via si_mem_available(). GFP_USER is far less limiting memory exhaustion than the test via si_mem_available(). This will avoid dom0 running out of memory due to excessive foreign page mappings especially on ARM and on x86 in PVH mode, as those don't have a pre-ballooned area which can be used for foreign mappings. As the normal ballooning suffers from the same problem don't balloon down more than si_mem_available() pages in one iteration. At the same time limit the default maximum number of retries.

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 34501219 upstream. LINE6 drivers allocate the buffers based on the value returned from usb_maxpacket() calls. The manipulated device may return zero for this, and this results in the kmalloc() with zero size (and it may succeed) while the other part of the driver code writes the packet data with the fixed size -- which eventually overwrites. This patch adds a simple sanity check for the invalid buffer size for avoiding that problem. Reported-by: syzbot+219f00fb49874dcaea17@syzkaller.appspotmail.com Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 6e41e225 upstream. The syzbot fuzzer found a bug in the p54 USB wireless driver. The issue involves a race between disconnect and the firmware-loader callback routine, and it has several aspects. One big problem is that when the firmware can't be loaded, the callback routine tries to unbind the driver from the USB _device_ (by calling device_release_driver) instead of from the USB _interface_ to which it is actually bound (by calling usb_driver_release_interface). The race involves access to the private data structure. The driver's disconnect handler waits for a completion that is signalled by the firmware-loader callback routine. As soon as the completion is signalled, you have to assume that the private data structure may have been deallocated by the disconnect handler -- even if the firmware was loaded without errors. However, the callback routine does access the private data several times after that point. Another problem is that, in order to ensure that the USB device structure hasn't been freed when the callback routine runs, the driver takes a reference to it. This isn't good enough any more, because now that the callback routine calls usb_driver_release_interface, it has to ensure that the interface structure hasn't been freed. Finally, the driver takes an unnecessary reference to the USB device structure in the probe function and drops the reference in the disconnect handler. This extra reference doesn't accomplish anything, because the USB core already guarantees that a device structure won't be deallocated while a driver is still bound to any of its interfaces. To fix these problems, this patch makes the following changes: Call usb_driver_release_interface() rather than device_release_driver(). Don't signal the completion until after the important information has been copied out of the private data structure, and don't refer to the private data at all thereafter. Lock udev (the interface's parent) before unbinding the driver instead of locking udev->parent. During the firmware loading process, take a reference to the USB interface instead of the USB device. Don't take an unnecessary reference to the device during probe (and then don't drop it during disconnect). Signed-off-by:

BugLink: https://bugs.launchpad.net/bugs/1860681 commit 3e493173 upstream. The Layer 2 Update frame is used to update bridges when a station roams to another AP even if that STA does not transmit any frames after the reassociation. This behavior was described in IEEE Std 802.11F-2003 as something that would happen based on MLME-ASSOCIATE.indication, i.e., before completing 4-way handshake. However, this IEEE trial-use recommended practice document was published before RSN (IEEE Std 802.11i-2004) and as such, did not consider RSN use cases. Furthermore, IEEE Std 802.11F-2003 was withdrawn in 2006 and as such, has not been maintained amd should not be used anymore. Sending out the Layer 2 Update frame immediately after association is fine for open networks (and also when using SAE, FT protocol, or FILS authentication when the station is actually authenticated by the time association completes). However, it is not appropriate for cases where RSN is used with PSK or EAP authentication since the station is actually fully authenticated only once the 4-way handshake completes after authentication and attackers might be able to use the unauthenticated triggering of Layer 2 Update frame transmission to disrupt bridge behavior. Fix this by postponing transmission of the Layer 2 Update frame from station entry addition to the point when the station entry is marked authorized. Similarly, send out the VLAN binding update only if the STA entry has already been authorized. Signed-off-by:
