[merged] fork-memcg-fix-cached_stacks-case.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: fork, memcg: fix cached_stacks case has been removed from the -mm tree. Its filename was fork-memcg-fix-cached_stacks-case.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Shakeel Butt <shakeelb(a)google.com> Subject: fork, memcg: fix cached_stacks case 5eed6f1dff87 ("fork,memcg: fix crash in free_thread_stack on memcg charge fail") fixes a crash caused due to failed memcg charge of the kernel stack. However the fix misses the cached_stacks case which this patch fixes. So, the same crash can happen if the memcg charge of a cached stack is failed.

[PATCH 4.9] libceph: fix CEPH_FEATURE_CEPHX_V2 check in calc_signature()

by Ilya Dryomov

Upstream commit cc255c76c70f ("libceph: implement CEPHX_V2 calculation mode") was adjusted incorrectly: CEPH_FEATURE_CEPHX_V2 if condition got inverted, thus breaking 4.9.144 and later kernels for all setups that use cephx.

If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From e1c3743e1a20647c53b719dbf28b48f45d23f2cd Mon Sep 17 00:00:00 2001 From: Breno Leitao <leitao(a)debian.org> Date: Wed, 21 Nov 2018 17:21:09 -0200 Subject: [PATCH] powerpc/tm: Set MSR[TS] just prior to recheckpoint On a signal handler return, the user could set a context with MSR[TS] bits set, and these bits would be copied to task regs->msr. At restore_tm_sigcontexts(), after current task regs->msr[TS] bits are set, several __get_user() are called and then a recheckpoint is executed. This is a problem since a page fault (in kernel space) could happen when calling __get_user(). If it happens, the process MSR[TS] bits were already set, but recheckpoint was not executed, and SPRs are still invalid. The page fault can cause the current process to be de-scheduled, with MSR[TS] active and without tm_recheckpoint() being called. More importantly, without TEXASR[FS] bit set also. Since TEXASR might not have the FS bit set, and when the process is scheduled back, it will try to reclaim, which will be aborted because of the CPU is not in the suspended state, and, then, recheckpoint. This recheckpoint will restore thread->texasr into TEXASR SPR, which might be zero, hitting a BUG_ON(). kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434! cpu 0xb: Vector: 700 (Program Check) at [c00000041f1576d0] pc: c000000000054550: restore_gprs+0xb0/0x180 lr: 0000000000000000 sp: c00000041f157950 msr: 8000000100021033 current = 0xc00000041f143000 paca = 0xc00000000fb86300 softe: 0 irq_happened: 0x01 pid = 1021, comm = kworker/11:1 kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434!

With this patch, the MSR[TS] will only be set just before recheckpointing and setting TEXASR[FS] = 1, thus avoiding an interrupt with TM registers in invalid state. Other than that, if CONFIG_PREEMPT is set, there might be a preemption just after setting MSR[TS] and before tm_recheckpoint(), thus, this block must be atomic from a preemption perspective, thus, calling preempt_disable/enable() on this code. It is not possible to move tm_recheckpoint to happen earlier, because it is required to get the checkpointed registers from userspace, with __get_user(), thus, the only way to avoid this undesired behavior is delaying the MSR[TS] set. The 32-bits signal handler seems to be safe this current issue, but, it might be exposed to the preemption issue, thus, disabling preemption in this chunk of code.

At restore_tm_sigcontexts(), after current task regs->msr[TS] bits are set, several __get_user() are called and then a recheckpoint is executed. This is a problem since a page fault (in kernel space) could happen when calling __get_user(). If it happens, the process MSR[TS] bits were already set, but recheckpoint was not executed, and SPRs are still invalid. The page fault can cause the current process to be de-scheduled, with MSR[TS] active and without tm_recheckpoint() being called. More importantly, without TEXASR[FS] bit set also. Since TEXASR might not have the FS bit set, and when the process is scheduled back, it will try to reclaim, which will be aborted because of the CPU is not in the suspended state, and, then, recheckpoint. This recheckpoint will restore thread->texasr into TEXASR SPR, which might be zero, hitting a BUG_ON(). kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434! cpu 0xb: Vector: 700 (Program Check) at [c00000041f1576d0] pc: c000000000054550: restore_gprs+0xb0/0x180 lr: 0000000000000000 sp: c00000041f157950 msr: 8000000100021033 current = 0xc00000041f143000 paca = 0xc00000000fb86300 softe: 0 irq_happened: 0x01 pid = 1021, comm = kworker/11:1 kernel BUG at /build/linux-sf3Co9/linux-4.9.30/arch/powerpc/kernel/tm.S:434!

