      Bluetooth: Fix potential NULL dereference · 88d9077c
      Johan Hedberg authored
      
      
      The bnep_get_device function may be triggered by an ioctl just after a
      connection has gone down. In such a case the respective L2CAP chan->conn
      pointer will get set to NULL (by l2cap_chan_del). This patch adds a
      missing NULL check for this case in the bnep_get_device() function.

      Firmware for 04ca:2007 can be extracted from the latest Lenovo E145
      Bluetooth driver for Windows (driver is however described as BCM20702
      but contains also firwmare for BCM43142).
      Search for BCM43142A0_001.001.011.0122.0153.hex within hex files, then
      it must be converted using hex2hcd utility. Rename file to
      BCM43142A0-04ca-2007.hcd, then move to /lib/firmware/brcm/.

      net: sctp: Deletion of an unnecessary check before the function call "kfree" · 7d37d0c1
      Markus Elfring authored
      
      
      The kfree() function tests whether its argument is NULL and then
      returns immediately. Thus the test around the call is not needed.
      
      This issue was detected by using the Coccinelle software.

      Merge branch 'udpv6_lockless_send' · 193cdc4a

      ipv6: Add lockless UDP send path
      
      This series introduces a lockless UDPv6 send path similar to
      what Herbert Xu did for IPv4 a while ago.
      
      There are some difference from IPv4.  IPv6 caching for flow
      label is a bit different, as well as it requires another cork
      cork structure that holds the IPv6 ancillary data.
      
      Please take a look.

      ipv6: Allow for partial checksums on non-ufo packets · 32dce968
      Vlad Yasevich authored
      
      
      Currntly, if we are not doing UFO on the packet, all UDP
      packets will start with CHECKSUM_NONE and thus perform full
      checksum computations in software even if device support
      IPv6 checksum offloading.
      
      Let's start start with CHECKSUM_PARTIAL if the device
      supports it and we are sending only a single packet at
      or below mtu size.

      udpv6: Add lockless sendmsg() support · 03485f2a

      This commit adds the same functionaliy to IPv6 that
      commit 903ab86d
      
      
      Author: Herbert Xu <herbert@gondor.apana.org.au>

          udp: Add lockless transmit path
      
      added to IPv4.
      
      UDP transmit path can now run without a socket lock,
      thus allowing multiple threads to send to a single socket
      more efficiently.
      This is only used when corking/MSG_MORE is not used.

      ipv6: Introduce udpv6_send_skb() · d39d938c
      Vlad Yasevich authored
      
      
      Now that we can individually construct IPv6 skbs to send, add a
      udpv6_send_skb() function to populate the udp header and send the
      skb.  This allows udp_v6_push_pending_frames() to re-use this
      function as well as enables us to add lockless sendmsg() support.

      ipv6: introduce ipv6_make_skb · 6422398c
      Vlad Yasevich authored
      This commit is very similar to
      commit 1c32c5ad
      
      
      Author: Herbert Xu <herbert@gondor.apana.org.au>
      Date:   Tue Mar 1 02:36:47 2011 +0000
      
          inet: Add ip_make_skb and ip_finish_skb
      
      It adds IPv6 version of the helpers ip6_make_skb and ip6_finish_skb.
      
      The job of ip6_make_skb is to collect messages into an ipv6 packet
      and poplulate ipv6 eader.  The job of ip6_finish_skb is to transmit
      the generated skb.  Together they replicated the job of
      ip6_push_pending_frames() while also provide the capability to be
      called independently.  This will be needed to add lockless UDP sendmsg
      support.
