[ Upstream commit b38b298a ] __hyp_call_panic_nvhe contains inline assembly which did not declare its dependency on the __hyp_panic_string symbol. The static-declared string has previously been kept alive because of a use in __hyp_call_panic_vhe. Fix this in preparation for separating the source files between VHE and nVHE when the two users land in two different compilation units. The static variable otherwise gets dropped when compiling the nVHE source file, causing an undefined symbol linker error later. Signed-off-by:

[ Upstream commit 709ed1bc ] The Intel uncore driver may claim some of the pci ids from ie31200 which means that the ie31200 edac driver will not initialize them as part of pci_register_driver(). Let's add a fallback for this case to 'pci_get_device()' to get a reference on the device such that it can still be configured. This is similar in approach to other edac drivers. Signed-off-by:

[ Upstream commit fa996773 ] Make sure the delayed work stopped before releasing the resources. cancel_delayed_work_sync() will only guarantee that the work finishes executing if the work is already in the ->worklist. That means after the cancel_delayed_work_sync() returns, it will leave the work requeued if it was rearmed at the end. That can lead to a use after free once the work struct is freed. Fix it by flushing the delayed work instead of trying to cancel it, and ensure that the work doesn't rearm if the mdsc is stopping. URL: https://tracker.ceph.com/issues/46293Signed-off-by:

[ Upstream commit a7f8b1c2 ] The incoming qgroup reserved space timing will move the data reservation to ordered extent completely. However in btrfs_punch_hole_lock_range() will call btrfs_invalidate_page(), which will clear QGROUP_RESERVED bit for the range. In current stage it's OK, but if we're making ordered extents handle the reserved space, then btrfs_punch_hole_lock_range() can clear the QGROUP_RESERVED bit before we submit ordered extent, leading to qgroup reserved space leakage. So here change the timing to make reserve data space after btrfs_punch_hole_lock_range(). The new timing is fine for either current code or the new code. Reviewed-by:

[ Upstream commit 5656bb38 ] The timer fixed interval period pulse generator register is used to generate periodic pulses. The down count register loads the value programmed in the fixed period interval (FIPER). At every tick of the timer accumulator overflow, the counter decrements by the value of TMR_CTRL[TCLK_PERIOD]. It generates a pulse when the down counter value reaches zero. It reloads the down counter in the cycle following a pulse. To use the TMR_FIPER register to generate desired periodic pulses. The value should programmed is, desired_period - tclk_period Current tmr-fiper2 value is to generate 100us periodic pulses. (But the value should have been 99995, not 99990. The tclk_period is 5.) This patch is to generate 1 second periodic pulses with value 999999995 programmed which is more desired by user. Signed-off-by:

[ Upstream commit 96355d5a ] In tracking down a problem in this patchset, I discovered we are reclaiming dirty stale inodes. This wasn't discovered until inodes were always attached to the cluster buffer and then the rcu callback that freed inodes was assert failing because the inode still had an active pointer to the cluster buffer after it had been reclaimed. Debugging the issue indicated that this was a pre-existing issue resulting from the way the inodes are handled in xfs_inactive_ifree. When we free a cluster buffer from xfs_ifree_cluster, all the inodes in cache are marked XFS_ISTALE. Those that are clean have nothing else done to them and so eventually get cleaned up by background reclaim. i.e. it is assumed we'll never dirty/relog an inode marked XFS_ISTALE. On journal commit dirty stale inodes as are handled by both buffer and inode log items to run though xfs_istale_done() and removed from the AIL (buffer log item commit) or the log item will simply unpin it because the buffer log item will clean it. What happens to any specific inode is entirely dependent on which log item wins the commit race, but the result is the same - stale inodes are clean, not attached to the cluster buffer, and not in the AIL. Hence inode reclaim can just free these inodes without further care. However, if the stale inode is relogged, it gets dirtied again and relogged into the CIL. Most of the time this isn't an issue, because relogging simply changes the inode's location in the current checkpoint. Problems arise, however, when the CIL checkpoints between two transactions in the xfs_inactive_ifree() deferops processing. This results in the XFS_ISTALE inode being redirtied and inserted into the CIL without any of the other stale cluster buffer infrastructure being in place. Hence on journal commit, it simply gets unpinned, so it remains dirty in memory. Everything in inode writeback avoids XFS_ISTALE inodes so it can't be written back, and it is not tracked in the AIL so there's not even a trigger to attempt to clean the inode. Hence the inode just sits dirty in memory until inode reclaim comes along, sees that it is XFS_ISTALE, and goes to reclaim it. This reclaiming of a dirty inode caused use after free, list corruptions and other nasty issues later in this patchset. Hence this patch addresses a violation of the "never log XFS_ISTALE inodes" caused by the deferops processing rolling a transaction and relogging a stale inode in xfs_inactive_free. It also adds a bunch of asserts to catch this problem in debug kernels so that we don't reintroduce this problem in future. Reproducer for this issue was generic/558 on a v4 filesystem.

