      RDMA/cma: Fix unknown symbol when CONFIG_IPV6 is not enabled · b4cfe397
      Jack Morgenstein 提交于
      If IPV6 has not been enabled in the underlying kernel, we must avoid
      calling IPV6 procedures in rdma_cm.ko.
      
      This requires using "IS_ENABLED(CONFIG_IPV6)" in "if" statements
      surrounding any code which calls external IPV6 procedures.
      
      In the instance fixed here, procedure cma_bind_addr() called
      ipv6_addr_type() -- which resulted in calling external procedure
      __ipv6_addr_type().

      xfs: prevent quotacheck from overloading inode lru · e0d76fa4
      Brian Foster 提交于
      Quotacheck runs at mount time in situations where quota accounting must
      be recalculated. In doing so, it uses bulkstat to visit every inode in
      the filesystem. Historically, every inode processed during quotacheck
      was released and immediately tagged for reclaim because quotacheck runs
      before the superblock is marked active by the VFS. In other words,
      the final iput() lead to an immediate ->destroy_inode() call, which
      allowed the XFS background reclaim worker to start reclaiming inodes.
      
      Commit 17c12bcd ("xfs: when replaying bmap operations, don't let
      unlinked inodes get reaped") marks the XFS superblock active sooner as
      part of the mount process to support caching inodes processed during log
      recovery. This occurs before quotacheck and thus means all inodes
      processed by quotacheck are inserted to the LRU on release.  The
      s_umount lock is held until the mount has completed and thus prevents
      the shrinkers from operating on the sb. This means that quotacheck can
      excessively populate the inode LRU and lead to OOM conditions on systems
      without sufficient RAM.
      
      Update the quotacheck bulkstat handler to set XFS_IGET_DONTCACHE on
      inodes processed by quotacheck. This causes ->drop_inode() to return 1
      and in turn causes iput_final() to evict the inode. This preserves the
      original quotacheck behavior and prevents it from overloading the LRU
      and running out of memory.

      net: adjust skb->truesize in pskb_expand_head() · 158f323b
      Eric Dumazet 提交于
      Slava Shwartsman reported a warning in skb_try_coalesce(), when we
      detect skb->truesize is completely wrong.
      
      In his case, issue came from IPv6 reassembly coping with malicious
      datagrams, that forced various pskb_may_pull() to reallocate a bigger
      skb->head than the one allocated by NIC driver before entering GRO
      layer.
      
      Current code does not change skb->truesize, leaving this burden to
      callers if they care enough.
      
      Blindly changing skb->truesize in pskb_expand_head() is not
      easy, as some producers might track skb->truesize, for example
      in xmit path for back pressure feedback (sk->sk_wmem_alloc)
      
      We can detect the cases where it should be safe to change
      skb->truesize :
      
      1) skb is not attached to a socket.
      2) If it is attached to a socket, destructor is sock_edemux()
      
      My audit gave only two callers doing their own skb->truesize
      manipulation.
      
      I had to remove skb parameter in sock_edemux macro when
      CONFIG_INET is not set to avoid a compile error.

      parsing packet headers.  (VXLAN and GENEVE will only be recognised if the
      driver on the primary PF has notified the firmware of relevant UDP ports,
      which this driver does not yet do.)
      While the driver currently has no way of using these filters for flow
      steering, it is nonetheless necessary to insert catch-all (aka 'default')
      filters to direct this traffic, similar to the existing unencapsulated uni-
      and multi-cast catch-all filters, as otherwise the traffic will be dropped
      by the NIC - implementation details of the hardware filtering mean that the
      traffic will not get matched on outer MAC address to unencapsulated catch-
      all filters.  (Yes, this is a mess.)
      Although this is, therefore, fixing a bug in the existing driver, it's a bug
      which has existed since 8000 series support was added, and the fix involves
      quite a big patch with an 'adding features' flavour to it, hence why this is
      for net-next rather than net and stable.

      sfc: insert catch-all filters for encapsulated traffic · 9b410801
      Edward Cree 提交于
      8000 series adapters support filtering VXLAN, NVGRE and GENEVE traffic
       based on inner fields, and when the NIC recognises such traffic, it
       does not match unencapsulated traffic filters any more.  So add catch-
       all filters for encapsulated traffic on supporting platforms.
      Although recognition of VXLAN and GENEVE is based on UDP ports, and thus
       will not occur until the driver (on the primary PF) notifies the
       firmware of UDP ports to use, NVGRE will always be recognised, hence
       without this patch 8000 series adapters will drop all NVGRE traffic.

      For reporting things that may or may not be serious, depending on some

       at either dbg (if the condition is true) or the specified level.

      sfc: fixes to filter restore handling · 2d3d4ec0
      Jon Cooper 提交于
      If the NIC is switched from full-featured to low-latency, encapsulated
       filters are no longer available, and this causes errors. This patch
       removes those filters from the filter table on restore.
      Also, if filters which are removed by the above, or which we fail to
       insert when restoring filters, were UC, MC or broadcast default
       filters, invalidate the corresponding vlan->default_filters entry.

      ISDN: eicon: silence misleading array-bounds warning · 950eabbd
      Arnd Bergmann 提交于
      With some gcc versions, we get a warning about the eicon driver,
      and that currently shows up as the only remaining warning in one
      of the build bots:
      
      In file included from ../drivers/isdn/hardware/eicon/message.c:30:0:
      eicon/message.c: In function 'mixer_notify_update':
      eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds]
      
      The code is easily changed to open-code the unusual PUT_WORD() line
      causing this to avoid the warning.

      pull-request: can-next 2017-01-24
      
      this is a pull request of 4 patches for net-next/master.
      
      The first patch by Oliver Hartkopp adds a netlink API to configure the
      interface termination of a CAN card. The next two patches are by me and
      add a netlink API to query and configure CAN interfaces that only
      support fixed bitrates. The last patch by Colin Ian King simplifies the
      return path in the softing_cs driver's softingcs_probe() function.
