      ipv6: Fix Makefile offload objects · df484191
      Simon Arlott 提交于
      The following commit breaks IPv6 TCP transmission for me:
      	Commit 75fe83c3
      	Author: Vlad Yasevich <vyasevic@redhat.com>
      	Date:   Fri Nov 16 09:41:21 2012 +0000
      	ipv6: Preserve ipv6 functionality needed by NET
      
      This patch fixes the typo "ipv6_offload" which should be
      "ipv6-offload".
      
      I don't know why not including the offload modules should
      break TCP. Disabling all offload options on the NIC didn't
      help. Outgoing pulseaudio traffic kept stalling.

      cpts: Fix build error caused by include of plat/clock.h · e133b539
      Tony Lindgren 提交于
      Commit 87c0e764 (cpts: introduce time stamping code and a PTP hardware clock)
      mistakenly included plat/clock.h that should not be included by drivers
      even if it exists.
      
      Otherwise we get the following error with at least omap2plus_defconfig:
      
      drivers/net/ethernet/ti/cpts.c:30:24: error: plat/clock.h: No such file or directory

      This happens, because sk_clone_lock initializes sk_refcnt to 2, and thus
      a single sock_put() is not enough to free the memory. Additionally, things
      like xfrm, memcg, cookie_values,... may have been initialized.
      We have to free them properly.
      
      This is fixed by forcing a call to tcp_done(), ending up in
      inet_csk_destroy_sock, doing the final sock_put(). tcp_done() is necessary,
      because it ends up doing all the cleanup on xfrm, memcg, cookie_values,
      xfrm,...
      
      Before calling tcp_done, we have to set the socket to SOCK_DEAD, to
      force it entering inet_csk_destroy_sock. To avoid the warning in
      inet_csk_destroy_sock, inet_num has to be set to 0.
      As inet_csk_destroy_sock does a dec on orphan_count, we first have to
      increase it.
      
      Calling tcp_done() allows us to remove the calls to
      tcp_clear_xmit_timer() and tcp_cleanup_congestion_control().
      
      A similar approach is taken for dccp by calling dccp_done().
      
      This is in the kernel since 093d2823 (tproxy: fix hash locking issue
      when using port redirection in __inet_inherit_port()), thus since
      version >= 2.6.37.

      ipv6: Change skb->data before using icmpv6_notify() to propagate redirect · 093d04d4
      Duan Jiong 提交于
      In function ndisc_redirect_rcv(), the skb->data points to the transport
      header, but function icmpv6_notify() need the skb->data points to the
      inner IP packet. So before using icmpv6_notify() to propagate redirect,
      change skb->data to point the inner IP packet that triggered the sending
      of the Redirect, and introduce struct rd_msg to make it easy.
