| * | irqchip/gic-v3: Init SRE before poking sysregsMark Rutland2024-08-231-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GICv3 driver pokes GICv3 system registers in gic_prio_init() before gic_cpu_sys_reg_init() ensures that GICv3 system registers have been enabled by writing to ICC_SRE_EL1.SRE. On arm64 this is benign as has_useable_gicv3_cpuif() runs earlier during cpufeature detection, and this enables the GICv3 system registers. On 32-bit arm when booting on an FVP using the boot-wrapper, the accesses in gic_prio_init() end up being UNDEFINED and crashes the kernel during boot. This is a regression introduced by the addition of gic_prio_init(). Fix this by factoring out the SRE initialization into a new function and calling it early in the three paths where SRE may not have been initialized: (1) gic_init_bases(), before the primary CPU pokes GICv3 sysregs in gic_prio_init(). (2) gic_starting_cpu(), before secondary CPUs initialize GICv3 sysregs in gic_cpu_init(). (3) gic_cpu_pm_notifier(), before CPUs re-initialize GICv3 sysregs in gic_cpu_sys_reg_init().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recently established lock ordering mandates that the per-VM vmapp_lock is acquired before taking the per-VPE lock. As it turns out, its_vpe_set_affinity() takes the VPE lock, and then calls into its_send_vmovp(), which itself takes the vmapp lock. Obviously, this is a lock order violation. As its_send_vmovp() is only called from its_vpe_set_affinity(), hoist the vmapp locking from the former into the latter, restoring the expected order.

Converting the sun4i timer to a platform driver does not work either because the D1 does not have a SBI timer available so early boot hangs. See the 'Closes:' link for deeper analysis. The real fix requires enabling the SBI time extension in the platform firmware (OpenSBI) and convert sun4i_timer into platform driver. Unfortunately, the real fix involves changing multiple places and can't be achieved in a short duration and aside of that requires users to update firmware. As a work-around, retrofit PLIC probing such that the PLIC is probed early only for the Allwinner D1 platform and probed as a regular platform driver for rest of the RISC-V platforms. In the process, partially revert some of the previous changes because the PLIC device pointer is not available in all probing paths.

For example: xfs_io -f -t -c "pwrite -S 0x41 0 4k" \ -c "pwrite -S 0x42 4k 4k" \ -c "fzero 0 4k" \ -c "pread -v 0 8k" /xfstest.test/foo will write two 4KiB blocks of data, which get buffered in the pagecache, and then fallocate() is used to clear the first 4KiB block on the server - but we don't flush the data first, which means the EOF position on the server is wrong, and so the FSCTL_SET_ZERO_DATA RPC fails (and xfs_io ignores the error), but then when we try to read it, we see the old data. Fix this by preflushing any part of the target region that above the server's idea of the EOF position to force the server to update its EOF position. Note, however, that we don't want to simply expand the file by moving the EOF before doing the FSCTL_SET_ZERO_DATA[*] because someone else might see the zeroed region or if the RPC fails we then have to try to clean it up or risk getting corruption. [*] And we have to move the EOF first otherwise FSCTL_SET_ZERO_DATA won't do what we want. This fixes the generic/008 xfstest. [!] Note: A better way to do this might be to split the operation into two parts: we only do FSCTL_SET_ZERO_DATA for the part of the range below the server's EOF and then, if that worked, invalidate the buffered pages for the part above the range.

| * | | netfs, cifs: Fix handling of short DIO readDavid Howells2024-08-283-10/+21

This can be tested by doing a DIO read of a file where the size of read is larger than the size of the file. When it crosses the EOF, it gets a short read and this gets retried, and in the case of cifs, the retry read fails, with the failure being translated to ENODATA. Fix this by the following means: (1) Add a flag, NETFS_SREQ_HIT_EOF, for the filesystem to set when it detects that the read did hit the EOF. (2) Make the netfslib read assessment stop processing subrequests when it encounters one with that flag set. (3) Return rreq->transferred, the accumulated contiguous amount read to that point, to userspace for a DIO read. (4) Make cifs set the flag and clear the error if the read RPC returned ENODATA. (5) Make cifs set the flag and clear the error if a short read occurred without error and the read-to file position is now at the remote inode size.

