      powerpc64: Fix "show spr" command on ELFv2 kernels · 8f04c0c0
      Justin Hibbits authored
      Summary: When compiling for ELFv2, it is necessary to adjust the offset to
      get_spr and factor in the function prologue to ensure the correct instruction is
      being edited.
      Test Plan:

      powerpc/powernv: Restrict the busdma tag to only POWER8 · ad39591a
      Justin Hibbits authored
      It seems this tag is causing problems on POWER9 systems.  Since no POWER9 user
      has encountered the problem fixed by r339589 just restrict it to POWER8 for now.
      A better fix will likely be to update powerpc/busdma_machdep.c to handle the
      window correctly.

      Avoid buffer underwrite in icmp_error · 2bfaf585
      Ed Maste authored
      icmp_error allocates either an mbuf (with pkthdr) or a cluster depending
      on the size of data to be quoted in the ICMP reply, but the calculation
      failed to account for the additional padding that m_align may apply.
      Include the ip header in the size passed to m_align.  On 64-bit archs
      this will have the net effect of moving everything 4 bytes later in the
      mbuf or cluster.  This will result in slightly pessimal alignment for
      the ICMP data copy.
      Also add an assertion that we do not move m_data before the beginning of
      the mbuf or cluster.

      in6_ifattach_linklocal: handle immediate removal of the new LLA · 68b84087
      Eric van Gyzen authored
      If another thread immediately removes the link-local address
      added by in6_update_ifa(), in6ifa_ifpforlinklocal() can return NULL,
      so the following assertion (or dereference) is wrong.
      Remove the assertion, and handle NULL somewhat better than panicking.
      This matches all of the other callers of in6_update_ifa().

      ixl/iavf(4): Fix TSO offloads when TXCSUM is disabled · 37761e2e
      Eric Joyner authored
      From Jake:
      The iflib stack does not disable TSO automatically when TXCSUM is
      disabled, instead assuming that the driver will correctly handle TSOs
      even when CSUM_IP is not set.
      This results in iflib calling ixl_isc_txd_encap with packets which have
      CSUM_IP_TSO, but do not have CSUM_IP or CSUM_IP_TCP set. Because of
      this, ixl_tx_setup_offload will not setup the IPv4 checksum offloading.
      This results in bad TSO packets being sent if a user disables TXCSUM
      without disabling TSO.
      Fix this by updating the ixl_tx_setup_offload function to check both
      CSUM_IP and CSUM_IP_TSO when deciding whether to enable IPv4 checksums.
      Once this is corrected, another issue for TSO packets is revealed. The
      driver sets IFLIB_NEED_ZERO_CSUM in order to enable a work around that
      causes the ip->sum field to be zero'd. This is necessary for ixl
      hardware to correctly perform TSOs.
      However, if TXCSUM is disabled, then the work around is not enabled, as
      CSUM_IP will not be set when the iflib stack checks to see if it should
      clear the sum field.
      Fix this by adding IFLIB_TSO_INIT_IP to the iflib flags for the iavf and
      ixl interface files.
      It is uncertain if the hardware needs IFLIB_NEED_ZERO_CSUM for any other
      case besides TSO, so leave that flag assigned. It may be worth
      investigating to see if this work around flag could be disabled in
      a future change.
      Once both of these changes are made, the ixl driver should correctly
      offload TSO packets when TSO4 offload is enabled, regardless of whether
      TXCSUM is enabled or disabled.
