This reverts commit dde3c6b72a16c2db826f54b2d49bdea26c3534a2. syzbot report a double-free bug. The following case can cause this bug. - mm/slab_common.c: create_cache(): if the __kmem_cache_create() fails, it does: out_free_cache: kmem_cache_free(kmem_cache, s); - but __kmem_cache_create() - at least for slub() - will have done sysfs_slab_add(s) -> sysfs_create_group() .. fails .. -> kobject_del(&s->kobj); .. which frees s ... We can't remove the kmem_cache_free() in create_cache(), because other error cases of __kmem_cache_create() do not free this. So, revert the commit dde3c6b72a16 ("mm/slub: fix a memory leak in sysfs_slab_add()") to fix this.

2021-01-28block: fix bd_size_lock useDamien Le Moal2-4/+7
Some block device drivers, e.g. the skd driver, call set_capacity() with IRQ disabled. This results in lockdep ito complain about inconsistent lock states ("inconsistent {HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage") because set_capacity takes a block device bd_size_lock using the functions spin_lock() and spin_unlock(). Ensure a consistent locking state by replacing these calls with spin_lock_irqsave() and spin_lock_irqrestore(). The same applies to bdev_set_nr_sectors(). With this fix, all lockdep complaints are resolved. Signed-off-by: Damien Le Moal <[email protected]> Signed-off-by: Jens Axboe <[email protected]>
2021-01-28blk-cgroup: Use cond_resched() when destroy blkgsBaolin Wang1-5/+13
On !PREEMPT kernel, we can get below softlockup when doing stress testing with creating and destroying block cgroup repeatly. The reason is it may take a long time to acquire the queue's lock in the loop of blkcg_destroy_blkgs(), or the system can accumulate a huge number of blkgs in pathological cases. We can add a need_resched() check on each loop and release locks and do cond_resched() if true to avoid this issue, since the blkcg_destroy_blkgs() is not called from atomic contexts.

2021-01-28iommu/vt-d: Do not use flush-queue when caching-mode is onNadav Amit1-1/+31
When an Intel IOMMU is virtualized, and a physical device is passed-through to the VM, changes of the virtual IOMMU need to be propagated to the physical IOMMU. The hypervisor therefore needs to monitor PTE mappings in the IOMMU page-tables. Intel specifications provide "caching-mode" capability that a virtual IOMMU uses to report that the IOMMU is virtualized and a TLB flush is needed after mapping to allow the hypervisor to propagate virtual IOMMU mappings to the physical IOMMU. To the best of my knowledge no real physical IOMMU reports "caching-mode" as turned on. Synchronizing the virtual and the physical IOMMU tables is expensive if the hypervisor is unaware which PTEs have changed, as the hypervisor is required to walk all the virtualized tables and look for changes. Consequently, domain flushes are much more expensive than page-specific flushes on virtualized IOMMUs with passthrough devices. The kernel therefore exploited the "caching-mode" indication to avoid domain flushing and use page-specific flushing in virtualized environments. See commit 78d5f0f500e6 ("intel-iommu: Avoid global flushes with caching mode.") This behavior changed after commit 13cf01744608 ("iommu/vt-d: Make use of iova deferred flushing"). Now, when batched TLB flushing is used (the default), full TLB domain flushes are performed frequently, requiring the hypervisor to perform expensive synchronization between the virtual TLB and the physical one. Getting batched TLB flushes to use page-specific invalidations again in such circumstances is not easy, since the TLB invalidation scheme assumes that "full" domain TLB flushes are performed for scalability. Disable batched TLB flushes when caching-mode is on, as the performance benefit from using batched TLB invalidations is likely to be much smaller than the overhead of the virtual-to-physical IOMMU page-tables synchronization.

2021-01-28iommu/amd: Use IVHD EFR for early initialization of IOMMU featuresSuravee Suthikulpanit3-7/+60
IOMMU Extended Feature Register (EFR) is used to communicate the supported features for each IOMMU to the IOMMU driver. This is normally read from the PCI MMIO register offset 0x30, and used by the iommu_feature() helper function. However, there are certain scenarios where the information is needed prior to PCI initialization, and the iommu_feature() function is used prematurely w/o warning. This has caused incorrect initialization of IOMMU. This is the case for the commit 6d39bdee238f ("iommu/amd: Enforce 4k mapping for certain IOMMU data structures") Since, the EFR is also available in the IVHD header, and is available to the driver prior to PCI initialization. Therefore, default to using the IVHD EFR instead.