[ Upstream commit 03dbfe06 ] When vports are deleted, it is observed that there is memory/kthread leakage as the vport isn't fully being released. There is a shost reference taken in scsi_add_host_dma that is not released during scsi_remove_host. It was noticed that other drivers resolve this by doing a scsi_host_put after calling scsi_remove_host. The vport_delete routine is taking two references one that corresponds to an access to the scsi_host in the vport_delete routine and another that is released after the adapter mailbox command completes that destroys the VPI that corresponds to the vport. Remove one of the references taken such that the second reference that is put will complete the missing scsi_add_host_dma reference and the shost will be terminated.

[ Upstream commit d3e3d2be ] Unlike the other instances which represent a complete loss of consistency within the rcache mechanism itself, or a fundamental and obvious misconfiguration by an IOMMU driver, the BUG_ON() in iova_magazine_free_pfns() can be provoked at more or less any time in a "spooky action-at-a-distance" manner by any old device driver passing nonsense to dma_unmap_*() which then propagates through to queue_iova(). Not only is this well outside the IOVA layer's control, it's also nowhere near fatal enough to justify panicking anyway - all that really achieves is to make debugging the offending driver more difficult. Let's simply WARN and otherwise ignore bogus PFNs. Reported-by:

[ Upstream commit 5a0c256d ] If tcmu_handle_completions() has to process a padding shorter than sizeof(struct tcmu_cmd_entry), the current call to tcmu_flush_dcache_range() with sizeof(struct tcmu_cmd_entry) as length param is wrong and causes crashes on e.g. ARM, because tcmu_flush_dcache_range() in this case calls flush_dcache_page(vmalloc_to_page(start)); with start being an invalid address above the end of the vmalloc'ed area. The fix is to use the minimum of remaining ring space and sizeof(struct tcmu_cmd_entry) as the length param. The patch was tested on kernel 4.19.118.

[ Upstream commit b431ef83 ] We make an assumption that a debugfs directory exists, but since this can fail ensure it exists before allowing blktrace setup to complete. Otherwise we end up stuffing blktrace files on the debugfs root directory. In the worst case scenario this *in theory* can create an eventual panic *iff* in the future a similarly named file is created prior on the debugfs root directory. This theoretical crash can happen due to a recursive removal followed by a specific dentry removal. This doesn't fix any known crash, however I have seen the files go into the main debugfs root directory in cases where the debugfs directory was not created due to other internal bugs with blktrace now fixed. blktrace is also completely useless without this directory, so this ensures to userspace we only setup blktrace if the kernel can stuff files where they are supposed to go into. debugfs directory creations typically aren't checked for, and we have maintainers doing sweep removals of these checks, but since we need this check to ensure proper userspace blktrace functionality we make sure to annotate the justification for the check.
