[patch 157/163] mm/hugetlb: fix calculation of adjust_range_if_pmd_sharing_possible

by Andrew Morton

From: Peter Xu <peterx(a)redhat.com> Subject: mm/hugetlb: fix calculation of adjust_range_if_pmd_sharing_possible This is found by code observation only. Firstly, the worst case scenario should assume the whole range was covered by pmd sharing. The old algorithm might not work as expected for ranges like (1g-2m, 1g+2m), where the adjusted range should be (0, 1g+2m) but the expected range should be (0, 2g). Since at it, remove the loop since it should not be required. With that, the new code should be faster too when the invalidating range is huge. Mike said: : With range (1g-2m, 1g+2m) within a vma (0, 2g) the existing code will only : adjust to (0, 1g+2m) which is incorrect. : : We should cc stable. The original reason for adjusting the range was to : prevent data corruption (getting wrong page). Since the range is not : always adjusted correctly, the potential for corruption still exists. : : However, I am fairly confident that adjust_range_if_pmd_sharing_possible : is only gong to be called in two cases: : : 1) for a single page : 2) for range == entire vma : : In those cases, the current code should produce the correct results. : : To be safe, let's just cc stable.

[patch 093/163] mm/page_counter.c: fix protection usage propagation

by Andrew Morton

From: Michal Koutný <mkoutny(a)suse.com> Subject: mm/page_counter.c: fix protection usage propagation When workload runs in cgroups that aren't directly below root cgroup and their parent specifies reclaim protection, it may end up ineffective. The reason is that propagate_protected_usage() is not called in all hierarchy up. All the protected usage is incorrectly accumulated in the workload's parent. This means that siblings_low_usage is overestimated and effective protection underestimated. Even though it is transitional phenomenon (uncharge path does correct propagation and fixes the wrong children_low_usage), it can undermine the intended protection unexpectedly. We have noticed this problem while seeing a swap out in a descendant of a protected memcg (intermediate node) while the parent was conveniently under its protection limit and the memory pressure was external to that hierarchy. Michal has pinpointed this down to the wrong siblings_low_usage which led to the unwanted reclaim. The fix is simply updating children_low_usage in respective ancestors also in the charging path.

[patch 004/163] mm: fix kthread_use_mm() vs TLB invalidate

by Andrew Morton

From: Peter Zijlstra <peterz(a)infradead.org> Subject: mm: fix kthread_use_mm() vs TLB invalidate For SMP systems using IPI based TLB invalidation, looking at current->active_mm is entirely reasonable. This then presents the following race condition: CPU0 CPU1 flush_tlb_mm(mm) use_mm(mm) <send-IPI> tsk->active_mm = mm; <IPI> if (tsk->active_mm == mm) // flush TLBs </IPI> switch_mm(old_mm,mm,tsk); Where it is possible the IPI flushed the TLBs for @old_mm, not @mm, because the IPI lands before we actually switched. Avoid this by disabling IRQs across changing ->active_mm and switch_mm(). Of the (SMP) architectures that have IPI based TLB invalidate: Alpha - checks active_mm ARC - ASID specific IA64 - checks active_mm MIPS - ASID specific flush OpenRISC - shoots down world PARISC - shoots down world SH - ASID specific SPARC - ASID specific x86 - N/A xtensa - checks active_mm So at the very least Alpha, IA64 and Xtensa are suspect. On top of this, for scheduler consistency we need at least preemption disabled across changing tsk->mm and doing switch_mm(), which is currently provided by task_lock(), but that's not sufficient for PREEMPT_RT.

[patch 003/163] mm/shuffle: don't move pages between zones and don't read garbage memmaps

by Andrew Morton

From: David Hildenbrand <david(a)redhat.com> Subject: mm/shuffle: don't move pages between zones and don't read garbage memmaps Especially with memory hotplug, we can have offline sections (with a garbage memmap) and overlapping zones. We have to make sure to only touch initialized memmaps (online sections managed by the buddy) and that the zone matches, to not move pages between zones. To test if this can actually happen, I added a simple BUG_ON(page_zone(page_i) != page_zone(page_j)); right before the swap. When hotplugging a 256M DIMM to a 4G x86-64 VM and onlining the first memory block "online_movable" and the second memory block "online_kernel", it will trigger the BUG, as both zones (NORMAL and MOVABLE) overlap. This might result in all kinds of weird situations (e.g., double allocations, list corruptions, unmovable allocations ending up in the movable zone).

XXX moar > > Fixes: fd7d55172d1e ("perf/cgroups: Don't rotate events for cgroups unnecessarily") Can this patch (commit 90c91dfb86d0 ("perf/core: Fix endless multiplex timer") upstream) be applied to stable please? For PMU drivers built as modules, the bug can actually kill the system, since the runaway hrtimer loop keeps calling pmu->{enable,disable} after all the events have been closed and dropped their references to pmu->module. Thus legitimately unloading the module once things have got into this state quickly results in a crash when those callbacks disappear. (FWIW I spent about two days fighting with this while testing a new driver as a module against the 5.3 kernel installed on someone else's machine, assuming it was a bug in my code...)

[PATCH] scripts: add dummy report mode to add_namespace.cocci

by Matthias Maennich

When running `make coccicheck` in report mode using the add_namespace.cocci file, it will fail for files that contain MODULE_LICENSE. Those match the replacement precondition, but spatch errors out as virtual.ns is not set. In order to fix that, add the virtual rule nsdeps and only do search and replace if that rule has been explicitly requested. In order to make spatch happy in report mode, we also need a dummy rule, as otherwise it errors out with "No rules apply". Using a script:python rule appears unrelated and odd, but this is the shortest I could come up with. Adjust scripts/nsdeps accordingly to set the nsdeps rule when run trough `make nsdeps`.
