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

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.
