[PATCH 1/3] udf: Detect incorrect directory size

by Jan Kara

Detect when a directory entry is (possibly partially) beyond directory size and return EIO in that case since it means the filesystem is corrupted. Otherwise directory operations can further corrupt the directory and possibly also oops the kernel.

[Linux-stable-mirror] [PATCH] MIPS: Fix arch_trigger_cpumask_backtrace()

by Huacai Chen

SysRq-L and RCU stall detector call arch_trigger_cpumask_backtrace() to trigger other CPU's backtrace, but its behavior is totally broken. The root cause is arch_trigger_cpumask_backtrace() use call-function IPI in irq context, which trigger deadlocks in smp_call_function_single() and smp_call_function_many(). This patch fix arch_trigger_cpumask_backtrace() by: 1, Use a dedecated IPI (SMP_CPU_BACKTRACE) to trigger backtraces; 2, If myself is in target cpumask, do backtrace and clear myself; 3, Use a spinlock to avoid parallel backtrace output; 4, Handle SMP_CPU_BACKTRACE IPI for Loongson-3. I have attempted to implement SMP_CPU_BACKTRACE for all MIPS CPUs, but I failed because some of their IPIs are not extensible. :( Cc: stable(a)vger.kernel.org Signed-off-by: Huacai Chen <chenhc(a)lemote.com> --- arch/mips/include/asm/smp.h | 3 +++ arch/mips/kernel/process.c | 23 ++++++++++++++++++----- arch/mips/loongson64/loongson-3/smp.c | 6 ++++++ 3 files changed, 27 insertions(+), 5 deletions(-) diff --git a/arch/mips/include/asm/smp.h b/arch/mips/include/asm/smp.h index 88ebd83..b0521f4 100644 --- a/arch/mips/include/asm/smp.h +++ b/arch/mips/include/asm/smp.h @@ -43,6 +43,7 @@ extern int __cpu_logical_map[NR_CPUS]; /* Octeon - Tell another core to flush its icache */ #define SMP_ICACHE_FLUSH 0x4 #define SMP_ASK_C0COUNT 0x8 +#define SMP_CPU_BACKTRACE 0x10 /* Mask of CPUs which are currently definitely operating coherently */ extern cpumask_t cpu_coherent_mask; @@ -81,6 +82,8 @@ static inline void __cpu_die(unsigned int cpu) extern void play_dead(void); #endif +void arch_dump_stack(void); + /* * This function will set up the necessary IPIs for Linux to communicate * with the CPUs in mask. diff --git a/arch/mips/kernel/process.c b/arch/mips/kernel/process.c index 57028d4..647e15d 100644 --- a/arch/mips/kernel/process.c +++ b/arch/mips/kernel/process.c @@ -655,26 +655,39 @@ unsigned long arch_align_stack(unsigned long sp) return sp & ALMASK; } -static void arch_dump_stack(void *info) +void arch_dump_stack(void) { struct pt_regs *regs; + static arch_spinlock_t lock = __ARCH_SPIN_LOCK_UNLOCKED; + arch_spin_lock(&lock); regs = get_irq_regs(); if (regs) show_regs(regs); dump_stack(); + arch_spin_unlock(&lock); } void arch_trigger_cpumask_backtrace(const cpumask_t *mask, bool exclude_self) { long this_cpu = get_cpu(); + struct cpumask backtrace_mask; + extern const struct plat_smp_ops *mp_ops; + + cpumask_copy(&backtrace_mask, mask); + if (cpumask_test_cpu(this_cpu, mask)) { + if (!exclude_self) { + struct pt_regs *regs = get_irq_regs(); + if (regs) + show_regs(regs); + dump_stack(); + } + cpumask_clear_cpu(this_cpu, &backtrace_mask); + } - if (cpumask_test_cpu(this_cpu, mask) && !exclude_self) - dump_stack(); - - smp_call_function_many(mask, arch_dump_stack, NULL, 1); + mp_ops->send_ipi_mask(&backtrace_mask, SMP_CPU_BACKTRACE); put_cpu(); } diff --git a/arch/mips/loongson64/loongson-3/smp.c b/arch/mips/loongson64/loongson-3/smp.c index 8501109..0655114 100644 --- a/arch/mips/loongson64/loongson-3/smp.c +++ b/arch/mips/loongson64/loongson-3/smp.c @@ -291,6 +291,12 @@ void loongson3_ipi_interrupt(struct pt_regs *regs) __wbflush(); /* Let others see the result ASAP */ } + if (action & SMP_CPU_BACKTRACE) { + irq_enter(); + arch_dump_stack(); + irq_exit(); + } + if (irqs) { int irq; while ((irq = ffs(irqs))) { -- 2.7.0

