[PATCH net 0/5] mptcp: handle late ADD_ADDR + selftests skip

by Matthieu Baerts (NGI0)

Here are a few independent fixes related to MPTCP and its selftests: - Patch 1: correctly handle ADD_ADDR being received after the switch to 'fully-established'. A fix for another recent fix backported up to v5.14. - Patches 2-5: properly mark some MPTCP Join subtests as 'skipped' if the tested kernel doesn't support the feature being validated. Some fixes for up to v5.13, v5.18, v6.11 and v6.18-rc1 respectively.

[REGRESSION] Secureboot violation for linux enrolled by-hash into db v6.17.4 and v6.18-rc1

by Dimitri John Ledkov

If one enrolls linux kernel by-hash into db (for example using virt-fw-vars), the secureboot fails with security violation as EDK2 computation of authenticode for the linux binary doesn't match the enrolled hash. This is reproducible in AWS VMs, as well as locally with EDK2 builds with secureboot. Not affected v6.17 Not affected v6.17.3 Affected v6.17.4 Affected v6.18-rc1 Affected v6.18-rc2 Suspected patches are: $ git log --oneline v6.17.3..v6.17.4 -- scripts/ 8e5e13c8df9e6 kbuild: Add '.rel.*' strip pattern for vmlinux 7b80f81ae3190 kbuild: Restore pattern to avoid stripping .rela.dyn from vmlinux 5b5cdb1fe434e kbuild: keep .modinfo section in vmlinux.unstripped 86f364ee58420 kbuild: always create intermediate vmlinux.unstripped Reverting all of the above, makes secureboot with by-hash enrolled into db work again. I will try to bisect this further to determine the culprit. It feels like the strip potentially didn't update section offsets or their numbers or something like that. -- Regards, Dimitri.

[merged mm-hotfixes-stable] mm-damon-core-use-damos_commit_quota_goal-for-new-goal-commit.patch removed from -mm tree

The quilt patch titled Subject: mm/damon/core: use damos_commit_quota_goal() for new goal commit has been removed from the -mm tree. Its filename was mm-damon-core-use-damos_commit_quota_goal-for-new-goal-commit.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/core: use damos_commit_quota_goal() for new goal commit Date: Mon, 13 Oct 2025 17:18:44 -0700 When damos_commit_quota_goals() is called for adding new DAMOS quota goals of DAMOS_QUOTA_USER_INPUT metric, current_value fields of the new goals should be also set as requested. However, damos_commit_quota_goals() is not updating the field for the case, since it is setting only metrics and target values using damos_new_quota_goal(), and metric-optional union fields using damos_commit_quota_goal_union(). As a result, users could see the first current_value parameter that committed online with a new quota goal is ignored. Users are assumed to commit the current_value for DAMOS_QUOTA_USER_INPUT quota goals, since it is being used as a feedback. Hence the real impact would be subtle. That said, this is obviously not intended behavior. Fix the issue by using damos_commit_quota_goal() which sets all quota goal parameters, instead of damos_commit_quota_goal_union(), which sets only the union fields.

Its filename was vmw_balloon-indicate-success-when-effectively-deflating-during-migration.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: David Hildenbrand <david(a)redhat.com> Subject: vmw_balloon: indicate success when effectively deflating during migration Date: Tue, 14 Oct 2025 14:44:55 +0200 When migrating a balloon page, we first deflate the old page to then inflate the new page. However, if inflating the new page succeeded, we effectively deflated the old page, reducing the balloon size. In that case, the migration actually worked: similar to migrating+ immediately deflating the new page. The old page will be freed back to the buddy. Right now, the core will leave the page be marked as isolated (as we returned an error). When later trying to putback that page, we will run into the WARN_ON_ONCE() in balloon_page_putback(). That handling was changed in commit 3544c4faccb8 ("mm/balloon_compaction: stop using __ClearPageMovable()"); before that change, we would have tolerated that way of handling it. To fix it, let's just return 0 in that case, making the core effectively just clear the "isolated" flag + freeing it back to the buddy as if the migration succeeded. Note that the new page will also get freed when the core puts the last reference. Note that this also makes it all be more consistent: we will no longer unisolate the page in the balloon driver while keeping it marked as being isolated in migration core. This was found by code inspection.

The quilt patch titled Subject: mm/damon/core: fix list_add_tail() call on damon_call() has been removed from the -mm tree. Its filename was mm-damon-core-fix-list_add_tail-call-on-damon_call.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park <sj(a)kernel.org> Subject: mm/damon/core: fix list_add_tail() call on damon_call() Date: Tue, 14 Oct 2025 13:59:36 -0700 Each damon_ctx maintains callback requests using a linked list (damon_ctx->call_controls). When a new callback request is received via damon_call(), the new request should be added to the list. However, the function is making a mistake at list_add_tail() invocation: putting the new item to add and the list head to add it before, in the opposite order. Because of the linked list manipulation implementation, the new request can still be reached from the context's list head. But the list items that were added before the new request are dropped from the list. As a result, the callbacks are unexpectedly not invocated. Worse yet, if the dropped callback requests were dynamically allocated, the memory is leaked. Actually DAMON sysfs interface is using a dynamically allocated repeat-mode callback request for automatic essential stats update. And because the online DAMON parameters commit is using a non-repeat-mode callback request, the issue can easily be reproduced, like below. # damo start --damos_action stat --refresh_stat 1s # damo tune --damos_action stat --refresh_stat 1s The first command dynamically allocates the repeat-mode callback request for automatic essential stat update. Users can see the essential stats are automatically updated for every second, using the sysfs interface. The second command calls damon_commit() with a new callback request that was made for the commit. As a result, the previously added repeat-mode callback request is dropped from the list. The automatic stats refresh stops working, and the memory for the repeat-mode callback request is leaked. It can be confirmed using kmemleak. Fix the mistake on the list_add_tail() call.

While we always clear the VM_LOCKED and VM_LOCKONFAULT flags for the old mapping (the page tables have been moved, so there is no data that could possibly be locked in memory), there is no reason to touch any other VMA flags. This is because after the move the old mapping is in a state as if it were freshly mapped. This implies that the attributes of the mapping ought to remain the same, including whether or not the mapping is accounted.
