ip6_mc_msfilter(): pass the address list separately

2020-05-21T00:31:29Z

that way we'll be able to reuse it for compat case Signed-off-by: Al Viro

ip*_mc_gsfget(): lift copyout of struct group_filter into callers

2020-05-21T00:31:27Z

pass the userland pointer to the array in its tail, so that part gets copied out by our functions; copyout of everything else is done in the callers. Rationale: reuse for compat; the array is the same in native and compat, the layout of parts before it is different for compat. Signed-off-by: Al Viro

ipv6: move SIOCADDRT and SIOCDELRT handling into ->compat_ioctl

2020-05-19T00:35:02Z

To prepare removing the global routing_ioctl hack start lifting the code into a newly added ipv6 ->compat_ioctl handler. Signed-off-by: Christoph Hellwig Signed-off-by: David S. Miller

net: UDP tunnel encapsulation module for tunnelling different protocols like MPLS, IP, NSH etc.

2020-02-24T21:31:42Z

The Bareudp tunnel module provides a generic L3 encapsulation tunnelling module for tunnelling different protocols like MPLS, IP,NSH etc inside a UDP tunnel. Signed-off-by: Martin Varghese Acked-by: Willem de Bruijn Signed-off-by: David S. Miller

mptcp: do not inherit inet proto ops

2020-01-25T07:14:39Z

We need to initialise the struct ourselves, else we expose tcp-specific callbacks such as tcp_splice_read which will then trigger splat because the socket is an mptcp one: BUG: KASAN: slab-out-of-bounds in tcp_mstamp_refresh+0x80/0xa0 net/ipv4/tcp_output.c:57 Write of size 8 at addr ffff888116aa21d0 by task syz-executor.0/5478 CPU: 1 PID: 5478 Comm: syz-executor.0 Not tainted 5.5.0-rc6 #3 Call Trace: tcp_mstamp_refresh+0x80/0xa0 net/ipv4/tcp_output.c:57 tcp_rcv_space_adjust+0x72/0x7f0 net/ipv4/tcp_input.c:612 tcp_read_sock+0x622/0x990 net/ipv4/tcp.c:1674 tcp_splice_read+0x20b/0xb40 net/ipv4/tcp.c:791 do_splice+0x1259/0x1560 fs/splice.c:1205 To prevent build error with ipv6, add the recv/sendmsg function declaration to ipv6.h. The functions are already accessible "thanks" to retpoline related work, but they are currently only made visible by socket.c specific INDIRECT_CALLABLE macros.