+ slub-fix-failure-when-we-delete-and-create-a-slab-cache.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: slub: fix failure when we delete and create a slab cache has been added to the -mm tree. Its filename is slub-fix-failure-when-we-delete-and-create-a-slab-cache.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/slub-fix-failure-when-we-delete-an… and later at http://ozlabs.org/~akpm/mmotm/broken-out/slub-fix-failure-when-we-delete-an… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Mikulas Patocka <mpatocka(a)redhat.com> Subject: slub: fix failure when we delete and create a slab cache In kernel 4.17 I removed some code from dm-bufio that did slab cache merging (21bb13276768) - both slab and slub support merging caches with identical attributes, so dm-bufio now just calls kmem_cache_create and relies on implicit merging. This uncovered a bug in the slub subsystem - if we delete a cache and immediatelly create another cache with the same attributes, it fails because of duplicate filename in /sys/kernel/slab/. The slub subsystem offloads freeing the cache to a workqueue - and if we create the new cache before the workqueue runs, it complains because of duplicate filename in sysfs. This patch fixes the bug by moving the call of kobject_del from sysfs_slab_remove_workfn to shutdown_cache. kobject_del must be called while we hold slab_mutex - so that the sysfs entry is deleted before a cache with the same attributes could be created.

[merged] mm-fix-devmem_is_allowed-for-sub-page-system-ram-intersections.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: fix devmem_is_allowed() for sub-page System RAM intersections has been removed from the -mm tree.

Then I saw the following warning in dmesg. I saved it and rebooted immediately. memremap attempted on mixed range 0x000000000009c000 size: 0x1000 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 11810 at kernel/memremap.c:98 memremap+0x104/0x170 [..] Call Trace: xlate_dev_mem_ptr+0x25/0x40 read_mem+0x89/0x1a0 __vfs_read+0x36/0x170 The memremap() implementation checks for attempts to remap System RAM with MEMREMAP_WB and instead redirects those mapping attempts to the linear map. However, that only works if the physical address range being remapped is page aligned. In low memory we have situations like the following: 00000000-00000fff : Reserved 00001000-0009fbff : System RAM 0009fc00-0009ffff : Reserved ...where System RAM intersects Reserved ranges on a sub-page page granularity. Given that devmem_is_allowed() special cases any attempt to map System RAM in the first 1MB of memory, replace page_is_ram() with the more precise region_intersects() to trap attempts to map disallowed ranges.

Thus it will cause exceptions in handle_hva_to_gpa on arm64. This patch fixes it by ignoring (not removing) the low bits of address when doing rmap_walk_ksm. IMO, it should be backported to stable tree. the stom of WARN_ONs is very easy for me to reproduce.

Andrea said: : It looks a straightforward safe fix, on x86 hva_to_gfn_memslot would : zap those bits and hide the misalignment caused by the low metadata : bits being erroneously left set in the address, but the arm code : notices when that's the last page in the memslot and the hva_end is : getting aligned and the size is below one page. : : I think the problem triggers in the addr += PAGE_SIZE of : unmap_stage2_ptes that never matches end because end is aligned but : addr is not. : : } while (pte++, addr += PAGE_SIZE, addr != end); : : x86 again only works on hva_start/hva_end after converting it to : gfn_start/end and that being in pfn units the bits are zapped before : they risk to cause trouble. Jia He said: : I've tested by myself in arm64 server (QDF2400,46 cpus,96G mem) Without : this patch, the WARN_ON is very easy for reproducing. After this patch, I : have run the same benchmarch for a whole day without any WARN_ONs Link: http://lkml.kernel.org/r/1525403506-6750-1-git-send-email-hejianet@gmail.com Signed-off-by: Jia He <jia.he(a)hxt-semitech.com> Reviewed-by: Andrea Arcangeli <aarcange(a)redhat.com> Tested-by: Jia He <hejianet(a)gmail.com> Cc: Suzuki K Poulose <Suzuki.Poulose(a)arm.com> Cc: Minchan Kim <minchan(a)kernel.org> Cc: Claudio Imbrenda <imbrenda(a)linux.vnet.ibm.com> Cc: Arvind Yadav <arvind.yadav.cs(a)gmail.com> Cc: Mike Rapoport <rppt(a)linux.vnet.ibm.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- mm/ksm.c | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) diff -puN mm/ksm.c~mm-ksm-ignore-stable_flag-of-rmap_item-address-in-rmap_walk_ksm mm/ksm.c --- a/mm/ksm.c~mm-ksm-ignore-stable_flag-of-rmap_item-address-in-rmap_walk_ksm +++ a/mm/ksm.c @@ -216,6 +216,8 @@ struct rmap_item { #define SEQNR_MASK 0x0ff /* low bits of unstable tree seqnr */ #define UNSTABLE_FLAG 0x100 /* is a node of the unstable tree */ #define STABLE_FLAG 0x200 /* is listed from the stable tree */ +#define KSM_FLAG_MASK (SEQNR_MASK|UNSTABLE_FLAG|STABLE_FLAG) + /* to mask all the flags */ /* The stable and unstable tree heads */ static struct rb_root one_stable_tree[1] = { RB_ROOT }; @@ -2598,10 +2600,15 @@ again: anon_vma_lock_read(anon_vma); anon_vma_interval_tree_foreach(vmac, &anon_vma->rb_root, 0, ULONG_MAX) { + unsigned long addr; + cond_resched(); vma = vmac->vma; - if (rmap_item->address < vma->vm_start || - rmap_item->address >= vma->vm_end) + + /* Ignore the stable/unstable/sqnr flags */ + addr = rmap_item->address & ~KSM_FLAG_MASK; + + if (addr < vma->vm_start || addr >= vma->vm_end) continue; /* * Initially we examine only the vma which covers this @@ -2615,8 +2622,7 @@ again: if (rwc->invalid_vma && rwc->invalid_vma(vma, rwc->arg)) continue; - if (!rwc->rmap_one(page, vma, - rmap_item->address, rwc->arg)) { + if (!rwc->rmap_one(page, vma, addr, rwc->arg)) { anon_vma_unlock_read(anon_vma); return; } _ Patches currently in -mm which might be from jia.he(a)hxt-semitech.com are