2021-01-28ovl: implement volatile-specific fsync error behaviourSargun Dhillon7-11/+71
Overlayfs's volatile option allows the user to bypass all forced sync calls to the upperdir filesystem. This comes at the cost of safety. We can never ensure that the user's data is intact, but we can make a best effort to expose whether or not the data is likely to be in a bad state. The best way to handle this in the time being is that if an overlayfs's upperdir experiences an error after a volatile mount occurs, that error will be returned on fsync, fdatasync, sync, and syncfs. This is contradictory to the traditional behaviour of VFS which fails the call once, and only raises an error if a subsequent fsync error has occurred, and been raised by the filesystem. One awkward aspect of the patch is that we have to manually set the superblock's errseq_t after the sync_fs callback as opposed to just returning an error from syncfs. This is because the call chain looks something like this: sys_syncfs -> sync_filesystem -> __sync_filesystem -> /* The return value is ignored here sb->s_op->sync_fs(sb) _sync_blockdev /* Where the VFS fetches the error to raise to userspace */ errseq_check_and_advance Because of this we call errseq_set every time the sync_fs callback occurs. Due to the nature of this seen / unseen dichotomy, if the upperdir is an inconsistent state at the initial mount time, overlayfs will refuse to mount, as overlayfs cannot get a snapshot of the upperdir's errseq that will increment on error until the user calls syncfs.

2021-01-28ovl: skip getxattr of security labelsAmir Goldstein1-7/+8
When inode has no listxattr op of its own (e.g. squashfs) vfs_listxattr calls the LSM inode_listsecurity hooks to list the xattrs that LSMs will intercept in inode_getxattr hooks. When selinux LSM is installed but not initialized, it will list the security.selinux xattr in inode_listsecurity, but will not intercept it in inode_getxattr. This results in -ENODATA for a getxattr call for an xattr returned by listxattr. This situation was manifested as overlayfs failure to copy up lower files from squashfs when selinux is built-in but not initialized, because ovl_copy_xattr() iterates the lower inode xattrs by vfs_listxattr() and vfs_getxattr(). ovl_copy_xattr() skips copy up of security labels that are indentified by inode_copy_up_xattr LSM hooks, but it does that after vfs_getxattr(). Since we are not going to copy them, skip vfs_getxattr() of the security labels.

The function ovl_dir_real_file() currently uses the inode lock to serialize writes to the od->upperfile field. However, this function will get called by ovl_ioctl_set_flags(), which utilizes the inode lock too. In this case ovl_dir_real_file() will try to claim a lock that is owned by a function in its call stack, which won't get released before ovl_dir_real_file() returns.

2021-01-28KVM: x86: fix CPUID entries returned by KVM_GET_CPUID2 ioctlMichael Roth1-1/+1
Recent commit 255cbecfe0 modified struct kvm_vcpu_arch to make 'cpuid_entries' a pointer to an array of kvm_cpuid_entry2 entries rather than embedding the array in the struct. KVM_SET_CPUID and KVM_SET_CPUID2 were updated accordingly, but KVM_GET_CPUID2 was missed. As a result, KVM_GET_CPUID2 currently returns random fields from struct kvm_vcpu_arch to userspace rather than the expected CPUID values. Fix this by treating 'cpuid_entries' as a pointer when copying its contents to userspace buffer.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net 1) Honor stateful expressions defined in the set from the dynset extension. The set definition provides a stateful expression that must be used by the dynset expression in case it is specified. 2) Missing timeout extension in the set element in the dynset extension leads to inconsistent ruleset listing, not allowing the user to restore timeout and expiration on ruleset reload. 3) Do not dump the stateful expression from the dynset extension if it coming from the set definition. * git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf: netfilter: nft_dynset: dump expressions when set definition contains no expressions netfilter: nft_dynset: add timeout extension to template netfilter: nft_dynset: honor stateful expressions in set definition ==================== Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
