There has been a nasty yet subtle maple tree corruption bug that appears to have been in existence since the inception of the algorithm. This bug seems far more likely to happen since commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()"), which is the point at which reports started to be submitted concerning this bug. We were made definitely aware of the bug thanks to the kind efforts of Bert Karwatzki who helped enormously in my being able to track this down and identify the cause of it. The bug arises when an attempt is made to perform a spanning store across two leaf nodes, where the right leaf node is the rightmost child of the shared parent, AND the store completely consumes the right-mode node. This results in mas_wr_spanning_store() mitakenly duplicating the new and existing entries at the maximum pivot within the range, and thus maple tree corruption. The fix patch corrects this by detecting this scenario and disallowing the mistaken duplicate copy. The fix patch commit message goes into great detail as to how this occurs. This series also includes a test which reliably reproduces the issue, and asserts that the fix works correctly. Bert has kindly tested the fix and confirmed it resolved his issues. Also Mikhail Gavrilov kindly reported what appears to be precisely the same bug, which this fix should also resolve. This patch (of 2): There has been a subtle bug present in the maple tree implementation from its inception. This arises from how stores are performed - when a store occurs, it will overwrite overlapping ranges and adjust the tree as necessary to accommodate this. A range may always ultimately span two leaf nodes. In this instance we walk the two leaf nodes, determine which elements are not overwritten to the left and to the right of the start and end of the ranges respectively and then rebalance the tree to contain these entries and the newly inserted one. This kind of store is dubbed a 'spanning store' and is implemented by mas_wr_spanning_store(). In order to reach this stage, mas_store_gfp() invokes mas_wr_preallocate(), mas_wr_store_type() and mas_wr_walk() in turn to walk the tree and update the object (mas) to traverse to the location where the write should be performed, determining its store type. When a spanning store is required, this function returns false stopping at the parent node which contains the target range, and mas_wr_store_type() marks the mas->store_type as wr_spanning_store to denote this fact. When we go to perform the store in mas_wr_spanning_store(), we first determine the elements AFTER the END of the range we wish to store (that is, to the right of the entry to be inserted) - we do this by walking to the NEXT pivot in the tree (i.e. r_mas.last + 1), starting at the node we have just determined contains the range over which we intend to write. We then turn our attention to the entries to the left of the entry we are inserting, whose state is represented by l_mas, and copy these into a 'big node', which is a special node which contains enough slots to contain two leaf node's worth of data. We then copy the entry we wish to store immediately after this - the copy and the insertion of the new entry is performed by mas_store_b_node(). After this we copy the elements to the right of the end of the range which we are inserting, if we have not exceeded the length of the node (i.e. r_mas.offset <= r_mas.end). Herein lies the bug - under very specific circumstances, this logic can break and corrupt the maple tree. Consider the following tree: Height 0 Root Node / \ pivot = 0xffff / \ pivot = ULONG_MAX / \ 1 A [-----] ... / \ pivot = 0x4fff / \ pivot = 0xffff / \ 2 (LEAVES) B [-----] [-----] C ^--- Last pivot 0xffff. Now imagine we wish to store an entry in the range [0x4000, 0xffff] (note that all ranges expressed in maple tree code are inclusive): 1. mas_store_gfp() descends the tree, finds node A at <=0xffff, then determines that this is a spanning store across nodes B and C. The mas state is set such that the current node from which we traverse further is node A. 2. In mas_wr_spanning_store() we try to find elements to the right of pivot 0xffff by searching for an index of 0x10000: - mas_wr_walk_index() invokes mas_wr_walk_descend() and mas_wr_node_walk() in turn. - mas_wr_node_walk() loops over entries in node A until EITHER it finds an entry whose pivot equals or exceeds 0x10000 OR it reaches the final entry. - Since no entry has a pivot equal to or exceeding 0x10000, pivot 0xffff is selected, leading to node C. - mas_wr_walk_traverse() resets the mas state to traverse node C. We loop around and invoke mas_wr_walk_descend() and mas_wr_node_walk() in turn once again. - Again, we reach the last entry in node C, which has a pivot of 0xffff. 3. We then copy the elements to the left of 0x4000 in node B to the big node via mas_store_b_node(), and insert the new [0x4000, 0xffff] entry too. 4. We determine whether we have any entries to copy from the right of the end of the range via - and with r_mas set up at the entry at pivot 0xffff, r_mas.offset <= r_mas.end, and then we DUPLICATE the entry at pivot 0xffff. 5. BUG! The maple tree is corrupted with a duplicate entry. This requires a very specific set of circumstances - we must be spanning the last element in a leaf node, which is the last element in the parent node. spanning store across two leaf nodes with a range that ends at that shared pivot. A potential solution to this problem would simply be to reset the walk each time we traverse r_mas, however given the rarity of this situation it seems that would be rather inefficient. Instead, this patch detects if the right hand node is populated, i.e. has anything we need to copy. We do so by only copying elements from the right of the entry being inserted when the maximum value present exceeds the last, rather than basing this on offset position. The patch also updates some comments and eliminates the unused bool return value in mas_wr_walk_index(). The work performed in commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()") seems to have made the probability of this event much more likely, which is the point at which reports started to be submitted concerning this bug. The motivation for this change arose from Bert Karwatzki's report of encountering mm instability after the release of kernel v6.12-rc1 which, after the use of CONFIG_DEBUG_VM_MAPLE_TREE and similar configuration options, was identified as maple tree corruption. After Bert very generously provided his time and ability to reproduce this event consistently, I was able to finally identify that the issue discussed in this commit message was occurring for him.

