      NET: usb: qmi_wwan: add support for Telit LE922A PID 0x1040 · 9bd813da
      Daniele Palmas authored
      This patch adds support for PID 0x1040 of Telit LE922A.
      
      The qmi adapter requires to have DTR set for proper working,
      so QMI_WWAN_QUIRK_DTR has been enabled.

      cdc_ether: Fix handling connection notification · d5c83d0d
      Kristian Evensen authored
      Commit bfe9b9d2 ("cdc_ether: Improve ZTE MF823/831/910 handling")
      introduced a work-around in usbnet_cdc_status() for devices that exported
      cdc carrier on twice on connect. Before the commit, this behavior caused
      the link state to be incorrect. It was assumed that all CDC Ethernet
      devices would either export this behavior, or send one off and then one on
      notification (which seems to be the default behavior).
      
      Unfortunately, it turns out multiple devices sends a connection
      notification multiple times per second (via an interrupt), even when
      connection state does not change. This has been observed with several
      different USB LAN dongles (at least), for example 13b1:0041 (Linksys).
      After bfe9b9d2, the link state has been set as down and then up for
      each notification. This has caused a flood of Netlink NEWLINK messages and
      syslog to be flooded with messages similar to:
      
      cdc_ether 2-1:2.0 eth1: kevent 12 may have been dropped
      
      This commit fixes the behavior by reverting usbnet_cdc_status() to how it
      was before bfe9b9d2. The work-around has been moved to a separate
      status-function which is only called when a known, affect device is
      detected.
      
      v1->v2:
      
      * Do not open-code netif_carrier_ok() (thanks Henning Schild).
      * Call netif_carrier_off() instead of usb_link_change(). This prevents
      calling schedule_work() twice without giving the work queue a chance to be
      processed (thanks Bjørn Mork).

      ipv6: Set skb->protocol properly for local output · b4e479a9

      packet: fix race condition in packet_set_ring · 84ac7260
      Philip Pettersson authored
      When packet_set_ring creates a ring buffer it will initialize a
      struct timer_list if the packet version is TPACKET_V3. This value
      can then be raced by a different thread calling setsockopt to
      set the version to TPACKET_V1 before packet_set_ring has finished.
      
      This leads to a use-after-free on a function pointer in the
      struct timer_list when the socket is closed as the previously
      initialized timer will not be deleted.
      
      The bug is fixed by taking lock_sock(sk) in packet_setsockopt when
      changing the packet version while also taking the lock at the start
      of packet_set_ring.

      net: ethernet: altera: TSE: do not use tx queue lock in tx completion handler · 2219d5ed
      Lino Sanfilippo authored
      The driver already uses its private lock for synchronization between xmit
      and xmit completion handler making the additional use of the xmit_lock
      unnecessary.
      Furthermore the driver does not set NETIF_F_LLTX resulting in xmit to be
      called with the xmit_lock held and then taking the private lock while xmit
      completion handler does the reverse, first take the private lock, then the
      xmit_lock.
      Fix these issues by not taking the xmit_lock in the tx completion handler.

      ====================
      net: stmmac: fix probe error handling and phydev leaks
      
      This series fixes a number of issues with the stmmac-driver probe error
      handling, which for example left clocks enabled after probe failures.
      
      The final patch fixes a failure to deregister and free any fixed-link
      PHYs that were registered during probe on probe errors and on driver
      unbind. It also fixes a related of-node leak on late probe errors.
      
      This series depends on the of_phy_deregister_fixed_link() helper that
      was just merged to net.
      
      As mentioned earlier, one staging driver also suffers from a similar
      leak and can be fixed up once the above mentioned helper hits mainline.
      
      Note that these patches have only been compile tested.

      ixgbe/ixgbevf: Don't use lco_csum to compute IPv4 checksum · c54cdc31
      Alexander Duyck authored
      In the case of IPIP and SIT tunnel frames the outer transport header
      offset is actually set to the same offset as the inner transport header.
      This results in the lco_csum call not doing any checksum computation over
      the inner IPv4/v6 header data.
      
      In order to account for that I am updating the code so that we determine
      the location to start the checksum ourselves based on the location of the
      IPv4 header and the length.

      1) Change the error value when someone tries to run 32bit
         userspace on a 64bit host from -ENOTSUPP to the userspace
         exported -EOPNOTSUPP. Fix from Yi Zhao.
      
      2) On inbound, ESN sequence numbers are already in network
         byte order. So don't try to convert it again, this fixes
         integrity verification for ESN. Fixes from Tobias Brunner.
      
      Please pull or let me know if there are problems.

      ====================
      Netfilter fixes for net
      
      This is a large batch of Netfilter fixes for net, they are:
      
      1) Three patches to fix NAT conversion to rhashtable: Switch to rhlist
         structure that allows to have several objects with the same key.
         Moreover, fix wrong comparison logic in nf_nat_bysource_cmp() as this is
         expecting a return value similar to memcmp(). Change location of
         the nat_bysource field in the nf_conn structure to avoid zeroing
         this as it breaks interaction with SLAB_DESTROY_BY_RCU and lead us
         to crashes. From Florian Westphal.
      
      2) Don't allow malformed fragments go through in IPv6, drop them,
         otherwise we hit GPF, patch from Florian Westphal.
      
      3) Fix crash if attributes are missing in nft_range, from Liping Zhang.
      
      4) Fix arptables 32-bits userspace 64-bits kernel compat, from Hongxu Jia.
      
      5) Two patches from David Ahern to fix netfilter interaction with vrf.
         From David Ahern.
      
      6) Fix element timeout calculation in nf_tables, we take milliseconds
         from userspace, but we use jiffies from kernelspace. Patch from
         Anders K.  Pedersen.
      
      7) Missing validation length netlink attribute for nft_hash, from
         Laura Garcia.
      
      8) Fix nf_conntrack_helper documentation, we don't default to off
         anymore for a bit of time so let's get this in sync with the code.
      
      I know is late but I think these are important, specifically the NAT
      bits, as they are mostly addressing fallout from recent changes. I also
      read there are chances to have -rc8, if that is the case, that would
      also give us a bit more time to test this.
