The propagate_mnt() functions handles mount propagation when creating mounts and propagates the source mount tree headed by @source_mnt to the destination propagation mount tree @dest_mnt. Unfortunately it contains a bug where it fails to terminate correctly and causes a NULL dereference. While fixing this bug we've gotten confused multiple times due to conflicting or even missing terminology and concepts. So I want to start this with the following clarifications: * The terms "master" or "peer" denote a shared mount. A shared mount belongs to a peer group identified by a peer group id recorded in @shared_mnt->mnt_group_id. Shared mounts within the same peer group have the same peer group id. The peers in a peer group can be reached via @shared_mnt->mnt_share. * Shared mounts may have dependent or "slave" mounts. These are listed on @shared_mnt->mnt_slave_list. Multiple peers in a peer group can have non-empty ->mnt_slave_lists and non-empty mnt_slave_lists of peers don't intersect. Consequently, to ensure all slave mounts of a peer group are visited the ->mnt_slave_lists of all peers in that peer group need to be walked. * A slave mount is a dependent mount that receives propagation from the peers in a peer group it is a slave to. The closest peer group a slave mount receives propagation from can be identified by looking at the peer group id of the ->mnt_master of that slave mount, i.e., by looking at @slave_mnt->mnt_master->mnt_group_id. A slave mount to a peer group pg1 can itself be a peer in another peer group pg2. Such slaves will be called "shared-slave mounts" because they are both slave mounts to pg1 and a shared mount in a peer group pg2. Each shared-slave mount which is a peer in a peer group pg2 can be a slave mount to a different peer group. For example, @shared_slave_1->mnt_group_id = 1 and @shared_slave_2->mnt_group_id = 1 are peers in the peer group with peer group id 2. But @shared_slave_1->mnt_master->mnt_group_id = 2 and @shared_slave_1->mnt_master->mnt_group_id = 3 are slaves to different peer groups; @shared_slave_1 is a slave to peer group 2 and @shared_slave_2 is a slave to peer group 3. A slave that isn't a peer in another peer group, i.e., is not a shared-slave mount will be called a "pure slave mount". * A propagation group denotes the set of mounts consisting of a single peer group pg1 and all slave mounts and shared-slave mounts that receive propagation from this peer group, i.e., whose master is from pg1. Specifically, the boundary of a propagation group ends with its immediate slaves: It only encompasses the peers in that peer group and all slave mounts whose master is a mount in that peer group such that @slave_mnt->mnt_master->mnt_group_id is equal to @shared_mnt->mnt_group_id. IOW, it excludes the slave mounts of peer groups that shared-slave mounts of the peer group form. It makes it easier to talk about a single propagation "level" whereas a propagation tree usually refers to the set of mounts that receive propagation starting from a specific shared mount. For example, for propagate_mnt() a @dest_mnt is the start of a propagation tree. The peers in @dest_mnt's peer group and all slaves whose ->mnt_master points to a peer in @dest_mnt's peer group form a propagation group. The peer group of a shared-slave and the slave mounts whose ->mnt_master points to a peer in the shared-slave mount's peer group form another propagation group. With that out of the way let's get to the actual algorithm. First, propagate_mnt() propagates the @source_mnt tree to all peers in the peer group of @dest_mnt. We know that @dest_mnt is guaranteed to be a shared mount as attach_recursive_mnt() will have verified this for us: for (n = next_peer(dest_mnt); n != dest_mnt; n = next_peer(n)) { ret = propagate_one(n); if (ret) goto out; } Notice, that it doesn't propagate @dest_mnt itself. That is because @dest_mnt is mounted directly in attach_recursive_mnt(). This means that by the time propagate_mnt() is called @source_mnt will not yet have been mounted on @dest_mnt. Consequently, @source_mnt->mnt_parent will still be pointing to it's old parent - when the mount is moved - or to itself when it's a new or bind-mount. So for each peer @m in the peer group of @dest_mnt we create a new copy @child of @source_mnt and mount it @m such that @child->mnt_parent is @m. This is straightforward and no further steps are required. After having finished propagating @source_mnt to the peers in @dest_mnt's peer group propagate_mnt() will propagate @source_mnt to the slaves of the peers in @dest_mnt's peer group: for (m = next_group(dest_mnt, dest_mnt); m; m = next_group(m, dest_mnt)) { /* everything in that slave group */ n = m; do { ret = propagate_one(n); if (ret) goto out; n = next_peer(n); } while (n != m); } The next_group() helper will take care to walk the destination propagation tree by peer groups recursively. For each peer group that receives propagation it ensures that we always find a peer in a peer group before we find any slaves of that peer group. IOW, finding masters before slaves. It is important to remember that propagating the @source_mnt tree to each mount @m in the destination propagation tree simply means that we create and mount a new copy @child of the @source_mnt tree on @m such that @child->mnt_parent is @m. The tricky part is to figure out what the masters of the new copies of @source_mnt will be when mounted on their new parent @m in the destination propagation tree. This is tricky because we must keep track of the last propagation node @m in the destination