[PATCH] mm, slab, memcg: call memcg kmem put cache with same condition as get

by Rik van Riel

There is an imbalance between when slab_pre_alloc_hook calls memcg_kmem_get_cache and when slab_post_alloc_hook calls memcg_kmem_put_cache. This can cause a memcg kmem cache to be destroyed right as an object from that cache is being allocated, which is probably not good. It could lead to things like a memcg allocating new kmalloc slabs instead of using freed space in old ones, maybe memory leaks, and maybe oopses as a memcg kmalloc slab is getting destroyed on one CPU while another CPU is trying to do an allocation from that same memcg. The obvious fix would be to use the same condition for calling memcg_kmem_put_cache that we also use to decide whether to call memcg_kmem_get_cache. I am not sure how long this bug has been around, since the last changeset to touch that code - 452647784b2f ("mm: memcontrol: cleanup kmem charge functions") - merely moved the bug from one location to another. I am still tagging that changeset, because the fix should automatically apply that far back.

[PATCH, stable-v4.14] KVM: arm/arm64: Fix VMID alloc race by reverting to lock-less

by Christoffer Dall

Commit fb544d1ca65a89f7a3895f7531221ceeed74ada7 upstream. We recently addressed a VMID generation race by introducing a read/write lock around accesses and updates to the vmid generation values. However, kvm_arch_vcpu_ioctl_run() also calls need_new_vmid_gen() but does so without taking the read lock. As far as I can tell, this can lead to the same kind of race: VM 0, VCPU 0 VM 0, VCPU 1 ------------ ------------ update_vttbr (vmid 254) update_vttbr (vmid 1) // roll over read_lock(kvm_vmid_lock); force_vm_exit() local_irq_disable need_new_vmid_gen == false //because vmid gen matches enter_guest (vmid 254) kvm_arch.vttbr = <PGD>:<VMID 1> read_unlock(kvm_vmid_lock); enter_guest (vmid 1) Which results in running two VCPUs in the same VM with different VMIDs and (even worse) other VCPUs from other VMs could now allocate clashing VMID 254 from the new generation as long as VCPU 0 is not exiting. Attempt to solve this by making sure vttbr is updated before another CPU can observe the updated VMID generation.

[patch 11/14] mm: page_mapped: don't assume compound page is huge or THP

by akpm＠linux-foundation.org

From: Jan Stancek <jstancek(a)redhat.com> Subject: mm: page_mapped: don't assume compound page is huge or THP LTP proc01 testcase has been observed to rarely trigger crashes on arm64: page_mapped+0x78/0xb4 stable_page_flags+0x27c/0x338 kpageflags_read+0xfc/0x164 proc_reg_read+0x7c/0xb8 __vfs_read+0x58/0x178 vfs_read+0x90/0x14c SyS_read+0x60/0xc0 Issue is that page_mapped() assumes that if compound page is not huge, then it must be THP. But if this is 'normal' compound page (COMPOUND_PAGE_DTOR), then following loop can keep running (for HPAGE_PMD_NR iterations) until it tries to read from memory that isn't mapped and triggers a panic: for (i = 0; i < hpage_nr_pages(page); i++) { if (atomic_read(&page[i]._mapcount) >= 0) return true; } I could replicate this on x86 (v4.20-rc4-98-g60b548237fed) only with a custom kernel module [1] which: - allocates compound page (PAGEC) of order 1 - allocates 2 normal pages (COPY), which are initialized to 0xff (to satisfy _mapcount >= 0) - 2 PAGEC page structs are copied to address of first COPY page - second page of COPY is marked as not present - call to page_mapped(COPY) now triggers fault on access to 2nd COPY page at offset 0x30 (_mapcount) [1] https://github.com/jstancek/reproducers/blob/master/kernel/page_mapped_cras… Fix the loop to iterate for "1 << compound_order" pages.

More precisely task1 is handling a page fault and it has a page locked while it charges a new page table to a memcg. That in turn hits a memory limit reclaim and the memcg reclaim for legacy controller is waiting on the writeback but that is never going to finish because the writeback itself is waiting for the page locked in the #PF path. So this is essentially ABBA deadlock: lock_page(A) SetPageWriteback(A) unlock_page(A) lock_page(B) lock_page(B) pte_alloc_pne shrink_page_list wait_on_page_writeback(A) SetPageWriteback(B) unlock_page(B) # flush A, B to clear the writeback This accumulating of more pages to flush is used by several filesystems to generate a more optimal IO patterns. Waiting for the writeback in legacy memcg controller is a workaround for pre-mature OOM killer invocations because there is no dirty IO throttling available for the controller. There is no easy way around that unfortunately. Therefore fix this specific issue by pre-allocating the page table outside of the page lock. We have that handy infrastructure for that already so simply reuse the fault-around pattern which already does this. There are probably other hidden __GFP_ACCOUNT | GFP_KERNEL allocations from under a fs page locked but they should be really rare. I am not aware of a better solution unfortunately.

[patch 04/14] mm/usercopy.c: no check page span for stack objects