[PATCH 1/3] um: Drop own definition of PTRACE_SYSEMU/_SINGLESTEP

by Richard Weinberger

32bit UML used to define PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP own its own because many years ago not all libcs had these request codes in their UAPI. These days PTRACE_SYSEMU/_SINGLESTEP is well known and part of glibc and our own define becomes problematic. With change c48831d0eebf ("linux/x86: sync sys/ptrace.h with Linux 4.14 [BZ #22433]") glibc turned PTRACE_SYSEMU/_SINGLESTEP into a enum and UML failed to build. Let's drop our define and rely on the fact that every libc has PTRACE_SYSEMU/_SINGLESTEP.

Re: x86/fpu: Disable AVX when eagerfpu is off

by Julian Stecklina

Yu, Regarding your patch to disable AVX with eager fpu disabled in the 4.4 stable queue: https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tre… Why would this be necessary? In the Intel SDM Vol 2, Chapter 2.4, FPU/SIMD instructions are grouped into different classes and for all of them CR0.TS triggers a #NM exception in all modes but real mode and virtual 8086 mode. It seems to me lazy context switching of AVX is perfectly functional (disregarding the recently disclosed security issue). Am I missing something? Julian

This could cause its size to be bigger than that of the modulus, making the HW complain: caam_jr 2142000.jr1: 40000789: DECO: desc idx 7: Protocol Size Error - A protocol has seen an error in size. When running RSA, pdb size N < (size of F) when no formatting is used; or pdb size N < (F + 11) when formatting is used. Fix the problem by stripping off the leading zero from input data before feeding it to the CAAM accelerator.

[PATCH] block: do not use interruptible wait anywhere

by Khalid Elmously

From: Alan Jenkins <alan.christopher.jenkins(a)gmail.com> BugLink: http://bugs.launchpad.net/bugs/1776887 When blk_queue_enter() waits for a queue to unfreeze, or unset the PREEMPT_ONLY flag, do not allow it to be interrupted by a signal. The PREEMPT_ONLY flag was introduced later in commit 3a0a529971ec ("block, scsi: Make SCSI quiesce and resume work reliably"). Note the SCSI device is resumed asynchronously, i.e. after un-freezing userspace tasks. So that commit exposed the bug as a regression in v4.15. A mysterious SIGBUS (or -EIO) sometimes happened during the time the device was being resumed. Most frequently, there was no kernel log message, and we saw Xorg or Xwayland killed by SIGBUS.[1] [1] E.g. https://bugzilla.redhat.com/show_bug.cgi?id=1553979 Without this fix, I get an IO error in this test: # dd if=/dev/sda of=/dev/null iflag=direct & \ while killall -SIGUSR1 dd; do sleep 0.1; done & \ echo mem > /sys/power/state ; \ sleep 5; killall dd # stop after 5 seconds The interruptible wait was added to blk_queue_enter in commit 3ef28e83ab15 ("block: generic request_queue reference counting"). Before then, the interruptible wait was only in blk-mq, but I don't think it could ever have been correct.