propagation tree headed by @dest_mnt and the corresponding copy of @source_mnt we created and mounted at @. We track the former in @last_dest and we track the later in @last_source. So with each call to propagate_one() we advance @last_dest and @last_source to @m and @child were @child is the copy of @last_source we created. The easy case is what @m and @last_dest are peers as we know that we can simply copy @last_source without having to figure out what the master for the new copy @child of @last_source needs to be. The hard case is when we're dealing with a slave mount or a new shared-slave mount @m in a destination propagation group. First, we lookup the master of @m. If we haven't descended into a separate propagation group that @dest_mnt propagates to yes then we don't have any marked masters and the relevant master for @m will be @dest_mnt->mnt_master. IOW, we walk the destination master chain all the way back up to @dest_mnt->mnt_master and break: for (n = m; ; n = p) { p = n->mnt_master; if (p == dest_master || IS_MNT_MARKED(p)) break; } For each propagation node @m in the destination propagation tree headed @dest_mnt we can walk up the peer group hierarchy by following the masters @m->mnt_master of @m. Inevitably we will end up either @dest_mnt. One the first slave mount @m of @dest_mnt in @dest_mnt's propagation group no mount is marked yet. So the first iteration sets: n = m; p = n->mnt_master; @p now points to @dest_mnt since that is it's master. We walk up one more level since we don't have any marked mounts. So we end up with n = dest_mnt; p = dest_mnt->mnt_master; Either dest_mnt is a pure shared mount then dest_mnt->mnt_master is NULL or dest_mnt is a shared-slave and dest_mnt->mnt_master points to a master outside the propagation tree we're dealing with. Now we need to figure out the master for the copy of @last_source we're about to create: do { struct mount *parent = last_source->mnt_parent; if (last_source == first_source) break; done = parent->mnt_master == p; if (done && peers(n, parent)) break; last_source = last_source->mnt_master; } while (!done); For the first slave mount of @dest_mnt's peer group we know that @last_source->mnt_parent points to @last_dest. And we know that @last_dest points to the last peer we handled in propagate_mnt()'s peer loop. Consequently, @last_source->mnt_parent->mnt_master points to @last_dest->mnt_master. We also know that @last_dest->mnt_master is either NULL or points to a master outside of the propagation tree: done = parent->mnt_master == p; is trivially true. We also know that for the first slave mount of @dest_mnt that @last_dest either points @dest_mnt itself because it was initialized to: last_dest = dest_mnt; at the beginning of propagate_mnt() or it will point to a peer of @dest_mnt in its peer group. In both cases it is guaranteed that on the first iteration @n and @parent are peers: if (done && peers(n, parent)) break; This means that the master of the copy @child of @last_source we're going to mount at @m needs to be @last_source. And we know that @last_source is set to the last copy we created and mounted at the last destination node @m which was a peer in @dest_mnt's peer group. And since the master of the first destination propagation node @m we handled after handling the peer of @dest_mnt's peer group is @dest_mnt - as it's a slave mount of @dest_mnt - we mark this mount as a master. Although less obvious, the lookup of the correct master for @last_source is premised on the assumption that each copy of @source_mnt that is mounted on top of @m we will allows us to similarly traverse the peer group hierarchy of the destination propagation tree. If we take @last_source which is the copy of @source_mnt we have mounted on @m in previous iteration of propagate_one() then @last_source->mnt_master will point to an earlier copy of @last_source that we mounted at the previous destination propagation node @m. Hence, the first @last_source->mnt_master->mnt_parent will point to @last_dest and @last_dest->mnt_master will be our hook into the master hierarchy of the destination propagation tree headed @dest_mnt. Hence, by walking up @last_source->mnt_master we will walk up the new source destination peer group hierarchy each anchored at a destination propagation node @m in the destination propagation tree headed at @dest_mnt. IOW, the destination propagation tree will be overlayed with copies of @source_mnt. And when we're all done with this the sequence of copies of @source_mnt we mounted on top the destination propagation nodes @m will mirror the propagation of the destination nodes @m. So, for each new destination propagation node @m we use the previous copy of @last_source and previous destination propagation node @last_dest to determine what the master of the new copy of @last_source has to be. And with each destination propagation node @m we mount a copy of @source_mnt on we will mark the peer which is the closest peer that @m receives propagation from in the destination propagation tree. For the next @m we search for a marked master which will be the closest peer group that @m receives propagation from. We store that master in @p and record the previous destination propagation node @n. We then search for this master via @last_source by walking up the master hierarchy based on the last copy of @last_source we mounted on the previous destination propagation node. Ultimately we will hit a master in the source propagation master hierarchy that is mounted on a previous destination propagation node @m. We can access that @m via @last_source->mnt_master->mnt_parent. We will then find a master @last_source->mnt_master->mnt_parent->mnt_master that will correspond to the closest marked peer group master @p we receive propagation from and that we detected earlier. Now, if @last_source->mnt_master->mnt_parent and @n are peers then we know that the new master is the one we just looked up: @last_source. If they aren't peers we know that the new master needs to be @last_source->mnt_master. However, terminating the walk has corner cases... If the closest marked master for a given destination node @m cannot be found by walking up the master hierarchy based on @last_source then we need to terminate the walk when we encounter @source_mnt as this means @source_mnt will be the master of the new copy of @last_source we're about to create. As @last_source might not have a master this would lead to a NULL dereference. So we have to stop the walk when we encounter @source_mnt again. In a way, this happens when we handled the last slave mount that is a slave to a peer group that receives propagation from @dest_mnt's peer group, i.e., when we "reascend" from handling slaves of peer groups deeper down the propagation tree back to a slave mount that receives propagation in @dest_mnt's peer group so a slave mount in @dest_mnt's propagation group. So terminate on @source_mnt, easy peasy. Except, that it misses something what the rest of the algorithm already handles. If @dest_mnt has peers in it's peer group the first loop in propagate_mnt(): for (n = next_peer(dest_mnt); n != dest_mnt; n = next_peer(n)) { ret = propagate_one(n); if (ret) goto out; } will consecutively update @last_source such that after that loop terminates @last_source will point to whatever copy was created for the last peer in that peer group. It is however guaranteed that if there is a single additional peer in @dest_mnt's peer group that @last_source will __not__ point to @source_mnt anymore. Because, as we mentioned above, @dest_mnt isn't even handled in this loop but directly in attach_recursive_mnt(). So the first time we handle a slave mount @m of @dest_mnt's peer group the copy of @last_source we create will make the __last copy for the last peer in @dest_mnt's peer group__ we created the master of the copy that we now create for the first slave mount of @dest_mnt's peer group. But this means that the termination condition @source_mnt is wrong. The @source_mnt cannot be found anymore by propagate_one(). Instead it will find the copy we created for the last peer of @dest_mnt's peer group we processed in the earlier peer loop. And that is a peer of @source_mnt not @source_mnt itself. IOW, we fail to terminate the lookup loop for the source master and ultimately deref @last_source->mnt_master->mnt_parent when @last_source->mnt_master is NULL because @source_mnt and it's peers are pure shared mounts, i.e., they aren't slaves to another peer group. For example, assume @dest_mnt is a pure shared mount and has three peers: =================================================================================== mount-id mount-parent-id peer-group-id =================================================================================== (@dest_mnt) mnt_master[216] 309 297 shared:216 \ (@source_mnt) mnt_master[218]: 609 609 shared:218 (1) mnt_master[216]: 607 605 shared:216 \ (P1) mnt_master[218]: 624 607 shared:218 (2) mnt_master[216]: 576 574 shared:216 \ (P2) mnt_master[218]: 625 576 shared:218 (3) mnt_master[216]: 545 543 shared:216 \ (P3) mnt_master[218]: 626 545 shared:218 After this sequence has been processed @last_source will point to (P3), the copy generated for the third peer propagation we handled. So the first slave of @dest_mnt's peer group we handle: =================================================================================== mount-id mount-parent-id peer-group-id =================================================================================== mnt_master[216] 309 297 shared:216 / / (S0) mnt_slave 483 481 master:216 \ \ (P3) mnt_master[218] 626 545 shared:218 \ / \/ (P4) mnt_slave 627 483 master:218 we can see that (P3) will become the master of the copy of the new slave we created in propagation (P4) and mounted on top of the first slave (S0) of @dest_mnt. On any give walk through the @last_source master hierarchy we generate we may encounter (P3) but not @source_mnt itself. Ultimately leading to a NULL dereference. We can fix this in multiple ways. First, by setting: @last_source = @source_mnt after we processed the peers in @dest_mnt's peer group. Second, by changing the termination condition that relies on finding exactly @source_mnt to find a peer of @source_mnt. Third, by only moving @last_source when we actually venture into a new peer group. The latter is more intrusive but something I'd like to explore in the near future. Now, we just do the minimally correct thing. Passes LTP and specifically the mount propagation testsuite part of it and holds up against all reproducers. Final words... First, this is a clever but __worringly__ underdocumented algorithm. There isn't a single detailed comment to be found in next_group(), propagate_one() or anywhere else in that file for that matter. This has been a giant pain to understand and work through and a bug like this is insanely difficult to fix without detailed understanding of what's happening. Let's not talk about the amount of time that was sunk into fixing this. Second, all the cool kids with access to unshare --mount --user --map-root --propagation=unchanged are going to have a lot of fun.

