Kernel Update Version:

Release Date:
2020-05-21 13:09:01
  • PSBM-104125

    packet: packet_sk_charge() could try to charge zero memory, leading to a use-after-free in memcg subsystem.

  • PSBM-103864

    memcg: potential use-after-free in the implementation of uncharge operations.

  • PSBM-102320

    qxl: kernel crash in qxl_release_fence_buffer_objects().

  • VSTOR-33397

    i40iw: kernel complains about failed RTNL assertion in i40iw_addr_resolve_neigh().

  • PSBM-103518

    Slow memory allocations in nf_conntrack when a netns is created.

    When a new netns is created, high-order page allocations can happen in nf_ct_alloc_hashtable(). If memory is fragmented, such allocations can become very slow due to memory reclaim, etc. This, in turn, could result in significant slowdowns on the node.
  • PSBM-102407

    nfsd: memory corruption in nfsd4_lock().

  • PSBM-102573

    Potential hard lockups in timer-related code: jiffies_lock could be held for a long time.

  • PSBM-102848

    (enhancement) ploop: added interface to dump the cached BAT.

    It was discovered that containers could get a broken on-disk BAT but have healthy in-kernel data in certain cases. To detect and fix such conditions, the means to dump the cached BAT were implemented in ploop. Note that, to make use of this enhancement, version 7.0.187.4 or newer of the userspace ploop tools is needed.
  • PSBM-102655

    netfilter: kernel crash in the implementation of nf_tables due to use-after-free in dynamic operations.

  • PSBM-102363

    A container with NFS server could force other such containers to use the older NFSv4 client tracker, which slows down NFS mounts.

  • PSBM-102478

    ext4: potential kernel crash (general protection fault) in ext4_free_blocks().

  • VSTOR-32221

    mpt2sas: scheduling while atomic in _scsih_io_done().