[PATCH 2/4] xhci: Mitigate failed set dequeue pointer commands

by Mathias Nyman

Avoid xHC host from processing a cancelled URB by always turning cancelled URB TDs into no-op TRBs before queuing a 'Set TR Deq' command. If the command fails then xHC will start processing the cancelled TD instead of skipping it once endpoint is restarted, causing issues like Babble error. This is not a complete solution as a failed 'Set TR Deq' command does not guarantee xHC TRB caches are cleared.

[PATCH 5.10 0/1] iommu/amd: Prepare for multiple DMA domain types

by Daniil Dulov

Svacer reports possible dereference of a NULL-pointer in amd_iommu_probe_finalize(). The problem is present in 5.10 stable release and can be fixed by the following upstream patch. In order to apply this patch, the incoming changes had to be manually accepted. This action was necessary due to some differences in the code of amd_iommu_probe_finalize() of the upstream version and 5.10 version of the kernel.

A commit adding back the stopping of tx on port shutdown failed to add back the locking which had also been removed by commit e83766334f96 ("tty: serial: qcom_geni_serial: No need to stop tx/rx on UART shutdown"). Holding the port lock is needed to serialise against the console code, which may update the interrupt enable register and access the port state.

There has been a nasty yet subtle maple tree corruption bug that appears to have been in existence since the inception of the algorithm. This bug seems far more likely to happen since commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()"), which is the point at which reports started to be submitted concerning this bug. We were made definitely aware of the bug thanks to the kind efforts of Bert Karwatzki who helped enormously in my being able to track this down and identify the cause of it. The bug arises when an attempt is made to perform a spanning store across two leaf nodes, where the right leaf node is the rightmost child of the shared parent, AND the store completely consumes the right-mode node. This results in mas_wr_spanning_store() mitakenly duplicating the new and existing entries at the maximum pivot within the range, and thus maple tree corruption. The fix patch corrects this by detecting this scenario and disallowing the mistaken duplicate copy. The fix patch commit message goes into great detail as to how this occurs. This series also includes a test which reliably reproduces the issue, and asserts that the fix works correctly. Bert has kindly tested the fix and confirmed it resolved his issues. Also Mikhail Gavrilov kindly reported what appears to be precisely the same bug, which this fix should also resolve. This patch (of 2): There has been a subtle bug present in the maple tree implementation from its inception. This arises from how stores are performed - when a store occurs, it will overwrite overlapping ranges and adjust the tree as necessary to accommodate this. A range may always ultimately span two leaf nodes. In this instance we walk the two leaf nodes, determine which elements are not overwritten to the left and to the right of the start and end of the ranges respectively and then rebalance the tree to contain these entries and the newly inserted one. This kind of store is dubbed a 'spanning store' and is implemented by mas_wr_spanning_store(). In order to reach this stage, mas_store_gfp() invokes mas_wr_preallocate(), mas_wr_store_type() and mas_wr_walk() in turn to walk the tree and update the object (mas) to traverse to the location where the write should be performed, determining its store type. When a spanning store is required, this function returns false stopping at the parent node which contains the target range, and mas_wr_store_type() marks the mas->store_type as wr_spanning_store to denote this fact. When we go to perform the store in mas_wr_spanning_store(), we first determine the elements AFTER the END of the range we wish to store (that is, to the right of the entry to be inserted) - we do this by walking to the NEXT pivot in the tree (i.e. r_mas.last + 1), starting at the node we have just determined contains the range over which we intend to write. We then turn our attention to the entries to the left of the entry we are inserting, whose state is represented by l_mas, and copy these into a 'big node', which is a special node which contains enough slots to contain two leaf node's worth of data. We then copy the entry we wish to store immediately after this - the copy and the insertion of the new entry is performed by mas_store_b_node(). After this we copy the elements to the right of the end of the range which we are inserting, if we have not exceeded the length of the node (i.e. r_mas.offset <= r_mas.end). Herein lies the bug - under very specific circumstances, this logic can break and corrupt the maple tree. Consider the following tree: Height 0 Root Node / \ pivot = 0xffff / \ pivot = ULONG_MAX / \ 1 A [-----] ... / \ pivot = 0x4fff / \ pivot = 0xffff / \ 2 (LEAVES) B [-----] [-----] C ^--- Last pivot 0xffff. Now imagine we wish to store an entry in the range [0x4000, 0xffff] (note that all ranges expressed in maple tree code are inclusive): 1. mas_store_gfp() descends the tree, finds node A at <=0xffff, then determines that this is a spanning store across nodes B and C. The mas state is set such that the current node from which we traverse further is node A. 2. In mas_wr_spanning_store() we try to find elements to the right of pivot 0xffff by searching for an index of 0x10000: - mas_wr_walk_index() invokes mas_wr_walk_descend() and mas_wr_node_walk() in turn. - mas_wr_node_walk() loops over entries in node A until EITHER it finds an entry whose pivot equals or exceeds 0x10000 OR it reaches the final entry. - Since no entry has a pivot equal to or exceeding 0x10000, pivot 0xffff is selected, leading to node C. - mas_wr_walk_traverse() resets the mas state to traverse node C. We loop around and invoke mas_wr_walk_descend() and mas_wr_node_walk() in turn once again. - Again, we reach the last entry in node C, which has a pivot of 0xffff. 3. We then copy the elements to the left of 0x4000 in node B to the big node via mas_store_b_node(), and insert the new [0x4000, 0xffff] entry too. 4. We determine whether we have any entries to copy from the right of the end of the range via - and with r_mas set up at the entry at pivot 0xffff, r_mas.offset <= r_mas.end, and then we DUPLICATE the entry at pivot 0xffff. 5. BUG! The maple tree is corrupted with a duplicate entry. This requires a very specific set of circumstances - we must be spanning the last element in a leaf node, which is the last element in the parent node. spanning store across two leaf nodes with a range that ends at that shared pivot. A potential solution to this problem would simply be to reset the walk each time we traverse r_mas, however given the rarity of this situation it seems that would be rather inefficient. Instead, this patch detects if the right hand node is populated, i.e. has anything we need to copy. We do so by only copying elements from the right of the entry being inserted when the maximum value present exceeds the last, rather than basing this on offset position. The patch also updates some comments and eliminates the unused bool return value in mas_wr_walk_index(). The work performed in commit f8d112a4e657 ("mm/mmap: avoid zeroing vma tree in mmap_region()") seems to have made the probability of this event much more likely, which is the point at which reports started to be submitted concerning this bug. The motivation for this change arose from Bert Karwatzki's report of encountering mm instability after the release of kernel v6.12-rc1 which, after the use of CONFIG_DEBUG_VM_MAPLE_TREE and similar configuration options, was identified as maple tree corruption. After Bert very generously provided his time and ability to reproduce this event consistently, I was able to finally identify that the issue discussed in this commit message was occurring for him.

[PATCH 5.15.y 5.10.y 5.4.y] wifi: mac80211: fix potential key use-after-free

by Sherry Yang

From: Johannes Berg <johannes.berg(a)intel.com> [ Upstream commit 31db78a4923ef5e2008f2eed321811ca79e7f71b ] When ieee80211_key_link() is called by ieee80211_gtk_rekey_add() but returns 0 due to KRACK protection (identical key reinstall), ieee80211_gtk_rekey_add() will still return a pointer into the key, in a potential use-after-free. This normally doesn't happen since it's only called by iwlwifi in case of WoWLAN rekey offload which has its own KRACK protection, but still better to fix, do that by returning an error code and converting that to success on the cfg80211 boundary only, leaving the error for bad callers of ieee80211_gtk_rekey_add().

[PATCH 6.1.y] nvme: fix metadata handling in nvme-passthrough

by Puranjay Mohan

[ Upstream commit 7c2fd76048e95dd267055b5f5e0a48e6e7c81fd9 ] On an NVMe namespace that does not support metadata, it is possible to send an IO command with metadata through io-passthru. This allows issues like [1] to trigger in the completion code path. nvme_map_user_request() doesn't check if the namespace supports metadata before sending it forward. It also allows admin commands with metadata to be processed as it ignores metadata when bdev == NULL and may report success. Reject an IO command with metadata when the NVMe namespace doesn't support it and reject an admin command if it has metadata.