[PATCH v2 0/2] maple_tree: Fix mas_spanning_rebalance() on

by Liam Howlett

Mike Rapoport contacted me off-list with a regression in running criu. Periodic tests fail with an RCU stall during execution. Although rare, it is possible to hit this with other uses so this patch should be backported to fix the regression. This patch set adds the fix and a test case to the maple tree test suite. Link: https://lore.kernel.org/linux-mm/20221216185233.2036415-1-Liam.Howlett@orac… V1 changes: - Add stable to CC list - Add tested-by to Mike's Reported-by. - Moved test case to its own commit since the test code was added after the fixed-by commit and isn't part of the fix.

[PATCH 5.4] xen-netback: move removal of "hotplug-status" to the right place

by Pratyush Yadav

The removal of "hotplug-status" has moved around a bit. First it was moved from netback_remove() to hotplug_status_changed() in upstream commit 1f2565780e9b ("xen-netback: remove 'hotplug-status' once it has served its purpose"). Then the change was reverted in upstream commit 0f4558ae9187 ("Revert "xen-netback: remove 'hotplug-status' once it has served its purpose""), but it moved the removal to backend_disconnect(). Then the upstream commit c55f34b6aec2 ("xen-netback: only remove 'hotplug-status' when the vif is actually destroyed") moved it finally back to netback_remove(). The thing to note being it is removed unconditionally this time around. The story on v5.4.y adds to this confusion. Commit 60e4e3198ce8 ("Revert "xen-netback: remove 'hotplug-status' once it has served its purpose"") is backported to v5.4.y but the original commit that it tries to revert was never present on 5.4. So the backport incorrectly ends up just adding another xenbus_rm() of "hotplug-status" in backend_disconnect(). Now in v5.4.y it is removed in both backend_disconnect() and netback_remove(). But it should only be removed in netback_remove(), as the upstream version does. Removing "hotplug-status" in backend_disconnect() causes problems when the frontend unilaterally disconnects, as explained in c55f34b6aec2 ("xen-netback: only remove 'hotplug-status' when the vif is actually destroyed"). Remove "hotplug-status" in the same place as it is done on the upstream version to ensure unilateral re-connection of frontend continues to work.

To simply fix it, we could just pass @sign kmalloc'd from crypt_message() and then we're done. Luckily, we don't seem to pass any other vmalloc'd buffers in smb_rqst::rq_iov...

To simply fix it, we could just pass @sign kmalloc'd from crypt_message() and then we're done. Luckily, we don't seem to pass any other vmalloc'd buffers in smb_rqst::rq_iov... Instead, let's map the correct pages and offsets from vmalloc buffers as well in cifs_sg_set_buf() and then avoiding such oopses.