This causes the retried read to be done with zero credits which causes the server to reject it with STATUS_INVALID_PARAMETER. This is a problem for a DIO read that is requested that would go over the EOF. The short read will be retried, causing EINVAL to be returned to the user when it fails. Fix this by making cifs_req_issue_read() negotiate new credits if retrying (NETFS_SREQ_RETRYING now gets set in the read side as well as the write side in this instance). This isn't sufficient, however: the new credits might not be sufficient to complete the remainder of the read, so also add an additional field, rreq->actual_len, that holds the actual size of the op we want to perform without having to alter subreq->len. We then rely on repeated short reads being retried until we finish the read or reach the end of file and make a zero-length read. Also fix a couple of places where the subrequest start and length need to be altered by the amount so far transferred when being used.

It's undetermined if it's write calls are being dropped or dirty folios. Further testing, via minimizing the original patch to just the change that skips the inode lock on non appends/truncates, reveals that it really is just not taking the inode lock that causes the corruption: it has nothing to do with the other logic changes for preserving write atomicity in corner cases. It's also kernel config dependent: it doesn't reproduce with the minimal kernel config that ktest uses, but it does reproduce with nixos's distro config. Bisection the kernel config initially pointer the finger at page migration or compaction, but it appears that was erroneous; we haven't yet determined what kernel config option actually triggers it. Sadly it appears this will have to be reverted since we're getting too close to release and my plate is full, but we'd _really_ like to fully debug it. My suspicion is that this patch is exposing a preexisting bug - the inode lock actually covers very little in IO paths, and we have a different lock (the pagecache add lock) that guards against races with truncate here.

However one or both extents may have been trimmed (or merged) and they might not have the same disk offset: it corrects for this by subtracting the key offset and the checksum entry offset. However, this failed when an extent was immediately partially overwritten, and the new overwrite was allocated the next adjacent disk space. Normally, with compression off, this would never cause a bug, since the new extent would have to be immediately after the old extent for the pointer offsets to match, and the rebalance index update path is not looking for an extent outside the range of the extent it moved. However with compression enabled, extents take up less space on disk than they do in the btree index space - and spuriously matching after partial overwrite is possible. To fix this, add a secondary check, that strictly checks that the regions pointed to on disk overlap. https://github.com/koverstreet/bcachefs/issues/717 Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

The removal of dummy empty entry in memblock caused this check to fail because now memblock.reserved.cnt is initialized to 0.

If VIDIOC_QBUF is executed before VIDIOC_STREAMON, we can only depend on uvc_video_complete() to queue pump work. However, this requires some free requests in req_ready list. If req_ready list is empty all the time, pump work will never be queued and video datas will never be pumped to usb controller. Actually, this situation could happen when run uvc-gadget with static image: $ ./uvc-gadget -i 1080p.jpg uvc.0 When capture image from this device, the user app will always block there. The issue is uvc driver has queued video buffer before streamon, but the req_ready list is empty all the time after streamon. This will queue pump work in uvcg_video_enable() to fill some request to req_ready list so the uvc device could work properly.

The problem arises from the following sequence. 1. In dwc3_gadget_suspend, there is a chance of a timeout when moving the USB core to the halt state after clearing the run/stop bit by software. 2. In dwc3_core_exit, the event buffer is cleared regardless of the USB core's status, which may lead to an SMMU faults and other memory issues. if the USB core tries to access the event buffer address. To prevent this hardware quirk on Exynos platforms, this commit ensures that the event buffer address is not cleared by software when the USB core is active during runtime suspend by checking its status before clearing the buffer address.

When the disk is processing the format command, the system does not submit other commands to the disk. Therefore, the system attempts to suspend the disk again and sends the SYNCHRONIZE CACHE command. However, the SYNCHRONIZE CACHE command will fail because the disk is in the formatting process. This will cause the runtime_status of the disk to error and it is difficult for user to recover it.
