      l2tp: fix manual sequencing (de)activation in L2TPv2 · bb5016ea
      Guillaume Nault 提交于
      Commit e0d4435f "l2tp: Update PPP-over-L2TP driver to work over L2TPv3"
      broke the PPPOL2TP_SO_SENDSEQ setsockopt. The L2TP header length was
      previously computed by pppol2tp_l2t_header_len() before each call to
      l2tp_xmit_skb(). Now that header length is retrieved from the hdr_len
      session field, this field must be updated every time the L2TP header
      format is modified, or l2tp_xmit_skb() won't push the right amount of
      data for the L2TP header.
      
      This patch uses l2tp_session_set_header_len() to adjust hdr_len every
      time sequencing is (de)activated from userspace (either by the
      PPPOL2TP_SO_SENDSEQ setsockopt or the L2TP_ATTR_SEND_SEQ netlink
      attribute).

      ipv6: make lookups simpler and faster · efe4208f
      Eric Dumazet 提交于
      TCP listener refactoring, part 4 :
      
      To speed up inet lookups, we moved IPv4 addresses from inet to struct
      sock_common
      
      Now is time to do the same for IPv6, because it permits us to have fast
      lookups for all kind of sockets, including upcoming SYN_RECV.
      
      Getting IPv6 addresses in TCP lookups currently requires two extra cache
      lines, plus a dereference (and memory stall).
      
      inet6_sk(sk) does the dereference of inet_sk(__sk)->pinet6
      
      This patch is way bigger than its IPv4 counter part, because for IPv4,
      we could add aliases (inet_daddr, inet_rcv_saddr), while on IPv6,
      it's not doable easily.
      
      inet6_sk(sk)->daddr becomes sk->sk_v6_daddr
      inet6_sk(sk)->rcv_saddr becomes sk->sk_v6_rcv_saddr
      
      And timewait socket also have tw->tw_v6_daddr & tw->tw_v6_rcv_saddr
      at the same offset.
      
      We get rid of INET6_TW_MATCH() as INET6_MATCH() is now the generic
      macro.

      l2tp: fix kernel panic when using IPv4-mapped IPv6 addresses · e18503f4
      François Cachereul 提交于
      IPv4 mapped addresses cause kernel panic.
      The patch juste check whether the IPv6 address is an IPv4 mapped
      address. If so, use IPv4 API instead of IPv6.

      hlist: drop the node parameter from iterators · b67bfe0d
      Sasha Levin 提交于
      I'm not sure why, but the hlist for each entry iterators were conceived
      
              list_for_each_entry(pos, head, member)
      
      The hlist ones were greedy and wanted an extra parameter:
      
              hlist_for_each_entry(tpos, pos, head, member)
      
      Why did they need an extra pos parameter? I'm not quite sure. Not only
      they don't really need it, it also prevents the iterator from looking
      exactly like the list iterator, which is unfortunate.
      
      Besides the semantic patch, there was some manual work required:
      
       - Fix up the actual hlist iterators in linux/list.h
       - Fix up the declaration of other iterators based on the hlist ones.
       - A very small amount of places were using the 'node' parameter, this
       was modified to use 'obj->member' instead.
       - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
       properly, so those had to be fixed up manually.
      
      The semantic patch which is mostly the work of Peter Senna Tschudin is here:

      Playing with skb->truesize is tricky, especially when
      skb is attached to a socket, as we can fool memory charging.
      
      Just remove this code, its not worth trying to be ultra
      precise in xmit path.

      l2tp: prevent l2tp_tunnel_delete racing with userspace close · 80d84ef3
      Tom Parkin 提交于
      If a tunnel socket is created by userspace, l2tp hooks the socket destructor
      in order to clean up resources if userspace closes the socket or crashes.  It
      also caches a pointer to the struct sock for use in the data path and in the
      netlink interface.
      
      While it is safe to use the cached sock pointer in the data path, where the
      skb references keep the socket alive, it is not safe to use it elsewhere as
      such access introduces a race with userspace closing the socket.  In
      particular, l2tp_tunnel_delete is prone to oopsing if a multithreaded
      userspace application closes a socket at the same time as sending a netlink
      delete command for the tunnel.
      
      This patch fixes this oops by forcing l2tp_tunnel_delete to explicitly look up
      a tunnel socket held by userspace using sockfd_lookup().
